Examining morbidity and mortality trajectory profiles of hypertension, diabetes and dementia across healthcare systems: an analysis of Catalan and German administrative medical data for the years 2010 to 2019

Profound differences in prevalence as well as in morbidity and mortality trajectories existed between Catalonia and Germany between 2010 and 2019, reflecting more favorable health outcomes in Catalonia. Although administrative medical data yield meaningful insights for each population, comparing results across populations demands careful attention to variations in healthcare systems. To fully realize the potential of a European health data space, efforts are required to further harmonize data.
