How to reduce erroneous Emergency Department admissions for the frail elderly

Background

Readmission after a first hospitalization is a common occurrence. It may be due to incomplete treatment, poor care for underlying problems or reflect bad coordination with health services at the time of discharge. The aim of this study was to identify the factors and classify the pathologies that expose elderly patients to erroneous access to the Emergency/Urgency Department (EUD).

Study design

Retrospective observational study.

Materials and methods

From January 2016 to December 2019 we studied patients who had at least one readmission to the EUD in the six months following discharge. All EUD accesses of the same patient that occurred for the problem treated during the previous hospitalization were identified. Data was provided by the University Hospital of Siena. Patients were stratified by age, gender, and municipality of residence. We used an ICD-9-CM coding system to describe health problems. Statistical analysis was carried out with Stata software.

Results

We studied 1,230 patients (46.6% females) the mean age was 78.2 ± 14.3. Most of them, 721 (58.6%) were ≥80 years old, 334 (27.1%) were 65-79, 138 (11.2%) were 41-64, and only 37 (3.0%) were ≤40. Patients who lived in Municipality of Siena had a lower probability to return than to those living in other municipalities (OR 0.76; 95%CI: 0.62-0.93; p<0,05). The main causes of readmission for ≥65 years old were "symptoms, signs and ill-defined conditions" (18.3%), "respiratory diseases" (15.0%), "injury and poisoning" (14.1%), "cardiovascular diseases" (11.8%), "classification of factors influencing health status and contact with health services" (9.8%), "genitourinary diseases" (6.6%) and "digestive diseases (5.7%).

Conclusions

We observed that patients residing a greater distance from the hospital facilitates the risk of readmission. The factors that were exposed could be used to identify frequent users and initiate measures to reduce their access.

Disinfecting Slush Machines by an Innovative Near Ultraviolet Light Emitting Diode (UV LED) Technological System

Background

Microbial contamination of food and beverages is a topic of great interest. The most innovative technologies take advantage from UV light. This study aimed to evaluate a possible configuration of a nUV LED device at a wavelength of 405 nm installed on slush machines in order to reduce the microbial contamination.

Study Design and Methods

Study Design and Methods. The study was conducted in the Department of Molecular and Developmental Medicine, University of Siena, Italy. A nUV LED device with 408 nm wavelength was installed and used on the slush machines. The inner walls of the machine tanks were fouled with contaminated slush, to evaluate the effectiveness of nUV radiation in reducing microbial contamination over time.

Results

Experiment results on the slush machine showed a statistically significant logarithmic microbial reduction, in relation with the distance from the nUV LED light source. It has also been shown that the reduction of microbes is possible with a proper management of some parameters: the exposure time, the power and wavelength of the light source, the distance and the obstacles between the light source and the target to be irradiated.

Conclusion

To reduce the incidence of foodborne diseases it is necessary to take all necessary precautionary measures, and the use of nUV technology has proved to be a crucial element in achieving this goal.

Effectiveness of near-UVA in SARS-CoV-2 inactivation

This experimental study aimed to determine the activity of a near-UVA (405 nm) LED ceiling system against the SARS-CoV-2 virus. The ceiling system comprised 17 near-UVA LED lights with a radiant power of 1.1 W/each centred at 405 nm wavelength. A 96-multiwell plate, fixed to a wooden base, was inoculated with suspensions of VERO E6 cell cultures infected with SARS-CoV-2 virus and irradiated at a distance of 40 cm with a dose of 20.2 J/cm² for 120 min. The collected suspensions were transferred to VERO cell culture plates and incubated for 3 days. The maximum measurable log reduction obtained, starting from a concentration of 10^7.2 TCID50/mL, was 3.0 log₁₀ and indicated inhibition of SARS-CoV-2 replication by the near-UVA LED ceiling system. Near-UVA light at a 405-nm wavelength is emerging as a potential alternative treatment for localised infections and environmental decontamination because it is far less harmful to living organisms' cells than UV-C irradiation.

Safer school with near-UV technology: novel applications for environmental hygiene

Systems capable of disinfecting air and surfaces could reduce the risk of infectious diseases transmission. Aim: to evaluate the effectiveness of near-UV LED ceiling lamps, with a wavelength of 405 nm, in improving environmental hygiene. Between November and December 2020, we conducted an experimental study having a pre-post design in a kindergarten room in Siena where 4 ceiling lamps with 405 nm LED technology were installed. Twice per day, sampling was performed before (T0) and after treatment with near-UV (T1). We used between 8 and 12 pairs of contact plates to sample at various random spots each day. Air samplings were also performed. The plates were incubated at 22 and 36 °C. Significance was set at 95% (p < 0.05). The mean level of Colony Forming Unit (CFU) at T(0) was 249 (95% CI 193.1 - 305.0) at 36 °C and 535.2 (374.3 - 696.1) at 22 °C. The reduction was significant at T(1): by 65% at 36 °C and, 72% at 22 °C. Also, for air contamination: 95.3% (98.4-92.3). A dose threshold of about 5 J/cm² was identified to have an 80% CFU abatement and remains nearly constant. The advantage of being able to use this technology in the presence of people is very important in the context of controlling environmental contamination.

Factors influencing the first thousand days of life

Background

The first 1000 days are crucial for the health of the baby and the well-being of the mother-baby dyad, which forms a single complex organism with its co-metabolism expressed through sophisticated neurobiological, epigenetic and microbiome development mechanisms. This study aims to investigate how much social support can influence the path of pregnancy and motherhood.

Methods

The retrospective observational study was conducted on a sample of mothers enrolled through social networks who were administered a questionnaire from July to September 2021. The questionnaire consisted of 37 questions: 11 analyzed sociodemographic variables, 20 were on current / any previous pregnancies and breastfeeding, and 6 were used to calculate the Maternity Social Support Scale (MSSS-Webster et al.). STATA 14 was used for statistical analysis.

Results

Our sample consisted of 3447 women. 88.0% wanted the pregnancy, and 63.5% planned it. The average of the Maternity Social Support Scale (MSSS) was 23.91 points. A low MSSS score correlates with a higher risk of cessation of breastfeeding before 6 months of age, a higher risk of not having spontaneous labour, a higher risk of cesarean section and a higher risk of not having a spontaneous birth. On the other hand, a higher MSSS total score is a protective factor concerning breastfeeding duration, which is more likely to be longer-lasting (>6 months), to have spontaneous onset labour with a higher probability of spontaneous delivery.

Conclusions

The results showed that most of our sample have good friends who support them, can often count on their family, and receive help from their partner/husband. The outcomes of pregnancy, childbirth and motherhood are strongly influenced and conditioned by the social context in which they occur and the support the woman can receive. The presence or lack of this support can affect the health of newborns.

Key messages

• The first 1,000 days is a vulnerable phase in which parents, institutions and health professionals should create early interventions for the proper development and promotion of good health.

• the outcomes of pregnancy, birth and motherhood are strongly influenced and conditioned by the social context, but especially by the presence or lack of support that can affect the health of newborns.

How to improve the rehabilitation outcome after total knee replacement?

Background

Even if total knee replacement has revolutionized the treatment of degenerative knee diseases, the definition of an ideal rehabilitation protocol is still in progress. The aim of this study is to identify the factors that influence the outcomes after early, intensive, hospitalized treatment.

Methods

A retrospective study was conducted in 2019 on 545 patients admitted to a northern Italy private clinic specialized in post-surgery rehabilitation, which applies a bio-psycho-social-environmental model and individual rehabilitation plans. Data regarding each patient were collected from medical records: age, numeric pain rating scale (NPRS) at admission, days between surgery and the beginning of rehabilitation (DBS). The outcomes were measured as the difference (Δ) between the values at discharge and admission of the Barthel scale (ΔBS), Tinetti scale (ΔTS), passive flexion (ΔPF) and active flexion (ΔAF). We performed a univariate linear regression through STATA, to determine which factors influence the outcomes. A p &lt; 0.05 was considered statistically significant.

Results

Our sample (69.17% female) was 69.8 ± 9.4 years old. ΔBS was significantly influenced by age (Coef. 0.270, CI [0.173 - 0.367]) and NPRS (Coef. 1.434, CI [0.979 - 1.890]). ΔTS was significantly influenced by age (Coef. 0.024, CI [0.011 - 0.037]) and NPRS (Coef. 0.130, CI [0.067 - 0.191]). ΔPF was significantly influenced by age (Coef. - 0.158, CI [- 0.266 - - 0.050]), DBS (Coef. - 1.047, CI [- 1.401 - - 0.687]) and NPRS (Coef. 1.825, CI [1.333 - 2.318]). ΔAF was significantly influenced by age (Coef. - 0.171, CI [- 0.300 - - 0.042]), DBS (Coef. - 1.150, CI [- 1.580 - - 0.721]) and NPRS (Coef. 2.504, CI [1.928 - 3.080]).

Conclusions

Older patients obtain a higher functional outcome (ΔBS, ΔTS) but lower improvement in range of motion (ΔPF, ΔAF). Patients with higher NPRS at admission obtain an overall better outcome. Higher DBS is associated to lower articular outcomes (ΔPF, ΔAF).

Key messages

• A better outcome can be achieved if rehabilitation is started immediately after knee replacement.

• Pain and age are not factors that impede effective rehabilitation.

Is it really possible to leave sars-cov-2 outside the door?

Background

In this historical period, it has become very important to live in healthy environments. By using everyday objects, cross-contamination is possible because of prolonged microbial persistence on surfaces. UV-C irradiation is an environmentally friendly method to disinfect objects as no harmful chemicals or heat are involved. This study aims to determine the virucidal activity, against SARS-CoV-2, of UV-C irradiation occurring in a designed UV device, ‘Purity Capsule'.

Methods

An experimental study was performed in September 2020. The ‘Purity capsule’ has an 11 W lamp (3.5W UV-C) positioned in the centre of the device. The lamp has a dome covered with a reflective, protective coating. Three metal carriers were placed at the maximum distance from the UV-C lamp in three different positions and tested at 30 and 60 seconds 3 times. The carriers were inoculated with 100 µL of SARS-CoV-2 viral suspension with a concentration of 106.5 TCID50 /mL. After treatment, laboratory procedures were used to transfer the treated virus from carriers to multiwell plates. The samples were compared with positive controls (not exposed to UV-C light) after incubation, at 37 °C in 5% COÕ · in a humidified atmosphere, for 3 days. The residual viral activity was tested by assessing the 50% infectious dose per tissue culture (TCID50%).

Results

Tests performed at 30 seconds of UV-C irradiation show an average viral reduction of 4.0 Log10 (99.99%). All three tests performed at 60 seconds reached the maximum measurable log10 viral reduction: 5.0 Log10 (99.999%).

Conclusions

The study assessed the effectiveness of the device in significantly reducing the viral load on all carriers regardless exposure time and distance from the UV-C light source, with no impact on the level of environmental pollution.

Key messages

• UV-C light has the property of inactivating viral growth; its physical approach is considered a good compromise between cost and effectiveness.

• The device was effective in disinfecting all small everyday objects tested.

Promote equal access to COVID19 vaccination: strategies of the Local Authority Toscana SudEst, Italy

Background

In the area of the Local Health Authority Toscana Sud-Est (LHA) 13,5% of residents are foreigners. We aim to assess the impact of our intervention to COVID-19 vaccination coverage.

Methods

Since summer 2021, LHA has promoted vaccination sessions dedicated to foreign residents with free walk-in access, multilingual forms, flyers and TV interventions, cultural mediators and trained healthcare workers. We collected data about vaccination status of residents (28 December 2020-31 January 2022) and we analysed them using the software STATA to assess vaccine coverage by nationality and the effectiveness of our intervention. The results were adjusted for age and sex. We set significance level at p &lt; 0.05.

