Q: What role does diet play in improving the intestinal microbiome?
Dr. Ketover: When you look at people who are healthy and who have low incidence of chronic diseases or inflammatory conditions, obesity, cancer, we’re starting to study their microbiome to see how it differs from people who have those illnesses and conditions and try to understand what the different constituents are of the microbiome. And then the big question is: Okay, so once we know that, how do we take ‘the unhealthy microbiome’ and change it to the ‘healthy microbiome’?
The only method we currently have is fecal transplant for Clostridioides difficile. And that’s just not a feasible way to change the microbiome for most people.
Some studies are going on with this. There’s been laboratory studies done with lab animals that show that fecal transplant can reverse obesity.
Q: Describe your biggest practice-related challenge and what you are doing to address it.
Dr. Ketover: The biggest challenge these days for medical practices is the relationship with the payer world and prior authorization. Where we’ve seen the greatest impact of prior authorization, unfortunately, is in the Medicare Advantage programs. Payers receive money from the federal government on plans that they can better manage the patient on, rather than Medicare. That results in a tremendous amount of prior authorization.
I get particularly incensed when I see that a lot of payers are practicing medicine without a license and they’re not relying on the professionals who are actually in the exam room with patients and doing the history and physical examination to determine what is an appropriate course of diagnosis or therapy for a patient.
It comes around every January. We have patients who are stable on meds, then their insurance gets renewed and the pharmacy formulary changes. Patients stable on various therapies are either kicked off them, or we have to go through the prior authorization process again for the same patient for the umpteenth time to keep them on a stable therapy.
How do I address that? It’s in conversations with payers and policy makers. There’s a lot going on in Washington, talking about prior authorization. I’m not sure that non-practitioners fully feel the pain that it delivers to patients.
Q: What teacher or mentor had the greatest impact on you?
Dr. Ketover: Phillip M. Kibort, MD, the pediatric physician I worked with as a medical student who really turned me on to GI medicine. We worked together on several patients and I was able to develop an appreciation for the breadth and depth of GI-related abnormalities and diseases and therapies. And I really got excited by the spectrum of opportunity that I would have as a physician to help treat patients with GI illness.
Q: What would you do differently if you had a chance?
Dr. Ketover: I’d travel more both for work and for pleasure. I really enjoy my relationships that I’ve created with lots of other gastroenterologists as well as non-physicians around policy issues. I’m involved in a couple of national organizations that talk to politicians on Capitol Hill and at state houses about patient advocacy. I would have done more of that earlier in my career if I could have.
