Is a negative ICER good?
ICERs with a negative value are in the south-east (SE) or the north-west (NW) quadrant. These two quadrants are relatively easy to interpret. In the SE quadrant the new treatment is more effec- tive and saves money compared with the old treatment. When this is the case the new treatment dominates the old treatment.
What does ICER value mean?
An ICER is calculated by dividing the difference in total costs (incremental cost) by the difference in the chosen measure of health outcome or effect (incremental effect) to provide a ratio of ‘extra cost per extra unit of health effect’ – for the more expensive therapy vs the alternative.
