182 Impact of Intracranial Pressure Monitoring Type on Outcomes of Severe Traumatic Brain Injury Experience of 2 Academic Institutions Over 8 Years

Abstract

INTRODUCTION: Severe traumatic brain injury (sTBI) is a major cause of mortality and long-term disability. Though intracranial pressure (ICP) monitoring is recommended in sTBI management, the choice between external ventricular drain (EVD) and parenchymal monitor is still multifactorial. Herein, we aimed to assess the effect of ICP monitoring type on mortality and functional outcomes of sTBI patients. METHOD(S): We retrospectively identified sTBI patients admitted 2007-2015 in 2 academic institutions databases using ICD9/10 TBI diagnosis code. sTBI was defined as the presence of ICP monitor and ventilatory assistance for >24 h consecutively. Functional outcome and mortality rate were recorded. Statistical analysis was done in R (Ver 3.4.0). RESULT(S): A total of 597 patients with ICP monitor were identified, of which 44.7% had an EVD. Age (47.7 +/- 19.9 yr) and sex (80.6% males) were similar between the groups. Compared to non-EVD group, EVD cohort was more likely to have open skull fracture (9.7% vs 5.2%, P =.046), intracerebral hemorrhage (83.1% vs 67.9%, P
