Aims

• Background to mapping project

• Uses of the maps

• Introduction to the maps

• Future plans

Background

• Increasing use of maps in public health

• Examples: – Teenage pregnancy– Hospital episodes– Cancer e-atlas

• Interactive maps make the information more accessible

Renal mapping project

• Collaboration between the Renal Registry and East Midlands Public Health Observatory

• Renal Registry reports

• Mapping software ‘instant atlas’

• On line access

Advantages of maps

• Interactive and interesting

• Can be used for:– Estimating need– Commissioning services– Identifying inequalities

• Combining data: extension of dataset beyond that held by the Registry

Current maps available- Single map

Current maps available

Single maps

• RRT prevalence (direct and indirect)

• Geography: LA or PCT

Allows:

• Trends

• Area comparisons

Current maps available- Double map

Current maps available

Double mapsAllows the investigation of correlations• RRT prevalence (direct and indirect)• Geography: LA or PCTCan compare RRT rate with other factors• Deprivation• Ethnicity• CHD mortality

Current maps available- Area Profiles

Current maps available

Area profiles

• PCT profile on one page

• Two PCTs can be compared

• Difference from national data displayed

• Currently:– Calcium– Phosphate – Parathyroid Hormone

Future maps available- Funnel plot

Future maps available

Funnel Plots

• Allow outlying areas to be identified

• Data points are plotted on a graph with the mean value and “control limits”– Within control limits are performing as

expected– Outside control limits are unexpectedly high

or low

Progress to date

Currently

• Maps produced

• On staging server (limited access)

• Looking for feedback (working group)

• Refine the maps with feedback

• Place on public website

• Increase data and update year on year
