impact of an alternative to incarceration by housing and support by assertive community treatment team for homeless people with severe psychiatric disorders referred to immediate referral procedure: ailsi program

Conditions: Severe Psychiatric Disorder

Summary: people who are homeless with severe psychiatric disorders have to negotiate discontinuous mental health care pathways including high use of emergency departement and enforced hospitalisation, poor access to ambulatory care, poor access to common rights services and a greater risk of incarceration. in order to reduce morbidity, improve social integration and outpatient care for people with severe psychiatric disorders and multiple factors of social vulnerability, the concept of therapeutic jurisprudence has led to the emergence of mental health courts in anglo-saxon nations. these courts aim to condition alternatives to incarceration through community-based intensive care (assertive community treatment-act). act teams offer direct access to housing without any prerequisite of treatment or abstinence. this model of community-based intensive care tends to demonstrate medical and legal effectiveness while being associated with greater care acceptability by patients. in france, very little data exists on the subject. médecins du monde (ngo), in collaboration with the public prosecutor's department of marseille, proposes the implementation of the ailsi strategy for people who homeless with severe psychiatric disorders and referred to immediate referral procedure. the research unit ea 3279 - ceress is in charge of the independent evaluation of this innovative intervention. this is an randomized coontrolled study, with two groups: ailsi group (intervention) and tau group (usual services). a total of 220 patients will be included (100 in the ailsi group / 120 in the tau group). the main objective is to evaluate the effectiveness of the innovative program (ailsi) compared to usual services by assessing the duration of reincarceration at 18 months in each group, weighted by exposure time. . duration of inclusion: 30 months; duration of follow-up: 18 months; total duration of the study: 54 months. both quantitative and qualitative analyses will be conducted to address overall outcomes. univariate and multivariate analyzes will be performed on the primary outcome as well as the secondary outcomes in order to highlight significant differences between the two groups and to identify predictive factors for improved effectiveness. the analysis will be conducted in accordance with good epidemiological practices, and the final report will be written according to the consort (consolidated standards of reporting trials) recommendations.
