Impact of the environment on the health: From theory to practice.

The Erice 56 Charter titled "Impact of the environment on the health: from theory to practice" was unanimously approved at the end of the 56th course of the "International School of Epidemiology and Preventive Medicine G. D'Alessandro" held from 3rd to November 7, 2019 in Erice - Sicily (Italy) and promoted by the Study Group of "Environment and Health" of the Italian Society of Hygiene, Preventive Medicine and Public Health. The course, that included lectures, open discussions and guided working groups, was aimed to provide a general training on epidemiological and toxicological aspects of the environmental health impact, to be used by public health professionals for risk assessment, without forgetting the risk communications. At the end of the course 12 key points were agreed among teachers and students: they underlined the need of specific training and research, in the perspective of "One Health" and "Global Health", also facing emerging scientific and methodological issues and focusing on communication towards stakeholders. This Discussion highlight the need to improve knowledge of Health and Environment topic in all sectors of health and environmental prevention and management.

Carbapenem Consumption and Rate of carbapenemresistant gram-negative bacteria: results from the Sicilian Surveillance System.

Conclusion: The results of the present study highlight the need for comprehensive strategies targeting the appropriate use of antibiotics and infection control measures. Background: In the last decades, multidrug-resistant gram-negative bacteria have been increasing and they are involved in severe healthcare associated infections. In treating drug-resistant gram-negative bacterial infections, carbapenems are generally administered as a last choice. However, the rate of carbapenemresistant bacteria is constantly increasing the last years. The aim of the present study is to describe the relationship between the rate of carbapenem-resistant gram-negative bacteria and antibiotic consumption intensity. Study design: In 2017, the Sicilian Region implemented a regional surveillance system to describe and analyze consumption of antibiotics in hospital settings, as well as prevalence of antibiotic resistant microorganisms. Methods: Resistance data were retrospectively collected from routinary clinical antimicrobial susceptibility tests. Resistance rates (RRs) of carbapenems were calculated and Spearman's correlation analysis was performed to investigate the relationship between annual antibiotic consumption and rate of carbapenem resistance. Results: In 2015, the overall prevalence of carbapenem-resistant Klebsiella pneumoniae isolates was 43.9 %, and was positively correlated with beta-lactam consumption (R=0.529, p<0.01), and with carbapenem consumption (R=0.364, p<0.05). In 2016, the overall prevalence of carbapenem-resistant Klebsiella pneumoniae isolates was 53.8 %, and was positively correlated with carbapenem antibiotic consumption (R=0.364, p<0.05). In 2017, the overall prevalence of carbapenem-resistant Klebsiella pneumoniae isolates was 58.7 %, and was significantly positively correlated with carbapenem antibiotic consumption (R=0.427, p<0.05). In 2015, the overall prevalence of carbapenem-resistant Escherichia coli isolates was 6.5 %, and was significantly positively correlated with antibiotic consumption for the ATC class J01 (i.e., antibacterial for systemic use) (R=0.402, p<0.05).

The association of social and behavioral factors with dietary risks in adults: Evidence from the Kardiovize Brno 2030 study.

BACKGROUND AND AIMS: Uncovering the main determinants of diet quality is one of the greatest challenges for Public Health, since it could guide future strategies and interventions against cardiovascular diseases (CVDs). The present cross-sectional analysis of the Kardiovize cohort evaluates the prevalence of dietary risk factors for CVDs and their association with social and behavioural characteristics in a random sample of 1536 adults (aged 25-64 years) from Brno, Czech Republic. METHODS AND RESULTS: A face-to-face health interview guided by structured questionnaires was carried out on socio-demographic characteristics (age, sex, educational level, employment, marital status, income, and household size) and behaviours (smoking status, physical activity, and sleep habits). Twelve dietary risk factors covered by the Global Burden of Diseases comparative risk assessment framework were assessed using a Food Frequency Questionnaire. In general, we observed that the consumption of nearly all healthy foods and nutrients was suboptimal, and that it was also aggravated by high intake of foods and nutrients that constituted dietary risk factors. Moreover, we found several associations of social and behavioural characteristics with specific dietary risk factors. Particularly, being male (ß = 0.466; SE = 0.079; p < 0.001), increasing household size (ß = 0.130; SE = 0.047; p = 0.006), low income (ß = 0.192; SE = 0.091; p = 0.035), and decreasing physical activity level (ß = 0.172; SE = 0.054; p = 0.002) were associated with increasing number of dietary risk factors. CONCLUSION: Thus, our study raises an urgent need for Public Health strategies promoting healthy eating in adulthood, which should be based on traditional and novel determinants of dietary risk.

