ObjectiveTo determine whether paramedics can safely use a spinal clearance algorithm to reduce unnecessary spinal immobilization (SI) in the out-of-hospital setting.MethodsParamedics were instructed in the use of a spinal clearance algorithm that prompted assessment of the trauma patient's 1) level of consciousness, 2) drug and/or alcohol use, 3) loss of consciousness during the event, 4) presence of spinal pain/tenderness, 5) presence of neurologic deficit, 6) concomitant serious injury, or 7) presence of pain with range of motion. The algorithm indicated that if any of the above were present, the patient should receive full SI, and if all of the above were negative, then SI could be withheld. Paramedics completed a tracking form that included the above and followed the patient to the emergency department (ED). Data were then gathered to determine the presence of spinal fracture, neurologic deficit, or a combination of the two. To compare the trends for SI, a retrospective medical incident report (MIR) review was conducted from the previous year. MIRs were selected based on the same criteria as those used for study inclusion.ResultsTwo hundred eighty-one patients were included in the study, with 65% (n = 183) of them receiving SI. Two hundred ninety-three MIRs were included in the retrospective sample, with SI being provided 95% (n = 288) of the time. Comparison of these samples shows a 33% reduction in utilization of SI (95% confidence interval: 27.2%- 38.8%).ConclusionAn out-of-hospital spinal clearance algorithm administered by paramedics can reduce SI by one-third. Any application of a spinal clearance algorithm should be accompanied by rigorous medical supervision.
