“Missed a vaccine?” Survey on vaccine hesitancy of high-risk categories in Bologna

Background

Vaccine Hesitancy (VH) is considered by the WHO to be one of the ten threats of the 21st century. The Italian National Plan for Vaccine Prevention, as well as the European Action Plan, have among their objectives that of increasing the adherence to vaccinations both in general population and in categories at higher risk. It is precisely to these latter groups that the action of the Bologna Local Health Authority (LHA) has addressed targeted vaccination campaigns in recent years (e.g., DTP, HepB, PCV/PPV, RZV). Aim of our study was to investigate adherence to the proposed vaccination campaigns.

Methods

An anonymous QR-code scanned survey was administered to adults during the COVID-19 vaccine campaign in February in Bologna, a city in Northern Italy.

Results

A total of 2,321 participants were enrolled, 59% of whom were female. Among healthcare workers (n = 1,417), VH was 45.6% for Hib in 2020, 60.3% in 2019, and 68.3% in 2018; and 14.9% for HepB. Among people with chronic conditions (n = 149), 36.6% did not get the PCV/PPV vaccine. Among RZV vaccine recipients (n = 406), only 11.1% reported having been vaccinated. Women who were at least once pregnant in the last 5 years (n = 124), did not get the anti-pertussis vaccine in 41.9% of cases, and 71.8% of them refused the Hib vaccine. In general, the reasons most often given for missed vaccinations were ‘I did not inform myself enough about this specific vaccine' (ranging from 16.0% for Hib for healthcare workers to 44.8% for RZV), ‘I am not informed about the vaccinations I am entitled to' (27.3% for RZV, 31.8% for PCV/PPV), and ‘I do not find it useful' (46.2% for Hib in healthcare workers).

Conclusions

Our findings show that even in those who accept the COVID-19 vaccine, VH is high for other vaccinations campaigns run by the Bologna LHA. Targeted awareness and designed catch-up actions are needed, especially regarding this group that does not totally stand in the ranks of the so-called ‘no vax'.

Key messages

Vaccine Hesitancy toward other vaccines remains high among those who accept the anti-COVID-19 vaccination. A large number of hesitant respondents report either not being aware of the possibility of vaccination or not being adequately informed about the specific vaccine.

Measles and young adults: the case of the Local Health Authority of Bologna over the last decade

Background

Measles is increasing globally, with a 300% increase in the first three months of 2019 in the WHO European Region. Measles cases recorded annually over the last decade in Italy have been cyclical with the last peak in 2017 with 84 cases per million inhabitants. In the same year, national coercive vaccination measures were introduced for access to educational services. Although the country is again achieving adequate vaccination coverage (VC) for the second dose of MRR (93.2% in 2018), outbreaks can still occur in communities with low VCs.

Methods

The aim of this study was to analyze measles epidemiology in Bologna Local Health Authority (LHA) from 2010 to 2018, focusing on age groups at higher risk of spread. Aggregate data on measles incidence were provided by Bologna HLA and VCs in residents were provided by the Emilia-Romagna Region (RER).

Results

The number of cases in the period of reference was 261 cases, 240 of which were laboratory confirmed (92%). The overall average age was 28.5 years (standard deviation, ds: ±14.73 years). The age group with the highest average incidence rate was 20-24 years (93 per 1.000.000 inhabitants), followed by 25-29 years (88) and 30-34 years (75). With regard to occupation at highest risk of prevalence, students represented the largest group with 22.6% of cases. VC data in residents in RER showed that in the age group 19-35 the fraction of the population not vaccinated with two doses of vaccine decreased significantly in the birth cohorts of the 1990s with a coverage of 6.9% for the 1984 birth cohort. None of the cohorts taken into consideration achieved a VC of 95% for the second dose.

Conclusions

Our results confirm the high proportion of measles cases among young adults. This highlights the need to consider catch-up actions and awareness campaign. For example, by focusing on students without previous documented vaccinations, considering that Bologna is home to tens of thousands of University students every year.

