The present invention generally relates to a reconfigurable point-of-event diagnostic system, particularly for monitoring patients in real time and pushing event-specific physical and cognitive diagnostic. The invention discusses system and method to monitor patients in real time to determine possible onset of any neurological event based on static risk profile and push an event-specific cognitive and or physical diagnostic.
A neurological disorder causes structural, biochemical or electrical abnormalities in the brain, spinal cord or other nerves can result in a range of symptoms. Examples of symptoms include paralysis, muscle weakness, poor coordination, loss of sensation, seizures, confusion, pain and altered levels of consciousness. There are many recognized neurological disorders, some relatively common, but many rare. They may be assessed by neurological examination, and studied and treated within the specialties of neurology and clinical neuropsychology.
The World Health Organization estimated that neurological disorders and their sequelae (direct consequences) affect as many as one billion people worldwide, and affect people in all countries, irrespective of age, sex, education, religion or income. Interventions for neurological disorders include preventative measures, lifestyle changes, physiotherapy or other therapy, neurorehabilitation, pain management, medication, or operations performed by neurosurgeons.
Despite the availability of highly effective, low cost medication, many patients suffering from various neurological disorders, such as epilepsy, stroke etc., go untreated at the exact time of the occurrence of an episode. In the past, such a diagnosis/treatment has been performed by doctors in hospital settings. It is typically performed using detailed medical examinations. EKG and other medical tests.
Therefore, there is a need of a method and/or system that can monitor patients and detect possible onset of neurological events in patients, even when they are not in a hospital. Additionally, diagnostic tests could be administered to the patient during and, or after the onset of an occurrence of an episodic event for a better assessment of patient. The present invention addresses these issues and provides a better framework for monitoring and administering real-time diagnostic tests thus, reducing deaths and saving and monitoring lives.
In an embodiment of the invention, the reconfigurable point-of-event diagnostic system comprises of a body-worn factor configured for capturing any one of a physical, physiological and, or motion characteristic set of parameters for more advanced analytics than prior art in this field. This invention integrates both physical sensors and biological sensors to join into a new level of analysis and algorithms explained here. The invention is a notable step forward in creating more intelligent and complex analysis of multi-sensor applications to analyze the human body.
More specifically, the present invention relates to a system to monitor a plurality of patients to detect possible onset of a neurological condition and/or other similar medical conditions. In an embodiment of the present invention the reconfigurable point-of-event diagnostic includes capturing at least the first set of physiological, physical and, or motion parameters of a patient and based on at least the first set of parameters, compare to a static risk profile, detect a threshold-grade deviation therefrom to deduce a neurological event type. Further yet, in an embodiment of the invention based on the neurological event type, push at least one of an event-specific cognitive and, or physical diagnostic request further validating the neurological event by the validation module based on the results of the diagnostic. Additionally, in an embodiment of the invention, the information of the validated neurological event is pushed to any one of a designated recipient.

Going further, sleep related characteristics of the patient are indicative of at least one of the group comprising sleep time, number of times awake, duration of sound sleep, duration of light sleep and awake time. The physiological characteristics of the patient are one or more of group comprising heart rate, pulse rate, respiratory rate and body temperature. Additionally, in an embodiment a set of parameters corresponding to the physical characteristics is based on at least one of, age, gender, race, medical history, heart rate, medication history, blood pressure, sweat, duration, number of episodes and history of disease, family history, fatigue, walking/running/movement related impairment, bladder dysfunction, vision and speech impairments, food habits, smoking, alcohol and drug intake.

