Health apps are everywhere … except the physician’s exam room.
Have you noticed that most people checking their watches aren’t looking for the time, but rather, for the number of steps they’ve taken today? The fact that so many people – an estimated 45% of Americans – wear fitness trackers has given rise to the term “quantified self.” There’s even a nonprofit based in the San Francisco Bay area called Quantified Self, whose tagline is “Self-knowledge through numbers.”
To date, consumers, employers and health plans have been responsible for driving much of the adoption of wearables and health apps, like fitness trackers. But it remains to be seen how – or if – physicians will jump in.
It’s not just about wellness anymore
Wearables range from Fitbits, AppleWatches and Galaxy Fits, to more sophisticated devices that collect information on blood pressure, glucose levels, oxygen levels and gastrointestinal issues. In fact, health apps are increasingly focused on health condition management rather than wellness management, with the former accounting for 47% of all apps in 2020, up from 28% in 2015, according to the research firm IQVIA Institute for Human Data Science. Mental health, diabetes and cardiovascular disease-related apps accounted for almost half of disease-specific apps in 2020.
Wearable health devices offer several benefits to users and healthcare providers, according to researchers from Cornell University in 2020:
- They offer a convenient way to monitor, store and share health information in real-time.
- They provide feedback to users to make appropriate changes to their daily routines or behavior.
- They can facilitate remote patient monitoring and provide proactive and faster data access to physicians.
- They can be particularly useful for patients with chronic conditions, patients with cardiovascular risks, and elderly populations.
Working with a mobile health app platform in Asia, the researchers monitored health activities (e.g., exercise, sleep, food intake) and blood glucose values of 1,070 diabetes patients over several months. They found the adoption of the mobile health app led to improvements in health behavior, reductions in blood glucose and glycated hemoglobin levels, and fewer hospital visits and lower medical expenses. Patients who used the app undertook more exercise, consumed healthier food, walked more steps and slept for longer periods of time, and they were more likely to substitute offline visits with telehealth visits.
The business model
Developers of digital health apps initially marketed and sold them using a direct-to-consumer business model, but developers of apps providing the most significant health benefits are increasingly targeting payers and employers, according to IQVIA.
The average employer offers more than 12 digital health programs to their workforce, prioritizing activity, fitness, and sleep programs; nutrition and weight management tools; and diabetes management and prevention programs, according to San Francisco-based Castlight Health. (Castlight identifies itself as a connected healthcare navigator, offering employers and health plans a menu of health resources and plan designs, including health apps.) Successful employers are likely to incentivize employee engagement to use these programs, resulting in engagement levels that are on average eight times higher than those without incentives, according to the company.
Vivante Health
One healthcare application company working directly with employers and health plans is Vivante Health, Chicago. Its digital health products are designed to provide personalized and comprehensive care for people with digestive conditions.
More than 70 million Americans suffer from digestive health issues such as irritable bowel syndrome, Crohn’s disease, gastroesophageal reflux disease or other chronic GI ailments, says Vivante Health CEO Bill Snyder. Furthermore, abdominal pain is the No. 1 reason for doctors’ appointments and emergency room visits, he says.
Introduced in 2019, the company’s digestive health program, GIThrive® is designed to combine interactive technology and 24/7 personal support from nurses, a registered dietitian and a health coach, who in turn are supported by a team of pharmacists, research psychologists, microbiome scientists and gastroenterology professionals.
“As part of our GIThrive program, we offer a dynamic technology platform that uses data-driven insights to personalize the experience for our members,” says Snyder. “It also includes novel biomarker collection, including an at-home microbiome test, GutCheck, and GIMate, which is a first-of-its-kind handheld breath hydrogen monitor.”
Snyder says that Vivante Health has proven:
- GIThrive consistently saves a company more than $840 annually per member on average – a 15% reduction in spend.
- 87% of members better manage their digestive symptoms since using GIThrive.
- 89% of members say their overall well-being improved since using GIThrive.
- 89 Net Promoter Score for GIThrive Care Team.
Health apps and medical practice
Despite the good statistics, it is questionable whether health apps have yet to become an integral part of medical practice.
“Overall, the penetration of digital health tools in gastroenterology patients is low,” says Simon Mathews, M.D., clinical advisory board member for Vivante Health and a gastroenterologist at the Johns Hopkins School of Medicine. “The most common way patients interact with the digital world is by searching online and reading more about their condition. Occasionally, they will bring in data reports related to a fitness tracking app.
“At GIThrive, we are looking to be additive to the care ecosystem and ensure we are getting patients to the right care at the right time. We provide immediate access to individuals who may have accessibility barriers based upon various socioeconomic factors. We immediately assess the acuity of our patients and engage them in an evidence-based clinical pathway to reduce their symptoms and get them feeling healthier quickly. We can refer higher-acuity patients to brick-and-mortar providers. We can capture additional longitudinal data that gives us unique insights into the needs of the patients we serve.
“We can share this information with providers to give them a more holistic picture of their patients so they are able to best meet their patients’ needs,” he says. “Vivante has received great feedback from providers associated with partner health plans on the program that we have built with patients’ provider relationships in mind.”
That said, integrating information from health apps won’t happen without effort. “Integration of digital programs is in large part very fragmented (as with the rest of healthcare!),” says Dr. Mathews. “Health systems or individual departments may have bespoke integrations, but there is no easy, universal approach that facilitates broad access. This barrier is changing, however, as interoperability standards become more commonplace, leading to greater flexibility.”
The Cornell University researchers raised the following concerns about integrating patient-generated health data into medical diagnostics and care:
- The ability of wearable devices to track, store, and transmit patients’ health information raises questions about data security and privacy.
- The design, accuracy, and reliability of wearables have been a major concern.
- Questions have been raised about the accuracy of data gathered by wearables in people of color.
- Technology acceptance of new wearable devices remains another significant barrier.
Wearables and health apps have also raised questions of health equity, according to the researchers. For example, in their study of patients with chronic diabetes, they noted that rewards [by payers or employers] based on healthier eating habits and lifestyles could end up rewarding the rich and penalizing the poor.
“The practice of physicians prescribing digital health programs is not mainstream,” says Dr. Mathews. “Changing physician behavior can be notoriously difficult, so going through health and employer plans is often more successful.
“The potential for impact is huge. As … barriers continue to drop, patients and providers will see the full potential impact of these solutions.”
