1 of 3

• Single-payer systems involve government-funded healthcare for all citizens (United Kingdom's National Health Service)
• Multi-payer systems feature multiple insurance providers, both public and private (United States)
• Single-payer systems often lead to lower administrative costs and universal coverage
• Multi-payer systems offer more choice but can result in coverage gaps and higher overall costs

Universal vs private insurance

• Universal healthcare systems ensure coverage for all citizens regardless of income or employment status
• Private insurance systems rely on individuals or employers purchasing coverage from private companies
• Universal systems prioritize equity in access to care but may face longer wait times for non-emergency services
• Private insurance systems can offer more personalized options but may leave some individuals uninsured or underinsured

US healthcare system structure

Public programs: Medicare and Medicaid

• Medicare provides health coverage for Americans aged 65 and older, as well as certain younger individuals with disabilities
• Medicaid offers health coverage to eligible low-income adults, children, pregnant women, elderly adults, and people with disabilities
• Both programs are funded through a combination of federal and state taxes
• Medicare consists of different parts (A, B, C, and D) covering various aspects of healthcare

Private insurance market

• Includes individual and family plans purchased directly from insurance companies or through the Health Insurance Marketplace
• Regulated by state and federal laws, including the Affordable Care Act
• Offers a range of plan types (HMOs, PPOs, EPOs) with varying levels of coverage and cost-sharing
• Premiums, deductibles, and out-of-pocket maximums vary widely between plans

Employer-sponsored coverage

• Most common form of health insurance in the United States
• Employers typically share the cost of premiums with employees
• Often offers more comprehensive coverage at lower rates due to group purchasing power
• Subject to regulations such as ERISA (Employee Retirement Income Security Act) and the Affordable Care Act

Healthcare delivery models

Fee-for-service vs value-based care

• Fee-for-service model reimburses providers for each individual service or procedure performed
  • Can lead to overutilization of services and higher costs
• Value-based care focuses on patient outcomes and quality of care rather than quantity of services
  • Aims to improve health outcomes while reducing overall healthcare spending
• Shift towards value-based care represents a significant change in healthcare delivery and payment structures

Managed care organizations

• Include Health Maintenance Organizations (HMOs) and Preferred Provider Organizations (PPOs)
• Aim to control healthcare costs through network restrictions and care coordination
• HMOs typically require referrals for specialist care and have more limited provider networks
• PPOs offer more flexibility in choosing providers but often at higher out-of-pocket costs

Accountable care organizations

• Groups of doctors, hospitals, and other healthcare providers who voluntarily work together to provide coordinated care
• Focus on improving quality of care while reducing unnecessary spending
• Share in financial savings if they meet quality and cost targets set by Medicare or other payers
• Emphasize preventive care and chronic disease management to improve overall population health
