Effectiveness of Disabled Patient Semi-sit to Stand Electric Transfer Lift “Easy Safety Transfer Model 3” to Caregiver’s Ergonomic (Phase 2)

Abstract

Background: This innovation was reviewed for risk incidence in 2018 according to the 2P Safety principles that occurred at the Sirindhorn National Medical Rehabilitation Institute and then introduced into the design thinking process, which focuses on human user-centered. Objective: To study the effectiveness of a disabled patient's semi-sit-to-stand electric transfer lift on the ergonomics of caregivers and further develop a prototype device that is easy to use and safe. Method: This was an experimental study using a disabled patient's semi-sit-to-stand electric transfer lift. Tested in a group of 30 pairs of disabled patients and caregivers (n = 30). Data was analyzed using descriptive statistics and a Wilcoxon signed-rank test, setting the statistical significance level at < .05. Results: When comparing the ergonomic risks of the two methods, it was found that the risk score in the disabled patient transfer step using a transfer device was different from transferring disabled patients using a caregiver (p-value < .001), significance level α = 0.05 and most of the disabled patient group felt comfortable to very comfortable (86.67%) and felt safe to very safe (93.33%). The group of caregivers were very satisfied with the use of the equipment in terms of the dimensions of the equipment, the ease of adjusting the parts of the equipment, the safety and security of the equipment, the durability, and the effectiveness of the equipment in meeting needs for a total of 5 items. Conclusion: The prototype innovation can greatly reduce the ergonomic risks of caregivers and meet the needs of users. This research does not yet have enough evidence to conclude that it can be commercially produced.
