Impact of antibiotic exposure on antibiotic-resistant Acinetobacter baumannii isolation in intensive care unit patients: a systematic review and meta-analysis

BACKGROUND

Acinetobacter baumannii (AB) poses a significant threat to critically ill patients in intensive care units (ICUs). Although an association between antibiotic exposure and resistant AB is reported in the literature, a synthesis of evidence in ICU patients is still lacking.

AIM

To summarize the evidence on the association between prior antibiotic exposure and the occurrence of resistant AB in ICU patients.

METHODS

Online databases were searched for cohort and case-control studies providing data on the association of interest. Carbapenem/multidrug-resistant AB isolation was compared with non-isolation; carbapenem/multidrug-resistant AB was compared with carbapenem/antibiotic-susceptible AB; and extensively drug-resistant AB isolation was compared with non-isolation. Each comparison was subjected to a restricted maximum likelihood random-effects meta-analysis per antibiotic class, estimating pooled ORs. Stratified meta-analyses were performed by study design, outcome type and association-measure adjustment.

FINDINGS

Overall, 25 high-quality studies were retrieved. Meta-analyses showed that carbapenem/multidrug-resistant AB isolation was associated with previous exposure to aminoglycosides, carbapenems, third-generation cephalosporines, glycylcyclines, and nitroimidazoles. Increased risk of isolation of carbapenem/multidrug-resistant AB isolation vs carbapenem/antibiotic-susceptible AB was shown for prior exposure to aminoglycosides, antipseudomonal penicillins, carbapenems, fluoroquinolones, glycopeptides, and penicillins. Third-generation cephalosporin exposure increased the risk of extensively drug-resistant AB isolation vs non-isolation.

CONCLUSION

This systematic review clarifies the role of antibiotic use in antibiotic-resistant AB spread in ICUs, although for some antibiotic classes the evidence is still uncertain due to the small number of adjusted analyses, methodological and reporting issues, and limited number of studies. Future studies need to be carried out with standardized methods and appropriate reporting of multivariable models.

Attitudes of university students towards mandatory COVID-19 vaccination: a cross-sectional survey

Background

Vaccination is an effective public health measure to control the COVID-19 pandemic. In Italy, vaccination against SARS-CoV-2 was made compulsory by law for some job categories, such as healthcare and education workers. Although students required a valid COVID-19 certificate to access university, they were never subjected to mandatory vaccination. In this context, we investigated their attitudes towards mandating COVID-19 vaccination to be able to access schools and universities.

Methods

We conducted a cross-sectional survey from September 2021 to February 2022. A multivariable logistic regression model was built to identify predictors of positive attitudes towards the outcome. Adjusted odds ratio (aOR) and 95% confidence intervals (CIs) were calculated.

Results

We collected 5287 questionnaires, grouped into three periods (September-October 2021, November-December 2021 and January-February 2022). The highest proportion of students supporting COVID-19 mandatory vaccination (62.5%) was found between November and December 2021. Multivariable analysis showed that November-December and January-February participants had higher odds of having a positive attitude towards the vaccine mandate than September-October respondents (aOR=1.26, 95% CI:1.09-1-48; and aOR=1.22, 95% CI:1.01-1.48). Other positive predictors were age (aOR=1.01, 95% CI:1.01-1.03), higher levels of perceived COVID-19 severity (aOR=1.09, 95% CI:1.05-1.14), concern for the emergency (aOR=1.09, 95% CI:1.05-1.14), getting vaccinated for fear of infecting other people or being infected (aOR=1.08, 95% CI:1.04-1.12; and aOR=1.07, 95% CI:1.03-1.10) and believing that vaccines could end the pandemic (aOR=1.49, 95% CI:1.41-1.56).

Conclusions

Attitudes towards COVID-19 mandatory vaccination changed over time, probably in relation to the pandemic trends. Moreover, feeling involved in the pandemic situation seems to be related with a positive attitude.

Key messages

• Pandemic trends may affect the attitude towards vaccine mandates. Mandating vaccines to access universities could be taken into account in emergency situations to ensure a safer learning environment.

• Involvement in the pandemic situation seems related with a supportive attitude towards vaccine mandates, suggesting that awareness is a key factor to be addressed to implement mandatory vaccination.

The role of health literacy in vaccination behaviours: a systematic review

Background

Health literacy (HL) is recognized as a driver of health-promoting behaviors, including preventive actions. However the influence of HL on vaccines uptake remains unclear. This study aimed at summarize the evidence on the role of HL in vaccination behaviors.

Methods

PubMed, Scopus, and Web of Science were searched. Observational studies of any design conducted worldwide, published through June 2021 and investigated the association between HL and vaccination intention or status using HL validated tools were included. Any vaccine was considered. An adapted Newcastle-Ottawa Scale was used to assess quality.

Results

Twenty-one articles were included, 6 investigated intention to vaccinate and 15 explored vaccination status. Studies of the first group had a cross-sectional design, considered anti-COVID-19 vaccination and were judged of high or fair quality. Population investigated was heterogeneous as well as the tool used to assess HL. Five analysis provided adjusted estimates. HL seemed not influence the vaccination intention in 3 studies whereas adequate HL was associated with positive attitude to get vaccinated in the remained 3 ones. The majority of articles assessed vaccine status, had a cross sectional design (N = 11) and were of high quality (N = 8). The HL tool more frequently used was TOFHLA (N = 5), sample investigated was heterogeneous included parents of children who received vaccinations (N = 5). Four articles considered multiple vaccinations, thus providing a total of 19 analysis. Vaccine against influenza was the most investigated (N = 11) and 15 studies provided adjusted estimates. No association was found between HL and the receipt of vaccination in 11 analysis, whereas HL levels significantly influenced vaccination uptake in 8 studies.

Conclusions

Health literacy did not seem to strongly influence people decision on vaccinations. Difference in population and vaccines considered, but also in tool used to measure HL might explain the heterogeneity of the results.

