Which of the following statements are correct?
a. Case fatality rate is more useful in chronic than in acute diseases.
b. Case fatality rate is more useful in acute than in chronic diseases.
c. 5-year survival and improvements in screening are unrelated.
d. An improvement in screening can lead to improved 5-year survival rates.
e. An improvement in screening can lead to a decline of 5-year survival rates.
f. An improvement in 5-year survival rates always means that treatment for the disease has improved.
Answer: B & D
Explanation:
B is correct because case fatality rates are better in acute than chronic diseases. When someone with an acute disease dies, it’s more likely that their death was due to the acute disease. Conversely, when someone with a chronic disease dies, it could well be that their death was due to some other problem. Chronic diseases often have very long durations during which other things can happen that are unrelated to the chronic disease itself. That’s why case fatality rates are more useful in acute diseases.
D is also correct because improving screening could lead to earlier detection of a disease, thereby improving 5-year survival without changing the course of the disease.
The other answers relating to screening are wrong.
