Grintsova O, Maier W, Mielck A. Inequalities in health care among patients with type 2 diabetes by individual socio-economic status (SES) and regional deprivation: a systematic literature review. 2014, International Journal for Equity in Health; 13:43. doi:10.1186/1475-9276-13-43.

This systematic review points out that socio-economic inequalities in diabetes care and low individual SES and residential area deprivation are often associated with worse process indicators and worse intermediate outcomes, resulting in higher risks of microvascular and macrovascular complications. These inequalities exist across different health care systems. Recommendations for further research are provided.
