Driven by fundamental business changes and seeking innovation to control rising costs, the U.S. healthcare market sees a big upside in deploying Internet of Things networks. The goal is to boost patient-centric care, provide more value-based services and offer more personalized medicine.

The potential for a healthcare IoMT—also referred to as the Internet of Medical Things (IoMT)—is huge. IoMT paves the way for a huge leap forward in patient care. What does IoMT in healthcare look like today and in the future?

IoMT smart sensors such as patient wearables and medical devices are connected to resources that detect issues in real time. The sensors transmit data over an IoMT network that is analyzed with machine learning and artificial intelligence (AI) software that initiate actions such as notifying caregivers or patients of impending issues. Consider these potential IoMT uses in a clinical or home-based care setting:

  • Cutting emergency room wait times. Who hasn’t endlessly sat in the ER waiting room? Comprehensive, IoMT-based ER resource tracking systems offer dramatic reductions on a real-time basis.
  • Remote health monitoring. Caregivers are being pushed to cut the length of hospital stays. Connected patient wearables provide constant monitoring to greatly improve in-home healing. Alerts can trigger caregiver queries or actions.
  • Ensuring critical equipment availability.  Like all machines, life-saving equipment can suffer power failures and breakdowns. An IoMT can sense if a piece of gear is near failure or in need of maintenance, proactively heading off the problem before it becomes critical.
  • Patient, staff, and supply management. All assets must be tracked. If the ER needs a defibrillator, an IoMT can tell if it’s been left in a nearby ER suite. Is a certain drug not available on a certain ward? Consult the IoMT-based drug tracking software. A patient comes into the ER but only speaks Italian. Is there an Italian speaker on duty? Guess where the answer can be found.
  • Improved drug management. Through small sensors in a pill transmitting to a patch worn by the patient, prescribers can determine if the medication has been taken and in what dose. Patients can also track their drug regimens through a smartphone app.

The impetus for such healthcare advances is nothing new, but IoMT now puts them within reach of health service providers, and even insurers. Technology has advanced, mostly through greatly improved computing power and connectivity, to provide a foundation for what might be called next gen healthcare.

None of this is some futuristic vision. IoMT infrastructure is already reshaping the healthcare industry, just as it has for manufacturing, energy, smart cities, retail, transportation and more. Most observers expect IoMT to quickly spread as wireless connectivity becomes even faster and more pervasive. IoMT networks, linking a wide variety of sensors, computing devices and analytic software applied to fast-streaming data, can be deployed today to connect patients with personalized medicine.  


Clinical Team Communication and Data Access in the Palm of Your Hand

Eisenhower Health, a west coast-based Magnet Hospital, implemented an enterprise-wide solution enabling mobile communications and collaboration across all care teams, linking the entire enterprise...

Once the technology has been implemented, the above changes can happen effortlessly, without human-to-human or human-to-computer interaction.

Optimized staffing and workflow

When an IoMT is implemented, significant value can be gained through operational improvements, which boost efficiencies that enhance quality of care and simultaneously reduce costs. Additional benefits can be gained through clinical improvements, which enable faster and more accurate diagnoses and a more patient-centric, scientific determination of the best therapeutic approach for better health outcomes.

IoMT in healthcare dramatically optimizes workflow and staffing. Even a basic IoMT solution can collect and bring together such data as staff location and expertise, patient acuity and location, and availability and location of critical diagnostic and therapeutic equipment.

With analytics, this data can help managers improve workflow and make better staffing and scheduling decisions. The data can also be used to understand the movement of people and assets, and to predict where staffing and equipment will be most needed the next day, or in the weeks ahead. Ideally, healthcare facilities will be able to move to appropriate dynamic, on-demand scheduling and resource allocation schemes. This ensures that the right people are assigned to the right places to efficiently deliver quality care while improving staff morale and patient satisfaction.

Fewer false alarms

The critical problem of alert fatigue in clinical care delivery is another pain point that can be addressed with IoMT. This occurs when care providers receive too many clinical alerts and become desensitized over time. With up to 99 percent of alerts being false alarms, alert fatigue is a life-threatening epidemic in healthcare settings, directly responsible for growing numbers of patient injuries and deaths.

With IoMT in healthcare, there are many ways to improve patient care and safety. For example, hospitals can use smart, connected monitoring devices that are linked to patient records, pharmacy systems, room location, nursing staff schedules and more. The sensors in these smart devices collect data, which is integrated with other medical device and system data and then analyzed to determine whether to trigger a silent alarm for a noncritical event or an audible alarm for a life-critical event.  In this way, IoMT will increase confidence in alarms, reduce work load and drive timely action—keeping patients safer.

Better diagnoses, better outcomes

The greatest opportunities for IoMT in healthcare may lie in helping clinicians make faster, more accurate diagnoses and more precise, personalized treatment plans. These capabilities can improve outcomes, reduce costs and ultimately provide greater access to high-quality care for more people across the globe.

Healthcare IoMT technology can integrate and analyze diverse types of diagnostically relevant data and move it to clinical decision support systems. Providers using these systems will have a more complete picture of each patient’s health, as well as the tools to make faster and more precise treatment recommendations. Such opportunities are already being realized in the diagnosis and treatment of sepsis, where speed and accuracy are critical to saving patients’ lives.

