Abstract

OBJECTIVES:

Pediatric Antimicrobial Stewardship Programs (ASP) have been associated with improvements in antibiotic utilization and patient outcomes; however, ASP studies originating from non-freestanding children's hospitals are lacking. In this study, we present the implementation and impact of a multidisciplinary ASP that employs a collaborative physician and pharmacist driven thrice-weekly prospective audit-with-feedback approach at a non-freestanding children's hospital.

METHODS:

Implementation was assessed via descriptive design. Pediatric inpatients maintained on predefined targeted antibiotics of interest for 48 to 72 hours preceding ASP review were eligible for inclusion. Outcomes evaluated included ASP recommendation and provider acceptance rates (overall and by antibiotic and provider specialty). Impact was examined using an interrupted time series design (with a preimplementation period of August 1, 2013, to July 31, 2014 and postimplementation period of December 1, 2014 to May 31, 2016). Eligibility included all targeted antibiotic usage among pediatric inpatients, with a control group comprising those who received antibiotics requiring preauthorization. Outcomes analyzed included days of antibiotic therapy per 1000 patient days (DOT/1000 PD) and 30-day hospital readmission rates over time.

RESULTS:

Postimplementation, 882 antibiotic reviews were performed on 637 patients, with 327 recommendations generated. Reviews of patients maintained on vancomycin and clindamycin, and of those under care of intensivist and hospitalist physicians, were most likely to prompt recommendations. A mean targeted antibiotic usage decrease of 24.8 DOT/1000 PD (95% confidence interval, -62 to 14) was observed postimplementation, with no change in 30-day readmissions (0.64% during both periods).

CONCLUSIONS:

ASP implementation at a non-freestanding children's hospital was feasible and allowed for identification of areas for targeted quality improvement, while demonstrating modest antibiotic use reduction without adversely impacting patient care.
