Dr. Mia Lustria’s presentation on “Research Perspectives in Consumer Health Informatics and Measurement Issues” reviewed:
What is consumer health informatics?
- “The branch of medical informatics that analyses consumers’ needs for information; studies and implements methods of making information accessible to consumers; and models and integrates consumers’ preferences into medical information systems”
- Example: The Wellness Community
- Interdisciplinary field — draws from a variety of fields, and not just technology
Rationale for consumer health informatics
- Shift in emphasis from disease and treatment to health and wellness
- 80% of Americans have searched the Internet for health info
Characteristics of interactive technologies
- Messages can be both widely disseminated yet personalized
- Important attributes: multimodality and sensory vividness (example: ReMission — online game for young cancer patients); networkability and interactivity — building community and ability to get immediate feedback from experts; temporal flexibility — control the timing of your interactions; message tailoring capabilities — reach narrowly defined audiences and do so according to individual characteristics, which improves engagement
- But interactive technologies were at times superior and sometimes no better than other media
Measurement issues
- Not just reach but actually changing behavior
- Access issues — tested with literate populations; maybe not reaching people who need the most help
- Sometimes poorly designed, not linked with theory
- Measuring program engagement and outcomes, including engagement with the content; relatively low rate of long-term engagement in many Web-based programs; figure out what works and what doesn’t
- Using direct and unobtrusive methods (page visits, time on page, etc.), but those are not always easy; therefore oftentimes resort to online surveys, which rely on self-reported data. It’s difficult to assess behavioral and clinical outcomes.
