Abstract

A system and method of confirming administration of medication in a clinical trial is provided. The method comprises the steps of receiving information identifying a particular medication prescription regimen in accordance with the clinical trial, determining one or more procedures for administering such prescription regimen and identifying one or more activity sequences associated with such procedures. Activity sequences of actual administration of such prescription regimen are captured and then compared to the identified activity sequences to determine differences therebetween. A notice is provided if differences are determined.
