Text: We used two dataets for these analyses.  A local sample was drawn from residents in Barking and Dagenham. De-identified data on their use of health and care services was available from linked data from local government services, health providers and health commissioners in the area. Information about accessing the data can be found here: https://www.carecity.london/your-blog/180-linking-datasets-for-better-population-health-management   A national sample was drawn from the Clinical Practice Research Datalink (CPRD). Data access for this project has been approved (ISAC 17_150RMn2). Data used for this analysis is not publically available but anonymised patient datasets can be extracted for researchers against specific study specifications, following protocol approval from the Independent Scientific Advisory Committee (ISAC) https://www.cprd.com/<|eot_id|><|start_header_id|>assistant<|end_header_id|>
