Introduction to Healthcare and Public Health in the US Introduction and History of
Modern Healthcare in the US Lecture a
• Health – often thought of as the absence of disease
• World Health Organization (WHO) - specialized agency of the United Nations definition: Health is defined as the “…state of complete physical, mental and social well-being and not merely the absence of disease or infirmity”
• Thus “illness” is a state of poor health
Healthcare
• Healthcare is the prevention and treatment of illness• Healthcare is delivered by different people from different
disciplines, including– Medicine– Dentistry– Nursing– Laboratory Science– Pharmacy– Other allied health professions
• These people come together as interdisciplinary teams to deliver care

• Healthcare is delivered in different places• Inpatient facilities
– Hospitals• Institutions for treating sick or injured people• Historically places for shelter, almshouses• Hospital Survey and Construction Act (also known
as the Hill-Burton Act) passed in 1946 that provided federal grants to improve hospital physical infrastructure
Healthcare Delivery (continued)
• Inpatient facilities – Different types of hospitals
• General medical and surgical hospitals• Specialty hospitals (orthopedic, pediatrics,

Healthcare Delivery (continued)
• Nursing and residential care facilities– Can be short term facilities or long term
facilities– Long term care classified by level of care– Nursing homes initially proliferated after an
amendment of the Social Security Act and gradually shifted from being part of the welfare system to being a part of the healthcare system

• Nursing and residential care facilities– In 1969, "Intermediary Letter 371" drastically reduced
coverage for nursing homes– In 1970, the Miller Amendment established a new
standard - "intermediate-care” facilities– In the 1990s another standard was defined: “subacute
care” – that provided care for patients discharged from hospitals who briefly need a higher level of care “than is provided to the majority of patients in a skilled nursing facility”.

Healthcare Systems
• A healthcare system is an organization that delivers healthcare
• Many variations and iterations of healthcare systems worldwide, but in general, healthcare systems
– promote good health in populations
– balance the levels of actual care provided with the expectations of the population they serve

Healthcare Systems (continued)
• Different models of healthcare systems– Purely public (care conducted by the state)– Purely private (care conducted by
independent, privately funded organizations)– Often a mixed model
• In countries with state run healthcare system, a private system may coexist in parallel or offer services not available under the public system

Healthcare Systems (continued)
• There is no universal healthcare system in the US
• But there are public and private components • Public healthcare systems may be organized:
– At the federal level (for example, the Veterans Health Administration)
– As a partnership between federal and state governments (such as Medicaid and the Children’s Health Insurance Program)
– At the local level14Health IT Workforce Curriculum