Key messages

The measles epidemiology analysis in the Local Health Authority of Bologna (Italy) over the last decade showed that the young adults (aged 20-35) have the highest average incidence rate of measles. Considering the need to focus on young adults in order to contain new cases of measles; checks on previous vaccinations, catch-up actions and improved awareness campaign are essential.

20 years of Malaria notifications in Bologna AUSL

Background

Notification of confirmed or suspected cases of Malaria is compulsory in Italy. It is essential to optimize control measures in case of imported and indigenous events, considering that the main local vector, Anopheles labranchiae, is still present in Italy.

Methods

Descriptive analysis of malaria cases notified from Bologna local health authority (AUSL) from January 2000 to December 2019.

Results

In the period 2000-2019, out of the 248 Malaria cases notified to the AUSL, 161 were males, and 87 were females, with median age of 33 (IQR: 42-25). All the cases were sporadic and travel-related. The main reasons for travelling were: return to the country of origin (n = 139, 56,0%), tourism (n = 39, 15,7%), work (n = 30, 12,1%), and immigration (n = 13, 5,2%). 86 (34,7%) cases were born in Italy, 43 (17,3%) in Nigeria, 27 (10,9%) in Cameroon, and 17 (6,9%) in Ghana. The cases were imported from Nigeria (n = 56, 22,9%), Cameroon (n = 30, 12,2%), Ghana (n = 26, 10,6%), Ivory Coast (n = 24, 9,8%). Most of the cases were not taking any drug for Malaria chemoprophylaxis (n = 214, 86,6%), 20 cases (8,1%) properly completed the prophylaxis, while 13 cases (5,3%) started chemoprophylaxis but they didn't complete it. The etiological agent identified was Plasmodium falciparum in 176 cases (71,0%), P. vivax in 26 cases (10,5%). Among the former cases 49 (32,2%) were contracted in Nigeria, 29 (19,1%) in Cameroon, 23 (15,1%) in Ghana, 20 (13,2%) in Ivory Coast, 10 (6,6%) in Senegal. 11 (68,8%) cases of P. vivax were contracted in Pakistan.

Conclusions

Epidemiological data collected from Bologna AUSL are consistent with those described from Istituto Superiore di Sanità: the majority of cases was comprised of foreigners, the great majority of cases was imported from Africa. P. Falciparum was prevalent in Africa while P. vivax was prevalent in Asia.

Key messages

The knowledge of the epidemiological situation allows public health workers to advise international travelers focusing on those most at risk of contracting Malaria. Periodic assessment of local epidemiology is necessary to evaluate if data are consistent with those described from international literature.

Hospital statistics for antibiotics: defined versus prescribed daily dose

PURPOSE

Defined daily doses (DDD) are widely used as a unit to measure drug use in hospital and community settings. However, discrepancies exist between DDD and actual prescribed daily dose (PDD). The present study aims at estimating an alternative PDD (PDD-proxy) to calculate rates of systemic antibiotic consumption and to compare these results with those obtained using DDD.

METHODS

The study considered a 9-year period (2004-2012) and included the 17 Health Trusts (HTs) in the Emilia-Romagna Region, Italy. Drugs under study were antibacterials for systemic use (group J01). Data were obtained from the database for hospital drug prescription of Emilia-Romagna Region. The PDD-proxy was estimated by averaging the doses of antibiotic prescriptions from a point prevalence survey for healthcare-associated infections and antimicrobial use, conducted in Emilia-Romagna hospitals in 2012.

RESULTS

Significant discrepancies between DDD and PDD were observed, especially for some antibiotics, resulting in DDD rates that were systematically higher than PDD-proxy rates. In 2012, HT median rates of antibiotic consumption were 90 DDD/100 bed days and 70 PDD-proxy/100 bed-days. However, PDD-proxy and DDD rates showed comparable trends within HTs, although some HTs ranked differently when one or the other measure was used. Interquartile ranges of DDD rates were systematically wider than those of PDD-proxy rates in most years in the period of interest.

CONCLUSIONS

Comparison of HT antibiotic consumption using DDDs may artificially increase observed differences and affect the true HT ranking. Therefore, an additional unit of measurement is useful for in-depth analysis at the local level.

