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

Abstract

Abstract 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.
