The effect of alcohol consumption on cost of care in severe psychotic illness: a report from the UK700 study.

OBJECTIVE: Alcohol misuse in psychotic patients is common and leads to poor treatment outcome. This study examines the relationship between alcohol consumption and cost of care in patients with a severe psychotic illness. METHOD: Patient care was evaluated over 2 years for 708 patients. Patient reported alcohol consumption was evaluated at initial interview. The outcome measure was cost of care over 2 years. RESULTS: There was no difference in mean cost of care between non-drinkers, moderate and heavy drinkers. Increased alcohol consumption (measured as a continuous variable, adjusted for baseline characteristics) was associated with lower cost of care. CONCLUSION: Heavier alcohol consumers did not incur more treatment costs and may, indeed, cost less than other patients. This may reflect higher levels of drinking being associated with better overall functioning, poorer engagement with services or exclusion from services.

Difficulties in conducting a randomized controlled trial of health service interventions in intellectual disability: implications for evidence-based practice.

BACKGROUND: In an era of evidence-based medicine, practice is constantly monitored for quality in accordance with the needs of clinical governance (Oyebode et al. 1999). This is likely to lead to a dramatic change in the treatment of those with intellectual disability (ID), in which evidence for effective intervention is limited for much that happens in ordinary practice. As Fraser (2000, p. 10) has commented, the word that best explains "the transformation of learning disability practice in the past 30 years is 'enlightenment'." This is not enough to satisfy the demands of evidence, and Fraser exhorted us to embrace more research-based practice in a subject that has previously escaped randomized controlled trials (RCTs) of treatment because of ethical concerns over capacity and consent, which constitute a denial of opportunity which "is now at last regarded as disenfranchising". CONCLUSIONS: The present paper describes the difficulties encountered in setting up a RCT of a common intervention, i.e. assertive community treatment, and concludes that a fundamental change in attitudes to health service research in ID is needed if proper evaluation is to prosper.

Reducing violence in severe mental illness: randomised controlled trial of intensive case management compared with standard care.

OBJECTIVES: To establish whether intensive case management reduces violence in patients with psychosis in comparison with standard case management. DESIGN: Randomised controlled trial with two year follow up. SETTING: Four inner city community mental health services. PARTICIPANTS: 708 patients with established psychotic illness allocated at random to intervention (353) or control (355) group. INTERVENTION: Intensive case management (caseload 10-15 per case manager) for two years compared with standard case management (30-35 per case manager). MAIN OUTCOME MEASURE: Physical assault over two years measured by interviews with patients and case managers and examination of case notes. RESULTS: No significant reduction in violence was found in the intensive case management group compared with the control group (22.7% v 21.9%, P=0.86). CONCLUSIONS: Intensive case management does not reduce the prevalence of violence in psychotic patients in comparison with standard care.

Day hospital versus out-patient care for psychiatric disorders.

BACKGROUND: This review considers the use of day hospitals as an alternative to out-patient care. Three types of day hospital are covered by the review: 'day treatment programmes', 'day care centres' and 'transitional' day hospitals. Day treatment programmes offer more intense treatment for patients who have failed to respond to out-patient care (usually patients with affective or personality disorders). Day care centres offer structured support to patients with long-term severe mental disorders (mainly schizophrenia), who would otherwise be treated in the out-patient clinic. Transitional day hospitals offer time-limited care to patients who have just been discharged from in-patient care. OBJECTIVES: The review had three objectives. First, to assess the effectiveness of day treatment programmes versus out-patient care for people with treatment-refractory disorders. Second, to assess the effectiveness of day care centres versus out-patient care for people with severe long term disorders. Third, to assess the effectiveness of transitional day hospital care for people who had just been discharged from hospital. SEARCH STRATEGY: We searched the Cochrane Controlled Trials Register (Cochrane Library, issue 4, 2000), MEDLINE (January 1966 to December 2000), EMBASE (1980 to December 2000), CINAHL (1982 to December 2000), Psyc LIT (1966 to December 2000), and the reference lists of articles. Researchers were approached to identify unpublished studies. SELECTION CRITERIA: Randomised controlled trials comparing day hospital care (including day treatment programme, day care centre, and transitional day hospital) against out-patient care. Studies were ineligible if a majority of participants were under 18 or over 65, or who had a primary diagnosis of substance abuse or organic brain disorder. DATA COLLECTION AND ANALYSIS: Data were extracted independently by two reviewers and cross-checked. Relative risks and 95% confidence intervals (CI) were calculated for dichotomous data. Weighted or standardised means were calculated for continuous data. MAIN RESULTS: There was evidence from one trial suggesting that day treatment programmes were superior to continuing out-patient care in terms of improving psychiatric symptoms. There was no evidence that day treatment programmes were better or worse than out-patient care on any other clinical or social outcome variable, or on costs. There was no evidence that day care centres were better or worse than out-patient care on any clinical or social outcome variable. There were some inconclusive data on costs suggesting that day care centres might be more expensive than out-patient care. There was evidence from one trial suggesting that transitional day hospital care was superior to out-patient care in keeping patients engaged in treatment, however there was insufficient evidence to judge whether it was better or worse on any other clinical or social outcome variable, or on costs. REVIEWER'S CONCLUSIONS: There is only limited evidence to justify the provision of day treatment programmes and transitional day hospital care, and no evidence to support the provision of day care centres.

