院內感染（HAI）最主要的傳播媒介是醫護人員的手。洗手（Hand hygiene）是世界衛生組織（WHO）與美國疾病管制與預防中心（CDC）公認，預防交叉感染最關鍵、最有效的單一措施。雖然環境控制與抗生素使用有其角色，但洗手能直接移除手部暫時性菌叢，是護理師在進行任何臨床照護前必須落實的基礎動作，也是 NCLEX 考試中關於感染控制題型的首選答案。
Performing hand hygiene is the single most effective nursing action to minimize the risk of hospital-acquired infections because hands are the primary vector for pathogen transmission. While other measures like private rooms or prophylactic antibiotics have roles, consistent handwashing directly removes transient flora and prevents cross-contamination.
