How Can IoT be Used to Improve the Quality of Healthcare?

Connected Devices Automatically Track Patients

One of the main problems most healthcare professionals struggle with is the lack of information regarding a patient’s health and treatment outcomes once the patient leaves the hospital. This causes another issue for patients – the need to come in for several follow-up visits just to report any new feelings, issues, side effects, or improvements to redirect or confirm a specific treatment plan.

Wearable devices resolve both these issues by making treatment much more manageable for both patients and doctors.

For instance, some wearable devices are used to measure patient vitals, such as heart rate, blood pressure, temperature, breathing, and more. IoT devices in medical field then transfer data to nurses or healthcare professionals. In case the patient has some health problems, the device will send an alert to the person monitoring the device, preventing lethality and reducing unnecessary ER visits.

IoT Improves and Eases Patient Data Collection and Records

Wearable connected devices offer endless opportunities for collecting patient data. Let’s take as an example a patient in a smart bed — medical staff will be able to collect a large volume of useful data recorded automatically.

Electronic records collected from IoT wearable medical devices also help nurses since they reduce the need for chasing down information on each patient. The data can later be safely stored in their electronic health record, making treatment and diagnosis easier.

Patient Health Assessments

Besides changes in patients from doctors, individuals will also be able to improve their health with accurate assessments. Some medical apps have already given patients control over their health.

There are sleep applications allowing users to monitor sleep health, maintain a circadian rhythm and monitor sleep cycles. Fitness applications connected with wearables allow users to stay in shape. Calorie intake and count software provides a tailored nutrition plan so users know what to eat and what to avoid based on their preferences and health needs.

Vaccine Delivery Optimization

IoT in the healthcare domain is also used for vaccine transport and storage. There are many vaccines that have to remain at extreme temperatures so they don’t expire. IoT sensors are an effective solution that maintains these low temperatures and informs staff in case of an issue.

In fact, there are IoT devices in vaccine shipment units that can automatically adjust the needed temperature based on real-time data, just like smart thermostats some have at home. The same sensors alter a proper employee if something happens that jeopardizes the cooling system’s integrity.

Benefits of IoT for Connected Medical Devices

Enhanced Diagnostics and Treatment

A good example of how IoT in healthcare improves diagnostics and treatment is capsule endoscopy. In contrast to uncomfortable and scary endoscopy, patients just need to swallow a pill with an integrated mini-camera taking pictures of the digestive tract.

Just like with endoscopy, pictures taken with this small capsule allow doctors to analyze the situation and make an accurate diagnosis. Healthcare professionals can also use Machine Learning here to automate picture processing to treat patients more effectively.

Customer Satisfaction

Alongside using medical devices, IoT improves customer satisfaction. That is because they are more involved in the process and have greater access to all needed information than ever before.

The connected medical infrastructure allows patients to communicate easily with clinics while also allowing doctors to monitor their health remotely and in real time. This way, patients feel more informed, reduce unnecessary visits and questions and improve overall satisfaction.

Remote Monitoring

Patients with specific treatment plans or chronic conditions benefit from remote monitoring. For instance, wearable devices monitoring glucose levels in the blood have changed the way patients with diabetes live, improving their health and reducing risks. These devices send real-time information to doctors.

Staff Monitoring and Compliance with Requirements

Hospitals are pretty busy places at any time of the day, meaning managers can’t monitor everything and everyone. IoT devices and connected software automate staff monitoring and compliance-monitoring processes. This process saves both money the clinic otherwise would spend on potential lawsuits and reduces compliance-related costs.

Open More Business Opportunities

IoT architecture opens more business opportunities. Collected data is aggregated and located in the cloud, allowing Machine Learning algorithms to examine it and provide valuable insights.

Preventive Care

Preventing care must be the key focus since it helps patients avoid severe consequences and new diseases. IoT in medical devices offers highly accurate data regarding each patient’s case, revitalizing the healthcare sector and helping patients live healthy lives by preventing severe diseases.

Overall Costs Reduction

Insurance companies increasingly rely on performance-based reimbursement of healthcare companies as healthcare costs rise. As a result, doctors have to constantly prove they can help their patients to get compensation for their care.

Clinics can reduce overall costs by furnishing IoT wearable medical devices and discharging patients from clinics much earlier. This will help doctors to monitor patients’ health and results from treatments.

IoT for Medical Devices: Adoption Challenges

1 Data Security and Privacy

Protecting patient data from cyber threats and ensuring patient privacy is a key concern in IoT healthcare devices. These devices are interconnected in nature, so they may increase the risk of unauthorized access and data breaches. When relying on IoT technology, clinics need to ensure proper installation of hardware and software, monitor activity, and timely conduct software updates.
2 Connectivity

Achieving tamperproof, seamless communication and interoperability among IoT based medical devices from different providers is a challenge. For example, ONC has already implemented steps to ensure the achievement of smooth connectivity and interoperability and make sure government incentives are in place to allow healthcare organizations to adopt EHRs. Otherwise, they will write fines to organizations that fail to implement IoT technology.
3 Reliability and Accuracy

Maintaining the accuracy and reliability of IoT devices in the medical sphere is critical for making data-driven clinical decisions. Factors like data transmission errors, device malfunction, and sensor calibration may impact the work of these devices. It is crucial to ensure they function the way they are supposed to, check battery life, and follow the manufacturer’s offers regarding system updates.
4 Cost

The adoption of new technologies always involves increasing costs. In the case of IoT medical devices, the process also involves the acquisition of devices, proper infrastructure development, and system integration. Ongoing expenses like staff training, data protection, updates, and system maintenance also affect the overall cost in the long run. Clinics should consider IoT medical devices implementation case by case, leaning on the predicted benefits and potential return on investment.
