Notes: The Role and Organization of Health Care Systems
The Role and Organization of Health Care Systems – Study Notes
Source context: Global overview of health care systems, their organization, funding models, and historical reforms (Beveridge, Bismarck, Private Insurance).
Purpose: Understand how health systems are structured, funded, delivered, and evaluated; connect to current challenges and reforms.
Health: Systemic Goals and Vital Functions
National priority: The health of the people is a national priority; health systems provide promotive, protective, preventive, diagnostic, curative, and rehabilitative services across the lifespan.
WHO goals for national health systems: three overarching goals –
Good health
Responsiveness to population expectations
Fairness of financial contribution
Four vital functions (to achieve the goals):
Service provision
Resource generation
Financing
Stewardship (governance and regulation)
Progress varies by country and over time; performance is assessed by how well these functions are carried out and by outcomes such as access, equity, coverage, efficiency, and financing quality.
Minimum equitable requirements for health care systems (access and quality):
Access to quality services for acute and chronic needs
Effective health promotion and disease prevention
Ability to respond to new threats (emerging infectious diseases, aging populations, non-communicable diseases, injuries, environmental health effects)
Global spending context: health systems are among the largest, most complex, and costly sectors in the world economy.
Global health care spending ≈ of world GDP in the early 21st century.
OECD context (2010 data): U.S. health care costs ≈ of GDP or about per person; OECD country average ≈ per person.
What is a Health System? Boundaries and Components
Health system definition (WHO): all organizations, institutions, and resources devoted to producing health actions.
Health action: any effort (personal health care, public health services, or intersectoral initiatives) whose primary purpose is to improve health.
Health care delivery involves organized efforts (public or private) to guarantee, provide, finance, and promote health.
Boundaries and inclusions:
Includes promotive, protective, preventive, diagnostic, curative, rehabilitative measures.
Includes traditional public health activities, health promotion, and disease prevention across sectors (e.g., road safety, environmental health).
Excludes activities whose primary purpose is education or health benefits that are indirect; however, health-related education is included if health is a direct objective.
Health sector, intersectoral action, and multisectoral action:
Health sector includes government ministries, social security and health insurance, private providers, and NGOs.
Intersectoral action: collaboration between health and other sectors to achieve common health goals.
Multisectoral action emphasizes the contribution of several sectors (similar to intersectoral, with emphasis on multiple sectors).
Global expenditure context (repeat): health systems are costly and centralized around dissemination of health services, including preventive and curative care.
Funding Models: Three Main National Health Care System Designs
Based on funding source and state involvement, three principal models exist:
Beveridge model (public funding via taxation)
Bismarck model (compulsory insurance with employer/employee premiums)
Private insurance model (market-based, with private providers)
Beveridge model (e.g., UK, Ireland, Nordic countries, Canada, Australia, parts of Europe and others):
Funding: taxation; universal access based on residency; services provided mostly by public providers under strong government control.
Features: universal coverage, comprehensive basic benefits, strong Ministry of Health controls; risk of bureaucracy and underfunding.
Bismarck model (e.g., Germany, Netherlands, France, Belgium, Austria, Switzerland, Japan, some CSEE/FSU regions):
Funding: compulsory health insurance with premiums paid by employers and employees; funded through social/mandatory insurance.
Features: mix of public and private providers; intermediate state regulation; efficiency and cost sharing; consumer protections.
Free-market private insurance model (e.g., USA):
Funding: private insurance; public programs for poor/elderly (e.g., Medicare/Medicaid in some cases).
Features: health care treated as a commodity; greater private sector autonomy; weaker or more fragmented state controls; managed care prevalent in many settings.
Important caveat: All three models exist as pyre-types with many mixed forms; no single model is universally best or most efficient.
What shapes systems beyond funding: underlying societal norms and values (solidarity vs. market-oriented perspectives) and political structures influence system design and performance.
Key philosophical implications:
Solidarity vs. market-based approaches: cross-subsidization and universal access vs. competition and consumer choice.
The balance between equity, quality, and cost containment.
The transition from centralized planning to decentralization and market mechanisms in many regions.
Levels of Organization and Delivery: Four Levels of Care
Health care systems operate across four levels of care, structured to match disease complexity and resource intensity:
1) Self care (community level): nonprofessional care within families or small groups; includes health-promoting behaviors, prevention, self-diagnosis, self-treatment, and peer support. Emphasizes empowerment and community responsibility for health. WHO recognizes potential of traditional and alternative medicine as part of self-care strategy.
