This indicator measures the average network distances and times to the nearest GP practice across Lower Super Output Areas in England since 2011.
GP practice addresses of openly available monthly data acquired from the NHS digital (https://digital.nhs.uk/data-and-information/publications/statistical/practice-level-prescribing-data) and NHS Business Services Authority (https://www.nhsbsa.nhs.uk/prescription-data/prescribing-data) services. Next, the GP practice address data transformed to active GP practice addresses (GP practices that written NHS prescriptions in England and dispensed in the community) for each year since 2011.
Using the active GP practice addresses for each year, network distances to the nearest GP practice by year derived for each postcode (National Statistics Postcode Lookup (NSPL) - https://geoportal.statistics.gov.uk/datasets/national-statistics-postcode-lookup-august-2020-1/about) in England using the Routino open source software (https://www.routino.org). Routino is an application for identifying the shortest path National Statistics Postcode Lookup (NSPL) - https://geoportal.statistics.gov.uk/datasets/national-statistics-postcode-lookup-august-2020-1/about between two locations using the Open Street Map transport network and considers directional restrictions on roads as well as attached labels of speed limits and barriers. The network distances/times between each postcode and the postcode of the nearest GP practice have been aggregated from postcode level into the Lower Super Output Area (LSOA) level by taking the average of network distances/times across the postcodes (mean value).
