ROUTINE PELVIC X-RAY STUDIES IN AWAKE BLUNT TRAUMA PATIENTS - A SENSIBLE POLICY

To evaluate the usefulness of routine pelvic x-ray films in the resuscitation of blunt trauma victims, 1395 patients were prospectively evaluated over a 13-month period. Of these, 810 (58%) were awake with Glasgow Coma Scale scores greater-than-or-equal-to 13 and were enrolled into the study. A history, with directed questions regarding pelvic pain, a clinical examination of the pelvis, and an anterior-posterior pelvic x-ray film (APPX) were obtained for each patient. Thirty-nine patients (5%) had fractures identified on the x-ray films. Of these patients with radiographically identified fractures, 34 (87%) complained of pain and had positive results on clinical examination, two (5%) either complained of pain or had positive results on examination and three (8%) had neither complaint of pain nor positive examination results. Of the 771 patients without fractures 743 (96%) lacked pain complaints or positive examination results. The likelihood of fracture was greatest in patients with complaints of pain and positive examination results (65%) followed by patients with either complaint of pain or positive examination results (16%). Only three (0.4%) of the 743 patients having no complaints of pain and a negative clinical examination had fractures diagnosed roentgenographically. These were minor fractures that did not affect the clinical course. Total charges incurred to diagnose pelvic fractures in this low-yield patient group were $88,028. We conclude that the practice of obtaining a screening APPX is not necessary or cost-effective in the management of awake blunt trauma patients who do not complain of pain and who have normal pelvic physical examination results.
