Benefits of Internet of Things in Healthcare

The implementation of IoT solutions has undoubtedly improved the healthcare industry, so it has become one of the most useful tools medical professionals have at their disposal.

Read on to see some of the positive impacts this technology has on patients, medical staff, and hospital administrators.

Benefits for Patients

Here are some of the positive things IoT brings to those in need of medical assistance:

  • Continuous Monitoring of Medical Conditions

Remote patient monitoring has been one of the biggest advancements in the healthcare industry in the past few decades. Patients with chronic conditions such as diabetes, asthma, and cancer can now get wearable or surgically implanted devices that monitor their condition.

An IoT smart device can, for instance, constantly monitor diabetics’ blood sugar levels and automatically administer doses of insulin when required.

  • Automatic Transmission and Analysis of Data

IoT medical devices can transmit patient data they gather automatically, which makes them indispensable diagnostic tools.

For example, patients suffering from heart disease can wear a smart device that monitors their condition while they perform their regular daily tasks. This device provides doctors with all the data necessary to diagnose and treat those conditions properly.

  • Remote Consultations

Patients can contact their doctors for a consultation without ever leaving the comfort of their home, as a doctor has real-time access to all the essential data. Smart healthcare devices that enable this type of patient care will become more common in the coming years.

  • Automatic Reminders

Automatic reminders for medication and appointments are a true game-changer, especially for elderly patients. These devices can make forgetful patients’ lives much easier.

Benefits for Medical Staff

Medical professionals can do their jobs more efficiently and effectively, thanks to healthcare IoT devices. Here are some of the benefits IoT tech has brought them:

  • Easy Access to Patients’ Medical History

As medical technology grows, it will become easier for doctors to treat new patients. Transferring from another hospital or, even worse, another country used to cause many problems when medical records were kept on paper. But with connected medical devices, doctors can share vital medical information safely and securely.

  • Easy Access to Patients’ (or Devices’) Location

Another important use of this technology in geriatric care is equipment tracking. It’s common for patients who have Alzheimer’s or dementia to become confused and get lost.

However, if they’re wearing a smart device, it will be much easier to locate them. Medical professionals can ensure people’s safety thanks to patient tracking and IoT healthcare applications.

  • Quicker and More Accurate Diagnoses

Even the best doctors can misdiagnose a patient. Luckily, some smart devices run complex algorithms that can detect abnormalities, reducing the chance of human error in medical treatment.

Benefits for Non-Medical Staff

(Management and I.T.)

The Internet of Things benefits all healthcare departments, even the non-medical ones. Here are some examples of how managerial and IT departments use this technology to optimize their workflow:

  • Analysis and Control of Resource Consumption

Every hospital administration in the world wants to cut costs. By using IoT, administrators can track the use of both medical and non-medical resources.

For example, hospital management can track and analyze electricity consumption and decide which parts of the facility need more or less heating, cooling, or lighting. This shows that the Internet of Medical Things isn’t useful only to doctors and patients.

  • Security and Protection

Hospitals around the world are starting to rely more and more on IoT security and protection devices. Smart alarms, motion sensors, and camera systems are being implemented to increase patients’ and staff members’ safety.

  • Preventive Maintenance

Another great advantage of IoT is that it can help prevent fatal equipment failures. IoT healthcare networks automatically share the data they’ve gathered, including information on bugs or hardware failures, making life a lot easier for the maintenance team. By identifying failures in advance, devices can protect themselves and patients from harm.

  • Fast Data Transfer

The ability to quickly send or receive patient data can sometimes make the difference between life and death. Having quick access to essential data, such as disease history and allergies, has become the norm with connected healthcare.

  • Automation

One of the most cost-effective IoT benefits for hospital administrators is automation. Some processes can rely on automation, which reduces hospitals’ need for staff. Buying and maintaining a cleaning robot that resembles a Roomba is far cheaper than paying a full-time janitor’s salary.

Internet of Things Examples

Millions of people around the world have become dependent on these devices. People who used to need constant care due to their conditions can now relax in the comfort of their homes while medical professionals monitor their health remotely.

Here are 10 examples of these devices, the illnesses they help with, and the companies that manufacture these medical IoT devices:

1. Apple Watch and Parkinson’s disease

2. Google Smart Contact Lenses and Diabetes

Believe it or not, even some contact lenses are connected to the internet these days. The concept of smart contact lenses was an optimistic one; this new medical technology was designed to measure tear glucose levels, allowing people with diabetes to track blood sugar.

Google partnered up with Novartis for the project, but the suggested glucose monitoring method was quickly discarded as untrustworthy by researchers. The company has since changed the smart lenses’ purpose to treating eye defects, such as long-sightedness and cataracts.

Sensimed, a company based in Switzerland, is working on a similar project: glaucoma prevention through automatic monitoring of eye dimensions.

3. Proteus Digital Health Ingestible Sensors and Hypertension, Diabetes, and Mental Health

A World Health Organization study has found that around half of all prescribed medications are not taken as per doctors’ instructions. Proteus Digital Health has been working hard to reduce that figure.

The company is trying to achieve this goal by producing pills that dissolve in the stomach and send a weak signal to an external sensor. This information then pings users’ mobile app, confirming that they followed the proper consumption directions.

What makes this one of the most impressive items on our IoT healthcare devices list is the variety of patients these sensors can help. Everybody from patients with hypertension or type 2 diabetes to those taking antipsychotics could benefit from it.

4. CYCORE and Cancer

Presented in 2018 at the American Society of Clinical Oncology annual meeting, the CYCORE system consists of a Bluetooth-enabled weight scale, a blood pressure monitor, and a smart health app that tracks patient’s symptoms to gather data and send daily reports to the oncologist, who can alter the treatment as needed.

Users of this technology reported less severe cancer-related symptoms than those who visited their doctor weekly with no remote monitoring.

5. CGMs and Diabetes

Smart continuous glucose monitors (CGMs) have been used in the US since 1999. Internet of things medical devices like Eversense and FreeStyle Libre track wearers’ blood sugar levels and transmit them to a smart device, such as a phone, tablet, or watch.

The devices can then detect spikes and dips in blood sugar and administer medication accordingly. These remote patient monitoring devices are beneficial for parents with diabetic children or those caring for elderly patients.

6. Insulin Pens and Diabetes

By connecting to the patient’s phone using a smartphone app, newer models of insulin pens record data on when each dose is administered, the type of insulin used, and the quantity of the insulin injected.

This data helps doctors determine parameters for future use, increasing the overall effectiveness of the treatment. The most popular smart insulin pen devices include products like Gocap, InPen, CLIPSULIN, and NovoPen.
