  61. What is Geoffrey Rose's big idea?
    "A large number of people who are at low risk [for a disease] may give rise to more cases of disease than the small number who are at a high risk"
  62. An example of Rose's big idea is..
    "Low-risk" patients, "missing the mark" for screened cholesterol levels and then later developing high cholesterol due to being "under the radar"

  70. The traditional and natural medical approach to prevention is..
    The "high-risk" strategy
  71. According to Rose, the 5 advantages to using the high-risk strategy for prevention is..
    • 1) Intervention appropriate to the individual
    • 2) Subject motivation
    • 3) Physician motivation
    • 4) Cost-effective
    • 5) Benefit:Risk ratio favorable

    • According to Rose, the 4 disadvantages to using the high-risk strategy for prevention is..
    • 1) Difficulties and costs of screening
    • 2) Palliative and temporary (Quick fix, takes care of symptoms, but not the actual cause)
    • 3) Limited for the individual and population (gives no real insight to pathology of disease)
    • 4) Behaviorally inappropriate (can't tell people what to eat, do, etc. b/c of societal norms/constructs)
  72. According to Rose, the 3 advantages to using the population-based strategy for prevention is..
    • 1) Radical (Attempts to get rid of underlying cause)
    • 2) Large population for population
    • 3) Behaviorally appropriate (easier to change habits/social norms, because everyone has to change, not just one individual)
  73. According to Rose, the 4 disadvantages to using the population-based strategy for prevention is..
    • 1) Small benefit to individual (prevention paradox)
    • 2) Poor motivation of subject
    • 3) Poor motivation of physician
    • 4) Benefit:Risk ratio is "worrisome"
  74. According to Rose, the population strategy is the attempt to..
    Control the determinants of incidence, to lower the mean level of risk factors, to shift the whole distribution of exposure in a favorable direction.
  75. Rose states the big problem with using the high-risk strategy is that..
    While effective on an individual level, it can not be applied equally to an entire population. In order to effectively "treat" a population, you need to get to and remove the cause of incidence, which can not be done with the high risk strategy
  76. The main conclusion to Rose's paper is..
    High-risk strategy is the best way to find individual susceptibility but fails at a population-scale because it fails to find the cause of incidence which in theory, would be the best way to treat a population, even though the population-based strategy has it's downsides too. The main point though, is that the priority of epidemiology should be to discover and control the causes of incidence
  77. According to Savitz, epidemiology is a _________ and public health is a _________
    • Science
    • Mission
  78. According to Savitz's paper, the definition of public health is
    A mission: The fulfillment of society's interest in assuring the conditions in which people can be healthy: (Improving the health of human populations)
  79. According to Savitz's paper, the substance of public health consists of..
    "organized community efforts aimed at the prevention of disease and promotion of health.
  80. According to the Savitz's paper, the "common" definition of epidemiology is..
    The study of the distribution and determinants of the distribution and determinants of disease frequency in human populations
  81. Why is epidemiology not the basic science of public health?
    Because epidemiology cannot absorb the broader array of scientific and societal concerns that must be considered in the development and implementation of public health policy. Epidemiology is a discipline that draws on other sciences and working research and theories
  82. What is Savitz's main point of explaining the translation of epidemiologic evidence into public health action?
    That epidemiologic information needs to be provided clearly and objectively to public health workers and in order to do that, epidemiologist needs to understand the disciplines involved in their evidence. (if topic is about heart attacks, epidemiologist should know a great deal about anatomy, CVD pathology, etc.)
  83. What is the main conclusion from Savitz's paper?
    Epidemiology is a discipline that requires team work. You need researchers and doctors to pull data, you need an epidemiologist to be able to use their educational background and knowledge to interpret that data and clearly explain it to public health officials so that the officials can make sense of the data and apply the data properly so that public health laws and policies can be implemented. Epidemiology is extremely important, but it is not the basic science of public health, rather than a multifaceted discipline that can be used to aid in the mission of public health.
