Inverse probability weighting leads to more accurate incidence estimates for healthcare-associated infections in intensive care units - results from two national surveillance systems.

Background: Two main approaches are employed to monitor healthcare-associated infections (HAIs): longitudinal surveillance, which allows the measurement of incidence rates, and point prevalence surveys (PPSs). PPSs are less time-consuming; however, they are affected by length-biased sampling, which can be corrected through inverse probability weighting. We assessed the accuracy of this method by analysing data from two Italian national surveillance systems.

Late-onset capsular bag distension syndrome 33 years after cataract surgery.

Purpose: Describe the clinical features and management of this uncommon case of late-onset Capsular bag distension syndrome that occurred 33 years after cataract surgery.

Observation: An 87-year-old male was referred to our clinic complaining of blurred and gradual, painless reduction in vision in his left eye over the past year. A complete ophthalmological examination, Ultrasound biomicroscopy (UBM), anterior segment optical coherence tomography (AS-OCT), and optical biometry were performed to confirm the diagnosis.

Italian National Surveillance of Alcohol-Based Hand Rub Consumption in a Healthcare Setting-A Three-Year Analysis: 2020-2022.

Hand hygiene (HH) is pivotal in mitigating infectious disease transmission and enhancing public health outcomes. This study focuses on detailing the national surveillance system for alcohol-based hand rub (ABHR) consumption in healthcare facilities across Italy, presenting results from a comprehensive three-year evaluation period, from 2020 to 2022. It aims to delineate this surveillance system and report on ABHR consumption trends in various Regions/Autonomous Provinces (Rs/APs).

Impact of COVID-19 on healthcare-associated infections and antimicrobial use in Italy, 2022.

Background: It is unknown whether COVID-19 patients are at higher risk due to demographic and clinical characteristics associated with higher COVID-19 infection risk and severity of infection, or due to the disease and its management.

Aim: To assess the impact of COVID-19 on healthcare-associated infection (HAI) transmission and antimicrobial use (AMU) prevalence during the later stages of the pandemic.

Methods: A point-prevalence survey (PPS) was conducted among 325 acute care hospitals of 19 out of 21 Regions of Italy, during November 2022.

Level of implementation of multimodal strategies for infection prevention and control interventions and prevalence of healthcare-associated infections in Northern Italy.

Background: In November 2022, Italy participated in the third edition of the European Centre for disease prevention and control (ECDC) point prevalence survey (PPS) of healthcare-associated infections (HAIs) in acute-care hospitals. A questionnaire based on the WHO infection prevention and control assessment framework (IPCAF) was included, which aims to investigate multimodal strategies for the implementation of IPC interventions.

Methods: A PPS was conducted using the ECDC PPS protocol version 6.
