What are "total cost comparisons, cost-effectiveness analysis (CEA) or related types of economic evaluation?"

Awardees are reminded that PCORI will not fund research that compares and contrasts interventions on the basis of comparative costs or cost-effectiveness. This includes methods known as cost-effectiveness, cost-benefit, cost-minimization, cost-consequences, cost-feasibility and cost-utility analyses. Comparison of elements of an intervention or comparison of domains of costs or other economic burdens are acceptable. Awardees are encouraged to be as specific as possible about their intended analysis.
