8 mins read

IoT in healthcare or IoHT is the prime example of how businesses and industries are making profound use of the technology of the Internet of Things.

In short IoT, it is the ability of non-living objects and devices to connect, communicate, and share data across a common network for better performance.

For example, remotely controlled smart appliances such as vacuum cleaners, ACs, or geysers. Or app-enabled gadgets such as your smartwatch or other wearables.

With round-the-clock access to your data from your past and present, IoT devices can make better suggestions and offer plenty of remote features including automation.

Having instant access to real-time data and the ability to respond immediately makes IoT a rather useful technology in the realm of virtual healthcare and telemedicine.

Wasting no time either, the healthcare sector is all-in when it comes to using the Internet of Things.

What is the Internet of Healthcare Things (IoHT)?

There are many examples of IoT applications that make IoHT or the Internet of Healthcare Things as a whole.

For instance, patients use wearables such as smartwatches and fitness bands or trackers to obtain better results about their vitals and stats on the go and make necessary changes if needed.

Doctors & physicians on the other hand can access that data right from their phones, apps, and cloud platforms and provide instant remote support if required.

As far as hospitals and medical institutions are concerned, the scope of IoT systems is rather large and significant.

Importance of IoT in Healthcare

The professional healthcare industry, as we all know, is based on non-stop science and technological innovations.

There are several benefits of IoT for patients, doctors, and hospitals alike. Some of these applications even include health insurance companies and research businesses on a bigger scale.

From sensor-based objects and devices to monitoring equipment of all kinds, data collection and analysis to remote access to patient’s health, and real-time location of medical equipment and the staff, IoT-based healthcare solutions offer plenty of other advantages.

How IoT Helps in Healthcare?

Similar to any other field, the process of IoT in healthcare is the same.

That is, after the deployment of interconnected devices such as the IoT healthcare sensors, monitors, detectors, cameras, etc, has taken place, here’s how it goes:

Step 1: Data is collected by the sensors present in IoT devices.

Step 2: Data is then analyzed using smart AI algorithms and machine learning techniques.

Step 3: Data is transmitted across the server or cloud platform with meaningful insights.

Step 4: Based on the insights, doctors can make well-informed, actionable decisions and healthy recommendations for their clients.

Key Benefits of IoT in Healthcare

IoT is being used by the majority (86%) of healthcare organizations in some way or another. Close to 1/3rd of all IoT devices are used in the healthcare industry alone. Here’s why:

1. Remote Patient Monitoring (RPM)

Perhaps the biggest advantage of integrating IoT in healthcare is for patients who are located in remote or rural areas and do not have access to high-end medical services.

As a whole, IoT-enabled devices such as fitness trackers and health apps offer instant ability to doctors and physicians to monitor patients’ health and intervene accordingly.

2. Personalized Care

Having 24/7 access to patients’ conditions and states, doctors, clinics, and hospitals can provide better care that is tailored to individual needs.

3. End-to-End Connectivity

Seamless connectivity between different medical devices and systems allows patients, doctors, and everybody involved to be on the same page when a diagnosis or treatment is ongoing.

4. Telemedicine and Virtual Care

Based on the possibility of providing healthcare over the phone or internet, telemedicine and virtual care, in particular, can take a lot of help from IoT to provide their services remotely.

5. Medication and Prescription Management

Online prescription refills, smart pill dispensers, and app alerts about taking medications on time are some of the crucial advantages of IoT-enabled healthcare systems.

6. Infection Control

While the world is almost out of Covid-19, the clouds of another pandemic might just be on the horizon.

Apart from protecting healthcare workers and patients from catching infections, IoT devices can also help predict the contagiousness of a disease and monitor cleanliness, air quality, and the movement of the people in a healthcare facility.

7. Data Collection and Analytics

Advanced data analytics is the key to making the most out of IoT devices.

Having access to real-time patient data helps hospitals and doctors to understand the conditions better and make well-informed decisions about the diagnosis and treatment.

8. Higher efficiency and cost-cutting

By automating and streamlining many of the tasks and workflows, healthcare facilities can focus on providing the best of their services to patients at hand. Thus, reducing the overall cost of attending to more patients at once.

9. Data-driven decisions

IoT systems are known for their smart data analysis as can be seen with fitness and sleep apps.

In a medical setting, having meaningful insights about a patient’s conditions and vitals is all the more important to provide better data-driven healthcare decisions.
