Which of the following is an example of how the Internet has affected consumer health informatics?

• A. Provided the opportunity to contact the health care provider via e-mail.
• B. Created the ability to generate a physician bill.
• C. Afforded the option to opt out of supplying personal health information to drug companies.
• D. Given the ability to merge all data from health care providers and health plans into their personal health record.

Answer: (A)

The Internet has transformed consumer health informatics by enabling direct, two-way communication between patients and providers. Providing the ability to contact the health care provider via e-mail shows how online channels let patients ask questions, request information, and receive updates without phone delays, improving access, responsiveness, and engagement. The other options describe functions not primarily driven by Internet-enabled consumer health informatics: generating a physician bill is a billing activity, opting out of sharing personal health information is a privacy choice, and merging data from multiple providers into a personal health record involves broader data integration and interoperability challenges rather than a straightforward Internet-based patient–provider interaction.
