Asian population-based data evaluating all-cause mortality and cause-specific mortality in patients with psoriasis are limited. This study aimed to evaluate the risk of all-cause mortality (stratified according to onset status, disease severity, and concomitant psoriatic arthritis) and cause-specific mortality in patients with psoriasis. Our study cohort consisted of 80,167 patients with newly diagnosed psoriasis between 2001 and 2012 in the National Health Insurance Database. Vital status and cause of death were ascertained from the National Death Registry of Taiwan. All-cause and cause-specific crude mortality rates and standardized mortality ratios were estimated. A total of 7,198 deaths were identified during the follow-up period (508,505 person-years). The standardized mortality ratios were 1.53 for severe psoriasis (95% confidence interval = 1.45-1.60), 1.47 for early-onset psoriasis (95% confidence interval = 1.34-1.61), and 1.47 for patients with psoriatic arthritis (95% confidence interval = 1.36-1.58). In the cause-specific mortality analysis, the absolute and excess risks of death were highest for malignancies (3.6 and 1.57 deaths per 1,000 patient-years, respectively) and circulatory system diseases (3.0 and 1.44 deaths per 1,000 patient-years, respectively). Patients with severe psoriasis, early-onset psoriasis, and psoriatic arthritis had higher all-cause mortality risks. In particular, patients with psoriasis had higher excess risks of mortality from malignancies and circulatory system diseases.
