Evaluating Home Healthcare Workers' Safety Hazard Detection Ability Using Virtual Simulation.

Home healthcare workers (HHWs) are routinely exposed to occupational safety hazards when servicing patients in their homes that put them at risk for injury. These hazards can be broadly classified as "electric, fire and burn," "environmental," or "slip, trip, and lift" hazards. To better train HHWs regarding their potential exposure to these hazards, a home healthcare virtual simulation training system (HH-VSTS) was developed. The HH-VSTS contains three training modules, corresponding to the aforementioned hazard categories, and an assessment module. In each training module, the trainee must navigate the virtual space, via a mouse click, and identify items or conditions that represent hazards. Once an item has been clicked on, the HH-VSTS asks the user if the item or condition is a hazard. For items or conditions that are hazards, additional text boxes present material to the user as to why the item constitutes a hazard and potential remediation approaches. Thus, it is important that hazards be identified and clicked on for the trainee to receive the educational component of the training system. This article evaluated the ability of 49 HHWs to find hazards in each of the three categories. In all modules, participants found the most salient hazards (e.g., clutter on stairs, unattended candles, biohazard stains) but struggled to find some of the less salient hazards. Several less salient hazards included the pet food bowls in the path of travel, the frayed electrical cord, oxygen tube leaking into a mattress, hot water that was too hot, and elevated room temperatures. Overall, this analysis found that most of the hazards within the training modules could be found by naïve HH-VSTS users. These data suggest the need for including hints that guide users toward hazards with which they are less familiar.

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

OBJECTIVE: 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. MATERIALS AND METHODS: 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. RESULTS: 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. CONCLUSION: 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.
