The complexity of disease and the involvement of different domains have led to the development of different clinical indices aimed to assess the disease activity in each domain. Furthermore, composite indices, able to evaluate disease activity with a single parameter, were developed. The aim of this article was to brief review the different tools to assess disease activity in skin, joint, and enthesis and to review the current evidence on the comparison of the performance of the composite indices in PsA %K psoriatic arthritis %K psoriasis %K remission %K composite indices %K disease activity %K patient-reported outcomes %U https://journals.sagepub.com/doi/full/10.1177/2475530318774266
