Location Tags in Smart Healthcare: What, How, and Why
MinewMinew
The COVID-19 pandemic shifted the focus of healthcare IoT toward telehealth. It’s true that connected devices are creating powerful new ways to care for patients remotely; wearable health monitors are just one high-profile example. Â
But IoT isn’t just for distance medicine. In a post-lockdown world, healthcare IoT is also streamlining operations for hospitals, clinics, and other in-person care facilities. One of the most effective ways to reap the benefits of smart healthcare—including lower costs, better patient outcomes, and less stress on staff—is to deploy a fleet of IoT location tags.
These tags are available as wearables, supporting a variety of use cases for patient care and staff support. Or you can attach tags to medical equipment to create an automated asset tracking system.Â
Location tags offer a cost-effective way to move toward smart healthcare modalities. They don’t require you to redesign your whole IT or OT tech stacks. In short, location tags offer a great entry point for healthcare IoT. Most importantly, this IoT technology can provide remarkable benefits for patients and the providers that care for them.Â
In this article, we’ll answer three key questions:Â
Here’s your introduction to smart healthcare, courtesy of IoT location tags and the systems they support. Â
A location tag or location wearable is a radio-enabled device that transmits its location in space to a wireless gateway. (Gateways, in turn, can relay data to cloud platforms and, eventually, user interfaces.)Â
Many location tags include additional functionality: accelerometers track movements, alert buttons send notifications, and sensors track conditions like temperature or humidity. For this introduction, however, we’ll stick to the basic feature of a location tag, which is sending real-time data on where the tag is located.Â
Location tags and their gateways may use any number of wireless technologies to share data: WiFi, cellular, LPWAN, etc. For most healthcare facilities, however, Bluetooth Low Energy provides the ideal form of connectivity for location tags.Â
This connectivity technology was designed to preserve battery life, reducing the need for charging or swapping batteries to an absolute minimum. Indoor tracking systems that use Bluetooth Low Energy are also remarkably accurate, pinpointing tags within a meter or two. These systems just require a fleet of location tags (and/or wearables) and gateways to deploy.Â
Regardless of the connectivity that connects them, healthcare location tags provide real-time visibility into asset or staff locations. How exactly does that help? Here are just a few common use cases for location tags in the healthcare industry.Â
Location tracking IoT can improve operation for any healthcare facility, whether you operate a hospital, an assisted living center, or a specialist medical office. Use a fleet of location tags for the following healthcare tasks:Â Â Â Â
Of course, these examples are far from comprehensive—and when you add condition monitoring and response equipment to location tracking devices, the possibilities of smart healthcare expand significantly.Â
Next, we’ll look at some of the clear advantages location tags bring to healthcare facilities.   Â
Even putting aside monitoring and notification features, location tags help healthcare providers—and their patients—in a variety of ways. Here are just a few of the benefits:Â
Studies support the use of IoT in healthcare to achieve cost savings, better treatment outcomes, fewer errors, and more satisfied patients. That makes perfect sense once you know what location tags are; how they help; and why medical providers need them. In short, location tags offer a low-barrier way to start delivering these benefits to the patients you serve today.Â
