NUR 608 Module 2 Worksheet
Each question below is valued at 10% of the total grade of 100 for the Worksheet. (The worksheet is 5% of the total course grade).
1. A. Explain the difference between morbidity and mortality.
B. Provide a clear example of each.
2. What does the case fatality rate of a disease tell us about the disease?
3. A. Explain the difference between incidence and prevalence of a disease.
B. Provide a clear example of each.
Case:
• The population of a coal mining community mid-year was 9,800.
• The number of new cases of lung cancer in this community between January 1 and June 30 (mid-year) = 80.
• The total number of cases of lung cancer as per the cancer registry in this community as of June 30 = 354.
• The annual mortality rate in this community is 12.3 per 1000 (higher than the national average).
• 55 people in this community died of lung cancer this year.
Questions 4-10 are based on the case presented above. Show all work for calculations including formulas used. These are found in the power point presentation this week.
4. Calculate the incidence rate (per 1000) of lung cancer in this community for the 6- month period.
5. Calculate the prevalence rate of lung cancer per 1000 for this community June 30.
6. Calculate the actual number of people in the community expected to die this year.
7. Calculate the disease specific mortality rate in this community for lung cancer.
8. Calculate the case fatality rate in percentage for lung cancer in this community.
9. Interpretations:
a. Can one safely say that working in the coal mine causes lung cancer?
b. What other variables may be a factor for those with lung disease?
c. What do the statistics you have calculated tell you?
d. What other information might be helpful in determining who in this community may be at risk for lung cancer?
