Abstract
Urine cultures have been ordered inappropriately among many asymptomatic hospitalized patients. This study aimed to assess how a new urine culture order note incorporated into an electronic health record system impacted the number and appropriateness of urine cultures performed.
A quasi-experimental before-and-after intervention.
The study was conducted at the Veterans Affairs Connecticut Healthcare System (VACTHS) in West Haven, Connecticut.
The study included hospitalized adult patients who had urine cultures performed from January 1st, 2023, to October 31st, 2024.
The intervention was the addition of a mandatory urine culture order note that linked to a urine culture order in the electronic health record. The note required providers to choose an indication for ordering a urine culture. The study outcomes were the percentage of appropriateness associated with urine cultures and the number of urine cultures per 100 admissions performed pre- and post-intervention.
Following the initiation of the mandatory urine culture order note, the percentage of appropriateness increased from 20.6% before the intervention to 59.6% after the intervention (P < .01). The average monthly number of urine cultures per 100 admissions performed decreased from 18.6 before the intervention to 10 after the intervention, a significant 46.3% reduction.
The implementation of a mandatory urine culture order note linked to the urine culture order resulted in increased urine culture order appropriateness and a significant decrease in number of orders for urine cultures.
