Do care patterns change over time in a newly established mental health service? A report from the UK700 trial.

PURPOSE: Data on the process of mental health care is scant. Most studies focus on services at their inception when activity may be atypical and then usually present data only mean values for the reported variables over the whole study period. We aimed to test whether care delivery changes over time, and to describe any changes at the individual patient and team levels. METHODS: Process data on 272 patients in three new intensive case management (ICM) teams were collected over 2 years. Interventions were prospectively recorded using clinician-derived categories. Changes over time are described at both patient and team level. RESULTS: The number of contacts and the proportion of face-to-face activity were remarkably constant after the first month at the patient level. The proportion of 'psychiatric' interventions (main focus on medication or a specific 'mental health' intervention performed) increased greatly after the first 6 months. The care activity received by individual patients varied considerably. Overall, teams varied significantly in the extent to which their activity rates were sustained over time. CONCLUSIONS: New ICM teams deliver highly individualised care with more marked differences in treatment patterns between patients in the same team than mean differences between teams. The early 'engagement' period is marked by a greater focus on social care. There is evidence of differences in sustainability of the services by site.

The Nottingham study of neurotic disorder: predictors of 12 year costs.

OBJECTIVE: To examine the relationship between clinical, demographic and socio-economic characteristics and the long-term costs of a cohort of neurotic patients. METHOD: Analysis of the costs of a cohort of 210 people entered in the Nottingham study of neurotic disorders, a randomized controlled evaluation of five treatments for neurotic disorders. Service use data were collected at 5 and 12 years after study entry. Multiple regression analyses were conducted. RESULTS: The total cost per patient over the 12-year follow-up period was calculated to be $11,940 (SD $15,520) ( pound7450, SD pound9690). Higher costs were significantly associated with the presence of general neurotic syndrome, an initial diagnosis of dysthymia and a recurrent episode of illness. CONCLUSION: The total costs of care for a range of neurotic disorders are broadly comparable with other estimates of costs reported in the literature for similar populations. Those responsible for higher costs in the longer-term have comorbid anxiety, depressive and personality disorders.

Randomized controlled trial of brief cognitive behaviour therapy versus treatment as usual in recurrent deliberate self-harm: the POPMACT study.

BACKGROUND: We carried out a large randomized trial of a brief form of cognitive therapy, manual-assisted cognitive behaviour therapy (MACT) versus treatment as usual (TAU) for deliberate self-harm. METHOD: Patients presenting with recurrent deliberate self-harm in five centres were randomized to either MACT or (TAU) and followed up over 1 year. MACT patients received a booklet based on cognitive behaviour therapy (CBT) principles and were offered up to five plus two booster sessions of CBT from a therapist in the first 3 months of the study. Ratings of parasuicide risk, anxiety, depression, social functioning and global function, positive and negative thinking, and quality of life were measured at baseline and after 6 and 12 months. RESULTS: Four hundred and eighty patients were randomized. Sixty per cent of the MACT group had both the booklet and CBT sessions. There were seven suicides, five in the TAU group. The main outcome measure, the proportion of those repeating deliberate self-harm in the 12 months of the study, showed no significant difference between those treated with MACT (39%) and treatment as usual (46%) (OR 0.78, 95% CI 0.53 to 1.14, P=0.20). CONCLUSION: Brief cognitive behaviour therapy is of limited efficacy in reducing self-harm repetition, but the findings taken in conjunctin with the economic evaluation (Byford et al. 2003) indicate superiority of MACT over TAU in terms of cost and effectiveness combined.

Cost-effectiveness of brief cognitive behaviour therapy versus treatment as usual in recurrent deliberate self-harm: a decision-making approach.

