Universal health coverage (UHC) aims to provide health security and universal access to essential care services without financial hardship to individuals, families and communities. UHC enables a transition to more productive and equitable societies and economies and is enshrined in the 2030 Sustainable Development Goals (SDGs). But UHC should not be implemented without considering the quality of the care provided. Quality means care that is effective, safe, people-centered, timely, equitable, integrated and efficient. High-quality care improves health outcomes and reduces waste. It is integral to a high-value, sustainable health system. Universal access to high-quality health care is not a luxury only rich countries can afford. It can be achieved in all settings with strong leadership, planning and implementation. The returns are worth the investment. While significant progress has been made to improve care quality has been made, more effort is needed in both developing and developed countries. This report describes the current situation with regard to UHC and global quality of care, and outlines the steps governments, health services and their workers, together with citizens and patients need to urgently take.
