This study examines catastrophic health expenditures and the potential for such payments to impoverish South African households. The analysis applies three different catastrophic expenditure measurements, and we apply them across four South African Income and Expenditure Surveys. Since households have limited resources, they are also limited in their capacity to purchase health care. Thus, if a household devotes a large share of that capacity to health care, it may not be able to cover other necessary expenses, which could be catastrophic. The measurements differ in their definition of household capacity. Despite the differences in measurements, and, therefore, results, we find limited incidence of health care expenditure catastrophe, although larger shares of capacity are being devoted to health care in more recent years. In line with the finding that catastrophe is rare, we find that very few households are subsequently impoverished, because of health care costs.

This study estimates progressivity of out-of-pocket (OOP) health payments and their determinants using South African Income and Expenditure Surveys. Concentration is decomposed to examine the effect of household determinants on OOP inequality, shedding light on how progressivity/regressivity is related to changes in the concentration and elasticities of the determinants over time. Our results suggest that actual OOP health expenditures are concentrated among non-poor households, although less so now than in the recent past. When OOP health payments are viewed from the perspective of affordability, which instead focuses on the share of payments relative to capacity-to-pay, they are regressive; However, they have become less concentrated amongst poor households, although still regressive, recently. These results appear to be independent of the measure of socioeconomic status employed in the analysis. The results highlight large income and education related disparities and also suggest continued gender and ethnic differences that deserve further attention in policymaking.
