In a first-of-its-kind research, a cohort of researchers, led by the College of Colorado Anschutz Medical Campus, evaluated the results of state-level insulin out-of-pocket prices throughout states and payers and over time.

The group discovered that state-level caps on insulin out-of-pocket prices don’t considerably improve insulin claims for sufferers with kind 1 or sufferers utilizing insulin to handle kind 2 diabetes. Research outcomes may assist inform insurance policies geared toward higher delivering cost-capped insulin to sufferers fighting insulin affordability.

Roughly one-quarter of sufferers who use insulin to handle diabetes have reported underuse because of the burden of price, a problem state-mandated caps sought to alleviate.