Prospective studies of cothymia (mixed anxiety-depression): how do they inform clinical practice?

We suggest that the diagnosis of mixed anxiety depression at syndromal level (i.e. both anxiety and depressive diagnoses present in the same person and given equal status) is valuable clinically and should be introduced into the formal classification of neurotic and mood disorders. Evidence is given from a systematic review that cothymia has a significantly worse outcome than either an anxiety or a depressive diagnosis alone (p < 0.0001). Long-term follow-up data in a 12-year outcome study of neurotic disorder reinforce this finding both with regard to social functioning and the clinical course of anxiety and depressive disorders; these were significantly worse (P < 0.001 and P < 0.02 respectively) in those with cothymia compared with single anxiety disorders. These outcome differences are much greater than those between anxiety and depressive disorders alone.

Costs and characteristics of heavy inpatient service users in outer London.

"Heavy users" is a new term often used to describe those who occupy a disproportionate number of psychiatric beds. In this study we identified the heaviest 10% (193) inpatient service users in one London borough over a 6 year period and compared these with a control group of 400 ordinary inpatient users. A weighting index was used to combine frequency of admission with duration. Heavy users were diagnostically and demographically similar to ordinary inpatient service users and only differed by their extensive use of services, about 3 times more than ordinary users in terms of health care costs, during the measured year. Their heavy use mainly depended on occupying hospital beds, and their use of outpatient, day patient and community services was relatively light.

Instrumental psychosis: the Good Soldier Svejk syndrome.

The possession of severe mental illness, mainly schizophrenia and affective psychosis, may be perceived in positive terms. We have identified a group of patients, most of them with a history of previous psychotic disorder, who present with deliberately created symptoms and behaviour, and who are defined as having instrumental psychosis. Because most such patients have had a psychotic disorder in the past the symptoms are very like those of a real psychosis. A parallel is drawn with the fictional anti-hero of the Czech nation, the Good Soldier Svejk, who demonstrated both real and instrumental psychosis. A rating scale, the 'pseudopsychosis inventory', was devised to identify the main components of this disorder and was applied in 15 consecutive patients presenting with putative psychotic disorders in whom assessment could be made by two raters within five days. The inter-rater reliability of the items of the scale was good (intra-class correlation coefficient 0.68). An epidemiological study with this scale in 45 patients with a putative psychotic disorder suggested the presence of instrumental psychosis in 2.

Intellectual functioning and outcome of patients with severe psychotic illness randomised to intensive case management. Report from the UK700 trial.

BACKGROUND: Little research has been carried out on the benefits of intensive case management (ICM) for people with borderline IQ and severe mental illness. AIMS: To compare outcome and costs of care of patients with severe psychotic illness with borderline IQ to patients of normal IQ and to assess whether ICM is more beneficial for the former than for the latter. METHOD: The study utilises data from the UK700 multi-centre randomised controlled trial of case management. The main outcome measure was the number of days spent in hospital for psychiatric reasons. Secondary outcomes were costs of care and clinical outcome. RESULTS: ICM was significantly more beneficial for borderline-IQ patients than those of normal IQ in terms of reductions in days spent in hospital, hospital admissions, total costs and needs and increased satisfaction. CONCLUSIONS: ICM appears to be a cost-effective strategy for a subgroup of patients with severe psychosis with cognitive deficits.

Community mental health team management in severe mental illness: a systematic review.

