Objective To determine the most effective way of helping people with severe mental illness to obtain competitive employment-that is, a job paid at the market rate, and for which anyone can apply. Design Systematic review. Participants Eligible studies were randomised controlled trials comparing prevocational training or supported employment (for people with severe mental illness) with each other or with standard community care. Outcome measures The primary outcome was number of subjects in competitive employment. Secondary outcomes were other employment outcomes, clinical outcomes, and costs. Results Eleven trials met the inclusion criteria. Five (1204 subjects) compared prevocational training with standard community care, one (256 subjects) compared supported employment with standard community care, and five (484 subjects) compared supported employment with prevocational training. Subjects in supported employment were more likely to be in competitive employment than those who received prevocational training at 4, 6, 9, 12, 15, and 18 months (for example, 34% v 12% at 12 months; number needed to treat 4.45, 95% confidence interval 3.37 to 6.59). This effect was still present, although at a reduced level, after a sensitivity analysis that retained only the highest quality trials (31% v 12%; 5.3, 3.6 to 10.4). People in supported employment earned more and worked more hours per month than those who had had prevocational training. Conclusion Supported employment is more effective than prevocational training at helping people with severe mental illness obtain competitive employment.

Background Unemployment rates are high amongst people with severe mental illness, yet surveys show that most want to work. Vocational rehabilitation services exist to help mentally ill people find work. Traditionally, these services have offered a period of preparation (Pre-vocational Training), before trying to place clients in competitive (i.e. open) employment. More recently, some services have begun placing clients in competitive employment immediately whilst providing on-the-job support (Supported Employment). It is unclear which approach is most effective. Objectives To assess the effects of Pre-vocational Training and Supported Employment (for people with severe mental illness) against each other and against standard care (in hospital or community). In addition, to assess the effects of: (a) special varieties of Pre-vocational Training (Clubhouse model) and Supported Employment (Individual Placement and Support model); and (b) techniques for enhancing either approach, for example payment or psychological intervention. Search methods Searches were undertaken of CINAHL (1982-1998), The Cochrane Library (Issue 2, 1999), EMBASE (1980-1998), MEDLINE (1966-1998) and PsycLIT (1887-1998). Reference lists of eligible studies and reviews were inspected and researchers in the field were approached to identify unpublished studies. Selection criteria Randomised controlled trials of approaches to vocational rehabilitation for people with severe mental illness. Data collection and analysis Included trials were reliably selected by a team of two raters. Data were extracted separately by two reviewers and cross-checked. Authors of trials were contacted for additional information. Relative risks (RR) and 95% confidence intervals (CI) of homogeneous dichotomous data were calculated. A random effects model was used for heterogeneous dichotomous data. Continuous data were presented in tables (there were insufficient continuous data for formal meta-analysis). A sensitivity analysis was performed, excluding poorer quality trials. Main results Eighteen randomised controlled trials of reasonable quality were identified. The main finding was that on the primary outcome (number in competitive employment) Supported Employment was significantly more effective than Pre-vocational Training; for example, at 18 months 34% of people in Supported Employment were employed versus 12% in Pre-vocational Training (RR random effects (unemployment) 0.76 95% CI 0.64 to 0.89, NNT 4.5). Clients in Supported Employment also earned more and worked more hours per month than those in Pre-vocational Training. There was no evidence that Pre-vocational Training was more effective in helping clients to obtain competitive employment than standard community care. Authors’ conclusions Supported employment is more effective than Pre-vocational Training in helping severely mentally ill people to obtain competitive employment. There is no clear evidence that Pre-vocational Training is effective.

HTA NHS R&D HTA ProgrammeT he NHS R&D Health Technology Assessment (HTA) Programme was set up in 1993 to ensure that high-quality research information on the costs, effectiveness and broader impact of health technologies is produced in the most efficient way for those who use, manage and provide care in the NHS.Initially, six HTA panels (pharmaceuticals, acute sector, primary and community care, diagnostics and imaging, population screening, methodology) helped to set the research priorities for the HTA Programme. However, during the past few years there have been a number of changes in and around NHS R&D, such as the establishment of the National Institute for Clinical Excellence (NICE) and the creation of three new research programmes: Service Delivery and Organisation (SDO); New and Emerging Applications of Technology (NEAT); and the Methodology Programme.This has meant that the HTA panels can now focus more explicitly on health technologies ('health technolo...

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.
