The goals of this audit were to: (1) validate preset adjudication criteria through an audit of appropriateness at four large academic hospitals; (2) identify variability in appropriateness across medical services, physician specialties or hospital locations; and (3) inform logistical or educational interventions that may reduce inappropriate use.<\/jats:p><\/jats:sec><jats:sec><jats:title>Materials and Methods<\/jats:title><jats:p>A chart review of two hundred patients receiving PLT transfusions was performed.
