False-Negative FAST Examination: Associations With Injury Characteristics and Patient Outcomes

Annals of Emergency Medicine, 04/20/2012

Patients with severe head injuries and minor abdominal injuries were more likely to have a false–negative than true–positive Focused assessment with sonography in trauma (FAST) result. On the other hand, patients with spleen, liver, or abdominal vascular injuries are less likely to have false–negative FAST examination results. Adverse outcomes were not associated with false–negative FAST examination results, and in fact patients with false–negative FAST result were less likely to have a therapeutic laparotomy. Further studies are needed to assess the strength of these findings.
