Impact of an empiric antimicrobial therapy manual on antimicrobial usage and multidrug resistant organism trends in a large Italian teaching hospital.

Aim: To evaluate the changes in antimicrobial consumption and multidrug-resistant microorganism trends after introducing an empiric antimicrobial therapy manual to support antimicrobial stewardship. Methods: A 4-year prospective interventional study assessed the effect of introducing an empiric antimicrobial therapy manual in medical and surgical wards during two periods: pre-intervention period (January 2015-May 2017) and post-intervention period (June 2017-December 2019). Outcomes included microorganism trends of bloodstream infections (BSI) for Klebsiella pneumoniae carbapenemase-producing bacteria (KPC), extended spectrum beta-lactamase ESBL-E. coli, meticillin-resistant Staphylococcus aureus (MRSA) and Candida albicans. Also, Clostridioides difficile infection (CDI) episodes were included. Rates were normalised per 1000 patient-days (PD). Antimicrobial consumption was assessed as defined daily dose (DDD)/1000 PD in interrupted time series analysis. Results: In medical wards, we observed a significant decrease in the consumption of piperacillin-tazobactam and a decrease in the trends of tigecycline and vancomycin consumption. In surgical wards, there was a significant decrease in consumption of fluoroquinolones and piperacillin-tazobactam. This decrease was maintained in trend for all the antimicrobials but was significant for tigecycline only. In medical wards, there was a significant reduction of MRSA and C. albicans. In surgical wards, we observed a decrease in MRSA, ESBL-E. coli, C. albicans and CDI. KPC cases decreased by 22.5% in medical wards and 74.3% in surgical wards. Conclusion: The results suggest that a persuasive educational approach to antimicrobial stewardship, with the introduction of an empiric antimicrobial manual and continuous education, resulted in reductions in both antimicrobial use and healthcare-associated BSI caused by multidrug-resistant organisms. More studies with longer follow up are needed to investigate the effect of antimicrobial stewardship on clinical outcomes.

Stress in Medical Students: PRIMES, an Italian, Multicenter Cross-Sectional Study.

Medical students (MSs) are healthcare workers and must also cope with education-related stressors. This study aims to assess factors associated with perceived stress in Italian MSs. A cross-sectional study was conducted in 12 Italian medical schools (MSCs) in November 2018. A questionnaire assessed socio-demographic characteristics, habits, opinions about MSC, and concerns about the future. Stress was assessed with the PSS-10. Descriptive and univariable tests were performed. A linear model was fitted to find associations of the PSS-10 score with characteristics. There were 2513 collected questionnaires. Median PSS-10 score was 18 (IQR 11). Median age was 22 (IQR 4) and 61% of the sample was female. Female gender, being part of a sexual minority, poor financial situation, competitive atmosphere, having hobbies, resting, and sleeping hindered by MSC were characteristics associated with higher PSS-10 scores. Current relationship, good family relationship, and no concerns about the future were protective factors. Being part of sexual minorities had greater effects in students not living away from home, while in the other group it was not having satisfying friendships. Medical students suffer higher levels of stress than the general population, and many MSC stressors are associated. Living away from home modifies risk and protective factors, offering the possibility to tailor group-specific interventions.

SARS-CoV-2 infection: efficacy of extensive vaccination of the healthcare workforce in a large Italian hospital.

