Applications of IoT in healthcare: key areas

Remote patient monitoring

Remote patient monitoring (RPM) devices can continuously measure health parameters and synchronize the data with clinical systems. This way, clinicians can view the history and real-time data about a patient's health conditions, carry out deeper analysis, and receive alerts of dangers to a patient's health.

Telehealth

IoT technology enables telemedicine practitioners to conduct remote patient examinations and instruct patients on how to conduct certain treatment procedures during virtual neurology visits and telepediatric or telepsychiatry sessions.

Efficient diagnostic & treatment

Using smart medical equipment, doctors get results of various examinations like blood tests, MRIs and CT scans, and X-rays much faster. If the devices are connected to analytical systems powered by artificial intelligence, then doctors can receive intelligent insights based on this data.

Additionally, IoT technology makes diagnostic and treatment procedures possible to perform during virtual neurology visits, telepediatric or telepsychiatry sessions.

Patient self-care

Patients can keep track of their physical and mental health, sleep, and nutrition, get notified of abnormal health indicators and learn to lead healthier lives or manage their condition more effectively with the help of wearable medical devices connected to health and wellness apps on their smartphones.

Smart hospitals enablement

Hospital IoT enables automatic environmental tracking and control in the facilities: air and water quality checks, hygiene monitoring, and temperature balance. It also simplifies inventory management in the hospital and notifies personnel in case of emergencies. Smart hospital devices ensure more responsive care, allowing patients to regulate their medication or notify personnel if needed.

Medication management

Equipment like medication pumps, adverse reaction trackers and drug interaction trackers can ensure timely, safe and accurate administration of medication to patients. Meanwhile, pharmacies can employ smart weights, storage monitoring devices, and discharge and labeling machines to support precise medication management as well as proper storage and disposal.

How IoT in healthcare works

Some people imagine IoT devices as intelligent robots because the system appears to be highly automated. In fact, any object (mechanical or digital) that has a unique identifier (UID) and the ability to collect and transfer data over a network without human intervention can be a part of IoT. Such devices might also analyze the acquired data prior to sharing it or act upon the information they get from one another.

IoT can make use of multiple technologies and protocols to exchange data, but the most widely employed are radio-frequency identification (RFID), near-field communication (NFC), low-energy Bluetooth, low-energy wireless, radio protocols like ZigBee, Z-Wave and Thread, LTE Advanced, and WiFi-Direct.

These technologies enable low energy use that prolongs the lifetime of devices, supports secure connection, and enables various coverage ranges.

Top 10 use cases of IoT in healthcare

New use cases for healthcare IoT appear every day. Below, we list some of the most popular ones.

Remote patient monitoring

Using IoT devices to monitor a patient's condition in the ward or at home is the most common application of the technology. IoT-powered equipment that automatically collects metrics like heart rate, blood pressure, temperature, or glucose levels in the blood spares patients from traveling to their provider for health checks. Activity trackers also can shed light on a patient's lifestyle and habits, while mood management tools can facilitate more accurate mental assessment.

Medical alert systems

These are a subset of RPM devices that alert family members, caregivers, or medical personnel that their help is needed. Worn mostly by people who don’t need constant care, but are at risk for accidents: elderly who can fall and easily break a hip, pregnant women, people experiencing sudden bouts of vertigo or migraines or patients with impaired motor function. If an accident happens, the device will send an emergency message to a designated number.

In-hospital patient monitoring & diagnostics

There are also medical IoT devices that monitor all of a patient’s vitals in a hospital setting when a patient's condition requires constant observation and swiftly notify personnel about any dangerous changes. For example, heart monitors can alert healthcare professionals when patients are experiencing arrhythmia, palpitations, tachycardia, or other abnormalities of the heart rhythm.

Ingestible sensors

Healthcare providers use pill-shaped diagnostic devices for gastrointestinal problems detection (colon cancer, irritable bowel syndrome, duodenal ulcer, etc.), treatment monitoring, and preparation for surgery. When ingested, the sensor can send different kinds of medical data to a connected app, like images of the digestive system, levels of various substances inside it, or even the content of the gut’s microbiome.

Medication dispensing

Patients can get implantable drug delivery devices, like insulin or buprenorphine pumps or histrelin and other hormonal implants, that dispense accurate doses of medication throughout the day. Such devices release therapeutic agents to the area where it is most needed. They can also be connected to health monitoring devices that signal exactly how much drug should be injected depending on the patient’s health metrics.

Asthma management

Connected smart inhalers can analyze environmental factors, patient’s health metrics and inhaler use rate to warn patients of an upcoming asthma attack via notifications on their device of choice. Such inhalers can also remind patients to adhere to their treatment plans.

Medicinal footwear & clothing

Smart garments that automatically adjust the pressure on different body regions or their moisture levels and temperature can be used for diabetic foot ulcer prevention, lymphedema or deep vein thrombosis (DVT) treatment, wound care and rehabilitation, and alleviation of various motor dysfunctions.

Environment monitoring

Hospitals can also make use of wireless sensors that react to the slightest changes in temperature, humidity, air quality and levels of contamination in labs and hospitals. These devices can ensure that medications, biological materials, and medical equipment are in proper condition and the facilities are safe for patients and personnel.

Item inventory tracking

Hospitals can tag high-value hospital equipment, like wheelchairs, infusion/dialysis stations, and smart beds, or equipment that should be located at a particular place, like defibrillators, with Bluetooth-based iBeacons, RFID, or QR tags. This can make asset tracking easier and prevent lengthy searches for misplaced items.

Predictive maintenance

There are two ways predictive maintenance can be carried out in an IoT-enabled hospital. First, smart devices can self-check regularly and notify personnel about their working condition, and second, intelligent sensors can check traditional hospital hardware and alert the maintenance crew if a failure is predicted.

Patient flow tracking & management

Smart devices with face recognition installed in hallways and wards of modern smart hospitals can monitor patients from admission to discharge. This data can be fed into the analytics system to detect underutilized areas and locations that might become overcrowded and improve patient flow management.

Overcoming common challenges of IoT in healthcare

Despite its benefits, IoT is still associated with data breaches, the risk of a crucial device failure, and other issues that put off healthcare providers and make them second-guess the decision to adopt IoT. However, IoT software developers and device manufacturers are successfully solving the existing problems and trying to prevent any upcoming ones.

Challenge

Solution

According to the Cynerio report, more than half of the IoT healthcare devices pose risks for hospitals that use them.

The same report points out that effective healthcare IoT segmentation (dividing the large network into smaller, more manageable sections) helps mitigate the most critical smart device risks.

There are many different communication protocols, which makes data collection much more difficult and slows down the processes.

Though device manufacturers have not reached an agreement on a single standard for communication protocols, they are working on standardization of the connection between IoT devices for smoother data transfer.

Huge volumes of data take up a lot of space and cause fatigue in professionals working with it.

Data management, analytical and charting tools and cloud-based storage make it easier to manage high volumes of data and transform it into comprehensible insights.

IoT is vulnerable to such unpredictable emergency events as energy disruptions and severe weather conditions.

Most healthcare facilities have already realized the importance of proper hardware and software backup. Most have already started to develop a disaster recovery strategy and adopt recovery tools.

Healthcare providers can struggle with expanding their IoT networks with new devices.

Healthcare organizations should make their IoT network future-proof by design. The best and most accessible way to do so is by applying cloud services for device management and data storage to create scalable architectures that can efficiently accommodate a growing number of devices.
