Introduction: International recommendations are intended to help rheumatologists in the effective management of rheumatoid arthritis (RA) through an evidence-based approach. This research aimed to evaluate management patterns and associated difficulties encountered by rheumatologists in daily practice. Material and methods: Interviewers recruited 101 Polish rheumatologists in a random quota-based, nationwide sample of outpatient clinics. Quantitative data were input online using a computer-assisted web interview tool. Results: Disease-modifying antirheumatic drugs (DMARDs) are not initiated at the time of diagnosis in 15% of RA patients, most often due to difficulties in patient-provider communication. The RA activity is assessed every 4 to 6 months by 30% of rheumatologists, and 64% of patients are reported to never achieve remission. Composite indices are the most reliable indicators of remission only for 38% of responders. Despite inadequate disease control with ≥ 2 treatment schedules with synthetic DMARDs, 34% of these patients are not considered for biological DMARDs (bDMARDs). Contraindications and reimbursement barriers are the most frequently stated reasons. Therapy with glucocorticoid (GC) lasting over 3 months is reported by 70% of rheumatologists. International recommendations are stated as the most common basis for treatment decisions. Conclusions: Awareness of recommendations is not sufficient to ensure their application in clinical practice. Inadequate management of RA is quite prevalent, with a substantial contribution of non-medical factors. Daily practice mainly deviates from guidelines regarding frequency and mode of monitoring measures, time to DMARD initiation, and duration of GC treatment. Education programs and policy changes may significantly narrow the gap between evidence and practice.

Objectives According to the EULAR recommendations, remission or low disease activity (LDA) in rheumatoid arthritis should be achieved by a maximum of 6 months (M6) of treatment. Data on the use of tocilizumab (TCZ) as first-line biologic treatment in rheumatoid arthritis (RA) in routine clinical practice in Poland are lacking. Material and methods This multicenter, non-interventional, prospective, observational study recruited adults, presenting with moderate-to-severe RA, showing an inadequate response or intolerance to disease-modifying antirheumatic drugs, where TCZ was the first-line biologic treatment. The effectiveness of TCZ was assessed by the proportion of patients achieving remission and low disease activity following 6 months of treatment with intravenous TCZ. The impact of comorbidities on treatment outcomes was measured using the Rheumatic Disease Comorbidity Index (RDCI). Results Total remission rates at months 3 and 6 were 6% and 31%, respectively. Low disease activity was reported in 10% and 92% of the patients at 3 and 6 months, respectively. The response was comparable between TCZ as monotherapy and in combination with methotrexate. Mean DAS28 decreased from 6.61 at baseline to 4.27 at the scheduled time of the assessment (3 and 6 months). The Rheumatic Disease Comorbidity Index was not correlated with the number of patients achieving LDA at M3 and M6 or remission rates at M6. Remission rates correlated with RDCI at M3. A total of 114 adverse events were reported in 61 patients, among which five were considered as serious. Conclusions The study confirms the effectiveness and safety of TCZ in real-world settings as a first-line biologic treatment in patients with moderate-to-severe RA. Importantly, comorbidities do not affect the results of 6-month treatment with TCZ, that is, the optimal time to achieve at least LDA. Our results may improve the effects of RA therapy in Poland, especially in patients with comorbidities and those who, for various reasons, cannot receive optimal treatment with methotrexate.