Key messages

• The impact of HL on vaccination behaviours remains controversial.

• Efforts to extend the studies on targeted populations applying a comprehensive HL measurement tool should be devised.

Risk factors for SARS-CoV-2 infection: a case-control study in college students after vaccination

Background

Within the SARS-CoV-2 screening campaign offered through RT-PCR test by Sapienza University of Rome, we conducted a case-control study to identify the risk factors for the acquisition of SARS-CoV-2 infection among university students.

Methods

Positive students identified through the SARS-CoV-2 screening campaign (September 2021 - February 2022) were enrolled as cases and matched to two randomly selected students who tested negative on the same day. The interview questionnaire consisted of 39 questions investigating exposure to modifiable and nonmodifiable risk factors for SARS-CoV-2 in the two weeks before testing. A multivariable conditional logistic regression model was constructed to identify predictors of SARS-CoV-2 infection. Adjusted odds ratio (aOR) and 95% CI were calculated.

Results

Out of 8.730 tests for SARS-CoV-2, 173 students tested positive (2.0%), of which 122 were included in the case-control study (response rate: 70.5%). Most students were female (73.2%), with a mean age of 23.3 years (SD ± 3.6), vaccinated for SARS-CoV-2 (97.8%) and enrolled in non-health faculty (56.8%). At the multivariable analysis, significant positive associations were found with having had contact with a person who tested positive for SARS-CoV-2 (aOR: 3.04, 95% CI: 1.59-5.82) or having been to a disco/nightclub (aOR: 5.37, 95% CI: 2.00-14.38). Instead, being vaccinated against SARS-CoV-2 (aOR: 0.13, 95% CI: 0.01-0.93), having a valid EU COVID digital certificate (aOR: 0.06, 95% CI: 0.01-0.30) and attending lectures in-person (aOR: 0.35, 95% CI: 0.17-0.70) were negatively predictors. No association was found for sex, age, health faculty students, use of public transportation, attendance at restaurants or gyms.

Conclusions

The results highlight how anti-COVID-19 vaccinations and the reasons for students to obtain an EU COVID digital certificate may prevent students from getting infected. In addition, university environment seems to be safe for students.

Key messages

• Promoting SARS-CoV-2 vaccination adherence in the college-age population is crucial to limiting the SARS-CoV-2 spread.

• Attending in-person educational activities in regulated settings (e.g., low occupancy, mask use) may not be a risk factor for COVID-19 infection.

Molecular characterization of A. baumanni isolates causing co-infections in SARS-COV-2 patients

Background

Respiratory viral infections, such as COVID-19, predispose patients to co-infections leading to increased morbidity and mortality. A. baumannii poses as a serious threat to hospital facilities because of its ability to persist in the environment and acquire multi-drug resistance. The aim of this study was to quantify the extent of A. baumannii cross-infection and identify any gene clonality between isolates in SARS-CoV-2 patients.

Methods

Bacterial isolates of A. baumannii found in patients with SARS-CoV-2 admitted to the main Intensive Care Unit (ICU) of the Umberto I Teaching Hospital of Rome were collected between March 2020 and February 2021. Isolates were typed by pulsed-field electrophoresis to analyse their homology relationships.

Results

Overall, 196 SARS-CoV-2 patients were admitted to the ICU. They were mainly male (N = 138) and aged 63 years on average. Of these, 122 died, and 74 were discharged. A total of 157 strains of A. baumannii were isolated from 74 patients (38%), who had a higher mean hospital stay than patients in whom the bacterial strain had not been isolated (24.6 vs. 12.2 days). The genotypic analysis of 120 isolates revealed two main patterns (A and F) and a few subtypes, especially A8 (43%), A4 (29%), and A11 (10%). Clone A8 was found mainly between October 2020 and February 2021, clone A4 in April-December 2020 and January-February 2021, and A11 in December 2020 and January 2021. The strains were susceptible to colistin only, were isolated mostly from tracheobronchial aspirates (41%) or rectal swabs (35%) and accounted for 56 healthcare-associated infections (33% of which sustained by A4, 38% by A8, and 9% by A11).

Conclusions

The isolation of A. baumannii from patients with COVID-19 highlighted the importance of monitoring co-infections caused by this pathogen, which frequently shows a multi-drug resistant profile that may lengthen the hospital stay. It is essential to implement preventive measures to contain these infections.

Key messages

A. baumanni is a pathogen that needs to be monitored because it may lengthen the hospital stay of SARS-CoV-2 patients. In critically ill patients, the continued growth of multidrug-resistant organisms shows the importance of preventing these infections.

Incidence rate of Healthcare Associated Infections in a COVID-19 Intensive Care Unit

Background

Intensive Care Units (ICU) faced a high pressure under the COVID-19 pandemic. It is recognized that patients admitted in these wards are more susceptible to Healthcare Associated Infections (HAIs). This study aims at comparing the incidence of HAIs in a COVID-19 ICU to a No-COVID ward.

Methods

A retrospective cohort study including patients admitted to the ICU of the Teaching Hospital Policlinico Umberto I in Rome from April 2020 to March 2021 was performed. Data on age, gender, hospitalization, different types of devices (ventilation, central venous and urinary catheter), number and type of device-related HAI were collected. Statistical analyses were performed with Episheet and STATA 13.

Results

Out of 347 patients admitted in the ICUs, 329 were included in the study (217 had COVID-19 and 112 had not). In the COVID-19 group, patients were mainly male (69.58%) with a mean age of 62.5±13.5 years, whereas the other group was slightly older (63.2±16.2 years) and more balanced between the two sexes (52.68% male). A total of 133 patients developed at least one HAI, 94 of which were SARS-CoV-2 positive. Globally, 246 HAIs were diagnosed: 163 occurred in the COVID group and 83 in the No-COVID one. The cumulative days of hospitalization were 3233 for the COVID group and 2134 for the No-COVID. The incidence of HAI considered for 1000 days of hospitalization among COVID patients was 50.42 (IC 95%: 42.97-58.78), compared to 38.89 (IC 95%: 30.98-48.22) for the No-COVID one, for an incidence rate ratio of 1.30 (IC 95%: 0.99-1.71).

