In the year 2000, about 10% of the world’s population was aged 60 or over. By 2015 that had risen to 12%. The United Nations’ projections indicate that will increase to 16% by 2030, and jump to 22% by 2050. The percentages may not seem alarming but this will put it into perspective: by 2025, the world’s population is set to be 8 billion, of which approximately 15% or 1.2 billion will be elderly. Essentially, that is almost equivalent to the population of the second most populous country in the world—India! Another alarming statistic is the projected decline in the working-age population (25–59) between 2030 and 2050, meaning that there will be fewer people to support the growing elderly population, financially and otherwise!

But why does this matter so much? The answer is medical costs! Healthcare expenditure on the elderly is a growing concern, as it accounts for a higher share of expenditure compared to other age groups. For example the Centers for Medicare & Medicaid Services estimate that while the US elderly population in 2010 was about 13%, it accounted for 34% of the total healthcare expenditure. As life expectancy rises in the future, the share of expenditure too, is expected to rise. It is also estimated that elderly health expenditure may more than double between the ages of 70 and 90, depending on the region. With rising pressure on governments, payers, and manufacturers to reduce healthcare costs, senior care needs solutions in order to be prepared for this impending rise in expenditure.

Digital technologies and, specifically the Internet of Medical Things (IoMT), have tremendous potential to help. Frost & Sullivan’s detailed analysis on the growth opportunities in IoMT, has yielded10 ways that IoMT can help provide better eldercare and, in turn, control medical costs.

1. Vitals Tracking Wearables

A majority of seniors suffer from non-communicable diseases including cardiac ailments, diabetes, and hypertension. For cardiac patients, heart monitors that can monitor ailments such as arrhythmia and alert doctors about adverse events in real time can help prevent further complications. For example, InfoBionic’s MoMe Kardia device does exactly that. Other monitors such as Cortrium’s C3 Holter Monitor and Uber Diagnostic’s CardioTrack are also available. ‘Smart’ glucometers such as Dario that can communicate the measured blood glucose readings to an app on a smartphone for storage, tracking, and managing diabetes can help elderly patients better manage their diabetes. Regular activity monitoring and heart rate monitoring can be achieved by one of the several available consumer wearable devices and smartwatches. Even when hospitalized, IoMT platforms such as the one provided by Vitls can help nurses and off-campus physicians continuously monitor seniors’ vital signs without disturbing them.

2. Medication Adherence Tools

Seniors have several medications that they need to take and with age, remembering everything becomes a challenge. Missed doses can result in exacerbation of medical conditions and in some severe cases it can even lead to serious consequences requiring hospitalization. Several IoMT products address this challenge by helping users remember when to take their medication. Products from AdhereTech, Amiko.IO, MyUBox, MedMinder, and Vitality GlowCaps tackle this challenge in their own unique ways, helping the healthcare industry by saving on costs.

3. Virtual Home Assistants

Quite a few seniors live alone or with their spouses or partners, who are also most often likely to be elderly, and require daily assistance as well as companionship. Virtual assistants such as Catalia Health’s Mabu robot, or Intuition Robotics ElliQ robot serve this purpose well. Not only do they interact with seniors through voice and touchscreens, they can also help them stay connected with their family and friends digitally using social media platforms and video chat. Additionally, they can help patients remember to take their medications, take notes, and remind them about their care providers’ medical advice. Apart from their presence in seniors’ homes, these virtual assistants can also be reached through text and mobile phones through chat. Other than robots, another category of virtual assistants is voice interactive digital assistants such as Amazon Echo or the healthcare-specific version provided by Lenovo Health in partnership with Orbita Health. For seniors, such devices can be used for medication adherence, care coordination, and patient engagement, all areas in which (considerable) healthcare cost savings can be made.

4. Portable Diagnostics Devices

Seniors need to have their biomarkers tested more frequently than others to monitor existing conditions, diagnose new ones, and to check on the overall wellbeing. Instead of frequently visiting a pathology laboratory for getting urine or blood tests done, smart and portable diagnostics devices can help seniors perform such tests in the comfort of their homes and get results in formats that allow them to be instantly shared with their care providers. Consider the Scanadu Urine Kit for biomarker analysis or the Cue device that can test Vitamin D levels. In the future, additional tests may become available that will expand the potential of home testing for seniors. The added convenience means that seniors can perform diagnostic tests more frequently, helping to diagnose diseases and thus, to begin treatment sooner, ensuring that complications are prevented to save avoidable healthcare costs.

