Visualising and analysing geographical patterns in mental illness can be a starting point for understanding and creating effective policy around inequalities and how to resolve them. The paper aims to discuss these issues.
This research note looks at geographical variations in GP drug prescribing for schizophrenia and similar psychosis using open Presentation-level Data for England downloaded from NHS Digital.
The authors found considerable geographical variation in both the level of prescribing per thousand population at local authority level and in the rate of change measured over five years. There is a statistically significant north-south divide in prescribing. The authors have used social marketing geodemographics to explore possible correlates with the geographical patterns. Highest positive correlations show links to deprivation and less healthy lifestyle choices.
This is the first time National maps of geographical variation of GP prescribing for schizophrenia and psychosis have been produced. Seeing this geographical variation is in itself informative and a potential eye-opener. In doing so, new questions can be asked of the data, practice and policy.
