預防院內感染（HAI）的核心在於切斷病原體的傳播途徑。手部衛生（Hand hygiene）被世界衛生組織（WHO）與美國 CDC 公認為預防 HAI 最有效、經濟且具廣泛影響力的措施。微生物主要透過醫護人員的手部在病人之間交叉傳播，落實「洗手五時機」能有效降低感染風險。其他選項僅能針對特定接觸或環境，無法取代手部衛生在預防感染上的全面性效益。
Performing hand hygiene is the single most effective measure for preventing healthcare-associated infections because it interrupts the primary mode of pathogen transmission between patients and healthcare workers. While sterile gloves and gowns have specific indications, they are not required for routine assessments or all patient encounters. Limiting visitors may reduce exposure but does not replace the fundamental importance of strict hand hygiene compliance.
