Does Carbapenem Resistant Enterobacteriaceae Infection Drive Venous Thromboembolism in Patients Admitted to Intensive Care Units Receiving Prophylactic Anticoagulants?
Abstract BackgroundSystemic infections are one of several risk factors leading to the development of inflammation and venous thromboembolism (VTE) formation.Aim of the studyTo assess the risk factors associated with the development of VTE during the stay of critically ill patients in the intensive care unit (ICU).Materials and methodsThis is a matched case-control study of patients with VTE admitted to the ICU, at a single centre, from January 1 2018 to December 31 2019. We included all adult patients who stayed more than two days before the development of VTE. Conditional logistic regression was used to estimate the odds ratio (OR) for the risk factors for VTE.ResultsUnivariate and multivariate analyses uncovered three of six factors to have significant influence in the development of VTE in ICU patients: Carbapenem-resistant Enterobactereaceae (CRE) infections (OR 2.95, 95% confidence interval (CI) 1.21–7.33, p = .010), length of ICU stay (OR 1.02, 95% CI 1.01–1.04, p = .011) and the sequential organ failure assessment (SOFA) score (OR 1.10, 95% CI 1.01–1.20, p = .031); all were found to be independent risk factors in the development of VTE.ConclusionOur findings suggest that in patients admitted to the ICU, CRE infection is a strong trigger to the development of VTE, and draw the attention of the treating clinicians to prioritise these infections in the management protocols to control infection-driven VTE in ICU patients.
