Methicillin-resistant Staphylococcus aureus (MRSA) is a common cause of healthcare-related infection. Surveillance and prevention of MRSA is a priority in infection control programs. The aim of this study was to describe rates and trends of MRSA colonization or infection in 40 hospitals participating in the VINCat Program from 2008 to 2010. The study included all patients treated in acute care areas of participating hospitals. Hospitals were stratified into 3 groups based on size. The following annual indicators were reported: Methicillin-resistance rate, incidence density of new cases of MRSA and incidence density of MRSA bacteremia. Between 2008 and 2010, the yearly mean rate of resistance to methicillin remained stable for the study period (24%-25%), while the mean incidence of new cases of MRSA decreased from 0.65 to 0.54 cases per 1000 patient-days (p=NS) and the mean incidence of MRSA bacteremia decreased from 0.06 to 0.05 cases per 1,000 patient-days (p=NS). The implementation of a MRSA surveillance system in hospitals that participated in the VINCat Program provides information on the situation of each institution and facilitated interhospital comparisons in order to establish appropriate preventive measures.
耐甲氧西林金黄色葡萄球菌（MRSA）是一种常见的医源性感染病原体。对 MRSA 的监测和预防是感染控制计划的重点。本研究的目的是描述 2008 年至 2010 年参加 VINCat 计划的 40 家医院中 MRSA 定植或感染的发生率和趋势。本研究包括参加医院急性护理区治疗的所有患者。根据规模将医院分为 3 组。报告了以下年度指标：耐甲氧西林金黄色葡萄球菌的耐药率、新发病例的发病率密度和耐甲氧西林金黄色葡萄球菌菌血症的发病率密度。2008 年至 2010 年间，研究期间耐甲氧西林金黄色葡萄球菌的年平均耐药率保持稳定（24%-25%），而新发病例的发病率从 0.65 例/1000 患者天降至 0.54 例/1000 患者天（p=NS），耐甲氧西林金黄色葡萄球菌菌血症的发病率从 0.06 例/1000 患者天降至 0.05 例/1000 患者天（p=NS）。参加 VINCat 计划的医院实施了耐甲氧西林金黄色葡萄球菌监测系统，为每个机构的情况提供了信息，并促进了医院间的比较，以便制定适当的预防措施。
