Joint crisis plans for people with psychosis: economic evaluation of a randomised controlled trial.
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 7264 pounds sterling (10,616 euros, 13,560 dollars) for each participant with a joint crisis plan and 8359 pounds sterling (12,217 euros, 15,609 dollars) for each participant with standardised service information (mean difference 1095 pounds sterling; 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 in reducing the proportion of patients admitted to hospital. CONCLUSION: Joint crisis plans produced a non-significant decrease in admissions and 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.
Ethnic differences in mental health service use among patients with psychotic disorders.
BACKGROUND: There are concerns that ethnic minority patients are over-represented in inpatient mental health settings, but under-utilise community services. This study aims to compare the use of community mental health services between African-Caribbean and White patients with psychosis, before and after the introduction of new community services, and to investigate their impact on inpatient treatment. METHODS: The sample was drawn from epidemiologically representative patients with psychotic disorders living in two catchment areas in South London, one of which was developing intensive community treatments. Service utilisation was measured at baseline and at 2-year follow-up using the Client Service Receipt Interview (CSRI). The mean number of contacts with specific services was compared between the two groups over time. RESULTS: A total of 92 White and 48 African-Caribbean patients were compared. The latter were more likely to be younger (P = 0.004), have shorter illness duration (P < 0.001), and had more detentions under the Mental Health Act (P = 0.003). No significant differences were seen in use of community services over time. However, intensive treatment led to a significant reduction in hospital days for African Caribbean patients compared to White patients in the intensive sector and all patients in the standard sector. CONCLUSIONS: Intensive community treatments reduced inpatient days in African Caribbean patients. Further effort is needed to improve the cultural sensitivity of community mental health services.
Do community treatment orders for mental illness reduce readmission to hospital? An epidemiological study.
BACKGROUND: It has been suggested that community treatment orders (CTOs) will prevent readmission to hospital, but controlled studies have been inconclusive. We aimed to test the hypothesis that hospital discharges made subject to CTOs are associated with a reduced risk of readmission. The use of such a measure is likely to change after its introduction as clinicians acquire familiarity with it, and we also tested the hypothesis that the characteristics of patients subject to CTOs changed over time in the first decade of their use in Victoria, Australia. METHOD: A database from Victoria, Australia (total population 4.8 million) was used. Cox proportional hazard models compared the hazard ratios of readmission to hospital before the end of the study period (1992-2000) for 16,216 discharges subject to a CTO and 112,211 not subject to a CTO. RESULTS: Community treatment orders used on discharge from a first admission to hospital were associated with a higher risk of readmission, but CTOs following subsequent admissions were associated with lower readmission risk. The risk also declined over the study period. CONCLUSIONS: The effect of using a CTO depends on the patient's history. At a population level their introduction may not reduce readmission to hospital. Their impact may change over time. DECLARATION OF INTEREST: None.
Fusion of mental health and incapacity legislation.
The enactment of a single legislative scheme governing nonconsensual treatment of both 'physical' and 'mental' illnesses, based on incapacity principles, has been mooted in recent law reform debates in the UK. We propose a framework for such legislation and consider in more detail the provisions it should contain. The design of legislation that combines the strengths of both incapacity and civil commitment schemes can be readily imagined, based on the criteria for intervention in England and Wales found in the Mental Capacity Act 2005. Such legislation would reduce unjustified legal discrimination against mentally disordered persons and apply consistent ethical principles across medical law.
Commentary: toward resolving some dilemmas concerning psychiatric advance directives.
Dilemmas about when psychiatric advance directives (PADs) should be overridden are complicated by conflicting legal frameworks that may nonetheless operate concurrently-a legal scheme based on decision-making capacity (or competency) set against a legal scheme based on civil commitment, in which the latter may "trump" the former. A single statute in which the strengths of both schemes are "fused" may be possible. There is evidence that the promise of PADs in enhancing patients' control over their treatment can be achieved without legislation for PADs and where civil commitment is given legal precedence. An example is the "joint crisis plan" in which, through a negotiation facilitated by an independent third party, a joint agreement is reached between patient and service provider about what treatment should be given when, as a result of a relapse of mental illness, the patient loses the ability to make treatment decisions. This clinical instrument may significantly reduce later involuntary treatment.
Perceived coercion at admission to psychiatric hospital and engagement with follow-up--a cohort study.
BACKGROUND: Measures of perceived coercion at psychiatric hospital admission have been developed. We aimed to investigate predictors of perceived coercion in subjects admitted to psychiatric hospital in the UK, and to test the hypothesis that high perceived coercion at admission predicts poor engagement with community follow-up. METHOD: A cohort of consecutively admitted subjects were interviewed at admission and before discharge, and were followed prospectively for 10 months. Service use and compliance with care were rated from case notes and by clinicians. RESULTS: One hundred interviews were obtained from 118 consecutive admissions (85%). Compulsory admission was strongly associated with perceived coercion, but one-third of voluntary patients felt highly coerced, and two-thirds were not certain they were free to leave hospital. Greater age, less insight, and non-white ethnicity were associated with high perceived coercion. Perceived coercion did not predict engagement with follow-up. CONCLUSIONS: Services recognise provision of care in the least restrictive setting as a key objective. Perceived coercion should be regarded as an important outcome measure in service evaluation.
