Abstract
Repeated point prevalence surveys (PPSs) of healthcare-associated infections (HAIs) and antibiotic use are crucial to monitor trends over years at regional level, especially in countries with decentralized healthcare systems. Here, we reported the results of three PPSs conducted in Sicilian acute care hospitals (Italy) from 2016 to 2018, according to the European Centre for Disease Prevention and Control protocol. Overall, prevalence of patients with at least one HAI was 5.1% in 2016, 4.7% in 2017, and 5.1% in 2018, without a significant trend over years (p = 0.434). At the patient level, the most important factor associated with HAIs was antibiotic use, since patients receiving at least one antimicrobial were more likely to be infected than those who did not receive antimicrobials (OR = 18.87; 95%CI = 13.08–27.22). The analysis of the prevalence of antibiotic use indicated a significant trend across years of the PPSs: 50.5% of patients received at least one antimicrobial agent in 2016, 55.2% in 2017, and 53.7% in 2018 (p < 0.001). The most common indication for antimicrobial prescription was medical prophylaxis, while third-generation cephalosporins represented the most frequently used class of antimicrobial agents, followed by fluoroquinolones and combinations of penicillins. Our study confirms that HAIs still remain a major public health issue, which could be intensified by antibiotic abuse. This raises the need for infection prevention and control and antibiotic stewardship programs aimed to improve knowledge about appropriate antibiotic prescription and to reduce the use of broad-spectrum antimicrobials.
Highlights
Healthcare-associated infections (HAIs) are one of the major threats for public health worldwide, due to their significant impact on mortality, hospital stays, and assistance costs [1,2,3,4,5,6]

Summary
Healthcare-associated infections (HAIs) are one of the major threats for public health worldwide, due to their significant impact on mortality, hospital stays, and assistance costs [1,2,3,4,5,6]. Repeating the survey at predefined intervals could be a useful way to avoid some of its limitations [16,17] and to evaluate trends of HAIs and antimicrobial use across years. This is especially important in countries with decentralized healthcare systems, such as Italy, where regional administrations play a crucial role in IPC programs [18,19,20,21,22].
