Abstract
BACKGROUND

Acute pancreatitis (AP) is a common surgical condition, with severe AP (SAP) potentially lethal. Many prognostic indices, including; acute physiology and chronic health evaluation II score (APACHE II), bedside index of severity in acute pancreatitis (BISAP), Glasgow score, harmless acute pancreatitis score (HAPS), Ranson’s score, and sequential organ failure assessment (SOFA) evaluate AP severity and predict mortality.

AIM

To evaluate these indices' utility in predicting severity, intensive care unit (ICU) admission, and mortality.

METHODS

A retrospective analysis of 653 patients with AP from July 2009 to September 2016 was performed. The demographic, clinical profile, and patient outcomes were collected. SAP was defined as per the revised Atlanta classification. Values for APACHE II score, BISAP, HAPS, and SOFA within 24 h of admission were retrospectively obtained based on laboratory results and patient evaluation recorded on a secure hospital-based online electronic platform. Data with < 10% missing data was imputed via mean substitution. Other patient information such as demographics, disease etiology, and patient outcomes were also derived from electronic medical records.

RESULTS

The mean age was 58.7 ± 17.5 years, with 58.7% males. Gallstones (n = 404, 61.9%), alcohol (n = 38, 5.8%), and hypertriglyceridemia (n = 19, 2.9%) were more common aetiologies. 81 (12.4%) patients developed SAP, 20 (3.1%) required ICU admission, and 12 (1.8%) deaths were attributed to SAP. Ranson’s score and APACHE-II demonstrated the highest sensitivity in predicting SAP (92.6%, 80.2% respectively), ICU admission (100%), and mortality (100%). While SOFA and BISAP demonstrated lowest sensitivity in predicting SAP (13.6%, 24.7% respectively), ICU admission (40.0%, 25.0% respectively) and mortality (50.0%, 25.5% respectively). However, SOFA demonstrated the highest specificity in predicting SAP (99.7%), ICU admission (99.2%), and mortality (98.9%). SOFA demonstrated the highest positive predictive value, positive likelihood ratio, diagnostic odds ratio, and overall accuracy in predicting SAP, ICU admission, and mortality. SOFA and Ranson’s score demonstrated the highest area under receiver-operator curves at 48 h in predicting SAP (0.966, 0.857 respectively), ICU admission (0.943, 0.946 respectively), and mortality (0.968, 0.917 respectively).

CONCLUSION

The SOFA and 48-h Ranson’s scores accurately predict severity, ICU admission, and mortality in AP, with more favorable statistics for the SOFA score.

Core Tip: Acute pancreatitis is a common surgical emergency requiring quick evaluation of its severity to guide further management principles. Both the sequential organ failure assessment (SOFA) and 48-h Ranson scores accurately predict severity, intensive care unit admission, and mortality in acute pancreatitis (AP), with more favorable statistics for the SOFA score. Simple bedside scores such as bedside index of severity in AP and harmless AP score are practical and straightforward tests to screen out mild disease at the onset, allowing physicians to preferentially allocate resources for severe AP patients.
