Question to the Department of Health and Social Care:

To ask the Secretary of State for Health and Social Care, how many people were diagnosed with Obsessive Compulsive Disorder in each of the last five years; what types of treatment are provided to such people in secondary care; and how many such people received each treatment in each year.

The information requested is not available due to the limitations of current diagnosis data on within the Mental Health Services Dataset. Only around 20% to 25% of cases in the dataset have a specific diagnosis recorded; any data provided on obsessive compulsive disorder (OCD) diagnoses would therefore represent an undercount.

Regarding treatment types, the National Health Service may offer talking therapies and medication, such as antidepressants, separately or together. Talking therapies for OCD may include, but are not limited to, cognitive behavioural therapy, exposure and response prevention, and group therapy.

Procedure data relating to different types of treatment is recorded through the use of SNOMED codes. Not all providers are submitting SNOMED codes for the years requested and as such this incomplete data is not included in the response.
