    For digital diabetes care, is more data always better?


    Digital behavioral well being applications are making a daring pitch to payers, employers, and sufferers themselves: Shell out upfront for our digital teaching and distant monitoring, and we’ll prevent cash by avoiding expensive issues from diabetes and different ailments in the long term.

    For diabetes, which practically tops the list of persistent well being circumstances by price, many digital applications are selling steady glucose monitoring as a part of that promise. “We simply began to see that with CGMs, it’s a foregone conclusion that they’re going to be the dominant answer,” mentioned Sean Duffy, co-founder and CEO of digital care firm Omada Well being. The units, which stream customers’ blood glucose knowledge all through the day, are mostly utilized by individuals who want a number of day by day doses of insulin to handle their diabetes, however “this isn’t only for individuals who inject insulin,” mentioned Duffy. “We determined that it was going to be desk stakes and Omada wanted to energy CGM and training in a very deep method.”

    Digital care corporations don’t have the info to again that technique up simply but, although. Not each diabetes affected person will profit from sporting a tool that tracks their blood glucose day in and day trip. The rising adoption of CGMs, although, will present a take a look at. Previously few years, many applications have inked partnerships with producers to get sensors onto the arms and bellies of extra kind 2 diabetes sufferers, together with those that don’t use insulin. In 2019, Omada established a partnership with Abbott that provided FreeStyle Libre prescriptions to some members recognized with kind 2 diabetes, together with a wi-fi scale. Livongo partnered with Dexcom in 2020 to include its CGM knowledge into its program; the identical 12 months, UnitedHealth Group launched Level2, offering customers with teaching together with a free Fitbit and Dexcom G6.


    The information rolling in may assist digital care corporations decide the worth of CGMs — each for sufferers and for his or her backside traces.

    A number of the applications goal to synthesize glucose knowledge into tendencies, algorithmically figuring out a behavior change which may preserve a consumer from dipping into harmful glucose territory in a single day, or preserve them from spiking their ranges too excessive. “Typically it may be like knowledge overload,” mentioned Tejaswi Kompala, an endocrinologist and scientific program director at Teladoc, which owns Livongo. “Customers aren’t incessantly wanting retrospectively, to take a look at patterns and tendencies.” So the corporate “nudges” customers when it notices vital adjustments of their blood glucose patterns. Others merely feed the info to coaches or diabetes educators for one-on-one assist connecting info on meals, remedy, and exercise with glucose metrics like time in vary.


    There may be some analysis suggesting that steady glucose monitoring can bolster an app-based method to illness administration. On the American Diabetes Affiliation’s annual scientific session in 2021, Onduo revealed a research of just about 800 customers in its digital diabetes program, each with and with out intermittent CGM use. CGM customers noticed a much bigger lower in blood glucose over six months than non-CGM customers. Amongst customers with excessive A1Cs, a measure of long-term blood sugar management, the drop was 2.8%, in comparison with 1.8% amongst non-CGM customers.

    However the teams weren’t managed for variations in age, beginning A1C, or insulin use — which means the higher drop in A1C may very well be attributed to having extra severe illness, and subsequently extra room to enhance. And whereas analysis typically reveals that well being care prices rise and fall together with A1C ranges, the connection between particular CGM-based applications’ impression on A1C and price financial savings relative to different interventions is much less clear. Studies funded by machine makers level to an financial profit for CGM use in sufferers with kind 1 diabetes — with A1C drops probably driving financial savings of $3,000 to $7,000 over three years in one analysis — however research on the cost-effectiveness for kind 2 diabetes is extra restricted.

    Which means not each digital diabetes care firm is all in on CGMs. “We consider CGM is for everybody,” mentioned Henrik Berggren of digital diabetes clinic Regular Well being, which was acquired by major care supplier Carbon Well being in June 2021. “However the actuality in the present day is that these units are nonetheless fairly costly,” costing from $150 to $400 a month out of pocket. Insurance coverage recurrently covers the units just for individuals with diabetes on intensive insulin regimens. Till Regular was acquired by Carbon, it targeted its applications on sufferers for whom CGM was reimbursed.

