The Basic Structure of Health Care Systems
A Simple Interaction Between Providers and Patients
Basic Interaction in Healthcare Systems
Participants:
Patients: Individuals seeking care due to illness, injury, preventive needs, or information.
Healthcare Providers: Professionals and institutions offering care (e.g., doctors, nurses, pharmacists, hospitals, imaging centers).
Goal: Facilitate the flow of healthcare services from providers to patients efficiently and timely.
Healthcare Flow:
Care for the sick and injured.
Preventive care for healthy individuals.
Information and answers to health-related questions.
Compensation:
Necessary for the sustainability of healthcare provision.
Ensures providers remain incentivized to offer services.
2. Traditional Healthcare Systems
Structure: Simple transaction-based interaction between patients and providers.
Historical Context:
This model prevailed globally for much of recorded history.
Even in the late 1800s and early 1900s, many regions followed this basic system.
3. Transition to Modern Healthcare Systems

Technology and Data: Use of electronic health records, telemedicine, and data analytics to enhance care quality and efficiency.
The Problem of Risk
1. Simple Transaction Model
Participants:
Patients: Seek health care for sickness, injury, preventive care, information, or concerns for others.
Healthcare Providers: Deliver care; includes doctors, nurses, pharmacists, lab technicians, hospitals, imaging centers, etc.
Basic Structure:
Healthcare Services: Provided to patients in return for compensation.
Historical Context: This simple transaction model worked effectively for a long time, allowing people to access and pay for healthcare services.
2. Factors Leading to Change
Improvement in Medical Care:
Historical Advances:
Mid 1800s: Limited efficacy of medical services; some treatments were ineffective or harmful.
Late 1800s to mid 1900s: Significant medical advancements.
Germ Theory of Disease: Understanding infectious diseases.

3. Emergence of Financial Issues
Unplanned Medical Expenses:
Patients faced large, often unexpected medical bills.
Difficulty in paying bills led to hesitation in seeking future care, undermining the healthcare system's purpose.
Provider Challenges:
Non-payment for services rendered impacted the financial stability of healthcare providers.
Threatened the long-term sustainability of healthcare services.
4. Introduction of Risk in Healthcare
Definition of Risk:
Possibility of facing financial loss associated with the use of healthcare.
Particularly focuses on unpredictable, random, and significant financial losses.
Importance of Risk:
Patient Perspective: Risk of incurring unplanned, large medical bills affects their willingness to seek care.
Provider Perspective: Risk of non-payment impacts their ability to provide care sustainably.
Prevalence of Risk:
Unpredictable nature of healthcare needs makes financial planning challenging.
Sophisticated and costly healthcare increases the likelihood of unaffordable situations for patients.
5. Breakdown of the Simple Transaction Model
Reason for Breakdown:
The significant and unpredictable risk associated with modern healthcare made the simple transaction model unviable.
Healthcare could no longer be treated as a simple good or service due to the financial risks involved.
Need for New Solutions:
Addressing risk became essential for maintaining the functionality and sustainability of healthcare systems.
Led to the development of more complex healthcare financing and delivery systems.
6. Conclusion:
Evolution from Simple to Modern Systems:
Initial simple transaction model was disrupted by the advent of significant medical advancements and the introduction of financial risk.
Modern healthcare systems had to evolve to manage these risks and ensure the sustainable delivery of care.
Solving the Problem of Risk: Risk Pooling
The Problem of Risk
Simple Transaction Breakdown:
Healthcare transactions between patients and providers become untenable due to financial risk.
Unpredictable and high costs can make it difficult for patients to afford necessary care.
Example Scenario:
1,000 people with varied healthcare needs:
1% chance of needing $100,000 worth of care.
29% chance of needing $15,000 worth of care.
60% chance of needing $1,000 worth of care.
10% chance of needing no care.
Risk makes high healthcare costs unmanageable for individuals.
2. Solution: Risk Pooling
Concept of Risk Pooling:
Pooling risk means sharing financial risks among a large group.
Each individual contributes to a collective pool that covers the group's medical expenses.
This reduces individual risk and makes costs more predictable and manageable.
Mathematical Illustration:
Expected costs for 1,000 people:
$100,000 for 10 people (1%) = $1,000,000.
$15,000 for 290 people (29%) = $4,350,000.
$1,000 for 600 people (60%) = $600,000.
$0 for 100 people (10%) = $0.
Total expected cost = $5,950,000.
Dividing evenly among 1,000 people = $5,950 each.
3. Impact of Risk Pooling
For Individuals:
Eliminates the risk of facing extremely high medical bills.
Replaces unpredictable costs with a fixed, manageable amount ($5,950 in this example).
For the Group:
Shares the burden of healthcare costs.
Reduces financial uncertainty for each member.
4. Definition and Importance
Risk Pooling:
The spreading of financial risks across a large number of contributors to a pool.
Reduces the level of risk facing any one person by combining risks across multiple people.
Risk Redistribution:
Shifts risk from individuals to the group.
The group is collectively better positioned to handle financial risks.
5. Challenges and Considerations
Uneven Contribution Shares:
Not all contributions might be equal; considerations for fairness and equity.
Variable Health Events:
Unexpected events (e.g., bad flu season) can affect overall healthcare costs.
Diverse Health Status:
Healthier individuals might not want to be in the same pool as less healthy individuals.
Important to ensure broad participation for effective risk pooling.
