The socio-economic impact of TB may plunge households into financial catastrophes. The End TB strategy seeks to mitigate socio-economic factors which may act as barriers to accessing TB services. Countries have been encouraged to provide baseline estimates of catastrophic costs by 2020. We sought to determine the prevalence, risk factors and major drivers of catastrophic costs among TB patients in Zimbabwe. Methods: We conducted a nationally representative, health facility-based survey with random cluster sampling among TB patients. We enrolled patients with drug susceptible (DS-TB) and drug resistant TB (DR-TB) consecutively. We administered a standardised questionnaire to capture the costs incurred as well as lost income due to TB illness. Catastrophic costs were measured at a threshold of 20%. We did a sensitivity analysis of indirect costs using the time lost by patients in each phase of treatment. We us...

Currently, there is insufficient information about treatment delays in Zimbabwe, and we therefore determined the extent of patient and health systems delays and their associated factors in patients with microbiologically confirmed PTB.