The Clean Care Contest: promoting hand hygiene among healthcare and medical students.

INTRODUCTION: Despite continuing efforts, compliance rates and knowledge of best practices in hand hygiene remain disappointing. Recognizing that conventional educational tools seem out of touch with young people and that the med and messages contents need refreshing, the Italian Study Group of Hospital Hygiene of the Italian Society of Hygiene, Preventive Medicine and Public Health devised a novel approach to promote the creation of innovative educational tools for improving knowledge of, and compliance with, hand hygiene rules among healthcare and medical students. METHODS: A contest in creating educational material on hand hygiene practices involved university students of nursing and medicine, and of other healthcare degrees. Students from the universities of the GISIO network were invited to create educational material (e.g., videos, posters, presentations, leaflets, and screensavers) to be presented by May 5th 2019 during the World Hand Hygiene Day / Save Lives: Clean Your Hands Global Annual Initiative of the World Health Organization). A local and a national winners were awarded. RESULTS: Three different local and national contests were performed during 2016, 2017 and 2018. During the three-year period, more than 270 educational tools have been developed: 130 (48%) were judged useful for hand hygiene promotion campaigns. The most frequent projects participating in the contests were videos (39%), posters (29%), leaflets (14%), and others (18%) submitted by more than 1,500 students of nursing (40%), medicine (31%), dentistry (7%), and of other healthcare courses in 14 universities. Products were evaluated by a local committee and, subsequently, local winners represented their University in a national contest. CONCLUSIONS: The contest provided a framework for the creation of innovative and potentially effective educational tools via an engaging approach that leveraged student creativity. Given the need to improve compliance rates, this study suggests that new ways can be advantageously explored to teach hand hygiene procedures and increase awareness of the importance of their consistent use among healthcare and medical students.

Hygiene and Public Health courses in Biology curricula: the Italian scenario and the best examples from all over the world.

Different longstanding and emerging challenges for public health have been identified including population ageing, migration, infectious and non-communicable diseases, the environment and climatic changes, increasing risks of misinformation and chronic underinvestment. The multi- and inter-disciplinary public health approach - including biology, epidemiology, biostatistics, anthropology and public policy - raises the need to train experienced professionals in different fields. The education on these matters is fundamental to ensure the human well-being. In the last years, education in schools of public health is changing in response to new evidence-based knowledge, opportunities for improvement and scientific discoveries. In this manuscript the current scenario of teaching Hygiene in all the Italian degree courses in Biology were reviewed and summarized and the most excellent examples of academic training offer of Public Health for Biologists worldwide were provided and discussed as a source of inspiration for novel Masters and PhD degree programmes in Italy.

Dietary patterns and school performance: evidence from a sample of adolescents in Sicily, Italy.

BACKGROUND: Academic success in adolescence is a strong predictor of future wealth, productivity and health. While unhealthy dietary habits might be detrimental for academic outcomes, a positive association between healthy diet and school performance was found in adolescents worldwide. STUDY DESIGN: A total of 213 adolescents (15 to 18 years old; 48% boys), attending three high schools in the urban area of Eastern Sicily, were enrolled in a cross-sectional study. METHODS: Dietary data and informations about weekly consumption of main meals were collected administering a Food Frequency Questionnaire. The Mediterranean Diet Score and Principal Component Analysis were used to identify a priori and a posteriori dietary patterns, respectively. School performance was assessed through school marks, using the previous year as reference. RESULTS: The Mediterranean Diet Score was weakly but positively correlated with performance in Italian, Science and Physical Education (p-values < 0.05). Similarly, the adherence to the prudent dietary pattern weakly positively correlated with marks in Mathematics. In contrast, we demonstrated a weak but significant negative correlation between adherence to the western dietary pattern and the performance in several subjects. The energy dense dietary pattern was instead negatively correlated with mark in Italian. We also showed that adolescents regularly eating all main meals have a better performance in several subjects, when compared to those who skipped at least one meal. CONCLUSION: The promotion of healthy diet in youth should be a priority for Public Health, in order to improve adolescents' quality of life and prevent negative health and social outcomes later in life.

