Common and severe mental illness

Mental health is a high public health priority area.

Common mental health disorders are conditions that cause marked emotional distress and interfere with daily function, but do not usually affect a person's cognition, insight and perception of reality. They comprise different types of depression and anxiety, and include obsessive compulsive disorders. Severe mental illness includes schizophrenia, bipolar affective disorder and other psychoses. 

Key findings

Figures from the Quality and Outcomes Framework (QOF) 2020/21 (unless stated otherwise) show that:

  • In the Lancashire-12 area, there are 149,611 adults (aged 18+ years) with a confirmed diagnosis of depression, accounting for 15.0% of the total 18+ registered population. This is higher than the England prevalence of 12.3%.
  • In Blackburn with Darwen (21,420|15.7%) and Blackpool (28,009|19.8%) the prevalence of QOF recorded adult depression is also above the England average.

For CCG, county and unitary data and further information please see below. If the area has defaulted to 'Counties & UAs in North East region', click on the down arrowhead next to 'Geography', select 'Region' and then 'North West'. This is an issue which is not within our control, apologies.
