Antimicrobial Stewardship in Inpatient Settings in the Asia Pacific Region: A Systematic Review and Meta-analysis.

Abstract

Background An antimicrobial stewardship program (ASP) is one of the core elements needed to optimize antimicrobial use. Although collaboration at the national level to address the importance of ASPs and antimicrobial resistance has occurred in the Asia Pacific region, hospital-level ASP implementation in this region has not been comprehensively evaluated. Methods We conducted a systematic review and meta-analysis to assess the efficacy of ASPs in inpatient settings in the Asia Pacific region from January 2005 through March 2016. The impact of ASPs on various outcomes, including patient clinical outcomes, antimicrobial prescription outcomes, microbiological outcomes, and expenditure were assessed. Results Forty-six studies were included for a systematic review and meta-analysis. The pooled risk ratio for mortality from ASP before-after trials and 2-group comparative studies were 1.03 (95% confidence interval [CI], .88-1.19) and 0.69 (95% CI, .56-.86), respectively. The pooled effect size for change in overall antimicrobial and carbapenem consumption (% difference) was -9.74% (95% CI, -18.93% to -.99%) and -10.56% (95% CI, -19.99% to -3.03%), respectively. Trends toward decreases in the incidence of multidrug-resistant organisms and antimicrobial expenditure (range, 9.7%-58.1% reduction in cost in the intervention period/arm) were also observed. Conclusions ASPs in inpatient settings in the Asia Pacific region appear to be safe and effective to reduce antimicrobial consumption and improve outcomes. However, given the significant variations in assessing the efficacy of ASPs, high-quality studies using standardized surveillance methodology for antimicrobial consumption and similar metrics for outcome measurement are needed to further promote antimicrobial stewardship in this region.
