Background and study aims
Critical Time Intervention (CTI), a case management model, was originally developed in New York to reduce homelessness amongst those discharged from hospital suffering from a mental illness. CTI is intensive case management at times of transition, e.g. between prison and the community. In 2007, CTI was adapted for mentally ill prisoners due to be released and a study was conducted to see if CTI effectively connected these prisoners with social, clinical, housing and welfare services in the first few weeks after leaving prison. Results suggested continuity of care for prisoners with severe mental illness can be improved by working with them to identify needs prior to release, and by assisting them to engage effectively with the necessary community agencies. The main aims of this study are to establish whether a specific model of case management, Critical Time Intervention (CTI), is effective in improving engagement with health and social care services, reducing mental health hospital admissions, reducing re-offending, and reducing time in prison among released adult male prisoners with severe and enduring mental illness (SMI).
Who can participate?
Adult male prisoners due for release, with severe and enduring mental illness, who are receiving secondary mental health care in prison.
What does the study involve?
The case management model Critical Time Intervention (CTI) is compared to treatment as usual (TAU) for prisoners with mental health problems due for release. Participants are randomly allocated to either the CTI or TAU group.
What are the possible benefits and risks of participating?
If allocated to receive CTI, participants may receive extra support upon that normally provided in the treatment as usual condition, i.e. having a case manager that follows them into the community after release.
Where is the study run from?
HM Prisons Manchester, Leeds and Brixton are the research sites. The Principal Investigator is based at the University of Manchester (UK).
When is the study starting and how long is it expected to run for?
The study began in January 2012 and will run until June 2015. Recruitment will run for 18 months from September 2012.
Who is funding the study?
The National Institute for Health Research: Service Delivery and Organisation Programme (UK).

| Scientific title | Critical time Intervention for Severely mentally ill released Prisoners: a randomised control trial |
| Study acronym | CrISP |
| Study objectives | The primary aims of the project are to establish whether a specific model of case management, Critical Time Intervention, is effective in: 1. Improving engagement with health and social care services upon discharge from prison 2. Reducing mental health in-patient episodes 3. Reducing re-offending 4. Increasing community tenure through reducing time in institutional settings among released adult male prisoners with severe and enduring mental illness. |

Eligibility
| Participant type(s) | Patient |
|---|---|
| Age group | Adult |
| Sex | Male |
| Target sample size at registration | 200 |
| Key inclusion criteria | 1. Male 2. Have severe and enduring mental illness (defined as major depressive disorder, hypomania, bipolar disorder and/or any form of psychosis including schizophrenia, schizoaffective disorder and any other non-affective, non-organic psychosis) 3. Be a client of Inreach services 4. Have a release/likely release date within 6 months of randomisation to the study 5. Have at least 4 weeks left in prison after randomisation to the study |
| Key exclusion criteria | Those who do not have the capacity to consent will be excluded from the study. Arguably, these are possibly the most vulnerable prisoners with mental health problems. The research team acknowledge this potential limitation however for those individuals who do lack capacity to consent most (if not all) will be in the process of being transfered to NHS secure services or are very unlikely to be released directly into the community and therefore would not be eligible for the study given the inclusion criteria. |
