Nasal Staphylococcus aureus and postoperative infection

    Summary

    Preoperative nasal Staphylococcus aureus (S. aureus) colonization was common in patients but did not increase postoperative infection risk. S. aureus remains a significant cause of hospital-acquired infections.

    Area of Science:

    • Infectious Diseases
    • Hospital Epidemiology
    • Surgical Site Infections

    Background:

    • Staphylococcus aureus (S. aureus) is a major cause of nosocomial infections.
    • Prolonged preoperative hospital stays are known risk factors for infectious complications.
    • The role of preoperative nasal S. aureus colonization in postoperative infection risk requires further elucidation.

    Purpose of the Study:

    • To investigate the prevalence of preoperative nasal S. aureus colonization in patients.
    • To determine the correlation between nasal S. aureus carriage and the incidence of postoperative infections.
    • To assess the impact of preoperative hospital stay length on S. aureus colonization and infection rates.

    Main Methods:

    • Prospective study over a one-year period.
    • Screening of 237 patients for preoperative nasal S. aureus carriage.
    • Analysis of the relationship between nasal colonization, hospital stay duration, and postoperative infection rates.

    Main Results:

    • 19.5% of 237 patients were preoperative nasal carriers of S. aureus.
    • Nasal S. aureus carriage was not influenced by the length of hospital stay.
    • No correlation was found between patient nasal carrier state and postoperative infection incidence.
    • S. aureus accounted for 19% of all postoperative infections during the study period.

    Conclusions:

    • Preoperative nasal S. aureus colonization does not appear to increase the risk of postoperative infections.
    • Despite the lack of correlation with colonization, S. aureus remains a significant pathogen in hospital-acquired infections.
    • Hospital infection control strategies should continue to address S. aureus prevention.
