Public Health Approach Flashcards
evidence based public health
development, implementation, and evaluation of effective programs and policies in public health through application of principles of scientific reasoning
Public health approach to solving health problems (questions to ask)
What is the problem
What is the cause
What interventions work
How do you implement interventions
Epidemiology
study of disease distribution & determinants
Fundamental assumptions about human disease
- does not occur at random
- not evenly distributed in populations
- must understand person place and time
Epidemiology connects ____, _____, and _____
Host, Environment, Agent
epidemic
disease occurrence among a population that is in excess of what is expected in a given time and place.
cluster
group of cases in a specific time and place that might be more than expected.
endemic
disease or condition present among a population at all times.
pandemic
disease that spreads across regions
rate
number of cases occurring during a specific period; always dependent on the size of the population during that period.
risk factor
Any attribute, characteristic or exposure of an individual that increases the likelihood of developing a disease or injury.
time sequence
exposure must precede the disease
prevention/control
methods used to eliminate /modify cause decrease disease incidence; altering cause alters the effect
strength of association
exposure more common in diseased individuals
consistency
same variable, factors, or events have same repeated association with disease
biologic gradient
longer exposure to cause=greater likelihood of getting disease
prevention effectiveness
assessment of the
impact of public health policies,
programs, and practices on health
outcomes by determining their
effectiveness, safety, and costs.
impact evaluation
assesses the changes that can be attributed to a
particular intervention, intended and unintended
outcome evaluation
assess the effect of
the intervention on the health issue of interest
cost benefit analysis
evaluates multiple options and compares among sectors
formative
conducted in development or improvement of program
summative
evaluation based on efficacy of program after established
