The potential of training to increase acceptance and use of computerized decision support systems for medical diagnosis.

OBJECTIVE: The goals of this study were to understand the reasons underlying the limited use of medical decision-support tools and to explore the potential of a computer-based tutorial to mitigate barriers to use. BACKGROUND: Medical decision-support tools such the Acute Cardiac Ischemia Time-Insensitive Predictive Instrument (ACI-TIPI) have demonstrated statistical validity and clinical impact for patient safety but have seen limited adoption and use. METHODS: The study developed a brief Web-based "demystifying" ACI-TIPI tutorial employing case-based training and evaluated the effectiveness of that tutorial in changing self-reported attitudes and behaviors. RESULTS: Clinicians using the tutorial reported greater understanding of how to use the ACI-TIPI score appropriately and increased confidence in the score. Case studies in the tutorial that provided examples of how to use the score for actual cases were rated as especially helpful. CONCLUSION: This study suggests that a primary barrier to the use of statistical decision support tools for patient diagnosis is lack of training or experience in combining a population-based numerical risk score with other diagnostic information about the individual patient's case that is not considered in that score. The results of this study indicate that there is a potential for a relatively brief tutorial to increase acceptance and use of decision support tools for medical diagnosis. APPLICATION: These findings have the potential for the identification of methods to help clinicians learn how to use statistical and probabilistic information to better assess risk and to promote integration of decision support tools into medical decision making for improvement of patient safety.

Gestalt operating room display design for perioperative team situation awareness.

The perioperative environment is a complex, high risk environment that requires real-time coordination by all perioperative team members and accurate, up-to-date information for situation assessment and decision-making. There is the need for a "Gestalt" holistic awareness of the perioperative environment to enable synthesis and contextualization of the salient information such as: patient information, case and procedure information, staff information, operative site view, physiological data, resource availability. One potential approach is to augment the medical toolkit with a large screen wall display that integrates and makes accessible information that currently resides in different data systems and care providers. The objectives are to promote safe workflows, team coordination and communication, and to enable diagnosis, anticipation of events, and information flow from upstream to downstream care providers. We used the human factors engineering design process to design and develop a display that provides a common operational picture for shared virtual perioperative team situation awareness to enhance patient safety.

Integrating surgical robots into the next medical toolkit.

Surgical robots hold much promise for revolutionizing the field of surgery and improving surgical care. However, despite the potential advantages they offer, there are multiple barriers to adoption and integration into practice that may prevent these systems from realizing their full potential benefit. This study elucidated some of the most salient considerations that need to be addressed for integration of new technologies such as robotic systems into the operating room of the future as it evolves into a complex system of systems. We conducted in-depth interviews with operating room team members and other stakeholders to identify potential barriers in areas of workflow, teamwork, training, clinical acceptance, and human-system interaction. The findings of this study will inform an approach for the design and integration of robotics and related computer-assisted technologies into the next medical toolkit for "computer-enhanced surgery" to improve patient safety and healthcare quality.

Developing a simulation-based training program for medical first responders.

A major stumbling block for widespread incorporation of simulators into EMT training includes the limited availability of curricula infrastructure linking the key components of skills, scenarios, and measures as well as the expertise required to run such programs. To meet these needs we are developing a training program for first responders that uses mannequin-based simulator technology effectively to fill the identified training need for valid meaningful scenarios that can be integrated into the curriculum and are applicable for a variety of EMT skill levels. The program will provide detailed scenarios, instructions for administering the program, and measures for performance feedback. Each scenario will exercise a combination of task work and cognitive skills and the set of scenarios will span all of the higher-level skills that have been identified as benefiting from targeted training.

Usability factors in the organization and display of disparate information sources in the operative environment.

The integration and presentation of information from a number of disparate sources in the operative environment raises a number of usability and human factors challenges. Through a collaborative effort, a display combining persistent and dynamically switching panes provides a rich source of information to help orient team members, provide indications of case progress, and organize information into stage-based tabbed panes. This provides maximal flexibility within visibility and usability constraints.

Integration of hospital information systems, operative and peri-operative information systems, and operative equipment into a single information display.

The integration of disparate information systems in the operative environment allows access to information that is typically unseen or unused. Through a collaborative effort, a variety of information systems and surgical equipment are being integrated. This provides improved context-sensitive information display and decision support and improved access to information to improve workflow, safety and visualization of information that was previously unattainable.
