MigraineTracker: Examining Patient Experiences with Goal-Directed Self-Tracking for a Chronic Health Condition

Paper Information

• Subject Area: Personal Health Informatics, Chronic Disease Management, Migraine Tracking Tool Design
• Keywords: Goal-Directed Tracking, Long-Term Tracking, Goal Evolution, Self-Tracking, Chronic Disease, Personal Informatics, Migraine

Research Background and Problem

• Identified Problems or Challenges:

  • Managing chronic conditions like migraines often relies on self-tracking, but existing tracking tools struggle to align with individual goals.
  • There is significant lack of support in deciding what to track, how to adjust tracking, and how to analyze and utilize collected data.
  • Current tools often embed default assumptions without adequately considering users' specific goals, leading to diminished value in long-term tracking.
  • Goal evolution is particularly critical in long-term tracking but lacks effective support.

• Importance of the Problem:

  • Managing chronic conditions (e.g., migraines) requires personalization and dynamic adjustments. A well-designed self-tracking tool is crucial for helping patients understand their condition, communicate with doctors, and take health-related actions.

• Research Motivation and Related Work:

  • In the goal-directed self-tracking framework proposed by Schroeder et al., explicitly expressing goals is believed to improve tracking experiences. However, it remains unclear whether these improvements extend to the stages of data collection, reflection, and action.
  • This study aims to fill this knowledge gap through long-term use by real patients.

Solution

• Proposed Method or Solution:

  • Designed and developed a goal-directed self-tracking application called MigraineTracker, which supports patients in explicitly expressing tracking goals related to migraine management.
  • Explored whether a personalized tracking tool can support the entire process of data collection, reflection, and action after patients establish their goals.

• Innovative Aspects of the Solution:

  • Emphasized user goal expression and personalized tracking settings to reduce data overload or irrelevant information interference.
  • Provided dynamic adjustment support based on patient goals, allowing different goals to exist in various tracking stages simultaneously.
  • Combined multi-goal management and personal informatics theories to support chronic disease management.

• Implementation Steps and Key Technologies:

  1. Tool Design and Goal Expression: Allowed users to choose from three major goal categories (monitoring, learning, predicting) and recommended tracking content based on the selected goals.
  2. Tracking Configuration and Flexibility: Offered tracking suggestions for symptoms, treatments, and potential triggers while supporting user customization.
  3. Data Input and Reminder Functionality: Supported daily, event-driven, and multi-goal tracking methods with flexible reminder settings.
  4. Data Review and Visualization: Enhanced user reflection and decision-making through goal-based summaries and visualizations.

Research Findings

• Specific Outcomes Achieved:

  • Patients expressed and adjusted multiple goals through the tool, aligning tracking more effectively with their needs.
  • Tracking significantly improved patients' understanding and self-management abilities, such as identifying specific triggers (e.g., stress or diet) or treatment effects.
  • Patients generated actionable insights based on their goals and communicated more effectively with their doctors.

• Advantages Compared to Existing Solutions:

  • Addressed the lack of goal support in other tools by enabling explicit goal expression for personalization and long-term use.
  • Provided flexible data input and diverse data models based on goals, guiding patients to track data efficiently and meaningfully.
  • Fully supported the tracking lifecycle from data recording to reflection and action, accommodating the complex needs of dynamic goal adjustments.

• Experiment or Evaluation Results:

  • A 12-month long-term deployment study involved 10 migraine patients and 3 doctors, with a total of 50 interviews conducted. Most patients found MigraineTracker highly usable, personalized, and were willing to use it long-term.
  • All participants reported gaining better insights than before and expressed a desire to continue using the tool, while also requesting additional feature support (e.g., more complex reports).

• Limitations and Future Directions:

  • Limitations: The current design still lacks sufficient support for goal adjustments and implicit relationships; flexibility in data processing and visualization needs improvement.
  • Future Directions:
    1. Explore more advanced support, such as automatic inference of relationships between goals.
    2. Introduce complex machine learning visualization models to uncover hard-to-detect data patterns.
    3. Support broader goal evolution, such as tracking support that integrates family or community resources.
    4. Further study doctor-patient collaboration paradigms to enhance doctors' effective use of patients' self-tracking data.

Conclusion

MigraineTracker demonstrates the significant potential of goal-directed self-tracking in chronic disease management, emphasizing the importance of explicit goal expression and personalized tool support. Future work should further expand the flexibility of goal customization, address complex data needs, and provide more effective support for patients.
