    This study found that antimicrobial use in a hospital setting, particularly for surgical prophylaxis, often deviates from appropriate guidelines. Improving antimicrobial stewardship is crucial for effective patient care and combating resistance.

    Area of Science:

    • Infectious Diseases
    • Hospital Epidemiology
    • Antimicrobial Stewardship

    Background:

    • Antimicrobial surveillance programs are essential for monitoring drug usage patterns in healthcare settings.
    • Optimizing antimicrobial use is critical for patient outcomes and preventing antimicrobial resistance.
    • Veterans Affairs hospitals implement surveillance to ensure appropriate antimicrobial prescribing.

    Purpose of the Study:

    • To assess the appropriateness of inpatient antimicrobial usage in a Veterans Affairs hospital.
    • To identify areas of suboptimal antimicrobial prescribing, particularly for surgical prophylaxis and common infections.
    • To inform antimicrobial stewardship initiatives through data-driven insights.

    Main Methods:

    • A nurse-epidemiologist collected and reviewed antimicrobial usage data.

  • Data were analyzed weekly in conjunction with an infectious disease physician.
  • Appropriateness was evaluated against established criteria for therapeutic and prophylactic indications.

    • Main Results:

    • Only 31% of antimicrobial usages for surgical prophylaxis met appropriate criteria.
    • Approximately 65% of antimicrobial uses for wound and urinary tract infections were deemed appropriate.
    • Over 85% of antimicrobial treatments for respiratory tract infections and sepsis were appropriate on the medical service.

    Conclusions:

    • Significant opportunities exist to improve antimicrobial prescribing practices, especially for surgical prophylaxis.
    • Antimicrobial stewardship interventions are needed to enhance appropriate drug selection and duration.
    • Continued surveillance is vital for effective antimicrobial management in hospital settings.