Conclusions

Even though the confidence interval contains the value 1, the results point out that there is an increase in the incidence rate of HAI among COVID-19 patients. Further investigations are needed to better understand the reasons behind the present findings.

Key messages

Patients admitted to Intensive Care Units are more susceptible to Healthcare Associated Infections. Our study aims at describing the impact of COVID-19 on the risk of developing such conditions.

Being infected with COVID-19 leads to an increase in the incidence rate of Healthcare Associated Infections. Further studies are needed to understand the underlying reasons.

A dynamic GIS space-time diffusion model to tackle COVID-19 emergency

Background

Surveillance and containment of the spread of COVID-19 requires the use of advanced geographic information science and technology (GIS&T) to map the spread and eventually to guide interventions. A dynamic space-time diffusion model in a GIS environment was developed and succesfully tested in Rome, Italy.

Methods

Information on cases of SARS-CoV-2 infection confirmed by molecular diagnostics from Feb 25 to Sep 26 2020 (collected by a large Local Health Unit of Rome, Italy) was used to test a GIS simulator model able to monitor the spatial diffusion and temporal evolution of the spread of the disease. Data included information on: sex, date and place of birth, healthcare facility of hospitalization, date of notification, start date and end date of isolation, date of recovery (both clinical and laboratory confirmed), residence address.

Results

Globally, 3,056 cases were geocoded and analysed. The spatio-temporal analysis of the first 45 days since 25 Feb 2020 shows that the spread of COVID-19 was very fast (1,230 cases recorded on 11 Apr) and spatially widespread. Number of cases was highest in the city centre with clusters, thickets and axes in different sub-municipal areas. A slowdown occurred the following month, confirming the positive effect of the lockdown. This effect continued until 11 Jun with a small increase in the number of cases (+10.9%). The period up to 26 Sep is paradigmatic of the second wave, with a continuous increase in cases that spread from the city centre to the suburbs.

Conclusions

Using geocoding process and a detailed GIS mapping it is possible to identify streets, buildings and census sections where the number of cases is high and tends to increase rapidly and, at the same time, it is possible to distinguish clusters and axes that should be kept immediately under special observation as potential pools of super-diffusion. Development of its use in near-real time could bring significant advantages in controlling the spread of COVID-19.

Key messages

The use of GIS technology is fundamental for mapping the spread of COVID-19.

A greater effort should be made by institutions to increase the digitisation of health data and the possibility of using them for both research and surveillance purposes.

COVID-19 vaccine hesitancy among university students: how worrying is it? An Italian survey

Background

With the availability of COVID-19 vaccines, vaccine hesitancy (VH) poses a great challenge to achieving herd immunity. Since young adults are usually asymptomatic, they may be less inclined to follow social distancing and mask-wearing guidelines. This study aimed at (i) quantifying VH among university students and (ii) investigating its determinants to identify barriers and predisposing factors to COVID-19 vaccination.

Methods

Students physically attending Sapienza University of Rome during April 2021 were invited to take part in an online survey. The questionnaire explored sociodemographic variables, COVID-19 experience, attitude towards preventive measures, and COVID-19 vaccination. Hesitancy was measured as the complement to 10 of students' intention to get vaccinated and was modeled through zero-inflated negative binomial regression analysis.

Results

Overall, 1949 students were surveyed. Most were females (59.9%) and aged 23.8±4.9 years on average. A great proportion reported no (76.8%) or slight hesitancy (15.7%). At multivariable analysis, in the count part, being more scared for the pandemic (IRR=0.94, 95%CI: 0.89-0.98), rating COVID-19 as more severe (IRR=0.93, 95%CI: 0.89-0.98) and being Italian rather than non-Italian (IRR=0.68, 95%CI: 0.54-0.85) were associated with lower VH, but no influence was found for age, sex, self-perceived risk of infection, and being a medical student. In the logit part, rating the vaccines as safe (b: 0.92, 95%CI: 0.75-1.10) or effective (b: 0.30, 95%CI: 0.14-0.45) decreased the likelihood of being hesitant.

Conclusions

A few factors seemed to influence the intention to get vaccinated against COVID-19, including vaccine safety and effectiveness. Hence, attention should be given to planning effective communication about the vaccine profile in order to maintain and improve the public's confidence. Also, partnerships should be established among the stakeholders to ensure coordinated information sharing and dissemination.

Key messages

Almost one-quarter of the surveyed students reported VH to some extent, and a few factors seemed to play a role in the vaccination decision-making process. Among others, the perceived vaccine safety and effectiveness seemed to influence VH. Attention should be given to planning effective communication about the vaccines’ profile.

The other side of COVID-19: a cross-sectional study on mental health in a sample of Italian nurses

Background

The COVID-19 pandemic and the resulting drastic increase in the workload for healthcare professionals, particularly nurses, has had serious consequences on the psychological well-being of these professionals. Our study aimed at (i) identifying demographic, work-related factors, and clinical predictors of Post-traumatic stress disorder (PTSD) and Generalized Anxiety Disorder (GAD) in nurses employed during COVID-19 pandemic and (ii) assessing problem-focused coping strategies implemented by nurses.

Methods

We carried out a cross-sectional study between December 2020 and April 2021, addressed to nurses employed during the COVID-19 second wave (October - December 2020). PTSD and GAD were assessed by Social Readjustment Rating Scale, Impact of Event Scale - Revised (IES-R) and General Anxiety Disorder -7 scale.

