Liaison and Diversion (L&D) services aim to identify people experiencing mental health problems, substance misuse and learning disabilities (among other vulnerabilities) as they pass through the criminal justice system to ensure their health and other needs are known about and that they are referred to services that can address their needs. 

NHS England has recently launched a National Model for L&D services to follow to ensure people experiencing mental health problems/substance misuse/learning disabilities in the criminal justice system are provided for properly across the country. The aim of this study is to assess whether the National Model for L&D has any impact on reconviction rates, diversion from the criminal justice system or the use of health services. The use of health services particularly is looking at; A&E, drug treatment, mental health treatment and outpatient services.

This study has now closed to recruitment. 


Findings so far:

The implementation of the National Model for L&D resulted in significant changes in all ten sites and was implemented within two years of operation. 

Benefits of the implementation of the National Model included the fact that the total number of people with vulnerabilities being identified increased with this information being available to the police, courts or partner agencies in a timely and relevant manner. However, there were some issues surrounding user engagement and ensuring consistency in the quality of reports from the L&D service.
