Noninvasive Hypoglycemia Detection in People With Diabetes Using Smartwatch Data

Abstract: OBJECTIVE To develop a noninvasive hypoglycemia detection approach using smartwatch data. RESEARCH DESIGN AND METHODS We prospectively collected data from two wrist-worn wearables (Garmin vivoactive 4S, Empatica E4) and continuous glucose monitoring values in adults with diabetes on insulin treatment. Using these data, we developed a machine learning (ML) approach to detect hypoglycemia (<3.9 mmol/L) noninvasively in u… Show more

“…Previously, we have shown the general concept of hypoglycaemia detection using smartwatch data 4 . The present analysis suggests that this concept extends to detecting pronounced hypoglycaemia even when people are involved in tasks related to cognitive and psychomotor stress, such as driving.…”

“…While electrodermal activity, heart rate variability and accelerometer features constitute relevant features for hypoglycaemia detection, 2,4 the accuracy of ML decision-making across different levels of hypoglycaemia is unknown. Electrodermal activity proved to be a decisive feature modality for detecting pronounced hypoglycaemia, but appeared to be less informative in detecting mild hypoglycaemia.…”

“…The widespread use of such technology accompanied by automated and standardized reports including indices of interest could lead to a better understanding of several mechanisms with great clinical potential. Wearable devices allowing non-invasive glucose monitoring or cuffless devices performing frequent BP measurements could provide detailed assessments of glucose and BP profiles including GV and BPV [ 41 , 42 , 43 ]; however, such devices have not been validated with respect to their accuracy according to established protocols and, most importantly, in terms of their clinical utility and intended use [ 41 ]. The association between GV and BPV could highlight the importance of several common underlying mechanisms.…”

“…One approach to overcome this burden might be the use of data obtained from non-invasive measurements of physiological parameters by wearables which have been shown to respond to upon changes in the blood glucose level. Initial proof-of-concept studies show that hypoglycemic events can be detected by heart rate variability and electrodermal activity using wearables in prediabetes and diabetes [17][18][19] .…”
