Connected tools in healthcare

Connected tools, also known as the Internet of Things (IoT), have been present in our hospitals for many years. In our day-to-day lives, they are becoming more and more common and an integral part of many areas of our lives, including our health, without us even being fully aware of it. Just think how many people around you are now wearing an activity bracelet or a connected watch on their wrist!

Other examples could be blood pressure and glucose monitors, which often connect with apps we can install on our mobile devices, offering additional, and very useful, functionalities for monitoring chronic diseases.

As for connected tools offering more futuristic functionalities, they are on the increase, and it's worth taking a closer look at them, to discover these unsuspected new uses, and to reflect on the future of these connected objects.

How are connected tools useful in healthcare?

There are a number of ways in which these tools are particularly useful in healthcare. For example, they can facilitate:

  • Follow-up and monitoring of a person's state of health, at home, by a caregiver or by a remote treatment team. This team can then monitor a large number of patients, and issue alerts in the event of data deviating from the target range;

  • Patient management of chronic diseases, facilitated by apps that not only automatically synchronize and store device data, but also analyze it and offer trends and feedback to the user, supporting awareness or offering personalized advice.

  • Direct follow-up with the healthcare provider, via telemedicine, which can, among other things, help improve care accessibility;

  • Patient autonomy, enabling them to better understand and manage their health at home, and in a much more autonomous way;

  • Health research, through the use of data generated by a large number of users. This can help to understand day-to-day illnesses, their evolution, the user habits and their impact, and much more information that can be used to develop the therapies of the future.

Innovative connected tools

Here are a few concrete examples of connected devices that are interesting, surprising or paving the way for the tools of the future.

It's important to point out that many of these new devices have not been the subject of studies proving their safety or efficacy, let alone been approved as medical devices. So, if you're interested in one personally, or in making a recommendation, you need to be cautious and well-informed. In particular, the issue of data confidentiality is often raised when it comes to these connected health devices.

Note, however, that when a tool is identified as being approved as a medical device, it is taken for granted that studies have been carried out and that the results were conclusive, even if this is not explicitly mentioned below.

A brain stimulation device for the treatment of depression and anxiety disorders

Via a headset called Flow, this system offers an additional alternative in the treatment of depression and anxiety disorders. Flow delivers transcranial direct current stimulation (tDCS), a therapy that has long been used clinically to treat depression, but this time, at home.

The app, required to use the headset, offers a therapy program covering a range of topics from behavioral therapy to lifestyle habits such as meditation, sleep, diet and exercise. The app also invite users to take a depression severity test (MADRS-s) at intervals, with the aim of tracking the changes, and to increase awareness of state changes over time.

This device is particularly interesting because it has been the subject of 2 clinical studies, one of which concludes that "Stimulation was well-tolerated and accepted, with mild tingling sensation and scalp discomfort being the most common side effects. [It] highlights the applicability, acceptability, and promising results when combining home-based tDCS with psychotherapy and pharmacotherapy to manage depression and anxiety symptoms in clinical practice."

For pelvic floor health

Classified as a medical device within the European Union, MyPeriTens is a wireless, app-connected tool that uses transcutaneous electrical nerve stimulation (TENS) to relieve pain, and electrical muscle stimulation (EMS) to strengthen pelvic floor muscles.

MyPeriTens also includes exercises based on Kegel's method, and could therefore help in the treatment of certain forms of urinary incontinence.

For asthma and COPD (chronic obstructive pulmonary disease)

Propeller is a connected healthcare tool consisting of a sensor that attaches to an inhaler (sometimes called a pump) for the treatment of asthma or COPD, and communicates with the app of the same name. The latter collects data on medication use and creates a personalized profile to promote compliance with the treatment plan.

Other features include reminders to take medication, monthly reports on inhaler use, a daily overview of air quality and weather forecasts, tracking of rescue medication use to identify triggers, and a function to locate misplaced inhalers.

The system has been the subject of several acceptability and clinical value studies. One such study demonstrated a significant reduction in rescue medication use and an improvement in asthma control scores “among adults initially lacking asthma control” (2).

A new level of guidance during meditation

Muse is a headband that acts as a real-time meditation coach. EEG sensors detect when the mind wanders, and the app then provides an audible cue to bring the user back to the present moment. Guided activity thus helps to ignore distractions and achieve higher levels of concentration and attention during meditation.

The acceptability and effectiveness of Muse has been the subject of a small, published pilot project, which demonstrated health benefits, safety and acceptability of the device, and the absence of reported side effects (3).

The present and future of connected healthcare tools

As you can see, connected healthcare devices now exist in many areas of healthcare. We've named just a few, but could have added to this list: cyberpills, insulin pumps that calculate and inject the required insulin dose, connected beds, smart pillboxes, smart patches, and many more!

Although the efficacy and safety of each of these devices is not always proven, some are approved by major regulatory agencies in North America and the European Union. In all cases, it would be prudent to speak with a healthcare professional before purchasing or using any of these devices.

The future holds other connected tools that could modify or add to the treatment of several diseases for which current treatments are unsatisfactory, such as Parkinson's Disease and Alzheimer's Dementia.

There's even talk of implanted microchips that could one day be used to monitor our health parameters, not to mention nanobots! So, when it comes to connected tools, the future will continue to surprise and impress us!
