BACKGROUND: Hospital-acquired urinary tract infections (UTIs) significantly impact hospital outcomes. Colorectal surgery is inherently high risk for postoperative infections including UTI, and these patients may have unique outcomes as compared to other medical and surgical hospitalizations. We aim to assess the impact of the differing definitions of UTI captured by our hospital quality measures on hospital charges, length of stay (LOS), and mortality after colorectal resections at our institution.
MATERIALS AND METHODS: Existing hospital quality surveillance was used to retrospectively identify postcolorectal resection UTI, as defined by the National Surgical Quality Improvement Program (NSQIP), and the Centers for Disease Control and Prevention's National Healthcare Safety Network (NHSN)-defined catheter-associated UTIs (CAUTI), from 2006-2012. Both groups were compared to colorectal resections performed during the same period that did not develop a UTI. Groups were compared for differences in 30-d surgical outcomes with multivariate analysis of total hospital charges and LOS.
RESULTS: During our study period, we identified 18 CAUTIs and 42 NSQIP-UTI, and 1064 other colorectal resections (UTI rate, 5.3%). Our overall mortality rate was 4.4% and was not associated with CAUTI or NSQIP-UTI on univariate analysis. CAUTI, but not NSQIP-UTI, was associated with a 73% increase in LOS and 70% increase in total hospital charges on multivariate analysis.
CONCLUSIONS: By reviewing quality outcomes surveillance modalities at our hospital, we identified postcolorectal resection CAUTI, but not NSQIP-UTI, to be associated with increased total hospital charges and LOS. Neither was associated with mortality.
