GIS mapping of healthcare practices: do older adults have equitable access to dental and medical care in the UK?

Introduction Considering an ageing population with increasing comorbidities, access to oral and general healthcare is a growing concern. This study aimed to identify and compare access to dental and general practices. This study further aimed to ascertain if there exists a socioeconomic distribution of dental and general practices among older adults. Materials and methods A total of 13,007 dental practices and 13,759 general practices were mapped using geographic information system software, and overlaid with the UK older adult population and deprivation data by health areas. Data analysis was carried out by creating a geographical distribution map and by using descriptive statistics, Gini coefficients and Lorenz curves. Results NHS Central London Clinical Commissioning Group (CCG) held the highest dental practice-to-population ratio of 958 practices per 100,000 older adults, while NHS Manchester CCG held the highest general practice-to-population ratio of 264.4 general practices per 100,000 older adults. England had the highest Gini coefficients for general and dental practice at 0.214 and 0.195, respectively. Both dental and general practices were socioeconomically distributed among older adults in England, Wales and Northern Ireland, but not in Scotland. Conclusions An increasing proportion of older adults need access to healthcare that is based on clinical need, not the ability to pay; a founding principle of the NHS. This nation-wide study captures inequities in the spatial accessibility for older adults in the UK.
