Abstract
Introduction
Among antimicrobial stewardship team (AST) activities, de-escalation, which is aimed at optimizing antibiotic use, lacks a standardized evaluation method. The Duke Antimicrobial Stewardship Outreach Network (DASON) criteria provide a framework for assessing de-escalation; however, their applicability in small to medium-sized hospitals in Japan has remained unclear. We aimed to evaluate the effectiveness of AST pharmacist-led post-prescription review and feedback (PPRF) using multiple indicators, including de-escalation based on the DASON criteria, to determine whether these indicators are also applicable in medium-sized hospitals.
Methods
A retrospective study was conducted at a 330-bed hospital, comparing pre-PPRF (April 2021 to March 2022) and post-PPRF (April 2022 to March 2023) periods. The effectiveness of AST pharmacist-led PPRF was evaluated using the de-escalation rate determined by the DASON criteria, inappropriate antibiotic use in definitive therapy, days of therapy (DOT), and days of antibiotic spectrum coverage (DASC) per DOT.
Results
The de-escalation rate significantly increased from 20 % to 45 % (P < 0.01), and inappropriate antibiotic use in definitive therapy decreased from 7 % to 0 % after AST pharmacist-led PPRF. While DOT significantly increased from 11 days to 13 days (P = 0.02), no significant change was observed in the DASC/DOT ratio.
Conclusion
This study suggests that de-escalation based on the DASON criteria can be an effective quantitative indicator for evaluating AST pharmacist-led PPRF in medium-sized hospitals. The findings also suggest that incorporating multiple indicators tailored to each hospital's conditions can provide a more comprehensive framework for evaluating AST pharmacist-led PPRF.
期刊介绍:
The Journal of Infection and Chemotherapy (JIC) — official journal of the Japanese Society of Chemotherapy and The Japanese Association for Infectious Diseases — welcomes original papers, laboratory or clinical, as well as case reports, notes, committee reports, surveillance and guidelines from all parts of the world on all aspects of chemotherapy, covering the pathogenesis, diagnosis, treatment, and control of infection, including treatment with anticancer drugs. Experimental studies on animal models and pharmacokinetics, and reports on epidemiology and clinical trials are particularly welcome.
