Before the (Internet of Things) IoT in healthcare, patients could only interact with doctors during visits or through calls, making continuous health monitoring difficult. IoT devices allow healthcare providers to track patients’ health remotely, ensuring safety and better care. This technology enhances patient-doctor communication, leading to greater satisfaction. Additionally, remote monitoring can shorten hospital stays and reduce readmission rates, ultimately lowering healthcare costs and improving treatment outcomes.

Understanding IoT in Healthcare

In healthcare, IoT systems gather miscellaneous patient data and input from doctors and medical professionals. A great example is continuous glucose monitoring for insulin pens, which helps manage diabetes effectively. Moreover, these devices can communicate with each other to take important actions that can save lives. Once they collect data, the Internet of Things in healthcare sends this vital information to the cloud, allowing doctors to respond quickly.

In other words, IoT in healthcare can enhance patient health, boost the productivity of healthcare workers, and streamline hospital operations. By making information easily accessible, IoT can lead to better care and more efficient healthcare systems. 

Benefits of IoT in Healthcare

The Internet of Things (IoT) is a network of smart devices that can talk to each other. These devices can collect information, share it, and make decisions. Here, we’ll elaborate on the advantages of the Internet of medical things. 

• Personalized Care: Imagine having a doctor who knows exactly how your body feels, even at home. IoT devices can track your health and send that information to your doctor.
• Faster Diagnosis: IoT devices can quickly check your heart rate, blood pressure, and other important things, helping doctors diagnose problems faster.
• Early Detection: IoT can spot tiny changes in your health before they become big problems.
• Saving Money: It can help you and your doctor save money by reducing unnecessary hospital visits and tests.
• Better Treatment: The Internet of Things can help doctors create a treatment plan that's just right for you.
• Remote Care: You can get medical help from home using IoT devices.
• Robot Doctors: IoT helps robots perform surgeries with more precision.
• Stopping Fraud: With the help of the IoT, you can help find people who try to cheat the insurance system.
• Making Smart Decisions: IoT helps healthcare systems make decisions based on data.

Applications of IoT in Healthcare

IoT is changing healthcare. It's helping doctors do their jobs better and making it easier for patients to get the care they need.

Here are some ways IoT is being used in healthcare:

• Reducing wait times: IoT can help hospitals track patients, staff, and equipment to reduce wait times in the emergency room.
• Managing drugs: IoT can help ensure that hospitals have the right drugs on hand.
• Tracking important equipment: IoT can help hospitals track important equipment to ensure it's always available.

IoT has some applications of IoT in smart healthcare. These devices are making it easier for patients to manage their health.

• Hearables: These smart hearing aids can help people with hearing loss hear better.
• Ingestible sensors: These tiny sensors can monitor your body and warn you if there are any problems.
• Moodables: These devices can help improve your mood.
• Drones: Drones can be used to deliver medicine and supplies.
• Healthcare charting devices: These devices can help doctors record patient information more easily.
• Insulin pens and smart CGMs: These devices can help people with diabetes manage their blood sugar levels.
• Smart video pills: These pills can take pictures of your digestive system to help doctors diagnose problems.

What are the Challenges of IoT in Healthcare?

After understanding the benefits, we are moving ahead towards the challenges. 

• Keeping Data Safe: IoT devices collect a lot of personal information. Moreover, this data can be stolen by bad people. It's hard to know who owns the data and how to protect it.
• Talking to Different Devices: IoT devices from different companies don't always work together, making it hard to use them all together. In other words, It tries to talk to people who speak different languages.
• Too Much Data: IoT devices collect a lot of data. In addition, it's hard to make sense of all this data if there is too much data can make it hard to make good decisions.
• Cost: IoT devices and apps can be expensive to make. But, they can save you money in the long run. Moreover, IoT can help you save time, and money, and improve your business.

IoT Medical Device Examples

It's important to know how the Internet of Medical Things (IoMT) devices are used in healthcare to effectively monitor and protect them. The most common use is remote patient monitoring, where devices collect health data like heart rate and temperature. There are numerous ways in which healthcare IoT solutions are transforming the industry.

• Remote Patient Monitoring: This is the most popular use of IoT in healthcare. Remote health monitoring systems using IoT can automatically gather health information from patients at home, like heart rate and blood pressure, so they don’t need to visit a clinic. However, this data is sent to healthcare professionals who can analyze it and respond if something seems wrong. A key challenge is keeping this sensitive data secure.
• Glucose Monitoring: For people with diabetes, checking glucose levels can be a hassle. IoT devices can continuously monitor glucose levels, alerting patients when their levels are too high or too low. The challenge is to make these devices small and energy-efficient.
• Heart Rate Monitoring: Monitoring heart rates can be tricky, especially in hospitals where patients are often wired to machines. Small IoT devices now allow patients to move freely while still keeping track of their heart rates accurately.
• Hand Hygiene Monitoring: Ensuring proper handwashing in hospitals is crucial to prevent infections. In fact,  IoT devices can remind staff and patients to sanitize their hands and provide instructions, helping to reduce infection rates significantly.
• Depression and Mood Monitoring: Collecting data on a patient’s mood has been difficult. IoT devices can analyze physical data, like heart rate, to infer a patient’s mental state. While not perfect, these devices can help track mood changes more effectively than traditional methods.
• Parkinson’s Disease Monitoring: For patients with Parkinson’s, it’s important to track how their symptoms change throughout the day. IoT sensors can continuously collect this data.

Some Real-world Examples of IoT in Healthcare

It's expected to grow by 37.6% each year. IoT helps in many ways. However, it's making healthcare better and easier.

Here are some examples:

• Smart Contact Lenses: These lenses can read blood sugar levels in people with diabetes.
• Tracking Devices: You can track things like wheelchairs and medical equipment to find them easily.
• Wearable Devices: These devices can track things like heart rate, and steps, and even help with depression.
• Medication Reminders: Devices can remind you to take your medicine and even help you get the right dose.
• Medical Alert Systems: These systems can call for help if you have an emergency.
• Heart Monitors: These devices can track your heart and alert doctors if you have a problem.
• Activity Trackers: These trackers can help doctors understand your health better.
• Glucose Monitors: These monitors can track your blood sugar levels and alert you if they get too low.
• Inhaler Trackers: These trackers can help you understand what triggers your asthma attacks.

IoT is making healthcare more personalized and efficient. It's helping people stay healthy and get the care they need.

Conclusion

IoT in healthcare is revolutionizing the industry by improving patient care, reducing costs, and enhancing efficiency. Through connected devices and sensors, IoT enables real-time monitoring, personalized treatment plans, and data-driven decision-making. Moreover, this technology has the potential to transform healthcare delivery, making it more accessible, effective, and patient-centered.