6. Conclusion:
Risk Pooling in Modern Healthcare:
Essential to address the problem of financial risk in healthcare.
Systems are designed to pool risk, making healthcare costs more predictable and manageable for everyone.
Future Topics:
Methods of implementing risk pooling in modern healthcare systems.
Insurance and Intermediaries for Risk Pooling
1. The Problem of Risk:
Background:
Simple transactions between patients and providers are untenable due to financial risk.
Unpredictable high costs can make it difficult for patients to afford necessary care.
2. Risk Pooling:
Concept:
Risk pooling involves sharing financial risks among a large group to reduce individual risk.
Involves collecting funds from a group and using them to cover healthcare costs for members.
3. Intermediaries:
Definition:
Entities that collect funds from a group, pool them, and pay for healthcare.
Also known as private insurance companies, insurers, payers, or health plans.
Types of Intermediaries:
Private Insurance Companies:
Sell health insurance policies (contracts to pay medical bills under certain conditions).
Collect premiums from enrollees, pool them, and use them to pay healthcare costs.
Examples: Blue Cross Blue Shield, Aetna, Kaiser.
Government Programs (Public Intermediaries):
Cover healthcare costs for a group of people.
Collect funds through taxes, premiums, or other payments.
Use the collected funds to pay healthcare bills, removing risk from individuals.
4. Process:
Private Insurance Companies:
Sell policies to a large group, collect premiums, and create a pooled fund.
Use the pooled fund to pay medical bills for covered members, thereby pooling risk.
Government Programs:
Collect funds from the population through taxes or premiums.
Use the collected funds to pay healthcare costs, pooling risk and removing it from individuals.
5. Modified Healthcare System Structure:
Population:
Pays money through premiums (private insurance) or taxes/fees (government programs).
Intermediaries:
Pool risk and pay healthcare providers for patient care.
Providers:
Receive payments from intermediaries for providing care.
Out-of-Pocket Payments:
Patients still make some payments directly to providers, known as out-of-pocket payments, user charges, or cost-sharing.
6. Conclusion:
Role of Intermediaries:
Essential in modern healthcare systems for effective risk pooling.
Facilitate the flow of funds and reduce individual financial risk by pooling it across a large group.
Reflection Exercise
The two general kinds of intermediaries that do risk-pooling in the US healthcare system are:
Private Insurance Companies: These are private entities that sell health insurance policies to individuals and groups. They collect premiums from their members and use these funds to pay for healthcare services covered under the policies.
Government Programs (Public Intermediaries): These are government-run programs that provide health coverage to specific groups of people. They are funded through taxes and other government revenues and use these funds to pay for healthcare services.
The importance difference between them is funding source:
Private Insurance Companies: Funded primarily through premiums paid by individuals or employers who purchase health insurance policies.
Government Programs: Funded through taxes and other government revenues, meaning the cost is distributed across the broader tax-paying population rather than just those enrolled in the program.
Insurance companies and government/government programs. Insurance companies sell insurance policies to their enrollees, who pay the insurance company a premium to be covered under that policy. Governments collect funds, either through the tax system or via a premium system, and use those funds to cover the health costs for a group of people.
Beyond Patients, Providers, and Intermediaries: Other Players in the Health Care System
Governments in Healthcare Systems:
Direct involvement in providing care, such as hiring physicians or operating hospitals.
Regulatory roles including oversight of intermediaries and healthcare providers.
Setting licensing requirements for healthcare professionals and facilities.
Other Companies in Healthcare:
Development, manufacturing, and sale of drugs and medical devices.
Service providers offering data and computer systems for managing health records (e.g., electronic health records).
Companies developing applications for patient health management.
Additional Entities in Healthcare Systems:
Professional societies and medical associations supporting healthcare providers.
Public health organizations addressing population health issues.
Philanthropic organizations providing or financing healthcare for underserved populations.
Overview of the Types and Roles of Intermediaries
Managed Care and Intermediaries:
Intermediaries not only pool risk but also manage the care that their members receive.
Managed care strategies vary among intermediaries, influencing healthcare outcomes and costs.
Examples include HMOs (Health Maintenance Organizations), PPOs (Preferred Provider Organizations), and high deductible health plans.
Variety and Complexity of Intermediaries:
Intermediaries operate in diverse combinations across different healthcare systems globally.
No single country typically relies on a single intermediary to cover all its population.
Different intermediaries may serve specific demographics (e.g., Medicare for those over 65 in the US) or geographic areas.
Countries like the UK combine a public intermediary (NHS) covering all residents with options for private insurance.
Overview of the Types and Roles of Providers
Kinds of Providers in Healthcare:
Medical Professionals:
Physicians (Doctors):
Specialize in various medical fields (e.g., internists, pediatricians, cardiologists).
Work in outpatient settings (clinics, offices) or inpatient settings (hospitals).
Supporting Medical Professionals:
Nurses: Essential in providing care, often working collaboratively with physicians.
Nurse Practitioners and Physician Assistants: Play roles in patient care under physician supervision.
Technologists and Specialists: Conduct medical procedures (e.g., drawing blood, operating imaging equipment).
Other Medical Professionals:
Optometrists, Midwives, Pharmacists, Dentists, Therapists, Emergency Medical Providers: Provide specialized care in their respective fields.
Organizations Providing Care:
Physician Practices:
Provide administrative and physical infrastructure for outpatient care.
