 This narrower usage would apply to the British National Health Service hospital trusts and health systems that operate in other countries as diverse as Finland, Spain, Israel, and Cuba.The United States Veterans Health Administration and the medical departments of the U.S. Army, Navy, and Air Force, would also fall under this narrow definition.When used in that way, the narrow definition permits a clear distinction from single payer health insurance systems, in which the government finances health care but is not involved in care delivery.
