Impact of Clinical Specialty Setting and Geographic Regions on Disease Management in Patients with Psoriatic Arthritis in the United States: A Multicenter Observational Study.

Abstract：

BACKGROUND:Information on the factors that influence treatment management decisions for psoriatic arthritis (PsA) is limited. OBJECTIVE:Our objective was to evaluate the impact of clinical specialty setting and geographic region on the management of patients with PsA in the USA. METHODS:LOOP was a multicenter, cross-sectional, observational study conducted across 44 sites in the USA. Patients were aged ≥ 18 years with a suspected or established diagnosis of PsA and were routinely visiting a rheumatologist or dermatologist. All patients enrolled in the study were assessed by both a rheumatologist and a dermatologist. Primary outcomes were the times from symptom onset to PsA diagnosis; PsA diagnosis to first conventional synthetic disease-modifying antirheumatic drug (csDMARD); PsA diagnosis to first biologic DMARD (bDMARD); and first csDMARD to first bDMARD. RESULTS:Of 681 patients enrolled in the study, 513 had a confirmed diagnosis of PsA and were included in this analysis. More patients were recruited by rheumatologists (71.3%) than by dermatologists (28.7%). The median time from symptom onset to diagnosis of PsA was significantly shorter for patients enrolled by rheumatologists than for those enrolled by dermatologists (1.0 vs. 2.6 years; p < 0.001). Disease activity and burden were generally similar across enrolling specialties. However, patients in western areas of the USA had less severe disease than those in central or eastern areas, including measures of joint involvement, enthesitis, and dactylitis. CONCLUSIONS:There was a substantial delay in the time from symptom onset to diagnosis in this study population, and this was significantly longer for patients enrolled in the dermatology versus the rheumatology setting. This supports the need for collaboration across specialties to ensure faster recognition and treatment of PsA.
