A prospective evaluation of the modified Alvarado score for acute appendicitis in children.
The accuracy of the modified Alvarado score was assessed prospectively in the preoperative diagnosis of acute appendicitis in children. A consecutive series of 118 patients (54 boys, 64 girls) with acute abdominal pain was studied prospectively over a 6 month period. Appendicitis was confirmed in 38 of 43 children undergoing appendicectomy, giving a false-positive appendicectomy rate of 11.6%. No child under active observation was subsequently found to have a perforated appendix. The overall sensitivity of a modified Alvarado score of > or = 7 was 76.3% and its specificity was 78.8%. Current clinical practice is more accurate than the modified Alvarado score in the diagnosis of acute appendicitis in children.
