Abstract:
A prospective study was conducted to evaluate tuberculosis treatment outcomes according to socio-economic status (SES) using different classification criteria. Patients aged ≥18 years under treatment for ≤8 weeks were interviewed. Outcomes were classified as successful (cure/completed) or unsuccessful (default/failure/death). The overall treatment default ratio was 20.9% and the unsuccessful outcome rate was 24.1%. Unsuccessful treatment was associated with SES according to any criteria used, except for the definition of poverty line. Poverty seems to be hampering the achievement of the World Health Organization targeted 90% cure rate in developing settings.
