Patient-centered outcomes of a value-based insurance design program for patients with diabetes.

Value-based insurance design (VBID) initiatives have been associated with modest improvements in adherence based on evaluations of administrative claims data. The objective of this prospective cohort study was to report the patient-centered outcomes of a VBID program that eliminated co-payments for diabetes-related medications and supplies for employees and dependents with diabetes at a large health system. The authors compared self-reported values of medication adherence, cost-related nonadherence, health status, and out-of-pocket health care costs for patients before and 1 year after program implementation. Clinical metrics and satisfaction with the program also are reported. In all, 188 patients completed the follow-up evaluation. Overall, patients reported a significant reduction in monthly out-of-pocket costs (P<0.001), which corresponded to a significant reduction in cost-related nonadherence from 41% to 17.5% (P<0.001). Self-reported medication adherence increased for hyperglycemic medications (P=0.011), but there were no apparent changes in glycemic control. Overall, 89% of participants agreed that the program helped them take better care of their diabetes. The authors found that a VBID program for employees and dependents with diabetes was associated with self-reported reductions in cost-related nonadherence and improvements in medication adherence. Importantly, the program was associated with high levels of satisfaction among participants and strongly perceived by participants to facilitate medication utilization and self-management for diabetes. These findings suggest that VBID programs can accomplish the anticipated goals for medication utilization and are highly regarded by participants. Patient-centered outcomes should be included in VBID evaluations to allow decision makers to determine the true impact of VBID programs on participants.
