Effects of intervention program for systematic use of transfer equipment on care workers' low back pain in elderly care facilities.
The purpose of this study was to investigate the effects of an intervention program to prevent care workers' low back pain by the systematic use of transfer equipment at elderly care facilities.



Questionnaire surveys were administered to administrators and care workers before (baseline), 1 year after, and 2.5 year after starting the program at two elderly care facilities. Care workers at the intervention facility were requested to ensure the use of a transfer's hoist, sliding board, and sliding sheet when assisting in the transfer of residents who were judged as appropriate to use the equipment (27.5% of residents living the intervention facility). Care workers at the control facility received no instructions on the use of transfer equipment.



The average response rate of administrators and care workers was 100% and 90.3%, respectively. The number of care workers who responded during all three survey periods was 29 at the intervention facility and 23 at the control facility, and they were subjected to the current analysis. At baseline, transfer equipment was already introduced in both facilities, but it was found that the care workers did not regularly use it for assisting transfer. At 2.5-year follow-up, 31.0% of the intervention group and 4.3% of the control group always used the transfer's hoist. Similarly, 27.6% of the intervention group and 4.3% of the control group always used the sliding board and sliding sheet. Further, 60%-70% of the care workers at both facilities reported of having low back pain, but no statistically significant difference was found between the facilities or over the measurement periods. Among the intervention group, however, the care workers who reported an active use of the transfer's hoist, sliding board, and sliding sheet showed an improvement in low back pain. In the control group, no significant association was found between the active use of transfer equipment and low back pain.



These results indicated that the prevention of care workers' low back pain requires the introduction of transfer equipment in facilities and its regular use under the implementation program. If the number of residents requiring transfer equipment increases, its systematic use is expected to improve low back pain in care workers. This improvement can translate into safer and healthier workplaces for elderly care.
