Introduction:

Acute pancreatitis continue to be a disease with significant morbidity and mortality. It is diagnosed by clinical criteria and the inflammatory process can lead to organ failure.

Objective:

This study compared the APACHE II and BISAP scales in organ failure development in patients with acute pancreatitis from a public hospital in Peru.

Methods:

A diagnostic test validation study was carried out. The medical records of patients hospitalized with the diagnosis of acute pancreatitis in the Internal Medicine service and the Intensive Care Unit were evaluated. The APACHE II and BISAP scales were applied, the ROC curve, sensitivity, specificity, positive and negative predictive value were calculated. SPSSv23 was used for statistical analysis.

Results:

146 patient records that met the inclusion criteria were evaluated. An area under the curve of 0.957 was obtained for BISAP and 0.996 for APACHE II. It had a sensitivity and specificity for APACHE II of 83% and 99%, for BISAP of 66% and 99%. The positive and negative predictive value for APACHE II is 83% and 99%, and for BISAP 80% and 98%.

Conclusion:

The APACHE II scale was superior to detect organ failure. It was determined that both scales have high specificity, the sensitivity being more significant in the BISAP scale.
