1. Trevor Foster GIS Manager NHS South West Commissioning Support Overview of SWCS GIS Service
2. South West Commissioning Support (SWCS) GIS and Mapping Service • What is GIS? • About us • How GIS is used in healthcare - Example analysis and maps • Demonstration - HealthGIS Maps (online mapping portal) – BNSSSG CCGs project – GP Finder – MapCat (map catalogue) • Case study examples
3. What is GIS? • Geographic Information System (Wikipedia): – “GIS is the merging of cartography, statistical analysis, and database technology” – “integrates, stores, analyses and displays geographic information for informing decision making” • Data management and preparation – maps and health data • Geocoding/georeferencing • Analysis – statistical, spatial • Thematic styling • Layers; Admin boundaries, road network, sites, people
4. Helps support business decision making Around: Using: • Contract management • Performance monitoring • Service review/development • Public Health • Commissioning • Estate planning & facilities mgt • Emergency planning • Travel & Access analysis • Ordnance Survey digital data/maps • Population statistics • Patient distribution • GP and Hospital activity data ------------------------------ • MapInfo Professional • Cadcorp SIS • RouteFinder • Visography TRACC (public transport) • What is GIS “Everything happens somewhere” “80% of data has a geographical component”
5. SWCS - GIS and Mapping Service • Formerly Avon IM&T Consortium - moved to South West CSU in 2013 • Supporting Avon HA/PCTs/CCGs since 1995 • Ordnance Survey licensing - OpenData & PSMA (2010/11) • Growth in demand from wider NHS • Developed team of specialised GIS analysts/developers • Traditional GIS analysis and mapping • HealthGIS Maps (on-line mapping portal) • Licensed partner with Ordnance Survey (May 2014)
6. • Bristol, North Somerset, South Glos, Somerset CCGs, Area Team • Other Area Teams – East Anglia (Serco), Shropshire & Staffs • Strategic Clinical Network (SW) – formerly Avon, Som, Wilts + Peninsula, Dorset, 3 Counties (Glos) cancer networks • Public Health depts in Local Authorities – Avon, Wiltshire, Dorset • Community Health – Bristol, North Somerset, South Gloucestershire, Sirona Care & Health • PCC (Primary Care Commissioning) • NHS Property Services (BNSSSG) • Mental Health Trust (NW London) • Ad-hocs; Acute Trusts, BBC Children in Need, NHS Scotland Customers
7. Contract management • GP contract map • Where GIS started in Avon – mid 90’s • Patient details from ‘Exeter System’ registration database • Postcodes • Graduated symbols thematic • Options to include age/sex
8. • Surgery location • Contractual area • Registered patients • Drive-time areas (peak-time) for (10, 15 minutes) • No. & % patients in each area GP Outer Areas
9. • Final map • Contractual area • Registered patients • Outer Area boundary • Proposal by practice • No. & % patients in each area GP Outer Areas Project
10. Service development • Number of overlapping practice areas across PCT • PCT aims to provide choice of at least 2 practices to each patient Number of GP practices Population covered Population % 0 0 0.0 1 6,504 2.4 2 18,178 6.8 3 57,755 21.6 4 67,946 25.4 5 or more 117,298 43.8 Total 267,681
11. Service development • Planned housing development areas • Supplemented with travel access analysis
12. • Quarterly/monthly performance monitoring reports • Vacc & Imms, Cancer screening • RAG (Red, Amber, Green) traffic lights for targets achievement Performance monitoring
13. • CQUIN scheme – Equity of Access • Ambulance response times “A8” performance by division • Top 10 through to Bottom 10 performing divisions • “identify 10 rural areas with significant variance against the performance in the urban centres” Performance monitoring
14. Commissioning Services – community provider • Community nurse teams • Individual visits • Shows overlapping areas • Used to define/review team members/areas
15. Commissioning Services – community provider • Community nurse teams for 1 selected day • Individual visits for 7 teams • Visit locations and order • Categorised by staff member and by Job Band • Also plot actual and optimum routes taken
16. • Head & Neck cancer review • Service provider sites • Actual patient attendances by site • Spidergrams show ‘as the crow flies’ (Euclidean) distance travelled Commissioning Services
17. • Somerset GP Out of Hours • Service provider sites • No. calls by type • Deprivation • Population density Commissioning Services
18. • Service reconfiguration • Impact assessment after new hospital opened • Change in Emergency Dept attendance rates Commissioning Services
19. • Wiltshire Vascular Surgery service review • Commissioned by Wiltshire Public Health • Service provider sites • Drive-time isochrones • Salisbury District Hospital Travel network analysis
20. Travel network analysis • Composite drive- time zones to any hospital site • Identify gaps in service availability • Plus, analysis by ‘blue-light’ drive- time • Public transport, walking options
21. Travel network analysis • Population number and % within drive-time zone • ONS national mid-year population estimates Wiltshire population with access to Vascular Surgery hospital - Average Car Travel Hospital RUH Bath Salisbury Southampton Combined (all hospitals) Number % Number % Number % Number % 0-15 minutes 0 0.0% 23,248 5.1% 0 0.0% 23,248 5.1% 15-30 minutes 7,899 1.7% 51,961 11.3% 1,832 0.4% 59,860 13.0% 30-45 minutes 128,739 28.0% 49,762 10.8% 11,621 2.5% 188,305 41.0% 45-60 minutes 119,539 26.0% 62,883 13.7% 50,497 11.0% 143,977 31.3% 60-75 minutes 79,844 17.4% 109,819 23.9% 56,079 12.2% 44,445 9.7% 75-90 minutes 95,977 20.9% 105,723 23.0% 29,649 6.4% 0 0.0% >90 minutes 27,837 6.1% 56,439 12.3% 310,157 67.4% 0 0.0% Total Wiltshire Population 459,835 ? If target = 60 minutes • 40% access Salisbury • 90% access any hospital
22. Case Study Community Service Review
23. Community Service Review Main condition or treatment patients admitted for? • Inpatients split by treatment specialty • Pie symbols at each community hospital Interpretation • Minehead inpatients have more variety • Question classification, as most appears as General Medicine • South Somerset all similar size and doing the same thing
24. Community Service Review Patient’s distance from home to community hospital? • Spidergram show distribution Interpretation • All sites have significant number of patients travelling long distances • Appear to be no outliers Questions • What percentage of people are treated near to home?
25. Community Service Review Population density • Persons per hectare by LSOA Interpretation • Community hospitals are generally located in areas of high population density except when there is an acute hospital
26. Community Service Review • Hospital catchment areas • Calculated by travel times • Stats: – Population – Inpatients – Bed occupancy rate
27. Community Service Review • Number of patients in/outside catchment area Interpretation • Williton and Shepton Mallet have very low proportion of patients within catchment area
28. Community Service Review Delayed discharges • Pie symbols with volume and reason for delay Interpretation • Significant variation between sites • Question over consistent classification • Interesting relationship between delayed discharges and location of care homes
29. Community Service Review Care Homes • Care homes, and care homes with nursing Interpretation • Large number of care homes in Minehead for its population
30. Community Service Review Attendance at MIU and A&E by postcode • Ratio of attendance • Locations of MIU and A&E services Interpretation • 75% of people use MIU when they live near one • Wincanton MIU is the exception to this
