Abstract Objectives The primary objective was to determine the diagnostic accuracy of a serial ultrasound (US) clinical diagnostic pathway to detect appendicitis in children presenting to the emergency department (ED). The secondary objective was to examine the diagnostic performance of the initial and interval US and to compare the accuracy of the pathway to that of the initial US. Methods This was a prospective cohort study of 294 previously healthy children 4 to 17 years old with suspected appendicitis and baseline pediatric appendicitis scores of ≥2, who were managed with the serial US clinical diagnostic pathway. This pathway consisted of an initial US followed by a clinical reassessment in each patient and an interval US and surgical consultation in patients with equivocal initial US and persistent concern about appendicitis. The USs were interpreted by published criteria as positive, negative, or equivocal for appendicitis. Children in whom this pathway did not rule in or rule out appendicitis underwent computed tomography (CT). Cases with missed appendicitis, negative operations, and CTs after the pathway were considered inaccurate. Toca Race Driver 3 Camera Hack.

The secondary outcomes included the test performance of the initial and interval US imaging studies. Results Of the 294 study children, 111 (38%) had appendicitis. Using the serial US clinical diagnostic pathway, 274 of 294 children (93%, 95% confidence interval [CI] = 90% to 96%) had diagnostically accurate results: 108 of the 111 (97%) appendicitis cases were successfully identified by the pathway without CT scans (two missed and one CT), and 166 of the 183 (91%) negative cases were ruled out without CT scans (14 negative operations and three CTs). The sensitivity of this pathway was 108 of 111 (97%, 95% CI = 94% to 100%), specificity 166 of 183 (91%, 95% CI = 87% to 95%), positive predictive value 108 of 125 (86%; 95% CI = 79% to 92%), and negative predictive value 166 of 169 (98%, 95% CI = 96% to 100%). The diagnostic accuracy of the pathway was higher than that of the initial US alone (274 of 294 vs.

160 of 294; p. • • Serial US clinical diagnostic pathway. PAS = pediatric appendicitis score; RLQ = right lower quadrant; US = ultrasound. Study Setting and Population The study took place at a Canadian pediatric hospital with about 250 trauma team activations in our ED annually, of which 125 have an Injury Severity Score of >12. We chose a consecutive sample of previously healthy children 4 to 17 years old with abdominal pain and right lower quadrant abdominal tenderness, as defined by an initial PAS ≥ 2 points, who in the opinion of the ED staff physician/fellow required imaging (US represents the initial imaging at our institution) for suspected appendicitis. This PAS cutoff reflects a conservative imaging practice of some physicians to ensure that appendicitis is not missed.
