[Factors influencing the death of the elderly at home in an institution specializing home medical care--analysis of survey of the bereaved family].

AIM: To determine factors influencing on the death of the elderly at home in an institution specializing in-home medical care (home death rate: about 80%). METHODS: This study was an anonymous mailed survey of bereaved families of patients (the caregivers) who died using the home medical care setting provided by an institution specializing in home medical care in Japan. We analyzed the relationship of demographics of the patients and the caregivers with such factors as the anxiety of the caregiver and eventual death at home, and that of such factors as perceived quality of home medical care by the caregiver, and satisfaction with home medical care, satisfaction with death bed nursing, regret for death bed nursing. RESULTS: The most significant determinant factor associated with home death was that both patients and caregivers preferred death at home (OR=19.42). Determination coefficients (R(2)) in the multiple linear regression analysis of caregiver's satisfaction with home medical care, satisfaction with death bed nursing and regret for death bed nursing were as high as 0.68, 0.55 and 0.62, respectively. Significant influential factors were: peaceful death, psychological consistency of the caregiver, a good relationship with one's physician and fulfillment of the care service system. CONCLUSIONS: Important components of home medical care and death bed nursing for the realization of death of the elderly at home are 1) peaceful death, 2) psychological consistency of caregivers, 3) a good relationship with one's physician, 4) fulfillment of the care service system.
