Catastrophic health expenditure during healthcare financing reform: Evidence from Kazakhstan.

Unequal access to healthcare and inadequate financing have highlighted the need for healthcare reform to increase efficiency while ensuring equity in healthcare financing worldwide. Our study evaluates the capacity of Kazakhstan's healthcare system reform, transitioning from a tax-financed system to compulsory social health insurance (CSHI), to address equity in healthcare financing. Using quarterly Household Budget Surveys from 2017-Q1 to 2020-Q4 in a staggered difference-in-difference estimation technique, we analyze the impact of the transition on the incidence and intensity of catastrophic health expenditure (CHE) and impoverishment.
