To evaluate a 4-hour ultrasonography course in the setting of an emergency medicine (EM) training program. EM residents and faculty at a large urban center were provided a 4-hour emergency ultrasonography course. Then, during an 18-month period, a nonconsecutive sample of ultrasonographic examinations were videotaped and later reviewed. The interpretations of the emergency, physician examinations were compared with the following reference standards: 1) an official ultrasound performed and interpreted by the departments of radiology or cardiology; 2) an operative report; 3) A CT scan or i.v. pyelogram (IVP); or 4) a cardiologist's or a radiologist's interpretation of the videotaped examinations. Of 258 examinations reviewed, 28 (11%) of these were excluded because the cardiologist or radiologist reviewing the videotape determined them to be "technically limited" studies. Of the remaining 230 examinations, there were: 127 gallbladder studies [disease prevalence = 0.58; sensitivity = 0.89; specificity = 0.80; kappa (kappa) = 0.69; 95% CI: 56-82%]; 39 echocardiograms to rule out pericardial effusions [disease prevalence = 0.15; sensitivity = 0.83; specificity = 0.97 kappa = 0.80; 95% CI: 54-100%]; 25 abdominal ultrasounds to rule o...Continue Reading