BACKGROUND: A prospective observational study involved 13,787 Health Care Workers (HCWs) of a large hospital to assess the effectiveness of a SARS-CoV-2 mRNA vaccine. METHODS: The daily incidence of infections was estimated from 1st October 2020 to 30th April 2021 and compared with that of the province of Turin (2.26 million). In the middle of this period, a mass vaccination began among HCW, and its effect was assessed. RESULTS: In the first half-period, 1,163 positive HCWs were observed, the average daily incidence rate per 100,000 being 79.58 (± 15.58; 95% CI) compared to 38.54 (± 5.96; 95% CI) in the general population (p<0.001). The vaccination campaign immunized 9,843 HCWs; among them, the average daily incidence was 14.23 (± 2.73; 95% CI) compared to 34.2 (± 2.95; 95% CI) in the province (p<0.001). Among fully vaccinated HCW, 59 cases were observed, giving rise to an incidence of 6.3 (± 2.66; 95% CI) much lower than in the province (p<0.001). In the second half of the observation period, the RR for HCWs compared to the province dropped from 2.07 (1.96 - 2.18; 95% CI; p<0.001) to 0.5 (0.42 - 0.58; 95% CI; p<0.001) and to 0.17 (0.13 - 0.22; 95% CI; p<0.001) for unvaccinated and vaccinated HCWs, respectively. The RR of vaccinate HCW was 0.43 (0.31 - 0.58; 95% CI; p<0.001) compared to unvaccinated. In the second half of the observation period, unvaccinated HCWs had a RR of 0.21 (0.18 - 0.25; 95% CI; p<0.001) as compared to the first one. A linear regression model (R2 = 0.87) showed that every percent increase in vaccinated HCWs lowered daily incidence by 0.94 (0.86 - 1.02; IC 95%; p<0.001). Vaccinated HCWs had a RR of 0.09 (0.07 - 0.12; 95% CI; p<0.001) compared to unvaccinated HCWs, which led to estimated effectiveness of the two-dose vaccine of 91 % (± 3 %; CI 95%) similar to that reported by the manufacturer.

Cost-Effectiveness Analysis of the Prophylactic Use of Ertapenem for the Prevention of Surgical Site Infections after Elective Colorectal Surgery.

Standard surgical antimicrobial prophylaxis (SAP) regimens are less effective in preventing surgical site infections (SSIs) due to rising antimicrobial resistance (AMR) rates, particularly for patients undergoing colorectal surgery. This study aimed to evaluate whether ertapenem should be a preferred strategy for the prevention of SSIs following elective colorectal surgery compared to three standard SAP regimens: amoxicillin-clavulanate, cefoxitin, and cefazolin plus metronidazole. A cost-effectiveness analysis was conducted using decision tree models. Probabilities of SSIs and AMR-SSIs, costs, and effects (in terms of quality-adjusted life-years) were considered in the assessment of the alternative strategies. Input parameters integrated real data from the Italian surveillance system for SSIs with data from the published literature. A sensitivity analysis was conducted to assess the potential impact of the decreasing efficacy of standard SAP regimens in preventing SSIs. According to our models, ertapenem was the most cost-effective strategy only when compared to amoxicillin-clavulanate, but it did not prove to be superior to cefoxitin and cefazolin plus metronidazole. The sensitivity analysis found ertapenem would be the most cost-effective strategy compared to these agents if their failure rate was more than doubled. The findings of this study suggest ertapenem should not be a preferred strategy for SAP in elective colorectal surgery.

Beyond COVID-19: a cross-sectional study in Italy exploring the covid collateral impacts on healthcare services.

With COVID-19, populations are facing unmet health needs due to fear of contagion, lockdown measures and overload of Healthcare services (HCS). The COCOS study aimed to investigate reduced healthcare access among Italian citizens, additionally looking for specific subgroups that will primarily need health services in the next future. A cross-sectional online survey was performed during the Italian lockdown between April and May 2020. Descriptive, univariable and multivariable (logistic regression models) analyses were performed: results are expressed as Odd Ratios and Adjusted Odd Ratios (ORs and AdjORs). Totally, 1,515 questionnaires were collected. Median age was 42 years (IQR 23), 65.6% were females. Around 21.8% declared to suffer from chronic diseases. About 32.4% faced a delay of a scheduled Medical Service (MS) by provider decision, 13.2% refused to access scheduled MS for the fear of contagion, and 6.5% avoided HCS even if having an acute onset issue. Alarmingly, 1.5% avoided Emergency Department when in need and 5.0% took medications without consulting any physician: patients suffering from chronic conditions resulted to be more prone to self-medication (AdjOR [95% CI]: 2.16 [1.16-4.02]). This study demonstrated that indirect effects of COVID-19 are significant. Large groups of population suffered delays and interruptions of medical services, and the most vulnerable were the most affected. Immediate efforts are needed to reduce the backlog that HCSs incurred in.

