A paradoxical situation in regressivity or progressivity of out of pocket payment for health care: which one is a matter of the health policy maker's decision to intervention?

Even if the OOP is progressive and the share of poor people is low, this may financially limit their access to health services, increase their risk of incurring catastrophic health expenditure (CHE), and even pushing them more into poverty. In order to provide a comprehensive picture of equity in health financing, other financial protection indicators such as the redistributive effect, re-rating, exposure to CHE, and impoverishment due to health expenditure should also be estimated and reviewed.
