RESUMO
BACKGROUND: 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. METHODS: 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. RESULTS: 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). CONCLUSIONS: 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.
