For patients who live in rural areas, driving to see a specialist in a large city or at a university hospital can be challenging, if not impossible.

And yet, it’s a necessity for better health: People with liver disease often require multiple visits to adjust medications or treat related complications.

“I’ve always been frustrated when I can’t help patients who live in distant areas and don’t have a car or money for transportation,” says University of Michigan gastroenterologist Grace L. Su, MD who is chief of gastroenterology at the VA Ann Arbor Healthcare System.

Even when a patient is able to see his or her local primary care physician, problems could arise. Those practitioners may have knowledge gaps, little to no communication with the patient’s specialist, or time constraints that lead to poor quality care.

That divide is especially personal for Su.

After one of her patients died after he couldn’t return for a follow-up visit, she turned frustration into action by researching how technology could be applied to reach more rural patients and their doctors.

In a study published in Hepatology, Su and her team affirmed that communication is key: Patients of primary care physicians who participated in video consultations with liver disease specialists had a 54% higher survival rate than patients whose primary doctors didn’t participate in those exchanges.

“Primary care providers really want to do the right thing, but they may not have all the necessary tools,” says Su. “This research shows an excellent way to impart specialty knowledge to them. The learning is mutual. They are not just learning; they are teaching us.”

Joining forces via video

Such thinking isn’t new. Years ago, researchers at the University of New Mexico developed the Extension of Community Healthcare Outcome (ECHO) program to train primary care providers to treat hepatitis C in patients living in rural and remote areas.

The Veterans Health Administration adopted this “telementoring” model and renamed the program Specialty Care Access Network-Extension of Community Healthcare Outcome (SCAN-ECHO). The VA Ann Arbor Healthcare System was one of the first organizations to utilize the SCAN-ECHO program for chronic liver disease.

Using vital records provided by the Veterans Health Administration, researchers learned that there were 62,237 veteran patients with liver disease in Michigan, central Indiana, and northwest Ohio between 2011 to 2015.

Of that group, only 513 patients had a primary care physician who engaged in a SCAN-ECHO consultation about their case.

During those consultations, videoconferencing was used to link primary care providers and specialists. The individual patient cases were discussed and treatment plans and recommendations were made in real time. Patients whose cases were chosen to receive video consultation were more likely to be younger, live in rural areas, and have more severe liver disease, including evidence of cirrhosis.

Participating doctors benefit along with the patients.

“It is one thing for a primary care provider to read or learn about a disease, but another when they have a specific patient in mind. This case-based teaching magnifies the potential for learning. Creating many mini-specialists from primary care providers is the most powerful aspect of the SCAN-ECHO program,” says Su, who directs the SCAN-ECHO clinics at the Ann Arbor VA. “It’s a medical force multiplier.”
