Background: To evaluate the cost of diabetes related micro- and macrovascular complications in Iranian people\r\nwith type 2 diabetes mellitus.\r\nMethods: In routine clinical practice, people with type 2 diabetes mellitus were assessed for 10 years at a diabetes\r\ncare center. The type of medications and clinical data were extracted from patientsâ�� documents. Mortality rate and\r\nthe incidence of micro- and macrovascular complications recorded in patientsâ�� documents were analyzed. Cost\r\nanalysis was comprised of 1) para clinic costs as well as laboratory, medications, clinical visits and nonmedical costs\r\n2) inpatient costs as well as hospital admission costs, disability, and mortality costs.\r\nResults: From 1562 people with type 2 diabetes mellitus, a total of 1000 patients with mean duration disease of\r\n11.2 years, who had completed information in their documents, were studied. All people were free from complications\r\nat baseline. Mean cumulative incidence of diabetes-related complications over 10 years were 10.9 �± 3.5%, 8.0 �± 3.1%,\r\n4.6 �± 1.7%, 9.1 �± 3.6% and 2.3 �± 0.9% for peripheral neuropathy and diabetic foot ulcer, nephropathy, ophthalmic\r\ncomplications, cardiovascular disease and death, respectively. People with better glycemic control had less complication\r\nand also related expenditures. Average para clinic cost per patient was 393.6 �± 47.8 and average inpatient cost per\r\npatient was 1520.7 �± 104.5 USD.\r\nConclusions: Our findings demonstrate considerable incidence of diabetes chronic complications and also high health\r\ncare expenditure for related complications among our patients. As the number of people with diabetes continues to\r\nrise, early detection of the disease and implementation of timely and appropriate therapeutic strategies could decrease\r\nthe burden of diabetes chronic complications and also huge related expenditures.
