Many countries and health systems are struggling with growing healthcare expenditures in general, and those for prescription drugs in particular. The USA is no exception, with pharmaceutical spending per capita above that of any other Organisation for Economic Co-operation and Development country. 1 Cost-sharing through copayments or coinsurance is a common approach to attempt to manage drug spending and utilisation. However, although cost-sharing reduces potentially unnecessary medication use, 2 it also reduces adherence to needed medications. Reduced adherence can lead to long-term health detriments and to offsetting costs. 3–5 The effects of cost-sharing may be exacerbated among low-income individuals. 6 7Most previous studies of the impact of cost-sharing on adherence have focused on patients who have filled a prescription at least once. In contrast, there are fewer studies focused on adherence to filling the initial prescription. In this issue, the study by Aznar-Lou et al 8 adds to the medication adherence literature by demonstrating that initial medication non-adherence (IMNA; not filling a prescription when a medication is first prescribed) is similarly sensitive to costsharing levels, and that this relationship persists across income levels. The study’s findings provide further support for the potential benefit of value-based insurance design (VBID), which is the idea of reducing cost-sharing for more valuable medications that can prevent downstream complications, typically for patients with chronic conditions. 9
