2: Epidemiology and Biostatistics to Inform Advanced Practice Nursing
TD1:
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
Upon the course of your history you find out that Shelby has a great aunt on her mother’s side who died of ‘some woman cancer in her stomach’ and an uncle on her father’s side who died of pancreatic cancer. Her mother and older sisters are all in good health.

Epidemiological Formulas and Statistics
Parameter Definition Formula
Incidence (exposed) Incidence of new cases of disease in persons who were exposed number (exposed with disease)/Total number of exposed
Incidence (unexposed) Incidence of new cases of disease in persons who were not exposed number (unexposed with disease)/Total number of unexposed
Incidence of Disease Measure of risk. Total number in a population with a disease divided by the total number of the population. Number with the disease/ Total population number
Relative Risk Risk of disease in one group versus another. Risk of developing a disease after exposure. If this number is one, it means there is no risk. R(exposed)/Risk (unexposed) (# exposed with disease(divided by)/total of all exposed)
(# of non-exposed with disease/(divided by)total of all non exposed)
Odds Ratio A measure of exposure and disease outcome commonly used in case control studies. R(exposed) / R (unexposed)
1- R(exposed) 1-R(unexposed)
Prevalence The number of cases of a disease in a given time regardless of when it began. (new and old cases) (Persons with the disease/ Total population) X 1000
Attributable Risk The difference in disease in those exposed and unexposed and is calculated from prospective data. Directly attributed to exposure (if exposure gone, disease would be gone) R(exposed) – R(unexposed)
Crude Birth Rate The number of live births per 1,000 people in the population (# of births/estimated mid-year population) X 1000
Crude Death Rate The number of deaths per 1,000 people in the population (# of deaths/estimated mid-year population) X 1000
Fetal Death Rate The number of fetal deaths (20 weeks or more gestation) per 1,000 live births. (# of fetal deaths/ # of live births + fetal deaths) X 1000
Annual Mortality Rate Usually an expression of a specific disease or can be all causes per 1,000 people for a year. (# of deaths of all causes (or a specific disease)/Mid-year population) X 1000
Case Fatality Rate The parentage of individuals who have a specific disease and die within a specific time after diagnosis. (# of persons dying from a disease after diagnosis or set period/ # of persons with the disease) X 100
Relative Risk Calculation Worksheet Answer Key

(# of deaths of all causes (or a specific disease)/Mid-year population) X 1000
25,000/2.5 million (0.01) x 1000=10
4. What was the cause-specific mortality rate from malaria? (please show your work)
(# of deaths of all causes (or a specific disease)/Mid-year population) X 1000
5. What was the case-fatality percent from malaria?
(# of persons dying from a disease after diagnosis or set period/ # of persons with the disease) X 100
6. Fill in and total the 4 X 4 table for the following disease parameters:
Total number of people with lung cancer in a given population = 120
Total number of people with lung cancer who smoked = 90
Total number of people with lung cancer who did not smoke = 30
Total number of people who smoked = 150
Total number of people in the population = 350
Fill in the missing parameters based on the above.
7. From Question 6, what is the total number of people with no lung cancer?

2. Background of the disease including 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.)
3. A review of current surveillance methods 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.
6. Provide a brief plan of how you will address this epidemiological disease in your practice once you are finished with school. Provide three actions you will take along with how you will measure outcomes of your actions.
7. Conclude in a clear manner with a brief overview of key points of the entire disease,
