Benefits of Wearable Technology for Patients and Healthcare Professionals

The combination of digitization, artificial intelligence (AI), and machine learning in wearables offers the industry the following:

  • Real-time access to patient health data. Wearable medical devices make it easier for patients to get proper care because they enable real-time data tracking from a distance. According to a HIMSS survey, more than half of doctors think wearable technology in healthcare helps keep track of their patients.
  • Better accountability. Eventually, practitioners can collect data from wearable devices and sensors as part of their daily care. Digital technologies and merged data enable more accurate EMR, clinical expertise, and medical research, creating a more holistic medical picture at the micro and macro levels.
  • Improved medication compliance. Wearables can benefit patients in various ways, such as by sending them regular notifications about their medications and ensuring they are taken as prescribed. 
  • Reduced burden on staff. With a real-time remote measurement of patients’ physiological data, hospitals can free up beds; doctors can monitor patients’ vital signs no matter where they are and improve work efficiency. That is especially important as hospitals expand their telehealth and “at-home” care capabilities.
  • Greater patient outcomes. Connecting EHR and wearable devices benefits primary care patients and patients with chronic diseases. It helps practitioners reduce medical errors and identify potential problems early before they develop into serious health problems. According to Deloitte, over the next 25 years, patient monitoring technologies might help the healthcare sector save $200 billion.

The Challenges Faced by Wearable Technology in Healthcare

Wearable technologies provide many benefits to the healthcare industry. Still, to implement such devices in medical practice, they must meet stringent requirements for accuracy, availability, processing speed, low end-to-end latency, etc. In addition, there are other aspects that all developers and manufacturers of medical devices should consider.

  • Sensors inaccuracy. For example, some wearable devices allow you to track your VO2 max, measuring how much oxygen your body can use during exercise. According to a 2022 study, the VO2 maximum measured with wearable devices was less accurate than the laboratory VO2 max test performed by qualified medical practitioners.
  • Interoperability issues. There are many interoperability issues as wearables require different ways of collecting data, providing data according to other data models, etc. Developers must consider all these differences and develop appropriate interoperability solutions.
  • Surveillance and privacy abuse. According to a British Medical Journal study, 88% of mobile health apps can collect and potentially share user data. The FDA recommended manufacturers of medical devices (i.e., app developers) incorporate risk management programs to address vulnerabilities that may permit unauthorized access, modification, or patient information.
  • Small-screen form factor. The device has to be small enough for a person to comfortably wear it on their body, often under their clothes, while continuing to meet performance requirements for connectivity. It needs advances in software architecture to compensate for navigating challenges on such small-screen interfaces.
  • Ultra-low power operation. A wearable device should ideally sustain a lifetime operation without or with minimal user interference. That requires low-power operation for analog and digital electronics of a wearable.

Other pitfalls in wearable technology

As with many new technologies, wearables come with additional risks and unforeseen problems that need to be addressed. We have noted only a few key areas that may be of concern.

  • Device failure. Wearable device issues could lead to erroneous or incomplete patient data. Healthcare providers must ensure that devices are properly maintained and that data is backed up in case of failure.
  • Fakes. If consumers have a bad experience with knock-off wearables, they are much less likely to buy premium ones. Counterfeit wearables offer less than a tenth of the features or control, which could devalue the industry.
  • Device dependency. Using digital and wearable technologies in healthcare may lead to addiction. Healthcare providers should advise patients on properly using these gadgets and ensure they do not overuse them.
  • Health hazards. There are concerns that the constant use of digital devices can cause eye strain, neck pain, or carpal tunnel syndrome. Therefore, healthcare providers should educate patients about the potential dangers of using wearable devices and take steps to minimize those risks.
  • Battery life. If patients use a wearable ECG monitor, constantly changing or recharging batteries can burden and negatively impact their ability to live their lives. To optimize convenience and practicality, wearable device developers must consider the battery life of a product.
  • Usability.  Since the device is worn on the body, wearable technology in healthcare can withstand various conditions a person faces daily. For example, patients may be required to use a wearable diabetes monitor at all times, so they will shower with it, requiring it to meet different standards than a fixed medical device, which would normally not be submerged.

If efforts are made to address these issues, wearable technology will fundamentally change how medical treatment is delivered.

How Will Wearable Technology Affect Healthcare in the Future?

The wearable medical technology market is growing, and its development will put more wearable technology in the hands of consumers and businesses.

In particular, wearable devices will become less and less visible. Instead of a fitness bracelet or clip-on tracker, the devices will look more like jewelry, a patch, or a strap. In addition, device connectivity will expand as more accurate wearable sensors are developed, allowing doctors, insurance companies, and employers to promote healthy lifestyles and improve profitability.

Smartwatch innovation is rapidly progressing with advances in sensors, semiconductors, and artificial intelligence. For example, premium smartwatches are now equipped with optical sensors that continuously measure changes in blood volume and composition using photoplethysmography technology. Algorithms created and continually improved with machine learning use data from the sensors to deliver insights into users’ activity levels, stress, heart rate abnormalities, and more.

Another goal of wearable technology manufacturers is increasing battery life. Wearing a watch that has to be constantly removed to charge is frustrating. Therefore, engineers are actively working on wearable devices that can harvest energy from movement, heat, or ambient light, when worn directly on the body.

The application of AI in healthcare will increasingly influence the effectiveness of wearable devices. That will improve measurement accuracy and reduce cybersecurity risks. In addition, with the combination of IoT technologies and predictive analytics tools, healthcare can become more context-based and automatic and will help better understand patient data.

Applications will become more intelligent and dependable, allowing physicians and patients to track a broader range of health conditions. It is becoming apparent that it will stimulate more software development companies to produce software solutions to serve healthcare needs.
