2. Problem 2 You conduct a randomized controlled trial to evaluate the cost-effectiveness of a policy that improves quality-adjusted life years (QALYs). The effectiveness and costs were measured as the following: Intervention group that Baseline Outcome Measures Follow-up Outcome Policy Measures Costs Quality of Quality of Life- life utility life utility Life-years $ years value value received the policy 0.3 200 0.8 250 $6,000,000 intervention Control group that did not receive the policy 0.3 180 0.4 200 $870,000 intervention a) What is the effectiveness of the policy intervention relative to the control group, in terms of QALYs? b) What is the incremental cost-effectiveness ratio of this policy intervention in terms of cost per QALY? c) Using the US threshold of incremental cost-effectiveness ratio, would you recommend this policy or not
