Situation: two treatments A and B both indicated for a disease
Parameters:
(1) cost of treatments A and B (objective)
(2) relative effectiveness of treatments A and B (objective)
(3) whether any differences in effectiveness are "worth it" (subjective)
Select treatment A over B if one or more of the following is present:
(1) (its cost is less than B) AND (it is at least as effective = same or greater effectiveness)
(2) (its cost is less than B) AND (it is less effective than B) AND (the greater effectiveness of B is not worth it)
(3) (its cost is greater than B) AND (its is more effective than B) AND (the greater effectiveness of A is worth it)
A complete selection process might take from 1 to 3 steps:
(1) running the scenarios with A vs B. If A not selected, then go to 2.
(2) running the scenarios with B vs A. If B not selected then go to 3.
(3) select either A or B (roughly equivalent)
