**Epidemiologic Principles Worksheet Guidelines and Grading Rubric**
**Purpose**
The purpose of this assignment is to help you to begin to understand and apply the important counts, ratios, and statistics presented in healthcare and epidemiological research. Remember to use the list of formulas presented prior to the problems and to carefully consider the purpose of each calculation and how it is interpreted.
**Also, do not forget the importance of the proper denominator such as per 100, per 1,000, per 10,000 etc.**
**Course Outcomes**
· Distinguish the roles and relationships between epidemiology and biostatistics in the prevention of disease and the improvement of health.
· Assimilate principles of epidemiology with scientific data necessary for epidemiologic intervention and draw appropriate inferences from epidemiologic data.
· Utilize appropriate public health terminology and definitions of epidemiology necessary for intra-/interprofessional collaboration in advanced nursing practice.
**Points**
This assignment is worth 50 points.
**Due Date**
Submit your completed worksheet to the Moodle by Saturday of week #3 at midnight Eastern Time
**Requirements**
1. Complete the Risk Calculation Worksheet.

**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 1, it means there is no risk. R(exposed)/Risk (unexposed) | (# exposed with disease[divided by]/total of all exposed) <br>(# of unexposed with disease/[divided by]total of all <br>unexposed) |
| **Odds Ratio** | A measure of exposure and disease outcome commonly used in case control studies | R(exposed) / <br>R (unexposed)<br>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 is 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 midyear population) X 1000 |
| **Crude Death Rate** | The number of deaths per 1,000 people in the population | (# of deaths/estimated midyear 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)/midyear population) X 1000 |
| **Cause Specific Mortality Rate** | Usually an expression of a specific disease per 1,000 people for a year | (# of deaths per a specific disease)/midyear 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 |
**Answer the following questions. Remember that there is only one right answer for each item.**

C. 79 per 100,000 of the population.
D. 130 per 100,000 of the population.

4. What was the cause-specific mortality rate from malaria? (Please show your work.)
5. What was the case-fatality percentage from malaria?
6. Fill in and total the 4 X 4 table for the following disease parameters:
