<h3>Background</h3> Patients with rheumatoid arthritis (RA) have a high mortality rate compared to the general population<sup>1</sup>. However, the mortality rate of patients with RA might be improved by advances in therapy<sup>2</sup>. <h3>Objectives</h3> We investigated the risk factors for mortality in patients with RA from TOMORROW study. <h3>Methods</h3> This study included 413 participants, comprising 208 patients with RA and 205 age- and sex- matched healthy volunteers (Vo) from the prospective "TOMORROW" cohort study that has been ongoing since 2010 were included in this study (women, 84%; mean age, 58 years old). Median disease duration was 10.3 years. <h3>Results</h3> The rate of accomplishment for 8 years was 83.2% in the RA group and 92.7% in the Vo group. There were 14 deaths in the RA group (8.7/1000 person-years) and two in the Vo group (1.2/1000 person-years) (p=0.0025) for 8 years. Infection was the most common cause of death in the RA group (43%). Cox proportional hazard analysis showed that having RA was significant risk factor for death (hazard ratio [HR]: 6.9, 95%CI: 1.6 - 30.4, p=0.01) adjusting by age (Figure). In the RA group, glucocorticoid (GC) use (HR: 3.6, 95%CI: 1.1 -10.4, p=0.032) was significant risk factor for death. Disease activity, duration of disease, use of biological products, use of methotrexate, presence of cardiovascular disease, and smoking were not significant factor. <h3>Conclusion</h3> RA was still significant risk factor of death. GC use was independent factors of death in RA patients. <h3>References</h3> [1] van den Hoek J, Boshuizen HC, Roorda LD, et al.
