頭頸部外科病棟におけるMRSAアウトブレイクと感染予防策

抄録

We report a case of outbreak with Methicillin-resistant Staphylococcus Aureus (MRSA) in our division. Seven patients were involved in this case. All patients were of head and neck cancer and their infection patterns showed two of different antimicrobial resistance. We executed three strategies to solve this problem. First, to survey a ratio of germ carrier, then second, to close the outbreak ward, and finally to reformulate the protocol for infection precaution. In these strategies, to formulate the infection precaution is extremely important, due to the high risk of infection for many immune failed patients, especially in the head and neck surgery. Infection expands by human factors, material factors, and environmental factors. In the new protocol for infection, we applied each countermeasures in form in conformity with CDC guidelines. We spent two months to control the outbreak with full cooperation of all over hospital. Time limitation, understaffing, and other problems such as the technical acquisition stand in the way for fixation of this protocol. It will be necessary to inspect problem and effectiveness of new protocol in future.
