手部衛生是預防醫療照護相關感染（Healthcare-Associated Infections, HAIs）最有效且經濟的手段。根據 CDC 及 WHO 指南，使用肥皂與水洗手時，搓揉手部時間必須達到 20 秒，這是透過物理摩擦與化學作用移除暫時性微生物的最低門檻。護理師必須確保教導病患此標準，以強化居家照護的感染控制能力。
The Centers for Disease Control and Prevention (CDC) recommends washing hands with soap and water for at least 20 seconds to effectively remove transient microorganisms. This duration allows sufficient time for the mechanical friction and chemical action needed to break down pathogens and dirt. Shorter durations are insufficient for adequate decontamination, while longer times exceed the minimum standard requirement.
