How Health Maps Wales is helping to uncover patterns, trends and variation in health outcomes through the visual analysis of data
The NHS Wales Informatics Service (NWIS) collects and manages data held in a wide range of national datasets on behalf of NHS Wales and the Welsh government. This includes hospital admissions data, the National Community Child Health Database (NCCHD), outpatient attendances as well as birth and death registrations.
NWIS wanted to develop a ‘one-stop shop’ to improve access to this data and also provide a more complete picture of health for public health professionals and commissioners in small regions. It felt that low-level geographic maps using Census output areas would give them a better understanding of their local health needs and inform spending plans.
NWIS developed an interactive tool called Health Maps Wales in collaboration with the Welsh government to map a range of health indicators within broad categories.
