Abstract


Abstract

Background: The accuracy of Alvarado score in diagnosing acute appendicitis in Asian population is disappointingly low. Raja Isteri Pengiran Anak Saleha Appendicits (RIPASA) a new scoring system developed for the diagnosis of acute appendicitis is claimed to be better than Alvarado scoring system in Asian population. Therefore the present study is undertaken to compare Alvarado score and RIPASA score in diagnosing acute appendicitis.

Method: A prospective comparison of RIPASA and Alvarado scoring system is done on 200 patients. A score of 7.5 was optimal cut off threshold for RIPASA and 7 for ALVARADO scoring system. Depending on clinical judgment, the decision of appendectomy was done.

Results: In this study, RIPASA score correctly classified 96 percent of all patients confirmed with histological acute appendicitis to the high probability group (score >7.5) compared with 59 percent with Alvarado score (score >7; p value <0.001). The sensitivity and specificity of RIPASA score was higher than Alvarado scoring system.

Conclusion: From the above result it can be concluded that RIPASA scoring system is more accurate, specific and hence convenient scoring system for Indian population than Alvarado scoring system.
