醫院環境及設備消毒以預防COVID-19感染之探討

Environmental disinfection at hospitals as a strategy for COVID-19 spread prevention

摘要


目標:醫院公共環境設備或接觸面是最常被忽略預防感染重要點,藉由清潔頻率探討,達到COVID-19疫情期間預防感染及避免感染擴散的目的。方法:本研究採取ATP冷光反應檢測法,來量化醫院公共環境設備或接觸面環境污染的程度,以反應不同實際清潔頻率所達到的效果。結果:實證發現依照常規清潔及加強清潔頻率,如一般預測有不同檢測結果。常規清潔無法符合文獻建議較嚴格小於250RLU的標準。結論:於COVID-19疫情期間之上班時段對一般人頻繁接觸的物體表面清潔消毒頻率應提高至每2小時一次,並定時監測及將結果反應給清潔人員,同時支持嚴格遵守環境和手部衛生的要求,以達到COVID-19感染控制之目標。

Objectives: Cleanliness of hospitals' public environmental equipment or contact surfaces are frequently overlooked in the prevention of COVID-19. This paper discusses the cleaning frequency, with the purpose of preventing COVID-19 infection and controlling its dissipation during the pandemic. Methods: Using the ATP cold light reaction detection method, we quantified the degree of pollution in hospitals' public environmental equipment or contact surfaces to reflect the effect of actual cleaning frequency. Results: Empirical findings indicated that according to the conventional cleaning and enhanced cleaning frequency, different test results are expected as generally predicted. Routine cleaning cannot meet the standard recommended in the literature (i.e., <250 RLU). Conclusions: During the COVID-19 pandemic, the frequency of cleaning and disinfecting surfaces of objects frequently contacted by general public should be increased to every 2 hours. Moreover, these results should be regularly monitored and reflected to the cleaning staff, so that they can support strict compliance with environmental and hand hygiene to meet infection control goals for COVID-19.
