摘要

Purpose

This systematic review and meta-analysis evaluate the effectiveness of ASPs in managing community-acquired pneumonia (CAP), focusing on antibiotic optimization and resistance mitigation.

Methods

Comprehensive literature searches were conducted in PubMed, Scopus, and Web of Science using PICOS criteria. Studies involving adults with CAP exposed to ASPs were included. Data on clinical, economic, diagnostic, and treatment outcomes were extracted. Random-effects meta-analysis using R software pooled effect sizes. Outcomes reported in at least three studies were analyzed for robustness.

Results

ASPs did not significantly impact in-hospital mortality, length of stay, 30-day readmissions, sample collection rates, or intravenous antibiotic duration. However, notable improvements included shorter time to clinical stability and a 31% reduction in 30-day mortality. Legionella urinary antigen testing frequency increased nearly threefold, and the time from admission to antibiotic initiation was reduced. Enhanced adherence to timely antibiotic administration and recommended regimens was observed, though outcome variability persisted.

Conclusion

ASPs significantly improve CAP management by enhancing clinical stability and accelerating antibiotic initiation. Multifaceted strategies, including rapid diagnostics and clinician education, yield clinical benefits. However, outcome variability suggests a need for tailored interventions. Future research should isolate specific ASP components influencing prescriber behavior. Ongoing investment in education, diagnostics, and interdisciplinary collaboration is vital to optimize CAP treatment and combat antibiotic resistance.
