Objective To investigate the cost effectiveness of joint crisis plans.. a form of advance agreement for people with severe mental illness. Design Single blind randomised controlled trial. Setting Eight community mental health teams in southern England. Participants 160 people with a diagnosis of psychotic illness or non-psychotic bipolar disorder who had been admitted to hospital at least once within the previous two years. Intervention joint crisis plan formulated by the patient, care coordinator, psychiatrist, and project worker containing contact information, details of illnesses, treatments, relapse indicators, and advance statements of preferences for care for future relapses. Control group was standardised service information. Main outcome measures Admission to hospital; service use over 15 months. Results Use of a joint crisis plan was associated with less service use and lower costs on average than in the standardised service information group, but differences were not significant. Total costs during follow-up were,0264 (E10 616, $13 560) for each participant with a joint crisis plan and;8359 pound (E12 217. $15 609) for each participant with standardised service information (mean difference 1095; pound 95% confidence interval - 2814 to 5004). Cost effectiveness acceptability curves, used to explore uncertainty in estimates of costs and effects, suggest there is a greater than 78% probability that joint crisis plans are more cost effective than standardised service information ill reducing the proportion of patients admitted to hospital. Conclusion joint crisis plans produced a non-significant decrease in admissions mid total costs. Though the cost estimates had wide confidence intervals, the associated uncertainty suggests there is a relatively high probability, of the plans being more cost effective than standardised service information for people with psychotic disorders
