ObjectivesTo examine the practice of clinically "clearing" the cervical spine (c-spine) of trauma patients brought to the ED by EMS with cervical immobilization in place, and to examine developing trends in prehospital c-spine clearance.MethodsA 12-question survey form was mailed to the physician medical directors of 300 randomly selected EDs. Questions examined ED clinical clearance practices, EMS clearance protocols and research, and attitudes toward prehospital clearance. Estimated clinical clearance rates were requested.ResultsA total of 173 surveys were returned (58%). At 21 hospitals (12%), c-spine films are obtained for all immobilized trauma patients; clinical clearance is never attempted. Of the remaining 151 hospitals, on average, clinical clearance is attempted for 65.5% of these patients (range 3-100%, interquartile range 50-100%) and is successful (films are not obtained) for 53.7% of attempts (range 0-100%, interquartile range 35-75%). No differences exist in either attempt rate or success rate between trauma centers and non-trauma centers, or between academic/university hospitals, community teaching hospitals, and community non-teaching hospitals (t-test or ANOVA, p > 0.05). Seventy-two respondents (42%) reported significant variation in clinical clearance practice patterns among their ED physicians. Seventy-three respondents (42%) feel that EMS providers should immobilize all trauma patients, while 99 (57%) feel it is reasonable for trained EMS providers to attempt clinical clearance on low-risk trauma patients.ConclusionsThere is tremendous variation in the ED practice of clinically clearing cervical spines. This, and a lack of support from many ED directors, may hinder attempts at development of research and standardized protocols for pre-hospital c-spine clearance.
