Catastrophic health expenses and impoverishment of households of patients with rheumatoid arthritis.

BACKGROUND: The cost of certain diseases may lead to catastrophic expenses and impoverishment of households without full financial support by the state and other organizations. OBJECTIVE: To determine the socioeconomic impact of the rheumatoid arthritis (RA) cost in the context of catastrophic expenses and impoverishment. PATIENTS AND METHODS: This is a cohort-nested cross-sectional multicenter study on the cost of RA in Mexican households with partial, full, or private health care coverage. Catastrophic expenses referred to health expenses totaling >30% of the total household income. Impoverishment defined those households that could not afford the Mexican basic food basket (BFB). RESULTS: We included 262 patients with a mean monthly household income (US dollars) of $376 (0­18,890.63). In all, 50.8%, 35.5%, and 13.7% of the patients had partial, full, or private health care coverage, respectively. RA annual cost was $ 5534.8 per patient (65% direct cost, 35% indirect). RA cost caused catastrophic expenses in 46.9% of households, which in the logistic regression analysis were significantly associated with the type of health care coverage (OR 2.7, 95%CI 1.6­4.7) and disease duration (OR 1.024, 95%CI 1.002­1.046). Impoverishment occurred in 66.8% of households and was associated with catastrophic expenses (OR 3.6, 95%CI 1.04­14.1), high health assessment questionnaire scores (OR 4.84 95%CI 1.01­23.3), and low socioeconomic level (OR 4.66, 95%CI 1.37­15.87). CONCLUSION: The cost of RA in Mexican households, particularly those lacking full health coverage leads to catastrophic expenses and impoverishment. These findings could be the same in countries with fragmented health care systems.
