确定北方爱尔兰一个地理上确定的卫生行政区域内养老院居民和工作人员中耐甲氧西林金黄色葡萄球菌（MRSA）定植的患病率及其相关因素。点患病率研究。养老院。养老院居民和工作人员。从所有同意的居民和工作人员中采集鼻拭子。如果相关，居民还提供尿液样本，并从伤口和留置装置中提取拭子。45家养老院的1,111名居民（占所有居民的66%）和553名工作人员（占可用工作人员的86%）参与了调查。MRSA在常住人口中的合并患病率为23.3%（95%置信区间（CI）=18.8-27.7%），在工作人员中的合并患病率为7.5%（95% CI=5.1-9.9%）。居住在连锁养老院的居民比居住在独立设施的居民更容易感染MRSA（比值比（OR）=1.91，95%CI =1.21-3.02）。如果居民居住的家庭中超过12.5%的接受过筛查的医护人员，（护理助理和护士）被MRSA定殖（OR=2.46，95% CI=1.41-4.29）或如果他们居住在超过15%的护理助理被MRSA定植的家中OR=2.64，95% CI=1.58-4.42，提示本地区养老院居民和工作人员中MRSA定植率较高。实施感染控制策略应给予高度重视，在养老院。
To determine the prevalence of, and factors associated with, methicillin-resistant Staphylococcus aureus (MRSA) colonization in residents and staff in nursing homes in one geographically defined health administration area of Northern Ireland.Point prevalence study.Nursing homes.Residents and staff in nursing homes.Nasal swabs were taken from all consenting residents and staff. If relevant, residents also provided urine samples, and swabs were taken from wounds and indwelling devices.A total of 1,111 residents (66% of all residents) and 553 staff (86% of available staff) in 45 nursing homes participated. The combined prevalence rate of MRSA in the resident population was 23.3% (95% confidence interval (CI)=18.8-27.7%) and 7.5% in staff (95% CI=5.1-9.9%). Residents who lived in nursing homes that were part of a chain were more likely to be colonized with MRSA (odds ratio (OR)=1.91, 95% CI=1.21-3.02) than those living in independently owned facilities. Residents were also more likely to be colonized if they lived in homes in which more than 12.5% of all screened healthcare staff (care assistants and nurses) were colonized with MRSA (OR=2.46, 95% CI=1.41-4.29) or if they lived in homes in which more than 15% of care assistants were colonized with MRSA (OR=2.64, 95% CI=1.58-4.42).The findings suggest that there is substantial colonization of MRSA in nursing home residents and staff in this one administrative health area. Implementation of infection control strategies should be given high priority in nursing homes.
