Discussion: Disease Screening Evaluation

Prevention
of disease is the major focus of public health. One way to prevent disease is
screening for disease. Disease screening can reduce morbidity and mortality as
well as transmission of the disease to others. However, a lot of research and
costs are associated with disease screening. Are all screening methods created
equal?
You will choose a screening method for a disease (infectious or chronic)
and evaluate it.
Discuss
the following:
1)
Describe the health issue in detail. Who does the health issue affect and what
is the magnitude of the health issue?
2)
Describe the current or proposed screening method for this disease. What is the
biological basis for this screen meaning how does it detect the disease? What
markers are used or what scale is used? What stage in the disease can the
screen be used? Is it a mass screen or selective screening?
3)
Describe the characteristics of the screen. How does it compare to the 5
attributes of a good screening test: simple, rapid, inexpensive, safe, and
acceptable?
4)
Evaluate the screening method. Discuss the reliability, validity, sensitivity,
and specificity or the screen. Give data to support your discussion.
