The 30-year cost-effectiveness of alternative strategies to achieve excellent glycemic control in type 1 diabetes: An economic simulation informed by the results of the diabetes control and complications trial/epidemiology of diabetes interventions and complications (DCCT/EDIC).

ABSTRACT: OBJECTIVE:To simulate the cost-effectiveness of historical and modern treatment scenarios that achieve excellent vs. poor glycemic control in type 1 diabetes (T1DM). RESEARCH DESIGN AND METHODS:We describe and compare the costs of intensive and conventional therapies for T1DM as performed during DCCT, and modern intensive and basic therapy scenarios using insulin analogs, pens, pumps, and continuous glucose monitoring (CGM) to achieve excellent or poor glycemic control. We then assess the differences in treatment costs and the costs of outcomes over 30?years and report incremental cost-effectiveness ratios. RESULTS:Over 30?years, DCCT intensive therapy cost $127,500 to $181,600 more per participant than DCCT conventional therapy, and modern intensive therapy cost $87,700 to $409,000 more per individual than modern basic therapy. Excellent glycemic control averted as much as $90,900 in costs from complications and added ~1.62 quality-adjusted life-years (QALYs) per participant over 30?years. When costs and QALYs were discounted at 3% annually, DCCT intensive therapy and modern intensive therapies that use multiple daily injections (MDI) or pumps are cost-saving or cost-effective (<$100,000/QALY-gained). If applied to all patients with T1DM, modern intensive therapy using pumps and CGM is not cost-effective (>$250,000/QALY-gained) but would be more cost-effective if associated with less hypoglycemia, better glycemic control, fewer complications, or improved health-related quality-of-life. CONCLUSIONS:Use of the least expensive intensive therapy needed to safely achieve treatment goals for patients with T1DM represents a good value for money.

Project description:ObjectivesThe goal of these studies was to determine the association between cardiovascular autonomic neuropathy (CAN) and indices of left ventricle (LV) structure and function in patients with type 1 diabetes (T1DM) in the DCCT/EDIC (Diabetes Control and Complications Trial /Epidemiology of Diabetes Interventions and Complications) study.BackgroundThe pathophysiology of LV dysfunction in T1DM remains unclear, especially when the LV ejection fraction (EF) is preserved. Whether CAN is associated with LV dysfunction is unclear.MethodsIndices of LV structure and function were obtained by cardiac magnetic resonance imaging (CMRI). CAN was assessed by cardiovascular reflex testing (R-R response to paced breathing, Valsalva ratio, and blood pressure response to standing). Analyses were performed in 966 DCCT/EDIC participants with valid CMRI and CAN data (mean age 51 years, 52% men, mean diabetes duration 29 years, and mean glycosylated hemoglobin 7.9%).ResultsSystolic function (EF, end-systolic and end-diastolic volumes, stroke volumes) was not different in 371 subjects with CAN compared with 595 subjects without CAN. In multiple-adjusted analyses, participants with either abnormal R-R variation or a composite of abnormal R-R variation, abnormal Valsalva ratio, and postural blood pressure changes had significantly higher LV mass, mass-to-volume-ratio, and cardiac output compared with those with normal tests (p < 0.0001 for all). After further adjustment for traditional cardiovascular risk factors, subjects with abnormal R-R variation had higher LV mass and cardiac output compared with those with a normal R-R variation (p < 0.05).ConclusionsIn this large cohort of patients with T1DM, CAN is associated with increased LV mass and concentric remodeling as assessed by CMRI independent of age, sex, and other factors.