Interrupted time series analysis of the impact of a bundle on surgical site infections after colon surgery.

BACKGROUND: Surgical site infections (SSIs) are monitored in Italy through a national surveillance system. A 4-element bundle was introduced in 2012, consisting of: appropriate preoperative shower and hair removal, perioperative normothermia, and antibiotic prophylaxis. The aim of this study was to evaluate the effect of the intervention on SSI rates after colon surgery. METHODS: A retrospective cohort study was conducted between 2008 and 2019 in 29 hospitals of northern Italy. An interrupted time series analysis (ITSA) was modeled to assess the bundle's impact on SSI trends. Logistic regression was performed to identify predictors of SSI among procedures performed in the postintervention period, comparing full and partial bundle compliance. RESULTS: Data of 5487 colon surgery procedures were collected (1243 preintervention and 4244 postintervention). The ITSA identified a significant change in the monthly postintervention SSI trend of -0.19% and a change in level of -2.09%. A significant protective effect of full bundle compliance compared to partial bundle compliance (OR 0.74, P.043) was found, whereas the single effect of the bundle elements was nonsignificant. CONCLUSIONS: Results of this study suggest this relatively simple bundle protocol is effective in reducing SSI risk.

Healthcare Workers' (HCWs) attitudes towards mandatory influenza vaccination: A systematic review and meta-analysis.

Influenza is a disease responsible for thousands of deaths every year. Although healthcare workers (HCWs) represent a way of contagion for patients, vaccination coverage among them is low. Mandatory vaccination has been proposed, but controversies remain. This systematic review and meta-analysis aimed to assess the acceptance of mandatory vaccination by HCWs, and to investigate associated characteristics. MEDLINE, Scopus, Embase, PsycInfo, CINAHL and Web of Science were used to search for studies assessing the topic. PRISMA statements were followed. Of the 13,457 univocal records found, 52 studies were included in the systematic review and 40 in the meta-analysis. The pooled proportion of HCWs accepting the policy was of 61% (95% CI: 53%- 68%) but with great heterogeneity between continents (from 54% in Europe to 69% in Asia) and in different professionals (from 40% in nurses to 80% in students). Vaccinated HCWs agreed more frequently with mandatory vaccination than non-vaccinated ones. More studies that consider mandatory vaccination acceptance as the main outcome are needed, but the results of this study confirm that in some settings the majority of HCWs favour mandatory vaccination. This, combined with effects that a flu epidemic could have if overlapped to pandemics with similar symptoms, requires renewed considerations on mandatory vaccination.

Orthorexia Nervosa, a challenging evaluation: analysis of a sample of customers from organic food stores.

An excessive control of quality of food can turn into Orthorexia Nervosa (ON). The organic store customers (OSCs) can be apopulation at risk for ON. The aims of this study were to assess ON symptoms prevalence among them, comparing them with non-OSCs and investigate potential predictors of ON. Across-sectional survey was carried among 121 OSCs and 119 non-OSCs. The questionnaire assessed socio-demographic characteristics and investigated current dietary habits. The main outcome measures used were ORTO-15 and Eating Habits Questionnaire (EHQ). Chi-squared analyses were performed to assess differences between groups (OSCs and non-OSCs). Logistic and linear regressions were performed to evaluate potential predictors of ON symptoms and to compare questionnaires. As main results, OSCs had ahigher probability to result positive at ORTO-15 compared to non-OSCs. The prevalence among OSCs was 69.4% and 23.1% (using ORTO-15 with 40 and 35 cut-offs). Higher EHQ scores were reported among OSCs (p < 0.001). Potential predictors were mainly being an OSC or following food restrictions. Predictors varied using different cut-offsof ORTO-15 and EHQ. These results suggest the association between OSCs and ON symptoms. Some differences were found between ORTO-15 and EHQ. Further studies need to be performed to improve diagnostic tools.

