Imagine that there are two cohorts of 100 patients each. One group got the flu vaccine and other group did not.

Outcomes

Vaccine Group Outcomes = 90 patients without the flu

No-Vaccine Group Outcomes = 50 without the flu

Costs

Vaccine Group Costs = $100 per vaccination; $200 healthcare costs per case of flu

No-Vaccine Group Cost = $200 health care costs per case of flu

Calculate the average cost of the alternative vaccine.

I said $120

Calculate the average cost of the alternative no-vaccine:

I said $100

According to the results of the evaluation, the average cost of vaccine is higher than the average cost of no-vaccine.

I said true

Estimate the cost-effectiveness ratio (C/E) of the alternative vaccine:

I don't know how to do this??

a. $40

b. $200

c. $400

d. None of the above

Estimate the cost-effectiveness ratio (C/E) of the alternative no-vaccine:

I don't know this one either

a. $40

b. $200

c. $400

d. None of the above

Estimate the incremental cost-effectiveness of no-vaccine vs. vaccine

a. $50

b. $300

c. $700

d. None of the above

According to the results of the evaluation we can affirm that the no-vaccine alternative would save money in comparison with the vaccine alternative:

Question 7 answers

a. True

b. False

According to the results of the evaluation we can affirm that the vaccine alternative would save money in comparison with the no-vaccine alternative:

a. True

b. False

According to the results of the evaluation we can affirm that the vaccine alternative has better outcomes:

a. True

b. False

Given the information available in this evaluation, if the cost of vaccine and no-vaccine were the same, the cost-effectiveness of both alternatives would be the same:

Question 10 answers

a. True

b. False
