Catheter-Associated Urinary Tract Infections among Trauma Patients: Poor Quality of Care or Marker of Effective Rescue?

Background: Catheter-associated urinary tract infection (CAUTI) is associated generally with worse outcomes among hospitalized patients, but the impact of CAUTI on clinical outcomes is poorly described in trauma patients. We hypothesized that trauma patients with CAUTI would have worse outcomes such as longer length of stay (LOS), fewer discharges to home, and higher outcome of death. Methods: Patients with LOS >2 d in the 2016 Trauma Quality Improvement Program (TQIP) database were included. Patients with and without CAUTI were matched 1:1 via a propensity score using patient, injury, and hospital factors as covariates. Matched pair analysis was performed to compare difference in clinical outcomes between patients with and without CAUTI. Results: There were 238,274 patients identified, of whom 0.7% had a diagnosis of CAUTI. Prior to matching, CAUTI patients had a higher mortality rate (6.6% vs. 3.4%, p
