Examining the Impact of State-Mandated Insurance Benefits and Reimbursement Provisions on Access to Diabetes Self-Management Education and Training (DSME/T)

Abstract

With an estimated 30.2 million diagnosed and undiagnosed cases among adults (and another 84 million at risk), diabetes mellitus is one of the most prevalent chronic conditions and a leading cause of mortality in the US. Diabetes self-management education and training (DSME/T) is a recognized standard of care and provides patients with the requisite knowledge and skills to properly manage the condition, improve long-term health outcomes, and reduce health care expenditures. Yet, DSME/T is greatly underutilized. Health insurance coverage that does not include benefits for DSME/T effectively imposes barriers to access for patients in need of the service. Many states have adopted laws and regulations requiring public and/or private insurers in their market to provide benefits for DSME/T; however, these requirements vary by state. It is unclear if these policies effectively improve access to DSME/T services. This dissertation seeks to rigorously assess the impact of state-mandated benefits and reimbursement provisions on access to DSME/T among adult patients with diabetes. The first analysis utilizes a unique combination of legal and programmatic data to quantify changes in the supply of DSME/T resources after the adoption of state-mandated benefits (potential access). The second analysis merges legal data with the Medical Expenditure Panel Survey (MEPS) from 2008 to 2016 to examine the impact of state mandates and reimbursement provisions on patient utilization of DSME/T (realized access). Lastly, the final analysis utilizes electronic health record data (2010-2016) from a safety net population to determine if patients’ evaluated need for DSME/T predicts the likelihood of receiving a DSME/T referral during a provider encounter (equitable access). Using novel data sources and a sophisticated policy analysis technique, this study provides a rigorous assessment of the impact of decades of state policies designed to improve access to care.
