[Microbiological and economic studies of abbreviated procedures for surgical hand disinfection].

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.
