Abstract :
Various scoring systems have been devised to aid diagnosis of acute appendicitis. The main
objective of this study was finding the accuracy of modified Alvarado score in prediction of acute
appendicitis. The registries of cases with appendectomy, who had been admitted to a referral medical
center in the capital of Iran from February 2000 to March 2004, were studied. Sensitivity and specificity
of modified Alvarado scoring and clinical diagnostic system used in our center were calculated. ROC
curve analysis demonstrated increasing chance of acute appendicitis by increasing of the modified
Alvarado score (P = 0.001), but it was neither sensitive nor specific (sensitivity, 55%; specificity, 59%).
Diagnosis based on surgeons’ decision was more sensitive than Alvarado scoring (sensitivity 93-95% in
different age groups). Diagnosis of acute appendicitis based on surgeons’ decision is more helpful than
modified Alvarado score.
