Racial and ethnic differences in delivery of tobacco-cessation services.

Background: Reducing racial and ethnic disparities in health care is an important national goal. Racial and ethnic differences in the delivery of tobacco-cessation services were examined in the course of visits to primary care physicians. Methods: In 2007, data about tobacco screening were analyzed from 29,470 visits by adult patients to 2153 physicians in the 2001-2005 National Ambulatory Medical Care Survey, a cross-sectional survey. Counseling was examined for visits by patients with known current tobacco use. Logistic regression models included age, gender, visit diagnoses, expected payment source, and past-year visits to the provider. Results: The respective percentages of visits with tobacco screening and counseling were 79.2% and 28.8% for non-Hispanic white patients, 79.3% and 29.2% for non-Hispanic black patients, 80.2% and 30.6% for non-Hispanic Asian patients, and 68.2% and 21.4% for Hispanic patients. In multivariable models, the adjusted difference between Hispanics and non-Hispanic whites in the percentage of visits with screening was -7.9 (95% CI=-15.5, -0.3) and of visits with counseling was -7.6 (95% CI=-15.2, 0.0). Conclusions: Tobacco screening and counseling were less common at visits made by Hispanics compared to non-Hispanic whites. Traditional barriers to care among Hispanic patients, Such as lack of insurance and more new-patient visits, did not explain the observed differences.
