Assignment
A. Compare and contrast the following types of economic evaluation, and provide an example of each: A) Cost of illness studies; B) Cost identification; C) Cost minimization studies; D) Cost consequence analysis; E) Cost-effectiveness analysis; F) Cost-utility analysis; and G) Cost-benefit analysis.
B. The local Department of Public Health (DPH) is starting a set of programs aimed at reducing childhood obesity among young children. The programs will be completely funded by a new special tax earmarked for these programs only. An expert panel recommends 6 (six) alternatives (A to F) for consideration depending upon budget size. All alternatives are mutually exclusive; i.e. can be implemented as a stand-alone project. Using cost and effectiveness data for these projects in the table, first complete the table and then respond to the questions below:

C. The Department of Revenue estimates that the special tax dedicated to funding Director's Initiative for 2014 will be $35 million. Guided by purely economic effectiveness concepts, which project(s) should the Director select and why? (The Director cannot spend more than the annual tax revenue; however, leftover funds can be carried over to the next year.)
o Will your answer change if the tax revenues were to be $70 million? Why?
o Will your answer to Question 2 change if the tax revenues were to be $120 million? Why?

o Rank the treatments by health benefit (more QALY = more benefit).
o Identify and indicate which treatment(s) are dominated for elimination.
o Show your work in calculating the ICER between each treatment option and the next most expensive option, eliminating treatment options that are not economically rational in the process due to extended dominance (higher ICER than next most expensive treatment).
o Given your calculations, and I recognize there is limited information provided so do not over-complicate, make a recommendation on which treatment should be pursued and why.
E. Consider that two drugs are available for the management of diabetic patients. The first drug costs $4,000 over 10 years. The new drug costs $7,600 over 10 years. The outcome measure, Quality Adjusted Life Years (QALY), with the first drug is 8.0 over 10 years for diabetic patients, but the QALY will improve to 9.2 with the new drug. Show you work and calculate the ICER for the new drug.
F. A public health smoking cessation program is designed to last for 3 years. The cost of implementing the program in Year 1 is $25,000; in Year 2 is $23,000; and in Year 3 is $45,000. Calculate the present value of the entire program assuming a discount rate of 4% and costs occur at the end of each year. Show your work.

o Compute the net gains (i.e., net social benefits) and the benefit-cost ratio for each project.
o If the government wanted to maximize social welfare (i.e. net social benefit), which one project listed above should be undertaken? Briefly explain.
o If the government wanted to maximize the return on its investment, which one project listed above should be undertaken? Briefly explain.
o If the government's budget was constrained to $125 million, which project or projects should it choose in order to maximize social welfare? Briefly explain. [Note: For purposes of answering this question, assume that social costs and the government's budgetary costs are identical.]
J. An insurance company wishes to determine which of five new procedures should be implemented. They decide to perform a Cost-Benefit Analysis to help them make their determination. The results of the analysis are shown in the table below.

However, he/she will remain in a less than perfect health state during the remainder of his/her life. It is assumed that the health state score will likely be between 0.6 and 0.8. Calculate the quality adjusted life expectancy for the health state range above. Show your calculation.

N. Listed below are the course of events during an Influenza season. SKETCH THESE PROBABILITIES IN A DECISION TREE MODEL. Hint: starting point is "no vaccine": if no vaccine is provided, 90% remain well and 10% become ill. Of those who become ill, 80% recovers without using any medical care but 20% visit a doctor. Of those who seek care from a doctor, 99% recover and 1% will require hospitalization. Of those who recover without any medical care, 5% are hospitalized and 95% recover.
The response should include a reference list. Double-space, using Times New Roman 12 pnt font, one-inch margins, and APA style of writing and citations.
