Healthcare providers connected with patients via video conferencing and voice-over calls to avoid in-person meetings and thus prevent themselves from contagious disease.

The Telehealth Explosion and Virtual Care Will Remain Mainstay

Post-pandemic, virtual care will likely remain a mainstay and is anticipated to get adapted more by small-town practitioners and health workers. With the wide acceptance by physicians and patients, in-person visits for routine follow-ups and reports feedback would be drastically eliminated. As telehealth expands, physicians, hospitals, and other clinical will make a shift towards IoT-powered devices and applications to collect, analyze and monitor patients’ data in real-time scenario.

In this article, we will take a closer look at the Internet of Things (IoT) for healthcare, its advantages, challenges, applications, and a lot more. So, let’s deep dive to know more.

What exactly is IoT and why it plays a crucial role in the healthcare segment?

IoT is a concept built around the idea of ubiquitous computing where the information processing is linked with external objects or real-time activity. It involves the connection of devices with microprocessors and sensors to communicate and pass data to the cloud.

When it comes to omnipresent computing, nothing is better than considering IoT in the healthcare industry.

For example, innumerable intelligent devices can be connected and set up in hospitals and nursing homes to monitor patients’ health 24/7, communicate and send information to each other to make the decision-making process streamlined and easy, and upload the same information to the healthcare cloud platform. It not only enhances the productivity of healthcare workers but also automates the task and reduces manual resource involvement.

How IoT can be used in healthcare effectively – Real Time Examples

Let’s understand how IoT powered devices to aid the healthcare industry to automate the task and streamline operations with the below examples:

  • With the help of connected devices, one can analyze, and upload real-time patient information to the cloud right from ambulance, home, office, anywhere.
  • Since medical devices are well-equipped with the self-maintenance system, IoT healthcare device will find out their components, identify low thresholds, and communicate with medical assistants and manufacturers as and when needed.
  • With the help of IoT and wearables, patients taking home care and elders can directly communicate with healthcare workers.
  • The upsurge of telemedicine is all due to IoT. With IoT-powered devices, the patient can be observed and treated digitally through electronic actuators and a video conferencing system.

IoT in Healthcare – Benefits

1. Quick reporting and monitoring

By performing real-time monitoring of a patient’s health condition, all information and required health data is collected in the smart medical device interconnected with a smartphone app. Later, the smartphone data connection is used to transfer the collected information to the cloud platform or directly to the physician for quick and accurate decisions.

A study conducted by the Centre of connected health policy indicated that a 50% reduction was noticed in heart failure patients in the 30-days readmission rate due to remote patient monitoring.

Thinking how these devices would be serving multiple endpoints?

Here you go: The IoT devices collect and transfer the health data including oxygen level, sugar level, blood pressure, weight, ECG, and more to the cloud platform. At a later stage, this information is shared with an authorized person who could either be a physician, medical insurer, health firm, or consultant so that they can have a glance over the collected data on their device and at their convenience.

This approach not only streamlines the operation but also reduces the mortality rate to a great extent.

2. End-to-end connectivity & affordability

Introduction to healthcare mobility solutions, latest IoT technologies, and next-gen health care facilities prove to be of immense help in automating the patient care workflow.

Talking about the connectivity protocols – ZigBee, Wi-Fi, Bluetooth LE, Z-wave, and other modern protocols and healthcare personnel have transformed the way they spot illness and ailments in patients and have found a revolutionary approach to treat patients across multi-healthcare fields.

This tech-driven healthcare setup lowers the healthcare cost by eliminating unnecessary doctor's visits, making optimum resource usage, and improving resource allocation and planning.

3. Real-time tracking & alerts

When the conditions are critical, on-time alerts are quite essential. These medical IoT devices understand the signs of any diseases and pass the signals data to doctors in real-time scenarios along with dropping notifications to concerned people via notification and smart sensors.

These real-time reports and alerts are useful to give an opinion about the patient’s condition regardless of place and time. It also helps healthcare providers to leverage on-time treatment and make accurate decisions.

These IoT-based devices having capabilities like real-time alerting, tracking, monitoring allow doctors to give hands-on treatment with better accuracy along with remote improving patient care systems.

4. Remote medical assistance

At times of emergency, smartphones have become the way to connect with patients leaving kilometers away. With the introduction of mobility solutions in the healthcare system, doctors can treat the patients’ ailments on the go.

Apart from this, numerous IoT-based healthcare delivery chains forecast to build machines and systems to distribute drugs based on the doctor's description and ailment-related data linked through the device.

This further enhancement of IoT will improve patient care in hospitals and will cut down people’s healthcare expenses to a great extent.

Did you know: According to the CDC, 463 million adults have diabetes worldwide. In the United States alone, 34.2 million adults have diabetes, 10.5% of the population.

What’s the solution? – IoT based Glucose Monitoring System

For more than 30 million Americans suffering from diabetes, glucose monitoring has been difficult. Not only it seems inconvenient to check and record glucose levels manually but doing so would have a record of the levels checked during the time test was conducted. If in some cases a fluctuating level is noticed widely, periodic testing seems impractical.

IoT devices can challenge these issues by automating glucose level monitoring in patients. It thus eliminates the need to keep manual records and also alerts patients when the glucose level seems problematic.

What are the challenges faced in IoT based healthcare system?

1. Data security & privacy

One of the most significant challenges in an IoT-powered healthcare system is data security and privacy. Though IoT devices capture and transmit data in a real-time scenario, it somehow lacks data protocol and security standards.

The data ownership regulation is quite unclear with electronic devices. All these factors make the data suspectable and open for cybercriminals to attack the system and compromise on personal health information of doctors and patients.

It further alarms a threat to the entire health ecosystem as the health record can be misused to create fake IDs to purchase drugs and medical equipment’s which can be later encashed. This information can further be used to file a fraud claim in the patient’s name.

2. Integration of multi-devices and protocol

Integration of multiple devices can also cause hindrances in implementing IoT. The reason behind this is – the device manufacturer hasn’t reached an agreement regarding protocol and communication standards.

Let’s say if multiple devices are connected, the difference in their communication protocol and standards acts as a hindrance in the process of data aggregation. This non-uniformity of the connected device’s protocol slows down the entire process and thus reduces the scalability of IoT-powered healthcare systems.

3. Data overload & security

Due to different communication protocols and standards, data aggregation seems difficult to incorporate. Though IoT devices collect innumerable data which is used to gain vital insights but taking decisions based on these data is extremely difficult for doctors and staffing members since the data is huge. It eventually impacts the decision-making quality and leads to issues arising with patients' safety.

Moreover, this concern is rising as more devices are connected which record more and more data.

Applications of IoT in Healthcare
