Wound infections in general surgery. A two-year prospective study in a private hospital

Insights

Surgical wound infection rates varied by wound class, from 1% in clean cases to 19% in dirty cases, with an overall infection rate of 4.2% in this prospective study. Low antibiotic use and strict protocols contributed to minimal mortality from infection.

Area of Science:

  • Surgical infection control
  • Hospital epidemiology
  • Prospective clinical studies

Background:

  • Surgical site infections (SSIs) are a significant concern in healthcare settings.
  • Understanding infection rates across different wound classifications is crucial for prevention strategies.
  • Previous studies highlight the impact of surgical environment and protocols on SSIs.

Purpose of the Study:

  • To prospectively evaluate surgical wound infection rates in a private hospital setting.
  • To analyze infection rates based on wound classification (clean, clean-contaminated, contaminated, dirty).
  • To assess the impact of specific surgical practices on infection and mortality outcomes.

Main Methods:

  • A two-year prospective study involving 1,219 surgical wounds.
  • Data collection on infection rates categorized by wound class.
  • Analysis of mortality and specific surgical interventions, including antibiotic use and sterile technique adherence.

Main Results:

  • Overall surgical wound infection rate was 4.2%.
  • Infection rates by wound class: clean (1%), clean-contaminated (6%), contaminated (15%), and dirty (19%).
  • Mortality rate was 0.8%, with no deaths attributed to infection or septicemia; low antibiotic use (32%) was noted.

Conclusions:

  • Wound classification is a strong predictor of surgical site infection risk.
  • Adherence to sterile techniques, such as systematic glove and instrument changes, may reduce infection rates.
  • Effective infection control can be achieved even with limited antibiotic prophylaxis.
