Wearing a fitness tracking device could earn you cash from your health insurance company. At first, this sounds lucrative for the people who participate, and good for the companies, who want healthier insurance customers. But it’s not quite so simple.
Under the program, people who have certain health insurance coverage plans with United Healthcare can elect to wear a Fitbit activity tracker and share their data with the insurance company. The data would be analyzed by Qualcomm Life, a company that processes medical data from wireless sensors for doctors, hospitals and insurance companies. Depending on how active participants are, as measured by the Fitbit, they could earn as much as US$1,500 toward health care services each year.
Interest in wearable fitness trackers is booming. More than half of people who already own one believe their devices will help them increase their life expectancy by 10 years – even though it’s impossible to actually know that because the clinical trials necessary would take at least a decade. Adding free money to the mix only makes the devices seem more attractive.
Before we celebrate this new partnership, though, it’s important to consider potential costs to the patients. We are not far from days when wearable health devices will be able to diagnose illnesses. Corporate partnerships like this one with United Healthcare and Fitbit could pave the way for insurance companies to use fitness tracker data to deny coverage or hike up rates for consumers.
Diagnosis by device
There are positive elements to pairing wearable fitness trackers with health data.
An existing flu treatment medication works best when administered within 24 hours of onset of symptoms. But it’s difficult to catch the flu so quickly. A Fitbit could make that much easier. If the device measures a sudden decrease in the number of steps the person takes per day, plus perhaps an elevated resting heart rate, or new tremors signaling chills, that could signal the presence of a virus.
If an insurance company has access to those data, it could send a message to the patient. If the person really was feeling poorly (rather than just having decided to watch TV all day or gotten snowed in), she could be directed to go to her doctor or an urgent care clinic. The person could see a health professional quickly, get an effective treatment and be on the mend sooner – thanks to her Fitbit data.

This ability will only increase in the future. There are more than 20 clinical trials using Fitbits underway, studying the role of activity in treating pediatric obesity and cystic fibrosis, and even how it can boost chemotherapy’s effectiveness and speed in recovery from surgery. As those studies are published in the coming years, researchers and doctors will get even better at identifying signals of specific diseases in wearable devices’ data.
Beyond the Fitbit
Similar efforts include one to detect influenza with a portable heart-rate monitor. Other researchers are analyzing voice and speech patterns to reveal neurological disorders and other diseases – and are using calls to a health insurance company as a data source. Even eye-tracking software could measure cognitive understanding, which could identify signs of dementia. Detecting symptoms earlier through Fitbit data could allow faster, more effective treatment.
The biggest push, though, is coming from Qualcomm, which has offered a $10 million prize to the team who can develop a specific type of multifunction medical device. Without involving a health care worker or facility, the device must be able to accurately diagnose 13 health conditions, including pneumonia and diabetes. It must also be able to capture in real time five vital signs, such as heart rate and breathing rate, and process the data locally.
The global competition is down to finalists; the winner will be announced early this year. That could bring wearables’ insights to doctors – and insurance companies – much sooner than we might think.
Cause for concern
Wearables’ data can definitely be used to help patients. But it could also be used to harm them, particularly in light of recent political developments. With the passage of the Affordable Care Act (also called Obamacare), insurance companies were barred from denying coverage to customers who had preexisting medical conditions at the time they signed up for insurance. If that rule is lifted by Republicans in Congress, insurers might look to wearable devices for evidence they could use to refuse to pay for patients’ health care.
This development would have enormous consequences. According to the Centers for Medicare and Medicaid Services, as many as half of all Americans have some sort of condition that could be used to exclude them from coverage, such as asthma, cancer or mental illness. Might insurance companies ask prospective customers for their Fitbit data, in addition to – or even in lieu of – a physical exam or laboratory tests? Could they set rates based on what those data show – or deny coverage entirely?
Car insurance companies are already using similar methods. Some insurers provide their customers with devices to install in their cars, measuring drivers’ behavior and calculating the risk involved – and the rate they pay for coverage.
Assembling the data
At the moment, the algorithms are still under development. But the biggest thing United HealthCare needs now is a large data set of customer Fitbit measurements, so it can link them to insurance claims. Its new cash-for-data program will begin to assemble that information.
As insurance customers signed up to use a Fitbit and get some extra cash for sharing their data, United would be able to match their Fitbit measurements with any health conditions identified in their medical records. Over time, the company could build up enough information from, say, people with asthma and people without it to be able to tell asthma patients apart by looking just at their data. The company could do this for other common diseases, too, or even adapt the algorithms from the contestants in the Qualcomm competition.
It’s unclear what the company would do with what it learned. But one possibility is that when evaluating a prospective customer, the company could look at his data and know all about any preexisting conditions. That might mean a person doesn’t get insurance, or has to pay more for coverage.
Making coverage decisions
The financial power of the health insurance industry is enormous. Not only are there many large companies, but they have the ability to determine whether a sick person gets well or doesn’t – and whether the cost is ruinous or merely expensive.
Would people feel able to object if insurance companies required customers to wear fitness trackers or other monitoring devices? Would new patients provide access to past data a Fitbit collected? Could an insurance company consider it fraud if a user didn’t wear the device?
If used – and regulated – well, the devices can help individual patients change their daily habits to become healthier, saving insurance companies money, and passing some of those savings along to customers. Alternatively, the devices could provide justification for denying coverage to the inactive or unhealthy, or boosting their insurance rates.
Consumers should not assume their insurance companies will use their data only to improve patient care. With millions of dollars on the line, insurers will be sorely tempted. With the legal landscape around preexisting conditions in flux, people should think twice before signing up.
