Patients admitted to the General Internal Medicine ward are sick and in need of monitoring that cannot be provided at home or treatments best administered in hospital. Standard care currently includes vital signs measurements and in some cases ECG. Wearable devices that continuous monitor patients could provided added information to improve the care of inpatients. This could include more monitoring and catching deterioration before it happens. Wearables have been shown to be largely accurate for monitoring heart rate, however it is still necessary to determine if they can reliably measure sleep, activity, and other health metrics. For this, study investigators are evaluating the validity of FitBit Sense 2 (or other FitBit devices) for measurement of sleep, activity, heart rate, respiratory rate, and oxygen saturation.
