Publication Info

• Topic area: Clinician-patient communication of numerical health data
• Keywords: Personal health data, clinician-patient communication, health numeracy, patient-centered care, shared decision making, communication aids, data visualization, healthcare technology, HCI, medical ethics

Background and Problem

• Problem / challenge: Clinicians face significant challenges in effectively communicating complex numerical health data to patients, compounded by the increasing volume and complexity of medical data and the diverse needs of patients.
• Significance: Clear communication of health data is essential for patient-centered care, shared decision-making, and informed consent, which are critical for improving patient outcomes and satisfaction.
• Motivation and related work: Prior research has focused on patient perspectives or public health communication, but little attention has been given to how clinicians communicate numerical data during individual consultations. Existing communication aids often lack personalization and fail to address the unique challenges of explaining complex numerical concepts.

Solution

• Proposed approach: The paper identifies 57 communication techniques used by clinicians, categorizes them into strategies and themes, and highlights 9 tensions in their application. It provides guidelines for designing communication aids aligned with clinical practice.
• Novelty:
  1. Comprehensive identification and categorization of 57 communication techniques used by clinicians.
  2. Definition of 9 tensions that arise when applying these techniques in practice.
  3. Development of 6 design guidelines for creating effective clinician-patient communication aids.
  4. Focus on the clinician's perspective, complementing existing patient-centered research.
• Procedure and key techniques:
  • Conducted 19 semi-structured interviews with clinicians across specialties.
  • Used Template Analysis to identify and categorize techniques into three themes: data-centered, patient-centered, and clinician-centered.
  • Defined 9 tensions based on clinician experiences and challenges.
  • Proposed 6 design guidelines to address these tensions and improve communication aids.

Results

• Concrete findings:
  • Identified 57 communication techniques grouped into 11 strategies and 3 themes: data-centered (e.g., structuring information, displaying data), patient-centered (e.g., promoting understanding, building trust), and clinician-centered (e.g., learning and reflection, collaboration).
  • Defined 9 tensions, including "patient expectations vs. realistic practice," "data complexity vs. pacing communication," and "low clinician numeracy vs. increasingly complex data."
• Advantage over baselines: Provides a detailed taxonomy of communication techniques and tensions, offering actionable insights for designing communication aids that align with real-world clinical practice.
• Experiments / evaluation: Interviews with 19 clinicians from diverse specialties and experience levels; analysis of their techniques and challenges in communicating numerical health data.
• Limitations and future work:
  • Focused on clinicians in the UK NHS; findings may not generalize to other healthcare systems.
  • Limited sample size and lack of representation from certain specialties (e.g., pediatrics).
  • Did not include patient perspectives; future work could explore patient-clinician co-design and evaluate communication aids with diverse user groups.

Summary

This study examines how clinicians communicate complex numerical health data to patients, identifying 57 techniques and 9 tensions that arise in practice. By categorizing these techniques into data-centered, patient-centered, and clinician-centered themes, the paper provides a comprehensive framework for understanding current practices. The identified tensions highlight the challenges clinicians face, such as balancing data complexity with patient understanding and navigating ethical dilemmas in data disclosure. To address these challenges, the authors propose 6 design guidelines for creating effective communication aids that align with clinical practice. This work offers valuable insights for the HCI and healthcare communities, paving the way for more personalized and effective clinician-patient communication tools.
