SYSTEMS AND METHODS FOR DIGITAL PREDICTIVE DISEASE EXACERBATION AND PRE-EMPTIVE TREATMENT
First Claim
1. A system to detect a disease exacerbation, the system comprising:
- a wearable device configured to couple to a patient, the wearable device comprising;
a pulse sensor configured to measure a pulse of the patient by transmitting a light signal toward the patient and receiving a reflection of the light signal transmitted back from the patient;
a breath sensor configured to measure a breath of the patient;
a wireless module configured to communicate data comprising the breath and pulse measurements of the patient detected by the wearable device;
a server configured to receive the data comprising the breath and pulse measurements from the wireless module, the server comprising a prediction engine, wherein the prediction engine is configured to;
generate a digital biomarker as a function of the breath and pulse measurements, the digital biomarker measuring a disease state; and
determine if the digital biomarker crosses a corresponding threshold.

Abstract
The system described herein collects patient data passively and non-passively via onboard and external sensors, and combines the data with past clinical history to generate digital biomarkers. The collected data can also be further combined with other data generating systems to more accurately predict disease exacerbations. The system monitors the digital biomarkers in real-time, and can detect a change in the disease state prior to clinical decompensation and suggest pre-emptive intervention. The system enables a patient to be treated early in the clinical timeline when the disease exacerbation is at the subclinical level rather than waiting until the disease exacerbation reaches the clinical level. Acting when the exacerbation is at the subclinical level enables preemptive treatment rather than reactive treatment, which is often more cost effective while improving clinical outcomes. The system is able to make the predictions by detecting subclinical changes in digital biomarkers that are generated from respiratory, cardiac, patient reported symptoms, user behaviors, and environmental triggers.
