Healthcare-associated infections and antimicrobial use in acute care hospitals: a point prevalence survey in Lombardy, Italy, in 2022.

BACKGROUND: Healthcare-Associated Infections (HAIs) are a global public health issue, representing a significant burden of disease that leads to prolonged hospital stays, inappropriate use of antimicrobial drugs, intricately linked to the development of resistant microorganisms, and higher costs for healthcare systems. The study aimed to measure the prevalence of HAIs, the use of antimicrobials, and assess healthcare- and patient-related risk factors, to help identify key intervention points for effectively reducing the burden of HAIs. METHODS: A total of 28 acute care hospitals in the Lombardy region, Northern Italy, participated in the third European Point Prevalence Survey (PPS-3) coordinated by ECDC for the surveillance of HAIs in acute care hospitals (Protocol 6.0). RESULTS: HAIs were detected in 1,259 (10.1%, 95% CI 9.6-10.7%) out of 12,412 enrolled patients. 1,385 HAIs were reported (1.1 HAIs per patient on average). The most common types of HAIs were bloodstream infections (262 cases, 18.9%), urinary tract infections (237, 17.1%), SARS-CoV-2 infections (236, 17.0%), pneumonia and lower respiratory tract infections (231, 16.7%), and surgical site infections (152, 11.0%). Excluding SARS-CoV-2 infections, the overall prevalence of HAIs was 8.4% (95% CI 7.9-8.9%). HAIs were significantly more frequent in patients hospitalized in smaller hospitals and in intensive care units (ICUs), among males, advanced age, severe clinical condition and in patients using invasive medical devices. Overall, 5,225 patients (42.1%, 95% CI 41.3-43.0%) received systemic antimicrobial therapy. According to the WHO's AWaRe classification, the Access group accounted for 32.7% of total antibiotic consumption, while Watch and Reserve classes accounted for 57.0% and 5.9% respectively. From a microbiological perspective, investigations were conducted on only 64% of the HAIs, showing, however, a significant pattern of antibiotic resistance. CONCLUSIONS: The PPS-3 in Lombardy, involving data collection on HAIs and antimicrobial use in acute care hospitals, highlights the crucial need for a structured framework serving both as a valuable benchmark for individual hospitals and as a foundation to effectively channel interventions to the most critical areas, prioritizing future regional health policies to reduce the burden of HAIs.

Changing the stroke network during pandemic scenarios does not affect the management of patients with a positive Cincinnati prehospital stroke scale.

INTRODUCTION: Time plays a crucial role in the management of stroke, and changing the prehospital emergency network, altering the HUB and spoke relationship in pandemic scenarios, might have an impact on time to fibrinolysis or thrombectomy. The aim of this study was to evaluate the time-dependent stroke emergency network in Lombardy region (Italy) by comparing 2019 with 2020 and early 2021. Three parameters were investigated: (i) time of arrival of the first vehicle at the scene, (ii) overall duration of missions, and (iii) number of patients transported by emergency vehicles. METHODS: Data analysis process conducted using the SAS-AREU portal (SAS Institute, USA). RESULTS: The number of patients with a positive CPSS was similar among the different pandemic waves. Mission duration increased from a mean time (SD) of 52.9 (16.1) min in 2019 to 64.1 (19.7) in 2020 and 55.0 (16.8) in 2021. Time to first vehicle on scene increased to 15.7 (8.4) min in 2020 and 16.0 (7.0) in 2021 compared to 2019, 13.6 (7.2) (P < 0.05). The number of hospital with available stroke units decreased from 46 in 2019 to 10 during the first pandemic wave. CONCLUSIONS: The pandemic forced changes in the clinical mission of many hospitals by reducing the number of stroke units. Despite this, the organization of the emergency system allowed to identify strategic hospitals and thus avoid excessive transport time. The result was an adequate time for fibrinolysis/thrombectomy, in agreement with the guidelines. Coordinated management in emergency situations makes it possible to maintain service quality standards, despite the unfavorable scenario.

The Impact of the Coronavirus Disease 2019 Pandemic on Helicopter Emergency Medical Services.

