Predictors of Mortality in Patients With Autoimmune Diseases Admitted to the Intensive Care Unit

Autoimmune diseases, such as systemic lupus erythematosus, rheumatoid arthritis, myositis, or anti-neutrophil cytoplasmic antibody (ANCA)-associated vasculitis, may affect multiple organ systems. Occasionally, patients deteriorate acutely requiring advanced care in an intensive care unit (ICU). In an ICU setting, mortality is estimated with scoring systems, such as APACHE or SAPSII. Since there are limited data available on their use in autoimmune diseases, with the current study, we aim to assess the usefulness of these ICU scores and analyze predictors of mortality in this particular group of patients.
