Exploring the usability and perceived benefits and barriers of portable lift assist devices among paramedic workers.

Patient lifting can expose health care workers to musculoskeletal disorder (MSD) risk factors. Portable lift assist devices may reduce exposure during lifting, however limited evidence on user feedback and efficacy is available to inform purchase decisions. Therefore, we tested the efficacy of two portable lift assist devices relative to a manual lift when lifting an individual from the floor. Participants lifted an actor from the floor using a manual technique and by using two lift assist devices, either an inflatable bladder or a mechanical device. Ratings of perceived exertion demonstrated that the lift assist devices decreased or maintained perceived exertion relative to the manual lift. Semi-structured interviews provided context where perceived benefits of the devices (i.e., decreased exertion and MSD risk) outweighed barriers (i.e., added time to call). The results of this study can inform stakeholders making decisions about lift assist devices purchases.
