Mortality and prognostic factors among inpatients with systemic lupus erythematosus in China: A 20-year retrospective study.

From 2002 to 2013, the mortality rate among patients with SLE fell steadily but remained unchanged from 2014 to 2022. Patients with SLE had significantly higher SMR than the general population. Childhood-onset SLE had a poorer prognosis than adult-onset SLE. Infection, MODS, and NPLE were the three leading causes of death. Major organ involvement and high disease activity were risk factors for mortality.
