1. Healthy People 2020 - ANSWER ✓ aims to reach four overarching
goals: 1.Attain high-quality, longer lives free of preventable disease,
disability, injury, and premature death, 2. Achieve health equity,
eliminate disparities, and improve the health of all groups 3.Create
social and physical environments that promote good health for all. 4.
Promote quality of life, healthy development, and healthy behaviors
across all life stages.
2. Determinants of care/health - ANSWER ✓ The range of personal,
social, economic, and environmental factors that influence health status
are known ...
3. risk analysis - ANSWER ✓ the characterization of the potential
adverse health effects of human exposures to environmental hazards
4. health disparities - ANSWER ✓ the difference in health statuses
between various groups (populations).
,5. Sensitivity - ANSWER ✓ measures the proportion of actual positives
that are correctly identified as such (e.g., the percentage of sick people
who are correctly identified as having the condition)
6. Specificity - ANSWER ✓ (also called the true negative rate)
measures the proportion of actual negatives that are correctly identified
as such (e.g., the percentage of healthy people who are correctly
identified as not having the condition)
7. Positive predictive value - ANSWER ✓ is the probability that
subjects with a positive screening test truly have the disease
8. epidemiological triangle - ANSWER ✓ 1. A traditional model of
infectious disease causation, known as the Epidemiologic Triad is
depicted in Figure 2. The triad consists of an external agent, a host and
an environment in which host and agent are brought together, causing
the disease to occur in the host.
9. confounding variable - ANSWER ✓ is an "extra" variable that you
didn't account for. They can ruin an experiment and give you useless
results. They can suggest there is correlation when in fact there isn't.
They can even introduce bias. That's why it's important to know what
one is, and how to avoid getting them into your experiment in the first
place
10. Study Methods - ANSWER ✓ descriptive and analytic
,11. descriptive study - ANSWER ✓ describes person place and time.
Provided data for program planning, resource planning, and generates a
hypothesis. Types include correlational studies, case reports and studies,
and cross-sectional studies.
12. analytic study - ANSWER ✓ consists of observational and
experimental. Observational include case control and cohort.
Experimental includes random control trial (typically for new drug
testing), field trial (conducted on those who have a high risk of obtained
a disease), and community trial (research is conducted on an entire
community or neighborhood). Test a hypothesis.
13. Rapid Cycle Improvement (RCI) - ANSWER ✓ 1. "quality
improvement method that identifies, implements and measures changes
made to improve a process or a system." it implies that changes are
made and tested over periods of three or months or less, rather than the
standard eight to twelve months. It consists of fours stages:
Plan: Identify an opportunity to improve and plan a change or test of
how something works.
Do: Carry out the plan on a small number of patients. The test period
may be as short as one day for small PDSA cycles.
Study:Examine the results. Did you achieve your goals?
Act: Use your results to make a decision, incorporate changes into your
workflow, and establish future quality improvement plans
14. Is screening a tertiary intervention? If yes, why, if not, what is it? -
ANSWER ✓ No, it is secondary.
, 15. How does a provider determine the usefulness, appropriateness, of a
screening test? Where would and NP look to find a screening test? What
determines if a screening test should be used? - ANSWER ✓
Determining whether a screening test is appropriate requires the APRN
to address several aspects of the disease of interest. The target
population needs to be identifiable. There should be enough people to
make the study cost effective. The preclinical period should be proficient
to allow treatment before symptoms appear so that early diagnosis and
treatment make a difference in terms of outcomes. The NP could look at
the U.S. Preventative Services Task Force, Agency for Healthcare
Research and Quality, and SAMHSA-HRSA to find a screening test.
Sensitivity and specificity measure the validity of a test. Sensitivity is
the number identified/ the number affected. Specificity is the number
identified in the screening of not having the disease/ the actual number
who do not have the disease.
16. Can you explain what "descriptive epidemiology" means? What is
the purpose? How is it used? - ANSWER ✓ It covers time place and
person.
First, by looking at the data carefully, the epidemiologist becomes very
familiar with the data. He or she can see what the data can or cannot
reveal based on the variables available, its limitations (for example, the
number of records with missing information for each important
variable), and its eccentricities (for example, all cases range in age from
2 months to 6 years, plus one 17-year-old.).
Second, the epidemiologist learns the extent and pattern of the public
health problem being investigated — which months, which
neighborhoods, and which groups of people have the most and least
cases.