Reliability of mental capacity assessments in psychiatric in-patients.
BACKGROUND: Previous work on the reliability of mental capacity assessments in patients with psychiatric illness has been limited. AIMS: To describe the interrater reliability of two independent assessments of capacity to consent to treatment, as well as assessments made by a panel of clinicians based on the same interview. METHOD: Fifty-five patients were interviewed by two interviewers 1-7 days apart and a binary (yes/no) capacity judgement was made, guided by the MacArthur Competence Assessment Tool for Treatment (MacCAT-T). Four senior clinicians used transcripts of the interviews to judge capacity. RESULTS: There was excellent agreement between the two interviewers for capacity judgements made at separate interviews (kappa=0.82). A high level of agreement was seen between senior clinicians for capacity judgements of the same interview (mean kappa=0.84). CONCLUSIONS: In combination with a clinical interview, the MacCAT-T can be used to produce highly reliable judgements of capacity.
Prevalence and predictors of mental incapacity in psychiatric in-patients.
BACKGROUND: Little is known about the proportion of psychiatric in-patients who lack capacity to make treatment decisions, or the associations of lack of capacity. AIMS: To determine the prevalence of psychiatric in-patients who lack capacity to make decisions about current treatment and to identify demographic and clinical associations with lack of mental capacity. METHOD: Patients (n=112) were interviewed soon after admission to hospital and a binary judgement of capacity was made, guided by the MacArthur Competence Tool for Treatment. Demographic and clinical information was collected from an interview and case notes. RESULTS: Of the 112 participants, 49 (43.8%) lacked treatment-related decisional capacity. Mania and psychosis, poor insight, delusions and Black and minority ethnic group were associated with mental incapacity. Of the 49 patients lacking capacity, 30 (61%) were detained under the Mental Health Act 1983. Of the 63 with capacity, 6 (9.5%) were detained. CONCLUSIONS: Lack of treatment-related decisional capacity is a common but by no means inevitable correlate of admission to a psychiatric in-patient unit.
Effect of joint crisis plans on use of compulsory treatment in psychiatry: single blind randomised controlled trial.
OBJECTIVE: To investigate whether a form of advance agreement for people with severe mental illness can reduce the use of inpatient services and compulsory admission or treatment. DESIGN: Single blind randomised controlled trial, with randomisation of individual patients. The investigator was blind to allocation. SETTING: Eight community mental health teams in southern England. PARTICIPANTS: 160 people with an operational diagnosis of psychotic illness or non-psychotic bipolar disorder who had experienced a hospital admission within the previous two years. INTERVENTION: The joint crisis plan was formulated by the patient, care coordinator, psychiatrist, and project worker and contained contact information, details of mental and physical illnesses, treatments, indicators for relapse, and advance statements of preferences for care in the event of future relapse. MAIN OUTCOME MEASURES: Admission to hospital, bed days, and use of the Mental Health Act over 15 month follow up. RESULTS: Use of the Mental Health Act was significantly reduced for the intervention group, 13% (10/80) of whom experienced compulsory admission or treatment compared with 27% (21/80) of the control group (risk ratio 0.48, 95% confidence interval 0.24 to 0.95, P = 0.028). As a consequence, the mean number of days of detention (days spent as an inpatient while under a section of the Mental Health Act) for the whole intervention group was 14 compared with 31 for the control group (difference 16, 0 to 36, P = 0.04). For those admitted under a section of the Mental Health Act, the number of days of detention was similar in the two groups (means 114 and 117, difference 3, -61 to 67, P = 0.98). The intervention group had fewer admissions (risk ratio 0.69, 0.45 to 1.04, P = 0.07). There was no evidence for differences in bed days (total number of days spent as an inpatient) (means 32 and 36, difference 4, -18 to 26, P = 0.15 for the whole sample; means 107 and 83, difference -24, -72 to 24, P = 0.39 for those admitted). CONCLUSIONS: Use of joint crisis plans reduced compulsory admissions and treatment in patients with severe mental illness. The reduction in overall admission was less. This is the first structured clinical intervention that seems to reduce compulsory admission and treatment in mental health services.
Management of psychiatric in-patient violence: patient ethnicity and use of medication, restraint and seclusion.
BACKGROUND: Significant ethnic differences have been found previously on a forensic unit in the management of psychiatric patients after a violent incident. AIMS: To study the management of violent incidents on all general wards in a large psychiatric hospital in South London. The main question is whether there are differences in the management of Black patients involved in violent incidents compared with White patients and, if so, what are the factors leading to it? METHOD: All recorded violent incidents (1515 in total) on 14 general wards over three years (1994, 1996, 1998) were analysed using mixed logistic regression to estimate the odds ratio that the corresponding management decision (emergency medication, physical restraint, seclusion) was taken for Black patients compared with White patients after controlling for covariates and unobserved heterogeneity between subjects. RESULTS: Black patients were more likely than White patients to be given emergency medication and to be secluded after a violent incident, but not to be physically restrained. However, differences disappeared when the odds ratios were adjusted for other variables. CONCLUSIONS: Racial 'stereotyping' was unlikely to have played a major direct role in determining nurses' responses.
