Perianal screening can be intrusive. The sensitivities of multianatomical, nonperianal surveillance were 92.3% for methicillin-resistant (MRSA), 58.7% for vancomycin-resistant enterococci (VRE), and 54.9% for resistant Gram-negative bacilli (R-GNB). Sensitivities improved upon adding environmental surveillance (95.5%, 82.9%, and 67.9%, respectively). Multianatomical, nonperianal screening and room environment surveillance may replace perianal screening and reduce healthy participant bias in nursing homes.
肛周筛查可能具有侵入性。多解剖部位、非肛周监测对耐甲氧西林金黄色葡萄球菌（MRSA）的敏感度为 92.3%，对万古霉素耐药肠球菌（VRE）为 58.7%，对耐药革兰氏阴性杆菌（R-GNB）为 54.9%。通过增加环境监测，其敏感度分别提高到 95.5%、82.9%和 67.9%。多解剖部位、非肛周筛查和房间环境监测可能替代肛周筛查，并减少养老院中健康参与者的偏倚。
