1131. You’re Never Too Old for a Time-Out: Implementing Antibiotic Time-Outs on Pediatric Inpatient Teams

Abstract Background Antibiotic overuse leads to antimicrobial resistance, adverse events, and excess costs. Antibiotic time-outs (ABTOs) offer a structured approach to reevaluate antimicrobial regimens, but implementing and maintaining ABTOs can be challenging. In this project, we built on previous ABTO implementation in adult inpatient units to incorporate ABTOs in pediatrics using quality improvement (QI) methods. Methods We identified champions, including attending physicians, residents, nurses, team coordinators, and pharmacists. Following pilot testing, ABTOs began in November 2019 and January 2020 for two general pediatric teams, and in June 2020 in the pediatric ICU (PICU). Patients were eligible for an ABTO if they had been on antibiotics for 36-72 hours. ABTOs were documented in the electronic medical record (EMR) with a structured note template. These notes along with patient antimicrobial regimens were extracted and analyzed using an automated EMR query. Metrics included: (1) Proportion of ABTO-eligible patients with an ABTO; (2) Proportion of ABTOs conducted within goal time frame; (3) Documented plan changes in ABTO (e.g. change IV antibiotics to PO); and (4) Proportion of documented changes completed within 24 hours Results To date, there have been 342 pediatric ABTOs over 145 team weeks on the general pediatrics teams and 50 weeks in the PICU, representing 96.9% of eligible patients. 77.8% of ABTOs were completed within the recommended time frame. A majority of ABTOs (67%) resulted in no change to antibiotic regimen, and 18% of patients had already had de-escalation. In 10.5% of patients, the ABTO led to a de-escalation (antibiotics discontinued in 2%, converted from IV to PO in 8.5%). 86.8% of planned changes occurred within 24 hours of ABTO. Figure 1.

Conclusion This project demonstrates that ABTOs can be implemented across a variety of teams and showed successful spread of an adult-based QI project to pediatrics. ABTOs led to clear de-escalation in 10.5% of cases, with other changes made in 5% of cases. Future directions include continued spread to inpatient teams, development of EMR-based ABTO alerts, comparison of overall antibiotic use and adverse events before and after ABTO implementation, and characterization of antimicrobial optimization prior to ABTO.