Prevalence of gastro-oesophageal reflux symptoms: An Italian cross-sectional survey focusing on knowledge and attitudes towards lifestyle and nutrition.

INTRODUCTION: The gastro-oesophageal reflux disease (GERD) is a public health issue for its prevalence and association with low life quality and substantial costs. Since most of Italian data refer to over a decade ago, the aim was to provide an updated estimate of GERD symptoms prevalence. Knowledge about appropriate nutrition and behaviours in presence of GERD was assessed. Predictors for symptoms presence and knowledge were explored. METHODS: This study was an online cross-sectional survey that investigated socio-demographics, knowledge about nutrition/behaviours in case of GERD (Knowledge Score KS: percentage of right answers), nutrition/lifestyle attitudes. The questionnaire included the GerdQ to assess symptoms (presence if score ≥8). Adults resident in Italy were enrolled between June and August 2019 through convenience sampling on the major social networks (sample size = 559). Descriptive analyses were run. Multivariable regressions were performed to explore predictors of symptoms presence and KS. RESULTS: The 27.7% had GERD symptoms. Among them, 33.8% never received GERD information by their general practitioner (GP). Body mass index (P = .036), secondary education (P = .040) were associated with higher symptoms risk. Weekly exercise was associated with lower risk (P < .001). Median KS was 92% (IQR = 12). Sleeping on the left side, chocolate, citrus fruit, mint reported the lowest right answers percentages. None/basic education was negatively associated with KS (P < .001), being female (P = .004) and in a relationship (P = .012) positively. CONCLUSIONS: A high prevalence was reported, consistently with the worldwide increasing trend. Despite overall knowledge was high, specific gaps were found. GPs should improve communication and awareness campaigns targeted to less known aspects must be planned.

Predicting Length of Stay and Discharge Destination for Surgical Patients: A Cohort Study.

Discharge planning is important to prevent surgical site infections, reduce costs, and improve the hospitalization experience. The identification of early variables that can predict a longer-than-expected length of stay or the need for a discharge with additional needs can improve this process. A cohort study was conducted in the largest hospital of Northern Italy, collecting discharge records from January 2017 to January 2020 and pre-admission visits in the last three months. Socio-demographic and clinical data were collected. Linear and logistic regression models were fitted. The main outcomes were the length of stay (LOS) and discharge destination. The main predictors of a longer LOS were the need for additional care at discharge (+10.76 days), hospitalization from the emergency department (ED) (+5.21 days), and age (+0.04 days per year), accounting for clinical variables (p < 0.001 for all variables). Each year of age and hospitalization from the ED were associated with a higher probability of needing additional care at discharge (OR 1.02 and 1.77, respectively, p < 0.001). No additional findings came from pre-admission forms. Discharge difficulties seem to be related mainly to age and hospitalization procedures: those factors are probably masking underlying social risk factors that do not show up in patients with planned admissions.

Impact of a bundle on surgical site infections after hip arthroplasty: A cohort study in Italy (2012-2019).

