Predicting Acute Appendicitis? A comparison of the Alvarado Score, the Appendicitis Inflammatory Response Score and Clinical Assessment

Background Patients presenting with suspected appendicitis pose a diagnostic challenge. The appendicitis inflammatory response (AIR) score has outperformed the Alvarado score in two retrospective studies. The aim of this study was to evaluate the AIR Score and compare its performance in predicting risk of appendicitis to both the Alvarado score and the clinical impression of a senior surgeon.
