Nhan DT, Caplan L. Patient-Reported Outcomes in Axial Spondyloarthritis. Rheumatic diseases clinics of North America. 2016 May 1; 42(2):285-99.
Axial spondyloarthritis (axSpA), a subtype of spondyloarthritis, is a debilitating inflammatory condition involving the spinal and sacroiliac joints, contributing to a significant diminution in quality of life. Historically, characterization of patient outcomes in axSpA has been a challenge due to the lack of data from longitudinal epidemiologic studies and the nonspecific nature of inflammatory laboratory markers to monitor disease activity. In this review, measures developed to address these clinical domains are discussed and compared, of which 3 are commonly used in diagnosis and therapeutic planning. Provider data regarding utilization of these measures are also included to clarify current clinical practice trends.