BACKGROUND: Surgical site infections (SSIs) are an extremely serious complication of hip arthroplasty, estimated to affect up to nearly 3% of procedures. In Italy, SSIs are monitored through a national surveillance system (Sistema Nazionale Sorveglianza delle Infezioni del Sito Chirurgico, SNICh). Several studies suggest bundled interventions are effective in reducing SSI rates in orthopaedic surgery. MATERIALS AND METHODS: A bundled intervention was implemented in 2012 in 34 out of the 49 hospitals of the North-West of Italy participating in SNICh. A cohort study was conducted between January 1st, 2012 and December 31st, 2019 to evaluate the impact of the intervention on SSI rates after hip arthroplasty. The four elements of the bundle are: appropriate preoperative shower, preoperative hair removal, perioperative normothermia, antibiotic prophylaxis. Data on compliance with the bundle and the occurrence of infection were collected. RESULTS: In total, 18,791 procedures were included in the study. Full bundle compliance was achieved in 27.9% of procedures. The percentage of fully compliant procedures significantly increased over time from introduction of the bundled intervention (R2 0.799, p-value 0.003). Multivariable analysis found a significant association between full bundle compliance and reduced SSI rate, with a reduction of the odds of infection of 31% (95% CI 0.5-0.96; p 0.026). CONCLUSION: Results of this study support bundled interventions as an effective implementation strategy for infection prevention and control practices in hip replacement surgery. This simple bundle protocol could be easily implemented in settings with limited resources.

Prevalence of depressive symptoms among Italian medical students: The multicentre cross-sectional "PRIMES" study.

BACKGROUND: Four percent of the world's population suffers from depression, which is a major public health issue. Medical students are at risk, as their depressive symptoms (DS) prevalence is reported to be approximately 27% worldwide. Since few data on Italian medical students exist, this study aimed to estimate their DS prevalence and assess risk and protective factors. METHODS: The PRIMES was a multicentre cross-sectional study performed in 12 Italian medical schools. Questionnaires were self-reported and included 30 sociodemographic items and the Beck Depression Inventory-II (BDI-II). The primary outcome was the presence of DS (BDI-II score≥14). The main analyses were chi-squared tests and multivariable logistic regressions with a p-value<0.05 considered significant. RESULTS: The number of collected questionnaires was 2,513 (117 BDI-II incomplete). Females accounted for 61.3% of the respondents, and the median age was 22 years (IQR = 4). The prevalence of DS was 29.5%. Specifically, 14.0% had mild depression, 11.1% had moderate depression, and 4.5% had severe depression. The main risk factors for DS were age, being female, bisexual/asexual orientation, living with partner/housemates, poor economic status (worsened by living far from home), less than 90 min of weekly exercise, relatives with psychiatric disorders, personal chronic disease, judging medical school choice negatively, unsatisfying friendships with classmates, competitive and hostile climate among classmates, thinking that medical school hinders specific activities and being worried about not measuring up to the profession. Protective factors included family cohesion, hobbies, intellectual curiosity as a career motivation and no worries about the future. CONCLUSION: Italian medical students are at high risk of reporting DS, similar to the global population of medical students'. Medical schools must make efforts to implement preventive and treatment interventions by offering counselling and working on modifiable factors, such as lifestyle and learning climate.

Multi-port versus single-port cholecystectomy: results of a multi-centre, randomised controlled trial (MUSIC trial).

BACKGROUND: Single-port laparoscopic surgery as an alternative to conventional laparoscopic cholecystectomy for benign disease has not yet been accepted as a standard procedure. The aim of the multi-port versus single-port cholecystectomy trial was to compare morbidity rates after single-access (SPC) and standard laparoscopy (MPC). METHODS: This non-inferiority phase 3 trial was conducted at 20 hospital surgical departments in six countries. At each centre, patients were randomly assigned to undergo either SPC or MPC. The primary outcome was overall morbidity within 60 days after surgery. Analysis was by intention to treat. The study was registered with ClinicalTrials.gov (NCT01104727). RESULTS: The study was conducted between April 2011 and May 2015. A total of 600 patients were randomly assigned to receive either SPC (n = 297) or MPC (n = 303) and were eligible for data analysis. Postsurgical complications within 60 days were recorded in 13 patients (4.7 %) in the SPC group and in 16 (6.1 %) in the MPC group (P = 0.468); however, single-access procedures took longer [70 min (range 25-265) vs. 55 min (range 22-185); P < 0.001]. There were no significant differences in hospital length of stay or pain VAS scores between the two groups. An incisional hernia developed within 1 year in six patients in the SPC group and in three in the MPC group (P = 0.331). Patients were more satisfied with aesthetic results after SPC, whereas surgeons rated the aesthetic results higher after MPC. No difference in quality of life scores, as measured by the gastrointestinal quality of life index at 60 days after surgery, was observed between the two groups. CONCLUSIONS: In selected patients undergoing cholecystectomy for benign gallbladder disease, SPC is non-inferior to MPC in terms of safety but it entails a longer operative time. Possible concerns about a higher risk of incisional hernia following SPC do not appear to be justified. Patient satisfaction with aesthetic results was greater after SPC than after MPC.

