Implication

Observational study reveals modified CT severity index correlates better with clinical outcomes than standard staging, suggesting superior prognostic utility.

Key Points

To evaluate the correlation with clinical outcomes and interobserver agreement of a modified CT severity index compared to the traditional index in acute pancreatitis.
Retrospective review of 66 patients (out of 266 consecutive cases) who underwent contrast-enhanced MDCT within 1 week of symptom onset.
Three blinded radiologists independently graded disease severity using both the traditional and modified CT severity indices, the latter incorporating simplified inflammation/necrosis scoring and extrapancreatic complications.
Correlations with length of stay, intervention, infection, organ failure, and death were analyzed using Wilcoxon's rank sum and Fisher's exact tests, with kappa statistics for agreement.
The modified index demonstrated stronger correlations with the need for intervention (10/66; p=0.0112 vs p=0.0324) and infection risk (21/66; p<1e-10 vs p<1e-04) compared to the standard index.
Significant correlation with the development of organ failure (9/66 patients) was achieved exclusively by the modified index (p=0.0024) and missed by the standard scoring system (p=0.0513).
Interobserver agreement remained strong and comparable across both systems, with kappa values ranging from 0.71–0.85 for the modified index and 0.63–0.86 for the traditional index.
