Developing a core outcome-domain set to assessing effectiveness of interdisciplinary multimodal pain therapy. the VAPAIN consensus statement on core outcome-domains
Interdisciplinary multimodal pain therapy (IMPT) is a biopsychosocial treatment approach for patients with chronic pain that comprises at least psychological and physiotherapeutic interventions. Core Outcome Sets (COSs) are currently developed in different medical fields to standardize and improve the selection of outcome-domains, and measurement instruments in clinical trials, to make trial results meaningful, to pool trial results, and to allow indirect comparison between interventions.
