[Cross-sectional study on clinic behavior and therapeutic status of patients with psoriatic arthritis in multi-center].

ABSTRACT

OBJECTIVE: To investigate and analyse the features of treatment behavior and standardized therapeutic status of patients with psoriatic arthritis (PsA). METHODS: Out patients diagnosed with PsA in People's Hospital of Peking University, Haidian Hospital, People's Hospital of Jianyang City, Central Hospital of Xinxiang City, Integrated Traditional Chinese and Western Medicine Hospital of Cangzhou City, The Third Hospital of Hebei Medical University from February to June 2018 were enrolled in this investigation. The data including gender, age of onset, course of disease, site of first consulting department, time of the first visit and definite diagnosis, follow-up interval, and use of conventional disease modifying anti-rheumatic drugs (cDMARDs) and biological DMARDs (BioDMARDs) were collected and analyzed. RESULTS: In the cross-sectional study, 133 PsA patients were investigated. The mean age of onset was (47±11) years, the male to female ratio was 1.31, and mean disease duration was (16±8) years. Rheumatology department was the most common site of first hospital visit (37.6%, 50/133). Orthopedics department and dermatological department were visited by 24.1% (32/133) and 23.3% (31/133), respectively. Ratio of definite diagnosis was the highest in rheumatology department which was 78% (39/50). The ratio of definite diagnosis of dermatological department was the second highest, which was 19.4% (6/31). The mean definite diagnosed time was 7.6 months since the first visit of PsA patients, and diagnosed time was the shortest in rheumatology department, which had statistical significance. 37% PsA patients were treated appropriately in 3 months, 17.3% PsA patients were treated in 3-6 months and 40.2% patients with PsA visited their doctor more than once a year. 48.8% patients hadn't received standardized treatment before visit, and one third patients never received the therapy of DMARDs. Methotrexate was the most commonly used cDMARDs (58.3%), followed by leflunomide (20.5%) and BioDMARDs (19.7%), and biologicals were tumor necrosis factor antagonists. CONCLUSION: In this multi-center study, the first visit department of PsA patients was widely distributed, and most patients were definitely diagnosed in Rheumatology Department. The time of their first visit and definite diagnosis were delayed due to multi factors. Nearly half of the patients did not receive standardized treatment.
