This multicenter prospective observational study is designed to prospectively record data on patients who are managed per institutional standard of care. The objectives of this study are to establish an aggregate database of information on baseline clinical and demographic characteristics, medication use, markers of frailty, injury characteristics, management strategies, and outcomes following TBI in geriatric patients, determine best practices for management of geriatric patients with TBI, and establish how markers of frailty correlate with outcome in geriatric patients with TBI.

This is a prospective multi-center observational study of geriatric patients with TBI. Data collected will be purely observational and involve no study-based therapeutic interventions or alterations in patient care. Due to the purpose of this study being the creation of a registry and the absence of demographic information being collected, all patients meeting the inclusion criteria will be enrolled without informed consent. We plan to complete the data collection and analysis by 12/31/2018.
