The Role of the Internet of Things in Healthcare: Future Trends and Challenges


With recent advancements in the Internet of Things (IoT), the sector of healthcare has grown increasingly expanded. Physicians and hospital staff will execute their tasks more conveniently and intelligently thanks to the Internet of Things. There is an unparalleled possibility to improve the quality and productivity of therapies and the patient’s well-being and government funding, thanks to this technology-based therapy method.

What does it do

Intelligent traffic management, safety-aware autonomous driving, brilliant grid energy efficiency, remote patient monitoring, machine health monitoring, intelligent industrial automation, and intelligent home security systems are just a few of the applications enabled by IoT. IoT applications will transform how different industries function in Industry 4.0 and 6G connectivity.

These industries can use IoT in a variety of ways. It can help with intelligent energy usage and communication between devices and the grid. IoT can help drivers and passengers stay safe when using smart transportation. Similarly, IoT provides various potential benefits in inpatient health monitoring and early diagnosis in health care. IoT may also monitor the health of machinery in many industries, extending their lifespan and increasing their performance.

Internet of medical things

The Internet of Medical Things (IoMT) is a critical enabler for the future healthcare business. Remote patient monitoring, automatic monitoring of emergency patients, medical supply chain control, and contact tracing in pandemic circumstances are all healthcare applications services that IoMT can provide.

The sensed data in IoMT is linked to patient body factors like heart rate, blood pressure, and blood sugar level. A variety of sensors can also aid in the early diagnosis of severe disorders like cancer. In addition, infectious diseases can be diagnosed sooner, allowing for better control of their spread.

Long-range communication technologies, such as 5G, can control data dissemination in IoMT. The data, such as patient body parameters, must be regularly shared with the hospital monitoring room and reliable. Security while disseminating data becomes a significant concern in supply chain monitoring or contact tracing applications.

In the IoMT remote patient monitoring application, the evaluated data is about the patient’s health state. Can produce alarms in a sudden change in a parameter and notify doctors. Furthermore, it can continuously monitor the temperature of medicines or vaccines for supply chain monitoring.

Changing health systems

With the novel COVID-19 pandemic expected to effectively shut down traditional modes of health service delivery globally by 2020, efforts to reduce implementation barriers to technology-supported health delivery highlight the potential to reframe conventional models of care into virtual and distance modalities. Many countries have responded by successfully implementing technology-assisted services to maintain healthcare practices and social space.

As world leaders consider policies that could expand access to technology-assisted health services in response to (and after) the current COVID-19 crisis, it’s becoming more critical to understand how established and emerging IoT technologies can help health systems deliver safe and effective care in either a complementary or alternative manner during times of crisis or epidemics.

Advantages of IoT

At the individual level, IoT provides the chance to connect and potentially learn from non-health IoT technology to track everyday activities, provide information support, and encourage behavior change. Furthermore, IoT and data linking open up many possibilities for transparent, evidence-based decision-making, which might help shift disease trends and improve citizen well-being at a large scale.

The combination of urban infrastructures, IoT technology, and cloud computing enables the collecting and analyzing a massive amount of human and nonhuman data. For example, during the global COVID-19 pandemic in Taiwan, Successfully used big data analytics applied to electronic community data (GPS, closed-circuit television surveillance, and credit card payments) and personal mobile data decision-makers will make evidence-based decisions in supporting healthy social and built environments, safe transportation systems, high-quality public services, and competent health care and emergency response systems thanks to the Internet of Things and data linkage.

Barriers for IoT based healthcare

There is a disconnect between public knowledge and comprehension of data security in cloud-based health records. This is concerning because it represents the single greatest societal danger to IoT adoption. The possibility of a data breach may never go away; nevertheless, the perceived value to customers must transcend these worries for consumers to trust IoT-enabled health infrastructure.

IoT could open the door to hacks and the unauthorized collection of personal data. applications of iot in healthcare are vulnerable to cyberattacks for two reasons: (1) most communications are wireless, which makes eavesdropping very easy, and (2) most IoT components are energy-constrained, making them unable to execute elaborate security systems on their own.
Data sharing across states or territories, as well as worldwide, is another critical concern.

The federal government should ensure data control and storage privacy, security. And confidentiality, but multinational hosts and suppliers may not be obligate to adopt any such rule.

As a result, developing and implementing effective IoT-based health care policies. And models of care necessitates strategic planning and open practices. Interoperability, of which several frameworks exist, is critical to IoT-enabled health care’s future and full potential. Achieving interoperability across IoT platforms can provide a safer, more accessible, productive, and pleasant experience for clinicians and patients alike.

Future opportunities and challenges

The Internet of Things (IoT) is a network that enables intelligent health services to function. Data analytics and competent health care are enable when health data is collect, share. And store by IoT sensors, improving risk factor identification, disease diagnoses, treatment, and remote monitoring and empowering people to self-manage.

We are seeing virtual models to transfer treatment from hospitals to the home through sensors. And equipment that allow remote review and monitoring of patients in their homes or hospitals and provide a continuum between these through cloud access. More recently, governments and policymakers around the world have (at least temporarily) removed implementation. And remuneration barriers to allow health care professionals to use virtual models of care for people who need. It as part of the 2020 public health efforts to mitigate the spread of COVID-19.


IoT also can improve the quality and efficiency of the complete service delivery ecosystem, including hospital management, medical asset management, staff workflow monitoring, and medical resource optimization based on patient flow.
