Household catastrophic total cost due to tuberculosis in Egypt: incidence, cost drivers and policy implication.

Background: Tuberculosis (TB) is a disease that disproportionately affects the poor. The World Health Organization lists economic factors as one of main barriers to tuberculosis management.

Aims: This study aimed to estimate the household total catastrophic cost of TB and its determinants among newly diagnosed Egyptian tuberculous patients.

Methods: This was a cohort prospective study covering 257 TB patients registered in 2019. The patients were followed up bi-monthly until the end of the treatment regimen (4 visits). A standardized questionnaire published by the poverty sub-working group of the Stop TB Partnership was used after minor modification. The following costs were measured: pre-diagnosis, direct and indirect, guardian and coping, as well as annual household income. Catastrophic cost (direct plus indirect) was considered if the total cost of TB treatment exceeded 20% of the household's annual income. Sensitivity analyses were conducted using different thresholds.

Results: The incidence of household total catastrophic cost was 24.1%. The mean total cost of TB treatment was US$ 198. Over 50% of the total direct cost was incurred during the pre-diagnosis period. After adjustment for other determinant variables using multivariable logistic regression, we found that age < 30 years, living in a house with crowding index > 2, poverty and coping were more likely to cause higher total catastrophic cost.

Conclusions: Catastrophic cost was experienced by 1 out of every 4 new TB patients. As the main cost drivers were poverty and coping, the Ministry of Health and Population should be collaborated with Ministry of Finance and NGOs to put a plan of social protection system for poor families with TB patients.
