The first of its kind in the field of diabetes, this IDF Europe study highlights constraints and disparities in access to medicines and medical devices for diabetes care in 47 European countries. Based on over 1,150 answers to a survey questionnaire, interviews and desk research, it aims to provide evidence to policy makers and stakeholders on the bottlenecks and inequalities faced by people living with diabetes in terms of access to the treatment they need. The study assesses key dimensions of access (availability, accessibility, affordability, quality and equity) to a range of treatment options used in diabetes care at country level, while offering a comparative, regional perspective that may inspire new solutions based on other countries’ experiences.
