Patient Handover in the Emergency Department Is Not Just a Point Event: Insights for Designing Information Support Tools

Research Background and Issues

• Issues and Challenges: In emergency departments (EDs), the patient handover process is complex and dynamic, with information often being fragmented, incomplete, or uncertain. Existing tools such as Electronic Health Records (EHRs) and standardized handover protocols (ISBAR) aim to improve information exchange processes but often fall short in fast-paced environments, failing to fully address the diverse needs of EDs.
• Significance: Information handover in emergency departments directly impacts patient safety and subsequent treatment decisions. Improper information handling can lead to communication errors, affecting patient outcomes. In such high-pressure environments, information support tools become particularly critical, significantly enhancing work efficiency and patient safety.
• Research Motivation and Related Work: The authors identify the importance of handovers as a dynamic, multidisciplinary collaborative process through existing literature and point out that previous research has focused more on the design of collaboration tools, with less attention paid to the uncertainty, specificity, and ad hoc nature of information work.

Proposed Solution

• Proposed Method or Solution: The study introduces a design perspective centered on "information relativity" to guide the development of information support tools. Information relativity encompasses uncertainty, specificity, incompleteness, and temporality.
• Innovations:
  • Viewing handovers as dynamic, continuous processes rather than single-point events.
  • Emphasizing the adaptive decision-making process of physicians when handling uncertain and incomplete information during handovers.
  • Proposing a new design framework, "information relativity," to capture the rapidly changing characteristics of information in ED environments.
• Implementation Steps:
  • The study design includes 40 field observations totaling 75 hours, along with recordings of 17 physician handovers and interviews.
  • Inductive thematic analysis was employed to naturally document the main actions and information processing workflows during handovers.
  • The "information relativity" design framework was proposed to provide support and recommendations for designing information tools.

Research Outcomes

• Specific Findings:
  • Demonstrated that handovers are not merely information transmission events but rely on physicians actively anticipating needs, managing dynamic and uncertain information, and planning contingency strategies as part of a continuous process.
  • Extracted four dimensions for improving the design of information support tools—uncertainty, specificity, incompleteness, and temporality.
• Advantages Compared to Existing Solutions:
  • Overcomes the limitations of traditional handover frameworks and tools (e.g., ISBAR) by focusing more on dynamic information processing and physicians’ adaptive working methods.
  • Provides a comprehensive and flexible approach to handling complex information in EDs while meeting the dynamic needs of the environment.
• Experimental or Evaluation Results:
  • Field observations revealed that the handover process heavily relies on physicians’ ability to synthesize fragmented information and collaborate in real-time through multiple channels.
  • The proposed framework makes significant contributions to improving the adaptability and practicality of tool design.
• Limitations and Future Directions:
  • Limitations: The study currently focuses on the physician handover process, without in-depth exploration of the roles of nurses and other team members; research on specific interaction methods for information tools remains preliminary.
  • Future Directions: Expand the scope of analysis to include interdepartmental or multidisciplinary team handovers and explore how contemporary technologies (e.g., augmented reality and AI) can better support the dynamic information needs of EDs.

By reframing handovers from traditional single events to dynamic, relative processes of information work, this study provides new insights for the design of information tools, emphasizing flexibility and adaptability as critical factors in supporting ED operations. In the future, further exploration of the "information relativity" principles in clinical environments will open new pathways for improving the safety and efficiency of patient handovers.
