Abstract

Background: Despite mostly favorable past evidence for use of intracranial pressure monitoring (ICPM), more recent data question not only the indications but also the utility of ICPM. The Fourth Edition Brain Trauma Foundation guidelines offer limited indications for ICPM. Evidence supports ICPM for reducing mortality in patients with severe traumatic brain injury (TBI) and cites decreased survival in elderly patients. Methods: All patients ≥ 18 years of age with isolated TBI, head Abbreviated Injury Scale (AIS) ≥ 3, and a Glasgow Coma Scale (GCS) ≤ 8 between 2008 and 2014 were included from the National Trauma Data Bank. Exclusion criteria were head AIS = 6 and death within 24 hours. Patients with and without ICPM were compared using TBI-specific variables. Patients were then matched via propensity-score matching (PSM), and the odds ratio (OR) of death with ICPM was determined using logistic regression modeling for 8 different age strata. Results: A total of 23, 652 patients with a mean age of 56 years, median head AIS of 4, median GCS of 3, and overall mortality of 29.2% were analyzed. After PSM, ICPM was associated with death beginning at the age stratum of 56-65 years. Intracranial pressure monitoring was associated with survival beginning at the age-group 36-45 years. Discussion: Based on a large propensity-matched sample of TBI patients, ICPM was not associated with improved survival for TBI patients above 55 years of age. Until level 1 evidence is available, this age threshold should be considered for further prospective study in determining indications for ICPM.
