This chapter examines how the Swiss health system performs in terms of health achievements, prevention, and quality of health services. While the Swiss health system is relatively expensive, it delivers high health outcomes and inequalities in health are less pronounced than in most other OECD countries. However, in the field of health promotion and disease prevention, outcomes are mixed and opportunities to improve health are not currently being taken. A lack of clear designation of responsibilities in the Swiss system and incentives to invest in prevention activities are key reasons for this. Finally, while quality is recognised as an important issue, mechanisms for monitoring and managing health-care quality seem weak and make it difficult to have an overall view of the quality of the Swiss health-care system.
