[h=3]Abstract[/h] [h=4]BACKGROUND:[/h] Healthcare-associated infections (HAIs) increase morbidity and mortality. During 2014, at the Hospital Clinico Red de Salud UC Christus (RS-UCCH) it was estimated that 15% of respiratory viral infections were acquired during hospitalization and influenza A was more frequent.
[h=4]AIMS:[/h] Clinical and epidemiological characterization of HAIs due to influenza virus in patients hospitalized in critical care units (CCU) and special care.
[h=4]METHODS:[/h] Descriptive study. We included patients hospitalized in CCU and special care with hospital acquired influenza during 2014-2017. HAI due to influenza was defined as: symptom onset and/or positive influenza PCR after ≥ 48 hours of hospital admission, without previous respiratory symptoms or previous negative influenza test study.
[h=4]RESULTS:[/h] 22 patients were identified, median age was 74 years. Influenza was acquired average on day 13. Influenza A was detected in 77% and 27% had respiratory co-infection. Thirteen (59%) were hospitalized in CCU, only 2 (15%) due to lung problems. Comorbidity was present in 86% and decompensation in 50%. Only 41% received influenza vaccine. The associated lethality was 18%.
[h=4]CONCLUSIONS:[/h] HAI due to influenza occurred in chronic, older and unvaccinated patients. Education about HAIs and continuous high vaccination coverage must be reinforced.
