Category of presenter: Resident Objectives: We intended to determine the incidence of clinically significant findings on initial portable chest x-rays performed during the initial stabilization of the trauma patient. Methods: In this retrospective cohort study, we identified all patients who received a one-view portable chest x-ray as part of their evaluation in the trauma room of a Level 1 trauma center during a 2 year period. We randomly selected 400 of these patients to review in our study. We reviewed the Emergency Department record of those patients with predetermined traumatic injuries identified on portable chest x-ray and documented any changes in management performed as a result of the chest x-ray findings prior to leaving the trauma room or within 30 minutes of the chest x-ray, whichever occurred first. Examples of changes in management we documented in our study were therapeutic interventions such as needle decompression, tube thoracostomy, thoracentesis, or immediate transport to the operating room for a cardiothoracic surgical intervention. Our data will be analyzed with standard descriptive statistics. Results: Results are pending data collection. Conclusion: Conclusions are pending data collection and analysis.