The coronavirus disease 2019 pandemic has profoundly affected the Lombardy healthcare system. Although air transport of critical patients played a crucial role, there are still gaps in understanding how the pandemic impacted helicopter emergency medical services (HEMS). A retrospective observational analysis was performed using data from the regional emergency-urgency online portal. The investigation focused on patients airlifted by helicopter to the Lombardy emergency departments from January 1, 2019, to December 31, 2021. A total of 12,953 admissions to the emergency departments have been recorded (5,733 in 2019, 3,550 in 2020, and 3,670 in 2021). The monthly average of events changed significantly over the 3 years (2019 [477.7], 2020 [295.8], and 2021 [305.8]) (P < .001). Additionally, there was a notable increase in the percentage of severe cases with red triage codes in 2020 (28.9%) and 2021 (33.5%) compared with 2019 (19.9%). Moreover, the number of hospitalized patients increased in 2020 (39.9%) and 2021 (37.2%) compared with 2019 (27.7%). The HEMS documented a noteworthy decrease in mission numbers and an increase in patient clinical severity during the pandemic. Consequently, the HEMS might be allocated for specific roles in national pandemic plans during the alert phase activation, such as secondary transport between hospital facilities.

Primary care doctors retirements in the context of an ageing population in Italy.

Background: Ongoing shortages in primary care doctors/primary care paediatricians and increasing healthcare needs due to ageing of the population represent a great challenge for healthcare providers, managers, and policymakers. To support planning of primary healthcare resource allocation we analyzed the geographic distribution of primary care doctors/primary care paediatricians across Italian regions, accounting for area-specific number and age of the population. Additionally, we estimated the number of primary care doctors/primary care paediatricians expected to retire over the next 25 years, with a focus on the next five years. Study design: Ecological study. Methods: We gathered the list of Italian general practitioners and primary care paediatricians and combined them with the data from the National Federation of Medical Doctors, Surgeons and Dentists. Using data from the National Institutes of Statistics, we calculated the average number of patients per doctor for each region using the number of residents above and under 14 years of age for general practitioners and primary care paediatricians respectively. We also calculated the number of residents over-65 and over-75 years of age per general practitioner, as elderly patients typically have higher healthcare needs. Results: On average the number of patients per general practitioner was 1,447 (SD: 190), while for paediatricians it was 1,139 (SD: 241), with six regions above the threshold of 1,500 patients per general practitioner and only one region under the threshold of 880 patients per paediatrician. We estimated that on average 2,228 general practitioners and 444 paediatricians are going to retire each year for the next five years, reaching more than 70% among the current workforce for some southern regions. The number of elderly patients per general practitioner varies substantially between regions, with two regions having >15% more patients aged over 65 years compared to the expected number. Conclusions: over 65 years compared to the expected number. Conclusions. The study highlighted that some regions do not currently have the required primary care workforce, and the expec-ted retirements and the ageing of the population will exacerbate the pressure on the already over-stretched healthcare services. A response from healthcare administrations and policymakers is urgently required to allow equitable access to quality primary care across the country.

Impact of the Covid pandemic on timely cancer diagnosis across European healthcare settings: a scoping review.

Introduction: The COVID-19 pandemic presented unprecedented challenges to European healthcare systems. The study aimed to review the available evidence on the impact of the pandemic on the timely diagnosis of cancer across European countries. The primary objective was to examine changes in diagnostic pathways and stage at diagnosis during the pandemic, compared to the pre-pandemic period, across European countries, taking healthcare system characteristics and COVID-19 policies into account. Methods: We conducted a review of the impact of the pandemic on cancer diagnosis in Europe, analyzing primary studies from 2018 to 2023 using both quantitative and qualitative methods through searches in PubMed and Scopus databases. Study quality was assessed using the Mixed Methods Appraisal Tool. The main explanatory factors analyzed were grouped into two categories: Covid-policies (government responses, using the Oxford COVID-19 Government Response Tracker and its stringency index as key metrics) and healthcare characteristics (healthcare system models, expenditure and resources, including hospital beds and the ratio of medical doctors). Study design: Scoping review. Results: Overall, 127 papers were screened, 80 retrieved for full-text evaluation and 50 articles were included in the review. The studies encompassed a total of 509,753 patients from 17 European countries. The pandemic period was characterised by worse process and outcome measures for all examined cancers, except for lung cancer, compared to the pre-pandemic period. Group-ing countries based on government actions and policy responses (stringency index) did not show any differences in timely cancer diagnosis. Countries with lower healthcare expenditure (per capita expenditure <2,000 euros) or lower investments in prevention reported more cancer diagnostic delays during the pandemic. Countries with >20% of General Practitioners over the total number of physicians and with more hospital beds per population experienced fewer diagnostic delays during the pandemic. Conclusions: Overall, the review suggests that diagnostic pathways and cancer stage at diagnosis during the COVID-19 pandemic varied across Europe, with countries' healthcare expenditure, investments in prevention, the proportion of General Practitioners and the number of hospital beds per population possibly playing a role. This analysis can inform healthcare policies aimed at addressing post-pandemic challenges and formulating resilience plans for future emergencies.

