epidemiology

1.Define the terms disease cluster, outbreak, and epidemic and provide an example of each.

2.An experimental study was conducted to evaluate the effectiveness of a new medication for hypertension in hypertensive women aged 40 -55. The cumulative incidence of hypertension in the group receiving the new medication was 10/100 = 10% and the cumulative incidence in the group receiving the standard medication was 30/100 = 30%.
a. Calculate the relative risk.
b. Provide an interpretation of the relative risk.
c. Calculate the attributable risk (absolute difference in cumulative incidence).
d. Provide an interpretation of the attributable risk.

answer for question #2:
Calculate the relative risk .
Relative Risk = New Medication Cumulative Index/ Standard Medication Cumulative Index = 10/30 = 0.33
Provide an interpretation of the relative risk .
A relative risk of 0.33 would mean that those women taking the new drug had of the risk of being hypertensive compared to those in the study that were taking the standard medication .
Calculate the attributable risk absolute difference in cumulative incidence . Attributable Risk = New Medication Cumulative Index – Standard Medication Cumulative Index = 10 % – 30 % = -20 %
Provide an interpretation of the attributable risk .
An attributable risk of -20 % would mean that 20 patients out of 100 patients would not have had hypertension had they taken the new drug instead of the standard medication .