BACKGROUND: Community mental health teams are now generally recommended for the management of severe mental illness but a comparative evaluation of their effectiveness is lacking. AIMS: To assess the benefits of community mental health team management in severe mental illness. METHOD: A systematic review was conducted of community mental health team management compared with other standard approaches. RESULTS: Community mental health team management is associated with fewer deaths by suicide and in suspicious circumstances (odds ratio=0.32, 95% Cl 0.09-1.12), less dissatisfaction with care (odds ratio=0.34, 95% Cl 0.2-0.59) and fewer drop-outs (odds ratio=0.61, 95% Cl 0.45-0.83). Duration of in-patient psychiatric treatment is shorter with community team management and costs of care are less, but there are no gains in clinical symptomatology or social functioning. CONCLUSIONS: Community mental health team management is superior to standard care in promoting greater acceptance of treatment, and may also reduce hospital admission and avoid deaths by suicide. This model of care is effective and deserves encouragement.

A randomized controlled trial of community-oriented and hospital-oriented care for discharged psychiatric patients: influence of personality disorder on police contacts.

An important forensic psychiatric measure, contacts with police, was compared in a randomized, controlled trial of 155 patients with severe mental illness with a previous admission within the past two years. The patients, who also had their personality status addressed formally before randomization, were allocated to community multidisciplinary teams or to hospital-based care programs after discharge from in-patient care and were followed up for one year. A total of 138 patients (89%) had at least one post-baseline assessment and of these patients, 16 (12%) had at least one police contact in the year of the study, most of which were emergency assessments. The data showed significantly greater numbers of police contacts in patients with increasing severity of personality disturbance. Patients with such disturbance were six times more likely to have police contacts than those with no personality disorder. There were significantly more contacts in patients with borderline and antisocial (dissocial) personality disorder allocated to community-oriented care compared with hospital-oriented care. These findings have important implications for risk assessment in severe mental illness.

Systematic reviews of the effectiveness of day care for people with severe mental disorders: (1) acute day hospital versus admission; (2) vocational rehabilitation; (3) day hospital versus outpatient care.

