Wearable devices are integrating more advanced health sensors and biomarker tracking capabilities, providing deeper insights into users' wellbeing. However, Dr. Brandon Stucky of AdventHealth warns these gadgets are not a substitute for clinical evaluation and should be used as empowerment tools for lifestyle changes, not diagnostic devices.

Why it matters

As wearable tech becomes more sophisticated, it's important for consumers to understand the strengths and limitations of these devices in order to use the data effectively to improve their health, without over-relying on the technology for medical diagnoses.

The details

Wearables now offer clinical-grade sensors for tracking ECG, blood oxygen, blood pressure, heart rate variability and other physiological biomarkers. They are also enabling non-invasive continuous monitoring of metabolic markers like glucose levels. However, Dr. Stucky cautions these devices can have variable accuracy, especially for detecting irregular heart rhythms, and should be used to provide additional health context to share with medical providers, not to make diagnoses on their own.

What they’re saying

“Irregular heart rhythms are a good example. These devices have variable accuracy for predicting them; I've had patients present with arrythmia notifications that have been a false alarm and ones that have been accurate.”

— Brandon Stucky, MD, Family Medicine Physician (AdventHealth)

“I view the technology as an empowerment tool versus a diagnostic tool. They're really helpful with lifestyle modification and self-monitoring, but they're definitely not a substitute for clinical evaluation.”

What’s next

Patients should continue to share data from their wearable devices with their healthcare providers to help inform their overall health assessments and treatment plans.

The takeaway

Wearable health tech is becoming more advanced, but consumers should use these devices as tools to support lifestyle changes and provide additional context to their doctors, not as replacements for professional medical care and diagnosis.
