25% of diabetics skimp on insulin because of cost – Cardiovascular Business

As insulin prices in the U.S. continue to surge, lower-income diabetics are struggling to afford a drug their life depends on, researchers report in a JAMA Internal Medicine study published Dec. 3.

The study, authored by Darby Herkert, BS, and colleagues at the Yale School of Medicine, involved surveying 199 patients about the affordability of their medication and the likelihood that they’d skimp on insulin to cut costs. Subjects were 51 percent female, 61 percent white and 42 percent type 1 diabetics, and Herkert’s team considered insulin “underuse” as taking less insulin than prescribed, trying to “stretch out” insulin doses, failing to fill insulin prescriptions or stopping use altogether due to cost.

Of the diabetics surveyed, more than 25 percent admitted they’d compromised their insulin regimen to save money—a result that generated considerable buzz after Herkert et al. initially presented their findings at the American Diabetes Association’s annual conference in June. While patients’ type of prescription drug coverage wasn’t linked to underuse, a lower income was.

Nearly 40 percent of lower-income patients said they hadn’t discussed the cost of insulin with their clinician, and 15 percent changed insulin type due to prices. In multivariable analysis, participants who reported cost-related insulin underuse were more likely to have poor glycemic control (43.1 percent compared to 28.1 percent of regular-use patients).