The impact of social determinants and lifestyles on dietary patterns during pregnancy: evidence from the "Mamma & Bambino" study.

BACKGROUND: During pregnancy, maternal dietary patterns play a critical role in determining maternal and new-born health. Recent evidence highlighted the influence of either social determinants and lifestyles on the adherence to different dietary patterns. STUDY DESIGN: In this cross-sectional analysis, we evaluated the association of social determinants and lifestyles with maternal dietary patterns in the "Mother & Child" cohort, a prospective study that enrols mother-child pairs from Catania, Italy. METHODS: Dietary patterns were derived using Food Frequency Questionnaire and Principal Component Analysis. Logistic regression models were used to evaluate the association between socio-demographic factors (i.e., age, educational level and employment status), lifestyles (i.e., smoking status, body mass index, use of folic acid, multivitamin and multi-mineral supplements) and dietary patterns. RESULTS: Overall, 332 women were enrolled and the following dietary patterns were derived: the "western" dietary pattern, characterized by high intake of red meat, fries, dipping sauces, salty snacks and alcoholic drinks; the second one, named "prudent", characterized by high intake of potatoes, raw and cooked vegetables, legumes, rice and soup. Multivariable analysis showed that young age, low educational level and smoking were positively associated with the adherence to the western dietary pattern. In contrast, pre-gestational body mass index was negatively associated with the adherence to the prudent dietary pattern. CONCLUSION: Our results raise the need of strategies for promoting healthy dietary habits among women in their reproductive age, which might also help control their body weight before and during pregnancy. These strategies should be prioritized to young women of low educational level, who generally share other unhealthy behaviours.

Association between eating time interval and frequency with ideal cardiovascular health: Results from a random sample Czech urban population.

BACKGROUND AND AIMS: The frequency and timing of meals may affect cardiovascular health (CVH) outcomes, but large-scale epidemiological studies are lacking. The aim of this study was to understand the relationship between eating time interval and frequency, and measures of ideal CVH in the Kardiovize Brno cohort study, a random urban sample population in Central Europe. METHODS AND RESULTS: 1659 members of the Kardiovize Brno 2030 cohort were included in a cross-sectional study (mean age = 46.86 years; 44.6% male). Exposure variables were eating time interval and frequency, and skipping meals. Primary outcomes were indices of CVH, including body mass index, diet, physical activity, smoking, blood pressure, glucose and cholesterol, and the composite CVH score. Cluster analysis and binary logistic regression analysis were used to evaluate eating habits and the association between variables. After adjustment for well-known risk factors, subjects who skipped breakfast or the afternoon snack had a higher risk of poor CVH (OR = 1.613; 95%CI = 1.121-2.320; p = 0.010; OR = 1.409; 95%CI = 1.110-1.788; p = 0.005, respectively). Moreover, we identified three clusters of individuals based on eating habits; from cluster 1 to cluster 3, eating time interval and frequency increased and this was associated with increases in CVH score from 8.70 (SEM = 0.10) in cluster 1, and 9.06 (SEM = 0.08) in cluster 2 to 9.42 (SEM = 0.09) in cluster 3 (p-trend = 0.019). CONCLUSIONS: Our findings suggest that skipping breakfast or the afternoon snack are risk factors for poor CVH, while higher eating time interval and frequency may promote ideal CVH.

Hospital Hygiene and Infection Prevention and Control in Italy: state of the art and perspectives.

Although hospital hygiene has a long history in Italy it is necessary to reflect about it because of the innovation in healthcare systems and because of the evolution due to European Union related activities. Different traditions exist in European countries about hospital hygiene and European Centre for Disease Prevention and Control (ECDC) adopted the term of "infection control and hospital hygiene" which includes all the engaged European healthcare professionals. We propose to modify hospital hygiene as "healthcare organisation hygiene" in order to focalise the attention to all care settings not only hospitals and to adopt the following definition: "all activities aimed to guarantee, in an appropriate, scientifically sound and efficient way, that structures and processes support healthcare practices in a safe comfortable and healthy environment both for patients, caregivers and healthcare workers". Hospital hygiene and its professionals, besides the long tradition, still remain a relevant pillar in guaranteeing quality and safety of healthcare in Italy.

