Utility of UB-92 data for monitoring emergency department performance improvement

The Universal Billing Code of 1992 (UB-92) is a standard database used by hospitals to generate itemized charges for patient visits. This study examined the use of UB-92 information to monitor emergency department performance improvement projects. UB-92 data were used to determine whether urine tests had been ordered for emergency department patients. A population of patients at low risk for requiring a urine culture was defined as discharged female patients between 16 and 60 years of age undergoing a urinalysis as part of their emergency department treatment during a 10-month period. Based on UB-92 data, only a total of 2,138 patients were identified who met the study's low-risk criteria. Recommendations for the optimum use of these tests were presented to the emergency physicians as part of departmental performance improvement activities. Additional logistical problems associated with the procedure for ordering this test were identified and corrected as part of this project. After an additional 5-month period, a second analysis of the entire 15 months of UB-92 data was performed. Prior to physician notification, 41.6% of low-risk patients underwent both a urinalysis and a urine culture and sensitivity in the emergency department. In the 5-month follow-up period, the percentage of patients undergoing both tests decreased 18% to only 23%.