BACKGROUND: Deliberate self-harm can be costly, in terms of treatment and subsequent suicide. Any intervention that reduces episodes of self-harm might therefore have a major impact on the costs incurred by service providers and the productivity losses due to illness or premature death. METHOD: Four hundred and eighty patients with a history of recurrent deliberate self-harm were randomized to manual-assisted cognitive behaviour therapy (MACT) or treatment as usual. Economic data were collected from patients at baseline, 6 and 12 months, and these data were complete for 397 patients. Incremental cost-effectiveness was explored using the primary outcome measure, proportion of patients having a repeat episode of deliberate self-harm, and quality of life. The uncertainty surrounding costs and effects was represented using cost-effectiveness acceptability curves. RESULTS: Differences in total cost per patient were statistically significant at 6 months in favour of MACT (pounds sterling -897, 95 % CI -1747 to -48, P=0.04), but these differences did not remain significant at 12 months (pounds sterling -838, 95% CI -2142 to 466, P=0.21). Nevertheless, exploration of the uncertainty surrounding these estimates suggests there is >90% probability that MACT is a more cost-effective strategy for reducing the recurrence of deliberate self-harm in this population over 1 year than treatment as usual. The results for quality of life were not conclusive. CONCLUSION: Cost-effectiveness acceptability curves demonstrate that, based on the evidence currently available, to reject MACT on traditional grounds of statistical significance and to continue funding current practice has <10% chance of being the correct decision in terms of cost-effectiveness.

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.

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.

Factors that influence the cost of caring for patients with severe psychotic illness: report from the UK 700 trial.

BACKGROUND: Many factors influence the type and quantity of services received by patients and, thus, the total cost of care. Knowledge of these factors can aid budgetary and service-planning decisions. AIMS: To investigate factors that influence the cost of caring for patients with severe psychotic illness. METHOD: Univariate and multivariate analyses were used to examine associations between baseline characteristics and subsequent 2-year total direct costs in 667 patients from the UK 700 case management trial. RESULTS: Significantly more money was spent on younger patients, those with longer duration of illness, those who had spent less time living independently and those who had spent longer in hospital for psychiatric reasons. CONCLUSIONS: Total costs of caring for patients with severe psychotic illness appear to be influenced to a large extent by age, duration of illness and past levels of dependence on statutory services. The strength of these relationships is greater than the impact of illness severity.

Randomised controlled trial of non-directive counselling, cognitive-behaviour therapy, and usual general practitioner care for patients with depression. II: cost effectiveness.

OBJECTIVE: To compare the cost effectiveness of general practitioner care and two general practice based psychological therapies for depressed patients. DESIGN: Prospective, controlled trial with randomised and patient preference allocation arms. SETTING: General practices in London and greater Manchester. PARTICIPANTS: 464 of 627 patients presenting with depression or mixed anxiety and depression were suitable for inclusion. INTERVENTIONS: Usual general practitioner care or up to 12 sessions of non-directive counselling or cognitive-behaviour therapy provided by therapists. MAIN OUTCOME MEASURES: Beck depression inventory scores, EuroQol measure of health related quality of life, direct treatment and non-treatment costs, and cost of lost production. RESULTS: 197 patients were randomly assigned to treatment, 137 chose their treatment, and 130 were randomised only between the two psychological therapies. At four months, both non-directive counselling and cognitive-behaviour therapy reduced depressive symptoms to a significantly greater extent than usual general practitioner care. There was no significant difference in outcome between treatments at 12 months. There were no significant differences in direct costs, production losses, or societal costs between the three treatments at either four or 12 months. Sensitivity analyses did not suggest that the results depended on particular assumptions in the statistical analysis. CONCLUSIONS: Within the constraints of available power, the data suggest that both brief psychological therapies may be significantly more cost effective than usual care in the short term, as benefit was gained with no significant difference in cost. There are no significant differences between treatments in either outcomes or costs at 12 months.

Randomised comparison of the effectiveness and costs of community and hospital based mental health services for children with behavioural disorders.

