Understanding if your sleep tracker is clinical grade

Nearly 100 million Americans have some sort of sleep disorder, be it insomnia, restless legs syndrome, or sleep apnea.

In recent years, the fitness tracker industry took note of the increased attention on sleep and added basic sleep-related insights to their offerings. One study showed that 1 in 5 fitness trackers are purchased primarily for sleep tracking.

Yet a nagging question remains with many of these consumer products: what is the veracity of their claims, and what clinical standards—if any—have they been held up against? There should be a clear way to differentiate clinical grade products from basic consumer gadgets that are not held to the same high standards.

In developing the Beddr SleepTuner, here are the six factors that we at Beddr believe should define a clinical grade product.

1. Extensive Testing

The way we see it, clinical grade products must be extensively tested on users and compared to existing best-in-class products to validate their accuracy and claims. Whenever possible, clinical grade devices should be compared against existing FDA-cleared products that have conducted extensive scientific testing.

It’s important for clinical grade products to be tested to ensure that they do not cause adverse effects to the person who uses them. In addition, the product must endure a battery of reliability tests to ensure that it will work within the specific conditions for which  it was designed.

2. Transparent specifications and performance

A clinical grade product must publish detailed specifications and performance criteria including accuracy, intended use, and more. Non-clinical grade products are under no obligation to provide any of this information, and most don’t.

For example, have you ever wondered how accurate the heart rate monitor is on a Fitbit or Apple Watch? If you have, you’re certainly not alone. Everyone who buys a clinical grade device—like the Beddr SleepTuner—will see the accuracy stated in the user manual.

3. Meeting benchmarked accuracy

Another hallmark of a clinical grade product is meeting established standards for accuracy.  Standards are developed to codify what is the minimal acceptable performance.  Consumers can trust that clinical grade products have met or exceeded standards.  

4. Evidence-based

In order for a company to call their device a clinical grade product, their claims should be based on proven science. This typically consists of peer-reviewed research or methodologies that are the accepted standard by the experts within a particular field. In the field of sleep medicine, for example, products are studied both in and out of a lab setting, and compared to existing best practices.Beddr gathers data that is well-understood by sleep physicians and is used daily in their practices.

5. Transparent methodology

Whenever possible, Beddr publishes the methodology we use to calculate sleep metrics. Of course, some information is proprietary, but there is still a way to inform the user how data is arrived at without giving away company secrets.

Transparency around how data is gathered, analyzed, and how it compares to clinical tools is key, and ensuring that the device is understood and respected by experts in the space—usually physicians and scientists—lends further credibility to products deserving of a clinical grade label.

6. Controlled Product Development and Manufacturing Process

A clinical grade product is developed within a comprehensive quality system that documents the design, material, and processes that are used to create the product.

Similar to medical grade products, clinical grade products should be made in specially certified manufacturing facilities under controlled conditions. For example, the Beddr SleepTuner is manufactured under a comprehensive quality system in an ISO 13845 facility.

A great amount of care should be taken when journeying through new territory in health tech, and designing something that can have an impact on someone’s sleep health is an endeavor we at Beddr take very seriously.