Results

On 31 July 2021, 78% of Italian residents (N = 685289) had received the first dose of vaccine, compared to only 43% of foreign residents (N = 106370). There was a 35% gap. On 31 January 2022, after our intervention, 89% of Italian residents and 71% of foreign residents had received the first dose of the vaccine. The gap was 18%. On 31 January 2022, 50% of residents of all nationalities had received two doses of the vaccine. A significant difference between Italian and foreign residents is still observed after adjustment for age and sex (OR 0.41 95% IC 0.40-0.41). Vaccination adherence is lower in females than males, for both Italian (OR 0.90 0.89-0.91) and foreign residents (OR 0.82 0.79-0.84). This is accentuated within some ethnic groups: Macedonians, Kosovars, Pakistanis.

Conclusions

The creation of dedicated service guaranteed to reach a high vaccination coverage in all the nationalities and to reduce the gap between host and foreign residents. In foreigners it is lower than in the hosts, so it is necessary to investigate possible cultural factors that may influence hesitancy. A lower vaccination coverage in females, especially in foreigners, may be due to an inferior participation in social and working life as a consequence of the gender gap.

Key messages

• The creation of dedicated interventions guaranteed to achieve high vaccination coverage in all nationalities.

• A lower vaccination adherence in females than males, especially in foreigners, may be due to an inferior participation in social and working life as a consequence of the gender gap.

Estimated excess mortality figures in the year 2020-2021 in casentino municipalities (Italy)

Background

In 2020, the total deaths from all causes were the highest ever recorded in Italy since World War II (15.6% excess), with peaks during Sars-Cov2 waves and reductions in periods of national lockdown. On the contrary, in 2021, the total number of deaths from all causes reduced compared to the previous year. Analysing local mortality data, our study aims to assess whether, in the Casentino Valley (Arezzo, Tuscany), an excess of deaths from all causes occurred between January 2020 and December 2021 compared to the five years 2015-2019.

Methods

We used the official mortality data from the Italian Institute of Statistics (ISTAT), and that are published in the Table of deaths by the municipality on March 2, 2022. From this database, we extrapolated all deaths from all causes between January 1, 2020, and December 31, 2021, in the 10 municipalities of Casentino. The data collected were processed using Microsoft Excel 2016 software. We then distinguished by total per month, gender, and age group and then compared these data with the previous five years’ average by calculating the percentage change.

Results

Overall, both the years 2020 and 2021, it is shown an increase in the deaths percentages compared to the previous five-year period, respectively 5.66% and 8.07%. In particular, there is an excess of mortality in November and December 2020. The increase in mortality is more remarkable for males (13% in 2020 and 20% in 2021). The highest percentage increase was recorded in 2021 for the 75-84 age group (+15%) and in 2020 for males over 85 (+29%).

Conclusions

The data analysed confirms the excess mortality in 2020-2021 compared to the average of the previous 5 years in Casentino. There are peaks in November and December 2020, corresponding with the second wave of Sars Cov2 infection. The results obtained establish the basis for subsequent analyses that will verify the correlation of mortality peaks with the incidence of Sars-Cov2 cases in the territory studied.

Key messages

• Between January 1, 2020, and December 31, 2021 there was an excess of all-cause mortality in our area.

• This excess mortality appears to be related to peaks in Sars-Cov2 infection.

Patients’ migration for orthopaedic intensive rehabilitation among Italian Regions

Background

Interregional patients’ migration, according to Italian Law, can be considered an expression of the (inviolable?) right to health and freedom of choice regarding place of care. It contributing, albeit perversely, to guaranteeing equity in the Italian National Health Service allowing citizens to overcome territorial inequalities in the distribution of healthcare services. The aim of our study was to analyze fulfilment of needs for orthopaedic intensive rehabilitation hospital services on site and interregional patients’ migration trends.

Methods

We conducted an observational cross sectional study on Hospital Discharge Cards provided by the Ministry of Health, upon specific request, from 2011 to 2019. The study of interregional patients’ migration, for orthopaedic intensive rehabilitation, relative to single Italian regions was carried out from data of Residents, Attractions and Escapes, which were graphically developed through Gandy’s Nomogram. Trend analysis (Cuzick’s Test) was performed through STATA. Were considered statistically significant at level of 95% (p &lt; 0.05).

Results

In our studied period, Gandy’s Nomogram showed that only Piedmont, Lombardy, A.P. of Trento, E. Romagna, Umbria and Abruzzo had a good public hospital planning for orthopaedic intensive rehabilitation. Attractions increased significantly for Lombardy, A.P. of Trento, Veneto and Basilicata, while they decreased significantly for A.P. of Bolzano, Veneto, F.V. Giulia, Abruzzo, Calabria and Sicily. Escapes increased significantly for Veneto, F.V. Giulia, E. Romagna, Tuscany, Molise, Puglia and Basilicata, while they decreased significantly for Piedmont, Aosta Valley, A.P. of Trento, Umbria, Abruzzo and Sicily.

Conclusions

Only six regions (4 in the North, 1 in the Centre and 1 in the South) satisfied care needs of their Residents, with an Attractions minus Escapes positive balance. Only A.P. of Trento appears to have been able to reduce Escapes and increase Attractions at the same time.

Key messages

• Studying patients’ migration by type of health benefit makes it possible to identify specific situations of lack of supply.

• Patients’ migration is an indirect Index of a region’s health policy.

Which one to choose? A cost-effectiveness analysis between different technologies of air purifiers

Introduction

CoViD19 pandemic highlighted the importance of air purifiers and, in commercialization, their performance and price influence the choice. Since primary focus concerns only performance in terms of CADR (Clean Air Delivery Rate), this study aims to compare: I) levels of declared air purifications according to different types of air purification technologies; II) price of them to evaluate if, with similar group-mean CADR (within +/- 1 SD), there are significant differences in selling prices.

Methods

A review of several devices was carried out, collecting data in January-April 2022. Four different types of air purifiers were considered, divided into as many groups: those equipped with HEPA filters + UV lamps, only with HEPA filters, only with UV lamps and those using other technologies. We applied Kruskal-Wallis test to evaluate statistical differences among prices normalized by CADR, at significant level of 0.05.

Results

Analysis was carried out on 186 devices: I) 37 had HEPA filters + UV lamps, II) 117 only HEPA filters, III) 11 only UV lamps and IV) 21 other technologies. Eight system had HEPA H11 (95% reduction of particle matter 0.5 μm), 8 had HEPA H12 (99.5%), 70 had HEPA H13 (99.95%), 11 had HEPA H14 (99.995%). The mean normalized costs of each group devices, in Euros/CADR were I) 1.22 (SD 2), II) 1.49 (SD 1.4), III) 7.63 (SD 7.38), IV) 1.22 (SD 0.99), respectively. Statistical comparison of four-group selling prices show significant differences (p &lt; 0.05) due to the devices equipped with only UV lamps.

Conclusions

Comparison between technologies analyzed by mean price normalized to CADR showed significant differences between those that used only UV lamps compared to all the others. This is reasonably due to the fact that the use of only UV lamps requires radiant powers considerably greater than all the others, therefore also higher costs (about 5-6 times). In all cases, the level of disinfection reached, as declared, was always &gt; 95%.

Key messages

• With the same mean price normalized to CADR, the selling price is significanly different only for devices equipped with UV lamps compared to all the others.

• Choice of devices with a certain level of declared air purifications can be directed towards those with HEPA+UV/HEPA/other without the mean price normalized to CADR undergoing significant differences.

Invisible mother-daughter heredity

Background

The type of maternal caregiving impacts children’s growth and can lead to heritable changes in gene expression. When women become mothers, they adopt parents’ behaviours similar to those received in the family of origin. The study investigates if a birth’s social and cultural content can be seen as heredity transmitted from mother to daughter.

Materials and methods

A retrospective study was conducted on a group of mothers recruited across Italy through the social network Facebook. The study was carried out using a questionnaire administered from July to September 2021. The survey consisted of 21 questions. The analysis was carried out using STATA 14.

Results

Our sample consisted of 6051 mothers; the mean age was 37.7 years. Womens born by spontaneous birth has 2.1 times higher risk of having a spontaneous birth for their first child. Those born by operative labour have 2.7 times higher risk of having an operative delivery for their first child. Finally, those born by caesarean section are 2.3 times more likely to have a caesarean section for their first child. On the other hand, those born by preterm labour have 1.8 times higher risk of delivering their first child preterm. Those who were breastfed have 2 times higher risk of breastfeeding their first child. Women who have been told their birth is an extraordinary event are 2 times more likely to consider the birth of their first child as a problematic but still extraordinary event. Those who received a description of childbirth from their mother as a problematic event are twice as likely to consider the birth of their first child as a traumatic event overall.

Conclusions

The results show that transmission, written in the psyche, in preverbal and in internalisations derived from the relationship with one’s mother, is true and strongly present. Also, the ways of one’s own birth are so strong as to have repercussions on the daughter’s own and subsequently also on her children.

Key messages

• The unconscious objects, which are projected onto the children, can also take the form of both physical and psychic somatisations, which are repeated cyclically between generations.

• The way in which birth is cared for and the quality of care provided at this unique time in a woman’s life will leave an imprint not only on the woman herself, but also on future generations.

Stylish UV-C lamp for disinfecting household objects

Background

Considering the current pandemic situation, the growing problem of antibiotic resistance and the increase in healthcare costs, attention to daily disinfection is becoming increasingly important. This study aimed to evaluate the bactericidal efficacy of a modern and stylish UV-C device designed for the home environment.

Methods

The experimental study was conducted between July-August 2020 on four bacterial strains: Staphylococcus aureus, Salmonella typhymurium, Klebsiella pneumoniae and Escherichia coli. The UV-C device consist of a protective dome with a reflective coating, a UV-C lamp (placed in the device base) and three reflective holders. Different positions and exposure times were tested using two different carriers holder for the bacterial inoculum (plastic and stainless steel) to estimate the germicidal efficency related to UV-C lamp exposure, with direct and reflected (from the dome coating) light.

Results

The experiment showed that the higher bacterial inactivation effect (3.5 to 7 log10) was achieved for all four strains at 3 minutes, but even at 1 minute, there is a marked reduction in the bacterial load with the only exception of Klebsiella pneumoniae. After 45 and 30 seconds, steel carriers contaminated by Escherichia coli and Staphylococcus aureus on the opposite side of the UV-C source showed significant reductions in the range between 99 and 99,9%.

Conclusions

The device has proven to be effective for the disinfection of various everyday objects placed into the lamp and introduces beauty to the household environment.

Key messages

• In this study, UV-C device proved to be a valuable tool for disinfecting household items and enhancing safety for everyday health.

• UV-C device proved to be a valuable tool for disinfecting household items and enhancing safety for everyday health.

A novel technology for disinfecting surfaces infested with Candida auris: the UVC chip

Background

The fungal pathogen Candida Auris is increasingly associated with multidrug-resistant infections that are highly expensive for the Health Care System. The spreading of this pathogen can occur, among others, through contact with infected surfaces or medical instruments. This study evaluated the efficacy of a novel UVC chip, novel alternative to UVC LEDs and lamps, in inactivating Candida auris strain.

Methods

This experimental study was carried out between July and September 2020 at the University of Siena. Candida auris (ATCC 12372) at two known concentrations (1.5X107 and 1.5x106 CFU/ml) at a fixed distance (7,5 cm) from the chip (5.1mW radiant power) was tested, in triplicates, with three exposure times (5, 10 and 15 minutes). Potato Dextrose Agar (PDA) plates without the plate lid and containing Candida auris were exposed to UVC light. Subsequently, the plates were incubated at 36 °C for 48 h. Log reduction between treated and positive control (not exposed to UVC light) samples was calculated.

Results

At 15 minutes, we had the highest inactivation result, mean 4.43 log10, starting from a 1.5x106 CFU/mL concentration. At a higher concentration, 1.5X107 CFU/mL, the reduction had a mean of 3.51 log10.

