Promoting Engagement in the Drug Resistant TB/HIV Care Continuum in South Africa

Overview

The goals of this research are to understand adherence and retention in care for multi-and extensively drug-resistant tuberculosis (M/XDR-TB) patients using a mixed methods approach.

Tuberculosis (TB) remains the leading cause of morbidity and mortality worldwide among people living with HIV. Globally, incidence of multidrug-resistant tuberculosis (MDR-TB) and extensively drug resistant tuberculosis (XDR-TB), the most drug-resistant forms of TB, has approximately doubled over the past fifteen years. Nowhere has this increased incidence generated more concern than in South Africa where interactions between TB and generalized HIV epidemics are causing 'explosive' TB incidence and case-fatality threatening to undermine the progress reached with antiretroviral therapy (ART). Medication adherence, a key predictor of outcomes in multi-and extensively drug-resistant tuberculosis (M/XDR-TB) and HIV treatment, is understudied in high burden TB/HIV settings. Patient losses during transitions in the care continuum are frequent, increase mortality and limit control of the linked epidemics. Demands of M/XDR-TB HIV treatment are severe including extraordinary pill burden, severe adverse effects, lengthy treatment, isolation and stigma with few parallels in modern medicine. This is a prospective observational cohort study for patients newly diagnosed with M/XDR-TB initiating treatment. A mixed method approach will be employed to address the complex research questions of distilling determinants of barriers and facilitators to both TB medications and ART; this study will employ complementary qualitative and quantitative methodologies for assessing differential adherence to TB medications and ART. A sub-set of patients and health care workers will be approached for participation in focus group discussions.
