Abstract TP228: Factors Associated with Hospital Length of Stay in Patients with Non-Traumatic Subarachnoid Hemorrhage

Introduction: Patients with non-traumatic subarachnoid hemorrhage (SAH) often have complex hospital courses, due to complications including vasospasm and hydrocephalus. Prolonged length of stay (LOS) in the hospital can be associated with unfavorable outcomes such as hospital-acquired infections, pressure ulcers, and increased burden on the healthcare system. In our cohort of patients with non-traumatic SAH, we sought to identify factors associated with LOS at our tertiary care hospital. Methods: Using ICD-10 codes, we extracted data from all patients discharged with a diagnosis of SAH at our hospital from July 2023-December 2024. Patients were excluded if they deceased in the hospital or had traumatic SAH. We collected information on sex, age, Hunt-Hess score (a clinical scale with higher ratings indicating more severe presentation), Modified Fisher score (a radiographic scale with higher ratings indicating more severe SAH), whether or not patients required open intervention for aneurysm treatment, and whether or not they had an external ventricular drain (EVD) placed. Statistics were performed in Stata software. Unpaired two-tailed t-tests were used for categorical variables. Pearson correlation coefficients were used for continuous variables and Spearman correlation coefficients were used for ordinal variables. Results: Our cohort consisted of 69 patients (Table 1). LOS was not associated with age (Pearson correlation coefficient=0.04, p=0.74), sex (mean 17.9 days in women, 14.9 days in men, p=0.21), or open intervention (mean 17.1 days in open group compared to 16.7, p=0.90). LOS was associated with Hunt-Hess score (Spearman correlation coefficient=0.48, p
