Objective: To evaluate Modified Alvarado Score in patients with right iliac fossa pain. Design & Duration: Prospective cross-sectional study from March 2006 to May 2007. Setting: District Headquarter (DHQ) Hospital, Charsadda. Patients: One hundred consecutive patients with right right iliac fossa pain. Both male and female patients with ages >14 years were included Methodology: Basic data of all the patients was collected. They were divided into two groups on the basis of modified Alvarado score. Group-I: Alvarado score >= 7. Group-II: Alvarado score <= 7. Results: In Group-I 61 patients underwent surgery; amongst them 52 had acute appendicitis while nine had other pathology. In Group-II there were 39 patients; amongst them six underwent surgery later on because of increase in their scores during observation, all of them had acute appendicitis. The negative appendicectomy rate was 14.75% and positive predictive value 85.21%. Conclusion: Alvarado Score is an easy and simple complementary aid in the diagnosis of acute appendicitis. It works well in patients with a score of >= 7.
