• The Great Depression and the Rise of Private Insurance (1930s-1950s): The economic crisis spurred innovations. Hospitals, facing financial strain, developed prepaid plans (like the Baylor University Hospital plan, a precursor to Blue Cross) to ensure revenue. During World War II, with wage freezes in place, employers began offering health insurance as a non-wage benefit to attract and retain workers. This solidified employer-sponsored health insurance as the dominant model, further reinforced by tax exemptions for employer-paid premiums.
• Medicare and Medicaid (1960s): This era marked the most substantial expansion of public health insurance:
  • Medicare (1965): A federal social insurance program primarily for individuals aged 65 and older, regardless of income, and later extended to younger people with certain disabilities and End-Stage Renal Disease.
  • Medicaid (1965): A joint federal-state program offering healthcare coverage for low-income individuals and families. Its “welfare” model meant eligibility varied significantly by state and was tied to specific categories (e.g., pregnant women, children, disabled).
  • The Hill-Burton Act (1946), enacted earlier, also played a crucial role by providing federal grants and loans for hospital construction, significantly expanding healthcare infrastructure across the nation.
• Cost Containment and Managed Care (1970s-1990s): Escalating healthcare costs in the 1970s and 80s spurred efforts to control expenditures. The rise of Health Maintenance Organizations (HMOs) and other managed care models aimed to curb costs by establishing provider networks, requiring referrals, emphasizing preventive care, and implementing utilization management.
• The Affordable Care Act (ACA) (2010): A landmark piece of legislation designed to expand health insurance coverage, improve healthcare quality, and reduce costs. Key provisions included:
  • An individual mandate (later repealed by Congress).
  • An optional expansion of Medicaid eligibility for states.
  • Creation of health insurance marketplaces (exchanges) with federal subsidies.
  • Regulations on insurers (e.g., prohibiting denials for pre-existing conditions, requiring coverage of essential health benefits).
  • A greater focus on preventive care and the shift towards value-based payment models.
• Post-ACA Debates (2010s-Present): The ACA remains a central point of political contention, with ongoing efforts to repeal, replace, or reform its provisions. Debates persist over issues such as universal coverage, the viability of single-payer systems, market-based versus government-led solutions, pharmaceutical drug pricing, and the relentless rise of healthcare costs.

2. Structure of U.S. Healthcare Delivery Systems

The U.S. healthcare delivery system is highly decentralized and fragmented, characterized by a complex mix of public, private, for-profit, and non-profit entities.

• Providers:
  • Hospitals: Operated as federal, state, local, private non-profit, or private for-profit entities. They offer a wide range of inpatient, outpatient, and emergency services.
  • Physicians: Predominantly private practitioners, increasingly organized into large group practices or employed directly by hospitals and integrated health systems.
  • Nurses: Constitute the largest healthcare workforce, providing care across all settings including hospitals, clinics, schools, home health, and public health departments.
  • Other Healthcare Professionals: A vast array of allied health professionals (e.g., physical therapists, occupational therapists, pharmacists, dietitians), mental health providers, and dentists.
