True or False: Health communications are how we perceive, combine and use health
informatics to make decisions. - Answer true
True or false: You should trust every online source for health informatics. - Answer
False
Which source of population health data is useful to alert to new diseases or potential
spreads of disease beyond initial areas? - Answer Single case or small series
Which source of population health data includes birth, death, marriage, divorce and
reporting of key communicable and specially-selected non-communicable diseases? -
Answer Vital Statistics
Which source of population health data is useful to draw conclusions about overall
population and subgroups from representative samples? - Answer Surveys
Which study involves a group of individuals who meet inclusion criteria followed
prospectively in time for risk factor and outcome information? - Answer Prospective
cohort study
Which study has the advantage that it is cost and time efficient for rare outcomes? -
Answer Case-control study
Which population health measure is the health standard describing the rate of death in
the first year of life: - Answer Infant mortality rate
Which population health measure is the health standard describing the probability of
dying at each year of life: - Answer Life expectancy
True or false: Incidence is the number of existing cases, and prevalence is the number
of new cases. - Answer False
What is the gold standard for study design? - Answer Randomized Control Trial
Prevalence is the number of new cases and incidence is the number of existing cases. -
Answer False
When a variable can contain any value between a theoretical minimum and maximum,
the variable type is: - Answer Continuous
, Which statistic is a standard that tells us how many standard deviations above or below
the population mean a raw score, or observation we have made, is from the mean? -
Answer z-score
Which significance value below describes that you are 99.9% certain that your observed
value did not happen by chance alone? - Answer p-value<.001
True or false: A confidence interval is significant if the value of 1 is not found in the
interval. - Answer True
When you are comparing two categorical variables to each other, you use the: - Answer
Chi-square statistic
When we want to measure how two different variables are associated with, or change
with each other, we can examine their: - Answer Correlation
True or false: We use multiple linear regression for dichotomous outcomes - Answer
False
True or false: We use logistic regression for continuous outcomes - Answer False
True or false: A confounder variable is related to the risk factor and also to the outcome.
- Answer True
True or false: In simple linear regression with a single independent variable, the
coefficient tells you how much the dependent variable is expected to increase (if the
coefficient is positive) or decrease (if the coefficient is negative) when that independent
variable increases by one. - Answer True
True or false: The Evidence-Based Care Model provides components that help
clinicians reach the "triple aim" of healthcare, and improve patient satisfaction and
quality of care, while simultaneously reducing costs. - Answer True
True or false: To achieve higher quality healthcare while simultaneously reducing costs,
health systems must move towards an evidence-based model. - Answer True
The Principles of Clinical Practice include: - Answer Access, clinical decision support,
risk stratification, patient engagement, accountability, measuring and improving over
time
Which Principle of Clinical Practice says healthcare providers should have improved
access to data and knowledge through improved technology such as electronic medical
records? - Answer Access
