Is older age an appropriate criterion alone for ordering cervical spine computed tomography after trauma

Abstract

AbstractBackgroundCervical spine computed tomography (CSCT) scans are frequently performed in older emergency department (ED) trauma patients based on the 65‐year‐old high‐risk criterion of the Canadian Cervical Spine Rule (CCR). We sought to determine the positivity rate of CSCT scans in symptomatic and asymptomatic patients to assess the current applicability of age in the CCR.MethodsWe reviewed CSCT ED reports from two institutional hospitals from 2018 to 2023. The primary variable was age; however, we also recorded fracture types and sites and type of treatments. Patients were separated into symptomatic and asymptomatic cohorts. We used a Fisher's exact test to compare variables between the asymptomatic and symptomatic groups and chi‐square tests for comparison between age groups.ResultsOf 9455 CSCTs performed in patients ≥ 65 years, 192 (2.0%) fractures were identified (113 females); 28 (0.30%) were in asymptomatic patients. The rates of fractures (1.6%) and asymptomatic fractures (0.18%) were lowest in the 65‐ to 70‐year age group. There were no distinguishing features as to the level or part of the vertebra fractured or surgical treatment rate between asymptomatic and symptomatic patients.ConclusionsCervical spine fractures in posttrauma patients ≥ 65 years are uncommon, with the lowest incidence in those 65 to 70 years old. Excluding asymptomatic individuals aged 65–70 from routine CSCT presents a minimal risk of missed fractures (0.18%). This prompts consideration for refining age‐based screening and integrating shared decision making into the clinical protocol for this demographic, reflecting the low incidence of fractures and the changing health profile of the aging population.
