title: Supported housing for people with severe mental disorders.
abstract: BACKGROUND
  There has been a significant reduction in the number of people with severe mental illness who spend extended periods in long-stay hospitals. Psychiatric and social services, both statutory and voluntary, aim to assist these people to stay in their local community. District health authorities, local authorities, housing associations and voluntary organisations are jointly expected to provide support for people with severe mental disorder/s. This 'support' may well involve some sort of special housing.
  
  
  OBJECTIVE
  To determine the effects of supported housing schemes compared with outreach support schemes or 'standard care' for people with severe mental disorder/s living in the community.
  
  
  METHODS
  Cochrane Schizophrenia Group's Register of trials (February 2001) and the Cochrane Library (Issue 1, 2001) were searched using relevant phrases. These databases are compiled by methodical searches of BIOSIS, CINAHL, Dissertation abstracts, EMBASE, LILACS, MEDLINE, PSYNDEX, PsycINFO, RUSSMED, Sociofile, supplemented with hand searching of relevant journals and numerous conference proceedings. Reference list screening of relevant papers was performed.
  
  
  METHODS
  Relevant randomised, or quasi-randomised, trials dealing with people with 'severe mental disorder/s' allocated to supported housing, outreach support schemes or standard care focusing on outcomes of service utilisation, mental state, satisfaction with care, social functioning, quality of life, and economic data, were sought.
  
  
  METHODS
  Studies were reliably selected, quality rated and data extracted. For dichotomous data, relative risks (RR) would have been estimated, with the 95% confidence intervals (CI). Where possible, the number needed to treat statistic (NNT) was to have been calculated. Analysis would have been by intention-to-treat. Normal continuous data were to have been summated using the weighted mean difference (WMD). Scale data were to have been presented for only those tools that had attained pre-specified levels of quality. Tests of heterogeneity and for publication bias were to have been undertaken.
  
  
  RESULTS
  No studies met the inclusion criteria although 139 citations were acquired from the searches.
  
  
  CONCLUSIONS
  Dedicated schemes whereby people with severe mental illness are located within one site or building with assistance from professional workers have potential for great benefit as they provide a 'safe haven' for people in need of stability and support. This, however, may be at the risk of increasing dependence on professionals and prolonging exclusion from the community. Whether or not the benefits outweigh the risks can only be a matter of opinion in the absence of reliable evidence. There is an urgent need to investigate the effects of supported housing on people with severe mental illness within a randomised trial.
