分析各種紫外線模式運用於醫院環境清潔消毒

Analysis of various ultraviolet models used in environmental cleaning

面對疫情，醫療體系的感染預防與感染控制是阻絕或降低交叉感染的重要防 線，醫院環境的潔淨程度已經是目前醫療照護相關感染重要的議題之一。醫院環 境的潔淨程度在許多研究後顯示跟改善醫療照護感染有正面相關。然僅靠既有的 環衛清潔人力，以單純勞力維護環境清潔與消毒，要維持醫院全面性高品質的安 全環境及阻絕病菌散播是困難的，在許多國家醫院感染控制，運用漂白水「手動 清潔」，和紫外線 UV-C 消毒，四級氨消毒劑，脈衝氙紫外線等等研究仍有可再 討論的空間。整個防疫是需要策略的，醫療端佈下天羅地網來加以因應，全方位 的整體防疫策略期望在面對總總未知的疫情控制與醫院環境安全品質的提昇能有 所助益。（感控雜誌 2020:30:249-258）

Infection prevention and infection control in the medical system are important to reduce cross-infection. Environment cleaning has become one of the most important ways of reducing healthcare-associated infections. It has shown to be positively related to improving the quality of medical care. However, it is difficult for the personnel in charge of cleaning to maintain the cleanliness and disinfection of the environment and hence a high-quality clean environment in the hospital. In many institutions, hospital infection control programs use non-touch disinfection methods, such as ultraviolet C disinfection, four-level ammonia disinfectant, and pulsed xenon ultraviolet. Infection prevention strategies are important to improve and maintain a clean hospital environment.
