Scenario 9: A health economist has undertaken the one-way deterministic sensitivity analysis of a new stroke management program compared with the status quo. The base-case ICER is $1500 per QALY gain. Please refer to the attached table for sensitivity ICERS, when QALY and cost parameters were manually changed. Answer questions 9.1 through 9.3. Question 9.1: Calculate % change in the base-case ICERs for utilities of stroke patients when the QALY parameter was assumed lower and higher values, respectively. Refer to the Tornado table attached. (% change in the base-ICER when assumed lower value: ___;% change in the base-case ICER when assumed higher value: Question 9.2: Calculate % change in the base-case ICERs for hospitalization when cost parameter was assumed lower and higher values, respectively. Refer to the Tornado table attached. (% change in the base-ICER when assumed lower value: % change in the base-case ICER when assumed higher value: Question 9.3: Calculate % change in the base-case ICERs for intervention when cost parameter was assumed lower and higher values, respectively.
