Shelby is a 32-year-old mother of two, who has
smoked 1 pack-per-day for the last 15 years, and who comes to see you today for
her yearly well-woman exam in your family practice clinic. She has a family
history, in a single paternal grandmother of breast cancer at age 52. She also
has a history of an abnormal cervical cancer screening three years ago
requiring colposcopy.
Given her history please consider the
following:
Choose one screening test that might be
considered either now or in the next few years of Shelby’s care. Define the
test, its positive predictive value, reliability and validity.

definition, description, signs and symptoms, and current incidence and/or
prevalence statistics current state, local, and national statistics pertaining
to the disease. (Include a table of incidence or prevalence rates by your
geographic county, state, and national statistics.)

and any mandated reporting or methods for reporting the disease for providers.
4. Conduct descriptive epidemiology analysis
of the disease including who is more frequently affected and characteristics of
the population that might help in creating a prevention plan. Include costs
(both financial and social) associated with the disease or problem.
5. Review how the disease is diagnosed,
current national standards for screening or prevention, and pick one screening
test and review its sensitivity, specificity, positive predictive value, cost
and any current national guidelines for conducting which patients to conduct
this test on.
