1. Main Points
Intensive Intervention and Risk Management Services (IIRMS) are a type of intervention service offered by the Offender Personality Disorder (OPD) Pathway – a jointly funded partnership between His Majesty’s Prison and Probation Service and NHS England aiming to reduce risk associated with serious reoffending and improve mental health within a high-risk, high-harm cohort likely to meet the clinical threshold for a diagnosis of ‘personality disorder’. IIRMS are community-based services delivering individually tailored and psychologically informed interventions directly to people who satisfy the criteria for the OPD pathway, to manage risk of serious harm and reoffending, and develop psychological wellbeing and social engagement.
IIRMS are delivered nationally, offering 6-month period of pre-release work in custody in order to build effective professional relationships, provide practical and social support upon release from prison, as well as psychoeducation sessions where required. IIRMS operate alongside other OPD pathway services in custody, community and health settings.
The table below shows a summary of the number of individuals in England and Wales, subject to the criminal justice system, who were accessing Intensive Intervention and Risk Management Services (IIRMS) as part of the Joint HMPPS and NHS Offender Personality Disorder (OPD) Pathway and whether they were currently in custody or on probation, at the end of Quarter 3, as of 30 January 2024.

2. Notes
These figures have been drawn from an administrative IT system which, as with any large-scale recording systems, are subject to possible errors with data entry and processing, and are based on a snapshot moment in time. Validation of the data has been undertaken, however there will be a degree of inherent inaccuracy. Despite carrying out validation within the statistical processes following extraction, the data is subject to some inaccuracies inherent in any large-scale data recording system (e.g. mistyped data entries). However, the validation procedures are deemed to be proportionate in reliably minimising the impact that any errors may have on these estimates.
