Interviews were conducted among 109 completers and 20 non-completers (12 physician- and 8 patient-initiated). Completers were motivated by fear of TB (44%), understanding the importance of IPT (32%) and counseling (22%). Patient-initiated non-completers were dissuaded by stigma (58%), side effects (14%) and travel distance (1%). HIV-infected subjects provided with counse...Continue Reading
