The Dangerous and Severe Personality Disorder (DSPD) Unit at Broadmoor Hospital was closed because of high costs and low efficiency.
It housed 48 men and cost £36 million to build, and approximately £300,000 per patient per year. The Home Office now believed that such patients should be treated in prison.
The DSPD unit appears to be an expensive failure but several observers note that the experiment raised awareness about personality disordered patients and their needs.
