From: The effect of training and awareness of subtle control on the frequency of hand hygiene among intensive care unit nurses

Moments of hand hygiene compliance Control group Intervention group P-value
Mean ± SD Mean ± SD
Before touching a patient 9.2 ± 28 8.2 ± 23.2 0.02
Before a clean/aseptic procedure 10.4 ± 18.5 23.5 ± 17.2 0.03
After body fluid exposure risk 5.1 ± 15.2 8.9 ± 20.6 0.36
After touching a patient 10 ± 22.5 16.5 ± 16 0.30
After touching patient surroundings 6.0 ± 14 5.5 ± 14.4 0.73
Total 7.7 ± 10.7 17.4 ± 6.9 0.001
  1. The mean difference percentage = (mean percentage of hand hygiene compliance after the intervention) − (mean percentage of hand hygiene compliance before the intervention)
  2. Mann–Whitney U was used
