Information Technology

The research is driven by the overall goal of developing new technology to facilitate data rich information transfers. Research projects include mobile telemedicine applications for rapid assessment of stroke patients en route to hospitals, high speed video conferencing networks for specialty stroke care at rural hospitals, field data collection of patient vital signs and images for trauma and mass casualty care, and intra-hospital communication systems using video-audio-vital sign data. The systems developed were featured in news broadcast by public and commercial television stations.

Advanced video technology to support operating room coordination.

Peter Hu and his colleagues described an innovative design solution in 2006 issue of Surgical Innovation that maximizes information while ensures patient and staff confidentiality. The staff through the technology (VideoBoard) can obtain real-time OR video at different level of clarity for improved situation awareness. VideoBoard has become an operations necessity as demanded by clinicians. [Sponsored by DoD and NSF]

Supporting multi-disciplinary rounds with information technology

Ayse Gurses and Yan Xiao systematically reviewed the literature on how information tools are used to support care coordination in an 2006 issue of Journal of American Medical Informatics Association. Important functions of information tools to support care coordination were identified as information organization, team communication, and work management, which could be achieved through automatic extraction from clinical information systems, displays and printouts in condensed forms, at-a-glance representations of the care unit, and storing work-process information ephemerally.

Automated patient in/out status display supporting OR coordination

Yan Xiao and his colleagues described an algorithm in 2005 issue of Anesthesia & Analgesia to identify remotely whether a patient is in the OR. The algorithm was implemented at a trauma OR (6 room) and a general OR (19 room) and has been used since 2002 in operations to provide real-time, automated, patient in and out time information. The accuracy of the algorithm was shown to be equivalent to human data collection (about 5 minutes). [Sponsored by DoD and NSF]


What do they use to call a trauma team together?

Yan Xiao and colleagues analyzed a national survey of trauma centers on the use communication technologies in assembling trauma teams in a 2006 issue of Journal of Emergency Medicine. Manual or computerized pagers were number one choice (57% and 37%, respectively). Cellular phones have become a medium of choice between field and hospital care providers. Penetration of newer methods of communications (e.g., text messages and image transfers) was rare. [Sponsored by NSF]

Care coordination system by paper, whiteboards, and computers.

Yan Xiao and Jake Seagull reported their insight of how computers, paper documents, and whiteboards were used in conjunction to support care coordination in an upcoming issue of International Journal of Medical Informatics. When compared with papers and whiteboards, current designs of computerized system are rigid and difficult for care providers to adapt for ever changing communication patterns.