The commitment of the GISIO-SItI to contrast Healthcare-Associated Infections and the experience of prevalence studies in Sicily.

Surveillance of Healthcare-Associated Infections (HAIs) is essential to improve the quality of health services. The aim of this paper is to report the commitment of the Italian Study Group of Hospital Hygiene (GISIO) of the Italian Society of Hygiene, Preventive Medicine and Public Health (SItI) describing some experiences to contrast HAIs and antimicrobial resistance. Particularly, the commitment to contrast HAIs in intensive care with the SPIN-UTI project - Italian Nosocomial Infections Surveillance in ICUs, and in surgery with the ISCHIA project - Infections of Surgical Site in Arthroplasty Interventions - were described. Furthermore, some activities conducted in Sicily using repeated prevalence studies were reported. The experiences reported confirmed that surveillance is essential to provide health services with information, guidance and tools to manage effectively the risk of HAI and antimicrobial resistance and to monitor the level of achievement of control programmes.

Heating, ventilation and air conditioning (HVAC) system, microbial air contamination and surgical site infection in hip and knee arthroplasties: the GISIO-SItI Ischia study.

BACKGROUND: Recent studies have questioned the role of unidirectional airflow ventilation system in reducing surgical site infection (SSI) in prosthetic implant surgery. The aim of the ISChIA study ("Infezioni del Sito Chirurgico in Interventi di Artroprotesi" which means "Surgical site infections in arthroplasty surgery") was to evaluate, as a contribution to this debate, the association between heating, ventilation and air conditioning systems, microbial air contamination and surgical site infection in hip and knee arthroplasty. METHODS: The study was performed from March 2010 to February 2012 in 14 hospitals, for a total of 28 operating theatres: 16 were equipped with vertical unidirectional airflow ventilation (U-OTs), 6 with mixed airflow ventilation (M-OTs), 6 with turbulent airflow ventilation (T-OTs). Microbial air contamination in the operating theatre was evaluated by means of passive (Index of Microbial Air contamination, IMA) and active (Colony Forming Units per cubic metre, cfu/m3) sampling. SSI surveillance was carried out according to the Hospitals in Europe Link for Infection Control through Surveillance protocol. RESULTS: A total of 1,285 elective prosthesis procedures (61.1% hip and 38.9% knee) were included in the study. The results showed a wide variability of the air microbial contamination in operating theatres equipped with unidirectional airflow. The recommended values of ≤2 IMA and ≤10 cfu/m3 were exceeded, respectively, by 58.9% and 46.4% of samples from U-OTs and by 87.6% and 100% of samples from M-OTs. No significant difference was observed between SSI cumulative incidence in surgical procedures performed in U-OTs compared with those performed in T-OTs. A lower risk of SSI, even though not statistically significant, was shown in surgical procedures performed in U-OTs with a microbial air contamination within the recommended values (≤2 IMA and ≤10 cfu/m3) compared with those performed in U-OTs where these limits were exceeded, and compared with those performed in T-OTs with microbial air contamination within the recommended values for this type of OTs (≤25 IMA, ≤180 cfu/m3. CONCLUSION: ISChIA study did not show a protective effect of unidirectional airflow compared with turbulent airflow in arthroplasty surgery. However, the frequent exceeding of recommended air microbial contamination values in OTs equipped with unidirectional airflow, and the lower SSI risk in surgical procedures performed in compliant U-OTs compared with those performed in non-compliant U-OTs and with those performed in compliant T-OTs, suggest the need of further studies, which should consider air microbial contamination and other aspects of SSI prevention that may negate the potential benefits of the ventilation system; differences in intrinsic and extrinsic risk factors, medical treatment and surgical technique are also to be considered. Training interventions aimed at improving the behaviour of operators are essential.

