Aims
We assessed cardiovascular risk and drug treatment status of adults in Aotearoa New Zealand and present these data in interactive maps to inform cardiovascular risk management.
Methods
A 2013 cohort of almost all 30-74 year-old New Zealanders without cardiovascular disease was created by linking national datasets in Statistics NZ’s Integrated Data Infastructure (IDI), a repository of government and non-governmental datasets. Each person’s 5-year cardiovascular risk was predicted using policy-level risk prediction equations and their use of blood pressure lowering and lipid-lowering treatment was determined. We applied geographical maps and population cartograms for spatial representations of risk and drug treatment at the regional and subregional levels and for various population groups.
Results
We present a ‘family’ of interactive maps visualising variation in national cardiovascular risk profiles and dispensing of blood pressure-lowering and lipid-lowering medications at the regional and sub-regional level, stratified by predicted cardiovascular risk, diabetes status, gender and ethnicity.
Conclusions
We demonstrate that interactive visualisations of linked national health administrative datasets through different types of representations and scales could facilitate identification of disparities in cardiovascular risk management and implementation gaps. These visulations could support clinicians and policy makers to identify areas and population groups in most need for interventions.
Visualisation of CVD risk profiles at the national level using attribute maps
Interactive visualisation for national level information using attribute maps for Māori/Pacific with diabetes and non-Māori/Pacific with diabetes. The visualisation can be accessed at here.
Visualisation of medication dispensing for the management of CVD at the regional level using population cartograms
Interactive visualisation of medication dispensing for the management of CVD for Māori, Pacific, Indians, Other, and Europeans with diabetes at the District Health Board level using population cartograms.
Visualisation of medication dispensing for the management of CVD at the sub-regional level with a linked side-by-side geographical map and population cartogram
Interactive visualisation of medication dispensing for the management of CVD for the New Zealand population at the Super Data Zone level using linked side-by-side geographical map and population cartogram. The visualisation can be accessed at here.
