Application of Appendicitis Inflammatory Response (Air) Scoring System for Diagnosis of Acute Appendicitis and Its Comparison With Alvarado Score

Abstract

Background: The appendicitis inflammatory response (AIR) score is recently developed diagnostic tool that uses seven scored variables to stratify patients into low-, intermediate and high risk group.
 Methods: The present study was conducted in the department of surgery. 100 patients presenting with pain in the right lower quadrant of abdomen, who after clinical examination were provisionally diagnosed to have acute appendicitis and warranted surgery for the same.
 Results: AIR (98.00%) were more sensitive than Modified alverdo score (90.00%). Specificity (100%) and positive predict value (100%) were same in MAS & AIR.
 Conclusion: To conclude, AIR scoring performed well almost equally with Alvarado system with high specificity and high negative predictive value preventing unnecessary negative appendectomies.
