Define Health
WHO’s Definition: A state of physical, mental, and social well-being, and not merely the absence of disease or infirmity.
Differentiate between disease and illness.
Disease: an objective, biological phenomenon characterized by abnormal functioning of the body. A state of being that a health care worker finds.
Illness: a subjective, psychosocial phenomenon in which people perceive themselves as sick. A state of being that the ill person feels.
Medical Model of Health
- Biomedical model
- Focuses on individual’s and on the factors most immediately linked to the pathophysiology underlying a person’s disease.
- Health is defined as the absence of illness or disease.
- Emphasizes diagnosis and treatment.
- Health care is generally reactive.
Population Health Model
- Seeks to explain and intervene in the causes of the systematic differences in health between groups.
- Analyses the patterns or distributions of health between different groups of people in order to identify and understand the factors leading to poorer outcomes.
5 determinants of Health
- Genetic/Hereditary
- Behavior and lifestyle
- Physical environment
- Social environment
- Medical Care
Medical Health Model
- Checks family history
- Lab tests
- Intervention
- Treatment recommendations
The medical model does not ask why an epidemic of obesity has occurred or investigate why there are higher rates of obesity in low income and minority populations.
Population Health Model
Identifies a wide variety of causes over time to produce the epidemic and the differing patterns for obesity among population groups.
1. More fast food restaurants in low-income neighborhoods.
2. Vending machines in schools
3. Decrease in physical education
4. Fewer children and adults walking or biking
Interventions could include health framework, interventions could include zoning law changes, working with fast food restaurants.
Market Justice Health Care
Proposes that market forces in a free economy can best achieve a fair distribution of health care.
Assumptions of Market Justice
- Health care is like any other good or economic service.
- People can make rational choices in their decisions to purchase health care products and services.
- People, in consultation with their doctors, know what is best for themselves.
- The marketplace works best with minimum interference from the government.
Implications of Market Justice
- In a pure market system, individuals without sufficient income or who are insured face a financial barrier to obtaining health care
- Emphasizes individual rather than collective responsibility for health
- Proposes private rather than the government solutions to the social problems of health
Social Justice Health Care
Equitable distribution of health care is a societal responsibility. The government takes over the production and distribution functions. Health care is a social good opposed to an economic good. Canadians and Europeans have social justice.
Assumptions of Social Justice
- Health care is different from most other goods and services.
- Responsibility for health is shared.
- Society has an obligation for the collective good.
- Government, rather than the market, can better decide through rational planning how much health care to produce and how to distribute.
Implications of Social Justice
- Everyone is entitled to a basic package of benefits.
- Public solutions to social problems.
- Planned rationing of health care. Government controls medical technology will be dispersed and who will be allowed access to that technology.
What are 3 quantification perspectives on health and health care that may be used for understanding the nature and health status of the population.
- Demographics and Socio-economic characteristics-census
- Health Status Measures-morbidity, mortality, infant mortality, and life expectancy.
- Health services and resource utilization- who uses the services and what kind of services are offered.
List 2 purposes of quantifying the demographic and socio-economic characteristics, health status indicators and health utilization patterns of the population.
- Descriptions- numbers and characteristics of population being served.
- Program Planning- descriptive data can reveal existence of problems, data can be used to design solutions, and to enable objective evaluation after new programs are implemented.
Crude Death Rate
- Mortality rate
- Influenced by distribution of ages in population.
- Can be misleading
Age-adjusted Rate
These control for changing age distribution of population.
Cause-Specific Mortality
-Rankings based on absolute numbers of deaths
Infant Mortality
Calculated as: # of deaths <1 year age among children born alive divided by the number of live births.
2 Infant Death Categories
- neonatal deaths: < 28 days old (2/3 of infant deaths are neonatal)
- postneonatal deaths: 28 days to 1 year
Trends of Infant Mortality
In the United States, infant mortality rates have decreased from 1960 to 2016. Globally, at the United States has the highest infant mortality rate compared to other countries.
Life Expectancy
- Age to which the average individual can be expected to live, given that the person has reached a specific age.
- Often used as a measure of health for a population
- Improvements in life expectancy are due to advances in science and public health in conquering diseases and reduction in infant mortality.
Incidence
Number of new cases of the disease in question occurring during a specified time period, usually a year.
Prevalence
Total number of cases existing in a population during a specified time period, or at one point in time.
Explain why utilization of health care services data may be incomplete.
Reliable utilization data is regularly reported only for services provided by licensed MD’s, DO’s and dentists. Not for alternative therapy providers. Can be difficult to aggregate all data sources across the country.
What was the role of pharmacist’s in the 1600s.
Physicians had the dual role of diagnosing and treating a patient’s illness. Pharmacist’s are not really a thing.
What was the role of pharmacist’s role in the 1700s.
Emergence of apothecary shops. The role of the shops was to manufacture and distribute medications. Provided “medicine chests” to physicians.
When did the professions of medicine and pharmacy separate, and the independent pharmacy practitioner emerged.
After the War of 1812
Drugstore Era
(1850-1910)
Pharmacists became known as the proprietor of a drugstore.
Pharmacists role- Computing prescriptions, recommending and selling over-the-counter medications and first aid items.
Food, Drug and Cosmetic Act (1938)
This act was responsible for the creation of the Food and Drug Administration (FDA). They are a federal agency that are responsible for approving new drugs for market. Enforced safety and efficacy.
Pharmacists role- dispense medications and counsel patients