Appropriateness of perioperative antibiotic prophylaxis in two Italian hospitals: a pilot study.

BACKGROUND: Appropriate perioperative antibiotic prophylaxis has been shown to be an effective measure for preventing surgical site infections and to avoid complications including increased antimicrobial resistance. The objective of the present study was to evaluate the appropriateness of perioperative antibiotic prophylaxis in two Italian hospitals. STUDY DESIGN: In 2016 a survey was prospectively carried out at two hospitals (identified as A and B) and all patients who underwent a surgical operation were enrolled. METHODS: For each patient, perioperative antibiotic prophylaxis data were collected and appropriateness of perioperative antibiotic prophylaxis was assessed according to the national guidelines (SNLG-17, 2011). RESULTS: During the study period, 107 and 467 operations were included. Compliance to perioperative antibiotic prophylaxis according to indication was 72.3% (hospital A) and 77.9% (hospital B). Perioperative antibiotic prophylaxis was administered <60 min before the skin incision in 89.1% of surgical procedures in hospital A and in 78.4% in hospital B. In hospital A, the recommended molecule of antibiotic was correctly administered in 87.8% of surgeries (n= 36), while, in hospital B, the antibiotic was correctly administered only in 9.8% of surgeries. Antibiotic prophylaxis was not extended postoperatively or did not exceed 24 hours after the end of the surgery in 99% and 8.9% of the procedures in hospital A and B, respectively. CONCLUSION: Our study found an overall low compliance to perioperative antibiotic prophylaxis mainly regarding antibiotic choice and total duration of prophylaxis. The Italian Study Group of Hospital Hygiene - Italian Society of Hygiene, Preventive Medicine and Public Health, together with the National Association of Hospital Physician, promoted the implementation of the project "Choosing wisely - Hospital Hygiene", and, among the list of the 5 procedures with the highest evidence of inappropriateness, the timing and the duration of administration of perioperative antibiotic prophylaxis have been included and a multicenter study has been launched to evaluate the appropriateness of perioperative antibiotic prophylaxis components in all the participating Italian hospitals.

The effectiveness of educational interventions in university training on hospital hygiene: results of action research.

BACKGROUND: The Italian Study Group of Hospital Hygiene of the Italian Society of Hygiene, Preventive Medicine and Public Health promoted and conducted a study on teaching hospital hygiene, with particular reference to the prevention and control of healthcare-associated infections, with the aim of developing effective educational material starting from the results collected. MATERIAL AND METHODS: First of all, a survey was carried out, targeting lecturers in hospital hygiene, with the purpose of investigating their perceptions regarding this issue. The available scientific literature was also reviewed in order to identify effective educational/teaching strategies for the prevention of healthcare-associated infections, so that valid training interventions could be subsequently developed. Finally, a trial-training intervention was implemented, and specific audio-visual teaching material was also tested. RESULTS: The overall response rate to the survey was 42%, with good country-wide representativeness. The level of awareness of hospital hygiene issues by students resulted higher among trainee nurses (65%) than among medical students (44%). The teaching staff identified alternative educational methodologies to substitute the classical lecture (e.g.: case discussions) and, in most cases, the alternative solution appeared to be preferable. The teaching of hospital hygiene was better integrated with other disciplines and professional training activities in the degree courses for nurses than in those for doctors; the total number of hours assigned to such teaching was variable. The literature review highlighted that various educational approaches are used. The most common are presentations or lectures, but videos, posters, questionnaires and e-learning strategies are also used. Combining different instruments when designing an educational programme has proven to be an effective strategy. The training activity tested was positively evaluated by the participants; the possibility of multidisciplinary exchange of knowledge was particularly appreciated. CONCLUSION: Having considered the issue of teaching hospital hygiene from the points of view of the different protagonists involved (educators and students), this enabled us to develop useful training material and a proposal for a shared educational intervention. The subject of hospital hygiene, in particular the one related to the prevention of healthcare-associated infections, is addressed in various courses and with different modalities; it is, therefore, important to standardize course contents and teaching methods, in order to facilitate multidisciplinary debate, especially starting from case studies.

Epidemiology of intensive care unit-acquired sepsis in Italy: results of the SPIN-UTI network.