Results

Overall, 359 nurses were included in the study, whose mean age was 31.75 years (SD ± 9.77). Most were female (80.8%), unmarried (53.2%) and employed in the central (52.5%) and northern (36.4%) regions of Italy. A total of 59.7% of all participants had clinical predictors of PTSD, recording a mean score of IES-R of 38.2, SD ± 19.2, range 1- 84 (cut-off >33 for PTSD). Furthermore, 45.6% of respondents reported moderate - severe symptoms consistent with generalized anxiety disorder. Statistical significance was found between GAD and nurses being employed on the front line (Intensive care unit and emergency department) during the COVID-19 second wave (p = 0.016), and between GAD and clinical predictors of PTSD (p = 0.001). Furthermore, we found a statistically significant association between PTSD and nurses who were employed in hospitals or institutions dedicated to COVID-19 (p = 0.028).

Conclusions

PTSD and GAD represent a public health problem to be addressed in the post-pandemic period. Healthcare organizations need to activate specific support and rehabilitation networks and programs for healthcare professionals employed during the COVID-19 pandemic.

Key messages

The levels of PTSD symptoms and anxiety among nurses were high during the pandemic.

It is necessary for health systems to differentiate between temporary and long-term mental disorders in order to provide the health workforce with appropriate rehabilitation.

Impact of the Covid-19 pandemic on health services utilization: a cross-sectional study

Background

Health services disruption during the COVID-19 pandemic has forced to postpone or cancel most scheduled health visits. Within this context, disadvantaged people may have been suffered the most from the indirect consequences of the emergency. The aim of the study was to quantify the pandemic impact on health services utilization in the Roman population based on the economic, sociodemographic and cultural characteristics.

Methods

In January 2021, an online survey was administrated to 640 patients attending a Roman general practitioner. The questionnaire investigated sociodemographic characteristics, working and living conditions, COVID-19 experience, consequences of lockdown or policy responses, and health literacy. A multiple logistic regression model was built to investigate factor associated with a reduction in the healthcare use.

Results

Overall, 451 respondents were surveyed. More than 60% were women and mean age was 55 years. In total, 211 patients referred to have cancelled one or more scheduled health visits (14 vaccinations, 60 screening exams, 168 medical examinations and 23 surgeries). At multivariable logistic regression analysis, the loss of at least one visit seemed to be associated with lower perceived wealth (aOR=1.60, 95%CI: 1.07-2.39), pre-existing comorbidities (aOR=1.60, 95%CI: 1.04-2.45), and older age (aOR=1.03, 95%CI: 1.01-1.04). No association was found for sex, education, or health literacy.

Conclusions

A few socio-demographic characteristics seemed to identify people that may have suffered the most from the health services disruption during the COVID-19 pandemic, contributing to worsen the existing health inequalities. Future research is needed to devise strategies aimed at containing the negative effects of the pandemic on vulnerable populations.

Key messages

The COVID-19 pandemic seemed to have a greater impact on health service utilization among disadvantaged people. The COVID-19 pandemic may have exacerbated health inequalities.

Mapping levels of COVID-19 vaccine hesitancy worldwide: preliminary results of a systematic review

Background

Several factors can determine the success of a vaccination campaign, regardless of the availability of an effective and safe vaccine. Among these, vaccine hesitancy (VH) has long represented one of the main barriers to achieving vaccination coverage goals in many countries. The aim of this systematic review was to summarize the global levels of COVID-19 VH and to identify their determinants.

Methods

A systematic review of the literature was carried out following the PRISMA guideline and searching on PubMed, Web of Science, Scopus and PsycINFO for observational studies published up to April 2021 in English or Italian language. Levels of hesitancy and data on determinants, according to the SAGE working group matrix of determinants, were extracted. The systematic review protocol was registered on Prospero (ID: CRD42021235328).

Results

Of the 5447 articles initially retrieved, 89 were included in the qualitative synthesis. The included studies investigated COVID-19 VH on 1.954.331 individuals from 68 different countries (North America 19; South America 23; Africa 3; Asia 18; Europe 55; Oceania 4) between March 2020 and January 2021. Rates of hesitancy, before to the worldwide availability of vaccinations (82 studies), ranged from 84.6% (Cameroon, May-August 2020) to 10.37% (China, March-June 2020). Studies carried out on January 2021 (N = 7) showed rates ranging from 42.8% (Turkey) to 5.3% (UK). A subgroup analysis of data referring to healthcare workers showed the highest hesitancy rates in Honk Kong (60%) and Turkey (26.6%), before and after vaccine availability, respectively.

Conclusions

Preliminary results confirm the wide variability of VH across the world. The ongoing quantitative synthesis on prevalence of VH and the analysis on determinants will allow to update intervention strategies to address VH, both in general population and healthcare workers, orienting public health policies.

Key messages

Vaccine Hesitancy continues to be one of the greatest threats to global health and, in the long term, one of the potential barriers to the success of the global COVID-19 vaccination campaign. Identifying and synthesizing the specific determinants of COVID-19 vaccine hesitancy is essential to guide intervention strategies to promote vaccine confidence and, finally, vaccine acceptance.

The impact of the COVID-19 pandemic on healthcare-associated infections in intensive care unit patients: a retrospective cohort study

Background

During the intensive care units’ (ICUs) reorganization that was forced by the COVID-19 emergency, attention to traditional infection control measures may have been reduced. Nevertheless, evidence on the effect of the COVID-19 pandemic on healthcare-associated infections (HAIs) is still limited and mixed. In this study, we estimated the pandemic impact on HAI incidence and investigated the HAI type occurring in COVID-19 patients.

Methods

Patients admitted to the main ICU of the Umberto I teaching hospital of Rome from March 1st and April 4th 2020 were compared with patients hospitalized in 2019. We assessed the association of risk factors and time-to-first event through multivariable Fine and Grey’s regression models, that consider the competitive risk of death on the development of HAI (Model 1) or device related-HAI (dr-HAI, Model 2) and provide estimates of the sub-distribution hazard ratio (SHR) and its associated confidence interval (CI). A subgroup analysis was performed on the 2020 cohort.

