Abstract

Objective:

To evaluate oral antibiotic prescribing for common infections at hospital discharge before and after implementation of a pharmacist-driven transitions-of-care (TOC) program.

Design:

Single-center before-and-after study.

Setting:

Acute-care, academic, community hospital in Santa Barbara, California.

Patients:

Eligible adult patients prescribed oral antibiotics at hospital discharge for community-acquired pneumonia, skin and soft-tissue infections, and urinary tract infections between September 2019 and December 2019 (preimplementation period) and between March 2021 and May 2021 (postimplementation period).

Intervention:

Antimicrobial stewardship–initiated, department-wide, TOC program requiring all clinical pharmacists to review discharge antibiotic prescriptions in real time.

Results:

In total, 260 antibiotic prescriptions were assessed for appropriateness: 140 before implementation and 120 after implementation. After implementation, the number of prescriptions considered inappropriate significantly decreased by 18% (52% vs 34%; P = .005). Inappropriate rates decreased in all assessment categories: dosing (15% vs 2%; P < .001), treatment duration (42% vs 31%; P = .08), antibiotic selection based on infection type or microbiology (8% vs 4%; P = .33), and antibiotics not indicated (16% vs 10%; P = .18). Median total antibiotic days decreased by 1 day after implementation (10 days vs 9 days; P = .67), and 30-day readmission rates were similar between both phases.

Conclusions:

A real-time, pharmacist-driven, TOC program for oral antibiotic prescriptions had a significant impact in reducing inappropriate prescribing of antibiotics at hospital discharge for common infections. Incorporating discharge antibiotic prescription review into pharmacist daily workflow may be a sustainable approach to outpatient antimicrobial stewardship in a setting with limited resources.
