Analysis of the first 5 years of an interdisciplinary Rheumatology-Dermatology clinic

Multispeciality clinics, such as combined psoriasis-psoriatic arthritis clinics, have shown improved outcomes in various diseases. At Massachusetts General Hospital, we are entering our ninth year of having an interdisciplinary Rheumatology-Dermatology (R-D) clinic.

To evaluate the contribution of an R-D clinic by comparing care of patients pre- and post-evaluation in the combined clinic. As proxies of care, rates and comprehensiveness of evaluations (capillaroscopic examination, skin and joint examination) were compared between the combined clinic and standard Rheumatology or Dermatology clinic.

This was a retrospective chart review of patients at the R-D clinic in Massachusetts General Hospital during the period November 2012 to December 2017.

Prior to the patients visiting the R-D only 5% of capillaroscopic examinations were documented, only 5% of rheumatologists specifically described a rash even when present, and pruritus was documented in only 6% of rheumatology notes. By contrast, in the R-D clinic, capillaroscopic, skin and joint examinations were documented in 100% of visits, and 19% of patients were given a different or a refined diagnosis. Although all our patients had cutaneous manifestations of their disease (hair loss, rash, itch, Raynaud phenomenon, ulcerations, calcinosis) only 34% had seen a dermatologist prior to the combined clinic and only 5% of those had had their concerns addressed by the rheumatologist. This suggests that 95% had a more complete evaluation and management of all aspects of their disease by attendance at the R-D clinic.

Despite this study being limited by its retrospective nature, we found that it is an efficient model to achieve more comprehensive and potentially lower medication costs. Collaboration between dermatologists and rheumatologists in a combined clinic led to more complete skin and joint examinations, consistent tracking of capillaroscopic examination, better description of rash and improved management. Having this clinic helped in reaching a diagnosis and overall better disease control and outcome.
