Combining A4R and MCDA in priority setting for health.

Multiple criteria decision analysis (MCDA) has been proposed as a method for determining the criteria to be used in health technology assessment. A standard criticism of MCDA is that it lacks attention to securing legitimacy for its decisions. The relevance condition of A4R has been criticized for its vagueness because it lacks a focus on criteria selection. Combining the two methods addresses the central criticisms of each and provides a way of addressing the problem of priority setting for health.
