Factors promoting resident deaths at aged care facilities in Japan: a review

Due to an increasingly ageing population, the Japanese government has promoted elderly deaths in aged care facilities. However, existing facilities were not designed to provide resident end-of-life care and the proportion of aged care facility deaths is currently less than 10%. Consequently, the present review evaluated the factors that promote aged care facility resident deaths in Japan from individual- and facility-level perspectives to exploring factors associated with increased resident deaths. To achieve this, MEDLINE, CINAHL, Web of Science and Ichushi databases were searched on 23 January 2016. Influential factors were reviewed for two healthcare services (insourcing and outsourcing facilities) as well as external healthcare agencies operating outside facilities. Of the original 2324 studies retrieved, 42 were included in analysis. Of these studies, five focused on insourcing, two on outsourcing, seven on external agencies and observed facility/agency-level factors. The other 28 studies identified individual-level factors related to death in aged care facilities. The present review found that at both facility and individual levels, in-facility resident deaths were associated with healthcare service provision, confirmation of resident/family end-of-life care preference and staff education. Additionally, while outsourcing facilities did not require employment of physicians/nursing staff to accommodate resident death, these facilities required visits by physicians and nursing staff from external healthcare agencies as well as residents' healthcare input. This review also found few studies examining outsourcing facilities. The number of healthcare outsourcing facilities is rapidly increasing as a result of the Japanese government's new tax incentives. Consequently, there may be an increase in elderly deaths in outsourcing healthcare facilities. Accordingly, it is necessary to identify the factors associated with residents' deaths at outsourcing facilities.
