Combining image features, case descriptions and UMLS concepts to improve retrieval of medical images.
This paper evaluates a system, UBMedTIRS, for retrieval of medical images. The system uses a combination of image and text features as well as mapping of free text to UMLS concepts. ⋯ Our experimental results indicate that the proposed approach yields significant improvements in retrieval performance. Our system performs 156% above the GIFT system and 42% above the text retrieval system.

The Advanced Health and Disaster Aid Network (AID-N) project seeks to identify unmet needs of emergency response teams in the Washington, DC area during mass casualty incidents and conduct feasibility tests of technology-based solutions. The decentralized electronic triage and sensing system uses low power, electronic triage sensors to monitor the vital signs of patients and provide location tracking capabilities. ⋯ A field study demonstrates the process of current emergency procedures and the design implications of the prototype. This field study, along with the hardware and software architecture of the electronic triage system, lay the foundation for a reliable, decentralized sensor deployment that will continuously extend network coverage during a mass casualty incident.

Predicting hospital admission in a pediatric Emergency Department using an Artificial Neural Network.
Hospital admission delays in the Emergency Department (ED) reduce capacity and contribute to the ED's diversion problem. We evaluated the accuracy of an Artificial Neural Network for the early prediction of hospital admission using data from 43,077 pediatric ED encounters. ⋯ The area under the receiver operating characteristic curve was 0.897 (95% CI: 0.887-0.896). The instrument demonstrated high accuracy and may be used to alert clinicians to initiate admission processes earlier during a patient's ED encounter.

The complex work processes and communication patterns exhibited in Emergency Medicine may be effectively managed through the use of information technology. These tools must be evaluated within the work environment to understand their effects on work flow, information flow, and patient safety. In this study the efficiency of the Emergency Department triage process was evaluated pre- and post- implementation of a computerized triage system. Time-and-motion analyses revealed no changes in triage documentation time; however, the duration of interruptions and the number of tasks decreased significantly.

Clinicians recognize value of patient review of their electronic health record data.
Increasing patient demands for convenient access to their own health care information has led to the development of "patient portals" that allow limited patient access to ambulatory electronic health records (EHR). Little is known about clinicians attitudes towards this new model of health care. In our study, we collected baseline information about primary care providers (PCP) usage of a secure, web-based patient portal linked to the ambulatory EHR. We also assessed providers initial perceptions of these technologies as facilitators of patient-provider communications and the potential for these tools to improve quality of outpatient care.
