“…Active treatment to assist recovery from physical illness in old age was advocated by Marjory Warren, a geriatrician, in 1943, 23 and for mental illness by Felix Post, a psychiatrist, in 1944. 24 Despite that, specialist rehabilitation facilities, for example to enable discharge home for elderly people who have required inpatient treatment for physical conditions co-existing with psychiatric illness, remain a rarity. 25 In addition, failure to provide rehabilitation and often relatively low-cost, community management for long-term multi-factorial disability has humane and economic implications, since it may result in unnecessary long-stay institutional placement or high-cost crisis re-admissions to acute hospitals.…”
