To evaluate how critical nurses’ knowledge of and adherence to current care hand hygiene (HH) guidelines differ between randomly allocated intervention and control groups before and after simulation education in both a simulation setting and clinical practice during a 2-year follow-up period” Jansson et al (2016).
Background: To evaluate how critical nurses’ knowledge of and adherence to current care hand hygiene (HH) guidelines differ between randomly allocated intervention and control groups before and after simulation education in both a simulation setting and clinical practice during a 2-year follow-up period. It was hypothesized that intervention group knowledge of and adherence to current HH guidelines might increase compared with a control group after simulation education.

Methods: A prospective, parallel, randomized controlled trial with repeated measurements was conducted in a 22-bed adult mixed medical-surgical intensive care unit in Oulu, Finland. Thirty out of 40 initially randomized critical care nurses participated in the baseline measurements; of these, 17 completed all the study procedures. Participants’ HH adherence was observed only in high-risk contact situations prior to and postendotracheal suctioning events using a direct, nonparticipatory method of observation. Participants’ HH knowledge was evaluated at the end of each observational session.
Results: The overall HH adherence increased from a baseline value of 40.8% to 50.8% in the final postintervention measurement at 24 months (P = .002). However, the linear mixed model did not identify any significant group (P = .77) or time-group interactions (P = .17) between the study groups after 2 years of simulation education. In addition, simulation education had no impact on participants’ HH knowledge.
Conclusions: After a single simulation education session, critical care nurses’ knowledge of and adherence to current HH guidelines remained below targeted behavior rates.
