Which of the following is NOT one of the four main components of health care delivery systems?

The correct choice indicates that "Global financing" is not one of the four main components of health care delivery systems. The four primary components typically recognized in health care delivery systems include service delivery, health workforce, governance, and financing.

Service delivery is essential as it encompasses the provision of health care services to patients, ensuring they receive the necessary care. The health workforce refers to the health professionals who deliver these services, such as doctors, nurses, and support staff, highlighting the importance of having a skilled team to provide care efficiently. Governance involves the frameworks and processes that guide health systems, including policies and regulations that ensure accountability and proper functioning of health care services, while financing pertains to the funding mechanisms that support these health systems.

While global financing might play a role in the broader context of health care systems, particularly in international health and development, it does not represent one of the core components that constitute the functioning of health care delivery systems at a national or local level.