Results

Data from 104 patients were retrieved. Overall, 59 HAIs were recorded, 32 of which occurred in the COVID-19 group. Patients admitted in 2020 were found to be positively associated with both HAI and dr-HAI onset (SHR: 2.66, 95% CI 1.31–5.38, and SHR: 10.0, 95% CI 1.84–54.41, respectively). Despite being not confirmed at the multivariable analysis, a greater proportion of dr-HAIs seemed to occur in COVID-19 patients, especially ventilator-associated pneumonia, and catheter-related urinary tract infections.

Conclusions

We observed an increase in the incidence of patients with HAIs, especially dr-HAIs, mainly sustained by COVID-19 patients. A greater susceptibility of these patients to device-related infections was hypothesized, but further studies are needed.

What is the Prevalence of Low Health Literacy in European Union Member States? A Systematic Review and Meta-analysis

BACKGROUND

Many studies have shown that low health literacy (HL) is associated with several adverse outcomes. In this study, we systematically reviewed the prevalence of low HL in Europe.

METHODS

PubMed, Embase, and Scopus were searched. Cross-sectional studies conducted in the European Union (EU), published from 2000, investigating the prevalence of low HL in adults using a reliable tool, were included. Quality was assessed with the Newcastle-Ottawa Scale. Inverse-variance random effects methods were used to produce pooled prevalence estimates. A meta-regression analysis was performed to assess the association between low HL and the characteristics of the studies.

RESULTS

The pooled prevalence of low HL ranged from of 27% (95% CI: 18-38%) to 48% (95% CI: 41-55%), depending on the literacy assessment method applied. Southern, Western, and Eastern EU countries had lower HL compared to northern Europe (β: 0.87, 95% CI: 0.40-1.35; β: 0.59, 95% CI: 0.25-0.93; and β: 0.72, 95% CI: 0.06-1.37, respectively). The assessment method significantly influenced the pooled estimate: compared to word recognition items, using self-reported comprehensions items (β: 0.61, 95% CI: 0.15-1.08), reading or numeracy comprehensions items (β: 0.77, 95% CI: 0.24-1.31), or a mixed method (β: 0.66, 95% CI: 0.01-1.33) found higher rates of low HL. Refugees had the lowest HL (β: 1.59, 95% CI: 0.26-2.92). Finally, lower quality studies reported higher rates of low HL (β: 0.56, 95% CI: 0.06-1.07).

DISCUSSION

We found that low HL is a public health challenge throughout Europe, where one in every three to almost one in every two Europeans may not be able to understand essential health-related material. Additional research is needed to investigate the underlying causes and to develop remedies.

Association between non-adequate health literacy and cancer screening adherence: a meta-analysis

Objective

Individuals with non-adequate health literacy (NAHL) are more likely to have poor health outcomes and behaviors, including a limited use of preventive services. This study aimed at summarizing the evidence on the association between NAHL and adherence to cancer screening programs.

Methods

PubMed, Scopus, and Web of Science were searched. Cross-sectional studies conducted in any country, published through January 2020 and quantifying the association between NAHL and cancer screening adherence, were included. An adapted Newcastle-Ottawa Scale was used to assess quality. Inverse-variance random-effects methods were used to produce pooled estimates: overall, by cancer and by HL tool.

Results

Seventeen articles of heterogeneous quality were included in the systematic review and 45 analyses were combined. NAHL was found to negatively influence screening adherence in both the crude (n = 26) and adjusted (n = 19) pooled analyses, and the association was slightly stronger in the latter (OR = 0.70, 95%CI: 0.62-0.79 and aOR=0.66, 95%CI: 0.57-0.76, respectively). Moreover, NAHL was significantly associated with lower adherence in all the types of cancer screening investigated: breast cancer (n = 7), aOR=0.55, 95%CI: 0.38-0.78; cervical cancer (n = 4), aOR=0.63, 95%CI: 0.53-0.75; prostate cancer (n = 1), aOR=0.60, 95%CI: 0.36-0.99, and colorectal cancer (n = 7), aOR=0.85, 95%CI: 0.74-0.97. Lastly, tools measuring NAHL with reading comprehension/numeracy items yielded the strongest association with the outcome (n = 5, aOR= 0.53, 95%CI: 0.35-0.80), that was attenuated in tools with either self-reported comprehension items (n = 7, aOR=0.72, 95%CI: 0.65-0.80) or medical term recognition items (n = 7, aOR=0.74, 95%CI: 0.57-0.95).

Conclusions

This study shows that NAHL may have a significant impact on adherence in all types of screening programs analysed, independently of the tools applied to measure it. Hence, it should be a useful focus for interventions to improve screening participation rates.

Key messages

Non-adequate health literacy negatively influences cancer screening adherence. Efforts to promote the uptake of cancer screening programs should consider and address NAHL.

A new gaming platform to improve cognitive performance and promote healthy behavior: a pilot study

Background

Brain training games can sharpen the mind and potentially prevent cognitive diseases, that are particularly relevant to the population ageing. The EU funded project ACDC, Adult Cognitive Decline Conscientiousness, developed an online training tool to train cognitive functions and promote healthy behaviors in the adult population.

Methods

An online platform, consisting of 16 games with different levels, was built. Three main brain domains were targeted: memory, visuospatial and verbal skill. After the completion of each game level, healthy lifestyle tips were presented to the users. Participants were actively recruited from the project partners; inclusion criteria were adult age (40-70 years) without cognitive diseases. An adapted version of the Montreal Cognitive Assessment was used to assess cognitive performance at the start and after two hours of active gaming. The paired t-test was used to compare the scores before and after the training. A satisfaction questionnaire was administered at the end of the training session.

Results

Fifty-six participants from three European countries (Austria, Spain and Italy) took part in the pilot phase (median age: 57, IQR: 47-66). Most of them were university graduates (38%) or had a high school diploma (41%), employed full-time (46%) and females (82%). Significant improvements were registered in the verbal domain, where the mean score increased from 4.18 to 4.83 (p = 0.047), and in the memory area, where the mean score grew from 4.80 to 6.60 (p < 0.001). The visuospatial mean score improved from 4.55 to 5.16 (p = 0.0518). Most users (84%) were greatly satisfied with the platform and reported a high level of appreciation for the interactive gaming approach.

