COMPARATIVE STUDY OF NOSOCOMIAL INFECTION RATES BEFORE AND AFTER IMPLEMENTATION OF STANDARD OPERATING PROCEDURES IN THE SURGICAL CENTER OF THE MUNICIPAL HOSPITAL OF MARABÁ- PA

Abstract

Objective: To evaluate the rates of nosocomial infection before and after the implementation of Standard Operating Procedures (SOPs) in the operating room of a municipal hospital. Methods: This is an epidemiological, cohort, quantitative and analytical study that was carried out in a medium-sized municipal hospital, analyzing retrospective and prospective data over a period of 12 months. Information was collected on cases of surgical site infection in the period of 06 months before the implementation of the SOPs in the months of February to July 2024 and in the 06 months following until January 2025. Infection rates were compared by applying the independent Student's t-test. Data on surgical site infection (SSI) over 12 months were analyzed, divided into periods before and after the implementation of the protocols. Results: The results indicate a statistically significant reduction in infection rates after the implementation of standard operating procedures in the operating room, demonstrating the effectiveness of standardization of processes in infection prevention and control. Conclusion: The adoption of Standard Operating Procedures in the operating room is essential to reduce the incidence of nosocomial infections, ensuring safe and efficient patient care. The standardization of processes, strict infection control, reduction of errors, and constant training are fundamental pillars for safety in the surgical environment.
