Purpose: The purpose of this study was to analyze effects of hand drying methods after hand-washing. Hand drying methods consisted of spontaneous evaporation, paper towel, hand dryer with rubbing, and hand dryer without rubbing.
Methods: The research design was a crossover design. The subjects were eighteen university students and randomly assigned in four group. Each group had the schedule of treatment. The schedule tested one drying method per a day and proceeded for 4 days. The data collection was performed from July 27 to July 30, 2010. Data were analyzed by Kruskal-Wallis, Mann-Whitney and Wilcoxon test.
Results:There was significant difference between the after CFU between natural dry, paper towel, air dryer with hand rubbing, and air dryer without hand rubbing(p=.006). The after CFUs of paper towel, natural dry and air dryer without hand rubbing groups were statistically less than air dryer with and rubbing group.
Conclusion:It was shown that the paper towel, spontaneous evaporation and without rubbing hand dryer are effective hand drying interventions on reducing CFU on hand. However additional researches with large sample and strict methodology are needed.
