老人ホームにおけるMRSA対策

Methicillin-Resistant Staphylococcus aureus in a Home for the Aged

　特別養護老人ホームA寮における現在のMRSA汚染度を知り，今後の本施設におけるMRSA対応策を検討するために，MRSA汚染度調査を行った．1996（平成8）年2月13日における全273ヵ所（老人と職員の手および環境）の調査では,MRSAは環境の3ヵ所のみから検出され，検出菌量もごく少量だったので，3月1日より特別のMRSA対策をすべて止めた．次いで，3月6日，13日とMRSA調査を行った．その結果は，環境および老人の手からのMRSA検出率はほとんど変わらなかったが，それまでまったくMRSAが検出されなかった職員のうち13日に入浴介助を行った5人の職員の手からMRSAが検出された．入浴介助時に老人からの汚染が考えられたので，入浴介助後の手洗いの励行と浴室および，そのまわりの清掃（時々消毒剤を用いる）に特に注意すること，また日常の各種介護後の手洗いを励行することにした．

　We examined MRSA (Methicillin-resistant Staphylococcus aureus) colonization of the residents, staff and environment at A-Ryo, a home for the aged 3 times. The first examination was performed on 70 residents, 40 staffs and 163 sites of this home on Feb. 13, 1996. All samples were taken by a contact plate method. Of 273 samples, three were MRSA positive, and they had few numbers of MRSA colonies. In addition, all of them were not from persons but from the home environment such as corridor floor. So, the staff stopped doing anything against MRSA contamination on Mar. 1. The second examination was conducted on Mar. 6, and the third on Mar. 13. The MRSA detection rates of the residents and environment were respectively low, and didn't show remarkable change between 2 examinations. However, at the third examination MRSA were detected from the hands of 5 staffs who do bathing for the residents. Therefore, we recommended that staffs should wash their hands and keep bath clean after bathing.
