Principles for Profiling Healthcare Data Communication Standards

July 22, 2013
Author(s)
Robert D. Snelick
Healthcare organizations often have many proprietary heterogeneous information systems that must exchange data reliably. Seamlessly sharing information among systems is complex. The widely adopted HL7 version 2 messaging standard has helped the process of

Overview of the TREC 2012 Medical Records Track

June 28, 2013
Author(s)
Ellen M. Voorhees, William Hersh
The TREC Medical Records track fosters research that allows electronic health records to be retrieved based on the semantic content of free-text fields. The ability to find records by matching semantic content will enhance clinical care and support the

Distributed Coverage Optimization in a Network of Static and Mobile Sensors

June 17, 2013
Author(s)
Kamran Sayrafian, Hamid Mahboubi, Jalal Habibi, Amir Aghdam
This paper proposes efficient schemes to increase sensing coverage in a network composed of both mobile and static sensors. The proposed deployment techniques properly assign a virtual weight to every point in the sensing field, based on the information

A Dynamic Human Body Computational Phantom for RF Propagation Study

May 20, 2013
Author(s)
John G. Hagedorn, Kamran Sayrafian, Judith E. Terrill
Recent advances in micro-electronics technology to build small radio-enabled implantable and wearable medical sensors have sparked considerable interest in further understanding the characteristics of radio frequency propagation inside the human body. As

Enhancing Electronic Health Record Usability in Pediatric Patient Care: A Scenario-Based Approach

March 20, 2013
Author(s)
Emily S. Patterson, Jiajie Zhang, Patricia Abbott, Michael C. Gibbons, Svetlana Z. Lowry, Matthew T. Quinn, Mala Ramaiah, David Brick
Adoption of electronic health record (EHR) systems in hospitals and physician practices is accelerating. Usability of EHRs has been identified as an important factor impacting patient safety and EHR adoption rate for both adult and pediatric care providers

Virtual Reality Platform to Study RF Propagation in Body Area Networks

December 2, 2012
Author(s)
Kamran Sayrafian, John G. Hagedorn, Wen-Bin Yang, Judith E. Terrill
Design of efficient wireless communication protocols for body area networks requires in-depth understanding of the propagation media i.e. the human body. As obtaining large amount of data for many scenarios and use-cases via physical experiment is either

Testing the Nations Health care Information Infrastructure

November 10, 2012
Author(s)
Kevin G. Brady, Ram D. Sriram, Bettijoyce B. Lide, Kathleen M. Roberts
According to a report by the Center for Medicare and Medicaid Services [CMS] (http://www.cms.gov), the United States spent nearly $2.6 trillion dollars on health care in 2010. It is estimated that this will nearly double by the end of this decade. This is

Interference Mitigation Using Adaptive Schemes in Body Area Networks

September 30, 2012
Author(s)
Wen-Bin Yang, Kamran Sayrafian
Considering the medical nature of the information carried in Body Area Networks (BAN), interference from coexisting wireless networks or even other nearby BANs could create serious problems on their operational reliability. As practical implementation of

Radiation Pattern of an UWB Wearable Antenna: A Preliminary Study

September 24, 2012
Author(s)
Wen-Bin Yang, Kamran Sayrafian
Inhomogeneity of the propagation medium in body area networks could have a great impact on the sensor node's antenna characteristics. This in turn could affect the quality of the communication links unless the impact of the human body has been properly
