Background Cardiovascular disease is the most common cause of death in patients with rheumatoid arthritis. It is believed that using disease‐modifying antirheumatic drugs (DMARDs) to control inflammation can reduce the risk of cardiovascular disease. In this study, we investigated whether patients who responded differently to DMARDs might sustain different cardiovascular events. Methods and Results We designed a cohort study using the Chang Gung Research Database. We identified 7114 patients diagnosed with rheumatoid arthritis. After strict exclusion criteria, we collected 663 individuals as an inadequate response to DMARDs group. Then, 2034 individuals were included as the control group. The end point was composite vascular outcomes, including acute coronary syndrome or ischemic stroke. We used the inverse probability of treatment weighting to keep the covariates between these 2 groups well balanced. We compared the risk of these outcomes using the Cox proportional hazards model. The mean follow‐up time was 4.7 years. During follow‐up, there were 7.5% and 6.4% of patients with composite vascular outcomes in the DMARD‐inadequate response and control groups, respectively. There was no significant difference in the risk of composite vascular outcomes (95% CI, 0.94–1.41) and ischemic stroke (95% CI, 0.84–1.36). The risk of acute coronary syndrome was significantly higher in the DMARD‐inadequate response group (hazard ratio, 1.45; 95% CI, 1.02–2.05). Conclusions Patients with DMARD‐inadequate response rheumatoid arthritis have a higher risk of developing acute coronary syndrome than those whose disease can be controlled by DMARDs.

Abstract Introduction/objectives The objective of this study is to describe the treatment patterns and use of healthcare resources in a cohort of Colombian patients with rheumatoid arthritis (RA) treated with biological disease-modifying antirheumatic drugs (bDMARDs) or tofacitinib. Method This is a descriptive study from a retrospective cohort of patients diagnosed with RA who were treated with bDMARDs or tofacitinib after failure of conventional DMARDs (cDMARDs) or first bDMARD. Patients who were receiving pharmacological treatment between 01 January 2014 and 30 June 2018 were included. The analysis is through the revision of claim database and electronical medical records. Demographic and clinical data were collected. The costs of healthcare resources were estimated from the billing expense of healthcare service provider. Results We evaluated 588 RA patients on treatment with bDMARDs (n = 505) or tofacitinib (n = 83), most of them were in combination with cDMARDs (85.4%). The 88.1% were females and mean age was 57.3 ± 12.5 years. The median evolution of RA since diagnosis was 9 years (IQR:4–17.2). The mean duration of use during follow-up of the bDMARDs or tofacitinib was similar, with a mean of 9.8 ± 1.9 months. It was identified that 394 (67.0%) discontinued therapy. The average annual direct cost of care per patient was USD 8997 ± 2172, where 97.2% was due to drug costs. The average annual cost of treatment per patient with bDMARDs was USD 8604 and tofacitinib was USD 6377. Conclusions In the face of a first failure of cDMARD, bDMARDs are frequently added. A high frequency of patients do not persist treatment during the first year of follow-up. The pharmacological treatment is the most representative cause of healthcare costs. Key Points• Rheumatoid arthritis is a disease with a high burden of comorbidities, complications, and worse health-related quality of life and is associated with elevated healthcare costs.• The biological disease-modifying antirheumatic drugs or tofacitinib medications are indicated for those with significant progression of the disease and when there is a need for alternatives to achieve low levels of activity and remission.• Patients with rheumatoid arthritis treated with biological disease-modifying antirheumatic drugs or tofacitinib represent a significant economic burden to the health system, especially in the costs derived from pharmacological treatment.
