Randomised controlled trial of two models of care for discharged psychiatric patients.

OBJECTIVE To compare the clinical outcome and costs of care of psychiatric patients allocated to community multidisciplinary teams or to hospital based care programmes after discharge from inpatient care. DESIGN Randomised controlled trial. SETTING Inner London (Paddington and North Kensington) and outer London (Brent) psychiatric services. SUBJECTS 155 patients with severe mental illness with a previous admission within the past 2 years. MAIN OUTCOME MEASURES Ratings of clinical psychopathology, depression, anxiety, and social functioning; comprehensive costs of health care. RESULTS Clinical outcomes were available for 133 patients and cost data for 144 patients after 1 year. The clinical outcomes of the two models of care were essentially similar, but admission to hospital was more likely in the hospital based care group and the costs of health care were 14% greater per patient than in the community group. This difference, however, was dwarfed by a twofold difference in the costs of care in the outer London services compared with those in inner London. This was explained largely by greater inpatient care for outer London patients (58 median bed days v 18 for inner London patients), more of which was provided by extracontractual referrals to other psychiatric hospitals as Brent had only 0.28/1000 beds available for acute adult patients compared with 0.82/1000 in Paddington and North Kensington over the period of the study. CONCLUSION Aftercare by community teams for psychiatric patients with severe mental illness has a similar outcome to hospital based aftercare but with fewer admissions to hospital. When psychiatric bed requirements are insufficient for a population, however, neither form of aftercare is effective as greater use of hospital beds elsewhere swamps any advantage of community care programmes, with disintegration and discontinuity of psychiatric services leading to escalating costs.