Variations in avoidable hospital admissions and emergency visits by primary care characteristics: an ecological study in Italy.

Background: Primary healthcare plays a central role in providing preventive care, managing chronic conditions and reducing inappropriate emergency presentations. The study aimed at providing population-level evidence on the correlation between the characteristics of primary healthcare across Italian regions and health outcomes included in the National Programs Outcomes of the National Agency for Regional Healthcare Services. Study Design: Ecological study. Methods: We analysed healthcare data from the National Agency for Regional Healthcare Services, the public lists of primary care doctors and the National Federation of Surgeons and Dentists and the National Institutes of Statistics referring to the 20 Italian regions. Pearson's correlation and Spearman's correlation were used to assess the relationships between primary healthcare characteristics and health outcomes. Results: Overall, across all Italian regions each general practitioner had on average 1447 patients and was 57.5 years old. The study found positive correlations between the number of patients per general practitioner and non-urgent Emergency Department visits among adult patients (Pearson's r = 0.58, p = 0.008), the number of residents aged 65+ per general practitioner and the rate of chronic obstructive pulmonary disease admissions (Pearson's r = 0.49, p = 0.029), and the age of general practitioners and lower-extremity amputations in diabetes patients (Pearson's r = 0.56, p = 0.011). A negative correlation was observed between the age of general practitioners and urinary tract infection admissions (Pearson's r = -0.76; p < 0.001). A non-linear negative correlation was found between the age of general practitioners and chronic obstructive pulmonary disease admissions (Spearman's ρ = -0.46, p = 0.041). Conclusions: The findings emphasise the importance of guaranteeing sufficient numbers of primary healthcare physicians to meet patients' needs, and for limiting avoidable hospitalisations and emergency presentations. General practitioners' age might also influence the provision of care, but more research is needed on possible mechanisms.

Enhancing Physicians' Autonomy through Practical Trainings.

Background: In medical emergencies adherence to standardized clinical protocols is crucial to ensure a better outcome for patients. Newly qualified physicians may play several roles in serving the National Health Service (substituting general practitioners, on-call duty, working in emergency rooms, etc.) in Italy. In these situations, the physician may have to manage critical patients autonomously. Moreover, newly qualified physicians may show a considerable deficiency in routine medical activities. In fact, many universities do not provide a practical simulation training programme, which is why a substantial number of students only face clinical emergencies when they start working after graduation. Study design: A cross-sectional study was performed by engaging medical doctors. Both experienced physicians and newly licensed physicians (graduated less than 24 months ago) were included in the study. Methods: A questionnaire was distributed to each participant during SIMED's Courses from June 2021 to December 2022. The questionnaire consisted of two sections. The first one analyzed participation in standardized practical courses on medical emer-gencies (Basic Life Support, Advanced Cardiac Life Support, International Trauma Life Support and a course on Advanced Airway Management). The second section analyzed the perceived autonomy of health professionals in the management of five different work settings, using a 5-point likert scale. Results: 2,168 questionnaires were analyzed, of which 68.7% were from newly qualified doctors and 31.3% from more experienced doctors. The highest rate of physicians who undertook training courses was achieved for the basic life support course (77.5%) and the lowest rate for the advanced trauma course (15.9%). Physicians perceive themselves the highest autonomy in Primary Care setting (63.1%), while in the Emergency Department they perceive themselves with less autonomy (24.0%). In the analyzed sample, experienced physicians show a higher percentage of autonomy than newly qualified doctors (31.4% vs 8.1%) in all scenarios.

