Question What happens to patients with traumatic brain injury (TBI) who are transferred to higher-level trauma centers?
Findings In this study of 117 651 patients with isolated TBI with intracranial hemorrhage managed at the American College of Surgeons level I/level II trauma centers, 53 108 patients transferred from other centers were identified. Nearly half of the patients with TBI managed at the American College of Surgeons level I/level II trauma centers were transferred from lower-level hospitals and one-third of these transferred patients were discharged within 48 hours without any neurosurgical interventions.
Meaning These findings indicate the need for systemwide guidelines to improve health care resource utilization and guide triage of patients with TBI.
Abstract
Importance Wide variations exist in traumatic brain injury (TBI) management strategies and transfer guidelines across the country.
Objective To assess the outcomes of patients with TBI transferred to the American College of Surgeons (ACS) level I (LI) or level II (LII) trauma centers (TCs) on a nationwide scale.
Design, Setting, and Participants In this secondary analysis of the ACS Trauma Quality Improvement Program database (2017 to 2020), adult patients with isolated TBI (nonhead abbreviated injury scale = 0) with intracranial hemorrhage (ICH) who were transferred to LI/LII TCs we re included. Data were analyzed from January 1, 2017, through December 31, 2020.
Main Outcomes and Measures Outcomes were rates of head computed tomography scans, neurosurgical interventions (cerebral monitors, craniotomy/craniectomy), hospital length of stay, and mortality. Descriptive statistics and hierarchical mixed-model regression analyses were performed.
Results Of 117 651 patients with TBI with ICH managed at LI/LII TCs 53 108; (45.1%; 95% CI, 44.8%-45.4%) transferred from other centers were identified. The mean (SD) age was 61 (22) years and 30 692 were male (58%). The median (IQR) Glasgow Coma Scale score on arrival was 15 (14-15); 5272 patients had a Glasgow Coma Scale score of 8 or less on arrival at the receiving trauma center (10%). A total of 30 973 patients underwent head CT scans (58%) and 2144 underwent repeat head CT scans at the receiving TC (4%). There were 2124 patients who received cerebral monitors (4%), 6862 underwent craniotomy/craniectomy (13%), and 7487 received mechanical ventilation (14%). The median (IQR) hospital length of stay was 2 (1-5) days and the mortality rate was 6.5%. There were 9005 patients (17%) who were discharged within 24 hours and 19 421 (37%) who were discharged within 48 hours of admission without undergoing any neurosurgical intervention. Wide variations between and within trauma centers in terms of outcomes were observed in mixed-model analysis.
Conclusions In this study, nearly half of the patients with TBI managed at LI/LII TCs were transferred from lower-level hospitals. Over one-third of these transferred patients were discharged within 48 hours without any interventions. These findings indicate the need for systemwide guidelines to improve health care resource use and guide triage of patients with TBI.