Conclusions

Despite the small sample size, the pilot phase detected some improvements in cognitive performance and a good appreciation of the training tool. Given these encouraging findings, the study will now be extended to more participants.

Key messages

The newly developed platform represented a promising tool to train cognitive functions. The proposed interactive gaming approach was greatly appreciated by the users.

Predictors of Healthcare Associated Infections and Their Role on Mortality in an Intensive Care Unit

Background

Healthcare associated Infections (HAIs) represent a significant burden in terms of mortality, morbidity, length of stay and costs for patients in intensive care units (ICUs). In this study, we analyzed the predictors of HAIs development and assessed the HAIs association with mortality. Data were retrieved from a general ICU active surveillance system of a large teaching hospital in Rome.

Methods

Logistic regression models were built to quantify the association between demographic and clinical factors and the development of HAIs, device-related HAIs and Multi Drug Resistant (MDR)-associated HAIs. The HAIs independent predictors were used to create propensity scores (PS) specific for each model, that was subsequently used to adjust the association between these conditions and mortality in logistic regression models.

Results

From May 2016 to September 2019, 864 patients were included in the surveillance system, 236 (27.3%) of which had at least one HAI during their hospitalization. Specifically, 162 (18.8%) patients had at least a device-related HAI and the overall mortality rate was 34.3%. Factors associated with the HAIs and the device-related HAIs were mechanical ventilation and admission for trauma. The PS-adjusted logistic models showed an association between HAI and device-related HAI and mortality (OR 1.82, 95%CI 1.30-2.54; OR 2.03, 95%CI 1.40-2.95, respectively). MDR-associated HAIs had a significant association with diabetes mellitus; however, these infections weren't associated with mortality (OR 1.42, 95%CI 0.98-2.08), even in the subgroup of infected patients (OR 0.99, 95%CI 0.56-1.73).

Conclusions

The study confirms the association between HAIs and device-related HAIs with mortality in ICUs. Apparently, MDR-associated infection subset appears not having a specific association with mortality. However, given the extra effort that these infections require to be managed, they should be adequately surveilled and contrasted.

Key messages

Healthcare associated infections are strongly associated with mortality in ICU. MDR-associated infections do not seem to give a specific drawback in our setting.

Multimodal surveillance of healthcare associated infections in an intensive care unit of a large teaching hospital

BACKGROUND

Healthcare-associated infections (HAIs), or nosocomial infections, represent a significant burden in terms of mortality, morbidity, length of stay and costs for patients hospitalized in intensive care units (ICUs). Surveillance systems are recommended by national and international institutions to gather data on HAIs in order to develop and evaluate interventions that reduce the risk of HAIs.

STUDY DESIGN

Here we describe the methodology and the results of the surveillance system implemented in the ICU of the Policlinico Umberto I, a large teaching hospital in Rome, from April 2016 to October 2018.

METHODS

The multimodal infection surveillance system integrates four different approaches: i) active surveillance of inpatients; ii) environmental microbiological surveillance; iii) surveillance of isolated microorganisms; and iv) behavioral surveillance of healthcare personnel. Data were collected on catheter-related bloodstream infections, ventilation-associated pneumonia, catheter-associated urinary tract infections and primary bloodstream infections that developed in patients after 48 h in the ICU. For environmental surveillance 14 points were selected for sampling (i.e. bed edges, medication carts, PC keyboards, sink faucets). The system of active surveillance of HAIs also included surveillance of microorganisms, consisting of the molecular genotyping of bacterial isolates by pulsed-field gel electrophoresis (PFGE). From 1 November 2016, monitoring of compliance with guidelines for hand hygiene (HH) and proper glove or gown use by healthcare personnel was included in the surveillance system. After the first six months (baseline phase), a multimodal intervention to improve adherence to guidelines by healthcare personnel was conducted with the ICU staff.

RESULTS

Overall, 773 patients were included in the active surveillance. The overall incidence rate of device-related HAIs was 14.1 (95% CI: 12.2-16.3) per 1000 patient-days. The monthly device-related HAI incident rate showed a decreasing trend over time, with peaks of incidence becoming progressively lower. The most common bacterial isolates were Klebsiella pneumoniae (20.7%), Acinetobacter baumannii (17.2%), Pseudomonas aeruginosa (13.4%) and Staphylococcus aureus (5.4%). Acinetobacter baumannii and Klebsiella pneumoniae showed the highest proportion of isolates with a multidrug-resistant profile. A total of 819 environmental samples were collected, from which 305 bacterial isolates were retrieved. The most frequent bacterial isolates were Acinetobacter baumannii (27.2%), Staphylococcus aureus (12.1%), Enterococcus faecalis (11.1%), Klebsiella pneumoniae (5.2%) and Pseudomonas aeruginosa (4.7%). All Acinetobacter baumannii, Pseudomonas aeruginosa and Klebsiella pneumoniae environmental isolates were at least multidrug-resistant. Genotyping showed a limited number of major PFGE patterns for both clinical and environmental isolates of Klebsiella pneumoniae and Acinetobacter baumannii. Behavioral compliance rates significantly improved from baseline to post-intervention phase.

CONCLUSIONS

By integrating information gathered from active surveillance, environmental microbiological surveillance, surveillance of bacterial isolates and behavioral surveillance of healthcare personnel, the multimodal infection surveillance system returned a precise and detailed view of the infectious risk and microbial ecology of the ICU.

Prevalence survey of healthcare-associated infections in a large teaching hospital

BACKGROUND

Healthcare-associated infection (HAI) is the most frequent adverse event in healthcare settings. It is associated with increased mortality and antimicrobial resistance, leading to prolonged hospital stays and consistent financial loss for healthcare systems. The objective of this study was to estimate the burden of HAIs and antimicrobial use in the Teaching Hospital Policlinico Umberto I (THPUI) of Rome and to identify the most critical areas for intervention.

