Year: 2025
Type: article
Study design: Observational Study
Abstract: Introduction: An infection is classified as a healthcare-associated infection (HAI) if it happens on or after the third calendar day of admission to an inpatient facility where the date of admission is a calendar day, according to the NHSN (National Healthcare Safety Network) site-specific infection criterion. Aims: To evaluate SSI caused by S. aureus including its drug-resistant isolates. To find relation if any between nasal carriage of S. aureus and occurrence of SSI caused by S. aureus. Materials & Methods: It was an institutional-based, descriptive study. The present study was conducted in the department of Microbiology and Department of Surgery, Bankura Sammilani Medical College and Hospital, Bankura, India. The duration of the study was for a period of twelve months from February 2015 to January 2016 Result: In our study, nasal carriage of methicillin-sensitive Staphylococcus aureus (MSSA) was present in 364 out of 591 patients (61.6%), with the association found to be statistically significant (p < .00001). In our study, surgical site infections (SSI) caused by Staphylococcus aureus were observed in 101 out of 336 patients (30%), with the association being statistically significant (p < .00001). Conclusion: We concluded that the incidence of surgical site infections (SSI) brought on by Staphylococcus aureus in a tertiary care hospital is significantly correlated with nasal carriage of this bacterium, according to this study. Of the 1600 postoperative patients, 336 had SSI, and 364 of the 591 patients were nasal carriers of MSSA.
