Going Independent Doesn't Mean Going It Alone. Dr. Basil Kahwash on Fixing Referrals and Building Physician Networks

Episode 78 • 7th May 2026 • How I Doctor with Dr. Graham Walker • Offcall

Most physicians have had a referral disappear. Many have spent days tracking down a colleague just to coordinate care for a single patient.

In this episode of How I Doctor, Offcall co-founder Dr. Graham Walker sits down with Dr. Basil Kahwash, an allergist and immunologist in Columbus, Ohio, to talk about one of the most universal and underappreciated problems in medicine: the referral system is broken, and independent physicians are paying the highest price.

Basil didn't set out to become an advocate for fixing referrals. He trained at Vanderbilt, where reaching a collaborating physician was as simple as sending an Epic message or jumping on a 20-minute Zoom call with three specialists at once. Then he went into independent practice in Columbus and discovered that none of that infrastructure existed. No shared records. No easy way to reach a referring physician. No directory of local specialists. Just a fax machine, a stack of paper charts, and a phone number he hoped was still current.

The referral black hole isn't just a physician frustration. It's a patient safety problem. Basil shares the story of a pregnant patient with a rare drug allergy whose referring OB-GYN he couldn't reach for three to four days. These aren't edge cases. They're a typical Tuesday.

Graham and Basil co-authored the referral manifesto at offcall.com/manifesto, making the case that independent practice doesn't have to mean isolated practice. This episode is the conversation behind that letter: what's actually broken, what it costs physicians and patients, and what a connected network of independent physicians could change.

What You'll Learn

How patients have become the de facto middlemen in a system that has no better option
Why most referrals arrive as little more than a diagnosis code, and what even a small amount of added context would change
How the fax machine became the rate-limiting step for physician collaboration and why EHRs haven't solved the problem
Why hyperlocal physician networks exist within specialties online but not across specialties within cities, and what filling that gap could look like
What winning looks like if the referral problem gets solved: coordination fades into the background and physicians get back to patient care
