  Purpose

This is a randomized controlled trial comparing the effectiveness of three hand hygiene protocols, during routine inpatient clinical care: Protocol 1: handrubbing with alcohol covering all hand surfaces in no particular order; Protocol 2: handrubbing with alcohol using the WHO standard 7-step technique; and Protocol 3: handwashing with chlorhexidine using the WHO standard 7-step technique.

The main study hypothesis is that alcohol hand-rubbing covering all hand surfaces is not less effective in reducing bacterial hand contamination of healthcare staff than alcohol hand-rubbing using 7-step technique; and is more effective than chlorhexidine handwashing. The secondary study hypothesis is that time spent on alcohol hand-rubbing covering all hand surfaces is less than that required by the other 2 hand hygiene protocols respectively.

Primary Outcome Measures:
  • reduction of hand bacterial load [ Time Frame: hand samples will be analyzed up to 11 months after collection; data will be presented for an average of 5 years after data collection ] [ Designated as safety issue: No ]
    The primary outcome measure of the study was to ascertain the effectiveness of the three hand-hygiene protocols, in the reduction of hand bacterial load. Quantitative reduction in bacterial load will be measured in colony forming units per mililiter (cfu/ml). Bacteria will be qualitatively identified, and sensitivity to antibiotics determined.


Secondary Outcome Measures:
  • time spent on hand hygiene [ Time Frame: participants will be observed for the duration of hand hygiene; data will be presented for an average of 5 years after data collection ] [ Designated as safety issue: No ]
    The secondary outcome measure include the estimation of time spent on hand hygiene, for each hand hygiene protocol. Time will be measured in seconds.