The role of pharmacies in the implementation of vaccination cover- age in Italy. Insights from the preliminary data of the Lombardy Region.

Introduction: The administration of vaccines in pharmacies was not allowed in Italy until 2021. During the COVID-19 pandemic, legislative innovations were introduced that now allow qualified pharmacists to administer anti-flu and anti-COVID-19 vaccines after completing specific training. Methods: The article provides an overview of legislation concerning vaccinations in Italian pharmacies, followed by a description of the vaccinations carried out by pharmacies participating in the regional vaccination campaign from 2021 to 2023. The study relies on data extracted from the Lombardy Region's database on vaccine administration in pharmacies. Furthermore, innovative vaccination practices from the Marche Region were also taken into consideration. Study Design: Observational Study. Results: Lombardy became the Italian pioneer region in extensively incorporating pharmacy-based vaccinations, starting in 2021. This initiative reached its zenith with 46% of anti-COVID vaccines and 17% of flu vaccines administered within the first six weeks of the autumn 2023 campaign. Pharmacies played a crucial role in meeting the targets outlined in the Italian National Vaccine Prevention Plan for 2023-25. As part of an experimental program, the Marche Region has further expanded pharmacy-based vaccinations, now including anti-zoster and anti-pneumococcus vaccines for the 2023-24 campaign. Conclusions: The promising outcomes observed in Lombardy and the ongoing experimental efforts in the Marche are encouraging steps toward achieving vaccination coverage targets, albeit still falling below the objectives set by the National Vaccination Plan for 2023-25. The widespread presence of pharmacies throughout the territory makes them well-suited as support structures for vaccination campaigns, especially in reaching the adult, the elderly, and the vulnerable populations.

The contribution of the private healthcare sector during the COVID-19 pandemic: the experience of the Lombardy Region in Northern Italy.

Introduction: In Lombardy, the first European region hit by the COVID-19 pandemic, for decades the regional public healthcare service has followed a mixed delivery model with extensive involvement of private accredited providers. The study aimed at examining the role of the private sector in delivering healthcare services (diagnosis, hospitalization, and vaccination) during the pandemic. Study design: Healthcare system study. Methods: We analysed regional healthcare data referring to the period from March 2020 onwards to assess the availability of acute care and intensive care hospital beds, SARS-CoV-2 tests, and COVID-19 vaccinations. We specifically examined healthcare offered by private accredited providers within the region. Results: Of the 12,306 converted beds for COVID-19 treatment, 4,975 (40%) were in accredited private hospitals. Intensive care beds increased by 95%, reaching 1,755, with 484 (28%) in accredited private hospitals. Since the pandemic onset, 28.9 million (62%) of SARS-CoV-2 tests were conducted by private accredited facilities including pharmacies. Private sector actively contributed to the COVID-19 vaccination campaign administering over 2.6 million doses in 2021, enhancing vaccination capacity to its peak. Conclusions: The longstanding relationship between the public and private sectors within the Lombardy regional healthcare service facilitated a rapid increase in hospital bed capacity, the upscaling of SARS-CoV-2 testing capacity, and the achievement of vaccination goals to address the COVID-19 emergency. Therefore, alongside a robust and adequately funded public healthcare service, the private sector serves as an asset to enhance the resilience of healthcare systems, in line with WHO indications.

Quality of hospital care and clinical outcomes: a comparison between the Lombardy Region and the Italian national data.

