jats:titleAbstract</jats:title> jats:pBackground/Aims </jats:p> jats:pMultidisciplinary (MD) care is essential in the management of patients with spondyloarthritis (SpA), but evidence supporting its effectiveness and benefits in SpA is scarce.The objectives of this review were to describe the characteristics, effectiveness and feasibility of MD working compared to uni-disciplinary approach in studies of patients with SpA.</jats:p> jats:pMethods </jats:p> jats:pA literature review was conducted according to the PICO framework. We included studies on patients with axial and/or peripheral SpA, and we assessed several outcomes such as diagnosis, treatment, feasibility, disease and patient-related outcomes (Table 1).</jats:p> jats:pResults </jats:p> jats:pFifteen articles met the review’s eligibility criteria, including 13 observational studies and two randomised controlled trials. In total 4,312 patients were analysed, including patients with psoriatic arthritis, enteropathic SpA, ankylosing spondylitis, and SpA with anterior uveitis. Most of the studies included a combined clinic encompassing a rheumatologist and another specialist, most commonly a dermatologist or a gastroenterologist, working in tandem according to predefined referral criteria and treatment algorithms. The main outcomes assessed in studies on MD working in SpA, matched with their outcome measures are depicted in Table 1. MD working was reported to lead to better outcomes in all studies, including: better identification and diagnosis of the disease; earlier and more comprehensive treatment approach; and better outcomes for patients in terms of disease activity, physical function, quality of life and patient satisfaction. However, these results are mostly derived from studies with design issues and without a uni-disciplinary care comparator arm.</jats:p> jats:pConclusion </jats:p> jats:pDespite the lack of strong and reliable evidence to support its benefits compared to standard care, MD working is an essential part of the care of patients with SpA. Further studies and initiatives should be developed so that the challenges and limits of MD care can be improved upon.
