The impact of the hand hygiene role model project on improving healthcare workers' compliance: A quasi-experimental observational study. | LitMetric

AI Article Synopsis

Article Abstract

Background: The World Health Organization (WHO)'s multimodal strategy for improving hand hygiene (HH) compliance was endorsed in 2009 and was implemented by every hospital in Oman. There was variation in adherence to the practice even within the same facility and in sustaining improvement after the intervention.

Objectives: Evaluate the impact of national HH role model project on health care worker's immediate and long term compliance with HH practices.

Material And Methods: A pretest-posttest quasi-experimental observational study was conducted in four hospitals, including 16 (medical/surgical/psychiatry) departments. The study consisted of four phases: Baseline assessment, intervention, three-month post-intervention assessment, and follow-up assessment after 15 months for sustainability. The intervention (role model in hand hygiene) consisted of four components: Leadership involvement as a role model for HH, posting HH messages with photos of role model leaders, a weekly selection of staff as HH role models, and conducting HH education and training from the focal point of each ward/department.

Results: There were 5796 observations recorded during the study for Moments 1 and 4 of HH. HCWs' overall compliance rate significantly increased from a baseline of 52.6% before the intervention to 74.1% after three months from the intervention, and 70.0% on follow-up after more than one year (p < 0.001). All the hospitals included, regardless of their baseline compliance, had a significant improvement in HH compliance post-intervention and were able to sustain compliance (> 60%) after 15 months from the start of the intervention. The likelihood of improvement in HH compliance with the intervention remained low for the moment before patient contact (AOR, 0.34; 95% CI = 0.27-0.44) during the weekend (AOR, 0.44; 95% CI = 0.32-0.59) in the psychiatry wards (AOR, 0.22; 95% CI = 0.15-0.34) and by the non-medical and nursing professions (AOR, 0.99; 95% CI = 0.61-1.66).

Conclusions: Implementation of a role model as a behavioral intervention, in addition to the WHO's multimodal strategy, successfully improved and sustained HCWs' HH compliance rates. Understanding healthcare culture in the context of the driving factors of behavioral changes and regular follow-ups are essential to sustain adherence to safe HH practices.