Laparoscopic approach to acute abdomen from the Consensus Development Conference of the Società Italiana di Chirurgia Endoscopica e nuove tecnologie (SICE), Associazione Chirurghi Ospedalieri Italiani (ACOI), Società Italiana di Chirurgia (SIC), Società Italiana di Chirurgia d'Urgenza e del Trauma (SICUT), Società Italiana di Chirurgia nell'Ospedalità Privata (SICOP), and the European Association for Endoscopic Surgery (EAES).

BACKGROUND: In January 2010, the SICE (Italian Society of Endoscopic Surgery), under the auspices of the EAES, decided to revisit the clinical recommendations for the role of laparoscopy in abdominal emergencies in adults, with the primary intent being to update the 2006 EAES indications and supplement the existing guidelines on specific diseases. METHODS: Other Italian surgical societies were invited into the Consensus to form a panel of 12 expert surgeons. In order to get a multidisciplinary panel, other stakeholders involved in abdominal emergencies were invited along with a patient's association. In November 2010, the panel met in Rome to discuss each chapter according to the Delphi method, producing key statements with a grade of recommendations followed by commentary to explain the rationale and the level of evidence behind the statements. Thereafter, the statements were presented to the Annual Congress of the EAES in June 2011. RESULTS: A thorough literature review was necessary to assess whether the recommendations issued in 2006 are still current. In many cases new studies allowed us to better clarify some issues (such as for diverticulitis, small bowel obstruction, pancreatitis, hernias, trauma), to confirm the key role of laparoscopy (such as for cholecystitis, gynecological disorders, nonspecific abdominal pain, appendicitis), but occasionally previous strong recommendations have to be challenged after review of recent research (such as for perforated peptic ulcer). CONCLUSIONS: Every surgeon has to develop his or her own approach, taking into account the clinical situation, her/his proficiency (and the experience of the team) with the various techniques, and the specific organizational setting in which she/he is working. This guideline has been developed bearing in mind that every surgeon could use the data reported to support her/his judgment.

Diffusion of laparoscopic appendectomies in Italy: a national audit.

A national audit focused on laparoscopic appendectomy was promoted by the Italian Association of Hospital Surgeons (ACOI). Four-hundred and sixty surgical practices received an e-mail questionnaire. Data concerning epidemiology, timetable, surgeon's age, selection of patients, laparotomic conversion, behaviour in the case of a normal appendix, and technical aspects were investigated. The response rate was 51.7%. The median number of appendectomies performed is 50-100 each year in a surgery ward. Laparoscopic operations are very common (93%), but mostly performed in less than 50% of the observed cases. There is no significant difference between the number of operations during the day vs. at night, and they are performed by a limited (<30%) group of surgeons, equally composed of physicians aged above and below 40. The majority of surgeons adopt an "all comers" policy regarding laparoscopic appendectomy, including selected older patients (>70 years old). There are no standard indications for conversion, while the behaviour in the presence of a normal appendix is generally removal. Even if laparoscopic appendectomy is not yet considered a gold standard, it is widely diffused in Italy, and the audit's data show different behaviours between subgroups.
