Main Line Health, a system with facilities in the Philadelphia region, wanted to increase referrals to their cardiovascular medicine and surgery programs. Given the multitude of well-known hospitals—and cardiovascular programs—in the Philadelphia area alone, the organization looked to Doximity to partner on a creative, strategic approach to stand out from the competition.

The Partnership

Although this was only their first year working with Doximity and using Colleague Connect®, Main Line Health took a very sophisticated approach to increase referrals. The health system’s cardiovascular marketing team worked with the System Chief of Cardiovascular Disease as a Featured Physician and Brand Ambassador to reach out to external physicians on Doximity. His  message introduced the new System Chief of Cardiac Surgery at Main Line Health. Regarded as a top cardiothoracic surgeon, his colleague's name would garner attention in the medical community. This tactic certainly worked, with an open rate of 81% and a connection rate of 26%, compared to the average benchmarks of 47% and 14%, respectively.

After sending out the Colleague Connect® messages, Main Line Health and Doximity identified the most engaged audience members, and followed up with a DocNews® campaign. This type of content journey strategy proved to be successful and helped them reach their goals. From this campaign alone, 16 new providers began referring to Main Line Health with 65 net new patients, resulting in a return on investment of 57:1.
