What is the focus of consumer health informatics?

• A. Study, development, and implementation of telecommunications/apps/systems
• B. Diagnosis and treatment planning for patients
• C. Billing and insurance processing
• D. Clinical trial design and data analysis

Answer: (A)

Consumer health informatics centers on the design, study, and deployment of technologies that patients and the public use to access, manage, and share health information. This includes telecommunications, mobile apps, patient portals, and other consumer-facing systems, with emphasis on usability, accessibility, privacy, security, and interoperability to empower people in their health decisions and care management. That's why the focus is on the study, development, and implementation of these tools. Diagnosing and planning treatment is clinical care, billing and insurance processing is administrative, and clinical trial design/data analysis is research-focused—areas that belong to different domains.
