"Investigating Why Clinicians Deviate from Standards of Care: Liberating Patients from Mechanical Ventilation in the ICU"

Bibliographic Information

• Research Area: Health Informatics and Human-Computer Interaction (HCI)
• Keywords: Medical care, field study, standardized care pathways, protocol adherence, mechanical ventilation patient care

Research Background and Problem Statement

• Identified Issues or Challenges:
  • Although clinical practice guidelines and care pathways like the "Wake Up and Breathe (WUB) Protocol" have been proven to significantly improve the condition of mechanically ventilated patients, their implementation in complex real-world clinical environments falls far short of the outcomes achieved in standardized studies. This is particularly evident in intensive care units (ICUs), where deviations from guidelines by healthcare professionals are frequent.
  • Current research primarily attributes such deviations to resistance or lack of awareness among healthcare professionals, overlooking the complexity and uncertainty inherent in clinical practice.
• Significance of the Problem:
  • Timely liberation of comatose and mechanically ventilated patients is critical for reducing pneumonia, cardiopulmonary damage, postoperative complications, and mortality rates.
  • Post-pandemic, the surge in mechanically ventilated cases in ICUs highlights the urgent need for the efficient implementation of standardized measures.
• Research Motivation and Related Work:
  • Existing literature predominantly explains healthcare professionals' behavior through psychological or behavioral analyses, with limited focus on how technology can enhance protocol adherence.
  • Research in the HCI field has introduced methods to support collaboration and information visualization but has yet to delve deeply into how to facilitate complex team collaboration for implementing standardized protocols.

Solution

• Proposed Solution:
  • Using a combination of field studies, interviews, and speculative design, this research aims to uncover the complex factors hindering the execution of the "Wake Up and Breathe" protocol and to clarify how uncertainty impacts healthcare professionals' prioritization of tasks.
  • Proposes a series of technological design improvements, including tools for patient eligibility assessment, clinical pathway support, and team collaboration.
• Innovative Aspects:
  • Highlights the critical role of technological systems in reducing uncertainty, improving team collaboration efficiency, and supporting clinical protocol adherence.
  • Redefines "protocol non-adherence" as a systemic issue rather than merely a behavioral problem among healthcare professionals.
• Implementation Steps and Techniques:
  • Field Observation: Conducted 47 hours of on-site tracking of ICU workflows, documenting collaboration methods among different roles through note-taking.
  • Semi-Structured Interviews: Explored the work patterns of nurses and respiratory therapists (RTs), sources of uncertainty, and their needs for technological support.
  • Group Interviews: Consolidated and validated feedback, integrating perspectives on cross-role collaboration.
  • Data Analysis: Employed affinity diagrams and service blueprinting to analyze care processes and further extracted key insights through thematic analysis.

Research Findings

• Specific Findings:
  • Identified key barriers to protocol adherence, including uncertainty in patient eligibility assessment, ambiguity in scheduling collaborative tasks, and individual differences in guideline interpretation.
  • Using a service blueprint, the execution process of "Wake Up and Breathe" was clearly divided into three stages—eligibility assessment, execution process, and care decision-making—each marked by significant uncertainty.
  • Proposed opportunities for technological support, such as predictive algorithms or patient eligibility dashboards, to alleviate the cognitive load on healthcare professionals when prioritizing tasks.
• Advantages Compared to Existing Solutions:
  • Goes beyond focusing on individual task completion by addressing how to support cross-role, multi-patient care from the perspectives of team collaboration and information integration.
  • Clarifies how artificial intelligence can be leveraged to enhance the personalization and dynamic adaptation of clinical practice guidelines.
• Experimental or Evaluation Results:
  • Field observations and interviews revealed shortcomings in existing technologies (e.g., electronic medical record systems), such as the lack of intelligent patient eligibility assessment, pathway visualization guidance, and shared coordination functions for teams.
  • Specific pain points included information silos among healthcare professionals, unclear task prioritization, and system designs that fail to document dynamic operations.
• Limitations and Future Directions:
  • The study's scope was limited, as it did not include perspectives from physicians, patients, or family members.
  • Future work should explore how technology can be integrated into real-world workflows and how to design systems suitable for diverse global healthcare environments.
  • Proposes AI-generated interaction designs to address team coordination issues while considering the ethical and application risks of introducing new technologies.

Conclusion

The study redefines the issue of "protocol non-adherence," shifting the perspective from a purely behavioral problem among healthcare professionals to a systemic and technological challenge. It suggests that technological design should assist healthcare professionals in simplifying decision-making processes and promoting best practices in team collaboration. These findings are not only applicable to ICUs but can also be extended to broader healthcare domains, emphasizing the potential of HCI in optimizing technological systems within complex medical environments.
