背景资料：通过医护人员的手的微生物交叉传播被认为是医院感染传播的主要途径。目的：研究大型教学医院在常规病人护理过程中医护人员手的细菌污染过程。和V.S.）。每个观察期从洗手程序后开始，到卫生保健工作者开始洗手或连续护理结束时结束。在每个观察期结束时，取惯用手5个指尖的印记，并定量细菌菌落计数。回归方法被用来模拟细菌污染的强度作为一个功能的方法的手清洁，使用手套在病人护理，持续时间和类型的护理，和hospital ward.Results的细菌污染线性增加，在病人护理（平均，16个菌落形成单位[CFU]每分钟，95%的置信区间，11-21 CFU每分钟）不戴手套的手的时间。独立开展患者护理活动（P
Background: Cross-transmission of microorganisms by the hands of health care workers is considered the main route of spread of nosocomial infections.Objective: To study the process of bacterial contamination of health care workers' hands during routine patient care in a large teaching hospital.Methods: Structured observations of 417 episodes of care were conducted by trained external observers (S.T. and V.S.). Each observation period started after a hand-cleansing procedure and ended when the health care worker proceeded to clean his or her hands or at the end of a coherent episode of care. At the end of each period of observation, an imprint of the 5 fingertips of the dominant hand was taken and bacterial colony counts were quantified. Regression methods were used to model the intensity of bacterial contamination as a function of method of hand cleansing, use of gloves during patient care, duration and type of care, and hospital ward.Results Bacterial contamination increased linearly with time on ungloved hands during patient care (average, 16 colony-forming units [CFUs] per minute; 95% confidence interval, 11-21 CFUs per minute). Patient care activities independently (P
