Health Evaluation" (APACHE II) score > 8 points predicts 11% to 18% mortality Hemorrhagic peritoneal fluid Obesity Indicators of organ failure Hypotension (SBP <90 mmHG) or tachycardia > 130 beat/min PO2 <60 mmHg Oliguria (<50 mL/h) or increasing BUN and creatinine Serum calcium < 1.90 mmol/L (<8.0 mg/dL) or serum albumin <33 g/L (<3.2.g/dL)> Balthazar score Developed in the early 1990s by Emil J. Balthazar et al., the Computed Tomography Severity Index (CTSI) is a grading system used to determine the severity of acute pancreatitis. The numerical CTSI has a maximum of ten points, and is the sum of the Balthazar grade points and pancreatic necrosis grade points: Balthazar grade Necrosis score CTSI's staging of acute pancreatitis severity has been shown by a number of studies to provide more accurate assessment than APACHE II, Ranson, and C-reactive protein (CRP) level. However, a few studies indicate that CTSI is not significantly associated with the prognosis of hospitalization in patients with pancreatic necrosis, nor is it an accurate predictor of AP severity. Glasgow score The Glasgow score is valid for both gallstone and alcohol induced pancreatitis, whereas the Ranson score is only for alcohol induced pancreatitis. If a patient scores 3 or more it indicates severe pancreatitis and the patient should be considered for transfer to ITU. It is scored through the mnemonic, PANCREAS: P - PaO2 <8kPa A - Age >55-years-old N - Neutrophilia: WCC >15x10(9)/L C - Calcium <2 mmol/L R - Renal function: Urea >16 mmol/L E - Enzymes: LDH >600iu/L; AST >200iu/L A - Albumin <32g/L (serum) S - Sugar: blood glucose >10 mmol/L BISAP score Predicts mortality risk in pancreatitis with fewer variables than Ranson's criteria. Data should be taken from the first 24 hours of the patient's evaluation. BUN >25 mg/dL (8.9 mmol/L) Abnormal mental status with a Glasgow coma score <15 Evidence of SIRS (systemic inflammatory response syndrome) Patient age >60 years old Imaging study reveals pleural effusion Patients with a score of zero had a mortality of less than one percent, whereas patients with a score of five had a mortality rate of 22 percent. In the validation cohort, the BISAP score had similar test performance characteristics for predicting mortality as the APACHE II score. As is a problem with many of the other scoring systems, the BISAP has not been validated for predicting outcomes such as length of hospital stay, need for ICU