Conclusions

The results of the experiments showed a significant microbial reduction in relation to the exposure time. The highest level of reduction was reached after 15 minutes of exposure. UVC chip had a relevant biocidal effect on Candida auris and may represent a valuable tool in the prevention of infections caused by this pathogen, which is becoming increasingly prevalent and persistent globally.

Key messages

• The use of UVC Chip decreases surface contamination.

• New technology against healthcare-associated infections.

Improving the quality of medical records

Background

Medical record is an essential tool both in patients’ diagnostic and therapeutic pathways and communication between different care providers. It also has an economic-administrative, medical-legal and epidemiological function. From an economic-administrative point of view, a medical record allows an evaluation and review of services to better manage the corporate health budget. In addition, it allows traceability and complete transparency of the health activities carried out. The study evaluates the formal quality of medical records compiled in an Italian private clinic before and after a training intervention.

Methods

In June 2019, a retrospective study was carried out to assess a private clinic’s quality of medical records. One month later, healthcare providers were trained on the appropriate compilation of medical records, whose pre-printed format was structurally improved. In March 2020, we verified the quality of medical records produced after that training intervention. Statistical analysis (Wilcoxon test) was carried out through Stata.

Results

A total of 149 medical records were reviewed. Statistically significant improvements (p &lt; 0,05), between before and after training intervention, were for overall readability (33.3% vs 74.7%), completeness of admission and discharge dates (33.3% vs 74.40%), for completeness of anamnesis (13.6% vs 63.9%), for completeness of therapeutic card (53% vs 85.5%), in the reduction of non-compliance corrections (22.7% vs 4.8%), signature presence of physical examination (34.9% vs 71.1%) and for signature presence in the hospital discharge card (86.4% vs 96.4%).

Conclusions

The results show that simple measures, such as staff training and restructuring of the format, are effective in improving the quality of medical records.

Key messages

• Healthcare providers should perceive the proper completion of medical records as a common goal.

• Well-completed medical records contribute to better health care.

Air purifiers, comparison between real and declared surface for use: fake it or make it?

Introduction

Air pollution has been recognized as one of the major risk factors for the global burden of disease. In modern society, most exposure occurs indoors, and air quality may be improved with air purifiers utilizing various cleaning techniques. This analysis aims to evaluate whether recommended room surface in which to use these devices as declared by producers is actually in line with their real effective area of activity.

Methods

A review of devices for the purification of the air was carried out between January-April 2022. Four different types of air purifiers were considered based on the adopted technologies: I) HEPA filters and UV lamps; II) only with HEPA filters; III) only UV lamps and IV) those using other technologies. For each group, based on the CADR (Clean Air Delivery Rate) provided by the producers, the optimal real surface area of the room to use the device was calculated, referring to the standard EN779:2012. This value was compared with the recommended area of the room declared by the producers. Descriptive statistics and Wilcoxon matched pair test used for comparisons. The significance level was set at p &lt; 0.05.

Results

The analysis was carried out on 252 devices; I) 52 had HEPA filters + UV lamps, with a recommended mean room area of 40 m2 (IQR 49.75), II) 142 devices had only HEPA filters with 52.5 m2 (IQR 46.75), III) 27 devices only UV lamps, 40 m2 (IQR 105), IV) 31 devices with other technologies, 54 m2 (IQR 84.2). As required by EN779:2012, the effective area of activity was calculated using CADR x 0.075: the medians of the 4 groups were I) 12 m2 (IQR 16.5), II) 15.83 m2 (IQR 26.4), III) 4.5 m2 (IQR 22.5), IV) 7.5 m2 (IQR 21.53), respectively. Comparing declared and calculated CADR values, all the groups showed significant differences (p &lt; 0.05).

Conclusions

Results show that recommended surfaces derived from CADR declared by producers largely overestimate the real volume of the room that devices can purify, whatever the technology used.

Key messages

• There’s no correspondence between recommended area of room to be sanitized indicated by producers of air purifiers and area that they are actually able to sanitize, which is significantly lower.

• It is necessary to be aware of the difference between data indicated by producers and real data, in order to purchase a device that actually corresponds to dimensional needs of the environment itself.

Flu and Covid-19: is there adherence to vaccination in target groups?

Background

In Italy, the flu vaccine is recommended and free for target groups (adults≥60 years old, fragile people, healthcare workers, pregnant women). During the 2020/2021 flu season, an increased vaccination coverage (+6,9%) was observed compared to the previous season, also due to the Covid-19 pandemic. We aimed to investigate how strong the adherence to the flu vaccine was by the vulnerable groups and assess if the Covid-19 vaccination campaign may have influenced the rate of flu vaccines.

Methods

At the beginning of autumn 2021 we conducted an online survey among the population of Tuscany. We collected data on demographics, health status (pregnancy, vulnerable), flu and COVID-19 vaccinations coverage and health information sources. In addition, we performed a descriptive and a risk factors analysis to assess correlation between our variables with R v 4.0.0. Significance level was set at p < 0.05.

Results

Among 408 participants, 248 (61%) belong to a vulnerable group and are recommended to receive the flu vaccine, 229 (56%) usually get the flu vaccine, 386 (95%) got the Covid-19 vaccine, 267 (65%) choose and trust the general practitioner (GP) as their health information source. There is a statistically significant association between being part of a vulnerable group and getting the seasonal flu vaccine (OR 6.63 95% CI 4.26-10.3 p < 0.001). In addition, getting the Covid-19 vaccine increases the likelihood of receiving the flu vaccine (2.90 95% CI 1.16-7.28 p = 0.018). Moreover, participants who trust their GP as their health information source (OR 1.63 CI 1.08-2.46 p = 0.019) are more likely to receive the flu vaccine; other information sources (TV, newspaper, social media) are not associated with the flu vaccine.

Conclusions

Our research shows that vulnerable groups get vaccinated against the flu. The increase in flu vaccine coverage may be due to the COVID-19 vaccines campaign. GPs play a crucial role in the health promotion, prevention and health literacy of patients.

Impact of lockdown on football players’ injuries

Background

The global outbreak of COVID-19 has resulted in the closure of stadiums and the interruption of Serie A for three months. Many studies have evaluated the effects of COVID on population health, but few have evaluated the effects of containment measures on the health of football players. With this study, we evaluated the impact of this break on Serie A football players.

Methods

This cross-sectional study was conducted considering a timespan of three Serie A seasons (2018-19; 2019-20; 2020-21). The information was obtained from the German website Transfermarkt. All the players who had played at least one match during each of the Serie A season were identified. For each of the players, data concerning the number of days lost due to injury, both before and after the stop in the championship due to Covid, were collected. Statistical analysis was performed using Stata 17 Software.

Results

According to the selection criteria, 264 players were selected. This group was subsequently skimmed to 256 players after eliminating all players who did not suffer physical injuries over the timespan considered (non-purely orthopedic surgery; COVID; Intestinal problems; Infections). 256 players were analysed, 228 had skipped at least one day for pre-lockdown due to physical injury (median=37,5), while 227 missed a day for post-lockdown (median=27). Wilcoxon signed-rank test between days lost due to injuries before and after lockdown highlighted significant differences (p < 0.05).

Conclusions

Comparing pre-lockdown and post-lockdown periods, we noticed that there were fewer days skipped due to physical injury post lockdown. Statistical evidence suggests that the same players were more susceptible to suffer physical injuries in the pre-lockdown period. This is probably because some players have worked with home coaching by spending more time in the gym and less time on the field. Also tapis roulant and cyclettes were often delivered to football players’ homes.

What kind of patient benefits the most from an intensive physiotherapy after total hip replacement?

Background

Hip replacement is a common orthopaedic surgery procedure that produces great improvement in the quality of life. Despite this, a globally standardized post-operative physiotherapy protocol still does not exist. The aim of this study is to identify the factors that influence the motor and functional outcome after early, intensive, hospitalized treatment.

Methods

A retrospective study was conducted in 2019 on 509 patients admitted to an Italian private clinic specialized in post-surgery rehabilitation, which applies an original bio-psycho-social-environmental protocol and individual rehabilitation plans. Data regarding each patient were collected from medical records: age, haemoglobin, Body Mass Index (BMI), Cumulative Illness Rating Scale (CIRS), Tinetti scale (TS) and Barthel scale (BS) at admission and discharge. The outcome was measured as the difference (Δ) between the values at discharge and admission of BS (ΔBS) and TS (ΔTS). We performed a univariate linear regression using STATA, to determine which factors influence the outcome. A p &lt; 0.05 was considered statistically significant.

Results

Our sample (57.4% female) was 70.1 ± 10.4 years old. ΔBS was significantly influenced by motor performance at admission (BS: Coef. - 0.708, CI 95% [- 0.743 - - 0.673]; TS: Coef. - 1.697, CI 95% [- 1.849 - - 1.544]), global health conditions (CIRS Severity index: Coef. 4.925, CI 95% [1.037 - 8.814]) and age (Coef. 0.312, CI 95% [0.221 - 0,403]). ΔTS was significantly influenced by the same factors, BS: Coef. - 0.167, CI 95% [- 0.184 - - 0.149]; TS: Coef. - 0.667, CI 95% [- 0.703 - - 0.631]; CIRS Severity index: Coef. 1.254, CI 95% [0.012 - 2.511]; age: Coef. 0.090, CI 95% [0.061 - 0.120]. BMI and haemoglobin did not influence the studied outcomes.

Conclusions

Patients with worse health conditions, advanced age and lower motor performance at admission obtain a higher outcome.

Key messages

• A broader knowledge of rehabilitation influencing factors would provide higher outcomes.

• The diffusion of individual rehabilitation plans would allow the achievement of better results.

A time-varying SIRD model for dynamic vaccination strategies against COVID-19

Introduction

The COVID-19 pandemic has demonstrated how the optimal allocation of the limited doses of vaccine available represents one of the main useful measures to mitigate the transmission of the infection and reduce the mortality associated with it, especially at an early stage of the pandemic. The use of a compartmental model allows us to understand which population groups to vaccinate and to what extent to act depending on the type of health or social objective to be achieved.

Methods

A time-varying susceptible-infected-recovered-deceased (SIRD) compartmental model, stratified into ten age groups, was developed on Italian data. Simulations were performed every 15 days from December 2020 to April 2021. An optimal vaccination strategy was achieved by minimizing deaths or infected, considering the total vaccine doses available.

Results

We showed how the effects of a vaccination campaign can be planned in a way that maximizes lives saved and/or minimizes infections. Regarding the minimization of deaths, the model prioritizes the elderly (&gt;80 years) and then those between 60 and 80 years, in all simulations. Regarding the cost function of new infections, the first simulation assigns all available doses to those over 90 years of age. In the later simulations, the doses are assigned mainly to the 20-29-year-old and the 89+ year old.

Conclusions

Optimal allocation of available vaccine doses is useful in mitigating transmission of infection and reducing mortality. Application of the mathematical model can be useful at the beginning of an epidemic caused by a new pathogen, when data are scarce, and it is therefore necessary to introduce a standardized approach. This kind of simulation is useful to understand whether the implemented vaccination strategy needs to be recalibrated, too.

Key messages

• Time-varying compartmentalised models can be used both to continuously inform decision-makers about changes in epidemic traits and to simulate the effects of targeted pandemic containment strategies.

• The application of compartmental models can be very useful at the onset of an epidemic to more successfully contain it and structure the health, political, and economic plan.

Improvement and standardization of disinfection in Hospital Theatre with UV-C technology

BACKGROUND

The level of disinfection between operating sessions is important to prevent cross-contamination risk in Operating Theatres (OTs). The aim was to assess the difference in microbial contamination between different disinfection levels (DLs), before T(0) and after T(1) application of a UVC Device (UVC-D).

