Case Study: South West Commissioning Support keeps Yeovil Hospital stroke services open with Ordnance Survey data

South West Commissioning Support - Customer Case Study

Somerset Clinical Commissioning Group needed to assess how a proposed centralised stroke service at Taunton Hospital would affect patients across the large county and whether closing Yeovil’s stroke service was clinically and logistically viable. They turned to Ordnance Survey (OS) data under the Public Sector Mapping Agreement (PSMA) — including products such as Code-Point Open, AddressBase Plus and Boundary-Line — to provide the detailed geographic and postcode information required for travel-time analysis.

The South West Commissioning Support (SWCS) GIS team combined Ordnance Survey data with MapInfo Professional, RouteFinder and Basemap’s TRACC to model blue-light emergency travel times and produce maps and reports. The OS-based analysis showed many patients could not meet the 60-minute call-to-door target, supplied clear evidence for decision-makers, and directly led to the decision not to close Yeovil Hospital as a stroke centre while delivering a reproducible methodology for other areas.