BACKGROUND: Sepsis is the major cause of mortality from any infectious disease worldwide. Sepsis may be the result of a healthcare associated infection (HAI): the most frequent adverse events during care delivery especially in Intensive Care Units (ICUs). The main aim of the present study was to describe the epidemiology of ICU-acquired sepsis and related outcomes among patients enrolled in the framework of the Italian Nosocomial Infections Surveillance in ICUs - SPIN-UTI project. STUDY DESIGN: Prospective multicenter study. METHODS: The SPIN-UTI network adopted the European protocols for patient-based HAI surveillance. RESULTS: During the five editions of the SPIN-UTI project, from 2008 to 2017, 47.0% of HAIs has led to sepsis in 832 patients. Overall, 57.0% episodes were classified as sepsis, 20.5% as severe sepsis and 22.5% as septic shock. The most common isolated microorganisms from sepsis episodes were Acinetobacter baumannii, Klebsiella pneumoniae and Pseudomonas aeruginosa. The case fatality rate increased with the severity of sepsis and the mean length of ICU-stay was significantly higher in patients with ICU-acquired sepsis than in patients without. CONCLUSION: Our study provides evidence that ICU-acquired sepsis occurs frequently in Italian ICU patients and is associated with a high case fatality rate and increased length of stay. However, in order to explain these findings further analyses are needed in this population of ICU patients.

Results of a survey of procedures for cleaning and disinfecting ambulances.

BACKGROUND: In 2014, the Italian Study Group of Hospital Hygiene of the Italian Society of Hygiene, Preventive Medicine and Public Health (GISIO-SItI), in collaboration with the National Association of Medical Hospital Managers (ANMDO), conducted a survey on the availability of procedures for cleaning and disinfecting ambulances in order to assess the practices in use. METHODS: An online questionnaire was prepared through the Survey Monkey® platform and a web link access was sent to a convenience sample of ANMDO doctors working in healthcare management in public and private healthcare facilities. RESULTS: Ninety-six questionnaires were collected (26% response rate). In 73% of cases there was a procedure for cleaning and disinfecting ambulances, which had been produced at a company level (67%) and involved various professionals. In 21% of cases the procedure had been prepared in expectation of an epidemic or following an epidemic (5%). The recommendations had been presented to the staff (90%), in 28% of cases through training events with verification of the knowledge acquired. Monitoring of the implementation of the procedure is planned in the majority of cases (88%), mainly through direct observation (92%). In 67% of cases the tender specifications for ambulance services did not include a section dedicated to cleaning and disinfection and, in the absence of a procedure, this was provided by the hospital in only 51% of case. CONCLUSION: This survey represented a first step towards the development of guidelines for standardising procedures and providing indications useful for their evaluation and monitoring their implementation.

Essential strategies in HAI prevention and control: performance assessment through the implementation of the HAI-CoSIP tool of the GISIO-SItI group. A pilot study in a sample of Italian Organizations.

BACKGROUND: Healthcare-Associated Infections are a great concern for worldwide healthcare systems and represent a considerable threat to patient safety, leading to adverse clinical outcomes. A defined panel of indicators represents a key element to guide Healthcare Organizations towards identification of main gaps, implementation of effective actions and continuous improvements on Healthcare-Associated Infections prevention and control activities. A review on accreditation systems conducted by the Italian Study Group of Hospital Hygiene of the Italian Society of Hygiene Preventive Medicine and Public Health revealed a substantial heterogeneity of implemented standards and led to the development of a core set of indicators and requirements for Healthcare-Associated Infections' prevention and control within the hospital setting. The main aim of the study was to test the feasibility of the Healthcare-Associated Infections' prevention and control within the hospital setting tool to calculate performance scores on a sample of Italian Healthcare Organizations and to identify major critical issues. The potential benefits of the possibility of future implementation of the tool within Institutional Accreditation Programs is discussed. STUDY DESIGN: Cross sectional pilot survey. METHODS: The Healthcare-Associated Infections' prevention and control within the hospital setting included 96 criteria and 20 key areas including an area for outcomes indicators. For applicable criteria, standards fulfilment was evaluated according to a 4 point Likert scale. A composite score was calculated for each Healthcare Organization and five performance levels were identified. Data were further analysed by computing performance scores at the level of each area and requirement. RESULTS: 20 Healthcare Organizations agreed to take part in this pilot study including two rehabilitative Healthcare Organizations. Among the whole sample a mean of 12.20% of requirements resulted not fulfilled, leaving space for further improvements. Critical areas were easily identified and the instrument was able to capture substantial differences between Healthcare Organizations. Only a few number of standards resulted "Not Applicable" (Mean = 4.71%) and most of them regarded Rehabilitative Healthcare Organizations. Mean composite performance index resulted 74.06% (SD = 16.96, range 36.30 - 94.27%); area of outcome indicators obtained a mean score of 56.17. CONCLUSION: The Healthcare-Associated Infections' prevention and control within the hospital setting resulted an useful tool to assess Healthcare Organizations' performance in the field of Healthcare-Associated Infections prevention and control and to identify necessary actions for further improvements. The distribution of total scores by Healthcare Organizations showed a high heterogeneity. Implementation of the Healthcare-Associated Infections' prevention and control within the hospital setting tool as an institutional accreditation tool may help to drive the required harmonization at a national level of Healthcare-Associated Infections management and control strategies and overcome current substantial regional differences.

