Scenario 8: You are presented with the quality-adjusted life years (QALYs) for a female participant (name: Kristin) in the renal disease management program at Niagara Health. Answer questions 8.1 through 8.4. Question 8.1: Suppose Kirstin is diagnosed with renal disease that has a utility of 0 . 8 . If she lives ten years under the standard treatment with the same clinical condition, what QALYs will Kristin have in ten years? Question 8.2: If Kristin participates in a new pro-renal diet/lestyle modification program (New treatment, program 1), her utility level slightly increases to 0.9? What is the incremental beneft (i.e., QALY gain) of the new treatment program compared to the standard care in ten years? Question 8.3: If another health promotion program (Another new treatment, Program 2) prolongs Kristin's life by 5 years at a higher utility level of 0.95? What is the incremental benefit (L.e., QALY gain) of new treatment program 2 compared to the standard care? Question 8.4: What is the incremental benefit for Kristin (i.e., QALY gain) in treatment program 2 compared to treatment program 17 Maximum number of characters (including HIML tags added by text editor): 32.000
