Determinants of catastrophic healthcare expenditure in Peru.

The aims of this study were to assess factors associated with catastrophic healthcare expenditure (CHE) and the burden of out-of-pocket (OOP) payments for specific healthcare services in Peru. We used data from 30,966 households that participated in the 2016 National Household Survey (Encuesta Nacional de Hogares, ENAHO). Participants reported household characteristics and expenditure on ten healthcare services. CHE was defined as healthcare spending equal to or higher than 40% of the household's capacity to pay. The associations of various household characteristics and OOP payments for specific healthcare services with CHE were assessed in logistic regression models. Poorer, rural and smaller households as well as those with older adults and individuals with chronic conditions had greater odds of facing CHE. According to the estimates from the adjusted regression model, healthcare services could be grouped into three groups. Medical tests, surgery and medication were in the first group with odds ratios (ORs) between 6.43 and 4.72. Hospitalisation, outpatient, dental and eye care were in the second group with ORs between 2.61 and 1.46. Child care, maternity care and other healthcare services (such as contraceptives, rehabilitation, etc.) were in the third group with non-significant ORs. Many Peruvian households are forced to finance their healthcare through OOP payments, burdening their finances to the extent of affecting their living standards.
