The Fair Financial Contribution Index (FFCI) and catastrophic healthcare expenditures were the indicators used by WHO to calculate equity in household payments to the health system (4).
In Iran, statistics for FFCI range from 83.7% in a national study to 56.0% in a regional study.
the proportion of households facing catastrophic health expenditures, and FFCI were calculated.
The following formula was used to calculate FFCI. The results range from 0 (perfect inequality) to 1 (perfect equality) (1).
When this data was analyzed using the FFCI formula, the index obtained was 0.6 for the study population.
The FFCI and the proportion of the households faced with catastrophic health expenditure are two indicators that can help policy-makers identify the shortcomings of risk contribution and other financial protection mechanisms available in financing systems (1).
