Abstract
BACKGROUND: The Core Elements of Outpatient Antibiotic Stewardship provide a framework to improve antibiotic use, but evidence supporting safety are limited. We report the impact of Core Elements implementation within Veterans Health Administration sites.
METHODS: A quasi-experimental controlled study assessed the effects of an intervention targeting antibiotic prescription for uncomplicated acute respiratory tract infections (ARI). Outcomes included per-visit antibiotic prescribing, treatment appropriateness, potential benefits and complications of reduced antibiotic treatment, and change in ARI diagnoses over a 3-year pre-implementation and 1-year post implementation period. Logistic regression adjusted for covariates [OR (95% CI)] and a difference-in-differences analysis compared outcomes between intervention and control sites.
RESULTS: From 2014-2019, there were 16,712 and 51,275 patient-visits in 10 intervention and 40 control sites, respectively. Antibiotic prescribing rates pre-post implementation in intervention sites were 59.7% and 41.5%, respectively; in control sites they were 73.5% and 67.2%, respectively [difference-in-differences p<0.001]. The intervention site pre-post implementation odds ratio to receive appropriate therapy increased [1.67 (1.31, 2.14)] which remained unchanged within control sites [1.04 (0.91, 1.19)]. There was no difference in ARI-related return visits post-implementation [(-1.3% vs. -2.0%; difference-in-differences p=0.76] but all-cause hospitalization was lower within intervention sites [(-0.5% vs. -0.2%); difference-in-differences p=0.02]. The odds ratio to diagnose upper respiratory tract infection not otherwise specified compared to other non-ARI diagnosis increased post-implementation for intervention [1.27(1.21,1.34)] but not control [0.97(0.94,1.01)] sites.
CONCLUSIONS: Implementation of the Core Elements was associated with reduced antibiotic prescribing for uncomplicated ARIs and a reduction in hospitalizations. ARI diagnostic coding changes were observed.
