Health Care Use and Health Care‒Amenable Mortality Among US Adults With and Without a Bachelor's Degree, 1996‒2023.

Objectives. To describe health care‒related educational divides in 2 dimensions-outpatient care utilization and medically preventable deaths-over the past 25 years. Methods. We examined education-based disparities in ambulatory care utilization by analyzing data on 476 277 respondents aged 25 years or older to the 1996-2022 US Medical Expenditure Panel Survey, and in deaths potentially preventable by medical care (defined by International Classification of Diseases, 10th Revision, code) from 26 092 720 death certificates of individuals aged 25 to 74 years in the United States from 2001 to 2023. Results. In 1996, the share of adults with zero provider visits was higher among those without (26.4%; 95% confidence interval CI = 25.3, 27.5) than with (20.2%; 95% CI = 18.5, 22.0) a bachelor's degree, a gap that widened to a nearly 2-fold difference by 2022; the gap in the proportion with no doctor visit also widened. Disparities in health care use were larger after adjustment for health factors. Separately, we observed large and growing education-based gaps in age-adjusted health care‒amenable mortality. Conclusions. Education-based disparities in ambulatory health care utilization have grown since 1996, as have medically preventable deaths. Public Health Implications. Improved health care access for less-educated Americans might help address widening disparities in ambulatory health care use and, potentially, health outcomes. (Am J Public Health.
