Several steps that need to be followed to ensure better reporting and tracking of medical errors are presented. One of steps is to use improved electronic health records (EHR) user-interface designs that offer healthcare providers shorter learn-times, faster performance, and lower interface error rates. A second step should be agreements on user interface consistency and data interoperability among the 100-plus developers of EHR. Such guidelines for consistency and data sharing, common in other industries, would allow healthcare professionals who work at more than one location to do their jobs more efficiently and safely. Guidelines for user interfaces and public reporting of usability testing for errors would lay the foundation for changes in the way data is handled. The independent oversight panels, convened by healthcare providers, professional organizations, and government agencies, would specify improvements in information technologies and processes for software developers, hospitals, and labs.

Emergency exercises are an efficient approach for preventing serious damage and harm, including loss of life and property and a wide range of adverse social effects, during various public emergencies. Among various factors affecting the value of emergency exercises, including their design, development, conduct, evaluation, and improvement planning, this paper emphasizes the focal role of evacuees and their behavior. We address two concerns: What are the intrinsic reasons behind human behavior? How do we model and exhibit human behavior? We review studies investigating the mechanisms of psychological behavior and crowd evacuation animation. A comprehensive analysis of logical patterns of behavior and crowd evacuation is presented first. The interactive effects of information (objective and subjective), psychology (panic, small groups, and conflicting roles), and six kinds of behavior contribute to a more effective understanding of an emergency scene and assist in making scientific decisions. Based on these studies, a wide range of perspectives on crowd formation and evacuation animation models is summa- rized. Collision avoidance is underlined as a special topic. Finally, this paper highlights some of the technical challenges and key questions to be addressed by future developments in this rapidly developing field.
