Identifiers were matched with the Social Security Death Index censored for March 2005. Deaths were confirmed by death certificates, referring physicians, and medical records. Causes of death were derived by chart review or from the death certificate. Standardized mortality ratios (SMRs) and 95% confidence intervals (95% CIs) were determined.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>After excluding patients with malignancy, 110 deaths among 48,885 patients (0.23%) were confirmed. Patients had been followed up for a mean \u00b1 SD of 7.9 \u00b1 2.7 years. The SMR of the entire cohort was significantly decreased (0.65 [95% CI 0.53\u20130.78]), with differences in patients followed up for \u22659 years. The SMR was significantly greater for systemic lupus erythematosus (3.06 [95% CI 1.78\u20134.90]) and dermatomyositis (2.64 [95% CI 0.86\u20136.17]) but not for systemic juvenile rheumatoid arthritis (1.8 [95% CI 0.66\u20133.92]). The SMR was significantly decreased in pain syndromes (0.41 [95% CI 0.21\u20130.72]). Causes of death were related to the rheumatic diagnosis (including complications) in 39 patients (35%), treatment complications in 11 (10%), non\u2010natural causes in 25 (23%), background disease in 23 (21%), and were unknown in 12 patients (11%).
