HAPS (Harmless AP Score) in Determining Poor Prognosis in AP

Objective: Acute pancreatitis (AP) is a common disease of the gastrointestinal tract. Gallstones are the most common cause of AP etiology. Most prognosis scoring systems are non-practical in emergency departments (EDs). Harmless acute pancreatitis score (HAPS) is a scoring system that is easily used for detecting non-severe AP (SAP).
Material and Methods: In this study, patients aged >18 years and with International Classification of Diseases code K85 were retrospectively reviewed. After excluding trauma, recurrent pancreatitis, and cancer, 150 patients were included in the study. First, all patients were divided into two groups; HAPS0 and HAPS+. Radiological examination, necrosis, need for intensive care unit, mortality rates, and hospitalization durations of HAPS0 and HAPS+ were compared. Then, we calculated the HAPS and Ranson score (RS) for all patients and compared their odds ratio (OR).
Results: Of all patients, 58.5% were male. Biliary pancreatitis was observed in 72% of HAPS0 patients and 66.2% of HAPS+ patients. There was no inhospital mortality in the HAPS0 group. ORs were 4.229 and 0.885 for HAPS and the RS, respectively.
Conclusion: HAPS can be useful for discriminating between non-severe and SAP at the ED.
