Health Economist wants to present four ICERS to the policymaker. See figure and name the quadrant for each ICER value. Answer questions 4.1 through 4.4. Question 4.1: Which quadrant it falls if an ICER of the blindness control program is $45,000 per QALY gain (i.e., more costly and more effective)? Question 4.2: What if the ICER of blindness control program indicates that new intervention is more costly and not effective at all. Question 4.3: What if the ICER of blindness control program indicates that new intervention is less costly and less effective. Question 4.4: What if the ICER of blindness control program indicates that new intervention is less costly and more effective. Cost-effectiveness Acceptability Plane Less effective (Decrease in QALYS) North-West South-West More Costly North-East South-East More effective ncrease in QALYS)
