Clearer Answers, Built-In Education: How Dr. Sarah Byrne, MD Brings Gut Health into Primary Care

Summary

Dr. Sarah Byrne is a board-certified family medicine physician and the owner and Medical Director of Root Family Medicine. Root uses a hybrid model, in which most providers work in a membership model but can still bill insurance for primary care. She has over 15 years of experience blending functional medicine, primary care, and  a love of herbal medicine, as she digs into underlying factors like gut health, stress, and diet. Living with celiac disease has made her especially passionate about gut health, and her favorite part of her work is caring for whole families as they grow.

Why she switched
Dr. Byrne has been doing some form of gut testing since 2011. With PCR testing, she'd get results showing which species were high or low, but she wasn't always sure what to do next. "In primary care, I'm not an expert in every bacteria," she says. After a few patients told her they'd found Tiny Health helpful, she took a closer look at shotgun sequencing. Seeing what the microbes are actually doing (i.e. their functional capacity), not just which ones are there, gives her a practical picture of what's happening in the gut and how to improve it.

How she uses Tiny Health

The patient and provider interface was a big draw for Dr. Byrne. Patients can click into their results to learn about each species, and the portal's educational resources are updated over time with the most current, emerging research. "I love that it is on the patient's side, so they aren't just getting a sheet of paper with bacteria that they can't understand," she says. 

Getting started

The built-in education was a big part of how she was able to make the switch from PCR to Tiny Health so successfully. She reviews new results with Tiny Health's microbiome specialists and reaches out when a new metric comes up to learn more.  “There's a lot of education in there. I learned a lot just ordering the tests and navigating it for myself."

What she'd tell other practitioners
"Once I started doing this test, I really stopped doing all the other tests because I just found it so much more useful and practical… I just don't see why I would use another test." Price matters too, since insurance often doesn't cover gut testing. She finds the standard gut test cheaper and more useful than what she used before, and the PRO kit comparable in price to competitor tests. Collection is also far easier, which makes patients more willing to retest.

In her words

  • "You can utilize the interface to teach your patients, and you can learn and continue to learn [from] the coaches at Tiny Health."
  • "It's an easier ask, a better price point… then you can even repeat it and see how [they] are.”

Q: Tell us a little about yourself and Root Family Medicine, it’s combination model with concierge and membership options, and what makes your approach different?

A: We have been open since 2015, and initially it was started because I can't picture anywhere I would be able to work; this didn't necessarily exist at the time. We incorporated some integrative aspects, and looking to all of the things related to a person, and I had been doing functional medicine at the time, but I also love primary care because I found that when you're the PCP, you're the person someone is going to, and you're taking care of them over time, and you can't parse out certain pieces of it. I want to know when they have a cold, because you might look at things differently rather than just doing… We've evolved over time and now offer more than your average PCP place, where we try to dig into things more than other places do, and that takes time, and think about underlying factors and whether it is gut health, stress, diet, or anything. I also love herbal medicine and being able to bring that into practice. I love herbs because herbs are so versatile, and so many are safe, and they can be inexpensive. We are currently a hybrid: most of the providers are in a membership model, and we still bill insurance, which is nice for primary care, and we can still communicate with specialists efficiently, and then patients pay an annual fee that allows us to do all of the other things we offer and spend more time. I am doing concierge myself, as I manage the clinic and other providers.

Q: What made you want to add gut testing to your practice, PCR vs now shotgun? / Before Tiny Health, you used pcr testing - why did you decide to try shotgun testing with Tiny Health?

A: I have probably been doing some version of gut testing since 2011, and all that was available was pre-PCR (culture, way back), and I've tried some of the other testing that is available out there through the years. And as you learn more, you change over time and want the test to be able to change what I am doing for that patient and give enough info to make it relevant and practical. So one struggle I had with the PCR test I had is you get the results back and you're like, "Well, this species is high and this one's low and this one's in the middle," and I could kind of pick out, "I know you need bifido," so if that was low I could do something, perhaps, but a bunch of other ones where I wasn't… you know, in primary care, you know, I'm not an expert in every bacteria, so sometimes I wasn't quite sure what to do. I would look for patterns. I wasn't left with a clear picture of what that meant practically in the person, so. I had a few patients who had told me they had been using Tiny Health outside of the practice, and then finally I learned that you were working there (Danielle), so then we chatted. I had a few patients who used it and were finding it helpful. And then we had a few conversations about the shotgun approach, and how I explain it to patients is that we don't know all the species in the microbiome, so we don't know all of them yet, but we don't really know what we are looking for. How I explain it to people is that if you know what genes are present, you don't have to know all the species, but you can understand what they are doing. In my mind, it makes it more practical, and seeing what's happening in there and what can I do to improve that picture. That was a big part of it. I like testing to mean something practical for a person vs. just "OK, this level is high" or "this level is low, and we're going to give you this thing to change the level." That was one big aspect. The other thing was the interface for the patients and the providers. It gives you all of this information, which can be a lot, but if people are interested, they can go in and click on this thing and learn about what this species is, and there's a lot of education in there. I learned a lot just ordering the tests and navigating it for myself, but I love that it is on the patient's side, so they aren't just getting a sheet of paper with bacteria that they can't understand. I like for people to understand to the best that they can so they can see what's happening, and have these resources available to them is really important for them. I like the educational piece, and you can go back to it and learn it, and then when they update it, it updates it in the portal. The presentation and interface and ability to educate patients through the tests and for the providers

Q: How was the onboarding process to Tiny Health? / Was it difficult to make the switch from PCR to shotgun?

She agrees with Danielle that the built-in education was a big part of how she was able to make the switch from PCR to Tiny Health so successfully. “Because also meeting with the specialists at Tiny Health, you know, if I get a new test back for my patients and then do a lot of review sessions with the specialist has been super helpful. Reviewing it with the microbiome specialist has been helpful. To reach out to Tiny Health when we need help. Or like when there is a new metric, we can touch base with the specialists at Tiny Health.”

Q: What do you want other practitioners who are considering gut health testing to know about Tiny Health?

Once I started doing this test, I really stopped doing all the other tests because I just find it so much more useful and practical and really easier in a way to provide the patient with useful information, so I just don't see why I would use another test. From my perspective, a) this is giving you a clearer picture of what's happening in the gut, and b) in addition, you can utilize the interface to teach your patients, and you can learn and continue to learn [from] the coaches at Tiny Health. I have found it so much more useful. Also, the price point is important because a lot of the testing insurance doesn't cover, and the gut test (not PRO) is cheaper and more useful, and with the PRO kits it's comparable. AND WAY easier for the collection. Nobody wants to do the other type of stool collection. When I did this one, it's so much easier, which is a selling point. Cost and time and effort for patients. It's an easier ask, a better price point, and easier, then you can even repeat it and see how you are. Whereas if something is so much more expensive and harder to collect, then patients aren't as willing to repeat the testing. That's important to me.
