Implicit attitude towards hand hygiene as relevant predictor of hand hygiene behaviour

Background: Hand disinfection is one of the key measures to prevent nosocomial infections. However, compliance with hygienic hand disinfection still is poor, both nationally and internationally. This study examined the influence of touchless disinfectant dispensers on the compliance with hand disinfection.

Methods: The observational study was conducted in an intensive care unit of the University Hospital Aachen, Germany. During an initial 8-week baseline phase, the consumption of hand disinfectant was assessed by common dosing dispensers equipped with electronic counters. Weekly evaluation was carried out by considering the dispenser location. After this phase, all disinfectant dispensers were replaced by sensor-controlled dispensers with integrated counter. During the subsequent study phase of 12 weeks, the consumption was again monitored and assessed weekly.

Results: An average of 34 hand disinfection procedures per patient day were carried out during the baseline phase. After the introduction of the touchless dispensers, the average was 52 hand disinfection procedures per patient day. Thus, the number of hand disinfection procedures increased by 53 per cent. Near-patient dispensers were used twice as much as those installed in corridors. The increased consumption remained constant over the entire 12-week observation period.

Conclusions: The results of this observational study demonstrate that the use of sensor-controlled disinfectant dispensers improves the consumption while at the same time being cost efficient.
