Prison-based democratic therapeutic communities, medication, and the power to exclude.

In 1962, the first custodial Democratic Therapeutic Community (DTC) was established in the English prison estate at HMP Grendon. Today, the Category B male prison estate in England and Wales has three DTCs and three 'TC+' units for prisoners with learning disabilities. There is one DTC in the female estate at HMP Send. The services fall under the remit of the Offender Personality Disorder Pathway, a jointly commissioned initiative that aims to provide a pathway of psychologically informed services for a highly complex and challenging group of prisoners who are likely to have a severe personality disorder. Several of these units make clear that prisoners prescribed psychotropic medicines are specifically excluded from entry and participation in the available therapy. This analysis paper explores whether an evidence-based rationale exists for this practice and examines the impact on those whose care pathways may comprise hospitals and prisons.
