Abstract

Aim: The aim of this study is to estimate the causally attributable one-year healthcare costs for individuals getting a type 2 diabetes diagnosis compared to a matched sample and show the incurred costs of medication and in primary and secondary healthcare.

Methods: Causal estimation using a difference-in-differences design to estimate the one-year health care costs attributable to type 2 diabetes. Danish registry data consisting of the entire population in years 2016-2019. Newly diagnosed individuals with type 2 diabetes in 2018 were identified using a validated method. Sociodemographic and historical health data were used to identify a matched control group. Individuals were followed for two years before and one year after the date of diagnosis using. Three cost components were analysed: medication and primary and secondary healthcare costs.

Results: A total of 18,133 individuals were diagnosed with type 2 diabetes in 2018 and matched successfully 1:1 to a control group. The total attributable one-year cost of type 2 diabetes was EUR 1316. The main cost component was hospital care (EUR 1004) and primary care (EUR 167). The total attributable cost of incident diabetes in Denmark in 2018 was approx. EUR 24 million.

Conclusions: The majority of the first year health care cost of incident diabetes is incurred at the hospital level followed by primary care and medication. Our yearly cost estimate per newly diagnosed is considerably lower than estimates from the US and Australia.

2 型糖尿病患者一年的医疗成本：丹麦全民差异研究。

目的：本研究旨在估算与匹配样本相比，确诊为 2 型糖尿病的患者一年的因果关系医疗成本，并显示在药物治疗以及初级和二级医疗保健中产生的成本：方法：采用差异设计进行因果估算，估算 2 型糖尿病一年的医疗成本。丹麦登记数据包括 2016-2019 年的全部人口。2018年新确诊的2型糖尿病患者是通过验证方法确定的。社会人口学和历史健康数据用于确定匹配的对照组。在诊断日期前两年和诊断日期后一年对患者进行随访。分析了三个成本组成部分：药物、初级和二级医疗保健成本：2018年共有18133人被诊断为2型糖尿病，并与对照组进行了1:1的成功匹配。2型糖尿病一年的可归因总成本为1316欧元。主要成本构成是医院护理（1004欧元）和初级护理（167欧元）。2018年丹麦糖尿病发病的总可归因成本约为2400万欧元：糖尿病事件第一年的医疗成本大部分发生在医院层面，其次是初级保健和药物治疗。我们对每位新诊断患者的年度成本估算大大低于美国和澳大利亚的估算。

期刊介绍： Diabetic Medicine, the official journal of Diabetes UK, is published monthly simultaneously, in print and online editions. The journal publishes a range of key information on all clinical aspects of diabetes mellitus, ranging from human genetic studies through clinical physiology and trials to diabetes epidemiology. We do not publish original animal or cell culture studies unless they are part of a study of clinical diabetes involving humans. Categories of publication include research articles, reviews, editorials, commentaries, and correspondence. All material is peer-reviewed. We aim to disseminate knowledge about diabetes research with the goal of improving the management of people with diabetes. The journal therefore seeks to provide a forum for the exchange of ideas between clinicians and researchers worldwide. Topics covered are of importance to all healthcare professionals working with people with diabetes, whether in primary care or specialist services. Surplus generated from the sale of Diabetic Medicine is used by Diabetes UK to know diabetes better and fight diabetes more effectively on behalf of all people affected by and at risk of diabetes as well as their families and carers.”