Such examples of how IoMT in healthcare shows that collecting granular patient data at frequencies previously unimaginable is within reach—not just when people are sick or in a hospital, but where people live and work. Think of the potential in clinical trials, as well. This data can be combined with behavioral, physiological, biochemical, genetic, genomic and epigenetic data and more.

Analytics will be able to detect new, previously hidden or unknown patterns and relationships between data, diagnoses, treatments and patient outcomes. The result will be next-generation expert systems that will eventually develop a level of autonomy in diagnosis and treatment. We’ll soon see them routinely assisting physicians and nurse practitioners, helping them provide high-quality care and achieve better patient outcomes at a lower cost.

The high volume and broad scope of healthcare IoMT data makes it possible to develop powerful learning and adaptive diagnostic and therapeutic models. The greatest opportunities for healthcare IoMT potentially lie in helping clinicians make faster, more accurate diagnoses and more precise, personalized treatment plans. This can improve outcomes, reduce costs and ultimately provide greater access to high-quality care globally.

The Vanderbilt Transplant Center is now giving patients and providers instant access to critical transplantation data—such as educational resources and donor information—on their smartphones and mobile devices.

According to the organization’s officials in a recent announcement, the app is designed to be a resource for transplant information at the Nashville-based Vanderbilt University Medical Center (VUMC) for both patients and providers.

“It helps patients find information about transplant programs as well as educational links about transplantation. Patients can customize what organ they are interested in learning more about, meet the transplant team and find provider locations. Living donor information is also available as well as a living donor referral form,” officials stated.

The Vanderbilt Transplant Center, Tennessee’s only full-service transplant center, provides chances for patients to participate in clinical trials and studies, as well as access to other specialists. Its transplant teams have performed more than 9,500 solid organ transplants since 1962, including all the major organs—heart, kidney, lung, liver and pancreas, according to its officials.

For providers, the app aims to offer improved access in the referring process for both adult and pediatric referrals through REDcap referral forms. The app gives referring physicians a secure process to contact the on-call VUMC transplant physicians to enable better communication, while also containing a direct link to call the VUMC Transfer Center for urgent transfers of patients to VUMC facilities. Providers also have access to outcome data, officials noted.

The Vanderbilt Transplant Center has debuted a new free app available for iOS and Android devices, available by searching “VUMC transplant” in the respective app store.

“Development of this app will allow patients unprecedented ability to connect with our system, schedule appointments and interact with our providers,” Seth Karp, M.D., H. William Scott Jr. professor and chair of the Department of Surgery and director of the Vanderbilt Transplant Center, said in a statement. “We have every expectation this service will increase our ability to reach patients and provide outstanding care.”

Edward Zavala, transplant center administrator, added, “The Vanderbilt Transplant app is a significant addition for our referring providers to access the transplant center. Additionally, the patient education component of the app provides patients ready access to transplant-specific education.”

Report: At-Risk Medicare Seniors the Next Apple Watch Target?

January 18, 2019

Apple is engaging in discussions with multiple private Medicare insurers about subsidizing the cost of the Apple Watch for at-risk people over 65 years old, according to a CNBC report.

This week’s report, from health tech reporter Christina Farr, noted, “The insurers are exploring ways to subsidize the cost of the device for those who can't afford the $279 price tag, which is the starting cost of an older model.”

The latest version of the Apple Watch—the Series 4—was launched in September, and as officials of the tech giant stated at the time, brings “advanced activity and communications features, along with revolutionary health capabilities, including a new accelerometer and gyroscope, which are able to detect hard falls, and an electrical heart rate sensor that can take an electrocardiogram (ECG) using the new ECG app.” This version retails for at least $399.

According to the CNBC report, “Apple has paid a visit to several of the largest insurers in the market, as well as some smaller, venture-backed Medicare Advantage plans. The people declined to be named as the discussions are still private.”

The watch’s electrocardiogram function and fall detection capabilities particularly make it appealing and valuable for seniors; about 19 million seniors, and growing, are enrolled in a Medicare Advantage plan, which are private health plans that receive government payouts for providing services to seniors—about $10,000 per member, on average, Farr’s report noted.

According to Apple, the new Series 4 Apple Watch intermittently analyzes heart rhythms in the background and sends a notification if an irregular heart rhythm such as AFib is detected.  It can also alert the user if the heart rate exceeds or falls below a specified threshold.

And, the Apple Watch’s fall detection function utilizes a next-generation accelerometer and gyroscope, which measures up to 32 g-forces, along with custom algorithms to identify when hard falls occur, the company has stated.

To this end, data from health technology company HealthMine shows that 21 percent of Medicare Advantage beneficiaries use a fitness/activity/steps tracker; and 70 percent currently use digital tools, with a blood pressure monitor being used by 50 percent of beneficiaries.

In this realm, Apple is working with other major insurers as well. It was recently announced that UnitedHealthcare Motion, an employer-sponsored wellness program, is telling its participants they can get a free Apple Watch if they meet the insurer’s daily walking goals over a six-month period. For this initiative, program participants can use the Apple Watch to see how they are tracking against the program’s three daily goals—frequency, intensity, and tenacity—helping integrate physical activity and engagement with their health plan.

Industry observers have already begun to offer some reaction to CNBC’s story. In Farr’s report, Bob Sheehy, the CEO of Bright Health, an insurance start-up with a Medicare Advantage plan, and the former CEO of United Healthcare, spoke to the idea of seniors potentially avoiding expensive care visits by leveraging the device. “Avoiding one emergency room visit would more than pay for the device," said Sheehy.