Background: Improving the quality and effectiveness of healthcare is a key priority in health policy. The emergence of the COVID-19 pandemic has exerted considerable pressure on hospital networks, requiring unprecedented reorganization and restructuring actions. This study analyzed data from the Italian National Outcomes Program to compare some volumes and outcomes of public and private accredited hospitals in the Lombardy Region with national data. Study design: Observational study. Methods: A thorough examination of hospital outcomes between 2019 and 2021 was conducted, considering 45 volume indicators and 48 process and outcome indicators, comparing Lombardy with other Italian regions and public versus private accredited hospitals. Results: In 2020, Italy and Lombardy experienced a considerable reduction in overall hospital admissions, with Lombardy showing a deeper decline (21.3% compared with 16.0% in Italy). In 2021, both experienced a partial recovery, especially marked in the Lombardy region (+7.3%, compared with national data). Focusing specifically on the private sector in Lombardy, a recovery of +9.3% in hospitalization was observed. In the analysis of clinical outcomes, Lombardy outperformed the national average for 63% of the indicators in 2020 and 83.3% in 2021. Conclusions: The study shows the continuing decline in volumes compared to 2019 (pre-COVID), the excellent performance of hospitals in Lombardy and a relevant contribution for the volumes and the quality of outcomes of private accredited hospitals.

COVID-19 Immunity in the Cohort of IRCCS San Raffaele Hospital Employees after BNT162b2 Vaccination: A Retrospective Observational Study.

Introduction: The COVID-19 pandemic represents the most severe health and socioeconomic crisis of our century. It began with the first reports in China, in the Wuhan region in December 2019, and quickly spread worldwide, causing a new Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2). Among the population most at risk of infection and developing severe forms of the disease are the elderly and healthcare workers, who are more exposed to infected individuals. On December 11, 2020, the Food and Drug Administration approved the emergency use of the BNT162b2 vaccine, the first mRNA vaccine in history. Since then, the total number of vaccine doses administered has exceeded 12 billion. Italy was the first European country to be affected by the pandemic, recording the highest number of total COVID-19 cases (25,695,311) and, after the first 70 days, had the highest crude mortality rate (141.0 per 100,000). In this study, we analyze the rate of SARS-CoV-2 infection among healthcare workers at the San Raffaele Scientific Institute in Milan before and after receiving the BNT162b2 vaccine. Study design: Retrospective observational cohort study. Methods: The study analyzed the immunization status of 858 employees of the San Raffaele Scientific Institute in Milan, including doctors, healthcare workers, and administrative staff. The analysis is based on previous studies on the same cohort and is integrated with extrapolation and additional analysis of data from the Preventive Medicine Service's Biobank dataset of the same hospital to estimate the infection rate, duration of the disease, and antibody levels recorded in the personnel before and after receiving the double BNT162b2 vaccination. Results: The analysis confirms the positive impact achieved by the introduction of mRNA vaccination in reducing the SARS-CoV-2 infection rate and increasing antibody levels in healthcare workers. Although the BNT162b2 vaccination may not provide complete protection against SARS-CoV-2, it appears to be able to reduce the number of infections, particularly the more severe and symptomatic forms often detected in individuals with various risk factors and comorbidities, making them more vulnerable. Healthcare workers, who have extensive contact with patients and record the greatest decrease in the infection rates, represent the population that receives the most benefit from vaccination. Conclusions: The evidence suggests that vaccinations are essential in protecting high-risk groups, such as healthcare workers, from SARS-CoV-2 infection. Providing adequate vaccination coverage to healthcare workers limits the spread of infections and decreases the severity of disease manifestations, while also reducing their duration.

Immune-related adverse events and disease outcomes after the third dose of SARS-CoV-2 mRNA-BNT162b2 vaccine in cancer patients receiving immune checkpoint inhibitors.

BACKGROUND: The clinical implications of the third dose of coronavirus disease 2019 (COVID-19) vaccines in patients receiving immune checkpoint inhibitors are currently unknown. We performed a prospective analysis of the Vax-On-Third study to investigate the effects of antibody response on immune-related adverse events (irAEs) and disease outcomes. METHODS: Recipients of the booster dose of SARS-CoV-2 mRNA-BNT162b2 vaccine who had received at least one course of an anti-PD-1/PD-L1 treatment before vaccination for an advanced solid malignancy were eligible. RESULTS: The current analysis included 56 patients with metastatic disease (median age: 66 years; male: 71%), most of whom had a lung cancer diagnosis and were being treated with pembrolizumab- or nivolumab-based regimens. The optimal cut-point antibody titer of 486 BAU/mL allowed a dichotomization of recipients into low-responders (Low-R, < 486 BAU/mL) or high-responders (High-R, ≥ 486 BAU/mL). After a median follow-up time of 226 days, 21.4% of patients experienced moderate to severe irAEs without any recrudescence of immune toxicities preceding the booster dose. The frequencies of irAE before and after the third dose did not differ, but an increase in the cumulative incidence of immuno-related thyroiditis was observed within the High-R subgroup. On multivariate analysis, an enhanced humoral response correlated with a better outcome in terms of durable clinical benefit, which resulted in a significant reduction in the risk of disease control loss but not mortality. CONCLUSIONS: Our findings would strengthen the recommendation not to change anti-PD-1/PD-L1 treatment plans based on current or future immunization schedules, implying that all these patients should be closely monitored.

