Although technically CUA can be seen as simply a specific type
of CEA, we have continued to use the separate label because we
believe it is useful for several reasons.
(1) It clearly distinguishes between those studies that use a
generic measure of outcome and thus are potentially
comparable across studies (CUA), and those that use a
measure of outcome specific to the programme under study
(CEA).
(2) It highlights the crucial role of consumer preferences
(utilities) in valuing the outcomes.
(3) Because of the need to incorporate consumer preferences,
there is much that is special about CUA.
