The researchers compared patterns of inpatient and outpatient antibiotic use among patients who awaited urine culture results and patients whose urine specimens had been submitted for culture and screened using the CLINITEK AUWi System.

The CLINITEK AUWi System has demonstrated effectiveness in flagging urine specimens that have yielded negative results before they can be mistakenly sent for culture, thus reducing the total number of cultures performed and decreasing the length of stay in the hospital.

As a result, we hypothesized that the use of this screening method would impact physician decision making in antibiotic management, resulting in a shorter duration of antibiotic treatment.

This study compared patterns of inpatient and outpatient antibiotic use among patients whose urine specimens submitted for culture were screened using the CLINITEK AUWi System and patients who awaited urine culture results. This article also describes the impact on the antibiotic management of urine culture screening using the CLINITEK AUWi System.

The present quasi-experimental retrospective cohort study included patient records with a urine specimen and hospital admission from 1 month before to 1 month after implementation of the system. We compared data from the pre- and postimplementation groups using the χ 2 test or Fisher exact test.

A similar proportion of patients in the pre- and post-implementation groups were prescribed antibiotics (71.2% vs 80.0%; P = .45); the postimplementation group had a significantly shorter length of stay in hours (median, 226 vs 123; P = .005). The median inpatient antibiotic treatment duration was lower for those in the postimplementation group; however, the duration of outpatient antibiotic treatment was longer.

Our findings suggest that screening specimens using the CLINITEK AUWi System may reduce the excess administration of antibiotics.

In our study results, we found differences in antibiotic management between the inpatient population before and after implementation of the CLINITEK AUWi System for testing of urine specimens before they are sent to be cultured.

Our results revealed a shorter inpatient treatment course and an increased outpatient treatment course in the post-implementation group. A possible explanation of this finding is that suspected UTIs were better managed in the post-implementation group as a result of quicker turnaround times for urine culture screenings.
