# Table 1 List of variables, and their definitions, used in the analysis of Catastrophic Health Expenditure and Healthcare Foregone

#VariableDefinitionRelated Questions/ Database itemsConnection with other measures:CalculationSource
1OOP Health ExpenditureAll OOP health expenditure in last 12 monthsQ10, 11, 15, 16, 20, 22 (section D)CHE numeratorSum of Q10, 11, 15, 16, 20, 22[15]
2Total Consumption ExpenditureFood and non-food consumption per household in last 12 monthsWorksheet HH consumption, item hhtexpCHE denominatorNo calculation, taken directly from database
3Non-food consumption expenditureNon-food consumption per household in last 12 monthsWorksheet HH consumption, item nfdtexpCHE denominatorNo calculation, taken directly from database
4Capacity to paySame as non-food consumption expenditure (#3)
5CHE thresholdThreshold beyond which an OOP health expenditure is considered a CHEn/a Arbitrary values taken from literature[31, 32, 41]
6CHE IncidenceHouseholds incurring CHE, out of total householdsn/aOOP health expenditure (numerator), Consumption expenditure (denominator) and threshold1 if #1 divided by #2 or #3 is beyond #5
0 otherwise
[6, 9, 20, 29, 31, 41]
7CHE IntensityAverage OOP health expenditure value beyond CHE threshold (for households incurring CHE)n/aOOP health expenditure (numerator), Consumption expenditure (denominator) and thresholdIf #6 is 1: #1 divided by #2 or #3 minus #5
0 otherwise
8ImpoverishmentHouseholds incurring CHE which were pushed below poverty line by CHEn/aCHE1 if total expenditure minus OOP health expenditure is inferior to household’s poverty line, 0 otherwise[7, 20, 31]
9Poverty lineConsumption expenditure per household assumed to be a minimum living standard (food/non-food)n/aImpoverishmentSum of adult equivalents in household, times poverty line per adult equivalent (L\$65438)[15]
