Healthcare-associated infections (HAIs) represent a major threat in Europe. Infection prevention and control (IPC) measures are crucial to lower their occurrence, as well as antimicrobial stewardship to ensure appropriate use of antibiotics. Starting from Italian national data, this study aimed at: (i) describing IPC indicators, prevalence of HAIs, antimicrobial use and appropriateness of antibiotic use in Italy; (ii) estimating effects of IPC variables on HAI prevalence and on the proportion of antibiotics without specific reason.

Introduction: Residents of long-term care facilities (LTCFs) are a population at high risk of developing severe healthcare associated infections (HAIs). In the assessment of HAIs in acute-care hospitals, selection bias can occur due to cases being over-represented: patients developing HAIs usually have longer lengths of stays compared to controls, and therefore have an increased probability of being sampled in PPS, leading to an overestimation of HAI prevalence. Our hypothesis was that in LTCFs, the opposite may occur: residents developing HAIs either may have a greater chance of being transferred to acute-care facilities or of dying, and therefore could be under-represented in PPS, leading to an underestimation of HAI prevalence.

Surgical site infections (SSIs) have been associated with increases in terms of costs, hospital stay, morbidity, and mortality. We aimed to assess trends in SSIs monitored through 10 years of surveillance activities in our region, and to describe mortality attributable to SSIs in the two most frequently monitored surgical procedures: colorectal surgery and hip arthroplasty. A retrospective cohort study was conducted among the 42 hospitals participating in the surveillance network of our region in northern Italy.

Objective: The Italian National Action Plan to contrast AMR identified among its objectives the development and implementation of a national Healthcare-Associated Infection (HAI) surveillance system based on European Centre for Disease Prevention and Control (ECDC) indications, through point prevalence surveys (PPS) of HAIs and antibiotic use in acute-care hospitals and long-term care facilities (LTCFs). We aimed to assess feasibility and appropriateness of proposed tools for a national surveillance system of HAIs and antibiotic use in LTCFs.

Study Design: Point prevalence survey.

Background And Aims: Long-term care facilities (LTCFs) have been severely impacted by COVID-19, with a disproportionate amount of SARS-CoV-2 infections and related deaths occurring among residents.

Methods: This study is part of an ongoing multicenter, prospective cohort study conducted among healthcare workers (HCWs) and residents of 13 LTCFs in Northern Italy designed to evaluate SARS-CoV-2 specific immunoglobulin class G (IgG) titers before and following vaccination with Pfizer/BNT162b2 SARS-CoV-2 mRNA vaccine (two doses of vaccine, 21 days apart). Serum samples were obtained from participants (t0) before vaccination, and (t1) 2 weeks after and analyzed to determine anti-S1 IgG antibodies.

Article Synopsis
  • Long-term care facilities in Northern Italy faced significant challenges during COVID-19, prompting a study on antibody responses to the Pfizer/BNT162b2 vaccine among residents and healthcare workers at 13 facilities.
  • Serum samples were collected at three time points: before vaccination, two weeks post-vaccination, and nine months later, revealing the highest IgG antibody levels two weeks after vaccination, with a notable decrease by nine months.
  • The only strong predictor for developing and maintaining adequate antibody responses was prior COVID-19 infection, highlighting the importance of understanding both vaccination effects and individual factors on antibody levels.

The debate on vaccination mandate was fuelled over the past two years by the COVID-19 pandemic. This study aimed at overviewing vaccination strategies and corresponding vaccine coverages for childhood vaccinations before the pandemic and for SARS-CoV-2 in high-income countries. A qualitative comparison was also performed between the two contexts: unlike for childhood vaccinations, only one European country (Austria) imposed generalised COVID-19 mandates, most countries preferring targeted mandates for higher-risk categories (Italy, Greece) or workers in key public services (Finland, Australia, New Zealand, UK, Germany).

Upper-respiratory-tract infections (URTIs) are among the main causes of antibiotic prescriptions in pediatric patients. Over one-third of all antibiotic prescriptions for URTIs in children are estimated to be inappropriate, as the majority of URTIs are caused by viral agents. Several strategies, including clinical scoring algorithms and different point-of-care tests (POCTs) have been developed to help discriminate bacterial from viral URTIs in the outpatient clinical setting.
