Overuse and Insurance Plan Type in a Privately Insured Population

Meredith B. Rosenthal, Carrie H. Colla, Nancy E. Morden, Thomas D. Sequist, Alexander J. Mainor, Zhonghe Li & Kevin H. Nguyen
OBJECTIVES: A substantial portion of healthcare spending is wasted on services that do not directly improve patient health and that cause harm in some cases. Features of health insurance coverage, including enrollment in high-deductible health plans (HDHPs) or health maintenance organizations (HMOs), may provide financial and nonfinancial mechanisms to potentially reduce overuse of low-value healthcare services. STUDY DESIGN: Using 2009 to 2013 administrative data from 3 large commercial insurers, we examined patient characteristics and health...

Benjamin A. Y. Cher, Nancy E. Morden & Ellen Meara
RESEARCH DESIGN: We analyzed the 2010-2016 Medicaid State Drug Utilization Data using a difference-in-differences regression approach, comparing prescriptions per enrollee between states that expanded Medicaid in 2014 and states that did not. We compared opioid pain relievers and opioid addiction therapies to 5 other commonly prescribed drug types important to the Medicaid expansion population (antidepressants, antihypertensives, diabetes medications, cholesterol treatments, and contraceptives) and to overall prescription volume. A secondary analysis compared opioid pain relievers and...
