Median (IQR) number of hand disinfection events per healthcare worker plotted for each hour of the day, calculated over the one-year study period. Analysis of hand disinfection events per healthcare worker by hour of the day revealed a significant increase in hand disinfection events from 8:00 h to 10:00 h, which coincides with the start of the dayshift and medical assessments. Another increase was found from 16:00 h to 19:00 h, which correspondents with elevated activities before dinnertime (p < 0.001 for both). The number of hand disinfection events was relatively low from 10:00 h to 16:00 h.