2) Primary professional care (the first contact): ambulatory settings delivered by general practitioners (GPs) or family doctors, nurses, and allied health professionals; gatekeeper role – GP coordinates care and refers to higher levels as needed; population base typically 2,000 to 50,000 per primary care facility depending on local organization.
3) Secondary or general specialist care (district/provincial level): general specialists (surgeons, internists, gynecologists, psychiatrists, etc.) who provide more complex care via district/provincial hospitals; referral from primary care; population base roughly 100,000 to 500,000.
4) Tertiary or central level (sub-specialist care): highly specialized care delivered in regional or national centers (university hospitals, university clinics), with population bases from 500,000 to 5,000,000; patients may be referred from primary or secondary levels.Administrative units and population size examples (from Chart 1):
Self care: 1–10 people (household level)
Local community health stations/centers: regional population sizes ~2,000–50,000
District/Regional level (secondary care): ~100,000–500,000
Regional/national level (tertiary care): ~500,000–5,000,000
Key care concepts:
Gatekeeper: primary physicians manage access to higher levels of care and determine necessity of specialist referrals.
Primary health care is the central function and main vehicle for delivering health care, serving as the peripheral level and connecting to higher levels.
Planning secondary/tertiary facilities within a regionalized system supports efficient use of expensive technologies and specialized personnel.
Outpatient Care and Primary Health Care
Outpatient care: first contact with professional health care; services delivered without hospital admission; can occur in hospitals, health centers, polyclinics, or private offices.
Historical role of outpatient care:
Origin traces to post-16th century transitions from hospital-centric care to outpatient services (general practitioners, early clinics).
1911 Act in Great Britain formalized general practitioners as primary outpatient providers; later developments cemented GP gatekeeping and outpatient networks.
Alma-Ata Declaration (1978) and primary health care (PHC):
Core principles: universal access on the basis of need; health equity; community participation; intersectoral approach; essential services integrated with public health measures.
PHC is the central function of health systems, the most peripheral level extended to communities, and a key vehicle for social and economic development.
Health centers and outpatient institutions:
Health centers integrated preventive and curative activities, serving defined territorial units, with laboratory/x-ray facilities and multi-disciplinary teams.
Post-Alma-Ata, PHC remained central; health centers became common outpatient institutions; primary care serves as the first contact and ongoing management point.
Home care and substitution policies:
Home care (hospital-at-home) provides examination, diagnostics, treatment, and rehabilitation at home; linked with social protection services and local communities.
Evidence suggests up to ~30% or more hospital-treated patients could be managed at home or via day care with adequate home healthcare support and primary care coordination.
Outpatient services also include consultative-specialist care (intermediary between PHC and hospital care) and home-based or community-based services.
The goal of PHC: ensure universal access, appropriate cost-effective care, and coordination with public health functions (education, immunizations, preventive services).
Inpatient Care and Hospitals
In-patient care: admission to hospitals or stationary institutions for diagnosis, treatment, rehabilitation, with continuous care.
Hospital definitions and types:
General (community or district) hospital: acute care; broad medical/surgical services, obstetrics, pediatrics; can be for either not-for-profit or for-profit.
Special hospitals: focused on a single medical specialty or disease (e.g., pediatrics, maternity, psychiatric, TB, geriatrics, rehabilitation, addiction centers).
University hospitals: education, training, research; often specialized centers providing advanced care.
Hospital bed and capacity concepts:
Hospital bed: bed set up and staffed for in-patient care, located where continuous medical care is provided.
Bed census: regular counting of beds in use; beds per 1000 population is a common metric for comparative planning.
Acute care bed ratio: number of general short-term beds per 1000 population; varies widely across and within countries.
Trends in hospital systems:
Hospitals have grown technologically complex and costly; many systems shift toward more ambulatory and home-based care to reduce inpatient days.
Reforms in some regions (e.g., SEE) have pursued hospital mergers/acquisitions and purchaser-provider splits to improve efficiency and competitiveness.
Hospital organization and management themes:
Mergers and acquisitions as a strategy to increase scale, efficiency, and market power (notably in the USA and parts of Europe).
The interaction between hospital services and community-based care requires changes in management culture toward integration and patient-centered care.
Therapeutic and service mix within hospitals includes:
Diagnosis and treatment, nursing care, and professional services for a broad range of conditions.
Functions of the hospital include prevention/promotion, education/training of health workers, and research (clinical trials, quality assessments).
Day care hospitals: provide daytime treatment without overnight stay; include day treatment programs, day care centers, and transitional day hospitals.
Key Concepts: Health System Boundaries, Resources, and Organization
Core components of health systems:
Health services (promotion, prevention, primary care, specialist medicine, hospital services, targeted services, self-help).
