This study was to determine the correlation between the Alvarado score and the histopathological profile of appendicitis. It assesses appendicitis diagnosis accuracy based on the Alvarado score at the Academic Hospital of UGM.Methods: This study was a cross-sectional design study with a diagnostic test method using secondary data from 173 appendicitis patients from 1 January to 31 December 2019, who met the inclusion and exclusion criteria.Results: According to the histopathology result, the finding of acute appendicitis was 95.95%, which Alvarado score of ≥7 was 71.68%. The overall sensitivity, specificity, accuracy, positive predictive value, and negative predictive value of Alvarado score for acute appendicitis were 73.49%, 71.43%, 73.41%, 98.39 %, 10.20%, respectively.
