Factors Associated With All-Cause Mortality Among Patients With Multidrug-Resistant Tuberculosis-United States, 1993-2013.


We assessed characteristics associated with all-cause mortality among US patients with multidrug-resistant tuberculosis. Mortality decreased from 31% during 1993-2002 to 11% during 2003-2013. Directly observed therapy coverage increased from 74% to 95% and was protective against all-cause mortality after accounting for demographics, clinical characteristics, human immunodeficiency virus status, and period of treatment.