METHODS

A cross-sectional study was conducted between December 2019 and August 2020 in a Clinic. Three DLs: no disinfection after surgery (DL0), after in-between cleaning (DL1), and after terminal cleaning (DL2), were compared to assess the reduction of microbial presence before T(0) and after T(1), the use of UVC-D that was used for 5-3 minutes per bedside. 260 Petri dishes (PD), divided into a preliminary phase followed by a probabilistic model-driven experiment, were used in 3 OTs, and Colony Forming Units (CFU) were counted. The Mann-Whitney test was performed in the preliminary phase to establish UVC exposure time. Using the probabilistic model, we calculated descriptive statistics and % and log₁₀ reduction. The MANOVA analysis for repeated measure was performed to verify the 95% statistical difference between T(0) and T(1), combined with the DLs and different OTs.

RESULTS

The Mann-Whitney showed no CFU difference between 3-5 minutes of UVC exposure time; the MANOVA test for showed no significant difference between DLs in T(0)-T(1) CFU reduction with a mean CFU reduction of 72% (CI95% 61.7 - 84.9%) regardless of the DL applied before.

CONCLUSION

UVC-D enhanced environmental disinfection under any initial conditions. In concert with sainting procedures improves and standardizes the level of environmental hygiene.

When childbirth turns red: the post-partum hemorrhagic emergency

Background

WHO affirms that post-partum haemorrhage (PPH) is the leading cause of maternal mortality and morbidity worldwide. The first step to recognize, prevent and diagnose this complication is to define it. The aim of this work is to identify risk factors for PPH.

Methods

A case-control study was conducted at the Hospital of Siena (Italy), including all females who have given birth from 2016 to 2018. In relation to presence of PPH (blood loss of ≥ 500 ml), the sample was divided into two groups. Analyzed variables were: age, parity, use of epidural, stimulation of labour with oxytocin or prostaglandins, episiotomy, manual removal of the retained placenta, medically assisted procreation (MAP), fetal weight, pre-pregnancy BMI (body mass index), placental localization and gestational age (GA). Statistical analysis was carried out using Stata 14.

Results

The sample was composed of 1490 women: 56% nulliparas, 18% had epidural, 34% had broken membranes, 22.6% had stimulation of labour, 1.5% had MAP. 8% older than 40 years, 32% of babies were ≥3500g; 5.1% had BMI ≥30; 11.2% had episiotomy; 2% had manual removal of the retained placenta, 3% had lateral placenta, 47.5% had GA ≥ 40th weeks. PPH occured in 15%; mostly in nulliparas (17.7% vs.12.4% p &lt; 0.01), those that used epidural (20% vs. 14.5%¸ p &lt; 0.05), MAP (32% vs.15.2%; p &lt; 0.05), those had manual removal placenta (71.9% vs.14.4%, p &lt; 0.05)in mothers of babies ≥3500g (21% vs. 13%; p &lt; 0.05), in those with BMI ≥30 (27% vs. 15%; p &lt; 0.05), those with lateral placenta (26% vs. 12.3%; p &lt; 0.05), and GA ≥ 40th weeks (17.3% vs. 13.6%; p &lt; 0.05).

Conclusions

PPH is one of the most studied obstetric emergencies being the leading cause of maternal mortality in the world. It is important to closely monitor during labour and childbirth to modify risk factors where possible.

Key messages

Postpartum bleeding is an obstetric emergency that causes mortality and morbidity in pregnant women. There are no effective treatments yet, so it is important to recognise the associated risk factors and prevent them.

'Wherever you are, my son, wait for me.' study on medically assisted reproduction

Introduction

In Italy the use of Medically Assisted Procreation (MAP) is increasingly frequent also because the mean age at which Italian women have their first child has increased in recent decades (31.8 years in 2017) and it is more difficult to have a child for an older woman. The aim of this study was evaluate the maternal and neonatal outcomes of MAP and compare them with those of natural pregnancies.

Methods

The cross-sectional study was performed during the period January 2015-June 2019. All women that gave birth in the Hospital of Siena were included. The sample was divided in two groups (Natural pregnancy/MAP Pregnancy). The outcome variables were: maternal age, number of foetus, type of childbirth, timing of the birth, Apgar Index and necessity of hospitalization in neonatal intensive therapy unit (NITU) or resuscitation. The statistical analysis was performed with Stata 12.

Results

In total 5066 females were included (4.5% MAP pregnancy). The average age (±SD) of females was 32,9±5,56 (min 14-max 61). The mean age (±SD) of women with PMA was significantly higher 38.7 ± 5.7 vs. 32.6± 5.4 of those who had natural pregnancy. In PMA Pregnancy there was a higher probability of multiple pregnancy (OR = 16.13; 95% CI 10.38-25.07; p &lt; 0.001), Caesarean Section (OR:4,54; 95% CI 3.28-6.31; p &lt; 0,001) and preterm birth (OR 3.79; 95% IC 2.80-5.14; p &lt; 0.001). Apgar index at the first minute was significantly lower in children born from pregnancies from MAP (8,6 ±1,4 vs, 9 ±1,4 p &lt; 0.01), the difference was significant even in the 5th minute (9,6 ±0,7 vs. 9,8 ±0,6 p &lt; 0.01). Children born by MAP Pregnancy had higher probability of hospitalization in Neonatal Intensive Care (OR = 3.12; 95% CI 2.12-4.59; p &lt; 0.001).

Conclusions

In our sample we found that MAP is used by women with older average age and it is associated with less favourable maternal and neonatal outcomes than those from natural conception.

Key messages

In Italy the use of Medically Assisted Procreation (MAP) is increasingly frequent because it is more difficult to have a child for an older woman. In our sample we found that MAP is used by women with older average age and it is associated with less favourable maternal and neonatal outcomes than those from natural conception.

An age grouped time-varying compartmental model for CoViD-19 vaccination strategy

Background

Compartmental models are the simplest in the mathematical study of infectious disease dynamics. Using an age-stratified compartmental model allows us to understand which population groups to target and to what extent to act, in order to achieve predefined goals in line with policy and/or health choices. In fact, the vaccination strategies of most countries are age dependent. With this study we want to show that the optimal vaccination strategy should be different depending on the type of health or social objective to be achieved.

Methods

A time varying susceptible-infected-recovered-deceased (SIRD) compartmental models, stratified into ten age groups of ten years was developed on Italian data. An optimal vaccination strategy was obtained minimizing deaths or infectious starting from April 11, 2021, considering the total doses due to Italy by the European contract for each type of vaccine from April to June. The efficacy of each vaccine and the days between administration and the beginning of immunization were also considered.

Results

On April 11, about 75% of over-80 Italian population have received at least the first dose of vaccine. Concerning the minimization of death, the model gives the priority to the older people (>60-year-old). This confirms the Italian vaccination strategy by completing the remaining vaccinations of over-80s and then vaccinating those between 60 and 80. Instead, if the priority were to reduce the infected, the model would recommend vaccinating the most of over-80s and the classes aged 20-30 and 40-60.

Conclusions

In conclusion, the use of this model can help to vary vaccine strategies by adopting targeted approaches to effectively achieve specific objective. For example, given the different age destination of some vaccine types, a good vaccination strategy might have been to vaccinate the over 90s with one type of vaccine to protect them from high risk of death while simultaneously vaccinating younger people to contain the spread.

Key messages

The modelling approach is an excellent decision support tool for pandemic containment.

The compartmentalized model stratified by age allows to act more efficiently on subpopulations.

An emerging innovative UV disinfection technology: virucide activity on SARS-CoV-2

Background

Surface sanitation is one of the key points to reduce the risk of transmission both in healthcare and other public spaces. UV-C is already used in hospital and laboratory's disinfection procedure furthermore some recent studies show effectiveness on SARS-CoV-2. UV-C may be generated by Lamps and Light Emitting Diode, but novel sources are emerging. The aim of the study was to test a device having UV chips for inactivating SARS-CoV2.

Methods

The descriptive study was conducted in the period between June and July 2019, in laboratories of the University of Siena and of the scientific park of Toscana life sciences. The device, shaped in a rectangular box, contained six UV chips (10 mW each, with a peak at 264nm nm ranging from 260 to 350 nm) placed in the bottom. Central and short side long positions were tested expecting different dose levels. Each experiment was conducted in triplicate, with and without the device lid, at 3, 6 and 10 minutes. All repetitions were tested for SARS-CoV-2 having a virus suspension of 10^7.2.

Results

The zones with the higher value of irradiance (max 187.9 µW/cm2) were near the corners of the box, while the lowest (min 61.9 µW/cm2) near one of the long sides. The light distribution was almost symmetrical. The tests revealed a viral charge reduction from an initial concentration of virus suspension of 10^7.2 TCID50/mL, of more than 99.9% after 3 minutes of UV exposure; at 6 minutes, the minimum Log10 attenuation value was over 5 Log10(99,999%); the maximum detectable attenuation value of Log10 = 5.7 was measured at 10 minutes.

Conclusions

This device is the first one which introduces this novel UV chip source, similarly it is the first time it was tested against the SARS-CoV-2. Objects that need to be disinfected may benefit of such devices according a proper exposition time for homogeneous disinfections of the surfaces.

Key messages

Implementation of cleaning and disinfection devices has been shown to reduce Sars-cov-2 infection incidence. In the hospital sanitation field, but also in public places and homes, using viable alternatives as UV-C can contribute to the reduction of pandemic spread.

Hospital Patients’ migration among Italian Regions

Background

At the beginning of the 2000s the federalization of the Italian National Health Service gave to the Regions greater financial and political responsibility: 21 Regional Health Services were set up with administrative and planning independence. They are in a potential competitive regime, since the citizens are free to choose their place of treatment. The aim of our research was to analyze fulfillment of needs for hospital services on site and Patients' migration to hospitals of other Regions.

Methods

We conducted an observational cross sectional study on Hospital Discharge Cards provided by the Ministry of Health, upon specific request, from 2013 to 2017. The subjects of the analysis (catchment areas) were the hospital networks of Italian Regions. Interregional flows were carried out from data of Residents, Attractions and Escapes, which were developed through Attraction and Escape Indexes. Graphic representation was produced with Gandy's Nomogram.

Results

In the studied period, we observed an important decrease in hospitalizations and a simultaneous increase in interregional mobility. At the same time, admissions to hospital managed by Local Health Authorities and to Private Clinics increased. According to the Major Diagnostic Categories the main causes of hospitalizations in mobility were Musculoskeletal System And Connective Tissue Diseases (MDC 8), Cardiovascular System Diseases (MDC 5), Nervous System Diseases (MDC 1) and Digestive System Diseases (MDC 6). There were discrepancies between the Regions of Northern/Central Italy (higher Attraction Indexes) and Southern Italy (higher Escape Indexes). According to Gandy's Nomogram only nine Regions showed a good public hospital planning: Lombardy, A.P. of Bolzano, Veneto, Friuli V.G., E. Romagna, Tuscany, Umbria, Latium and Molise.

Conclusions

The North/Centre Regions have a public hospital planning able to be better to meet the care needs of their citizens and to attract Patients than the South ones.

Key messages

The study of Patients’ mobility is relevant in order to evaluate equity and quality of care provided by different Italian Regions. Patients' mobility has also an important economic implications.

Economic crisis, epidemiology and resilience in Italian Regions

Introduction

Avoidable Mortality is an indicator of the effectiveness of Health Services. We know that Gross Domestic Product (GDP) and other macroeconomic indicators are related to health indicators. The aim was to study the impact of economic indicators on Avoidable Mortality, in Italy, with attention to the periods following the economic crisis and COVID-19 epidemic.

Methods

GDP, Gini Coefficient (GC) and other economic and epidemiologic data were collected from the beginning of the Century up to the present from the Italian National Institute of Statistics database (ISTAT) and the Italian National Institute of Health (ISS). Mortality data (597 causes coded by ICD-9) was divided in Preventable, Amenable and Avoidable categories. Spearman's rank Correlation Coefficient was carried out with STATA software. The analysis was performed, also using JOINPOINT software, on the entire Italian territory and then specifically on the 20 Regions.