Grandparenting during pandemic times: pros and cons for mental health.

BACKGROUND: The COVID-19 pandemic and associated lockdown measures posed an unprecedented challenge to the crucial role of grandparenting in family-oriented cultures, such as Italy. Reduced contact with grandchildren during this period potentially threatened grandparents' mental health and well-being. METHODS: We analysed data from the LOckdown and lifeSTyles in Lombardia cross-sectional study conducted in November 2020. The study included a representative sample of 4400 older adults from Lombardy, Italy, of which 1289 provided childcare to their grandchildren. RESULTS: A decrease in self-reported grandparenting was associated with an increased likelihood of experiencing depressive symptoms among grandparents (OR 1.50, 95% CI 1.01-2.24). Conversely, an increase in grandparenting was linked to poorer sleep quality (OR 11.67, 95% CI 5.88-23.17) and reduced sleep quantity (OR 2.53, 95% CI 1.45-4.41). CONCLUSIONS: Despite the barriers posed by the pandemic, grandparenting played a beneficial role in maintaining the mental health and well-being of older adults. However, it is crucial to recognise specific vulnerabilities, such as gender, feelings of hopelessness and overcrowding, which can have detrimental effects during and beyond emergency situations. Careful attention to these factors is essential for developing targeted support systems and interventions aimed at safeguarding the mental health of older adults and enhancing their resilience in crises.

Health and social home services among community-dwelling older people during COVID-19: Results from the cross-sectional LOST in Lombardia project.

BACKGROUND: Few studies have focused on changes in health and social services access due to the COVID-19 pandemic. We aimed to describe changes in the use of selected health and social home services due to the pandemic and to investigate potential associated factors, including socio-demographic characteristics, number of chronic diseases and mental health indicators, among older Italian individuals. METHODS: We analysed data from the LOST in Lombardia cross-sectional study conducted in November 2020 on a large representative sample of 4400 individuals aged ⩾65 years. To identify potential factors associated with the increased use of three selected health and social home services, we estimated odds ratios (OR) and confidence intervals (CI) using multivariable logistic regression models. RESULTS: Compared to the year before, 5.0% of older adults increased help from domestic workers (vs. 6.9% reducing) during the pandemic, 4.4% increased help from non-familiar caregivers (vs. 1.3% decreasing) and 4.7% increased medical home visits (vs. 1.0% decreasing). An increase in the use of these services was more frequent among participants with co-morbidities (p for trend <0.001), especially with diabetes (for caregivers: OR=12.2, 95% CI 6.0-24.8), and worse mental health (for caregivers and for those with a GAD-2 score ⩾3 vs. <3: OR=10.6, 95% CI 5.8-19.4). Conversely, people living in more crowded households less frequently increased health and social services use during the pandemic. CONCLUSIONS: Our results should inform targeted interventions for the identified vulnerable groups to close the gap in health and social inequities.

Training needs assessment of European frontline health care workers on vaccinology and vaccine acceptance: a systematic review.

