The Transformative Impact of IoT in Healthcare

The ability of IoT medical devices to gather and analyze massive amounts of real-time data holds huge potential for refining healthcare practices and bringing medicine closer to patients. IoT replaces part of the visits to the doctor with telemedicine solutions and online consultations, saving time and costs. Patients don’t need to go to the hospital without special necessity and spending hours in queues. Instead, they can easily and conveniently get consultations and treatment online and even do medical tests remotely. 

Due to IoT technology, doctors and medical personnel can view and analyze patient reports, ongoing treatments, and medical histories to provide more personalized and effective care. 

Generally, all sorts of patient monitoring systems equipped with IoT sensors continuously track health conditions and provide real-time health status. If certain parameters go beyond the norm, they can communicate with other devices to take necessary actions that would help save someone’s life. At the same time, this data is sent to the cloud so that doctors can swiftly respond to an emergency situation and provide timely care.

Besides improved patient outcomes, the application of IoT in healthcare increases the productivity of medical staff and streamlines hospital workflows. Modern IoT applications help better manage patient data, schedule appointments with physicians, and automatically send health notifications and reminders to patients. So, the game-changing impact of IoT in healthcare is real and beyond doubt.

Impact of IoT in Healthcare

Applications of IoT in Healthcare

IoT reshapes traditional, old-fashioned treatment practices, offering new approaches and opportunities to remove shortcomings in the healthcare system, like outdated processes, supply chain inefficiencies, and lack of interoperability. We’ve picked the most impactful IoT applications in healthcare capable of driving positive changes in the sector.  

Smart Medical Devices

Patients suffering from chronic diseases such as diabetes, asthma, or hypertension can enjoy the benefit of IoT in healthcare through wearable devices that monitor corresponding health metrics. These devices, ranging from fitness trackers and smartwatches to temperature and smart blood pressure monitors, collect essential data such as oxygen levels, blood pressure, and heart rate. This information offers insights into how lifestyle impacts their condition, helping individuals make healthier choices. Upon detecting irregular health indicators, wearables alert users to potential problems and recommend how to deal with them.

Smart Medical Devices

Glucose monitors, blood pressure cuffs, and other home-based IoT devices, for example, can automatically record readings and send this information to healthcare providers. This real-time data enables doctors to alter treatment plans and make medication adjustments, often without the need for an in-person visit.

IoT healthcare companies continuously work on improving devices to make them more accurate and user-friendly so that patients of all ages can easily introduce them into their daily lives.

Hospital Operations and Asset Management

IoT helps medical personnel spend less time on management and routing tasks. Asset tracking is an area that can benefit a lot from applications of IoT in the healthcare industry. IoT-enabled devices monitor the location and status of basic supplies and expensive medical equipment like wheelchairs, defibrillators, and portable monitors. Although it might seem mundane, knowing the status and location of items can minimize costs and efficiency losses, especially when staff are overburdened and unable to find the necessary equipment. IoT can save time, resources, and potentially lives when deployed properly.

Energy management that is more sustainable and efficient is possible thanks to IoT. Imagine how much energy and operational costs hospitals can save with smart sensors and meters that control lighting, heating, and air conditioning systems in real-time. In doing so, healthcare facilities can help create a greener healthcare infrastructure.

Managing patient flow, especially during peak times, is not an easy task, but IoT can help here, too. Hospitals can better manage patient admissions by using IoT devices for patient flow optimization, minimizing waiting times and overcrowding, which improves patient experience.

Telemedicine and Remote Monitoring

Smart connected devices can constantly monitor patients’ vitals, such as heart rate, blood pressure, glucose levels, and more, outside the hospital setting. This is a true relief for chronically ill patients who now don’t need to visit hospitals frequently for routine checkups. Most of their follow-ups, as well as the continuous oversight over their health conditions, can be well managed remotely.

Remote Patient Monitoring

While nothing can replace face-to-face experience, doctors can track patient’s conditions through remote patient monitoring tools and provide medical advice through video consultations. A continuous flow of relevant information allows for personalized care plans, as physicians can adjust treatments based on the received data. Telemedicine solutions offer convenient online consultations for those living in remote areas and elderly patients while also easing the load on healthcare facilities.

Medication Management

Adherence to prescribed drug regimens can mean the difference between recovery and relapse. This challenge has been addressed by an IoT application in healthcare: wearables and devices that remind patients to take their medications on time. For example, smart pill bottles have sensors to track when the bottle is opened and send patients notifications if they miss a dose. Caregivers can also receive alerts on a patient’s missing dose to provide timely support and ensure the continuity of care. By analyzing the patient’s compliance history, doctors can understand the effectiveness of prescribed drugs and adjust treatment plans.

IoT in Healthcare: Real-life Examples

IoT in medical services allows for improving customer experience and saving time. So, it’s not surprising that many companies invest in IoT technology to develop software and devices to bring even more convenience, simplicity, and accessibility to the sector. We have selected the IoT in healthcare examples that have found wide use and made patients’ lives comfortable. 

  • Kinsa Smart Thermometers collect information on individuals’ temperature and send it to a mobile app via Bluetooth. The application keeps the history of temperature records and can thus help identify health trends and potential outbreaks. 
  • Inspiren’s iN Ecosystem. This system intends to improve patient experience and their stay in the hospital. It uses a network of sensors, analytics tools, computer vision, and other technology to track various factors such as room visits by staff, patient movement, and even the time since the last interaction with a healthcare professional. Thus, their IoT-based ecosystem helps create more responsive and attentive care experiences.
  • Dexcom Continuous Glucose Monitoring (CGM) System is an IoT device that provides real-time glucose level monitoring for diabetes management. It consists of a small sensor that measures and wirelessly sends glucose readings to a smart device, alerting users to potential episodes of hypoglycemia or hyperglycemia that require quick corrective actions.
