Uniforms are potential reservoirs for hospital organisms, potentially reinfecting the hands of health care workers (HCWs). The study aimed to determine the association between the bacterial contamination of HCWs' hands and uniforms (white coats and scrubs).
HCWs working in 5 intensive care units had cultures obtained from their hands and uniforms (white coats or scrubs). Pathogens were defined as any gram-negative bacilli, Staphylococcus aureus, and enterococci.
Bacterial growth was detected on 103 hands (86%); 13 (11%) grew S aureus, 7 (6%) grew Acinetobacter spp, 2 (2%) grew enterococci, and 83 (70%) grew only skin flora. The presence of pathogens on the hands was associated with a greater likelihood of the presence of pathogens on white coats (κ = 0.81; P < .001), but not on scrubs (κ = 0.31; P = .036). Similarly, the presence of Acinetobacter on HCWs' hands was associated with a greater likelihood of Acinetobacter contamination of white coats (κ = 0.70; P < .001), but not of scrubs (κ = 0.36; P = .024).
Contamination of provider's hands with pathogens or Acinetobacter baumannii was associated with contamination of white coats. This association was not observed between hands and scrubs, however.
制服可能是医院病原体的潜在储存库，有可能使医护人员（HCW）的手部再次感染。本研究旨在确定 HCW 手部和制服（白大衣和手术服）细菌污染之间的关联。
在 5 个重症监护病房工作的 HCW 从手部和制服（白大衣或手术服）中采集培养物。病原体定义为任何革兰氏阴性杆菌、金黄色葡萄球菌和肠球菌。
在 103 只手上检测到细菌生长（86%）；13 只（11%）生长金黄色葡萄球菌，7 只（6%）生长不动杆菌属，2 只（2%）生长肠球菌，83 只（70%）仅生长皮肤菌群。手部存在病原体与白色大衣上存在病原体的可能性更大相关（κ=0.81；P<.001），但与手术服无关（κ=0.31；P=.036）。同样，HCW 手上不动杆菌的存在与白色大衣上不动杆菌污染的可能性更大相关（κ=0.70；P<.001），但与手术服无关（κ=0.36；P=.024）。
病原体或鲍曼不动杆菌污染提供者的手与白色大衣的污染有关。然而，这种关联在手和手术服之间没有观察到。
