Accidental deaths occurring in bed: review of cases and proposal of preventive strategies.

The bed is thought to be a safe place, but posses a number of risks that can cause deaths. To identify the causes of accidental death in bed and propose strategies for the prevention of further accidents, we surveyed and analyzed the literature on accidental deaths in bed from Japan and abroad, as well as legal cases related to accidental death in bed in Japan. A search of the medical literature in Japan (1983-2007), abroad (1976-2007), and Japan's legal cases (1989-2007) located 39 cases. The vast majority of accidental deaths in bed occur among infants and elderly individuals with neurologic disorders. The main causes of death within these two groups are head injuries caused by falls from a bed and asphyxia caused by pressure to the neck when wedged against a bed rail. It is necessary to focus on prevention of falls from bed and prevention of asphyxia caused by bed rails in the case of infants and elderly individuals with neurologic disorders. Infants should be placed to sleep in beds designed for their ages and placed on their back. Elderly individuals need to sleep in beds with properly fitting bed rails to reduce wedging.
