Objective: Due to the amount and quality variability regarding the use of biologic therapy (BT) in psoriatic arthritis (PsA) patients, the Spanish Society of Rheumatology (SER) has promoted the generation of recommendations based on the best evidence available. These recommendations should serve as reference to rheumatologists and those involved in the treatment of patients with PsA, who are using, or about to use BT.
Methods: Recommendations were developed following a nominal group methodology and based on systematic reviews.
