Population Health Study Guide Questions and
Correct Answers with Rationale Graded A+ |
New Update 2026/2027
1. What percent of the US population has at least one chronic disease? Of the 10
leading causes of death in the US, what percent are preventable? - ANSWERS
50% has one chronic conditions
70% of these causes are preventable
2. T/F: The US spends more on healthcare than any other nation because the US
leads the world on key population health indicators. - ANSWERS False. Us
spends more on healthcare yet ranks poorly on most measures.
Only 1st in in technology
3. What is "population health?" - ANSWERS The health outcomes of a group of
individuals and the distribution of such outcomes within a grouup
4. What are some key differences between the "medical model" of health versus
the "population health" model? Why is understanding the distribution of health
outcomes in a population important? Why is understanding the distribution of
health outcomes in a population important? - ANSWERS The medical Model
-Fee For Service incentivizes volume
-Sickcare system focuses on treatment of individual ill patients
-Focus on individual risk
-Clinical reactive/ (drugs, equipment, dx, maneuvers contribute to health)
,-Healthcare is central to producing health
-Focus on disease
-Fragmented, silo'd duplicative
The Population Health Model
-Value Based Pay rewards quality and incentivizes cost reduction
-healthcare system focuses on coordinated holistic care across continuum
-Focus on social structures
-Comprehensive/proactive/preventitive
-Addressing health's determinants and health disparities are central to producing
health
-Focus on health, wellbeing, Health related quality of life
-Integrated and coordinated
5. What three epidemiological or health eras did Susser and Susser (1996)
describe and what are their basic features? (Era, paradigm, analytical approach,
preventive approach)? - ANSWERS 1. Saniitary statistics[miasma]. Clustering of
morbiditiy and mortality--->introduce draininage sewage and sanitation
2. Infectious DIseases[germ theory]. Laboratory and expirments---> interrupt
transmission through vaccines and quarantines, antibiotics
3. Chronic disease epidemiology[black box]. risk ratios of exposure to outcomes---
> control risk factors by modifying lifestyle
4. eco-epidemiology[chinese boxes]=relations within and between localized
structures organized in a heirarchy of level. analysis of determinants and
outcomes at different levels/contexts.-->apply both information and biomedical
technology to find leverage at efficacious levels
, 6. Can we say with certainty we currently live in one specific era? Why or why
not? - ANSWERS No, because we utilize strategies from all eras.
7. What are some modern examples of preventive strategies proposed by each
era? - ANSWERS 1. Sanitation= We still use sewers and flourinated water
2. Infectious disease= we still use vaccines and antibiotics
3. Chronic Disease= Anti smoking campaign and exercise campaigns
4. Eco-epidemiology= Community engagement linked with social health and policy
development
8. Who is the "Father of Modern Epidemiology" and why? What was the
significance of removing the handle off of the Broad Street pump? - ANSWERS
John Snow. First suspected waterborne transmission. disproved miasma by using
the first natural experiment.
Used clusters of cholera death to show that cities from lower thames were
associated with more death. WITHIN GROUP ANALYSIS
He broke off broad street pump = less deaths
9. In the classic infectious disease transmission model (agent, host, environment),
what elements/attributes/characteristics make up each of these points of
intervention to "cause" illness? - ANSWERS SINGLE CAUSE SINGLE EFFECT
Triad:
1. Host(who)
-intrinsic elements or host factors =susceptibility
2. Agent(what)
-pathogenicity severity genetically
-virulence severity conditionally