5. Personal Emergency Response Systems

The concept is well known among many eldercare market participants. Several products are already well established and serve many needs of seniors, inside and outside their residences, such as fall detection, emergency assistance, and navigation guidance back to the residence (for dementia patients, for example) or even boundary perimeter breach alerts (for Alzheimer’s patients, for example). Some products even include additional features such as medication reminders. Several companies ranging from healthcare majors such as Philips to smaller companies and startups such as Everon, Qmedic, Lively, Motech, MobileHelp, Jupl, and UnaliWear provide these products. In addition, a unique concept that goes beyond simple fall detection, is that of ActiveProtective’s smart belt that detects falls and deploys air bags to prevent fall-related injuries and uses the Bluetooth technology to trigger an alert to designated emergency contacts. Technologies such as these can help save avoidable fall-related healthcare costs.

6. Disability Assistance Tools

Varied smart products are available for some disabilities that seniors suffer from. One of the most interesting ones is Opn Smart Hearing Aids by Oticon. With features such as direct Bluetooth connectivity to smartphones for calls or for streaming music and the ability to control volume and switch programs on television with smartphone app support, it is a ‘smart’ solution for seniors. Another solution for sensory- and cognitive-impaired seniors is Nominet’s PIPS for the management of daily routines. The customizable colored buttons installed in seniors’ residences flash until the task that patients are being reminded of is performed and the button is pressed by the user. Pressing a button activates the next button in sequence. Functions can include daily tasks such as brushing teeth or even medical tasks such as taking medication.

7. Smart Implants

Pacemakers that communicate data to smartphone apps for sharing with physicians (Medtronic MyCareLink), sensors that are embedded in orthopedic implants to communicate performance post-surgery (OrthoSensor) or glucose-sensors that communicate diabetics’ glucose levels to smartphones or dedicated readers (such as products in development by GlySens, Senseonics, Echo Therapeutics, or Google’s smart lens) are all examples of smart implants. These can help seniors take care of their health and manage their conditions better, ensuring that medical intervention is sought immediately when required.

8. Smart Senior Homes

Care staff can monitor seniors with the use of wrist-worn wearables that track their location as well as activities performed (such as bathing, walking, sleeping, and so on). The Tempo wearable by CarePredict also allows seniors to request assistance with the touch of one button and will soon also provide two-way audio communication with care staff. However, the true power of the technology lies in machine learning and predictive analytics to derive insights from seniors’ daily routines as well as any deviations. Insights could include emerging physical or mental health conditions, which can help alert care providers to the need for immediate medical intervention. A similar example is the Mimo-Care solution that can issue three types of alerts to care staff for monitored seniors: red alert (potential fall or night wandering), orange alert (irregularities in daily routine, such as not eating regularly), and yellow alert (for domestic issues such as refrigerator door left open).

9. Family Caregiver Remote Monitoring Tools

Products from 3rings, Evermind, and Sonamba help family members monitor seniors remotely, without contacting them directly. For example, the 3rings smart plug notifies family members each time the connected device is turned on, a coffee machine for example¬, allowing a family member to know that it was turned on at the regular time indicating normalcy in routine. Any deviation in routine will be detected and family members can contact seniors to ensure that seniors are indeed alright. While Evermind provides a similar product, Sonamba’s product line goes beyond this by also providing medication reminders, an emergency panic button, and the ability to share digital photos with senior loved ones as well as a texting interface that is easy for seniors to use. A slightly different approach is Welbi’s platform that connects existing fitness trackers or smartwatches to monitor health and activity, and alerts caregivers when any deviation occurs. These technologies ensure that seniors are constantly but non-intrusively monitored and receive immediate attention and medical assistance when it may be needed the most.

10. Other Approaches

Several innovative devices are being developed to help medical challenges. Consider the Opnwatr.IO approach of developing a wearable device that could provide Magnetic Resonance Imaging (MRI) level details in the bodies or brains of wearers. For seniors, this means not having to frequently undergo expensive procedures and receiving more knowledge about their conditions without the discomfort of being surrounded by large scanning machines and at a much lower cost. Another device is the Gyenno ‘Smart Cup’ for Parkinson’s patients, allowing them to use cups independently despite the tremors they may be experiencing. Sensors detect and help counteract the action of tremors to keep the cup steady. Similar spoon and fork products, although not necessarily true IoMT devices, are also available from Gyenno as well as LiftLabs. These products can help seniors become independent, and help reduce, at least partly, the costs of constant care support.

Most of these approaches are still being developed but as they increase in sophistication, they have the potential to result in significant healthcare cost savings for the healthcare industry.
