Abstract

We prospectively studied the value of systematic rectal swabs performed for the detection of colonization and the prediction of infections by Acinetobacter baumanii in 751 consecutive patients admitted to five intensive-care units (ICUs) over an 8-month period. Gastrointestinal tract colonization was found in 8.7% of ICU admissions. The positive and negative predictive values of rectal swabs for the detection of subsequent infection were 17% and 99%, respectively. Sensitivity and specificity were 55% and 93%, respectively. We also determined the comparative values of rectal or nasal swabs and skin cultures for the detection of A baumanii colonization in 25 patients already colonized or infected with A baumanii. The combination of rectal and nasal swabs was positive in 20 (80%) of 25. The results of the present study suggest that detection of gastrointestinal tract A baumanii colonization is not an accurate predictor of subsequent A baumanii infection and that combined rectal and nasal swabs might be used for the detection of A baumanii colonization in ICU patients.
