Reducing health inequalities in an efficient way depends on prioritising health policies according to their impact on the distribution of health across the entire population, not just on those targeted by the policy. This is because the funds used to support a health policy could have been used on other actions to improve health, potentially in different people.
Distributional cost-effectiveness analysis (DCEA) is a methodology to quantify the costs and benefits of a new health technology or health policy and how they are distributed across different population groups. DCEA helps inform policy-makers about the degree to which different population groups would gain or lose from introducing a new health policy or changing an existing policy. The method can therefore be used to assess their impact on health inequalities.
The Centre for Health Economics at the University of York has been funded by the NIHR Policy Research Programme to explore the health inequality effects of existing health policies, and to inform the design of a new health policy that incentivises the reduction in health inequalities through primary care. This CPRD research project will develop a catalogue of estimates of socioeconomic gradients in disease prevalence and the quality of primary care received under the Quality and Outcome Framework (QOF). These estimates are required to inform the DCEAs.
This study will use CPRD data for a sample of patients registered with English GP practices in two ways. First, direct standardisation against a UK reference population will be used to calculate disease prevalence rates by socio-economic group for 18 common diseases. Second, regression analysis adjusting for patients’ socio-economic group membership, age, sex, and practice fixed effects will be used to determine differences in achievement of QOF-incentivised care standards. Patients’ socio-economic circumstances will be approximated using the Index of Multiple Deprivation.
