ObjectivesTo measure Connecticut's Affordable Care Act qualified health plan enrollees' health insurance literacy (HIL) by race, ethnicity, and language preference.Study DesignStatewide landline and cell phone telephonic survey.MethodsGeographically balanced cohort that oversampled black and Hispanic enrollees. Questions tested enrollees' knowledge of basic health insurance terminology and their use. Survey data were supplemented by deidentified administrative data from the state's health insurance exchange.ResultsOverall, subjects answered 62% of 13 questions correctly. The percentages of correct answers were 53% for black enrollees, 50% for Hispanic enrollees, 74% for white enrollees, and 45% for Spanish-speaking enrollees. The differences by race, ethnicity, and language preference were statistically significant. Overall, enrollees with a college education scored higher across all demographic groups, but disparities by race and ethnicity persisted.ConclusionsHealth insurance terminology and use rules confuse consumers, especially racial and ethnic minorities. Differences in HIL may be a previously underrecognized source of healthcare disparities because even minor errors can result in delayed care or unanticipated medical bills. Low HIL can diminish the practical value of health insurance and exacerbate perceptions of health insurance as offering insufficient value for premium price. Additional research on ways to improve HIL and investments in insurance navigation support for black and Hispanic enrollees are needed.