METHODS

Data were collected according to the most recent ECDC point prevalence survey protocol in November 2018. Descriptive statistics for all variables were calculated. Univariate analysis was used to assess possible associations between variables and HAIs. Variables with a significance level of p<0.25 were included in a multiple logistic regression model.

RESULTS

A total of 799 patients were included in the analysis; of these, 13.3% presented with at least one HAI. Bloodstream infection was the most common, accounting for 30.9% of total infections. Overall, 125 microorganisms were isolated, with Enterobacteriaceae being the most frequent (32%). At the time of the survey, 49.1% patients were receiving antimicrobial therapy. The multivariate analysis showed a significant association between HAI and use of medical devices (OR=34.30; 95% CI:3.69-318.66), length of stay (OR=1.01; 95% CI:1.00-1.02) and exposure to prophylactic antimicrobial therapy (OR=0.23; 95% CI:0.11-0.47).

CONCLUSIONS

The ECDC methodology proved to be applicable to THPUI, where HAI prevalence was higher than the European standard (6.7%). This highlights the need to implement targeted measures to prevent and control HAIs, including continuous monitoring to evaluate the effectiveness of such interventions.

Can nurses improve self-management among pediatric patients? A systematic review and meta-analysis

Background

Few studies report educational interventions for pediatric patients with asthma or diabetes type 1 as a fundamental instrument to engage them and improve their health. The aim of this systematic review and meta-analysis was to synthesize evidence about behavioral changes in life style, disease management and clinical outcome in pediatric patients after a structured educational intervention delivered by nurses.

Methods

A systematic review of the literature was carried out in MEDLINE, Scopus and CINHAL including only RCTs. Methodological quality of the studies was assessed using Cochrane tool. Meta-analyses on HbA1c reduction for diabetes and hospitalization, emergency department (ED) visits and medication for asthma were carried-out.

Results

Of the 3559 papers initially retrieved, 5 regarding diabetes and 19 asthma met the inclusion criteria for the systematic review and 14 for the meta-analyses. Included studies were highly heterogeneous in terms of type of intervention and follow-up duration. Almost all the studies showed an improvement but only few were statistically significant. All studies regarding diabetes showed a low risk of bias (only one RCTs had a high risk of bias in one domain), while almost all RCTs on asthma showed a high risk of bias. The pooled mean differences in favor of the experimental groups were: HBA1c -0.02 (IC95%: -0.26 - 0.22), Hospitalization 0.58 (IC95%: 0.19 - 1.78), Medication -0.10 (IC95%: -0.43 - 0.23), ED Visits 0.82 (IC95%: 0.44 - 1.54).

Conclusions

There is a general agreement about the central role of educational intervention delivered by nurses to pediatric patients and the assessment of the behavioral changes after educational interventions is strongly recommended in pediatric population. However, more efforts are requested in designing studies on patients with asthma and to program more appropriate follow-up and periodic recall in order to engage pediatric patients in the management of their own chronic disease.

Key messages

educational intervention delivered by nurses to pediatric patients with asthma or diabetes type 1 as a fundamental instrument to engage them. more efforts are requested in designing studies on patients with asthma and to program more appropriate follow-up and periodic recall in order to engage pediatric patients.

ED visits and hospital admissions of foreigners for psychiatric disorders in Rome from 2007 to 2018

Background

First generation immigrants are at high risk of psychiatric disorders (PD). Moreover, cultural and migration related factors can act as barriers in the access to care. The aim of this study was to analyze the emergency department (ED) visits and the subsequent admissions to Umberto I, a large teaching hospital in Rome, for PD from 2007 to 2018 and to highlight the differences between Italian citizens and foreigners.

Methods

Adult patients were divided in 11 Nationality Groups (NGs). Basing on ICD9 codes, PD were classified in 5 categories: psychotic, mood, anxiety, personality and substance abuse disorders. Descriptive statistics were conducted for gender, age, educational level and triage. Poisson regression models, adjusted for sociodemographic variables, were used to estimate incidence rate ratios (IRRs) of different NGs, both for visits and hospital admissions, for the five psychiatric categories and for PD as a whole.

Results

In the period of interest there were 11,965 ED visits for PD, of which 19.2% made by foreigners. Compared to Italians, all NGs showed higher percentages of ED visits for PDs, except for Southern Asian (SA) and East-Southern east Asian (ESA); SA and ESA, together with Other Africa population, showed also higher proportion of psychosis. Regarding admissions, ESA had the highest percentage overall, while more than half of foreigner nationality groups had higher percentages of admissions for psychosis than Italians. Poisson regressions showed that only EU citizens have greater risk of ED visit (IRR 1.69, IC95% 1.46-1.96) and of hospital admission for PD (IRR 1.23, IC95% 1.02-1.49) than Italians, while Romanians, SA and ESA have lower risk.

Conclusions

Different risk in ED visits for PDs among NGs can be due to heterogeneity in psychopathology, cultural factors, barriers, and migrant status. More studies are necessary to better understand the needs of foreigners and to enhance their mental health service use.

Key messages

The risk of ED visit and hospital admission for psychiatric disorders differ among foreign populations. Different study design are needed to understand which cultural and migration related factors influence the risks, in order to provide more tailored mental health services for high risk populations.

Multimodal Surveillance of HAI in an Intensive Care Unit of a Large Teaching Hospital

Background

Healthcare associated Infections (HAIs) represent a significant burden in terms of mortality, morbidity, length of stay and costs for patients in intensive care units (ICU). Surveillance systems are recommended to gather data in order to elaborate and evaluate intervention to reduce HAIs risk. Here we describe results of the multimodal surveillance system implemented in the ICU of a large teaching hospital in Rome from April 2016 to October 2018.

