Wearable Medical Devices | Health Technologies Transforming Remote Care

Wearable medical devices are rapidly transforming the healthcare landscape, empowering patients and providers with real-time health insights. At Knowledge Galaxy, we’re diving into everything you need to know about these cutting-edge devices, their examples, top companies, and future potential. Anna Taylor was among the first to purchase the Apple Watch when it debuted in April 2015. Already equipped with a Fitbit step-tracker as part of an employee-sponsored health program, Taylor, a data informaticist, was eager to explore Apple’s offering.

“I hated it,” recalls Taylor, now the associate vice president of population health and value-based care for Washington state-based MultiCare. “It didn’t provide the data I needed, and I disliked the graphical user interface.” However, the landscape of wearable technology has significantly evolved since then.

MultiCare now uses the Apple Watch to gather data from patients in its cardiac rehabilitation program. The device, which can provide heart rate and rhythm notifications and has received regulatory clearance as an electrocardiogram monitor, is just one example of how wearables have advanced. Today, wearables are not just wrist-bound but are also integrated into clothing, enhancing their potential to support remote care, including home healthcare initiatives.

However, the rapid evolution of these devices and the real-time availability of data can leave organizations struggling to manage information, software integrations, and security settings. With both clinical and IT staff experiencing burnout, this can be a daunting task.

An Overview of the Wearable Market in Healthcare

MarketsandMarkets predicts that the global market for wearable healthcare devices will approach $70 billion by 2028, with an annual growth rate exceeding 11 percent. Devices fall into two broad categories:

1. Medical-Grade Wearables: These include blood pressure, glucose, and heart monitors. These devices undergo clinical research and require FDA clearance to gather data for clinical decision-making. Common use cases include monitoring patients post-surgery or assisting with self-management of chronic conditions like diabetes and hypertension.
2. Consumer-Grade Wearables: This category includes watches, rings, and clothing. These devices account for the largest share of the wearable market due to increased availability, interest in real-time health monitoring, the rise of 5G, and the proliferation of smartphone apps for data management.

However, a 2022 literature review noted concerns about the accuracy and reliability of device sensors, as consumer-grade devices are not subject to the same scrutiny as medical-grade wearables. Battery life and usability issues, such as small text and hard-to-use clasps, can also pose challenges.

The Benefits of Wearables in Healthcare

The same literature review highlighted significant benefits of wearables in health and wellness management. Ongoing tracking helps patients set goals, while companion applications provide context, tailored support, and better understanding of their conditions. Providers also gain a more holistic view of patient health beyond what is reported during short appointments.

This is made possible through open application programming interfaces (APIs). Devices like the Apple Watch and apps like Apple Health have the infrastructure to get data where it needs to be, says Taylor. “It can be visualized for patients to encourage healthy habits or used within the electronic health record to make clinical decisions.”

MultiCare has seen success with wearables in two specific instances:

1. Care Management under Risk-Based Contracting: This works well because the economic model supports both the purchase of devices for patients and the staffing of care managers and remote monitors. “We see a difference in outcomes with wrap-around care management,” says Taylor. “Helping patients use the devices helps create good habits.”
2. Remote Patient Monitoring for Chronic Conditions: This has contributed to increased patient involvement in self-management and decreased readmissions associated with chronic conditions, says Chad Gabelein, MultiCare’s telehealth services director. Care management plays a pivotal role in this success.

The Challenges of Wearables in Healthcare

The need for finesse in managing wearables data highlights the challenges of wider adoption. “The availability of data has almost exceeded our ability to manage it and use it to its most effective capacity,” says Gabelein.

For example, monitoring a patient post-congestive heart failure would require a primary care provider to review data streams of vital signs generated 24/7, which is impractical given their workload. “Practitioners have to be able to react to trends, not just data,” adds Gabelein. “We need to drive automation in teasing out and trending values for patients.”

Even with analytics tools, organizations need the computing power to process them. This may motivate a health system to migrate to a cloud-based electronic health record, says Taylor. The sheer volume of wearables, especially in the consumer-grade market, also poses an obstacle, as no organization can account for every open API needed for integration.

Security priorities must also be shifted, with an emphasis on device identity management and verification at the point of care.

The Future of Wearable Technology in Healthcare

A 2022 paper provided four recommendations for supporting more effective use of wearables in healthcare:

1. Context-Based Data Quality Standards: False positives are acceptable for fitness tracking but should be limited for remote monitoring of vital signs and all but eliminated for diagnostics.
2. Interoperable Data: This addresses concerns about data ingestion and storage and makes standards easier to apply.
3. Access to Data and Analytics Tools: Eliminating barriers to accessing information and insight from wearables increases the likelihood of long-term adoption.
4. A More Representative User Base: The industry should strive to promote the benefits of wearables for wellness, not just health monitoring, especially among populations traditionally excluded from clinical research.

Additional research has pointed to the potential for wearables to address issues of inequity in maternity care and broaden participation in early-stage clinical trials.

Ultimately, Gabelein says, organizations are more likely to succeed with wearables when their strategy looks beyond the devices themselves. “You have to associate wearables and their data with artificial intelligence. The AI overlay helps you identify the most effective and necessary data, so you can be conscientious about the amount of meaningful data you send to clinicians.”
