Health was heavily influenced by religious beliefs and gaining favor from deities

Religious healers required prayers and sacrifices to achieve health

Ancient Egyptian medical papyri attributed headaches to demons and supernatural forces

Healing in ancient Greece (11th to 12th centuries BCE) involved pilgrimages to temples of deities

Direct worship at the temple of the healing god Asclepius included prayers, sacrifices, and dream-based cures

The rod of Asclepius symbolizes the ancient belief that health was granted by divine beings associated with medicine

Significant shift from supernatural views of health with Hippocrates around the 5th century BCE

Hippocrates known as the "Father of Modern Medicine"

He distinguished Greek medicine from religious beliefs

Helped emphasize the link between environmental and personal cleanliness and disease origins

He proposed that illness resulted from imbalances among four bodily fluids: black bile, yellow bile, phlegm, and blood

Viewed health as a state of bodily equilibrium that could be achieve by medicinal practices

Modern health practices, including those in Eastern medicine, are based on Hippocratic principles of health influenced by environmental and behavioral factors

Scientific advancements in the Roman Empire (1st century BCE - 5th century CE) evolved health

Galen, the prominent Roman physician, built on Hippocratic ideas by linking bodily fluid balance to temperament and personality

Galen advocated for a holistic approach, emphasizing the study of the entire body as architects follow blueprints

This holistic view included mental and emotional well-being

Development of fresh water aqueducts, sewer systems, and public baths marked the first organized effort to promote public health

Roman innovations shifted healthcare focus from individual care to societal health

Discovery of cells (1665)

Discovery of microorganisms (1676)

Discovery of genes (1866)

Identification of chemical and molecular factors maintaining bodily and mental balance

Refinement of Hippocrates' and Galen's early concepts of health

Development of new health definitions with scientific advancements and improved healthcare practices

Emergence of definitions addressing healthcare on a societal level

Prominent inclusion of the World Health Organization (WHO) definition of health in modern discussions

WHO Definition of Health (1948):

• Describes health as "a state of complete physical, mental, and social well-being, not merely the absence of infirmity or disease."

• Marked a shift from focusing solely on physical disease to a broader understanding of health that includes social determinants.

Post-WWII Context:

• Established by the United Nations to promote global health initiatives.

• Aimed at achieving "the highest possible level of health" for everyone.

Groundbreaking Perspective:

• Expanded the concept of health to include psychosocial, behavioral, and environmental factors.

• Emphasized the pursuit of well-being rather than just the absence of disease.

Impact on Society:

• Influenced political, academic, community, and professional organizations to allocate resources for universal well-being.

• Seen as a major advancement in understanding and achieving health.

Criticisms and Challenges:

• Implementation Issues: Difficulty in addressing complex, chronic conditions and resource disparities between developed and developing regions.

• Millennium Development Goals: Targets, including global health initiatives, were not met by the 2015 deadline.

  
  

René Dubos (1959):

• Criticized the idea that health could be achieved solely through technology.

• Defined good health as the condition that best enables an individual to pursue personal and social goals.

Abraham Maslow (1968):

• Proposed that health is related to fulfilling a hierarchy of needs: physical needs, safety, love and belonging, esteem, and self-actualization.

• This framework suggests that health is linked to personal development and the fulfillment of various levels of needs.

PI Ahmed (1977):

• Suggested in Toward a New Definition of Health: Psychosocial Dimensions that health should be understood relative to individual and societal contexts.

• Defined health as a means to fulfill role obligations, rather than an end in itself.

J. Bircher:

• Advocated for updating traditional health definitions due to the global healthcare crisis.

• Proposed defining health as “a dynamic state of well-being,” encompassing physical, mental, and social potential to meet life’s demands based on age, culture, and personal responsibilities.

• Acknowledges that economic factors and value-based care may still pose challenges to this updated definition.

Limitations of Current Healthcare:

• Modern healthcare is constrained more by delivery systems and implementation than by scientific knowledge.

• High costs with relatively low quality outcomes characterize the current healthcare system in the U.S.

Michael Porter’s Observations:

• Noted that the core issue is not a lack of expertise or scientific progress, but the outdated structure of the healthcare delivery system.

• Argued that providers are delivering modern medicine using a 19th-century market-based system.

• Emphasized that competition in the current volume-based system does not translate into patient value.

Value-Based Healthcare:

• Porter advocates for a value-based approach, defining value as health outcomes achieved per dollar spent.

• A value-based system aligns reimbursement, cost, and health outcomes that are meaningful to patients.

Porter’s Six Principles for Value-Based Healthcare:

1. Integrated Practice Units (IPUs)

2. Cost and Outcome Measurement

3. Bundled Payments

4. Integrated Delivery

5. Geographic Expansion

6. Healthcare IT

Transition to Value-Based Care:

• Efforts to control rising costs and improve outcomes include accountable care organizations, medical homes, and bundled care products.

• The U.S. Secretary of Health and Human Services set a goal to tie 50% of Medicare payments to value-based arrangements by 2018.

Role of Various Stakeholders:

• Employers: Some use bundled payment plans for employee care.

• Community Providers: Collaborate with larger hospitals to offer comprehensive services locally.

• Patients: Engage in initiatives like the NIH Precision Medicine Initiative to support a dynamic learning healthcare system.

Proposed New Definition of Health:

• A holistic state of physical, mental, emotional, and social wellness supported by an integrated, technologically advanced healthcare system.

• Emphasizes meeting the full spectrum of a patient’s medical needs, including disease prevention, management of comorbidities, and addressing unique patient circumstances.

Challenges and Considerations:

• Measuring and comparing patient outcomes will be challenging due to varying expectations and the complexity of individual needs.

• The definition of health should be flexible and comprehensive to address the needs of both individuals and populations effectively.