Financing health care (fund mobilization and allocation).
Production of health resources (facility construction/maintenance, medicines, equipment).
Education and training of health personnel (undergraduate and postgraduate).
Research and development (health research, technology transfer, quality control).
National health system management (policy, strategy, information, sector coordination, regulation, manpower planning).
Main objectives commonly cited for national health systems:
Universal access to a broad range of health services
Promotion of national health goals
Improvement of health status indicators
Equity in regional and socio-demographic accessibility and quality of care
Adequacy of financing with cost containment and efficient resource use
Consumer satisfaction and freedom of choice in primary care providers
Provider satisfaction and choice in referral services
Portability of benefits when changing employer or residence
Public administration or regulation
High service quality standards
Comprehensive coverage across primary, secondary, and tertiary levels
Well-developed information and monitoring systems
Ongoing policy and management review
Promotion of education, training, and research standards
Governmental and private provision of services
Decentralized management and community participation
Historical Development and Reforms
Pre-20th century: health systems existed in various forms, often fragmented and charity-based; hospitals were central but not comprehensive systems.
Industrial revolution and social insurance:
1883: Otto von Bismarck enacts a social insurance plan for workers; employer contributions to health coverage begin – first state-mandated social insurance model.
Spread of similar laws in Belgium (1894), Norway (1909), Denmark (1935), Netherlands (later years).
Early state-funded care:
Russia (post-1917 Bolshevik revolution): centralized, state-controlled system offering free medical care for all; maintained for decades.
Post-World War II reforms:
UK’s National Health Service (NHS) established in 1948 following wartime needs and Beveridge framework; universal access and state stewardship became a model influence globally.
Beveridge Report (1942) and White Paper (1944) articulated the principle that everyone should have access to comprehensive, free medical services funded through taxation.
20th century shift toward primary health care and universalism:
1978 Alma-Ata Declaration emphasized PHC as essential to health for all; core principles included universality, equity, community participation, and intersectoral action.
The World Health Organization (WHO) promoted a shift from “all possible care for all” to delivering high-quality essential care that is effective, affordable, and socially acceptable (the “new universalism”).
Global transformation trends (late 20th – early 21st centuries):
Market-oriented reforms, decentralization, reduced state intervention, and expanded private provision in many regions.
Increasing aging populations, rising technology, epidemiological transition toward non-communicable diseases, and expanding health costs drive reform pressures.
Regional reforms and current challenges:
SEE and other regions have pursued hospital consolidation, purchaser-provider splits, and reforms to increase efficiency and access.
New challenges include aging populations, technology-driven costs, rising demand, and the need for stronger community involvement and intersectoral action.
Health System Measurements and Indicators
Coverage and access measures: scope of services, wait times, geographic access, and affordability.
Financial indicators: budgeting efficiency, cost containment, and cross-subsidization to protect vulnerable groups.
Resource generation: workforce density (doctors, nurses), facility availability, and technology adoption.
Performance and equity: fairness of financial contributions, regional disparities, and social justice in health opportunities.
Economic context and global spending:
Global health care spending around of world GDP in the early 2000s.
For the U.S., high per-capita expenditure relative to GDP share compared with other OECD countries.
Practical Implications and Reforms in Practice
Gatekeeping and referrals: PHC acts as the first contact and controls specialist referrals to optimize resource use and maintain cost-efficiency.
Regionalized care planning: planning secondary and tertiary facilities within a population-based framework supports rational use of expensive technologies.
Substitution policies: day care hospitals and robust home-based care networks can reduce unnecessary inpatient stays and costs.
Intersectoral collaboration: achieving health goals requires coordinated action across education, housing, environment, transportation, and social protection sectors.
Equity vs. efficiency: health systems must balance universal access with sustainable financing and high-quality care; policy choices reflect societal values (solidarity vs. market emphasis).
Key Definitions (Concise References)

Health services: The organized set of activities to provide health care, including promotive, preventive, diagnostic, curative, rehabilitative, and palliative services.
Health care organization levels: Self care, primary professional care, secondary/tertiary care, with corresponding administrative units and population scales.
Intersectoral vs multisectoral action: Coordinated actions across sectors to achieve health goals; multisectoral highlights the contribution of multiple sectors.
Primary Health Care (PHC): Essential health care made universally accessible; central to health system performance; aims for universal access, equity, community involvement, and intersectoral collaboration.
Day care hospital: A hospital-based model where patients receive care during the day without overnight stay; includes day treatment programs and transitional day hospitals.
