Abstract
Objective
To determine risk factors of infections with piperacillin/tazobactam-resistant Escherichia coli in critical care patients.
Design
Prospective, consecutive sample survey study.
Setting
Surgical intensive care unit (ICU) in a university hospital.
Patients
A consecutive series of 133 patients from whom culture results were positive for E. coli during their ICU stay.
Measurements and main results
Multivariate logistic regression analysis identified the following significant independent factors associated with the emergence of a piperacillin/tazobactam-resistant Escherichia coli: prior use of amoxicillin (odds ratio, 4.15) and amoxicillin/clavulanate (odds ratio, 3.25).
Conclusions
Treatment with amoxicillin or amoxicillin/clavulanate is a major risk factor for the detection of piperacillin/tazobactam-resistant E. coli in ICU patients.