OBJECTIVE: To test the hypothesis that a community based intervention by secondary child and adolescent mental health services would be significantly more effective and less costly than a hospital based intervention. DESIGN: Open study with two randomised parallel groups. SETTING: Two health districts in the north of England. PARTICIPANTS: Parents of 3 to 10 year old children with behavioural disorder who had been referred to child and adolescent mental health services. INTERVENTION: Parental education groups. MAIN OUTCOME MEASURES: Parents' and teachers' reports of the child's behaviour, parental depression, parental criticism of the child, impact of the child's behaviour on the family. RESULTS: 141 subjects were randomised to community (n=72) or hospital (n=69) treatment. Primary outcome data were obtained on 115 (82%) cases a year later. Intention to treat analyses showed no significant differences between the community and hospital based groups on any of the outcome measures, or on costs. Parental depression was common and predicted the child's outcome. CONCLUSIONS: Location of child mental health services may be less important than the range of services that they provide, which should include effective treatment for parents' mental health problems.

Effects of case-load size on the process of care of patients with severe psychotic illness. Report from the UK700 trial.

BACKGROUND: Studies of intensive case management (ICM) for patients with psychotic illnesses have produced conflicting results in terms of outcome. Negative results have sometimes been attributed to a failure to deliver differing patterns of care. AIMS: To test whether the actual care delivered in a randomised clinical trial of ICM v. standard case management (the UK700 trial) differed significantly. METHOD: Data on 545 patients' care were collected over 2 years. All patient contacts and all other patient-centred interventions (e.g. telephone calls, carer contacts) of over 15 minutes were prospectively recorded. Rates and distributions of these interventions were compared. RESULTS: Contact frequency was more than doubled in the ICM group. There were proportionately more failed contacts and carer contacts but there was no difference in the average length of individual contacts or the proportion of contacts in the patients' homes. CONCLUSIONS: The failure to demonstrate outcome differences in the UK700 study is not due to a failure to vary the treatment process. UK standard care contains many of the characteristics of assertive outreach services and differences in outcome may require that greater attention be paid to delivering evidence-based interventions.

Randomised controlled trial of non-directive counselling, cognitive-behaviour therapy and usual general practitioner care in the management of depression as well as mixed anxiety and depression in primary care.

OBJECTIVES: The aim of this study was to determine both the clinical and cost-effectiveness of usual general practitioner (GP) care compared with two types of brief psychological therapy (non-directive counselling and cognitive-behaviour therapy) in the management of depression as well as mixed anxiety and depression in the primary care setting. DESIGN: The design was principally a pragmatic randomised controlled trial, but was accompanied by two additional allocation methods allowing patient preference: the option of a specific choice of treatment (preference allocation) and the option to be randomised between the psychological therapies only. Of the 464 patients allocated to the three treatments, 197 were randomised between the three treatments, 137 chose a specific treatment, and 130 were randomised between the psychological therapies only. The patients underwent follow-up assessments at 4 and 12 months. SETTING: The study was conducted in 24 general practices in Greater Manchester and London. SUBJECTS: A total of 464 eligible patients, aged 18 years and over, were referred by 73 GPs and allocated to one of the psychological therapies or usual GP care for depressive symptoms. INTERVENTIONS: The interventions consisted of brief psychological therapy (12 sessions maximum) or usual GP care. Non-directive counselling was provided by counsellors who were qualified for accreditation by the British Association for Counselling. Cognitive-behaviour therapy was provided by clinical psychologists who were qualified for accreditation by the British Association for Behavioural and Cognitive Psychotherapies. Usual GP care included discussions with patients and the prescription of medication, but GPs were asked to refrain from referring patients for psychological intervention for at least 4 months. Most therapy sessions took place on a weekly basis in the general practices. By the 12-month follow-up, GP care in some cases did include referral to mental healthcare specialists. MAIN OUTCOME MEASURES: The clinical outcomes included depressive symptoms, general psychiatric symptoms, social function and patient satisfaction. The economic outcomes included direct and indirect costs and quality of life. Assessments were carried out at baseline during face-to-face interviews as well as at 4 and 12 months in person or by post. RESULTS: At 4 months, both psychological therapies had reduced depressive symptoms to a significantly greater extent than usual GP care. Patients in the psychological therapy groups exhibited mean scores on the Beck Depression Inventory that were 4-5 points lower than the mean score of patients in the usual GP care group, a difference that was also clinically significant. These differences did not generalize to other measures of outcome. There was no significant difference in outcome between the two psychological therapies when they were compared directly using all 260 patients randomised to a psychological therapy by either randomised allocation method. At 12 months, the patients in all three groups had improved to the same extent. The lack of a significant difference between the treatment groups at this point resulted from greater improvement of the patients in the GP care group between the 4- and 12-month follow-ups. At 4 months, patients in both psychological therapy groups were more satisfied with their treatment than those in the usual GP care group. However, by 12 months, patients who had received non-directive counselling were more satisfied than those in either of the other two groups. There were few differences in the baseline characteristics of patients who were randomised or expressed a treatment preference, and no differences in outcome between these patients. Similar outcomes were found for patients who chose either psychological therapy. Again, there were no significant differences between the two groups at 4 or 12 months. Patients who chose counselling were more satisfied with treatment than those who chose c

