A cancer registry in another state is described in a published paper as a passive surveillance
system. What is a major limitation of this type of cancer registry? -
Answer✅
Incomplete reporting
Quiz_________________?
A crude mortality rate (measure) -
Answer✅
Is a summary rate for the total population
Is influenced by population characteristics
Is an unadjusted measure of the risk of dying in the population for a given time period
Quiz_________________?
A program manager from an international health funding agency needs to identify regions
that would benefit from an intervention aimed at reducing premature disability. The
program manager asks a health care consultant to develop a proposal using an index that
would help her make this decision. Which of the following would best serve this purpose?
1
, a. case-fatality
b. crude mortality rate
c. disability-adjusted life-years
d. standardized mortality ratio -
Answer✅
c. disability-adjusted life-years
Quiz_________________?
Active surveillance system -
Answer✅
Reports are solicited from reporting sources at established intervals
Examples: call labs every Monday for disease report or calls initiated as part of an
epidemiological investigation to rapidly detect additional cases
Strengths: rapid, increased sensitivity and specificity, may increase collection of appropriate
specimens, increases specimen submission to PH Lab for specialized typing or ID
Limitations: Resource intensive, difficult to maintain for extended periods of time
Quiz_________________?
Adjusted measures -
Answer✅
Summary measures for total population statistically transformed to remove the effect of
differences in population composition (such as age)
Allows fair comparisons
Quiz_________________?
Adjusted rates -
2
, Answer✅
Advantages: differences in the adjusted factors between populations removed; permits
unbiased comparison relative to adjusted factor
Disadvantages: artificial rate, does not represent risk of dying, absolute magnitude
dependent on standard population chosen
Quiz_________________?

Potato salad 2.50
Chicken 0.59 -
Answer✅

Quiz_________________?

Quiz_________________?
