The influence of English proficiency on access to care.

OBJECTIVE The number of individuals with limited English proficiency in the USA is large and rapidly growing. Consequently, addressing language barriers in access to medical care is becoming increasingly important. Previous studies have reported that individuals with limited English proficiency have more difficulty gaining access to care, compared to English-proficient individuals. We assessed the impact of English language proficiency on access to medical care, accounting for health and socioeconomic status, using nationally representative data. DESIGN Cross-sectional data from the 2006 National Health Interview Survey (n=29,868). The main outcome measures of interest were self-reported delayed medical care, forgone needed care, and visits to a health care professional. RESULTS In unadjusted analyses, individuals with limited English proficiency were more likely to forgo needed medical care and less likely to have a health care visit, compared to individuals who were proficient in English. There was no significant association between language proficiency and reports of delayed care. After accounting for individuals' health and socioeconomic status, only the relationship between limited English proficiency and health care visits remained statistically significant. Most associations between language proficiency and access to care did not differ across various racial/ethnic groups. CONCLUSION Results indicate that the choice of access measure may influence conclusions about language barriers in health care. Given the growing proportion of US residents with limited English proficiency, health care settings need to better address potential language barriers.
