Wearable Medical Devices Give Abundant Data—and Risks

Miranda Felde, MHA, CPHRM, Vice President, Patient Safety and Risk Management

Since 2013, the number of U.S. consumers tracking their health data with wearables has doubled.1 And that number continues to rise: During the third quarter of 2018, the wearables market saw a nearly 60 percent increase in earnings over the prior year.2

Wearables are electronic devices worn on the body, often like a watch. Wearables can track patient data like heart rate, blood pressure, or blood glucose. They can also track activity level, e.g., counting steps.

Promoters of wearables say that they could provide physicians with abundant data when caring for patients with chronic health issues. They also predict that combining wearables and gamification—e.g., competing with family members to see who can “score” the most steps in a day—may lead to improved health and better health outcomes.

However, skeptics question whether gamification will really lead to healthier behaviors long-term. And questions abound about what to do with wearables’ data and how to protect it. Wearables bring promise, but also real risks for patient safety and physician liability.

 

Benefits of Wearables

 

Promoters of wearables believe wearables will drive the transition to intelligent care, whereby physicians have access to more data—in which they can identify actionable components. Florence Comite, MD, a New York endocrinologist who describes wearables as “almost like magic,” uses data from wearables to tailor her interventions for patients with chronic conditions.3

Wearables can help patients take action, too. In one recent study, diabetes patients using a wearable app showed randomized controlled trial results comparable or superior to patients taking diabetes medications.4

Promoters of such digital strategies hope that they will encourage healthy behaviors while requiring fewer office visits purely for monitoring purposes, thereby reducing healthcare costs while improving patient experience and engagement. For instance, David Rhew, MD, chief medical officer for Samsung, hopes that wearables can help patients move to the highest level of patient activation, Level 4:5

The Four Levels of Patient Activation

 

  • Level 1: Predisposed to be passive. “My doctor is in charge of my health.”
  • Level 2: Building knowledge and confidence. “I could be doing more.”
  • Level 3: Taking action. “I’m part of my healthcare team.”
  • Level 4: Maintaining behaviors, pushing further. “I’m my own advocate.”

 

Some apps promote healthy behaviors with gamification.6 For instance, a user might compete with family or friends to take the most steps each day, either informally or through an organized group. Harvard professor Ichiro Kawachi, PhD, wrote in JAMA Internal Medicine that this is “an opportunity for clinicians to turn health promotion into an engaging, fulfilling and fun activity.”7 Sponsors hope that such groups can promote accountability, responsibility, and mindfulness about activity and health conditions.

 

Skepticism about Wearables

 

It is too soon to say whether wearables will increase healthy behaviors and/or reduce office visits, thus lowering healthcare costs. Some studies have found that wearable devices have no advantage over other forms of goal tracking or social support in helping people meet their health and fitness goals.8 A 2016 study from the University of Pittsburgh, for instance, found that “young adults who used fitness trackers in the study lost less weight than those in a control group who self-reported their exercise and diet.”9

 

Risks of Wearables

 

Though each device has its pros and cons, all wearables generate concerns for physicians, including:

 

  • Poor data quality: Data from wearables may or may not be reliable enough for medical use.10
  • Data fixation: Patients may fixate on one number—steps per day, for instance—at the expense of other health variables, such as their diet, sleep habits, etc.
  • Lack of interoperability with electronic health records (EHRs): If a patient’s wearable cannot stream data to the patient’s EHR, then how can the physician’s practice securely acquire the data?
  • Data saturation: Physicians receiving patient data from wearables risk being soaked by a data fire hose.11Physicians need a plan and a process to determine what measurements are relevant to a given patient.
  • Unclear physician responsibilities for collecting, monitoring, and protecting data: HIPAA applies to patient data collected by physicians,12 but differing state laws mean that a physician’s specific responsibilities for monitoring and protecting patient data vary by location.
  • Lack of data security—and liability for physicians: Wearables are subject to cyberattack. In addition to presenting obvious risks to patient safety, this may also present liability risks to physicians—who may be expected to notify patients of recalls issued for their wearables.13

Next Steps

 

As more and more physicians are accepting—or requesting—their patients’ data from wearables, questions include: How can we tell when data from wearables is accurate? When it’s actionable? When it’s secure?

Certainly, physicians interacting with data from wearables should independently confirm that data before changing a patient’s care, and should store data from wearables securely.
