Short-term societal economic burden of first-incident type 2 diabetes-related complications - a nationwide cohort study

Background People with type 2 diabetes are at increased risk of developing diabetes-related complications and the augmented societal costs increase with the severity of complications. The objective was to estimate the short-term attributable societal costs of the first event of specific diabetes-related complications amongst people with type 2 diabetes. Methods The study was based on national registry data covering all patients with type 2 diabetes in Denmark. Attributable costs of each event were calculated as the difference between costs of patients with the specific event and costs incurred by their controls. Results were reported for the incidence year and the following two years. Results On average, 13,054 patients were identified annually from 2007 to 2013 with one or more of 17 specific first-incident diabetes-related complications. The attributable healthcare costs amounted to 114 million EUR annually in the incidence year alone. Costs were highest in the incidence year but were significantly higher also in the 2(nd) and 3(rd) year, driven particularly by increased indirect costs. Conclusions Short-term excess costs of treating specific first-incident diabetes-related complications are massive for society. Our study highlights the importance of strengthening primary prevention within type 2 diabetes to minimize the risk of developing costly diabetes-related complications.
