• “Health” & Its Determinants
• Health Systems & Healthcare Systems
• Functions & Components
• Characteristics of a Desirable Health System
• Models of Healthcare Systems
• Thailand’s Context
• Major Issues in Health Care

6. Health
• Health vs. Illness and Disease
• Medical Model:
Health = Absence of Illness or Disease
• So what’s the problem with this model?
6
7. Problems with the Medical Model
• Emphasis on treatment of illness/disease
• Promotion and Prevention deemphasized
• Not true sense of the word “Health” but
rather just “Lack of ill health”
• So what’s a better model of health?
Shi & Singh (2004)

8. The WHO Model & Definition
• “Health is a state of complete physical,
mental and social well-being and not
merely the absence of disease or infirmity.”
WHO Constitution (1948)
• Also known as biopsychosocial model of
health
8
9. Holistic Health
• The well-being of every aspect of what
makes a person whole and complete

Social Determinants of Health
• The circumstances in which people are
born, grow up, live, work and age, and the
systems put in place to deal with illness.
These circumstances are in turn shaped by
a wider set of forces: economics, social
policies, and politics.
14
WHO (2008)
17. Health Systems
• A health system consists of all
organizations, people and actions whose
primary intent is to promote, restore or
maintain health.
• Includes efforts to influence determinants of
health as well as more direct health-
improving activities.
• More than the pyramid of publicly owned
facilities that deliver personal health
services. WHO (2007)
17
18. Health Systems
• Includes
• A mother caring for a sick child at home
• Private providers
• Behavior change program
• Vector-control campaigns
• Health insurance organizations
• Occupational health and safety legislation.
• Inter-sectoral action by health staff, for
example, encouraging the ministry of education
to promote female education, a well known
determinant of better health. WHO (2007)
18
19. Health Care
• Health care: Activities and services
performed to improve a person’s health and
well-being, through prevention and
treatment of illness.
• Similar terms
• Healthcare services
• Healthcare delivery
Adapted from Shi & Singh (2004)
19
20. 20
Healthcare Systems
• An organization that delivers healthcare
• In general, healthcare systems
• promote good health in populations
• balance levels of actual care provided
with the expectations of the population
they serve
• Narrower definition than WHO’s “Health
Systems”

National Coordinator for Health Information Technology, U.S. Department of Health and Human
Services (Health IT Workforce Curriculum v.3.0/Spring 2012, Component 1/Unit 1a).
21. 21
Healthcare Systems
• 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

22. 22
Healthcare Systems
• Privately owned, commercial organizations
may also act as healthcare systems
• These organizations may serve a single area
or multiple geographic locations
• Private healthcare systems may be:
• Not-for-profit organizations (governed by
principle of non-distribution) or
• For profit organizations (distribute surplus
funds to shareholders or owners)

23. 23
Healthcare Systems
• Healthcare systems can be measured
using benchmarks
• One framework for assessment:
•Patient assessed value
•Performance on clinical interventions
•Efficiency

Public Health
24
“is the science and art of preventing disease, prolonging life
and promoting health through the organized efforts and
informed choices of society, organizations, public and
private, communities and individuals.“
(Winslow, C.E.A. 1920)

25. What is Public Health?
• Private Health
• Clinicians, Health
Practitioners
• Treat Individual Health
Problems
• Action usually taken after
illness/injury occurs
• Public Health
• Agencies
• Treat/Maintain Health of
Populations
• Actions include
Education, Policy,
Research, Monitoring

How Has Public Health Improved
Healthcare?
• Improvements in understanding disease
• Epidemiology is considered the basic science of public
health and is
• a quantitative basic science
• a method of causal reasoning based on developing
and testing hypotheses pertaining to occurrence and
prevention of morbidity and mortality
• a tool for public health action to promote and protect
the public’s health

29. 29
• An example of epidemiology at work:
• In 1854: epidemic of cholera in London, England
• Cholera is a bacterial disease
• Lack of sanitation and overcrowding led to the spread
of disease
• Dr. John Snow linked the spread of disease to a
contaminated public water pump
• Snow’s hypothesis: cholera was spread by
contaminated water

Summary
• Health Health care
• There are “Health” issues beyond hospitals
• There are key players of “Health” beyond
hospitals
• Clinicians should learn to play collaborative
roles with others within and outside hospitals
for health of individuals and population.
