The goal of the grant process was to develop a device which may be useful in decreasing the incidence of occupational injury in the American health care industry. Specifically, the goal was to develop a device which could accomplish transfer and transport of hospital and other patients without manual lifting by nursing personnel. Inherent in this goal was to develop a device which would be safe for patients and staff members, easily and conveniently used and stored, and cost effective. The developed device was evaluated to identify product risks prior to design of the production model. The efficacy of various assistive devices, along with the developed device (SCAT) was evaluated in reducing neck/shoulder/back stress to nursing students while carrying out the patient handling tasks of: transfer from the bed, transfer from floor to bed, and transporting a patient from one location to another, along with the patient's reaction in relation to feelings of comfort and security while being transferred and transported. The assistive devices used in transferring from the bed were a draw sheet, two friction reducing assistive devices, and the SCAT; a modern, battery operated mechanical lift and SCAT were used for transferring from the floor to the bed; and a stretcher and SCAT were used for transporting. In comparison with other assistive devices, the SCAT was found to be an effective device to use for transferring patients from the bed, lifting them from the floor, and transporting them from one location to another. For many of the transfers, it does take more time, but time can be offset by the lesser amount of exertion perceived to various body parts by the individuals doing the transfers, the greater feelings of comfort and security expressed by the patients, and the fewer number of people needed to carry out these transfers. The evaluation of the SCAT are presented in this report.
