In response to the Winterbourne scandal, and the large number of people with intellectual disabilities (IDs) and offending behavior being treated in psychiatric hospitals, this study identified the domains that should be used to measure treatment outcomes of this group.

A systematic search of relevant databases was undertaken to identify domains. Sixty studies met the eligibility criteria, and findings were synthesized using content analysis. The findings were refined within a consultation and consensus exercises with carers, service users, and experts.

The final framework encompassed three a priori super-ordinate domains (a) effectiveness, (b) patient safety, and (c) patient and carer experience. Within each of these, further sub-domains emerged from our systematic review and consultation exercises. These included severity of clinical symptoms, offending behaviors, reactive and restrictive interventions, quality of life and patient satisfaction.

To index recovery, services need to measure outcome using this framework.
