Case Study 1 
Case Study:
A case study is an account of activity, event or problem which contains a real or hypothetical situation.
It includes complexities you would encounter in workplace.
To learn about a case study we need the following skills:
1. Analyzing a case
2. Ability to apply knowledge
3. Reasoning and
4. Drawing conclusions
According to Kardos and Smith (1979) a good case has the following features:
It is taken from real life (true identities may be concealed).
It consists of many parts and each part usually ends with problems and points for discussion. There may not be a clear cut off point to the situation.
It includes sufficient information for the reader to treat problems and issues.
It is believable for the reader (the case contains the setting, personalities, sequence of events, problems and conflicts)
Incidence rate:
Incidence is a measure of disease.
It allows us to determine a person's probability of being diagnosed with a disease during a given period of time (means: how many times a person is diagnosed with a disease during a given period of time).
Therefore, incidence is the number of newly diagnosed cases of a disease.
An incidence rate is the number of new cases of a disease divided by the number of persons at risk for the disease.
Incidence rate = No. of new cases of a disease/No. of persons at risk for the disease
If, over the course of one year, five women are diagnosed with breast cancer, out of a total female study population of 200 (who do not have breast cancer at the beginning of the study period), then we would say the incidence of breast cancer in this population was 0.025. (or 2,500 per 100,000 women-years of study)
New cases = 5
No. of persons at risk (total female study population) = 200
Incidence rate = 5/200 = 0.025
Prevalence rate:
Prevalence is a measure of disease.
It allows us to determine a person's likelihood of having a disease.
Therefore, the number of prevalent cases is the total number of cases of disease existing in a
