Common and severe mental illness


Mental health is a high public health priority area and addressing mental health problems in all age groups and improving outcomes and relevant services are suggested in the 2011 mental health strategy for England entitled “No health without mental health”.

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.

Key findings

The following findings for common mental illness (including depression and anxiety) apply across the eight clinical commissioning groups (CCGs) in the Lancashire-14 area:

  • An estimated 187,320 people aged 16-74 years are predicted to have a common mental health disorder.
  • 103,000 of Lancashire-14's residents (16-74) are predicted to have a mixed anxiety and depressive disorder giving an estimated prevalence of 9.5% compared to England's rate of 9.1% (2016).
  • There are 125,455 adult patients (aged 18+ years) on the depression registers, accounting for 10.3% of the 18+ registered population (Quality and Outcomes Framework (QOF) 2015/16), significantly above the England average (8.3%).
  • There is a wide variation across GP practices in the recorded prevalence of 18+ depression, ranging from 1.0% to 21.3%, with a weak positive correlation with practice deprivation. 
  • During the period 2015/16, there were 22,677 patients aged 18 and over with depression recorded on practice depression registers for the first time.  In the Lancashire-14 area, the incidence of 18+ depression is 1.9%, higher than the England average of 1.4%; in seven CCGs the incidence of 18+ depression is also higher than the England average.

The following findings for severe mental illness apply across the eight CCGs in the Lancashire-14 area:

  • The QOF 2015/16 figures indicate that the prevalence of severe mental health problems (patients with schizophrenia, bipolar affective disorder and other psychoses) is 1.04%, which is higher than the England average (0.90%).
  • There are 15,959 patients on the registers for severe mental health problems.
  • Five CCGs have a significantly higher prevalence of severe mental health problems compared to the national rate. These are: Blackpool (1.4%, 2,474), Blackburn with Darwen (1.2%, 2,082), East Lancashire (1%, 3,966), Fylde & Wyre (1%, 1,506) and Greater Preston (0.98%, 2,072).
  • Across the GP practices, there is a wide variation in the registered prevalence of severe mental health problems, ranging from 0.4% to 2.8%, with a moderate positive correlation with practice deprivation.
