OBJECTIVE: To estimate the direct medical costs associated with managing complications, hypoglycemia episodes, and infections associated with type 2 diabetes expressed in 2012 United States dollars (USD). METHODS: Direct data analysis and microcosting were used to estimate the costs for an event leading to either a hospital admission or outpatient care, and the post-acute care associated with managing macrovascular and microvascular complications, hypoglycemia episodes, and infections. Data were obtained from many sources, including inpatient and emergency department databases, national physician and laboratory fee schedules, government reports, and literature. Event-year costs reflect the resource use during an acute care episode (initial management in an inpatient or outpatient setting) and any subsequent care provided in the first year. State costs reflect annual resource use required beyond the first year for the ongoing management of complications and other conditions. Costs were assessed from the perspective of a comprehensive US healthcare payer and expressed in 2012 USD. RESULTS: Event-year costs (and state costs) for macrovascular complications were as follows: myocardial infarction $56,445 ($1904); ischemic stroke $42,119 ($15,541); congestive heart failure $23,758 ($1904); ischemic heart disease $21,406 ($1904); and transient ischemic attack $7388 ($179). For two microvascular complications the event-year and state costs were assumed the same: $71,714 for end stage renal disease, and $2862 blindness. The event-year cost was $9041 for lower extremity amputations, and $2147 for diabetic foot ulcers. Costs were also determined for managing hypoglycemic episodes: $176-$16,478 (depending on treatment required), and infections: vulvovaginal candidiasis $111, lower urinary tract infection $105. CONCLUSIONS: This study, which provides up-to-date cost estimates per patient, found that managing macrovascular and microvascular complications results in substantial costs to the healthcare system. This study facilitates conduct of other research studies such as modeling the management of diabetes and estimating the economic burden associated with complications.
