Determinant factors for adherence to antiretroviral therapy among adult HIV patients at Dessie Referral Hospital, South Wollo, Northeast Ethiopia: a case-control study.

Initiation of antiretroviral therapy at the later stage of the disease and taking anti-tuberculosis concomitantly were negatively associated with adherence. Being on antiretroviral therapy for a longer duration has a positive association. Health facilities and professionals should strictly apply strategies for the prevention of tuberculosis among HIV patients to avoid concomitant use of anti-tuberculosis medications.