Results

GDP trend showed two decreasing phases occurred between 2008-2009 and 2012-2013. A negative correlation (p.<0.05) has been demonstrated in 7 Regions between GDP values and Avoidable Mortality, 5 Regions for Preventable and Amenable Mortality. GC showed a fluctuating but growing trend without any correlation with all categories of Avoidable Mortality. In 2020, after the start of the COVID-19 pandemic (in February 2020 in Italy), GDP and Employment Rate (ER) declined rapidly, but not always homogeneously.

Conclusions

The upward trend of the GC reflects an increase in inequality in the period following the economic crisis. GDP trend reflects the phases of the economic crisis impacting on epidemiological indicators with a latency of about 4 years. The negative correlation between GDP and Avoidable Mortality can not be observed in all Regions. This may be explained by heterogeneous administrative policies and different levels of resilience among Regions: another description of the “european microcosm” represented by Italy.

Key messages

The impact of the economic crisis on Avoidable Mortality has about 4 years of latency. COVID-19 pandemic has a faster impact on GDP and ER.

Italian Regions show different levels of resilience.

Food and lifestyle education in Tuscan schoolchildren: 2018-2019 follow-up of a long-term campaign

Background

Nutritional profile, physical activity level and sedentary behaviours, in preteen age, are determinants able to influence both short and long-term state of health, therefore succeeding in health education campaigns addressed to this age group is critical for the interested population. Is currently underway the multiannual follow-up of the Italian “sCOOL FOOD - Per un Futuro di tutto Rispetto” project of Monte dei Paschi Foundation of Siena, Tuscany, which offers year-round cycles of classes and workshops about the themes listed above. Our objective was to assess whether this intervention could significantly influence over time healthy, and unhealthy, behaviours of the participants.

Methods

We structured the follow-up as a prospective cohort study with one-group pretest-posttest design. We used the CAWI technique, building a questionnaire based on the Italian “OKkio alla Salute” survey, and collected data from the whole population of students enrolled in the project (in the school year 2018-2019 they were 3787, aged from 7 to 12) before and after the intervention. Afterwards, we conducted paired data analysis on the frequencies of specific behaviours.

Results

We analysed paired data from 310 respondents. Improvements were gained in: afternoon TV watching (OR 0.54; 0.34 - 0.84; p &lt; 0.01), consumption of sweet (OR 0.39; 0.16 - 0.88; p &lt; 0.05) and salty (0.42; 0.18 - 0.90; p &lt; 0.05) snacks, attitude to play outdoors after school (OR 2.6; 1.21 - 6.04; p &lt; 0.01), sedentary behaviour in leisure time (OR 0.27; 0.16 - 0.44; p &lt; 0.0001), mean weekly sport activity (+0.14 days; +0.02 - +0.27; p &lt; 0.05). No variable has deteriorated.

Conclusions

The improved compliance with healthy behaviours in the participants at this project suggests its viability as a health promotion campaign. Further parallel surveys on control groups are pending, in order to control potential confounders such as the seasonality of some habits and the awareness of the participants on the addressed subjects.

Key messages

A coordinated and cross-disciplinary food and lifestyle year-round education campaign at school can affect health determinants of children. School can correct unfavourable eating and lifestyle behaviours determined by family habits.

Surveillance for severe acute respiratory infections in the 2019/2020 season in Tuscany, Italy

Background

Influenza is a major public health burden. In Italy there were 7.6 million symptomatic case of influenza in the 2019/2020 influenza season. In Italy, the influenza season lasts from October to April of the following year. We analysed influenza A and B viruses from hospitalized patients with Severe Acute Respiratory Infections (SARI) to carry out epidemiological and virological surveillance.

Methods

68 oropharyngeal swabs were taken from the patients with SARI at Le Scotte University Hospital in Siena and they were given a questionnaire to record their underlying disease and vaccination status. Total RNA was extracted from the swabs by means of the QIAamp Viral RNA Mini kit and RT-PCR was carried out. After, biodirectional DNA sequencing reactions were performed. All statistical analyses were performed by means of GraphPad Prism 6 software.

Results

The median age of subject was 82 years and 52.9% were female. The subjects showed fever (89.7%), fatigue (77%), headache (47%), cough (75%), sore throat (70.5%), breathlessness (63.2%).We found that 20.5% of 68 subject were positive (13% for A H3N2 and 7% for A H1N1). Out of the 68 subject, 25% received seasonal influenza vaccination (91.6% trivalent vaccine and 8.4% quadrivalent vaccine). The most common underlying disease found in the positive subjects were cardiovascular diseases (50%), renal diseases (50%), lung diseases (42.8%), diabetes (35.7%), cancer (35%).

Conclusions

Epidemiological and virological surveillance remains an essential tool for monitoring virus circulation and possible mismatches with seasonal vaccine strains, and providing information that can be used to improve the composition of influenza vaccines. Our data support the importance of seasonal vaccination in subjects with chronic diseases to reduce hospitalisation and mortality.

Key messages

Virological surveillance is important for determining the spread of influenza viruses. Seasonal vaccination is considered as the most effective way to prevent influenza and its complications.

Efficacy of nearuv-a to inactive microbial growth

Background

Microbes are less able to develop resistance towards antimicrobial blue light (aBL), at 405nm, towards disinfectants/antibiotics. In addition, Near UV-A light (nUV) is less harmful to host cell compared to UV-C irradiation. This study aimed to assess the efficiency aBL in reducing microbial growth on surfaces.

Methods

This cross-sectional study, run between July-October 2020. Petri dishes were contaminated with P. Aeruginosa, E. Coli, S. Aureus, S. Typhimurium, K. Pneumoniae at a concentration of 1.5x104 CFU/mL and were placed at 2 and 3m of distances from the light source having an irradiance of 967,39 and 497,33 µW/cm2 for 12 hours. The air confined the room was sampled for two weeks with two air samplers (SAS), before and after the exposition to the nUV light source to estimate the reduction of the environmental microbial contamination. The analysis was conducted using Stata software. Final results were expressed as logarithmic reduction mean with 95% confidence interval.

Results

The highest microbial reduction was reached 2m directly under the light. Significant (p &lt; 0.05) log-reduction were achieved for S. Typhimurium, 2.93 (IC 2.44-3.40), K.Pneumoniae, 2.30 (IC 2.14-2.46), S.Aureus, 3.98 (IC 3.78-4.12), E.Coli, 3.83 (IC 3.17-4.50), P. Aeruginosa, 3.86 (IC 3.22-4.48). At 3m of distance from the light source, it was observed a significant logarithmic reduction for S. Aureus, 3.49 (IC 3.34-3.65), and P. Aeruginosa, 3.80 (IC 3.11-4.47). In the air tests, we observed a mean percentage microbial reduction of about 70% after 12 h of exposure to nUV light.

Conclusions

nUV has proven to contrast microbial growth on the plates. It is possible to implement this technology in the environment for controlling microbial presence in “ad hoc” scenario but also in common areas. Mitigating the energy, it is possible to use this technology in presence of persons.

Key messages

In this experimental study, nearUV-A has proven to be efficient to reduce the microbial growth and to disinfect air and surface. NearUV light (nUV) can be use as an innovative technology for decreasing bacterial contamination, also in presence of people.

How the health-related quality of life in geriatric patients is influenced?

Background

Health requires a multi-dimensional approach and not just a cure for illness. Health can be assessed from the point of view of the objective state, but also from its perception which influences the quality of life (QoL). Several tools have been used to measure QoL in many clinical contexts such as five-level EuroQol-5 dimension questionnaire (EQ-5D-5L). The aim of the study is to evaluate the perceived QoL in geriatric patients.

Methods

We conducted a cross-sectional study, using EQ-5D-5L from January to December 2019. EQ-5D-5L was self-administered to a sample of 187 geriatric patients from a private clinical (100 beds). We performed a descriptive and statistical analyses using the five dimensions: mobility (M), self-care (SC), usual activities (UA), pain/discomfort (PD), anxiety/depression (AD) in association with BMI, age, sex, length of stay (LoS). The analyses (Spearman correlation coefficient) was carried out with STATA software.

Results

In our sample the 66,8% was female, the mean age was 78,35 ±10,9, the LoS had an average of 22,37 ± 37,72. Only 170 patients responded to EQ-5D-5L. The mean score of the five dimension of EQ-5D-5L was 3 excepted for the AD that was 2. The mean of EQ index was 0.44 ± 0.29, and it is realted to LoS (p = 0,01; Rho=-0,18). Only UA was associated to BMI (p &lt; 0.05; Rho= -0,21). The age and LoS were associated to M, SC and UA (p &lt; 0,03 Rho&lt;0,25). The gender appeared related to the M (p &lt; 0,02) with a worse perception in the female.

Conclusions

Our sample perceived a low quality of life that appeared to be related to the length of stay. Among the 5 dimensions mobility, self-care and usual activities were more influenced by our variables. A higher BMI doesn't appear as a limit to the habitual daily activities.

Key messages

Health requires a multi-dimensional approach and not just a cure for illness beacause it could influence the quality of life. The length of the stay seems to condition the quality of life of patiens and also a higher BMI seems not impacted the habitual daily activities.

There is no planet B: masks UVC disinfection to rise to the environmental challenge during COVID-19

Background

Since the outbreak of Sars-CoV-2 public health measures have been adopted globally, most notably the use of face masks has become essential and often mandatory. As a result, about 3.4 billion single-use face masks are estimated to be discarded daily worldwide. Due to waste mismanagement, the COVID-19 pandemic is severely impacting the environment, the ecosystem and therefore human health. We aimed to assess if UV-C light is an efficient tool for proper mask disinfection, to guarantee their safe reuse and reduce their waste.

Methods

In October 2020 we conducted a cross sectional study on KN95 masks. Various operators wore the masks during their shift in the laboratory for 8, 16 and 24h. Contact plates were used to measure microbial contamination on both surfaces of the masks at time T(0). Then, masks were placed into a UV-C box (volume of 0.012 m3, 40 UVC LED at 270nm at 3mW) for a treatment of 3 minutes. We repeated the sampling at time T(1). We incubated all plates at 36 °C and read them after 48h. We performed descriptive and inferential (Wilcoxon matched pair test) analysis with Stata. Significance level was set at p < 0.05.

Results

We always observed greater contamination on internal surfaces than external ones. At T(0) the medians of CFU on samples of internal surface were 212.7 (CI 95% 0-480.2) at 8h, 311.7 (0-683.1) at 16h and 404.7 (0-736.1) at 24h; at T(1), CFU reduced (p < 0.05) and were respectively 3.2 (0-6.2), 2 (0-5.9) and 50.6 (0-164.7). At T(0) the medians of CFU on external surface were 23.7 (0-48.4), 53.2 (0-143) and 24.3 (0-71.8); at T(1) they respectively reduced (p < 0.05) to 8.7 (0-25.2), 18.2 (0-70), 2.3 (0-6.1).

Conclusions

Results showed that UV-C is effective in mask disinfection although an uncomplete abatement of the microbial load. It could be due to the limited UV-C dose or to its difficulty to penetrate among the meshes of the mask. Further investigation is needed to find a sustainable solution for mask use.

Key messages

UV-C seems a valid disinfection tool for used KN95 masks.

The development of strategies for proper disinfection of masks should be carried out to guarantee reusability and reduce waste production.

Carbapenem-resistant enterobacteriaceae: don’t trust your neighbour

Background

The spread of carbapenem-resistant enterobacteriaceae (CRE) outbreaks consists not only of germs producing KPC and OXA-48, endemic already, but also metallo-beta-lactamase such as NDM or VIM. In Tuscany, Italy, a multidisciplinary regional task force has extended, since NDM alert spread out, from 1st Oct 2019 the CRE screening programme, via molecular testing, to newly admitted patients in high risk settings (medical, intensive care, oncology, transplant, infectious diseases, cardiac surgery units) to fight cross-contamination. The aim of the study is to assess levels and types of CRE in an italian teaching hospital (615 beds) after the programme became effective.

