Background: Rheumatologists and Dermatologists usually manage Psoriatic Arthritis (PsA) and Psoriasis (PsO) separately, but early diagnosis and integrated management could achieve better outcomes with gains in quality of life of the patients. A multidisciplinary care is essential to achieve these goals. Objectives: The aim of this study is to describe a model of integrated multidisciplinary approach for early diagnosis of PsA and the multidisciplinary management of PsA patients. Methods: A retrospective study including patients that attended the multidisciplinary clinical from January 2019 to December 2020 was performed. Patients with PsO complaining articular symptoms and patients with articular symptoms with cutaneous lesions suspected to be PsO was referred to this clinical. Demographic, clinical data and disease activity measures were collected. Descriptive, Student’s t and Fisher test and Odds Ratio were estimated. Results: A total of 50 patients were referred to multidisciplinary clinical. Of these, 40 patients met criteria for psoriatic arthritis according to CASPAR criteria: 22 (55%) were male and median age was 49.5 ± 11.5 years. Family history of psoriasis was present in 19 (47.5%) and 7 (17.5%) had spondyloarthritis family history. Obesity and overweight were the comorbidities most found, 42.9% and 37.1%, respectively, followed by hypertension 25%, dyslipidaemia and depression 22.5% and metabolic syndrome 15%. Thirty-three patients (84.6%) were under topical treatment, 23 (59%) were under csDMARDs and 13 (32.5%) were under bDMARDs. After multidisciplinary clinical evaluation, treatment change was made - switch to another bDMARDs in 5 patients and bDMARD was started in 7 patients. All patients had a previous evaluation for infection risk assessment and 11 patients performed 9 months isoniazid for latent tuberculosis treatment. Eleven patients (28.9%) presenting moderate to severe PASI. Thirty-one patients presenting prolonged disease duration (&gt; 10 years) with cutaneous (74.2%) and articular (61.3%) involvement. Peripheral disease without axial involvement was present in 28 patients (90%) while the others (10%) had both axial and peripheral involvement. Severe or moderate articular disease activity (DAS28) was present in 52.6% of the patients. The most frequent extra-articular manifestation was dactylitis (23.3%) and enthesitis (19.4%). The average number of multidisciplinary clinical consultations for these patients was 2. There was a statistically significant difference at the mean age, gender and disease duration &gt; 10 years between patients with psoriatic disease with and without arthritis (p= 0.047; p=0.01 and p=0.03, respectively); there was no statistically significant differences in family history of psoriasis (p=0.711) and spondyloarthritis (p=0.174), nutritional status (p=0.732) and comorbidities such as diabetes mellitus (p=0.545), hypertension (p=0.404), dyslipidaemia (p=0.394) and depression (p=0.089). In the remaining 10 patients screened, the osteoarthritis and/or tendonitis were responsible for the articular complaints in 6 patients and scalp seborrhoea and eczema were responsible for the cutaneous complaints in the rest. Conclusion: Despite the small number of patients observed in our multidisciplinary clinical, we found that this kind of clinical care may facilitate the diagnosis of joint disease and offers a more comprehensive treatment approach for patients with both psoriasis and PsA.
