[Association between the change in the job facilitating and inhibiting factors of care staff due to the employment of older assistant workers and the emotional exhaustion among care staff].

Abstract

Objectives　The mental health condition of care staff in Japan is becoming problematic. Older assistant workers are currently being employed to assist care staff with their jobs and alleviate their job burden. This employment of older assistant workers is drawing attention; however, their influence on the job facilitating and inhibiting factors of care staff and the association with the care staff's emotional exhaustion remains unclear. In this study, we aim to examine how the employment of older care assistant workers relates to the job-facilitating and job-inhibiting factors of care staff and explore that association with the care staff's emotional exhaustion.Methods　Data from a mail survey of geriatric health services facilities with older assistant workers were analyzed. Among the answers obtained from the care staff, answers from 5,185 who reported working in facilities that employ older assistant workers (over the age of 60) were analyzed. The Emotional Exhaustion subscale of the Japanese Version of the Burnout Questionnaire was used as the dependent variable. The change in job-facilitating and job-inhibiting factors of care staff due to the employment of older assistant workers (improve, maintain/exacerbate) was explored for nine contents.Results　Care staff reported a decrease in the total volume of the task (63.6%), less stress during daily tasks (39.8%), and more concentration on the tasks that require expert care knowledge (38.0%). The results of multiple regression analysis showed that the emotional exhaustion score of care staff was low when the total volume of tasks decreased (β=－0.383, 95%CI=－0.719, －0.047), when less stress was perceived during daily tasks (β=－0.432, 95%CI=－0.796, －0.068), when concentration on tasks that required expert care knowledge increased (β=－0.574, 95%CI=－0.937, －0.210), and when human relationships among staff improved (β=－0.871, 95%CI=－1.263, －0.480). Conversely, an increase in tasks requiring work with regional personnel and organizations (β=0.800, 95%CI=0.162, 1.437) was associated with a high emotional exhaustion score.Conclusion　The employment of older care workers was related to the job-facilitating or job-inhibiting factors of care staff, and the change in these factors was associated with lower emotional exhaustion. The employment of older personnel may lower the risk of burnout among care staff.
