At 48 Hours
Hct drop >10%

Ranson's Score:
0
–
–
Estimates mortality of patients with pancreatitis, based on initial and 48-hour lab values.
When to Use
Calculated on admission, and at 48 hours, to estimate mortality from pancreatitis.
Formula
Addition of the assigned points.
Management
Helps determine the disposition of the patient, with a higher score corresponding to a higher level of care.
More Information
Ranson's Criteria was developed in the 1970s to address pancreatitis mortality; however, it may over-estimate mortality given its study and development 30-40 years ago. The BISAP Score requires fewer patient variables and is likely just as accurate -- if not more so -- than Ranson's criteria for predicting adverse outcome in patients with acute pancreatitis.