Methods

The surveillance system integrated four different approaches: i) active surveillance focused on inpatients; ii) environmental microbiological surveillance; iii) surveillance focused on isolated microorganisms; iv) behavioral surveillance of the healthcare personnel. The system included the molecular genotyping of bacterial isolates through the pulsed field gel electrophoresis (PFGE). Moreover, an intervention to improve personnel adherence to hand hygiene (HH) guidelines was conducted.

Results

Overall, 773 patients were included in the surveillance. The global incidence rate of the device related HAIs was 14.1 (95%CI: 12.2-16.3) per 1000 patient day. Monthly device related HAIs incidence rate showed a decreasing, from 26.9 per 1000 patient day in October 2016, to 4.9 in September 2018. The most common bacterial isolate was K. pneumoniae (20.7%), the 94.0% of which were multidrug-resistant. A total of 305 environmental bacterial isolates were retrieved and the most frequent was A. baumannii (27.2%), that was always multidrug-resistant. Genotyping showed a limited number of major PFGE patters in clinical and environmental isolates. Behavioral compliance to HH guidelines improved after the educational intervention.

Conclusions

The data showed an overall slight decrease over time of the adjusted risk HAIs rates. Through the integration of information gathered from the four approaches, the application of this model returns a precise and detailed view of the infectious risk and of the microbial ecology of the ICU.

Key messages

Multimodal surveillance systems are effective to monitor HAI incidence and to determine the infectious risk. Genotyping techniques allows to characterize and link the clinical and environmental isolates.

Globally, 125 microorganisms were isolated, with Enterobacteriaceae being the most frequent (32%). At the time of the survey, 49.1% patients were receiving antimicrobial therapy. The multivariate analysis showed a significant association between HAI and use of medical devices (OR = 34.30,IC95%:3.69-318.66), length of stay (OR = 1.01, IC95%:1.00-1.02) and the exposure to prophylactic antimicrobial therapy (OR = 0.23, IC95%:0.11 -0.47).

Conclusions

Our HAI prevalence was higher than the European standard (6.7%). This highlights the need of implementing targeted measures to prevent and control HAIs and a continuous monitoring to evaluate the effectiveness of such interventions. Another step could be the elaboration of a survey to investigate the knowledge, attitudes and practices of healthcare workers towards HAIs in order to raise awareness, enhance surveillance strategies and promote educational interventions.

Key messages

It was important to quantify the burden of HAIs in the THPUI in order to identify the main areas for interventions. Several activities will be implemented to contain this problem.

Long-term outcomes in survivors of acute respiratory distress syndrome ventilated in supine or prone position

PURPOSE

The aim of this study is to examine long-term pulmonary function and quality of life in survivors of acute respiratory distress syndrome (ARDS) previously enrolled in a randomized multicenter trial testing prone compared with supine positioning (PSII study) at five Italian centers.

DESIGN

Observational prospective study.

SUBJECTS AND MEASUREMENTS

Pulmonary function [spirometric test, gas exchange, carbon monoxide diffusion capacity (DLCO)], high-resolution computed tomography (CT) scan, and health-related quality of life [Short Form-36 (SF-36) and St. George's Respiratory Questionnaire] were evaluated at 12 months.

RESULTS

Twenty-six patients (13 in each group, mean age 54.1 ± 2.8 years, body mass index 24.5 ± 1.4 kg/m(2), PaO(2)/FiO(2) 117 ± 49 mmHg) were evaluated. There were no significant differences in demographic data, illness severity, or outcome between the prone and supine groups. The overall survival rate was 40%. Pulmonary function was in the normal range without any differences between the two groups. Quantitative lung CT scan analysis showed similar amounts for not aerated (8.1 ± 3.2% versus 7.3 ± 3.4%), poorly aerated (15.3 ± 3.6% versus 17.1 ± 4.9%), and well-aerated (64.0% ± 8.4 versus 70.2 ± 8.4%) lung regions, while overaerated lung region was slightly higher in the prone compared with the supine group (12.5 ± 6.5% versus 5.3 ± 5.5%). Health-related quality of life was similar to in healthy population. However, these patients showed reduction in daily activity specifically due to pulmonary disease as measured by the St. George's Respiratory Questionnaire.

CONCLUSIONS

No differences in pulmonary function or quality of life were observed in this small group of ARDS survivor patients treated in prone versus supine position.

Characteristics and prognostic value of morning dipping of peak expiratory flow rate in stable asthmatic subjects

Characteristics and prognostic relevance of morning dip of peak expiratory flow rate (PEFR) were evaluated in stable asthmatic subjects. Among 246 outpatients monitored four times daily for two weeks, 38 (group A) showed a significant difference between morning reading of PEFR and each of the others; they were compared to 38 randomly selected patients (group B) not showing morning dip in PEFR. Less frequent seasonal course, extrinsic pathogenesis, and sensitization to mites characterized group A; starting airflow limitation was more severe in those with morning dip, but no significant difference between mean PEFR measured throughout two weeks was found. At 6 to 12 weeks, morning dip was not found in 19 of 38 subjects in group A and appeared in seven of 38 subjects in group B, with no clearcut relationship to treatment being evident. At 25 to 104 weeks, no significant difference between therapeutic requirements and the forced expiratory volume in one second was detected; therefore, unlike the short-term, morning dip is not a risk factor for worse long-term prognosis.

Applicability of a simple nasal provocation test in etiologic diagnosis of bronchial asthma

The applicability of nasal challenge for etiologic diagnosis of extrinsic asthma was evaluated by assessing easiness of performance, precision, and cost of a standardized test by metered nebulizer in 20 asthmatics with and without concurrent rhinitis submitted also to skin prick tests and RAST. Although less sensitive than in the group with rhinitis (where precision was 90.4%), the nasal provocation test proved to be an easy, inexpensive, and specific (82.3%) means for contributing to the identification of allergic sensitization in patients affected by asthma alone.
