Efficient hand hygiene is essential for preventing the transmission of microorganisms. Alcohol-based hand rub (ABHR) is a recommended method. We compared health personnel (skilled nurse students) with random adults to study the effect of an ABHR procedure. A water-based hand rub (WBHR) procedure, using running tap water and a hand-drying machine, was also investigated. The study included 27 nurse students and 26 random adults. Hands were contaminated with , and concentrations of colony forming units (CFU/mL) were determined before and after ABHR or WBHR. Concentrations after ABHR were 1537 CFU/mL (nurse students) and 13,508 CFU/mL (random adults) ( < 0.001). One-third of participants reported skin irritation from daily ABHR. Concentrations after WBHR were 41 CFU/mL (nurse students) and 115 CFU/mL (random adults) ( < 0.011). The majority of participants (88.5%) preferred the WBHR method. Results from 50 air samples from filtered air from the hand dryer outlet showed no CFU in 47 samples. A significant difference between the two groups was shown for the ABHR method, indicating that training skills are important for efficient hand hygiene. Surprisingly, the WBHR method seemed to have a significant effect in largely removing transient bacteria from hands.
有效的手部卫生对于预防微生物传播至关重要。酒精擦手液（ABHR）是一种推荐的方法。我们将卫生人员（专业护士学生）与随机选取的成年人进行比较，以研究ABHR程序的效果。还研究了一种使用流动自来水和干手器的水基擦手液（WBHR）程序。该研究包括27名护士学生和26名随机选取的成年人。双手被污染后，在进行ABHR或WBHR前后测定菌落形成单位（CFU/mL）的浓度。ABHR后的浓度分别为1537 CFU/mL（护士学生）和13508 CFU/mL（随机选取的成年人）（<0.001）。三分之一的参与者报告称每天使用ABHR会导致皮肤刺激。WBHR后的浓度分别为41 CFU/mL（护士学生）和115 CFU/mL（随机选取的成年人）（<0.011）。大多数参与者（88.5%）更喜欢WBHR方法。从干手器出风口过滤空气中采集的50个空气样本中，47个样本未检测到CFU。ABHR方法在两组之间显示出显著差异，表明培训技能对于有效的手部卫生很重要。令人惊讶的是，WBHR方法似乎在很大程度上去除手部暂居细菌方面有显著效果。
