Direct evidence, e.g. randomised or cohort studies, for the cost-benefit of provision of other specialist services is limited. However the following exist:

• Perinatal mental health services (supported by NICE)⁸⁴
• Eating disorder services:
  • especially important where these disorders are life-threatening⁸⁵
  • inpatient units have an important but limited role in comparison to community management⁸⁶
• ‘Borderline personality disorder’ services (recommended in each Trust by NICE²⁶)
• Mood disorders clinics⁸⁷
• Psychosis specialist services
• Services for specific groups, e.g. hearing impaired, autism, Attention Deficit Hyperactivity Disorder.
