How does an Antimicrobial Stewardship Program (ASP) evaluate the appropriateness of antibiotic therapy?

An Antimicrobial Stewardship Program (ASP) evaluates the appropriateness of antibiotic therapy primarily by reviewing patient cases to ensure adherence to evidence-based guidelines and appropriate prescribing practices. This process involves a comprehensive analysis of clinical data, patient histories, and current treatment plans to assess whether prescribed antibiotics are necessary, appropriate, and aligned with established treatment protocols.

The focus on evidence-based guidelines is crucial because it ensures that the selection and use of antibiotics are based on the best available research and clinical practices. This not only supports optimal patient outcomes but also helps mitigate the risks associated with antibiotic misuse, such as the development of antibiotic resistance. By focusing on the evaluation of individual patient cases, the ASP can identify areas for improvement in prescribing habits and promote judicious use of antimicrobials.

Other approaches, such as conducting market research on antibiotic sales or analyzing lab results for antibiotic resistance, while valuable in their own contexts, do not directly evaluate the appropriateness of therapy in a patient-centered manner. Monitoring medication adherence through surveys also does not directly assess the clinical appropriateness of the antibiotic choice itself, but rather how well patients follow their prescribed regimens. Therefore, reviewing patient cases through the lens of evidence-based guidelines is the most effective way for an ASP to evaluate and ensure