UNLABELLED: ***ACUTE DAY HOSPITAL VERSUS ADMISSION FOR ACUTE PSYCHIATRIC DISORDERS*** BACKGROUND: Inpatient treatment is an expensive way of caring for people with acute psychiatric disorders. It has been proposed that many of those currently treated as inpatients could be cared for in acute psychiatric day hospitals. OBJECTIVE: The aim of this review was to assess the effectiveness and feasibility of day hospital versus inpatient care for people with acute psychiatric disorders. METHODS - STUDY SELECTION: Eligible studies were randomised controlled trials of day hospital versus inpatient care for people with acute psychiatric disorders. Studies were excluded if they were primarily concerned with elderly people, children, or patients with a diagnosis of organic brain disease or substance abuse. METHODS - DATA SOURCES: We searched the Cochrane Controlled Trials Register, MEDLINE, EMBASE, CINAHL, PsycLIT, and the reference lists of articles. Researchers were approached to identify unpublished studies. Trialists were asked to provide individual patient data. METHODS - DATA EXTRACTION: Data were extracted independently by two reviewers and cross-checked. METHODS - DATA SYNTHESIS: Relative risk (RR) and 95% confidence intervals (CIs) were calculated for dichotomous data. Weighted or standardised means were calculated for continuous data. Day hospital trials tend to present similar outcomes in slightly different formats, making it difficult to synthesise the data. Individual patient data were therefore sought so that outcomes could be re-analysed using a common format. RESULTS: Nine trials met the inclusion criteria (involving 1568 randomised patients and 2268 assessed for suitability of day hospital treatment). Individual patient data were obtained for four trials (involving 594 people). A sensitivity analysis of combined data suggested that day hospital treatment was feasible for at worst 23.2% (n = 2268; 95% CI, 21.2 to 25.2) and at best 37.5% (n = 1768; 95% CI, 35.2 to 39.8) of those currently admitted to inpatient care. Individual patient data from three trials showed no difference in the number of days in hospital (combining day hospital days and inpatient days) between day hospital patients and controls (n = 465; weighted mean difference (WMD) = -0.38 days/ month; 95% CI, -1.32 to 0.55). However, compared with controls, patients randomised to day hospital care spent significantly more days in day hospital care (n = 265; WMD = 2.34 days/month; 95% CI, 1.97 to 2.70) and significantly fewer days in inpatient care (n = 265; WMD = -2.75 days/month; 95% CI, -3.63 to -1.87). There was no difference between readmission rates for day hospital and control patients (n = 667; RR = 0.91; 95% CI, 0.72 to 1.15). Individual patient data from three trials showed a significant time-treatment interaction, indicating a more rapid improvement in mental state (n = 407; c2 = 9.66; p = 0.002), but not social functioning (n = 295; c2 = 0.006; p = 0.941) amongst day hospital patients. Four of five trials demonstrated that day hospital care was cheaper than inpatient care (with overall cost reductions ranging from 20.9% to 36.9%). CONCLUSIONS: Acute day hospitals are an attractive option in situations where demand for inpatient care is high and facilities exist that are suitable for conversion. They are a less attractive option when demand for inpatient care is low and where effective alternatives already exist. The interpretation of day hospital research would be enhanced if future trials made use of the common set of outcome measures used in this review. It is important to examine how acute day hospital care can be most effectively integrated into a modern community-based psychiatric service. ***VOCATIONAL REHABILITATION FOR PEOPLE WITH SEVERE MENTAL DISORDERS*** BACKGROUND: People who are disabled by severe mental disorders experience high rates of unemployment, but most want to work. Prevocational training (PVT) is the traditional approach to helping such people to return to work. PVT assumes that a period of preparation is required before those with a severe mental disorder can enter into competitive employment. Supported Employment (SEm) is a new approach that places clients in competitive employment without extended preparation. Both PVT and SEm are widely practised, but it is unclear which is the most effective. OBJECTIVES: The overall objective of this review was to assess the effectiveness of PVT and SEm relative to each other and to standard care (in hospital or the community) for people with severe mental disorders. In addition, the review examined the effectiveness of: (1) special types of PVT ("clubhouse" model) and SEm (individual placement and support model); and (2) modifications for enhancing PVT (e.g. payment or psychological interventions). METHODS - STUDY SELECTION: Eligible studies were randomised controlled trials (RCTs) examining the effectiveness of vocational rehabilitation approaches (PVT and SEm or modifications) for people of working age and suffering from a severe mental disorder. METHODS - DATA SOURCES: Relevant trials were identified from searches of the Cochrane Schizophrenia Group's specialised register, MEDLINE, EMBASE, CINAHL and PsycLIT, and the reference lists of all identified studies and review articles. Researchers who were active in the field were approached in order to identify unpublished studies. METHODS - DATA EXTRACTION: All data were extracted independently by two reviewers and cross-checked. Continuous data were excluded if they were collected by using an unpublished scale or were based on a subset of items from a scale. METHODS - DATA SYNTHESIS: For all comparisons, the primary outcome was the number of clients who were in competitive employment at various time points. Secondary outcomes were: other employment outcomes, clinical outcome and costs. The relative risk (RR) and number-needed-to-treat (NNT) were calculated for the relevant categorical outcomes. Continuous data were either presented as in the original trial reports or, where possible, combined across trials as a standardised mean difference score. RESULTS: Eighteen RCTs of reasonable quality were identified: PVT versus hospital controls, three RCTs, n = 172; PVT versus community controls, five RCTs, n = 1204; modified PVT, four RCTs, n = 423; SEm versus community controls, one RCT, n = 256; and SEm versus PVT, five RCTs, n = 491). The main finding was that, on the primary outcome (number in competitive employment), SEm was significantly more effective than PVT at all time points (e.g. at 12 months, SEm 34% employed, PVT 12% employed; RR of not being in competitive employment = 0.76, 95% confidence interval 0.69 to 0.84, NNT = 4.5). Clients in SEm also earned more and worked more hours per month than those in PVT. CONCLUSIONS: The main finding was that SEm was more effective than PVT for patients suffering from a severe mental disorder who wanted to work. There was no evidence that PVT was more effective than standard community care or hospital care. The implication of these findings is that people suffering from mental disorders who want to work should be offered the option of SEm. Commissioning agencies would be justified in encouraging vocational rehabilitation (VR) providers to develop more SEm schemes. From a research perspective, the cost-effectiveness of SEm should be examined in larger multicentre trials, both within and outside the USA. There is a case for countries outside the USA to survey their existing VR services to determine the extent to which the most effective interventions are being offered. ***DAY HOSPITAL VERSUS OUTPATIENT CARE FOR PATIENTS WITH PSYCHIATRIC DISORDERS*** BACKGROUND: This review considers the use of day hospitals as an alternative to outpatient care. Two typesof day hospital provision are covered: "day treatment programmes" and "day care centres". Day treatment programmes are day hospitals that are used to enhance the treatment of patients with anxiety or depressive disorders who have failed to respond to outpatient care. Day care centres are day hospitals that offer structured support to patients with long-term severe mental disorders who would otherwise be treated in an outpatient clinic. OBJECTIVES: There were two objectives: first, to assess the effectiveness of day treatment programmes versus outpatient care for people with non-psychotic disorders; and, secondly, to assess the effectiveness of day care centres versus outpatient care for people with severe long-term disorders. METHODS - STUDY SELECTION: Eligible studies were randomised controlled trials comparing day hospital care (either a day treatment programme or a day care centre) with outpatient care. Studies were ineligible if they were largely restricted to patients who were aged under 18 or over 65 years or who had a primary diagnosis of substance abuse or organic brain disorder. METHODS - DATA SOURCES: Relevant trials were identified from searches of the Cochrane Controlled Trials Register, MEDLINE, EMBASE, CINAHL, PsycLIT, and the reference lists of all identified studies and review articles. Researchers were approached to identify unpublished studies. Trialists were asked to provide individual patient data. METHODS - DATA EXTRACTION: All data were extracted independently by two reviewers and cross-checked. METHODS - DATA SYNTHESIS: Relative risks and 95% confidence intervals were calculated for dichotomous data. Standardised mean differences were calculated for continuous data. RESULTS: There was evidence from two of the five trials identified suggesting that day treatment programmes were superior to continuing outpatient care in terms of improving psychiatric symptoms. There was no evidence to suggest that day treatment programmes were better or worse than outpatient care on any other clinical or social outcome variable or on costs. (ABSTRACT TRUNCATED)

