Gloves are a necessary contact precaution to prevent transmission of infectious pathogens that spread by direct or indirect contact with an infected person or a contaminated environment. This article reports a study investigating hand and environmental contamination levels when health care workers (HCWs) followed two different methods of removing gloves at two distances from the rubbish bin.
Fifty HCWs performed a personal or causal glove removal method (pretest) and a Centers for Disease Control (CDC)-recommended glove removal method (posttest) at distances of 2 feet and 3 feet from the rubbish bin after the application of fluorescent solution (the simulated contaminant) onto their gloved hands.
The incidence of the small patch of fluorescent stain (<1 cm(2)) on the front of the doffed gloves was significantly lower in the posttest than in the pretest. The incidence of small and large patches (>1 cm(2)) on the front of the doffed gloves and on the cover of the rubbish bin was significantly lower at 3 feet than at 2 feet. Health care assistants had significantly higher levels of contamination than other HCWs in the pretest but not in the posttest. There was no significant difference in hand contamination rate between pretest and posttest based on distance from the rubbish bin and type of HCW.
The impact of the glove removal procedure and the distance to the bin in which used gloves are discarded should be taken into consideration on a daily basis, along with the supervision of infection control measures by minor staff.
手套是预防通过直接或间接接触感染人员或受污染环境传播的传染性病原体的必要接触预防措施。本文报道了一项研究，该研究调查了当医护人员（HCW）从距离垃圾桶 2 英尺和 3 英尺的两个距离使用两种不同的脱手套方法时，手和环境的污染水平。
50 名 HCW 在他们的手套上应用荧光溶液（模拟污染物）后，分别进行个人或因果手套去除方法（预测试）和疾病控制与预防中心（CDC）推荐的手套去除方法（后测试），距离垃圾桶 2 英尺和 3 英尺。
与预测试相比，在后测试中，脱手套正面的小荧光斑（<1 cm(2))的发生率明显降低。脱手套正面和垃圾桶盖的小面积和大面积（>1 cm(2))的发生率在后测试中距离 3 英尺时明显低于距离 2 英尺时。在预测试中，医疗助理的污染程度明显高于其他 HCW，但在后测试中则不然。根据距离垃圾桶的距离和 HCW 的类型，预测试和后测试之间的手部污染率没有显著差异。
应在日常工作中考虑手套去除程序和丢弃使用过的手套的垃圾桶的距离的影响，以及对感染控制措施的监督。
