Conscious status is associated with the likelihood of trauma centre care and mortality in patients with moderate-to-severe traumatic brain injury.

Abstract:

OBJECTIVE:To assess the relationship between The International Classification of Diseases, Ninth Revision, Clinical Modification-derived conscious status and mortality rates in trauma centres (TC) vs. non-trauma centres (NTC). METHODS:Patients in the 2006-2011 Nationwide Emergency Department Sample meeting, The Centers for Disease Control and Prevention criteria for traumatic brain injury (TBI), with head/neck Abbreviated Injury Scale (AIS) scores ≥3 were included. Loss of consciousness (LOC) was computed for each patient. Primary outcomes included treatment at a level I/II TC vs. NTC and in-hospital mortality. We compared logistic regression models controlling for patient demographics, injury characteristics, and AIS score with identical models that also included LOC. RESULTS:Of 66,636 patients with isolated TBI identified, 15,761 (23.6%) had missing LOC status. Among the remaining 50,875 patients, 59.0% were male, 54.0% were ≥65 years old, 56.7% were treated in TCs, and 27.3% had extended LOC. Patients with extended LOC were more likely to be treated in TCs vs. those with no/brief LOC (71.1% vs. 51.4%, p < 0.001). Among patients aged <65, TC treatment was associated with increased odds of mortality [Adjusted Odds Ratio (AOR) 1.79]; accounting for LOC substantially mitigated this relationship [AOR 1.27]. Similar findings were observed among older patients, with reduced effect size. CONCLUSION:Extended LOC was associated with TC treatment and mortality. Accounting for patient LOC reduced the differential odds of mortality comparing TCs vs. NTCs by 60%. Research assessing TBI outcomes using administrative data should include measures of consciousness.
