The duration of handwashing was studied in two community hospitals (teaching and nonteaching). The duration in seconds of 180 handwashes by health care personnel and 52 handwashes by non-health care personnel were recorded. The mean duration for health care personnel was 8.62 +/- 0.29 SEM; the degree of patient contact did not influence the duration of handwashing. The duration of handwashing was two times longer in health care personnel vs. non-health care personnel (8.62 +/- 0.29 vs. 4.14 +/- 0.42; t = 7.7; p less than 0.001). Comparisons revealed no statistically significant difference in duration between personnel at teaching and nonteaching hospitals or among those in different occupations. The data indicate that the duration of handwashing among health care personnel is below the standard recommended by authorities in hospital infection control. This may be an important factor in the transmission and persistence of nosocomial infection in critical care units. The antimicrobial efficacy of handwashing agents should be reevaluated considering the actual duration of handwashing by health care personnel within the hospital environment or efforts should be made to increase the duration of handwashing.
在两家社区医院（教学医院和非教学医院）对洗手时长进行了研究。记录了医护人员的180次洗手时长（以秒为单位）以及非医护人员的52次洗手时长。医护人员的平均洗手时长为8.62±0.29标准误；与患者接触的程度并未影响洗手时长。医护人员的洗手时长是非医护人员的两倍（8.62±0.29对比4.14±0.42；t=7.7；p<0.001）。比较结果显示，教学医院和非教学医院的人员之间或不同职业人员之间在洗手时长上无统计学显著差异。数据表明，医护人员的洗手时长低于医院感染控制当局推荐的标准。这可能是重症监护病房医院感染传播和持续存在的一个重要因素。应根据医护人员在医院环境中的实际洗手时长重新评估洗手剂的抗菌效果，或者应努力增加洗手时长。
