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

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.

The role of supporting services in driving SARS-CoV-2 transmission within healthcare settings: A multicenter seroprevalence study.

Objective: To determine the seroprevalence of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in healthcare workers (HCWs) based on risk of exposure to COVID-19 patients.

Method: This was a SARS-CoV-2 seroprevalence cross-sectional study in risk-stratified HCWs randomly selected from three main district hospitals in Oman.

Results: 1078 HCWs were included, with an overall SARS-CoV-2 seroprevalence of 21%.
