CO28 Impact of Value-Based Insurance Design on Medication Adherence in Patients with Asthma and/or COPD in an Employee Health Plan: An Interrupted Time Series Analysis

Abstract

Value-Based Insurance Design (VBID) is intended to incentivize the use of services that are most cost-effective for patient care. One strategy is to reduce patient cost-sharing of medications that are crucial for chronic disease, such as inhalers for asthma and/or chronic obstructive pulmonary disease (COPD). Recently, several benefit changes have been introduced into an employee health plan for a large health system in Texas, including co-pay reductions, deductible elimination, and income-based premium subsidies. This study evaluated the impact of these interventions.
