To the Editor: Using Ranson's criteria to forecast
outcome in patients with pancreatitis would indicate that a 56-year-old individual
with a glucose level of 201 mg/dL (11.2 mmol/L) and a white blood cell count
of 16.1 ×103/µL has the same risk for adverse outcome
as one who develops a PO2of less than 60 mm Hg, has a decrease
in hematocrit by 10%, and sequesters 6 L of abdominal fluid in 48 hours.1 I would call into question the validity of a scoring
system that equally weights these disparate factors.
