Abstract

Background: Healthcare reform in the United States has focused on improving the value of health care, but there are some concerns about the inequitable delivery of value-based care.
Objective: We examine whether the receipt of high- and low-value care differs by education levels.
Methods: We employed a repeated cross-sectional study design using data from the 2010–2019 Medical Expenditure Panel Survey. Our outcomes included 8 high-value services across 3 categories and 9 low-value services across 3 categories. Our primary independent variable was education level: (i) no degree, (ii) high school diploma, and (iii) college graduate. We conducted a linear probability model while adjusting for individual-level characteristics and estimated the adjusted values of the outcomes for each education group.
Results: In almost all services, the use of high-value care was greater among more educated adults than less educated adults. Compared to those with no degree, those with a college degree were significantly more likely to receive all high-value services except for HbA1c measurement, ranging from blood pressure measurement (4.5 percentage points [95% CI: 3.9–5.1]) to colorectal cancer screening (15.6 percentage points [95% CI: 13.9–17.3]). However, there were no consistent patterns of the use of low-value care by education levels.
Conclusion: Our findings suggest that more educated adults were more likely to receive high-value cancer screening, high-value diagnostic and preventive testing, and high-value diabetes care than less educated adults. These findings highlight the importance of implementing tailored policies to address education-based inequities in the delivery of high-value services in the United States.
