Key clinical point: Mortality risk varied with time and increased only during the second not the first decade after the diagnosis of rheumatoid arthritis (RA), with respiratory diseases potentially surpassing cardiovascular diseases as major attributable factors.
Major finding: Increase in mortality was observed at 20 years (standardized mortality ratio [SMR] 1.49; P < .001) but not during the first 10 years (P = .44) after RA diagnosis, with pneumonia (cause-specific SMR 5.22; 95% CI 2.26-10.29) and interstitial lung disease (cause-specific SMR 7.64; 95% CI 2.98-14.69) being major contributors.
Study details: Findings are from an analysis of 1895 patients with RA from the Australian Rheumatology Association Database (ARAD) registry who received biologic, targeted synthetic, or conventional synthetic disease-modifying antirheumatic drugs.
Disclosures: ARAD received support through the Australian Rheumatology Association from various sources. Three authors declared receiving grants, funding, or honoraria from different sources unrelated to this study.