Procedures in endoscope reprocessing and monitoring: an Italian survey.

BACKGROUND: The high diffusion of endoscopes worldwide and the need for effective reprocessing methods requested the development of guidelines and implementation of surveillance procedures at local level. STUDY DESIGN: In order to collect data on everyday's practice and adherence to available guidelines, endoscopy units from different public institutions were surveyed using a dedicated questionnaire. METHODS: Between July and November 2015 a survey was carried in 12 main hospitals from 10 different Italian regions, involving 22 endoscopy units. The state of the art of national and international guidelines was investigated to compare the protocols adopted at local level. RESULTS: In all the surveyed hospitals, the reprocessing activity is based on pre-established protocols in adherence with principal guidelines. Enzymatic detergents, which are recommended by the international guidelines, are used in 55.6% of units and peracetic acid is currently the most widely used chemical disinfectant. Discrepancies were observed in the application of periodic quality controls. CONCLUSION: Updated guidelines are generally applied in reprocessing practice. Quality controls may represent a critical issue to improve effectiveness and surveillance. The whole of acquired data can promote a positive trend towards the application of best practices.

A multicentre study on epidemiology and prevention of needle stick injuries among students of nursing schools.

INTRODUCTION: Among the health professions with a long period of training, the students of the Nursing Bachelor's Degree are the most exposed to biological risk resulting from accidents, in particular with needles and cutting edges. The aim of the study was to estimate the frequency and the circumstances for the occurrence of needle stick injuries, as a knowledge base for targeted prevention interventions. METHODS: The study was carried out between May and July 2017 in 11 Universities in Italy and 1 in Albania (associated with the "Tor Vergata" University of Rome). An anonymous semi-structured questionnaire was proposed to 1st (second semester), 2nd and 3rd year students of Nursing Bachelor's Degree. RESULTS: A total of 2742 questionnaires were collected. The average age of participants was 22.9 years (median 22, range 19-60 years), 73% of whom were females. A total of 381 injuries were reported. Three hundred and sixteen students (11.8%) underwent at least 1 injury (12.7% among females, 9.7% among males); 41 students declared two or more injuries; four students did not report the number of injuries occurred. The first injury occurred, as an average, 17 days after the start of the internship (median 15 days) and, in 25% of the cases, during the first 9 days. The highest percentage of accidents occurred during the first internship (25.3% of the total) and decreased with the progress of the training path. The injuries occurred in 38% of cases during drug preparation, 24% when disposing of sharp devices, 15% while re-capping needles, 13% during blood sampling and 10% in other circumstances. In 51.2% of cases, the needle was not sterile. Among the nursing students who suffered a needle stick injury, 58.1% declared that they had performed the post-exposure prophylaxis. 96% of students stated to be vaccinated against Hepatitis B virus. Amongst the students who had their serological status checked (74%), 18% stated the antibody titre was not protective. 49.8% of students answered to have been trained in advance on the correct procedures to avoid needle stick and cutting edges injuries in each clinical ward attended, 41.2% referred that this occurred only in some wards and 10% in no ward at all. CONCLUSION: The results of this study show a high percentage of needle stick injuries in students of the Nursing Bachelor's Degree. Therefore, there is a need for careful reflection on the most effective methods of targeted training acquisition of knowledge, skills and behavioural models useful for the exercise of the profession.

