Catastrophic healthcare expenditure – Drivers and protection: The Portuguese case

The objective of this paper is to assess the extent of catastrophic healthcare expenditure, which can lead to impoverishment, even in a country with a National Health Service, such as Portugal. The level of catastrophic healthcare expenditure will be identified before the determinants of these catastrophic payments are analyzed. Afterwards, the effects of existing exemptions to copayments in health care use will be tested and the relationship between catastrophe and impoverishment will be discussed. Catastrophe is calculated from the Portuguese Household Budget Surveys of 2000 and 2005, and then analyzed using logistic regression models.
