Evidence that value-based insurance can be effective
Value-based insurance design reduces patient copayments to encourage the use of health care services of high clinical value. As employers face constant pressure to control health care costs, this type of coverage has received much attention as a cost-savings device. This paper's examination of one value-based insurance design program found that the program led to reduced use of nondrug health care services, offsetting the costs associated with additional use of drugs encouraged by the program. The findings suggest that value-based insurance design programs do not increase total systemwide medical spending.
Impact of decreasing copayments on medication adherence within a disease management environment
This paper estimates the effects of a large employer's value-based insurance initiative designed to improve adherence to recommended treatment regimens. The intervention reduced copayments for five chronic medication classes in the context of a disease management (DM) program. Compared to a control employer that used the same DM program, adherence to medications in the value-based intervention increased for four of five medication classes, reducing nonadherence by 7-14 percent. The results demonstrate the potential for copayment reductions for highly valued services to increase medication adherence above the effects of existing DM programs.
