[Cost Effectiveness of Treatments of Psoriasis with a PASI 75 and one Period of 12 Weeks].

Objective: The objective was to evaluate the efficiency (relation between the cost and the results in health) of the treatments in psoriasis, seeking a higher quality of economic evaluations, consistency and transparency in these studies.

Methods: We developed a model of economic evaluation in psoriasis collecting all the many direct and indirect costs of each treatment. The effectiveness indicator used was Psoriasis Area Severity Index [PASI 75] which is generally acceptable in studies of psoriasis.
