Traditional medical care is experiencing a dramatic shift as digital transformation gives patients better access to medical care facilities even in the most remote areas. [1] Most of the conventional healthcare utilize manual management and maintenance of patient demographic data, diagnostics, case history, medication, drug stock maintenance, billing that results in human errors and can considerably impact the lives of patients. [2]
Internet of things (IoT)-based smart healthcare aids to overcome such human errors. It also assists the doctors in accurate diagnosis of the disease by interconnecting all the vital parameters monitoring devices over a network with a system for decision support. Those medical things that have the facility for transferring data over a network without demanding human to computer or human to human interaction are known as Internet of Medical Things (IoMT). [2]
IoMT, a subcategory of IoT, plays a vital role in the field of healthcare and its impact on the healthcare market is irreversible and undeniable. [3,4] Such solutions can help to overcome the common challenges witnessed in medical settings. [5] Paired with smartphone apps, the emerging technology of IoMT enables patients to send their health information to medical caregivers. [6] IoMT devices are connected to medical care provider networks and transmit their data to internal servers or cloud repositories. [7]
For both patients and doctors, IoMT assists in better surveillance of diseases and play a fundamental role in tracking and preventing chronic illnesses. [6] Let us dive a little to explore how IoMT has revolutionized and transformed the healthcare experience.
What is IoMT?
Before discussing the benefits of IoMT technology for the healthcare sector, let us first understand what exactly IoMT is?
IoMT is an amalgamation of medical devices, hardware
infrastructure, and software applications that are utilized for connecting
healthcare information technology by using networking technologies. [3]
The smart system of IoMT primarily consists of smart sensors and electronic circuits for acquiring biomedical signals from a patient. It also comprises a processing unit for processing the biomedical signals, a network device for transmitting the medical data over a network, a temporary or permanent storage unit, a visualization platform with artificial intelligence plans for taking appropriate decisions as per the convenience of a clinician. [2]
Benefits of IoMT
for healthcare sector
Using IoMT yields a myriad of advantages and certainly,
there is even more to be unveiled. Below are a few benefits of IoMT:
How is IoMT impacting healthcare?
Affordable medical care services are the need of the hour. With their promising ability to generate, collect, analyze and transmit health data or images, IoMT technology is expeditiously altering medical care delivery. [6]
(a) In-home IoMT
The in-home segment includes the following:
1. Personal emergency response systems (PERS):
It includes wearable device/relay units and a live medical call center service for offering security and boosting self-reliance for people at high risk (like homebound or limited-mobility senior citizens) that want to live at home without compromising their safety. It enables users to promptly communicate and get emergency medical care. [1] For instance, PERS can track events like a heart attack to automatically call for assistance. [3]
2. Telehealth virtual visits:
It includes virtual consultations that assist patients to handle their conditions and getting prescriptions or the recommended healthcare plans. Examples include video consultations, and assessment of lesions or symptoms through digital tests and video observation.
3. Remote patient monitoring (RPM):
RPM is valuable in the following management areas:
(b) On-body IoMT
It is the utilization of wearable devices that are connected to the remote monitoring systems. Contrary to in-home IoMT, on-body IoMT can commonly be utilized outside of the home as individuals live their normal lives. [3] They can be broadly divided into consumer on-body IoMT devices and clinical on-body IoMT devices.
(1) Consumer on-body IoMT
devices:
They are wearable medical devices that a person can buy for tracking health metrics for both personal usage and for sharing with the caregivers. [3] The majority of these devices are not regulated by the healthcare authorities. However, on the basis of consumer studies and informal clinical validation, experts can endorse such devices for particular health applications. [1] Besides monitoring a standard metric (like heart rate), these smart devices can be early warning signs for more severe health problems. For instance, an Apple Watch can alert a person about irregular heart rhythms. [3]
(2) Clinical on-body IoMT devices:
They encompass regulated devices and supporting platforms which are usually certified/approved for usage by 1 or more regulatory or health authorities. The majority of these IoMT devices are used in conjunction with the expert advice or prescription of a clinician.
Examples include:
(c) Community IoMT
It is the usage of IoMT devices and tools throughout a
broader geographic area. It includes five components:
For instance, sensors can be used in pharmaceutical shipments for monitoring pressure- or temperature-sensitive shipping containers. This helps in ensuring that the quality is sustained throughout the shipping process. [1,3]
(d) In-Hospital IoMT
This segment includes the following areas:
1. Asset management: IoMT aids in monitoring
and tracking of high-value capital equipment and mobile assets (like
wheelchairs and infusion pumps), throughout the facility.
2. Personnel management: It assists in the
measurement of efficiency and productivity of medical care staff.
3. Patient flow management: It leads to improvement
in facility operations by preventing bottlenecks and improving patient
experience. For instance, Using IoMT, the arrival time of a patient from the
surgery room to post-care to a wardroom can be supervised.
4. Inventory management: It aids in streamlining
ordering, storage and usage of hospital supplies, consumables, medical devices,
and pharmaceuticals. This minimizes inventory costs and enhances staff
efficiency.
5. Environment (such as humidity and temperature) and
energy monitoring: It helps in
overseeing electricity usage and ascertains optimal conditions in patient areas
and storage rooms.
Innovative devices include:
Advancements in technology are transforming our lives and providing smart solutions for every sector. One such sector is healthcare. The utilization of IoMT concepts and tools has substantially altered the healthcare services. [9] The connectivity between devices and sensors is an innovative way to streamline clinical workflow management and ultimately head to a comprehensive enhancement in patient care. [6]
These internet-connected devices improve therapeutic efficiency, minimize costs of care and drive better outcomes in the field of medical care. [6] Due to the nature of IoMT networks, communication security is one of the most crucial elements to ensure the privacy and security of a patient. [7] IoMT is poised to evolve the future of healthcare. [6]
In the future, even the most remote areas will benefit from
improved access to care, as the connected medical devices continue to discover
their way into the hands of both doctors and patients. The evolution of the
IoMT ecosystem is paving the way for other novel technologies too. It is
anticipated that implementing IoMT would lead to more accurate diagnosis, and
fewer mistakes, at reduced costs. [7] Irrespective of a patient’s location or
condition, the evolution and expansion of the IoMT ecosystem will indeed become
more impactful. [6]
