Hand hygiene (HH) compliance can be affected by the accessibility of products (alcohol-based products or chlorhexidine) and by the formulations of these products. There are few published studies comparing different alcohol-based hand disinfection formulations.
This study was conducted in a 41-bed medical-surgical intensive care unit at a private tertiary care hospital. Over a 16-week period, we assessed HH compliance by direct observation of practice using iPods and measurement of the amount of product used [alcohol and chlorhexidine] in two 4-room pods in which an alcohol gel product was used compared with two other 4-room pods in which an alcohol-based foam formulation was used.
A total of 3,895 opportunities for HH were observed, and the overall rate of HH compliance was 36.9%. No statistically significant differences were found in overall HH compliance or alcohol-based HH compliance between the alcohol foam unit and the alcohol gel unit. However, there was a statistically significant difference in chlorhexidine HH compliance between the alcohol foam unit and the alcohol gel unit (7.0% [130 of 1,853] vs 3.8% [77 of 2,042]; P < .01).
Alcohol handrub use was greater than chlorhexidine use, but HH compliance was low in both units independent of the alcohol formulation available. The similarity of use of both alcohol formulations suggests that health care workers tend to use whatever product is readily available.
手卫生（HH）的依从性可能会受到产品（醇基产品或洗必泰）的可及性以及这些产品配方的影响。目前，比较不同醇基手部消毒配方的已发表研究较少。
本研究在一家私立三级护理医院的 41 张病床的内科-外科重症监护病房进行。在 16 周的时间里，我们通过使用 iPod 直接观察实践情况和测量两种 4 室荚中的产品用量[酒精和洗必泰]，评估 HH 的依从性，这两种荚中一种使用酒精凝胶产品，而另两种使用醇基泡沫制剂。
共观察到 3895 次 HH 机会，HH 总依从率为 36.9%。在酒精泡沫单元和酒精凝胶单元之间，总体 HH 依从率或基于酒精的 HH 依从率没有统计学上的显著差异。然而，在酒精泡沫单元和酒精凝胶单元之间，洗必泰 HH 依从率存在统计学上的显著差异（7.0%[130/1853]与 3.8%[77/2042]；P<.01）。
酒精洗手液的使用量大于洗必泰，但两个单元的 HH 依从性均较低，与可用的酒精配方无关。两种酒精配方的使用相似性表明，医护人员倾向于使用任何易于获得的产品。
