防止感染傳播最簡單、最有效的方法就是「手部衛生（Hand Hygiene）」。無論是進行傷口換藥、給藥或身體評估，護理師在接觸病人前後都必須落實洗手。手部衛生能有效中斷病原體在醫護人員與病人之間的交叉感染鏈。其他選項如穿著無菌衣或使用 N95，需視傳染途徑與無菌技術要求而定，並非所有傷口換藥都需如此高規格的防護。
Hand hygiene before and after wound care is the single most effective and universally applicable measure to prevent healthcare-associated transmission. Sterile gowns are reserved for surgical/sterile procedures; routine dressing changes use clean technique unless specifically ordered otherwise. Dressing frequency is determined by drainage and orders, not arbitrary hourly schedules. N95 respirators are for airborne pathogens, not contact-spread wound infections.
