Implementation of Electronic Clinical Decision Support Tools for Antibiotic Stewardship in Pediatric Appendicitis

Abstract

Background The efficacy of clinical decision support (CDS) tools to promote antibiotic stewardship in pediatric appendicitis remains poorly understood. Here, we developed an electronic order panel (OP) to assist with decreased utilization of extended spectrum antibiotics. Methods Retrospective review of patients (≤18 years) at a single institution from May 2018 to October 2019 treated with ≥1 dose of preferred (narrow) or nonpreferred (broad-spectrum) antibiotics was performed, and they were categorized as pre- (PIC) or postimplementation cohorts (PISC). Results Of 234 encounters, 170 (73%) and 107 (46%) received preferred and nonpreferred antibiotics, respectively. Postimplementation cohort encounters had a sustained 50% increase in preferred antibiotic use compared to PIC (92% vs 42%, P = .014). Order panel utilization accounted for 31% of overall encounters and 44% of PISC encounters. Conclusion Despite sustained improvement in antibiotic stewardship, OP utilization remains low. The use of CDS tools may not be a good process measure for quality improvement.
