Highlight
The RIPASA score demonstrated higher sensitivity (94.6%) and better overall diagnostic discrimination (AUC 0.921) compared to the Modified Alvarado Score (MAS) in an Indian tertiary care setting.
Modified Alvarado Score showed higher specificity (83.3%) than RIPASA (66.7%), implying fewer false positives but more missed cases.
The study involved 62 patients undergoing appendectomy, with histopathological examination (HPE) as the diagnostic gold standard.
RIPASA’s improved diagnostic performance suggests its utility in high-prevalence Asian populations where advanced imaging is not routinely accessible.
