預防醫療照護相關感染（Healthcare-Associated Infections, HAIs）的核心在於切斷傳播途徑。手部衛生（Hand Hygiene）是證據等級最高、最經濟且最有效的感染控制手段。根據疾病管制與預防中心（CDC）指引，護理師應在接觸病人前後、執行清潔或無菌操作前、接觸體液後以及接觸病人周遭環境後，嚴格執行手部衛生，以防止微生物透過雙手交叉傳播。
Frequent hand hygiene is the single most effective intervention for preventing healthcare-associated infections, as it directly interrupts the transmission of microorganisms. Other measures like wearing gloves or limiting visitors are supportive but do not replace the fundamental importance of proper hand cleaning.
