A Hierarchical Health Decision Support System based on Wearable Medical Sensors and Machine Learning Ensembles
Docket # 17-3310
Researchers at Princeton University in the Department of Electrical Engineering have developed a new hierarchical health decision support system (HDSS) that integrates health data from wearable medical sensors (WMSs) into clinical decision support systems (CDSSs) and can evaluate the health profile for anyone anywhere anytime.
HDSS is the first system that combines WMSs and CDSSs in a carefully structured information framework. The system has a multi-tier structure, starting with a WMS tier, backed by robust machine learning that enables diseases to be tracked individually by a disease diagnosis module. The system utilizes a novel procedure to generate disease diagnosis modules that can monitor various diseases in parallel. The feasibility of HDSS has been demonstrated through six accurate disease diagnosis modules aimed at four disease categories. HDSS can also be applied to other disease categories when datasets for those diseases become available. In addition, disease diagnosis modules for all 69,000 reported human diseases are estimated to need only 62 GB of storage space in the WMSs tier, which is practical even in terms of current technology.
The invention can be used as a pervasive healthcare application on smartphone/personal computer/personal cloud for disease diagnosis and is compatible with commercially available WMSs such as Apple Watch, Microsoft band, Samsung watch, Samsung Band, etc.

Stage of development
We demonstrate the feasibility of the system through six disease modules aimed at four disease categories. We show that the system is scalable using five more disease categories. Just the WMS tier offers impressive diagnostic accuracies for five diseases: arrhythmia (86%), type-2 diabetes (78%), urinary bladder disorder (99%). Renal pelvis nephritis (94%), and hypothyroid (95%).