Cost-effectiveness analysis of a home-based social work intervention for children and adolescents who have deliberately poisoned themselves. Results of a randomised controlled trial.

BACKGROUND: Little evidence exists regarding the effectiveness or cost-effectiveness of alternative treatment services in the field of child and adolescent psychiatry. AIMS: To assess the cost-effectiveness of a home-based social work intervention for young people who have deliberately poisoned themselves. METHOD: Children aged < or = 16 years, referred to child mental health teams with a diagnosis of deliberate self-poisoning were randomly allocated to either routine care (n = 77) or routine care plus the social work intervention (n = 85). Clinical and resource-use data were assessed over six months from the date of trial entry. RESULTS: No significant differences were found between the two groups in terms of the main outcome measures or costs. In a sub-group of children without major depression, suicidal ideation was significantly lower in the intervention group at the six-month follow-up (P = 0.01), with no significant differences in cost. CONCLUSIONS: A family-based social work intervention for children and adolescents who have deliberately poisoned themselves is as cost-effective as routine care alone.

Common errors and controversies in pharmacoeconomic analyses.

The need to demonstrate the cost effectiveness of healthcare interventions has led to a rapid increase in the use of economic tools within pharmaceutical evaluations. Pharmacoeconomics is employed at many stages of the evaluation process, helping to predict which products are likely to be economically viable at an early stage, and providing information to aid price and reimbursement negotiations as well as formulary and purchasing decisions in conjunction with phase III and IV clinical trials. The ability of economic evaluations to accurately determine the best use of society's scarce resources, however, is strongly influenced by the existence of areas of confusion, controversy and dispute which hinder the researcher at every step. A good economic evaluation requires a number of ingredients including: (i) relevant, good quality clinical data, raising issues of trial design, sample size and perspective; (ii) relevant costs and outcomes, measured, valued and discounted credibly and accurately; (iii) appropriate methods of data analysis (statistical, incremental and sensitivity); and, once the trial is over, (iv) presentation of the results in a way which maximises the generalisability of the results and, hence, the usefulness of the research. None of these areas are trouble-free but with understanding and openness, mistakes can be minimised.

Randomized trial of a home-based family intervention for children who have deliberately poisoned themselves.

OBJECTIVE: To establish whether an intervention given by child psychiatric social workers to the families of children and adolescents who had attempted suicide by taking an overdose reduced the patients' suicidal feelings and improved family functioning. METHOD: One hundred sixty-two patients, aged 16 or younger, who had deliberately poisoned themselves were randomly allocated to routine care (n = 77) or routine care plus the intervention (n = 85). The intervention consisted of an assessment session and four home visits by the social workers to conduct family problem-solving sessions. The control group received no visits. Both groups were assessed at the time of recruitment and 2 and 6 months later. The primary outcome measures were the Suicidal Ideation Questionnaire, the Hopelessness Scale, and the Family Assessment Device. RESULTS: There were no significant differences in the primary outcomes between the intervention and control groups at either of the outcome assessments. Parents in the intervention group were more satisfied with treatment (mean difference 1.4 [95% confidence interval 0.6 to 2.1]). A subgroup without major depression had much less suicidal ideation at both outcome assessments (analysis of covariance p < .01) compared with controls. CONCLUSIONS: The home-based family intervention resulted in reduced suicidal ideation only for patients without major depression.
