SynopsisRecent follow-up studies of depression in old age have highlighted the high relapse rate in older patients compared with younger patients. The consequences for the provision of acute psychiatric beds for elderly patients has been investigated by comparing the usage of beds by younger and older patients with depression over a 4-year period. Overall, elderly depressed patients consumed one and a half times as many bed days as younger depressed patients and a quarter of all acute bed days available in the hospital were used by elderly depressed patients.