Hospital hygiene in Italy: the GISIO-SItI survey.

BACKGROUND: In Italy there are no rules concerning the establishment of a hospital hygiene structure in hospitals and other healthcare settings, and the hospital organization plans vary widely. The aim of the survey, carried out by the Italian Study Group of Hospital Hygiene of the Italian Society of Hygiene, Preventive medicine and Public health, was to evaluate the presence in the hospital organization plan of a structure referred to as Hospital hygiene, or including in its denomination the words "hygiene" or "hospital hygiene", the activities carried out, the relation to other areas, like patient safety, the type and quantity of professionals involved, the strengths and the critical aspects. METHODS: A semi-structured questionnaire was administered to Healthcare Trusts representing all Italian Regions through the members of the above Study Group. RESULTS: 35 Trusts, 13 in Northern, 8 in Central, 14 in Southern Italy (including Sicily and Sardinia), completed the questionnaire. In 19 Trusts (54.3%) a structure whose denomination included the words "hospital hygiene" or "hygiene" was present. The activities related to the management of infectious risk were most represented, carried out autonomously or in collaboration, but many other activities were covered. In all hospitals the activities of the Hospital Hygiene Unit inter-linked with those of the clinical risk, with different forms of collaboration. CONCLUSION: This survey, even though on a limited sample, provided a picture of hospital hygiene at a national level, showing a considerable heterogeneity and highlighting critical issues but also strengths. It is essential to share organizational and management models that enhance and promote hospital hygiene, to ensure the appropriateness of healthcare practices offered in a safe and comfortable environment to patients, operators, and visitors.

Knowledge, experiences, and attitudes toward Mantoux test among medical and health professional students in Italy: a cross-sectional study.

BACKGROUND: The World Health Organization's Action Framework for tuberculosis elimination in low-tuberculosis incidence countries includes the screening for active and latent tuberculosis in selected high-risk groups, including health care workers. In this context, medical and health profession students, exposed to nosocomial tuberculosis transmission during training and clinical rotations, are target populations for tuberculosis screening. No updated data are available on tuberculosis screening practice and knowledge of medical and health profession students in Italy. METHODS: Within the activities Italian Study Group on Hospital Hygiene of the Italian Society of Hygiene, Preventive Medicine and Public Health, we carried out a multicentre cross-sectional study to assess knowledge, attitude and practices on tuberculosis prevention and control among Medical, Dentistry, Nursing and other health professions' students. Students were enrolled in the study on a voluntary basis and were administered a previously piloted structured questionnaire. Logistic regression models were applied to explore knowledge on tuberculosis prevention by selected socio-demographic variables and University-based tuberculosis prevention practice. RESULTS: Students of seventeen Universities across Italy participated in the study, and 58.2% of them received compulsory tuberculin skin test either at enrollment or while attending clinical practice. A total of 5,209 students filled the questionnaire. 37.7% were medicine and dentistry students (Group 1), 44.9% were nursing students (Group 2) and 17.4% were other health professions' students (Group 3). Age and gender had different distributions by groups, as well as knowledge and practice on tuberculin skin test. 84.4% of the study population (95% CI = 83.3-85.3) was aware of the existence of the tuberculin skin test, 74.4% (95% CI = 73.2-75.6) knew what is the first-level screening test for latent tuberculosis and only 22.5% (95% CI = 21.4-23.6) knew how to proceed after a positive tuberculin skin test result. Overall, knowledge on tuberculosis prevention was higher in Group 2 and lower Group 3, as compared to Group 1. CONCLUSION: In Italy, the knowledge on tuberculosis screening among University students is generally good. To reduce some of the criticalities found among the different study courses, it would be appropriate to harmonize both the regulations on tuberculosis screening practices for admission to University courses, and the educational activities on the topic of tuberculosis, to be extended to all workers involved in health care setting.