BACKGROUND: The issue of reluctance towards vaccination is becoming more worrisome. Health care workers (HCWs) are the primary point of contact with individuals who make decisions about vaccination. Therefore, it is crucial that HCWs receive sufficient training and periodic updates. The main objective of this systematic review is to evaluate the HCWs' training needs in vaccination and vaccine uptake. METHODS: In February 2022, a search was conducted on MEDLINE, Scopus and Google Scholar databases. The search included papers written in English, Italian, Portuguese, Spanish, French and Romanian, with a publication date ranging from 1 January 2011 to 24 February 2022 and conducted in Europe. To assess the methodological quality of the papers, the Appraisal tool for Cross-Sectional Studies was utilized. RESULTS: The search of scientific literature yielded 640 outcomes on PubMed, 556 on Scopus and 15 on Google Scholar, for a total of 1211 records. After eliminating duplicates, screening titles and abstracts and evaluating the full text of the articles, only 25 of them were found suitable for inclusion. The studies' overall quality ranged from moderate to good. The majority of the research emphasized the need for improved knowledge of vaccine-preventable diseases, vaccine efficacy, immunization schedules and vaccine adverse effects. CONCLUSIONS: It is vital to prioritize educational programmes on vaccinology and vaccine hesitancy for HCWs, with the objective of improving their knowledge, awareness and attitudes. Addressing the diversity of educational backgrounds, roles and training requirements of HCWs involved in vaccination across Europe is a critical issue that must be tackled for future initiatives.

Cardiopulmonary resuscitation missed by bystanders: Collateral damage of coronavirus disease 2019.

OBJECTIVE: The coronavirus disease 2019 (COVID-19) pandemic changed the time-dependent cardiac arrest network. This study aims to understand whether the rescue standards of cardiopulmonary resuscitation (CPR) and out-of-hospital cardiac arrest (OHCA) were handled differently during pandemic compared to the previous year. METHODS: Data for the years 2019 and 2020 were provided by the records of the Lombardy office of the Regional Agency for Emergency and Urgency. We analysed where the cardiac arrest occurred, when CPR started and whether the bystanders used public access to defibrillation (PAD). RESULTS: During 2020, there was a reduction in CPRs performed by bystanders (odds ratio [OR] = 0.936 [95% confidence interval (CI95% ) 0.882-0.993], p = .029) and in the return of spontaneous circulation (ROSC) (OR = 0.621 [CI95% 0.563-0.685], p < .0001), while there was no significant reduction in the use of PAD. Analysing only March, the period of the first wave in Lombardy, the comparison shows a reduction in bystanders CPRs (OR = 0.727 [CI95% 0.602-0.877], p = .0008), use of PAD (OR = 0.441 [CI95% 0.272-0.716], p = .0009) and in ROSC (OR = 0.179 [CI95% 0.124-0.257], p < .0001). These phenomena could be influenced by the different settings in which the OHCAs occurred; in fact, those that occurred in public places with a mandatory PAD were strongly reduced (OR = 0.49 [CI95% , 0.44-0.55], p < .0001). CONCLUSIONS: COVID-19 had a profound impact on the time-dependant OHCA network. During the first pandemic wave, CPR and PAD used by bystanders decreased. The different contexts in which OHCAs occurred may partially explain these differences.

Daily patterns of physical activity, sedentary behavior, and prevalent and incident depression-The Maastricht Study.

This study aims to compare the accelerometer-measured daily patterns of PA and sedentary behavior among participants with and without prevalent/incident depressive symptoms. We used data from 5582 individuals in The Maastricht Study (59.9 ± 8.6 years, 50.3% women). Daily patterns of sedentary time, light-intensity physical activity (LiPA), moderate-to-vigorous physical activity (MVPA), and sit-to-stand transitions were objectively measured at baseline with the activPAL3 activity monitor. Depressive symptoms were assessed using the 9-item Patient Health Questionnaire, both at baseline and annually (median follow-up: 5.1 years). General linear models were used to compare patterns of physical activity and sedentary behavior between those with and without prevalent/incident depressive symptoms. Participants with prevalent depressive symptoms had significantly more sedentary time (18.6 min/day) and lower LiPA (26.8 min/day) and MVPA (4.8 min/day) than participants without depressive symptoms. Considering the daily patterns, participants with prevalent depressive symptoms had significantly more sedentary time early in the afternoon (12:00-18:00), early evening (18:00-21:00), and during the night (00:00-03:00), less time in LiPA in all periods between 09:00-21.00 and less MVPA in the morning (09:00:12:00), early afternoon (12:00-15:00), and evening (18:00-21:00), than those without. Similar differences in activity and sedentary behavior patterns between those and without incident depressive symptoms were observed albeit the differences were smaller. Overall, we did not find specific time slots particularly associated with both prevalent and incident depressive symptoms. These findings may indicate that less sedentary time and more intense PA can be important targets for the prevention of depression irrespective of the timing of the day.