Methods

The surveillance team began recording daily all the CRE positive cases, defined as laboratory confirmed colonizations/infections with CRE. Our retrospective, descriptive study covers the time span between 30th Sep - 16th Dec 2019. Cases were classified by infected apparatus and by resistance phenotype, and we calculated descriptive statistics.

Results

In total we identified 97 cases (male 60.82%, mean (+/-SD) age 71.58+/-17.34 years, 74.23% in medical wards); 5 patients had two body districts infected and 9 carried two different phenotypes. Out of 102 positive samples, 92.16% were bowel colonization, 1.96% BSI, 3.92% urinary and 1.96% respiratory. Among these, 21 were NDM (19.81%), 29 KPC (27.36%), 4 OXA-48 (3.77%), 52 VIM (49.06%). The most detected germ was Klebsiella pneumoniae (30.19%), followed by Escherichia coli (2.83%), Enterobacter cloacae (2.83%), Citrobacter freundii and braakii (2.83%), Klebsiella oxytoca (1.89%). 61 agents were unspecified (57.55%). Among the 21 NDM, 76.19% were K. pneumoniae, only one was a BSI.

Conclusions

CREs continue to be present despite constant surveillance. Although high levels of KPC-producing agents persist, the new spread of VIM phenotype is significant, highlighting, however, that the pathogen wasn't detected in over 50% of the samples.

Key messages

Despite increased surveillance, there is still a consistent portion of patients colonized with unidentified CRE. A surveillance mainly focused on NDM-producing CREs had incidentally highlighted an unexpected spread of VIM phenotype.

Promoting sport and physical activity in Italy: a cost-effectiveness analysis of seven innovative public health policies

BACKGROUND

Inactive lifestyles are a key risk factor underpinning the development of many chronic diseases, yet more than half of the Italian population does not meet WHO thresholds for at least moderate physical activity. This study aims to make the economic case to upscale investments in policy actions to promote exercise and physical activity.

STUDY DESIGN

Modelling-based cost-effectiveness analysis in Italy.

METHODS

The study assesses the impact on health and healthcare expenditure of seven public health policies to promote exercise and physical activity against a business as usual scenario. Assessed policies include: promotion of active transport, workplace sedentarily interventions, investments in sports and recreation, mass media campaigns, prescription of physical activity in primary care, school-based interventions and mobile apps.

RESULTS

Public policies to promote exercise have the potential to improve population health and produce savings in healthcare expenditure. Assessed policies can avoid hundreds of cases of cardiovascular diseases and diabetes per year and tens of cases of cancer resulting in gains in DALYs in the order of thousands per year. In the medium-term, the vast majority of policies show excellent cost-effectiveness ratio, below internationally recognized thresholds.

CONCLUSIONS

Investing in policies to promote active lifestyles is a good investment for Italy.

Can the timing of hospitalization influence the outcomes of childbirth?

Background

The timing of hospitalization of pregnant females could influence the outcomes of both mother and the baby. The aim of this study was to analyze impact of coming to hospital too early on outcomes of childbirth.

Methods

A cross-sectional study was conducted in the birth center of Siena University hospital (Italy), all women that gave birth between 2017 and 2019 were included. Examined variables were: age, parity, gestational age: GA(weeks), Bishop score at admission: BS (0-13; &gt;9 high possibility of spontaneous delivery), time to delivery:TTD (min), labor duration:LD (min), n°of interventions (induction, amniorhexis, augmentation):NI, type of birth (vaginal/caesarean section: CS/operational birth: OB), laceration, episiotomy, hematic loss: HL (ml), skin to skin:StS and initiation of breastfeeding: BR (yes/no). The females that came too early were identified if TTD &gt;75° percentile. Analysis was performed with Stata 12.

Results

A total of 758 females were analyzed (32.0±5.2years), 55.5% multiparous, average GA was 39.6±1weeks, average BS was 7.2±2.5; 63% had BS &lt;9. Average TTD was 376.7±318.5min; 23% came too early (TTD 865.6±244), more likely primiparous (OR 3.9) and those with higher GA (OR 1.2). A negative correlation between BS and TTD was observed (Rho=-0.6), females with BS &lt;9 had higher probability to have prolonged TTD (OR10.8). Ninety-three% had vaginal birth, 6%CS, 1%OB Average LD was 169.1±145 min, average NI was 0.64±0.93, 78% had lacerations, 7.2% episiotomy. Average HL was 299.3±282.7ml. Females with prolonged TTD had higher NI (1.2 ±1 vs 0.4±0.6), higher probability of CS (OR 3), OB (OR4.5) and episiotomy (OR3.6), lower probability of StS and BR (OR 0.9), prolonged LD (299±184 vs. 120±102) and major HL (347.2±301.8 vs 284.9±275.4).

Conclusions

Our study showed an association between too early arrival to hospital and adverse maternal and fetal outcomes in terms of higher use of medical interventions that can interfere with physiological processes.

Key messages

The risk of arriving too early in hospital for labor was higher in primiparous and in those with higher gestational age. The too early arrival in hospital for labor was associated within increased use of medical interventions, interfering with physiological processes.

Sliding doors: how their opening affects particulate matter levels?

Background

The operating theatres (OTs) have adequate conditions to perform safe operations and to prevent surgical site infections. Opening doors can compromise these situations. Measurement of particulate contamination is a key point to check the effectiveness of preventive measures in the OTs. We analysed how openings impact in different type of OTs.

Methods

Between January/February 2020 a transversal study was conducted in 5 different types of OTs in a university hospital. Two had laminar flows, with 55 and 60 air changes/h; three had turbulent flows: OT-A (18 air changes/h, with 4 inlets from the ceiling), OT-B (23 air changes/h and air flow from the ceiling plenum), OT-C (16 air changes/h, air flow directed from one wall to the opposite wall and the main door laterally to the flow). Particulate matter (PM) measurements were carried out in 7 different points in each OT, alternating two conditions: a) doors closed; b) opening/closing the main door twice per minute. For each spot, in each condition, we recorded for several minutes the following parameters: particles (0.3, 0.5, 1, 3, 5, 10µ), room temperature (Ta), Relative Humidity (Rh), airspeed (Va). Comparison with the Wilcoxon test were made using STATA 14.

Results

In laminar flow, classified with better ISO levels (4), opening and closing the door the PM, for any size, increased not significantly (p &gt; 0.05). The OTs with turbulent flows (ISO 5-6) had a higher particulate level than the laminar ones and greater variations with door openings. OT-A worsened significantly for all particles (p &lt; 0.05) closing/opening the door. In contrast, OT-B and OT-C had a significant reduction of PM (p &lt; 0.05). All 5 OTs had pressure falling to 0 at door opening; Ta, Rh and Va may be affected by different type air flows and design.

Conclusions

OTs parameters during door openings are influenced by different ventilation systems and room design. Laminar flows OTs are less affected, but innovative turbulent flows OTs can be just as effective.

Key messages

The operating rooms are affected by the door opening. Laminar flows operating rooms are less influenced by door openings than turbulent flows ones. Turbulent flow rooms have different performance depending on their construction characteristics.

The venom bites in pregnant women: systematic review

Background

The snakebite in pregnancy are rarely reported in literature; they cause mortality and morbidity, the symptoms may be many, such as circulatory collapse, respiratory failure, bleeding, renal failure. The antivenom is the standard treatment, but it can be a potential cause of anaphylaxis and serum diseases; its effects on the fetus are unknown, so doctors may hesitate to apply it. We conducted this study because there are many cases not described in the literature also in Italy. The aim of systematic review is to evaluate the outcomes of the bites for women and newborns and the antivenom treatments in pregnant women, to understand the best behaviour to adopt.

Methods

In January-February 2020, we searched studies in Medline using the key MeSH Terms “snake bites” and “pregnant woman”. We included all case-control studies and letter to editor in English.

Results

The research yielded 22 publications: after title, abstract and full text's analysis, 12 manuscripts were included in this review. The studies were conducted from 2006 to 2019 in Japan, Taiwan, India, Pakistan, Thailand, Burkina Faso, USA, Israel and included a total of 14 pregnant women (1-3 women per study). The mean age was 30.47± 7.34, the average of pregnancy week was 21.50±11.25, 93.33% of mothers was alive as well as 60% of fetuses. The antivenom was given in 66.67% of cases, of these, all mothers were alive and only four newborns were dead (the deaths in studies don't seem to be related to the use of antivenom).

Conclusions

Snakebite during pregnancy could lead to serious complications for mother and fetus. The use of antivenom does not appear to be related to fetal or maternal death, and it should always be species-specific for the type of snake, so as to reduce the risk of adverse effects caused by antivenom or its improper use. It is necessary to implement guidelines for the correct management of therapy and to ensure good maternal and fetal outcomes.

Key messages

It is important to diagnose snakebite in pregnant women quickly in order to begin supportive therapy and identify the species of snake for the administration of the correct antivenom. An improvement of the guidelines is needed for better management of therapy in pregnant women.

A simulation model of microbe overlapping for the correct estimation of UV-C device log-reduction

Background

Candida auris is an emerging pathogen responsible for several outbreaks within healthcare facilities. It can be found on hospital surfaces and patient care devices. UV- C sanitisation may constitute an effective adjunct to routine room cleaning to prevent the spreading of this yeast. Previous findings with this technology suggest to investigate different sources of variability in the study of the biocidal effect of UV devices on C. auris. In this study we develop a computer simulation of surface distribution of microorganisms on a stainless steel carrier, to optimize UV-device experiments.

Methods

Based on the literature about C. auris studies and its estimated average size (about 5 μm diameter), several Matlab simulations have been performed to include as many microorganisms as possible to be ideally placed on a 20 cm2 stainless steel support, avoiding cell overlapping. This was done in order to maximize the effectiveness of UV exposure.

Results

Two initial simulations were performed to evaluate a random arrangement of a very large number of microorganisms (8x107 CFU) on the steel support, widely overlapped. In this case, due to the poor UV-C penetrability, we would not exceed two log10 reduction. By randomly distributing 1x106 CFU, the probability of overlapping was about 1.3%, but even a partial overlap limits the log10 reduction. By randomly distributing 1x105 CFU, the overlaps were at least 10 times less likely.

Conclusions

The simulation results allowed us to evaluate the most appropriate microorganism distribution model able to optimize the biocidal effects of UV-C devices. The overlapping of microorganisms reduces UV-C penetrability. Our simulated study is consistent with literature results where we observed a lower log-reduction by increasing the concentration of microorganisms and therefore the probability of overlapping. The resulting model would simulate any log-reduction scenario, at any distance and any concentration, with and without overlapping.

Key messages

The complete or partial microorganism overlapping plays a relevant role in the outcome of UV-C biocidal experiments. To identify the exponential CFU reduction curve and estimate accurately the inactivation rate constant, simulated experiments should be performed to assess the real effectiveness of UV devices.

Factors associated to functional outcome after total hip and knee arthroplasty

Background

An individual rehabilitation plan should guarantee a personalized approach to each patient. Identifying patients at risk of slower progression could help to implement a targeted approach. Aim of this study was to analyse patients characteristics associated to worse Functional Outcome (FO).

Methods

A cross sectional study of patients after Total Hip Arthoplasty (THA) or Total Knee Artroplasty (TKA) recovered in a Rehabilitation Clinic from January 2017 to December 2018 was performed. Patients characteristic: Age, Gender, Body Mass Index (BMI), Pain at admission (expressed in Numeric Pain Rating Scale: NRS), Cumulative Illness Rating Scale (CIRS) and Length of Stay in surgical facility (SLOS). Outcome tested: Active Flexion (AF), Barthel index (BI), Tinetti scale (TS), Pain at Discharge (PD). Patients were divided into two groups in relation to the achievement of target values in eight day of rehabilitation (AF = 84°, BI = 90, TS = 19 and PD ≥ 5). Statistical analysis was realized using Stata12.

