Healthcare organizations can measure the effectiveness of antimicrobial stewardship programs (ASPs) through several key metrics:
Antimicrobial Utilization Metrics: Track Defined Daily Dose (DDD) and Days of Therapy (DOT) per 1000 patient-days to monitor antibiotic use.
Clinical Outcomes: Monitor infection rates, such as hospital-acquired infections (HAIs) and multi-drug resistant (MDR) infections, and evaluate treatment success rates and infection-related readmissions.
Microbiological Outcomes: Assess changes in antimicrobial resistance patterns and conduct regular antibiotic susceptibility testing.
Process Measures: Ensure compliance with antimicrobial prescribing guidelines, frequency of reviews, and feedback interventions.
Economic Outcomes: Measure cost savings from reduced antimicrobial use and the impact on hospital length of stay (LOS).
Education and Awareness: Evaluate staff training effectiveness and knowledge on antimicrobial stewardship principles.
Patient Safety and Quality of Care: Monitor adverse drug events (ADEs) and overall patient outcomes, including mortality rates.
Program Structure and Resources: Assess the adequacy of dedicated ASP personnel and the availability of decision-support tools.
