When all people and communities can use the promotive, preventive, curative, rehabilitative, and palliative health services they need, of sufficient quality to be effective, while also ensuring that the use of these services does not expose the user to financial hardship.

This definition comprises three related objectives:
1. Equity in access to health services. Everyone who needs services should get them, not only those who can pay for them.
2.The quality of health services should be good enough to improve the health of those receiving services.
3. People should be protected against financial risk by ensuring that the cost of using services does not put people at risk of financial harm.
