Study on Incentives for Glaucoma Medications Adherence

Glaucoma topical eye medications, when adhered to, are effective at controlling disease progression. Yet evidence shows that many glaucoma patients have incomplete adherence to medications, with disease progression resulting in significant costs to the patient and health system. Through the approach of value pricing, a link can be made between non-adherence and its resulting costs by granting subsidies to adherent patients for their medications and physician visits. This 6-month randomized controlled trial among 100 glaucoma patients from the Singapore National Eye Centre aims to test the extent to which value pricing can improve medication adherence.
