Information technology has dramatically changed the way we live our lives in areas ranging from commerce and entertainment to voting. Now, policy advocates and government officials hope to bring the benefits of information technology to health care. Governments, hospitals, doctors, and pharmaceutical manufacturers have placed a tremendous amount of medical information, data,
and services online in recent years. Many consumers can visit health department
