Impact of the patient-provider relationship on the survival of foreign born outpatients with tuberculosis.
BACKGROUND
Managing tuberculosis in foreign born patients entails a complex interaction between patient and provider.


METHODS
Using a retrospective cohort study and survival analysis, this study evaluates the impact of patient and provider factors on the survival of foreign born outpatients with active tuberculosis. The primary outcome of the study is 1 year all-cause mortality.


RESULTS
In our cohort, patient-provider language discordance was associated with an increased risk of death [HR: 2.33; 95% CI: 1.39-3.88], while receiving treatment from a tuberculosis experienced physician [HR: 0.41; 95% CI: 0.22-0.77] and treatment in a dedicated tuberculosis clinic [HR: 0.53; 95% CI: 0.29-0.98] was associated with a lower risk of death.


CONCLUSIONS
Patient-provider communication and health systems factors played a large role in the survival of our cohort of foreign born tuberculosis outpatients. These findings suggest that language barriers and the provision of care by experienced providers in specialized clinic settings may have important effects on health outcomes.
