Step-by-step explanation:
Public hospitals in the United States represent about 25% of all healthcare facilities and can be referred to as Governmental Hospitals. These institutions are a crucial part of the healthcare system, serving the public and often providing care for those who may not have insurance or the means to afford private healthcare. While universal healthcare is not present in the United States, government-funded insurance programs like Medicare and Medicaid extend support to specific groups such as the elderly, poor, and disabled. Moreover, the Veterans Health Administration is an example of a socialized medicine system within the U.S., where the government owns and operates the healthcare facilities.
