The article by Schwed et al1 compared a more recent cohort of patients with acute cholangitis (AC) at 1 of the 2 institutions (validation cohort) with a historical group of similar patients (derivation cohort). Their prior study of the derivation cohort identified 3 independent admission risk factors that predisposed to adverse outcomes in AC: white blood cell (WBC) count greater than 20 000 cells/µL (to convert to ×109 per liter, multiply by 0.001), total bilirubin level greater than 10 mg/dL (to convert to micromoles per liter, multiply by 17.104), and advanced age.2 The aim of the current study was to validate the criteria previously identified.