Results

In total 1857 patients, 58% females, 56% after THA. Average age was 70.5±10.4, higher for females (72±9.7 vs. 68.3±11), average BMI 27.2±4.3, average SLOS 5.2±2.8. Regarding AF: 48% did not reach target value (38%THA; 55%TKA), for THA more likely older (OR 1.01) and females (OR 1.5) and for both THA and TKA higher NRS (OR 1.2). As for the BI target value was not reached by 24% patients (24.4%THA; 23.4%TKA); more likely older patients (OR 1.05), females (THA OR 2.1; TKA OR1.5), those with higher NRS (OR 1.13) and higher SLOS (THA OR 1.16; TKA OR 1.14). As for TS, 7% did not reached target (6.5%THA; 6.8%TKA), association with age (TKA OR 1.08; THA OR 1.04) and for THA also with SLOS (OR 1.13), pain (OR 1.16) and female sex (OR 2.16) was observed. As for the PD 17% not reached target (9.78%THA; 25.59%TKA), for TKA an association with BMI was observed (OR 1.08).

Conclusions

Worse FO was associated to not modifiable variables as age and gender but also with NRS, BMI and SLOS.

Key messages

Analysing patients characteristics associated to worse Functional Outcome allow to identify patients at risk of slower progression. The aim is to implement a targeted and personalized approach. The worse FO was associated to not modifiable variables as age and sex but also to higher NRS, prolonged SLOS and high BMI. Those conclusions help to manage an Individual Rehabilitation plan.

Operating Rooms efficiency: leveraging data to improve management of elective surgery

Background

Careful scheduling of elective surgery Operating Rooms (ORs) is crucial for their efficient use, to avoid low/over utilization and staff overtime. Accurate estimation of procedures duration is essential to improve ORs scheduling. Therefore analysis of historical data about surgical times is fundamental to ORs management. We analyzed the effect, in a real setting, of an ORs scheduling model based on estimated optimum surgical time in improving ORs efficiency and decreasing the risk of overtime.

Methods

We studied all the 2014-2019 elective surgery sessions (3,758 sessions, 12,449 interventions) of a district general hospital in Siena's Province, Italy. The hospital had3 ORs open 5 days/week 08:00-14:00. Surgery specialties were general surgery, orthopedics, gynecology and urology. Based on a pilot study conducted in 2016, which estimated a 5 times greater risk of having an OR overtime for sessions with a surgical time (incision-suture)&gt;200 minutes, from 2017 all the ORs were scheduled using a maximum surgical time of 200 minutes calculated summing the mean surgical times for intervention and surgeon (obtained from 2014-2016 data). We carried out multivariate logistic regression to calculate the probability of ORs overtime (of 15 and 30 minutes) for the periods 2014-2016 and 2017-2019adjusting for raw ORs utilization.

Results

The 2017-2019 risk of an OR overtime of 15 minutes decreased by 25% compared to the 2014-2016 period (OR = 0.75, 95%CI=0.618-0.902, p = 0.003); the risk of a OR overtime of 30 minutes decreased by 33% (OR = 0.67, 95%CI= 0.543-0.831, p &lt; 0.001). Mean raw OR utilization increase from 62% to 66% (p &lt; 0.001). Mean number of interventions per surgery sessions increased from 3.1 to 3.5 (p &lt; 0.001).

Conclusions

This study has shown that an analysis of historical data and an estimate of the optimal surgical time per surgical session could be helpful to avoid both a low and excessive use of the ORs and therefore to increase the efficiency of the ORs.

Key messages

An accurate analysis of surgical procedures duration is crucial to optimize operating room utilization. A data-based approach can improve OR management efficiency without extra resources.

The impact of mortality for infectious diseases on life expectancy at birth in Tuscany, Italy

Introduction

The epidemiologic transition describes the reduction of mortality for infectious diseases (ID), followed by an increase in prevalence of non-communicable diseases. During recent years the situation has changed; an increase in mortality for sepsis was observed. Italy is amongst the countries with the highest prevalence of microorganisms resistant to antimicrobial therapy in Europe. The aim of the present work was to evaluate the impact of mortality for ID on life expectancy (LE) in the Tuscany region(Italy).

Methods

Mortality data relative to residents that died during the period 2000/2002- 2013/2015 were provided by the Tuscan Regional Mortality Registry. At first the analysis was performed for whole territory, then for geographic area (Nord-Est:NE, Centrum:C, South-East:SE). The analysis was realized with software Epidat,using the Pollard's method of decomposition of variations in LE for age and cause

of death.

Results

The overall gain in LE was 2.9 years for males and 2.6 years for females. The increase in mortality for ID was responsible for the loss of 0.11 years of LE for males vs. 0.16 years for females. The loss was observed in males aged 45-89, for females from 69 years onwards, with the highest loss between 79-89 years. After analysis for area, geographical differences emerged, for both males and females the highest loss of LE was observed for NE (-0.23 years vs.-0.19), followed by C (-0.15 years vs. -0.16) and SE (-0.12 vs. -0.11).

Conclusions

The result can be partially explained by the transition from ICD-9 to ICD-10 (in 2010), which improved the sensitivity of codification, but also by diffusion of pathogens resistant to antimicrobial therapy. The highest impact of ID was observed in elderly, probably due to the existence of predisposing clinical condition. The ID deserve major attention; the programmes of hospital infection control and antimicrobial stewardship have to be potentiated in order to contain the phenomenon.

Key messages

During the study period an increase in mortality for infectious diseases comported the loss in terms of LE years. The growing diffusion of microorganisms resistent to antimicrobial therapy could have contributed to the higher mortality rates observed during the last period.

Increasing efficiency for reducing elective surgery waiting times: a multi-interventions approach

Background

Elective surgery long waiting times are a common problem in publicly funded health systems. They have been tackled allocating additional resources or using existing resources more efficiently but results are patchy. We studied the effectiveness of a multi-interventions project based on the reorganization of existing capacity.

Methods

In a district general hospital (Siena's Province, Italy) with 150 beds, 4 elective surgery operating rooms (ORs) opened 6 hours/day 5 days/week (surgery specialties: general surgery, orthopedics, gynecology and urology) in October 2018 a project for reducing surgery waiting times was implemented based on 3 key points: i) separation of the Day Surgery (DS) flow from that of the ordinary activity; ii) increase of available operating time through reorganization of personnel: 30 additional hours/week were made available; iii) allocation of operating sessions flexibly in proportion to the waiting list: the made-available hours were redistributed through an algorithm able to estimate the optimal allocation of surgical time blocks to minimize the length of waiting lists, taking account of the interventions priority class. The waiting time of the out from 1/10/2019 to 31/12/2019 (N = 635) was compared with that of the interventions carried out from 1/10/2018 to 31/12/2018 (N = 634) using t-test.

Results

Waiting times for non-urgent cases (that can be operated beyond 30 days) were significantly reduced for all specialties (p &lt; 0.01) except urology. For general surgery, orthopedics and gynecology, DS interventions' mean waiting time decreases from 198 to 100 days (-50%) that one of ordinary interventions from 213 to 134 days (-37%). Waiting time for urgent cases (to be operated within 30 days) was also reduced.

Conclusions

A multi-interventions project based on using existing capacity (personnel and structures) more efficiently and improving planning methodologies resulted to be strongly effective in reducing waiting times for elective surgery.

Key messages

To effectively reduce surgical waiting times, a strategy is needed that involve the entire process: from surgical planning, to staff and structures organization. The flexible OR time allocation on the base of the waiting list is a key point to improve surgery planning and reduce waiting list.

How much general practitioners empathize with patients?

Introduction

Thanks to the privileged relationship that the general practitioner establishes with patients, he well knows their personal background and assesses the disorders as a whole, without focusing only on unique pathology. The aim of the work were: I) to assess the level of concordance between the health profile (HP) of the patient measured by the doctor and that measured by the patient, and II) to and assess which variables influence the perception.

Methods

A cross-sectional study was conducted between Aug 2019-Jan 2020 in a primary care setting. To assess health-related quality of life we administered the EuroQol 5d-5L to patients (EQ-p). Simultaneously, we asked the doctors to fill in the questionnaire 'from the patient's point of view' (EQ-d), also based on data collected in the computerized clinical diary. Data was collected anonymously and the statistical analysis was carried out using Stata 14 (Cohen's kappa; Fisher test).

Results

The sample consisted of 223 patients (46% men). The mean age was 56.5±19.6 (min 18-max95). The mean BMI was 25.5±5 (28% overweight; 18% obese). Significant differences by gender were found in Pain and Anxiety/Depression dimensions (44% of men had not pain vs 33% of women (p = 0.03) and 56% of men had no Anxiety/Depression vs 36% of women (p &lt; 0.01)). These differences were not detected by doctors; As regards the concordance between EQ-p and EQ-d, it was moderate for Mobility (k = 0.45; p &lt; 0.01) and Self-Care (k = 0.46; p &lt; 0.01). The agreement was fair for usual activities (k = 0.39; p &lt; 0.01) and it was poor for Pain/Discomfort (k = 0.14; p &lt; 0.01), Anxiety/Depression (K = 0.19; p &lt; 0.01) and EQ Index (k = 0.11 p &lt; 0.01).

Conclusions

Our analysis shows a greater concordance especially for the dimensions that appear more objective (Mobility and self-care) than the subjective ones (Pain, Anxiety). The physicians do not seem to take into account the differences in perception between men and women when they empathize with patients.

Key messages

The general practitioner knows the personal history of his patients and assesses the disorders as a whole, without focusing only on the specific pathology. In the exercise of the identification, he seems to understand mainly dimensions that appear more objective without grasping the differences in perception between men and women.

Every cockroach is beautilful to the eyes of his mother? Parent’s perception of child’s BMI

Background

Childhood obesity is becoming a social health problem in the western world and an important goal is to analyze and correct risk factors. Part of the problem could be determined by a different perception of the weight. We aim to determine the association between children's BMI and the parent's perception of their Health Status.

Methods

In October 2019 we conduced a cross sectional study in which a questionaire was administrated to the parents of primary and secondary schools children in South-East Tuscany, Italy. Eating habits, lifestyle and biometric data were collected from children and their parents. 4324 persons were included. We used Stata for descriptive and inferential analysis. Cohen's Kappa was used to find the correlation between variables.

Results

Analysis was carried out on 1421 complete questionnaires. We found that most of parents have a wrong perception of weight's children. 88.3% of parents who have obese children belive that his child is normal weight or only “a little overweight” and only 11.7% have a perception of their child's obesity. 67.6% of parents who have overweight children, belive that their child is normal weight. While among underweight children, 74.3% of parents belive that their child is normal weight. Cohen's kappa show poor agreement between real and perceived BMI (K = 0.26; p = 0.0001).

Conclusions

Our results show, among the overweight children, there is a misperception in the weight of the child by the parents, uniformly with the data present in the literature. Acquisition of healty behavior during childhood is extremely important for the state of health in adulthood and for avoiding the onset of associated diseases. Therefore, food education becomes a crucial objective for the future of our country: an essential goal is to create prevention programs addressed to children and parents to increase consciousness of the correct weight and the diseases that can result from bad nutrition.

Key messages

Many parents have a misperception of the weight of their children. It is crucial to educate parents to control their children's weight to avoid the onset of metabolic diseases. Increase consciousness in children and parents of the correct weight should become extremely important to avoid the onset of disease in adulthood.

Know your enemy, fight the outbreak: an Italian experience

Issue

The New Delhi-Enterobateriaceae producing metallo-beta-lactamase NDM, resistant to carbapenems, are responsible of hospital outbreaks. The European Centre for disease prevention and control has published a report about the NDM outbreaks in Italy. Knowledge and application of all types of precautions is necessary to obtain adequate control.

