CO22 | Differences in health associated infections in two different hospital settings: a Medicine ward and Long-Term Medicine ward

Premises and Purpose of the study: Healthcare-associated infections (HAIs) represent one of the most frequent adverse events in healthcare, both due to the endemic spread of some microorganisms and the occurrence of epidemics, and constitute a relevant public health problem. HAIs have a significant impact on morbidity, mortality and quality of life and represent an economic burden.Materials and Methods: We evaluated the prevalence of germs in two different hospitals in Campania: the Medicine of the AO dei Colli and the Long-Term Care Medicine of the AORN Cardarelli of Naples in the year 2022. No. 788 blood cultures (EMC) in the AO dei Colli and 852 in the AORN Cardarelli were performed.Results: On the 788 EMC of the AO dei Colli we observed 20% CRE (13% E. coli, 6.9% Klebsiella), 10% CRAB (Acinetobacter), 18% CRPsA (Pseudomonas ae). vs. 852 AORN Cardarelli with 5% CRE (1.5% E. coli, 3.5% Klebsiella), 4% CRAB (Acinetobacter) and 11.2% CRPsa (Pseudomonas ae). In this AORN the most prevalent germ is Staph. Coag neg (20%) followed by Staph. Haemoliticus 15% as well as Candida tropicalis 20%, Candida albicans 15%.Conclusions: These differences in the two Medicine wards are probably due to the different typology of hospitalized patients: in the AO dei Colli Medicine ward patients arrive directly from the Emergency Department, in the Cardarelli ward having they already been admitted to other Medicine wards and subsequently to the Long-Term Care Unit. We are still evaluating the results for the year 2023.
