RESUMO

Background: Different scoring systems have been created to increase diagnostic accuracy, and they are inexpensive, non-invasive, and easy to use and reproduce. The modified Alvarado score is widely used in emergency services. The Raja Isteri Pengiran Anak Saleha Appendicitis (RIPASA) score was formulated in 2010 and has greater sensitivity and specificity. The aim of our article was to compare the usefulness of modified RIPASA score and Alvarado score in the diagnosis of patients with abdominal pain and suspected acute appendicitis.Methods: A prospective study was undertaken among 100 cases presenting with signs and symptoms suggestive of acute appendicitis, conducted at the Narayana medical college hospital, Nellore. The questionnaires used for the evaluation process were applied to the patients suspected of having appendicitis.Results: A total of 100 patients, 95% underwent laparoscopic procedure. The cut-off threshold point of the Alvarado score was set at 7.0, which yielded a sensitivity of 65% and a specificity of 52%. The positive predictive value was 65%. The cut-off threshold point of the modified RIPASA score was set at 7.5, which yielded 90% sensitivity and 72% specificity. The positive predictive value was 89% and the NPV was 30%.Conclusions: On comparing both the scores, sensitivity and specificity was higher for modified RIPASA score. The positive predictive value was higher for the Alvarado and negative predictive value was higher for RIPASA score. Bothe p values were statistically significant.