Secular trends in antibiotic consumption in the adult population in Emilia-Romagna, Italy, 2003-2009

Antibiotic resistance is closely related to antibiotic use and Italy is a country with high levels of both antibiotic use and antimicrobial resistance. We analysed the trend in antibiotic use in the community among adults (≥15 years) and elderly, in the period 2003-2009, in Emilia-Romagna, Italy, a region with over 4 000 000 inhabitants. Data regarding antibiotic use were obtained from the regional public health system databases. Between 2003 and 2009 the antibiotic consumption increased from 15.4 to 18.7 defined daily doses/1000 inhabitants per day (DID) (+21.4%, p <0.0001). The prescription rate in 2009 was 2.19 prescriptions/1000 inhabitants per day, an increase of 13.8% compared with 2003. The highest increase in antibiotic use was observed among persons aged 20-59 years (+24.7%). The proportion of inhabitants receiving at least one antibiotic treatment was 36.4% in 2003 and 39.7% in 2009, and the proportions receiving at least three antibiotic treatments were 3.5% and 4.2%, respectively. The H1N1 pandemic was associated, in October and November 2009, with a 37-90% increase in antibiotic use among the 15-19-year and 20-59-year age groups compared with 2007 and 2008. No other difference was observed in any other age group. The analysis per antibiotic class showed increases for penicillin + beta-lactamase inhibitor (from 3.6 to 6.3 DID), quinolones (from 2.6 to 3.0 DID) and macrolides (from 3.1 to 3.7 DID), whereas cephalosporin use was stable (1.4 DID). A steady increase in antibiotic use in the adult population has been observed in the Emilia-Romagna: public health interventions are mandatory to counteract this trend.

Antibiotic treatments for children ages 0-23 months in a northern Italy region: a cohort study

BACKGROUND

This study aims to describe the pattern of antibiotic treatments in the community for children ages 0-23 months in Emilia-Romagna (a northern Italy region) pointing out possible changes of prescribed agents when first treatments in the life of each children are compared to successive ones.

MATERIALS AND METHODS

The Regional Drug Prescription and the Resident Population databases were used as data sources to study the cohort of children born between January 1 and December 31, 2000 and resident in Emilia-Romagna.

RESULTS

The cumulative incidences of children with at least one treatment were 22%, 55% and 82% at 6, 12 and 24 months of age, respectively. Broad spectrum penicillins were the most prescribed antibiotic class for children at their first treatment while cephalosporins were the most prescribed class for successive treatments and when pooling all treatments.

CONCLUSION

Cephalosporins and other second line antibiotics are frequently prescribed to 0 to 23-month-old residents in Emilia-Romagna even when only first treatments are considered; further research is needed to quantify inappropriateness of antibiotic prescription.

Delay in the treatment of pulmonary TB in a changing demographic scenario

OBJECTIVE

To quantify patient and health care delays in the treatment of pulmonary tuberculosis (PTB) in Emilia-Romagna region, Italy, and to study the association between migration status and delay.

DESIGN

All patients with symptomatic PTB, aged >15 years, who were notified in Emilia-Romagna during 2003 and were alive at time of data collection, were included. An individual form was completed for each notified patient by the local health authority officer in charge of surveillance data.

RESULTS

Median patient delay, health care delay and total delay were 7, 36 and 65 days, respectively. Recent migrants (stay in Italy < or = 3 years) had the longest patient delay (16 days), while Italian patients had the longest health care delay (60 days). Migration status was independently associated with both patient and health care delay, although the direction of association changed according to which delay was considered.

CONCLUSION

Public health interventions aiming to reduce delay in treatment of PTB should improve the access of recent migrants to health care and increase suspicion of TB among Italian patients. Studies on delays in treatment of TB should investigate patient delay and health care delay as distinct outcomes.

Barriers to effective tuberculosis control: a qualitative study

SETTING

Emilia Romagna region, Italy.

OBJECTIVE

To explore chest and infectious disease physicians' views of barriers to effective tuberculosis (TB) control and possible solutions.

