The market for mobile health apps is forecast to grow 70% over the next five years, to $392 million. Beyond improvements in technology there are several factors fueling this blistering growth.
- Increased incidence of chronic diseases. According to the CDC “chronic diseases – such as heart disease, stroke, cancer, diabetes andarthritis – are among the most common, costly and preventable of all health problems in the US.” Among these, diabetes is particularly significant. According the CDC’s 2011 National Diabetes Fact Sheet approximately 26 million or 8.3% of Americans have diabetes. As reported in the January 2012 edition of Health Affairs, an issue devoted entirely to diabetes,an additional 79 million Americans are at high risk of developing the disease over the next 10 years. The cost to treat and manage these patients is enormous. Health Affairs notes that $1 out of every $3 in Medicare is spent on the disease. UnitedHealth,one of the nation’s largest health insurers, estimates that treating diabetes in the US will cost $3.4 trillion from 2010 through 2020.
- Proven benefits of self-monitoring, communicating & collaborating. A study at Kaiser Permanente studied nearly 35,000 patients with chronic health conditions, including diabetes over a two month period. The study found that those patients who used email to communicate with their doctors saw a statistically significant improvement in various health measures. Mobile health apps are powerful because they facilitate more frequent communication and allow patients to more actively participate in disease management.
- Shift in how patients access health information. A survey conducted by the Pew Internet project found that 9 percent of cell phone owners have apps that they use to manage their health. The survey also found African Americans and Latinos were more likely to use mobile health apps. This is significant since, as reported by the CDC, these populations are at increased risk of developing chronic illnesses such as diabetes.
A sampling of mobile health apps for diabetes
Given the market size and the importance of disease monitoring and management, health apps for diabetics are among the most important being developed. The popular DiabetesMine blog does a nice job profiling the dozens of options available to patients. Some apps that have garnered significant attention include the following:
In 2010 WellDoc received FDA clearance to market its DiabetesManager. The software based app includes a medication adherence program and real-time transmission of blood glucose data to physicians. In a 12-month randomized controlled trial, whose results were published in the September 2011 issue of Diabetes Care, patients using the WellDoc app in addition to their usual care recorded a statistically significant decline in their glycated hemoglobin levels during the study period. Patients must use this phone-based system in partnership with their healthcare providers.
The Glooko iPhone app introduced late last fall, enables patients to more easily record and report their blood glucose readings. By connecting their existing blood glucose monitor to an iPhone via a cable patients can use the app to send their readings to physicians by email or fax. The iBGStar blood glucose monitor from Sanofi-Aventis cuts the cable by plugging directly into a patient’s iPhone. The monitor also received FDA clearance in December 2011.
Another high tech solution to blood glucose monitoring was reported last week by Walter Mossberg , a technology columnist fo rthe Wall Street Journal, who is also a Type 2 diabetic. Mossberg reviewed the Telcare blood glucose meter which wirelessly transmits readings to a patient’s iPhone and a secure database that can be accessed by a patient’s physician. The Telcare meter has been also been cleared by the FDA.
Beyond smartphones
A lot of attention has been focused on using smartphones to manage diseases but not all patients have them. Text messaging has also been successfully used to send patients important health messages and reminders, as demonstrated by the Text4Baby campaign, a program for expectant mothers. More recently the BeaconCommunity health program announced the development of an initiative for diabetes management using text messaging at its sites located in Louisiana and Michigan, areas where the impact of diabetes has been particularly significant.
What’s next?
We can expect to see continued development of mobile devices to allow patient self-monitoring for chronic conditions. Increasingly, these devices will facilitate sharing of patient level data with health care providers and communication between patients and providers in response to these data.
