Postoperative urinary tract infections (UTIs)
Centers for Medicare & Medicaid Services (CMS), Medicare Patient Safety Monitoring System (MPSMS).
2.31 Percent of surgical discharges with postoperative urinary tract infections, United States, 2002 and 2003.
- CMS, MPSMS, inpatient medical records: for abstracted data related to the index hospital stay.
- CMS Medicare Administrative Data: used to identify a major surgical procedure and for 30-day post-procedure mortality.
All discharges from the MPSMS sample with documentation of 1 or more procedure identified in conjunction with the Surgical Care Improvement Project without an indwelling catheter on arrival or evidence of a urinary tract infection before the procedure.
Subset of the denominator with a diagnosed postoperative urinary tract infection during the index hospital stay.
Diagnosed postoperative UTIs are defined as cases with 1 of the following:
- A postoperative urine culture containing more than 105 organisms/cc with no more than 2 of the following pathogens: Escherichia coli, Enterococcus species, Klebsiella species, Pseudomonas species, Proteus species, Enterobacter species, Citrobacter species, fungi including Candida species and Staphylococcus aureus.
- A physician diagnosis of UTI and an antibiotic ordered by a physician to treat the UTI.
In order to attain greater consistency between 2002 and 2003 data, the analytic approach used to produce these tables differs from earlier years of the NHQR.
