ObjectiveDemographic and infrastructural developments might compromise medical care provision in rural regions, particularly for acute health conditions. Studying the case of myocardial infarction (MI), we investigated how MI-related mortality at ages 65+ varies between rural and urban regions in Germany and to what extent differences are driven by varying case fatality and disease incidence.MethodsThe study relies on data containing all hospitalizations, cause-specific deaths and population counts for the total German population between years 2012-2018 and ages 65+. MI-related mortality, MI incidence and case fatality are compared between urban and rural regions in a population-wide analysis. The impacts of changing incidence and case fatality on rural-urban MI-related mortality differences are assessed using a counterfactual approach.ResultsRural regions in Germany show systematically higher MI-related death rates and MI incidence at ages 65+ compared to urban regions. Higher mortality is primarily the result of higher MI incidence in rural regions, while case fatality is largely similar. The rural excess in MI-related death rates would be nullified and 1 out of 6 MI-related deaths in rural regions could be prevented if rural regions in Germany would have at least the median MI incidence of urban regions.ConclusionsMI incidence and not case fatality drives the rural disadvantage in MI-related mortality in Germany. Higher MI incidence points towards potential regional variation in the effectiveness of disease prevention. The findings highlight that improving disease prevention at the patient level carries larger opportunities for reducing regional MI-related mortality inequalities in Germany.Copyright © 2024 The Authors.
