Abstract

Background: Approximately 30% of antimicrobials prescribed in the outpatient setting are unnecessary and up to 50% are inappropriate. Despite this, antimicrobial stewardship (AS) efforts mostly focus on the inpatient setting, and limited data describe AS interventions at hospital discharge. Acknowledging the potential value of discharge AS, we used our existing resources to review discharge oral antimicrobial prescriptions. Objective: The primary objective of this retrospective, single-center study was to evaluate the impact of an AS program on discharge oral antimicrobial prescriptions. Methods Discharge oral antimicrobial prescriptions sent to our hospital-operated outpatient pharmacy, reviewed by an infectious diseases (ID) pharmacist, and recorded into our data collection tool from September 1, 2020, to February 28, 2021, were evaluated retrospectively. The primary outcome was to identify the frequency a drug-related problem (DRP) was identified by an ID pharmacist. Secondary outcomes included DRP characterization, percentage of prescriptions with interventions, intervention acceptance rate, and reduction in antimicrobial days dispensed at discharge when interventions to limit treatment duration were accepted. Results: Of the 803 discharge oral antimicrobial prescriptions reviewed, at least 1 DRP was identified in 43.1% (346/803). The most frequently identified DRPs pertained to treatment duration, drug selection, and dose selection. At least 1 intervention was recommended in 42.8% (344/803) of prescriptions. In total, 438 interventions were made and the acceptance rate was 75.6% (331/438). The most common types of interventions included recommendations for a different duration, a different dose or frequency, and antimicrobial discontinuation. When interventions to reduce treatment duration were accepted, the median (interquartile range) number of antimicrobial days decreased from 8 (5-10) days to 4 (0-5.5) days ( P < 0.001). Conclusion and Relevance: An ID pharmacist’s review of discharge oral antimicrobial prescriptions sent to our hospital-operated outpatient pharmacy resulted in identification of DRPs and subsequent interventions in a substantial number of prescriptions.
