Observational StudyValidation of the Sonographic Ottawa Foot and Ankle Rules (SOFAR) Study in a Large Urban Trauma Center.
Differentiating the severity of acute ankle injuries is a common problem in the emergency department (ED). The Ottawa Foot and Ankle Rules (OFAR) were designed to obviate the need for unnecessary x-rays. Although these rules have been determined to be very sensitive, they lack the specificity necessary to make them practically useful for a condition in which a misdiagnosis could result in a significant disability. Our study objective was to determine if the addition of a bedside ultrasound (US) to the evaluation process could be used to significantly reduce the number of negative x-rays in OFAR positive patients. ⋯ Among OFAR positive patients, bedside US has high sensitivity and specificity for detecting foot and/or ankle fractures. Further studies should be conducted to determine if utilizing bedside US in addition to OFAR could significantly reduce the number of x-rays and improve the efficiency and costs associated with evaluating these injuries in the ED. Implication for health policy/medical education/research/ practice. Utilizing bedside ultrasonography in addition to Ottawa Foot and Ankle Rules in acutely injured patients could significantly reduce the number of ordered x-rays and length of stay in the emergency department.