Community mental health teams (CMHTs) for people with severe mental illnesses and disordered personality.

BACKGROUND: Closure of asylums and institutions for the mentally ill, coupled with government policies focusing on reducing the number of hospital beds for people with severe mental illness in favour of providing care in a variety of non-hospital settings underpins the rationale behind care in the community. A major thrust towards community care has been the development of community mental health teams (CMHT). OBJECTIVES: To evaluate the effects of community mental health team (CMHT) treatment for anyone with serious mental illness. SEARCH STRATEGY: Electronic searches of Biological Abstracts (1982-1997), the Cochrane Library (1998, Issue 2), EMBASE (1980-1997), MEDLINE (1966-1997), PsycLIT (1974-1997) and SCISEARCH (1997) were undertaken. The Journal of Personality Disorders was hand searched, and contact was made with colleagues at ENMESH, ISSPD and in forensic psychiatry. SELECTION CRITERIA: All randomised or quasi-randomised controlled trials of CMHT management versus non-team standard care. DATA COLLECTION AND ANALYSIS: The selection of trials, assessment of quality and data extraction was undertaken independently and in parallel by two reviewers. Where possible the data were entered into RevMan and an intention-to-treat analysis undertaken. Tests of heterogeneity were undertaken. MAIN RESULTS: CMHT management may be associated with fewer deaths by suicide and in suspicious circumstances (OR 0.32 CI 0.09-1.12). It causes less people to be dissatisfied with their care (OR 0.34 CI 0.2-0.59) and to leave the studies early (OR 0.61 CI 0.45-0.83). No clear difference was found in admission rates, overall clinical outcomes and duration of in-patient hospital treatment, although this was partly a consequence of poorly presented data. REVIEWER'S CONCLUSIONS: Community mental health team management is not inferior to non-team standard care in any important respects and is superior in promoting greater acceptance of treatment. It may also be superior in reducing hospital admission and avoiding death by suicide.

The geographical mobility of severely mentally ill residents in London.

BACKGROUND: There is currently great concern over the demands on psychiatric services in metropolitan areas in most developed countries, and this is exemplified in capital cities. These greater demands were not anticipated by those planning psychiatric services and the consequences have led to insufficient beds in many areas. We investigated the geographical mobility (the number of changes of address in the past 2 years) of patients presenting to services in greater London, to determine whether this might be a possible factor in the increased demand. METHOD: The geographical mobility of the severely mentally ill was determined by taking a random sample of all psychiatric admissions to hospitals serving residents in the London area over the calendar year of 1994 (n = 156) and an equivalent sample of patients in an established community mental health team (n = 74) in one area (Paddington). The extent of geographical movement was determined for the 2 years prior to interview. RESULTS: Greater geographical movement in the in-patient group was found for those living in inner London compared with outer London and for patients admitted to hospitals outside their catchment area. Twenty-eight percent of the in-patient sample had changed address in the year before admission (including 13% more than once) and 39% had changed address in the 2 years prior to admission. By contrast, the patients seen by the community psychiatric team were less than half as likely to have changed address over the previous year as the in-patients, and none of the community team's patients had changed address more than once over the previous year. The geographically mobile patients had significantly longer periods in hospital than geographically stable patients. CONCLUSION: Geographical mobility of psychiatric patients in London is high and is particularly marked for those presenting for in-patient treatment. These findings suggest that greater mobility could be one of the most important reasons for the higher than expected demands on psychiatric services and the difficulties in maintaining contact with patients in London in general and inner London in particular. More attention should be paid to geographical mobility as a predictor of psychiatric service use, and it is recommended that it is recorded regularly in information systems.