Once the device input 200—however disparate—is aggregated, reconfigurable point-of-event diagnostic system captures at least one set of the physiological, physical and or motion parameters of a patient, it compares it to a static risk profile 208. If a discrepancy is above a pre-defined threshold and or if the system detects a threshold-grade deviation 209, then the system, assesses 202 the potential threat, alerts the patient and or designated recipient and pushes an event-specific physical 204 and or cognitive 205 diagnostic to the patient. Based on the response to at least one physical and or diagnostic, the validation module validates the neurological event and alerts the designated recipient. In another embodiment, in addition to alerting the patient, the reconfigurable point-of-event system may be configured to provide at least one automated response to the assessed and alerted patient. Further yet, the patient alert may be at least one of, text, email, vibration with or without audible notification, visual display, and, or a color-coded or blinking notification.
In a preferred embodiment, device data input 200 may encompass the sensor-captured raw data input or transduced and processed data input from the body worn device that is the subject of the supra device and method claims. Device input 200 may also encompass the sensor-captured raw data input or transduced and processed data input from any other device associated with the patient/user. Examples may be devices worn, mobile devices, and, or fixed-access devices, such as Internet-of-Things devices (e.g. smart thermostat, home automation consoles, etc.). The plurality of device inputs provides additional input for aggregation and behavior profiling, thus layering the behavior profile with additional context for generating a higher fidelity of predictive analytics. Alternatively, the data input 200 may be from at least two disparate devices—capturing and processing non-overlapping motion or behavior parameters. In yet other embodiments, the data input 200 may be from at least two disparate devices—capturing and processing overlapping motion or behavior parameters. For instance, the reconfigurable system may employ a 6-axis accelerometer data input 200 of the body worn device and the 3-axis accelerometer data input 200 of an additionally worn fitness tracker and stack these motion metrics to generate a composite gait profile. Conversely, the data input 200 may be from at least two disparate devices capturing non-overlapping metrics, such as accelerometer data from the body worn device and gyroscopic data from a fitness tracker to inform the composite gait profile.
In an alternative embodiment of the invention, these multiple and heterogenous data inputs 200 may converge in an integration layer (not shown). The integration layer may further manage the data packets—of varying format—and collate into discrete bundles of packets/formats. In other embodiments, the integration layer may serve as a data format converter, converting the plurality of data formats—from disparate devices—into a universally recognized format. In yet other embodiments, the plurality of data inputs 200 and formats converge into the interaction policy layer for any one of collating the disparate data formats from a multitude of devices; and, or, converting the disparate data formats into a universally recognized data format; and aggregating the bundled and, or converted data inputs for configuring a composite static profile 208.
Devices—however disparate—including the body worn device, can communicate with integration layer wirelessly via Bluetooth—or any other short-range communication protocol—interfacing with any one of a mobile phone, Wi-Fi router and Wide Area Network access. The care-flow controller aggregates a first set of parameters from the body worn device and a second set of parameters from at least one of, a mobile communication device, wearable device, smartphone, tablet, personal digital assistant (PDA) and Internet of Things device.
The static risk profile 208 or any other reference profile (not shown), take into account complete device behavior. Device behavior includes not only data output informed by patient/user behavior, but also data output informed by network and device technical characteristics. Such technical characteristics may consider network traffic, bandwidth, network bottlenecks, network malfunctioning, device malfunctioning, sensor data acquisition fidelity, signal transduction, latency, patient feedback, etc. By taking in such device and network technical characteristics, the system may be able to make a secondary assessment of a discrepancy threshold and rule out device or network malfunctioning—verifying that the threshold discrepancy is due to a patient threat. In some embodiments, the event-specific physical and or cognitive diagnostic is pushed or the alert of a patient threat and, or automated response is triggered only after the device and, or network anomaly is ruled out after the discrepancy threshold is reached.

The static risk factor value is calculated based on one or more of the static parameters described above. Typically, the static risk factor value is in the range 0-100%, wherein 0% signifies no risk and 100% signifies a very high risk of having a stroke. In another example, static risk factor values in the range of 90-100 correspond to an “extremely high-risk profile” and color coded in red, whereas static risk factor values in the range of 70-90 correspond to a “high risk profile” and color coded in orange. Further, static risk factor values in the range of 50-70 correspond to a “moderate risk profile” and color coded in yellow whereas static risk factor values in the range of 25-50 correspond to a “low risk profile” and color coded in blue. Going further, static risk factor values in the range of 0-25 correspond to “no risk profile” and color coded in green.

The plurality of questions and/or instructions are used to check the patient's response to at least one of a visual or color appearance, audio or sound and a buzzer or vibration. Further, characteristics of the patient such as slurring of speech, vision impairment and/or fine motor skills may also be checked for the validation of the neurological event. The patient may also be asked to repeat actions, sounds and movements, and answer memory based questions. In an embodiment, the caregiver is also instructed to check a physical characteristic of the patient. Examples of the physical characteristic include, but are not limited to whether the patient is able to raise his arms, facial drooping and paralysis. Typically, the diagnostic presented to the patient and the instructions presented to the caregiver are in accordance with the Face, Arm, Speech, Time (F.A.S.T.) or similar protocol or tests.
