We compared bedridden elderly people living at home to others who were hospital inpatients. Questionnaires regarding medical status and care were returned by 85 of 116 people caring for a bedridden elderly person at home in Obu city, Aichi prefecture and by 62 of 64 nurses and family members caring for bedridden inpatients at Chubu National hospital. All subjects were at least 65 years old. The median age in both groups was 81 years, neither age distribution nor female sex predominance differed between both groups. The percentage of subjects with only one underlying disease was 62.5% among those living at home and 64.4% among inpatients. In both groups the most common disease was cerebrovascular disease (42.5% among those at home and 39.0% among inpatients), followed by dementia (31.3%), infirmity of old age (17.5%) and bone fracture (13.8%) among those at home, and by bone fracture (27.1%), dementia (20.3%) and infirmity of old age (16.9%) among inpatients. The median durations of bedridden status were 2 years and 3 months among those at home and 3 months among inpatients. The proportion of subjects bedridden for less than 6 months was greater among inpatients (p < 0.0001). The percentage who needed medical treatment was 60.0% among those at home and 67.7% among inpatients. The most common conditions for which drugs were taken were hypertension, dementia, chronic cerebrovascular dysfunction, and osteoporosis. Among inpatients, 54.8% were ambulatory before admission, 24.2% were almost completely bedridden, and 17.7% were completely bedridden. The most common cause rending the patients bedridden was infection (usually pneumonia). The degree of disability did not differ between groups. Decubitus ulcers were present in 25.9% of those at home and 17.7% of inpatients.