    Virta, a digital program that gives dietary help for a ketogenic weight-reduction plan, can also be conservative in its method to the units. “We’re very a lot targeted on outcomes, and for what we do, which is provider-led vitamin to reverse kind 2 diabetes, CGM is just not mandatory,” mentioned Virta CEO and co-founder Sami Inkinen. Whereas the Virta program can ingest CGM knowledge if customers have already got a tool, its default is to make use of fingerstick glucose readings.

    “We get the identical finish outcome with both know-how,” mentioned Inkinen. “It’s a bit of bit sooner and there’s much less trial and error when you’re on a CGM; it’s useful to have that suggestions loop. Nevertheless it’s powerful to quantify what that will be value in greenback phrases. I’d by no means make the assertion that given the identical value, that pricking a finger thrice a day is healthier than simply having correct CGM knowledge. However definitely the sort 1 market value is just not justifiable for your complete kind 2 inhabitants.”

    What quantity of individuals with kind 2 diabetes may profit from CGMs, then? And in what doses? “The frequency at which you utilize CGM in a person ought to be, actually, individualized,” mentioned Anne Peters, who directs the USC scientific diabetes applications and has suggested each Omada and Livongo.

    In her follow, Peters makes use of CGMs in individuals with each kind 1 and sort 2 diabetes, together with those that should not on intensive insulin regimens, to each titrate medicines and assist sufferers perceive how their behaviors impression their glucose ranges. “However I don’t suppose we have to have people who find themselves secure and doing nice do it repeatedly,” she mentioned. “There’s alternative ways to make use of CGM, and I believe we have to take a look at that.”

    Analysis designed to parse outcomes for various patterns of CGM use is minimal. “There’s actually a niche within the proof in what’s the proper cadence and quantity of wear and tear of CGM for individuals with kind 2 diabetes,” mentioned Jennifer Layne, senior director of medical affairs and scientific analysis at Onduo.

    To grasp whether or not CGMs make a significant distinction for individuals with kind 2 diabetes — the customers most focused by these sorts of illness administration apps — some corporations are investing in inner analysis that will assist decide what patterns of wear and tear are most useful and cost-efficient. “Onduo is absolutely uniquely located to ask these questions and try this analysis and get that knowledge,” mentioned Layne.

    “One of many issues we need to take into consideration are completely different patterns of CGM utilization and completely different sorts of schedules, and actually beginning to research populations the place we are able to take a look at brief time period and long run glycemic outcomes,” mentioned Erich Huang, who joined Onduo as its chief science and innovation officer in June 2021.

    Livongo can also be learning completely different patterns of intermittent CGM use in kind 2 customers. After the corporate was acquired by Teladoc in a 2020 deal value $18.5 billion, it began a pilot program with Dexcom to broaden CGM entry for free of charge to some individuals with kind 2 diabetes who weren’t intensive insulin customers. Now, it’s monitoring affected person engagement, scientific outcomes, and monetary outcomes amongst a few of these customers with various CGM use.

    “The objectives are in fact wanting to grasp scientific outcomes, can we drive enhancements in individuals’s glycemic management via this intermittent CGM use,” mentioned Kompala. “After which, what can we perceive concerning the dose of CGM, the frequency of CGM … What can we study what makes the CGM put on expertise essentially the most significant?”

    As these corporations work to find out one of the best ways to deploy CGMs, the analysis behind the worth of their platforms general remains to be in query. Some research recommend digital behavioral interventions can enhance affected person outcomes, however their worth relative to different care fashions remains to be unproven, as Yale Faculty of Medication endocrinologist Kasia Lipska argued in a debate eventually 12 months’s American Diabetes Affiliation assembly.

    However she acknowledged that app-based platforms have responded to a significant failure in diabetes care. As endocrinologists and first care suppliers work to stem the tide of diabetes, many have bother making an impression with the usual 4, 15-minute appointments they may have with a affected person annually.

    “Our care has been so shrunken by way of the time you spend with sufferers,” mentioned Lipska, “that these corporations are actually filling that void.”
