Efficacy and Usability of a Virtual Simulation Training System for Health and Safety Hazards Encountered by Healthcare Workers.

Abstract

This study evaluated the efficacy, usability, usefulness, and desirability (UUD) of a Home Healthcare Interactive Virtual Simulation Training System (HH-VSTS) designed to train home healthcare workers (HHWs) and healthcare students to identify and respond to health and safety hazards in client homes. Participants were randomly assigned to either the HH-VSTS training group or to the paper-based training group. The HH-VSTS group completed three HH-VSTS Training Modules on a laptop/desktop computer. The training modules addressed hazard identification, hazard rationale, and hazard response to electric/fire/burn, slip/trip/lift, and environmental hazards. The paper-based training group reviewed identical information in a written hard-copy format. Both groups completed an HH-VSTS Assessment module. Participants completed demographic/background and UUD questionnaires, and in-system metrics measured their performance on hazard identification, rationale, and response. Participants (n = 74) were HHWs and students in health profession programs. There were no significant differences in participants' ability to correctly identify hazards, rationale, or how to address them. Participants identified over 90% of hazards, although fewer participants were able to correctly identify what makes an item a hazard or how to manage it. For those in the HH-VSTS group, over 83% found the HH-VSTS easy to use, over 94% agreed the HH-VSTS was useful, and over 80% liked it. The HH-VSTS provided and engaging, efficacious training that was as effective as a typical paper-based training. In addition, the HH-VSTS is usable by a variety of end users, regardless of computer or gaming experience.
