Subarachnoid hemorrhage (SAH) causes significant morbidity and mortality. Pulmonary complications may be particularly frequent, but national data is lacking on the outcomes associated with acute respiratory distress syndrome (ARDS) in SAH patients. The aim of this study is to determine national trends for SAH patients with ARDS.The Nationwide Inpatient Sample Database (NIS) was utilized to sample 193,209 admissions for SAH with and without ARDS from 1993 to 2008 using ICD-9-CM coding. A multivariate stepwise regression analysis was performed.The incidence of ARDS in SAH has increased from 35.51% in 1993 to 37.60% in 2008. However, the overall mortality in SAH patients and in SAH patients with ARDS has decreased in the same period, from 42.30% to 31.99% and from 75.13% to 60.76% respectively. Multivariate analysis showed that the predictors of developing ARDS in SAH patients include older age, larger hospital size, and comorbidities such as epilepsy, cardiac arrest, sepsis, congestive heart failure, hypertension, chronic obstructive pulmonary disease, and hematologic, renal, or neurological dysfunction. Predictors of mortality in SAH patients include age and hospital complications such as coronary artery disease, ARDS, cancer, and hematologic, or renal dysfunction.SAH patients are at increased risk of developing ARDS and the identification of certain risk factors may alert and aid the practitioner in preventing worsening disease.
