We can also say that IoT is a concept built around the method of full ubiquitous computing, which is the processing of information associated with an external object or activity. Ubiquitous computing consists of the interconnection of electronic devices equipped with microprocessors and radio sensors, which help them to communicate with each other and exchange vital information.

IoT in the healthcare sector is indeed an example of this omnipresent computing. For example, thousands of intelligent IoT electronic devices can be installed at a hospital, which can monitor patients’ health status around the clock, interact with each other, make informed decisions, and transfer the information to a Cloud platform.


How IoT Works In Healthcare?

In general terms, an IoT device could be considered as a device with a sensor/radio, which can interact with the physical world and transmit information with the help of the internet. Such devices can capture different types of patient information or receive inputs from healthcare professionals. Here an example is a CGM (Continuous Glucose Monitoring) for insulin pens, which works to capture and transmit the data of diabetic patients. 

How IoT Works In Healthcare

IoT devices create an ecosystem, where they communicate with each other, and help healthcare professionals to take critical actions to help their patients, or even save their life. For example, an IoT wearable device can take an intelligent decision to contact the healthcare facility, if an elderly patient is experiencing any health-related emergency.

IoT devices keep on collecting the passive data and then send this information to the cloud, which helps healthcare professionals to make informed decisions. They can either simply view the patient status or can call an ambulance or initiate an emergency protocol if required.

IoT Workflow Process for Healthcare

IoT devices operate in the following fashion:

  • An IoT device contains a sensor, that collects data from patients, or it can capture the data input from doctors/nurses. 
  • Then IoT device utilizes AI-driven algorithms like Machine Learning to analyze the collected data.
  • Then the IoT device decides if it needs to act on the given information or just send it to the cloud. 
  • IoT devices provide valuable information to doctors, healthcare professionals, and robots so that they can make informed and actionable decisions.

IoT Workflow Process for Healthcare

Though here it is important to understand that not all IoT devices contain sensors, they need at least a radio and TCP/IP address, that can help them communicate via the Internet.

We can combine IoT with Artificial Intelligence technology, to avail the benefits of data analytics, which offers vital information to determine preventative medicine for patients.

Less Risk of Errors and Miscalculations

Medical treatment and medicine development allows almost zero margin of error, though sometimes it is not achievable due to the involvement of human, as human errors do occur. Sometimes, doctors may take the wrong measurement or conclusion, sometimes healthcare professionals may mix up the test results.

Such errors due to human factors can lead to some serious consequences. However, with IoT usage, such errors could be avoided with adequate checks and balances in place. Human experience coupled with Machine intelligence can certainly enhance diagnostic accuracy.

Enhanced Mobility of hospital resources 

This is among the biggest benefits IoT offers, that can make a huge difference for the front-line staff of any hospital. In times of the COVID pandemic, patients need immediate attention from healthcare staff, who are already overworked and contributing beyond their usual capabilities. Healthcare staff needs technology and tools, that can help them track hundreds of patients in real time.

An IoT-based tracking system can help them get vital alerts if there is any critical change observed in a patient’s parameters so that they can immediately locate the patient and administer the necessary treatment.

Better Drug management and adherence 

IoT-aided medical applications can assist doctors and other healthcare professionals in remotely determining if a patient has taken drugs or not.

In case of non-adherence, the staff can call and remind the patient about the drug schedule. This whole process could be automated as well, which makes it more efficient and cost-effective, and of course, it will reduce unnecessary human involvement and several other overheads.

Healthcare app development

End-to-end connectivity and affordability 

The IoT in healthcare applications can use the latest communication technology to improve data connectivity and sharing.

The medical reports of patients such as ECG reports, blood sugar level reports, and X-ray scans can be stored in the Cloud and could be accessed with a mobile device remotely.

Deep Research in Healthcare 

The Internet of Things plays an important role in the deep research of medicine and other healthcare areas. With the help of IoT, we can capture the data and then research the given data.

A recent example is COVID-19 vaccine development, where IoT applications were used to perform deep research on different variants in a very short period. IoT devices can transmit the data across all geographic locations within a fraction of a second, this makes it easy to share the research data without having the further cost and technical overhead. 

IT Integration & Cyber-Security in Healthcare 

Hospitals store massive data files which are crucial for patient care and required from time to time. As the data is confidential and related to the patient, hence cyber-security is a big concern to keep the data secure from any sort of attacks and breaches. IoT-based cloud servers are adequately protected by next-gen systems, which makes it almost impossible for a hacker to breach the security firewalls.

The Future of Healthcare with IoT Technology

The applications of IoT in the healthcare and medical sector are quite abundant and it also involves a wide range of technologies and tools.

Another challenge could be the compatibility between different devices connected through the IoT networks, as any sort of compatibility issue may impact the process of data transfer, analysis, and retrieval.

IoT System Cost

We know that IoT will help organizations to save huge amounts as far as the cost of treatment and time is concerned. However, the initial investment to procure the IoT devices for the healthcare sector is certainly a big challenge, as hospitals must invest thousands to a few million USD to set up a basic IoT device infrastructure in their facilities. Apart from that, the management and support for such an IoT-based system are quite costly now.

Challenges of IoT in Healthcare

Data Security and Privacy 

With the emergence of technology, user data has become vulnerable to all sorts of security and privacy concerns, hence we can say protecting data privacy and making the infrastructure secure is among the biggest challenges for IoT. The IoT mainly operates on the transfer and storage of a massive amount of user data, and any data breach can have unpredictable consequences for users and hospitals.

The data could be misused, could be sold to unauthorized people, hackers can create fake IDs to procure prescribed medicines and other stuff and then misuse them. Data breach and misuse could cost millions of USD in legal obligations; hence this is a big concern and should be addressed properly while making an IoT-based system.

Database Cost and Management 

IoT works on a massive amount of data, and Doctors or hospitals are storing this data which puts pressure on the existing IT infrastructure and Database systems. It put cost and management constraints on the healthcare service provider. With the increasing number of patients, the data will obviously scale up, and it will increase the cost of an additional database system, also not managing the database efficiently may lead to data loss or manipulation, which could pose a risk to a patient’s life and hospital’s reputation.

healthcare app development


The Internet of Things has emerged as a technology, which can help us find solutions to many day-to-day problems in almost every possible sector. If we talk about the Healthcare sector, then there is no doubt that IoT technology is unstoppable and growing in leaps and bounds, despite its limitations and challenges.
