Antimicrobial stewardship: philosophy versus practice.

Area of Science:

• Infectious Diseases
• Health Policy
• Healthcare Management

Background:

• Growing antimicrobial resistance necessitates judicious antibiotic use.
• Antimicrobial stewardship programs (ASPs) are recommended to preserve antibiotic effectiveness.
• Measuring the impact of ASPs in the United States has proven difficult.

Purpose of the Study:

• To evaluate the challenges in measuring the effectiveness of antimicrobial stewardship programs.
• To propose strategies for enhancing the credibility and impact of ASPs.

Main Methods:

• Literature review on current metrics and challenges in ASP evaluation.
• Analysis of commonly used process and outcome measures.
• Synthesis of recommendations for improving ASP assessment.

Main Results:

• Institutions frequently measure antimicrobial use and costs, rather than patient outcomes, to justify ASP effectiveness.
• Meaningful outcome measurement is hindered by inherent difficulties, lack of resources, and inadequate study designs.
• Current metrics may not fully capture the true impact of ASPs on patient care quality.

Conclusions:

• Enhancing ASP credibility requires refocusing review processes on specific disease states.
• Reassessing the utility of current metrics is crucial for accurate program evaluation.
• Integrating ASP initiatives into broader institutional quality and safety efforts is recommended.
