Medical record keeping in the U.S is in a transition stage. The transformation from the 'old' paper medical charts to an Electronic Health Records (EHRs) is a $19 Billion endeavor that aims to optimize our healthcare system by enhancing physician performance, standardizing delivery of care and eventually improving patient outcomes. This conversion seeks to reduce communication barriers between clinicians, provide instant accessibility of medical information to patients and reduce the increasing national healthcare costs. Achieving these objectives requires EHRs to include functionality that helps clinicians manage clinical states, remember drug dosages or drug interactions and select the most effective treatment or test for a specific clinical scenarios.
