Abstract

S E T T I N G: Fifty-six public clinics in Limpopo Province, South Africa. O B J E C T I V E: To evaluate the association between tuberculosis (TB) patient costs and poverty as measured by a multidimensional poverty index. D E S I G N: We performed cross-sectional interviews of consecutive patients with TB. TB episode costs were estimated from self-reported income, travel costs, and care-seeking time. Poverty was assessed using the South African Multidimensional Poverty Index (SAMPI) deprivation score (a 12-item household-level index), with higher scores indicating greater poverty. We used multivariable linear regression to adjust for age, sex, human immunodeficiency virus status and travel time. R E S U LT S: Among 323 participants, 108 (33%) were ‘deprived’ (deprivation score .0.33). For each 0.1-unit increase in deprivation score, absolute TB episode costs were 1.11 times greater (95%CI 0.97–1.26). TB episode costs were 1.19 times greater with each quintile of higher deprivation score (95%CI 1.00–1.40), but lower by a factor of 0.54 with each quintile of lower self-reported income (higher poverty, 95%CI 0.46–0.62). C O N C L U S I O N: Individuals experiencing multidimensional poverty and the cost of tuberculosis illness in Limpopo, South Africa faced equal or higher costs of TB than non-impoverished patients. Individuals with lower self-reported income experienced higher costs as a proportion of household income but lower absolute costs. Targeted interventions are needed to reduce the economic burden of TB on patients with multidimensional poverty.
