EVALUATION OF RIPASA SCORE COMPARED TO ALVARADO SCORE IN THE DIAGNOSIS OF ACUTE APPENDICITIS

Dr. Farrukh Hassan, Dr. Doddy Ishanshu Mishra

Abstract :

Background: In a recent study, a new clinical scoring system named as Raja Isteri Pengiran Anak Saleha Appendicitis (RIPASA) scoring was hypothesized. In this study an attempt is made to compare the diagnostic accuracy between these two scoring systems and to draw a conclusion that which scores is more accurate and cost effective in respect to our socio-economic condition and also to minimize the negative appendectomy as much as possible. Materials and methods : All patients undergoing Appendicectomy for the provisional diagnosis of Appendicitis from April 2018 to October 2019 in Department of General Surgery, RAJENDRA INSTITUTE OF MEDICAL SCIENCES, Ranchi were included in the study. Results : The RIPASA score correctly classified 79 (97.5%) patients confirmed with histological acute appendicitis to the high-probability group (RIPASA score ≥ 7.5) compared with 69 (55.5%) patients with Alvarado score ≥ 7.0. The diagnostic accuracy was 95.15% (95% CI 89.14%-97.9%), for the RIPASA score and 64.08% (95% CI 54.46%-72.69%) for the Alvarado score, showing a difference of 31.07% (p < 0.001), which was statistically significant. Conclusion: The RIPASA score is a better tool in evaluation of suspected appendicitis based on the more sensitivity and more negative predictive value in comparison to ALVARADO.
