This document discusses patient payment policies in Europe. It summarizes that while most European countries have formal cost-sharing arrangements like co-payments and deductibles, informal payments also exist. Formal and informal payments seem to operate independently. Patient cost-sharing policies aim to improve efficiency, contain costs, and generate revenue for healthcare. While arrangements vary across countries, the most common types are co-payments for visits to general practitioners and coinsurance for hospitals. Exemptions from cost-sharing are common for low-income, children, and elderly patients.
