    An educational program improved antibiotic prophylaxis timing and duration for surgical patients. This initiative enhanced adherence to guidelines for appropriate antibiotic use in hospitals, demonstrating effective physician prescribing modification.

    Area of Science:

    • Medical Education
    • Infectious Disease Prevention
    • Surgical Patient Care

    Background:

    • Antibiotic prophylaxis is crucial in surgery to prevent infections.
    • Inappropriate use of surgical prophylaxis can lead to resistance and increased costs.
    • Educational interventions are a common strategy to improve clinical practice.

    Purpose of the Study:

    • To assess the impact of a multihospital educational program on the appropriateness of antibiotic prophylaxis in surgical patients.
    • To evaluate changes in the timing and duration of antibiotic use post-intervention.
    • To determine if educational campaigns can modify physician prescribing habits.

    Main Methods:

    • A pre- and post-intervention study design was employed.
    • Data were collected from a large cohort of surgical patients across multiple institutions.

  • Key metrics included the proportion of patients receiving prophylaxis within four hours of incision and the duration of prophylaxis.

    • Main Results:

    • No significant change was observed in the overall proportion of patients receiving prophylaxis for clean procedures.
    • A significant improvement was noted in the proportion of patients receiving prophylaxis within the recommended four-hour window (41% vs. 65%, P < .001).
    • The mean duration of antibiotic prophylaxis decreased significantly (2.5 days vs. 3.4 days, P < .01), and adherence to both timing and duration criteria improved (31% vs. 53%, P < .001).

    Conclusions:

    • Multihospital educational programs can effectively modify physicians' antibiotic prescribing practices.
    • Targeted educational interventions can improve the appropriateness of surgical antibiotic prophylaxis.
    • Relatively low-cost educational initiatives show promise in optimizing antibiotic use in surgical settings.
