An Approach to Improving Compliance of Treatment in Asymptomatic Bacteriuria

Asymptomatic bacteriuria (ASB) is the presence of bacteria in the urine without attributable signs or symptoms of a urinary tract infection (UTI). This condition is often inappropriately treated per the 2019 Infectious Disease Society of America guidelines. This quality improvement project aimed to reduce improper treatment of ASB via a three-phase spaced repetition approach over a 12-month 2021-2022 period within a Michigan emergency department (ED), targeting 43 ED clinicians.

During Phase I, a 20-minute teleconference educational intervention was delivered by an Infectious Disease physician and pharmacist. During Phase II, a "hard stop" was implemented within the electronic health record preventing reflex urinalysis culture without indication. During Phase III, a latent period of no intervention took place. The authors' goal was to achieve > 80% compliance to ASB treatment guidelines.

Overall compliance after the project initiative was 66.7%, an absolute increase of 16.7% from baseline compliance. Using data from 54 patients, this represented a statistically significant (p = 0.01) increase from baseline but fell short of the target of > 80%.

Although the authors fell short of their goal of a 30% increase, data from the project suggests a spaced repetition approach to education and workflow changes could be an effective method to increasing medical provider compliance with treatment of ASB.

Identifying the ideal strategy to change treatment patterns of ED clinicians for ASB to align with guidelines remains key. There is still a need for ongoing efforts in this realm for progress to be made. Keywords: asymptomatic bacteriuria, urinary tract infection, compliance, spaced repetition, antibiotics.
