Racial Inequality in Inhaler Fills for COPD - A Trial of Reduced Cost-Sharing

"The treatment is proactive outreach that sought to enroll individuals in a VBID program available to all enrollees that provided: 1) large reductions in cost-sharing for maintenance inhalers, and 2) telephone-based COPD medication management services.~Proactive outreach for those randomized to the treatment arm included, at a minimum, a phone call and letter in the mail from Humana. Proactive outreach could also have included an email, text message, and/or provider referral."

Control group participants received no proactive outreach but could call to enroll themselves in the VBID program if they learned about it through traditional means, such as the benefits description manual.
