To relieve the stress of caregivers, it is critical to identify and classify the burden factors in the elderly patients. In order to determine the factors that exhaust caregivers, a cross sectional survey was done. The study employed a self-recording questionnaire form which included the Pines' burnout scale and the level of patient's basic activities of daily living (BADL). Seventy-three caregivers filled in the questionnaire. They reported the difficulty of care for an elderly patient in the home, and the degree of the difficulty correlated well with the burnout score (r = -0.517; p < 0.001). The caregivers' burnout score did not correlate so well with the level of their patient's BADL (r = -307; p = 0.014). Among the factors in BADL, aid for toilet use, feeding, sitting, and transferring raised the burnout scale. On the other hand, assistance for bathing and dressing did not correlate with the burnout score. On multiple regression analysis using the background factors for the burnout score as explanatory variables, aid for feeding and sitting were significant independent contributing factors. Since it became clear that the caregivers in the home were almost burnt out owing to the aid they need to give for the elderly person's BADL, attempts should be done to reduce their burden as soon as possible.