Description

Between June and August 2019 an outbreak of Klebsiella pneumoniae producing NDM-1 occurred in an acute cardiac surgery setting from medium to high intensity, in a third level-hospital in Italy. Every patient with at least one positive typing test for NDM in clinical specimens was defined as a case. The infection control team sought patient 0, reviewed patients' daily records and created a timeline to control movements, verifying risk factors and time to positivity. The correct application of isolation and standard precautions was assessed. Auditing and training sessions were carried out. Our aim is to verify if these actions sufficed to control and halt the outbreak.

Results

Fourteen cases were identified, mean age=66.28 (SD = 13.55), 71.43% of them had a previous negative test. Positivity was found in samples from 13 rectal swabs (prevalence 12.38%), 7 lung aspirates, 3 urine cultures, 2 blood cultures and 2 wound swabs. Eight patients were positive in multiple body districts, 5 have been admitted to the same hospital within the year before, 3 came from other hospitals. The patient 0 has been moved in from a medical ward. After auditing, a training class was given to healthcare staff. The class concerned NDM phenotype, hand hygiene, isolation and personal protective equipment, with further observation in wards. In the following three months no new cases were registered.

Lessons

A continuous high-level adherence to standard precautions and hand hygiene by healthcare staff should be supported by adequate training. This is confirmed to be a strong action to prevent or stop cross-contamination.

Key messages

Colonization of multiresistant germs in healthcare due to cross-contamination has to be tackled promptly. Auditing and training actions should be taken into serious account in order to ensure an effective reaction from healthcare staff.

Cardiotocography monitoration in antepartum care: analysis of controls

Introduction

WHO does not recommend the routine prenatal cardiotocography (CTG) during pregnancy to improve maternal and perinatal outcomes. Instead, Italian guidelines consider CTG after the 41st week of pregnancy to be useful. The aim of this work was to identify the variables associated with CTG performed before the 40th week.

Materials and Methods

A retrospective study was conducted at the Hospital of Siena (Italy), all females that accessed to CTG from 2016 to 2018 was included. The variables were: nationality, pregnancy associated pathology(PAP), gestational age(GA), parity, type of access (urgent/programmed), n° of accesses, active fetal movements (AFM), amniotic fluid index (AFI) and necessity of recovery. The statistical analysis was carried out using Stata 12.

Results

The women included were 4010, mean age was 32.8±5.6 years (75% Italian; 62.4% primiparous). A mean GA was 38 ± 3 weeks; 47.5% had one access, 27% two accesses, 14% three accesses. The 22% were urgent accesses, 11.5% had PAP (70% diabetes mellitus). The 58% showed up before the 40th week, the probability was higher for non-Italian women (OR 1.3), multiparous (OR 1.32), women with urgent access (OR 7.9) and women with PAP (OR 3.4). In 5.4% the CTG was altered, 23% had absent AFM and 2% had alterated AFI. Females that came before 40th week were more likely to have absent AFM (OR 4.5) and AFI (OR 2). The 3% needed an immediate hospitalization, mainly in non-Italian (OR 1.7), urgent accesses (OR 4.4), those that came before 40th week (OR 2.44), absent AFM (OR 21.8), and altered AFI (OR 15.8),

Conclusions

Our analysis shows the association between precocious access to CTG and urgent medical condition and PAP as expected, but also with other variable as parity and nationality. The low GA without an indication of high risk at the moment of the access suggests the possible overmedicalization of pregnancy. It seems useful to review clinical practices to ensure obstetric care close to best practice.

Key messages

As literature reports, to avoid overmedication of pregnancy cardiotocography should not be performed before the 41st week of pregnancy. In some situations the CTG is anticipated and for this reason it seems useful to review the clinical practices implemented in order to ensure obstetric care close to best practice.

The applicability of methods for assessing comorbidities: The Cumulative Illness Rating Scale (CIRS)

Introduction

It is essential to compare the results of medical care in patients suffering from multiple, and complex diseases. CIRS is a risk adjustment tool useful for assessing patients’ comorbidities although it needs to be used with precision following guidelines. The aim of this research is to assess whether organised seminars, planned to motivate the clinicians for correct data compilation, have an effect on the concordance of scores on the CIRS scores.

Methods

A prospective, pilot study started in November 2018 on a sample of 49 patients admitted to a private clinic between December 2018 and February 2019. In the context of a seminar, an Resident Physician in Public Health (RP), distributed and explained the CIRS guidelines to the clinicians. CIRS scores were then calculated by the ward physicians and compared with those of the RP who successively analysed the same medical records. The inter-rater agreement was calculated through Cohen’s kappa coefficient (κ), using Stata 14.2.

Results

Concordance was excellent or almost perfect or substantial for 8 out of 14 categories: heart disease (k = 0.82), genitourinary disease (k = 0.90) blood pressure category (p = 0.72), sense organs (k = 0.75), upper gastrointestinal system (k = 0.70), lower gastrointestinal system (k = 0.76), musculoskeletal system and skin (k = 0.66), central nervous system (k = 0.69), endocrine system and breast (k = 0.63) and psychiatric diseases (k = 0.63). The agreement was moderate for the respiratory system (k = 0.48) and for the liver (k = 0.57), and was fair for Severity Index, Comorbidity Index and the vascular system (k = 0.24, k = 0.38 and k = 0.28 respectively).No Concordance in renal diseases (k = 0.00).

Conclusions

Overall, the agreement of the scores between RP and clinicians was good, and it was possible to analyse the main weaknesses and difficulties of the clinicians. Subsequent seminars will be done to increase over time the concordance of the surveys.

Key messages

Organized seminars, planned to motivate clinicians to correctly compile the CIRS scores, were effective. The inter-rater agreement was good. Subsequent seminars will be done to increase over time the concordance of the surveys.

Breastfeeding and Birth mode: comparative analysis between elective and in-labor caesarean section

Introduction

Evidence in literature suggests that the outcomes of children born by in-labor non-emergency caesarean section (CS) are better if compared to those born by programmed CS. The aim of this work was to evaluate impact of type of CS on neonatal outcomes and breastfeeding.

Materials and methods

The cross-sectional study was performed in the Siena province (hospital of Siena and Poggibonsi) during the period January-December 2015. All females that gave birth by CS were included, except those that had emergency CS from severe medical indication (pre-eclampsia/eclampsia, fetal distress, intrauterine growth retardation, etc) or due to multiple pregnancy.

The sample was divided in two groups (programmed CS/CS in the presence of labor). The outcome variables were: necessity of hospitalization in neonatal intensive therapy unit (NITU) or resuscitation; weight loss after birth (%), hours passed between birth and first attack to the breast, type of breastfeeding at discharge (exclusive/mixed). The statistical analysis was performed with Stata 12.

Results

In total 446 females were included (53.6% programmed CS). Any association between the type of CS and admission to NITU or resuscitation was observed.

Among the newborns born by CS in the presence of labor, there was a greater proportion of babies who attached to the breast immediately after birth (82% vs. 71%; p &lt; 0.05) and also those exclusively breastfed at the moment of discharge (71% vs. 60%; p &lt; 0.05).

The weight loss was lower in babies born by CS in the presence of labor (8%±1.8; 95% CI 7.7%-8.2% vs. 8.53%±1.7%; 95% CI: 8.3%-8.8%; p &lt; 0.05).

Conclusions

Our study confirmed the negative impact of the CS in the absence of labor on the breastfeeding initiation, probably due to incomplete activation of neuroendocrine mechanisms (release of oxytocin; etc). The CS in the presence of labor is more stressful from the organizational point of view, but it helps promotion of health through the facilitation of breastfeeding.

Key messages

In-labor non-emergency caesarean section is more physiological and helps to initiate and maintain breastfeeding. The CS in the presence of labor is more stressful from the organizational point of view, but it helps promotion of health through the facilitation of breastfeeding.

Finding alternative roles for Traditional Birth Attendants: an experience from the south of Angola

Background

Reduction of maternal mortality ratio (MMR), a key indicator contained in the Sustainable Development Goals (SDGs), is strictly related to maternal empowerment and to an increasing access to skilled care in pregnancy, childbirth and postpartum. The WHO recommends to define alternative roles for Traditional Birth Attendants (TBAs) in the transition from birth with TBAs to birth with Skilled Birth Attendants (SBAs), in particular in countries where maternal care services still do not meet recommended standards.

Objectives

In 2018, the Italian Non-Governmental Organization Doctors with Africa CUAMM and the District Health Department of Ombadja (a 350000 inhabitants district in Cunene province, south of Angola) started a three-year multifaceted project to support and strengthen local health services. Aim of this work is to describe the first six months of an implemented activity involving 120 local TBAs, identified and trained to perform basic educational talks in the district territory regarding topical issues of mother and child health. TBAs were also engaged in the referral of pregnant women to health facilities with SBAs.

Results

From June to November 2018, TBAs performed 2272 talks about maternal and child health issues: healthy pregnancy (551 talks, 24.3%), nutrition (404, 17.8%) and malaria (370, 16.3%) were the most debated topics. The total of women’s presences during these educational talks was 57504, and 15379 of them (26.7%) were pregnant. TBAs referred to health facilities 226 pregnant women for a delivery assisted by SBAs.

Conclusions

Angolan estimated MMR in 2015 was 477/100000 live births: therefore, more efforts should be made to contribute to the achievement of 2030 SDGs target of 70/100000 globally. Moreover, the country percentage of deliveries assisted by SBAs is less than 50%. Promoting alternative roles for TBAs into the mother and child health framework could represent an effective way to improve maternal and neonatal outcomes.

Key messages

According to the World Health Organization, defining alternative roles for traditional birth attendants could represent an effective way to support the health of women and children. Traditional Birth Attendants can play an important role in providing basic health education and in the “referral chain” of pregnant women to health facilities with skilled birth attendants.

The decomposition of life expectancy for age and cause of death in Tuscany, Italy

Introduction

Changing of life expectancy at birth (LE) over time reflects variations of mortality rates of a certain population. Italy is amongst the countries with the highest LE, Tuscany ranks fifth at the national level. The aim of the present work was to evaluate the impact of various causes of death in different age groups on the change in LE in the Tuscany region (Italy) during period 1987-2015.

Material and methods

Mortality data relative to residents that died during the period between 1987/1989 and 2013/2015 were provided by the Tuscan Regional Mortality Registry. The causes of death taken into consideration were cardiovascular (CVS), respiratory (RESP) and infective (INF) diseases and cancer (TUM). The decomposition of LE gain was realized with software Epidat, using the Pollard’s method.

Results

The overall LE gain during the period between two three-years periods was 6.7 years for males, with a major gain between 65-89, and 4.5 years for females, mainly improved between 75-89, &lt;1 year for both sexes. The major gain (2.6 years) was attributable to the reduction of mortality for CVS, followed by TUM (1.76 in males and 0.83 in females) and RESP (0.4 in males; 0.1 in females). The major loss of years of LE was attributable to INF (-0.15 in females; -0.07 in males) and lung cancer in females (-0.13), for which the opposite result was observed for males (gain of 0.62 years of LE).

Conclusions

During the study period (1987-2015) the gain in LE was major for males. To the reduction of mortality for CVS have contributed to the tempestuous treatment of acute CVS events and secondary CVS prevention. For TUM the result is attributable to the adherence of population to oncologic screening programmes. The excess of mortality for INF that lead to the loss of LE can be attributed to the passage from ICD-9 to ICD-10 in 2003 (higher sensibility of ICD-10) and to the diffusion of multi-drug resistant bacteria, which lead to elevated mortality in these years.

Key messages

The gain in LE during the period the 1987-2015 was higher in males. The major contribution to gain in LE was due to a reduction of mortality for CVS diseases.