DESIGN

A series of nine focus groups including a total of 49 physicians.

RESULTS

Three categories of barriers to effective TB control were identified: 1) uncertainty about appropriate clinical practice in the treatment of specific sub-groups of patients, such as the elderly or immigrants; 2) organisational factors, such as the availability of diagnostic services and of sufficient resources; and 3) multiple barriers to a viable and effective TB control programme in a country with a low prevalence of TB.

CONCLUSIONS

The lack of integration and coordination of health services, as well as the scarcity of dedicated TB nurses, were perceived by the participants as crucial barriers to effective TB control. As a result of this study, a regional programme was started with the goals of quantifying the need for TB nurses and developing a better network for required health services. Qualitative studies such as this can be useful in improving TB control in a low-prevalence TB country, to identify problems and increase the participation of key professionals.

Quality of local guidelines for surgical antimicrobial prophylaxis

Surgical antimicrobial prophylaxis (AMP) is an effective measure to prevent surgical site infections. To determine the quality and availability of local guidelines for AMP, a survey was conducted in the public hospitals of a Northern Italian region. The guidelines for "Antimicrobial Prophylaxis in Surgery" by the Scottish Intercollegiate Guidelines Network (SIGN) were used as a standard by which the quality of the local guidelines was compared. The coverage of surgical specialities by local AMP guidelines was 93.1% for hospitals where guidelines had been developed at hospital level and 47% for hospitals where guidelines had been developed by individual surgical departments. Local guidelines recommended AMP for most surgical procedures (96%), including procedures with evidence against the use of antimicrobial prophylaxis (87% of these procedures). Only 8% of all procedure-specific guidelines (PSG) recommended an incorrect timing of AMP (not administering AMP at the induction of anaesthesia), while 41% recommended an incorrect duration (additional antimicrobial doses after completion of the surgical operation). This survey showed that having written protocols at local level does not necessarily mean they comply with available scientific evidence. Thus, the quality of local guidelines needs to be improved.

Antibiotic prescriptions in children

OBJECTIVES

The aim of this study was to evaluate antibiotic prescription for children in Emilia Romagna, a Northern Italian region with 414 880 people aged 1-14 years.

METHODS

The regional Prescription Database of drugs reimbursed by the Italian National Health Service was used in this study. Antibiotic use was estimated as the proportion of children who received at least one prescription during the year 2000 (number of children treated per 100 inhabitants per year). To evaluate the frequency of exposure for each child, all the prescriptions given within a period shorter than 12 days were considered as a single treatment.

RESULTS

In the year surveyed, 511,270 antibiotic prescriptions in 219,257 children were identified. In all, 52.9% of children received at least one antibiotic; this percentage decreased with age, ranging from 70.4% in children 1-2 years old to 35.8% in children >11 years old. Fifty-two per cent of inhabitants under the age of 15 years were treated with systemic antibiotics at least once in the year. Cephalosporins were mostly prescribed in the youngest children, while macrolides were most frequently used in children over 6 years old. In all 3.9% of children were treated with topical antibiotics.

CONCLUSIONS

This study has shown that paediatric antibiotic prescription rates can be derived from analysis of regional drug and resident databases. High antibiotic usage is shown in the paediatric population of Emilia Romagna, similar to that observed in other regions of Northern Italy. Broad-spectrum antibiotics are predominantly prescribed. Comparison with prescription rates from other countries' paediatric populations suggests there is extensive antibiotic overuse in Italy. This could be associated with selection for and dissemination of antibiotic resistance. Interventions are needed to reduce consumption.

