This document discusses the principles of electronic medical record (EMR) usability. It defines usability as how effective, efficient and satisfying a system is for particular users to complete specific tasks in a given environment. The document outlines several usability principles including simplicity, consistency, minimizing cognitive load, and providing feedback. It describes methods for evaluating EMR usability, such as measuring efficiency, effectiveness and patient safety. The document recommends developing test scenarios and a five-star rating system to measure and improve EMR usability over time.
