Estimation of the economic and health impact of complications of type 2 diabetes mellitus in the autonomous community of Madrid (Spain)

2014 
Abstract Objective To estimate the economic and health impact of chronic complications (macrovascular and microvascular) of type 2 diabetes mellitus (T2DM) in the autonomous community of Madrid (Spain) (ACM). Methods The number of expected complications was obtained from a descriptive, cross-sectional study on a cohort of 3268 patients with T2DM from the ACM. Cost of complications (€, 2012) was assessed both at hospitals and in primary care. The number of medical visits in primary care and drug treatment for complications were collected by a panel of 21 physicians experienced in treatment of T2DM. Population and epidemiological data and healthcare costs were obtained from Spanish sources. Univariate sensitivity analyses were performed. Results It is estimated that there are 390,944 patients with T2DM in the ACM, and that they experience 172,406 and 212,283 macrovascular and microvascular complications respectively during their lifetimes. Mean cost of T2DM complications per patient is estimated at €4121.54 (66% due to macrovascular complications). The economic impact of T2DM complications in the ACM would be €1611 million (1065 and 545 millions from macrovascular and microvascular complications respectively). The economic impact would range from €1249 and 2.509 million euro depending on T2DM prevalence. Conclusions Complications of T2DM have a great health and economic impact in ACM.