Tobacco consumption and sports participation: a survey among university students in northern Italy

Social-demographic information of a total of 1249 students attending the University of Bologna was analyzed by means of an anonymous questionnaire containing 33 questions with particular reference to tobacco smoking and sports activity. Results revealed that 31.6% of the students practise some form of sports regularly (6 hours a week or more), 40.5% occasionally (at least an hour a week for 8 months in a year) and 27.9% do not take part in any kind of sport. Significant differences were seen between those that practise sports (60.4% are non-smokers and 33.5% are habitual smokers) and those that do not (52.9% are non-smokers and 40.1% smoke habitually). The smokers who are active in sports smoke a lower mean number of cigarettes a day than the inactive group and thus belong to the category of light smokers. They also smoke fewer cigarettes on days when they take part in sports activity. As far as knowledge of health risks is concerned, 21.1% of those who practise sports obtained a score between good and excellent compared to 15.9% of those who do not. Although on the whole the results appear to show a certain influence of sports on smoking habits, the kind of study we led and the differences in the number of smokers are not sufficient to consider sports practitioners as a group not at risk for behaviour harmful to the health. Further studies are necessary to verify the cause-effect relationship between sports activity and smoking habits.

Use of anti-asthmatic drugs in Italy: analysis of prescriptions in general practice in the light of guidelines for asthma treatment

Our aim was to analyse anti-asthmatic drug utilisation in primary health care in a Northern Italian region in the light of guidelines for asthma treatment.

METHODS

We collected all prescriptions for anti-asthmatic agents reimbursed in 1998 in six local health authorities (overall population: 1,909,192 inhabitants) of Emilia Romagna (Northern Italy). The asthmatic cohort was defined as the population of subjects aged 20-44 years receiving at least one prescription of an anti-asthmatic agent devoid of indications for transient respiratory diseases. In order to include routine users, the asthmatic cohort was restricted to those subjects with at least one prescription in the first quarter of 1998. Anti-asthmatic agents were classified according to their therapeutic role as follows: maintenance therapy for mild-moderate asthma (Mm); maintenance therapy for severe asthma (Ms); quick relief for mild attack (Qm) and quick relief for severe attack (Qs).

RESULTS

The asthmatic cohort included 11,518 subjects; of these, 47% received only one prescription in 1998. The most frequent regimens were Mm+Qm (25%) and Qm alone (23%). Some regimens appeared not to be in accordance with international recommendations. The main reasons were lack of drugs for quick relief (36%), use of long-term beta(2)-adrenoceptor agonists (Ms drugs) without quick-relief or anti-inflammatory agents (10% of the cohort and 56% of the recipients of Ms drugs) and presence of fixed-dose combinations (27%). In 76% of the patients treated with Mm drugs (mainly inhaled steroids), the total amount of drugs prescribed over the 1-year period covered less than 150 days.

CONCLUSIONS

The use of anti-asthmatic drugs in general practice in Italy does not seem to comply with the international recommendations especially with regard to the use of quick-relief agents. Active interventions to implement guidelines and monitor the choice of drug regimens are warranted.

The therapeutic course as a measure complementary to defined daily doses when studying exposure to antibacterial agents

OBJECTIVE

The defined daily dose (DDD) method may not provide accurate information about exposure to antibacterial agents, owing to their short-term use and the consequently high turnover of subjects. This study was addressed to evaluate whether the number of "therapeutic courses" could offer additional information.

METHODS

Prescription data of antibacterial agents (ATC J01) in Ravenna, Italy (350,000 inhabitants), were studied in 1998. All the prescriptions issued within 10 days were considered as belonging to one therapeutic course (TC). The following measures were compared: DDD/1000 inhabitants/year, number of exposed subjects/1000 inhabitants/year and number of TC/1000 inhabitants/year. In order to compare the number of 10-day TCs with the number of DDDs, the latter was divided by 10 (DDD10). The intensity of drug treatment was also evaluated as the average number of DDDs per TC (therapeutic intensity).

RESULTS

Sixty-one percent of the subjects received only one prescription in 1998. Among the second prescriptions, 69% were issued after a time interval greater than 21 days. The overall prevalence of use was 329 per 1000 inhabitants, the TCs were 525 per 1000 inhabitants and DDD10/1000 inhabitants/year were 470. The therapeutic intensity varied with the age classes (being lowest in the elderly) and with the individual antibiotics used. Two or more antibacterials were used within the same TC in 7% of the cases.

CONCLUSION

The measures considered in this study provided different estimates of exposure to antimicrobial agents. The combined analysis of DDDs and TCs may offer a more reliable information about exposure to antimicrobial agents.
