Introduction: The spread of multidrug-resistant microorganisms, such as methicillin-resistant Staphylococcus aureus (MRSA), is a critical challenge to healthcare safety, particularly in the General Emergency Department, due to high patient turnover and clinical complexity. Active surveillance and the implementation of control measures are essential to limit the spread of these agents.
Objectives: To assess the prevalence of MRSA colonization among patients admitted to the GED in 2024, identify associated risk factors, compare with previous data, and propose recommendations to improve nursing practices in infection prevention and control.
Methods: A descriptive, cross-sectional, and retrospective study was conducted, analyzing 810 screenings of patients admitted to the Short-Stay Unit. Clinical, epidemiological, and laboratory data were collected, complemented by monthly audits and training sessions for the nursing team. Descriptive statistics were applied.
Results: The prevalence of MRSA colonization was 12.6%, lower than the national average (25%). Main risk factors included previous hospitalization (30%), institutionalization (29%), and recent antibiotic use (16.6%). A significant increase in screenings was observed after staff training.
Conclusion: Active surveillance strategies, staff training, and integration of clinical protocols proved effective in reducing MRSA rates and promoting patient safety in the General Emergency Department.
