Background: As one of the World Health Organization (WHO) End Tuberculosis (TB) Strategy is to reduce the proportion of TB affected families that face catastrophic costs to 0% by 2020. This systematic review and meta-analysis aimed to estimate the pooled proportion of TB affected households who face catastrophic cost. Method: A search of the online database through September 2020 was performed. A total of 5114 articles were found, of which 29 articles got included in quantitative synthesis. Catastrophic cost is defined if total cost related to TB exceeded 20% of annual pre-TB household income. R software was used to estimate the pooled proportion at 95% confidence intervals (CIs) using the fixed/random-effect models. Result: The proportion of patients faced catastrophic cost was 43% (95% CI 34-52, I2= 99%. 32% (95% CI 29 - 35, I2= 70%) among drug sensitive, and 80% (95% CI 74-85, I2=54%) among drug resistant, and 81% (95% CI 78-84%, I2= 0%) among HIV patients. Regarding active versus passive case finding the pooled proportion of catastrophic cost was 12% (95% CI 9-16, I2= 95%) versus 42% (95% CI 35-50, I2= 94%). The pooled proportion of direct cost to the total cost was 45% (95% CI 39-51, I2= 91%). The pooled proportion of patients facing catastrophic health expenditure (CHE) at cut of point of 10% of their yearly income was 45% (95% CI 35-56, I2= 93%) while at 40% of their capacity to pay was 63% (95% CI 40-80, I2= 96%). Conclusion: Despite the ongoing efforts, there is a significant proportion of patients facing catastrophic cost, which represent a main obstacle against TB control.

Background: One of the World Health Organization End Tuberculosis (TB) Strategy is to reduce the proportion of TB affected families facing catastrophic costs (CC) to 0% by 2020. CC is defined if total cost related to TB management exceeded 20% of annual pre-TB household income. This study aimed to estimate the pooled proportion (PP) of TB affected households who suffered from CC. Method: A search of the online database through September 2020 was performed. Of 5114 articles, 29 articles were included in meta-analysis. We used R software to estimate the PP at 95% confidence intervals (CIs) using the fixed/random-effect models. Result: The PP of patients faced CC was 43%. Meta-regression revealed that country, drug sensitivity and HIV co-infection were the main predictors. CC incurred by drug sensitive, drug resistant and HIV coinfection patients were 32%, 80%, and 81% respectively. Lower CC incurred by active than passive case finding; 12% versus 42%. Direct cost represented 55% (95% CI 43-66) of the total cost. About 45% of TB-affected household faced catastrophic health expenditure at cut-off point of 10%. Conclusion: There is still a significant proportion of TB patients facing CC, which represent a main obstacle against TB control.PROSPERO registration: CRD42020221283
