New Study Reveals Key Strategies to Reduce Post-Discharge Antibiotic Use
A recent study published in Infection Control & Hospital Epidemiology has uncovered effective strategies to minimize post-discharge antibiotic use in Veterans Affairs (VA) hospitals. Researchers analyzed data from 123 VA hospitals, focusing on the impact of antimicrobial stewardship practices and antibiotic prescribing guidelines.”
Collaboration and Guidelines Show Significant Results
The study found that frequent interactions between stewardship champions—such as physicians and pharmacists—and a commitment to local antibiotic prescribing guidelines were critical factors in reducing unnecessary antibiotic use following hospital discharge.
Researchers evaluated 396,909 patient admissions from May 2020 to May 2021, categorizing the hospitals into high-performing, low-performing, and intermediate-performing groups based on their antibiotic prescribing metrics.
High-Performing Hospitals Identified
Out of the 123 hospitals, 37 (30.1%) were classified as high-performing, with reduced antibiotic use and shorter treatment durations at discharge. In contrast, 22 hospitals (17.9%) were marked as low-performing due to higher antibiotic prescribed rates and longer treatment courses. The remaining 64 hospitals (52%) fell into the intermediate-performing category.
Stewardship Processes Key to Dispensing Success
Among the high-performing hospitals, 70.3% reported frequent interactions between stewardship champions, compared to only 22.7% at the low-performing sites. Moreover, 97.3% of high-performing hospitals had educated their inpatient providers on stewardship principles within the past year, versus 77.3% at low-performing facilities.
Core Elements for Stewardship Programs Highlighted
The analysis used a multinomial logistic regression model, revealing that low-performing hospitals were significantly less likely to have daily or weekly communications between stewardship physicians and pharmacists (odds ratio [OR], 0.12; 95% confidence interval [CI], 0.03 to 0.55). Similarly, they were less likely to use local antibiotic guidelines (OR, 0.21; 95% CI, 0.05 to 0.93). Both practices are recommended by the Centers for Disease Control and Prevention’s Core Elements for Hospital-Based Stewardship Programs.
Practical Impact of Stewardship Strategies
The study authors discussed the importance of these collaborative practices. “Physician engagement contributes significantly to the credibility of initiatives aimed at reducing antibiotic misuse at discharge,” they stated. “Moreover, having easy-to-access local guidelines helps healthcare providers decide on the appropriate duration of antibiotic therapy.”
These findings emphasize the critical role that these stewardship processes play in mitigating antibiotic resistance and promoting a healthier use of antibiotics post-discharge.
Conclusion and Future Implications
The research highlights the necessity of robust antimicrobial stewardship programs and adherence to evidence-based guidelines in reducing post-discharge antibiotic misuse. This could lead to more effective patient care and potentially lower rates of antibiotic-resistant infections.
As hospitals continue to adapt their stewardship practices, these findings serve as a valuable guide for optimizing antibiotic use and improving patient outcomes.
