An investigation was performed of whether shortened procedures for surgical hand disinfection (2 and 3 min, respectively) are equally effective as the usual German standard procedure of 5 min duration and, in addition, which saving of working time and costs would be achievable if shorter procedures were employed. The shortened procedures were: 1) 3 min alcoholic disinfectant (1 min prior handwashing) and 2) 1 min chlorhexidine detergent (Hibiscrub), 2 min 0.5% chlorhexidine in 70% isopropanol (Hibisol). The two shortened procedures were equally effective as the standard procedure (test of equivalence, p < 0.05). The savings of working time and costs calculated for 17708 operations were 1) 2360 h or 79768 German marks and 2) 3540 h or 119652 German marks, respectively.
针对手术手部消毒的缩短流程（分别为2分钟和3分钟）是否与德国通常的5分钟标准流程同样有效进行了一项调查，此外，如果采用缩短流程，能节省多少工作时间和成本。缩短流程如下：1）3分钟酒精消毒剂消毒（洗手前1分钟），以及2）1分钟洗必泰洗涤剂（ Hibiscrub），2分钟70%异丙醇中的0.5%洗必泰（ Hibisol）。这两种缩短流程与标准流程同样有效（等效性检验，p<0.05）。针对17708例手术计算得出的工作时间和成本节省分别为：1）2360小时或79768德国马克，以及2）3540小时或119652德国马克。
