Johnson et al developed the APACHE-O score to evaluate patients with severe acute pancreatitis. The authors are from Southampton General Hospital and the University of Sheffield in England.
Patient selection: severe acute pancreatitis
Parameters measured during the first 24 hours after admission:
(1) APACHE II score
(2) obesity score derived from the body mass index (BMI)
body mass index =
= (body weight in kg) / ((body height in meters)^2)
Body Mass Index
26 to 30
APACHE-O score =
= (APACHE II score) + (obesity score)
• A score > 8 or > 9 can be used to identify a patient who will develop severe pancreatitis.
• A cutoff > 8 was 89% sensitive and 79% specific.
• A cutoff > 9 was 82% sensitive and 86% specific.
