Environmental exposure to carbapenem-resistant Acinetobacter baumannii as a risk factor for patient acquisition of A. baumannii

Infect Control Hosp Epidemiol. 2014 Apr;35(4):430-3. doi: 10.1086/675601.

Abstract

We aimed to determine the association between environmental exposure to carbapenem-resistant Acinetobacter baumannii and the subsequent risk of acquiring this organism. Patients exposed to a contaminated hospital environment had 2.77 times the risk of acquiring carbapenem-resistant A. baumannii than did unexposed patients (relative risk, 2.77 [95% confidence interval, 1.50-5.13]; P = .002).
