Smart Patient Care Systems Development in Shock Trauma

Principal Investigator: Colin Mackenzie  

Collection of information from the pulse oximeter (a sticky bandage placed on the finger or forehead that measures blood oxygen levels) is used in all patients admitted to the Shock Trauma Center. The pulse oximeter will be developed into a smart patient care system, with funding from the US Air Force. The smart patient care system will be used to identify patients who need emergency things done (opening of the airway, blood transfusion, heart massage etc) to prevent them dying. The development of the new smart pulse oximeter system will use training of intelligent computer software to predict the need for emergency actions and improve what the existing Food and Drug Administration (FDA) approved pulse oximeter can do. The training of the software will be done by using the vital signs (blood pressure, heart rate, pulse oximeter and heart signals using ‘stick-on’ (no needles) equipment) to progressively make the computer software recognize patterns of information from the pulse oximter. To make the pulse oximeter system smart, the information about continuous changes in pulse oximeter and other signs gathered from Shock Trauma patients during the first hour after they are admitted (when a lot of these emergency actions are taken to save lives) will be linked to the need for actions to prevent breathing, heart and shock problems.

This information is also being provided in paper copy to Shock Trauma patients.

Large Scale Collaboration in Critical Environments

National Science Foundation (Award Information: IIS-0325087)
Principal Investigator: Yan Xiao

Organizations operating in critical environments, such as hospitals and security agencies, have evolved into team-based, quasi-decentralized structures. Safety, efficiency, and quality performance in these organizations depend on the ability of the organization to support large scale collaboration-real time coordination across teams, tasks, and resources in a dynamic and risk-prone environment. This research begins to tackle problems of coordination in large-scale collaboration through field research in a trauma center, technology development of mobile devices for real time coordination, and laboratory studies to understand coordination across teams, people, and resources.

The research aims to develop a theory of trajectory management and management tools in large-scale collaboration and practical solutions to cross-team coordination. Researchers from University of Maryland Medical School, Carnegie Mellon University, and University of Arizona will collaborate on this research. This project will improve theory in organization science, increase understanding of how to exploit new information technology in critical environments, and improve coordination in hospitals and other vital organizations.

Multimedia-Enhanced Emergency Medical Procedure Checklist

NASA (Award information)
Principal investigator: F. Jacob Seagull

This research is a joint effort between the University of Maryland Human Factors Research Program (UM-HFRP), University of Utah, and Johnson Space Center's Usability Testing and Analysis Facility (NASA-UTAF). It will focus on the clinical capabilities for responding to medical emergencies, using EMPC protocols for Advanced Trauma Life Support (ATLS) as a testing task model for such an effort. The existing EMPC will be enhanced through the development of high- and low-resolution multimedia-supported computerized checklists to enhanced clinical capabilities. There are ongoing collaborative efforts between UM-HFRP and NASA JSC-UTAF. The University of Maryland and Utah have extensive experience in the use of multimedia to support medical performance, and NASA JSC-UTAF has investigated many aspects of the paper-based EMPC for other usability issues and works closely with the NASA medical community.

Leadership: Enhancing team adaptability in dynamic settings

Army Research Institute
Principal Investigator: Yan Xiao (Project PI: Katherine Klein Wharton School of Business)

We propose a 32-month research program designed to illuminate the influence of individual differences, team characteristics, and adaptive leadership on individual and team performance within a dynamic work environment. Using qualitative and quantitative methods, we will refine and test our conceptual model in a real-life, dynamic work setting: the Maryland Shock Trauma Center (STC). STC is the hub of Maryland's system of emergency trauma care, treating over 6,000 victims of traumatic injury each year. Medical residents in the STC work in cross-functional teams of varying composition to treat patients who arrive at unpredictable times with uncertain diagnoses. Like soldiers in the Army’s Objective Force, residents must perform adaptively as they face highly unpredictable, uncertain, and urgent problems whose resolution literally has life-or-death consequences. We will complement the research realism of STC data collection with the research rigor of experimentation in the Michigan State University TEAMSim Laboratory, a dynamic, PC-based, radar tracking simulation designed for the study of individual and team adaptive performance.

Universal Access for Situational Induced Impairments

National Science Foundation (Award Information)
Principal Investigator: Yan Xiao (Project PI: Andrew Sears of UMBC)

The long term goal of this research is to address the issues involved in developing effective computer systems for individuals experiencing situationally-induced impairments. Like disability-induced impairments (DII), situationally-induced impairments (SII) exist when the physical, cognitive, or perceptual demands placed on the user exceed their abilities. Unlike DII, SII are a result of the environments in which the work is being performed or the tasks in which the user is engaged. For example, paramedics must complete forms while providing medical care during ambulance-based patient transfers. The ambulance is moving, there is no stable surface on which to place the device being used to complete the forms, and the paramedic’s hands, eyes, and ears are often busy providing medical care. As a result, paramedics experience a variety of situationally-induced impairments while performing job related tasks.

The broad impact of this work is highlighted by the rapid diffusion of mobile computing technologies. As mobile computing becomes more pervasive, users enjoy increased flexibility in terms of where and when they record, retrieve, and transmit information. At the same time, the conditions under which these devices are used are becoming more variable, less predictable, and in many situations less hospitable. With increasing frequency, computers are being used when lighting is poor, noise is unpredictable, or when the user is on the move (e.g., walking, driving a vehicle). In addition, mobile devices also result in users interrupting an ongoing activities to perform secondary computer-based tasks. Individuals are replying to text pages during meetings, doctors are reviewing operating room schedules while interacting with patients, and individuals are retrieving directions from their in-vehicle navigation system while driving.

Refined Training Tools for Medical Readiness

US Air Force
Principal Investigator: Colin Mackinzie (Project PI: Eileen Entin of Aptima)

This project develops and tests a distributed teamwork skills training program for co-located or distributed teams performing complex, highly interdependent tasks that require overlapping expertise and shared knowledge, flexibility, and the capability for rapid organization and deployment to respond quickly to a changing situation. Our goal is to develop and demonstrate a training approach that uses advanced distance learning technology to provide portable training to small, flexible, quickly reconfigured, rapidly deployed military teams. The program is a web-enabled, scenario-based teamwork skills training program comprised of: information about and examples of teamwork skills; scenario-based training exercises that provide practice in teamwork skills; guidelines for team-conducted exercise debriefings that do not require the presence of a training instructor; and a leader’s manual that helps team leaders to conduct web-based training sessions. The version we are currently developing is focused on physicians under training (fellows and residents) working in an academic trauma center.
