A primary care medical group has a list of patients who had once used the group on a regular basis as their primary source of care. However, in scanning their records, these patients had not been in for an appointment in the past 2 years. The senior partner wants to send them an informational flyer about the practice and a refrigerator magnet that has the group's telephone number and after-hours service number. As the marketing director for the practice, evaluate this approach in light of the HIPAA regulations. Can it be implemented?
