Supervised Community Treatment Orders (CTOs) have been available in England and Wales as part of the new Mental Health Act from 3rd November, 2008. The empirical evidence of the effects of CTOs, however remains inconclusive. The Department of Psychiatry at the University of Oxford will conduct a randomised controlled trail of the new Supervised Community Treatment Orders. The trail will compare the new provision with what is currently available for patients who need ongoing supervision in the community.
