The duration of colonization with methicillin-resistant Staphylococcus aureus is not well defined. During 1564 admissions after a clinical culture or surveillance test positive for methicillin-resistant Staphylococcus aureus, we retested patients for methicillin-resistant Staphylococcus aureus colonization. During the first year after the positive culture result was obtained, 48.8% of the patients (95% confidence interval, 45.8%-51.7%) remained colonized; at 4 years, 21.2% of the patients (95% confidence interval, 13.1%-31.4%) remained colonized.
耐甲氧西林金黄色葡萄球菌的定植持续时间尚无明确界定。在1564例临床培养或监测检测结果为耐甲氧西林金黄色葡萄球菌阳性的入院患者中,我们对这些患者再次进行了耐甲氧西林金黄色葡萄球菌定植检测。在获得阳性培养结果后的第一年,48.8%的患者(95%置信区间为45.8%-51.7%)仍处于定植状态;4年后,21.2%的患者(95%置信区间为13.1%-31.4%)仍处于定植状态。
