Point prevalence survey on healthcare-associated infections in Apulian region, Italy, 2022-2023

BACKGROUND: Since 2011-2012, the ECDC coordinates the measurement of Healthcare-associated infections (HAIs) and antimicrobial use (AMU) in European acute-care hospitals through repeated point prevalence surveys (PPS) every five years. Here we present the main results of the 3rd ECDC-PPS conducted in Apulia region, Italy, during November 2022, in comparison as a benchmark with data from Italian PPS 2016-2017. METHODS: The ECDC protocols were applied. Prevalence of HAIs and AMU was expressed as percentages. Proportion of isolates resistant to selected AMR markers were also calculated. RESULTS: Twenty-four/39 Apulian hospitals provided data on 3,710 patients. The prevalence of patients with ≥1 HAI was 9.9% (PPS-2016-17:8.03%). The highest prevalence was recorded in rehabilitation wards (31.6%; PPS-2016-17:16.4%), in large hospitals (10.5%; PPS-2016-17:9.3%), among elderly (11.2%; PPS-2016-17:9.1%), males (11.1%; PPS-2016-17:7.9%), and patients with a rapidly fatal McCabe score (28%; PPS-2016-17:18.8%). The most reported types of HAI were pneumonia (19.8%; PPS-2016-17:22.8%) and urinary tract infections (18.3%; PPS-2016-17:18%). Prevalence of patients with ≥1 antimicrobial was 49.3% (PPS-2016-17:44.5%). At least a positive microbiological result was reported for 66.1% of the HAIs (N = 244/369; PPS-2016-17:53.8%). Klebsiella pneumoniae (14.9%; PPS-2016-17:10.4%) and Escherichia coli (9.8%; PPS-2016-17: 13%) were the most frequently isolated microorganisms. The susceptibility tests were available for 56% of microorganisms (N = 177/316) and a resistant result was reported for 50.3% (PPS-2016-17:42.3%) of tests. CONCLUSIONS: HAI, AMU, and AMR prevalence estimated in Apulia region was higher, when compared with previous national PPS. Efforts in implementing antimicrobial stewardship and reducing HAIs should be established. KEY MESSAGES: • HAI and AMR remain a major public health threat in Apulia region, particularly for K. pneumoniae and E. coli. • Frail patients bear a greater burden of illness.
