Early Predictors of Near-Shore Spinal Injuries Among Emergency Department Patients.

Background: Spinal injuries (SIs) can pose a significant burden to patients and family; delayed surgical intervention, associated with interhospital transfer, results in worse outcomes.
Objective: This study aimed to identify early patient-centered factors associated with risk for near-shore SIs to assist clinicians with expeditious medical decision-making.
Methods: We performed a multicenter retrospective study of all adults transported from Ocean City, Maryland to two emergency departments (EDs) and one regional trauma center for evaluation of suspected SIs from 2006 to 2017. Outcomes were any SI and any spinal cord injury (SCI). Multivariable logistic regression was performed for association of environmental and clinical factors with outcomes.
Results: We analyzed 278 records, 102 patients (37%) were diagnosed with any SI and 41 (15%) were diagnosed with SCIs. Compared with patients without SI, patients with SI were more likely to be older (48 vs. 39 years), male (90% vs. 70%), with pre-existing spinal condition (62% vs. 33%), and injury caused by diving (11% vs. 2%). Multivariable logistic regression showed age (odd ratio [OR] 1.07; 95% confidence interval [CI] 1.04-1.11), diving (OR 3.5; 95% CI 3-100+), and wave height (OR 4.5; 95% CI 1.35-15.2) were associated with any SI, and a chief complaint of extremity numbness or tingling (OR 5.73; 95% CI 1.2-27.9) was associated with SCI.
Conclusions: We identified older age, diving, and higher wave height as risk factors for any SI and symptoms of numbness and tingling were associated with SCIs. Clinicians should consider expediting these patients' transfers to a trauma center with neurosurgical capability.
