Surveillance for postoperative wound infections: practical aspects.

M Kerstein, M Flower, L M Harkavy

    The American Surgeon
    |April 1, 1978

    Summary

    Intensive surveillance identified high postoperative wound infection rates, particularly for clean-contaminated wounds during one survey period. Close collaboration between infection control and surgical teams is crucial for effective wound surveillance.

    Area of Science:

    • Healthcare epidemiology
    • Surgical site infection surveillance
    • Infection control practices

    Background:

    • Postoperative wound infections pose a significant risk to patient outcomes.
    • Effective surveillance is essential for identifying and mitigating infection risks.
    • Previous surveillance efforts may not capture dynamic changes in infection rates.

    Purpose of the Study:

    • To assess postoperative wound infection rates through intensive surveillance.
    • To identify specific wound classifications and surgical services with higher infection burdens.
    • To evaluate the effectiveness of current wound surveillance methods.

    Main Methods:

    • Intensive surveillance for postoperative wound infections conducted over three separate one-month periods.

  • Categorization of wounds into clean, clean-contaminated, contaminated, and dirty classifications.
  • Statistical analysis to compare infection rates across different periods and wound types.

    • Main Results:

    • Mean infection rates were 6% (clean), 11% (clean-contaminated), 17% (contaminated), and 18% (dirty).
    • A significantly higher clean-contaminated wound infection rate (25%) was observed during the second survey period (p < 0.05).
    • A majority of infections were concentrated within a single surgical subspecialty service.

    Conclusions:

    • Intensive surveillance effectively highlights variations in postoperative wound infection rates.
    • The findings underscore the need for a strong liaison between infection control teams and surgical services.
    • Addressing identified high-risk areas and improving surveillance methods are critical for reducing surgical site infections.