After Action Reviews of COVID-19 response: Case study of a large tertiary care hospital in Italy.

BACKGROUND: After-Action Reviews (AARs) are management tools used to evaluate the response to public health emergencies at the national and subnational level. Aim of this study is to apply available AAR models to assess and critically appraise COVID-19 response of San Raffaele Scientific Institute, a large university hospital in Milan, Italy. METHODS: We designed an AAR based on the key-informant interview format, following the methodology proposed by the 2019 World Health Organization Guidance for AAR. After systematic assessment of the hospital reorganization, we conducted 36 semi-structured interviews to professionals with executive, clinical, technical and administrative roles. We designed an ad-hoc questionnaire exploring four areas: (i) staff management; (ii) logistics and supplies; (iii) COVID-19 diagnosis and clinical management; (iv) communication. RESULTS: Overall, the hospital response was evaluated as effective and sufficiently prompt. Participants stressed the relevance of: (i) strong governance and coordination; (ii) readiness and availability of healthcare personnel; (iii) definition of a model of care based on a multidisciplinary approach. Challenges were reported for communication management and staff training. CONCLUSIONS: This study is one of the first applications of the AAR to the COVID-19 response in hospital settings, which can be successfully adapted or scaled up to other settings in order to implement preparedness strategies for future public health emergencies.

Early predictors of clinical outcomes of COVID-19 outbreak in Milan, Italy.

BACKGROUND: National health-system hospitals of Lombardy faced a heavy burden of admissions for acute respiratory distress syndromes associated with coronavirus disease (COVID-19). Data on patients of European origin affected by COVID-19 are limited. METHODS: All consecutive patients aged ≥18 years, coming from North-East of Milan's province and admitted at San Raffaele Hospital with COVID-19, between February 25th and March 24th, were reported, all patients were followed for at least one month. Clinical and radiological features at admission and predictors of clinical outcomes were evaluated. RESULTS: Of the 500 patients admitted to the Emergency Unit, 410 patients were hospitalized and analyzed: median age was 65 (IQR 56-75) years, and the majority of patients were males (72.9%). Median (IQR) days from COVID-19 symptoms onset was 8 (5-11) days. At hospital admission, fever (≥ 37.5 °C) was present in 67.5% of patients. Median oxygen saturation (SpO2) was 93% (range 60-99), with median PaO2/FiO2 ratio, 267 (IQR 184-314). Median Radiographic Assessment of Lung Edema (RALE) score was 9 (IQR 4-16). More than half of the patients (56.3%) had comorbidities, with hypertension, coronary heart disease, diabetes and chronic kidney failure being the most common. The probability of overall survival at day 28 was 66%. Multivariable analysis showed older age, coronary artery disease, cancer, low lymphocyte count and high RALE score as factors independently associated with an increased risk of mortality. CONCLUSION: In a large cohort of COVID-19 patients of European origin, main risk factors for mortality were older age, comorbidities, low lymphocyte count and high RALE.

Living near waterbodies as a proxy of cyanobacteria exposure and risk of amyotrophic lateral sclerosis: a population based case-control study.

BACKGROUND: Epidemiological studies highlighted the possibility that exposure to cyanotoxins leads to the development of the neurodegenerative disease amyotrophic lateral sclerosis (ALS). METHODS: We devised a population-based case-control study in two Italian populations. We used residential proximity of the residence to water bodies as a measure of possible exposure to cyanotoxins. RESULTS: Based on 703 newly-diagnosed ALS cases and 2737 controls, we calculated an ALS odds ratio (OR) of 1.41 (95% CI: 0.72-2.74) for current residence in the vicinity of water bodies, and a slightly lower estimate for historical residence (OR: 1.31; 95% CI: 0.57-2.99). Subjects <65 years and people living in the Northern Italy province of Modena had higher ORs, especially when historical residence was considered. CONCLUSIONS: Overall, despite some risk of bias due to exposure misclassification and unmeasured confounding, our results appear to support the hypothesis that cyanotoxin exposure may increase ALS risk.
