Burden of Healthcare-Associated Infections on Mortality Among COVID-19 Hospitalized Patients

Year: 2025

Type: article

Abstract: BACKGROUND: Healthcare-associated infections (HAIs) are a significant public health problem, having a decisive impact on the prognosis of patients hospitalized with COVID-19. In Romania, the absence of a uniform reporting system and the lack of epidemiological data comparable to European standards limit the real assessment of their incidence and consequences. METHODS: In this context, the present study aimed to conduct an integrated analysis of the clinical, epidemiological, and microbiological factors involved in the mortality of patients with COVID-19 and HAIs in a county located in southeastern Romania. This research was based on a retrospective observational study that included 295 patients with a confirmed diagnosis of COVID-19 and at least one documented HAI between January 2020 and December 2022. Data were extracted from standardized reporting forms, and statistical analyses included tests (Fisher's exact test, Mann-Whitney U), ROC curves, Kaplan-Meier survival analysis, and Cox proportional hazard regression. RESULTS: was the predominant pathogen (84.1%), and the threshold of ≥63.5 years demonstrated predictive value for mortality. In multivariate models, age greater than 63 years and gastrointestinal surgery were confirmed as independent predictors of death. CONCLUSIONS: The findings highlight the substantial impact of HAIs on the clinical progression of COVID-19 patients, underscoring the need for comprehensive systemic interventions, including enhanced prevention and control strategies, prudent antimicrobial therapy, and standardized epidemiological monitoring. Implementing these measures is crucial to mitigating HAIs' effects and improving patient outcomes in similar situations.
