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 - prevalence

The following findings are for common mental illness (including depression and anxiety).

Figures from the 2016/17 Quality and Outcomes Framework (QOF) indicate that there are 155,554 adults (aged 18+) with a confirmed diagnosis of depression, accounting for 11.2% of the total 18+ registered population across the Lancashire and South Cumbria Sustainability and Transformation Plan (STP) area. All eight clinical commissioning groups (CCGs) have a recorded prevalence significantly above the England average (9.1%). There is wide variation in the level of depression prevalence at GP practice level, ranging from 21.4% to 1.0%. Additionally, there were 27,252 patients (aged 18+) added to the depression registers for the first time during the 2016/17 period. 

The following findings are for severe mental illness.

Figures from the 2016/17 QOF indicate that there are 18,608 persons on the mental health registers (includes persons with schizophrenia, bipolar affective disorder and other psychoses) across the Lancashire and South Cumbria STP area, accounting for 1.1% of the total registered population. Further analysis shows that five of the eight CCGs have a significantly higher prevalence of severe mental health illness than the England average (0.9%). These are NHS Blackburn (1.3%), NHS Blackpool (1.6%), NHS East Lancashire (1.1%), NHS Fylde and Wyre (1.1%) and NHS Greater Preston (1.0%).

Across GP practices there is a wide variation in the registered prevalence of severe mental health problems, ranging from 2.8% to 0.4%
