{Abstract}: BACKGROUND: Data on multiple consecutive health care-associated infections (HAIs) in patients undergoing extracorporeal membrane oxygenation (ECMO) are limited. We aim to identify the characteristics and outcomes of multiple, consecutive HAIs.
METHODS: This retrospective study included adult patients who underwent ECMO in a single cardiac ICU in China from May 2015 to December 2022. The incidence, clinical characteristics, risk factors, and impact on in-hospital mortality among patients with non-HAI, single HAI, and multiple HAIs were analyzed. Pathogens and infection sites for each new episode were compared.
RESULTS: Of 192 patients, 92 (47.92%) developed 141 separate infections, with 41 (21.35%) experiencing multiple infections during a single ECMO period. Respiratory tract infections (RTIs) constituted the majority (75.89%), and gram-negative bacteria were the predominant pathogens (71.63%). RTIs decreased from 86.9% in the first infection to 14.3% in the third (P < .001), while bloodstream infections increased from 10.9 % to 57.1% (P < .001). The proportion of gram-positive bacteria increased from 9.8% to 42.9% (P = .032). Prolonged ECMO duration was the only independent risk factor for multiple consecutive HAIs (odds ratio (OR)=1.220, P < .001).
CONCLUSIONS: Multiple consecutive HAIs during ECMO were frequent, with distinct microbiological changes between initial and subsequent HAIs.
