Surgical wound infection rates remain high despite advances. This study identifies key host and surgical risk factors, highlighting challenges from antibiotic resistance and an aging patient population.

Area of Science:

  • Infectious Diseases
  • Surgical Outcomes
  • Epidemiology

Background:

  • Despite advancements in surgical techniques and postoperative care, surgical wound infection rates have remained stagnant for three decades.
  • Nosocomial infection control is increasingly difficult due to antibiotic resistance and a growing population of high-risk elderly patients.
  • The microbiology of postoperative infections is shifting, with increased prevalence of methicillin-resistant Staphylococcus aureus (MRSA), polymicrobial flora, and fungal infections.

Purpose of the Study:

  • To review significant risk factors for surgical wound infections in general surgery.
  • To present and discuss epidemiologic data from a prospective study on wound infections.
  • To analyze trends in postoperative infection microbiology.

Main Methods:

  • A 6-year prospective study involving 4,002 patients undergoing general surgical procedures.
  • Data collection on host-related and surgical practice-related risk factors.
  • Analysis of epidemiologic data and microbiological trends in wound infections.

Main Results:

  • Identified numerous host-related and surgical practice-related risk factors contributing to wound infections.
  • Documented a changing pattern in causative agents, including MRSA, polymicrobial infections, and fungi.
  • Observed persistent high rates of surgical wound infections despite improved care.

Conclusions:

  • Surgical wound infection rates require ongoing attention and novel prevention strategies.
  • Understanding and mitigating identified risk factors are crucial for improving patient outcomes.
  • The evolving landscape of bacterial resistance and patient demographics necessitates adaptive infection control measures.
