System and method for providing voice feedback for automated remote patient care

Abstract

A system for providing feedback to an individual patient for automated remote patient care is presented. A medical device having a sensor for monitoring physiological measures of an individual patient regularly records a set of measures. A remote client processes voice feedback into a set of quality of life measures relating to patient self-assessment indicators. A database collects the collected measures set, the identified collected device measures set and the quality of life measures set into a patient care record for the individual patient. A server periodically receives the identified collected device measures set and the quality of life measures set from the medical device, and analyzes the identified collected device measures set, the quality of life measures set, and the collected device measures sets in the patient care record relative to other collected device measures sets stored in the database to determine a patient status indicator.

AI Technical Summary

Benefits of technology

The present invention provides a system and method for automated collection, analysis, and feedback of patient information from implantable medical devices. The system receives and stores device measures, such as IPG data, along with other patient records in a database. Voice feedback from the patient is also collected and analyzed. The system can provide normalized quality of life measures based on the collected device measures and spoken patient feedback. This automated system reduces the burden on physicians and trained personnel while enhancing the benefits to patients. The invention also enables simultaneous collection of both physiological measures and quality of life measures. Overall, the invention facilitates holistic remote, automated patient care.

Problems solved by technology

Bradycardia can cause symptoms such as fatigue, dizziness, and fainting.

Tachycardia can result in sudden cardiac death (SCD).

The volume of data retrieved from a single device interrogation “snapshot” can be large and proper interpretation and analysis can require significant physician time and detailed subspecialty knowledge, particularly by cardiologists and cardiac electrophysiologists.

The sequential logging and analysis of regularly scheduled interrogations can create an opportunity for recognizing subtle and incremental changes in patient condition otherwise undetectable by inspection of a single “snapshot.” However, present approaches to data interpretation and understanding and practical limitations on time and physician availability make such analysis impracticable.

However, unlike in a traditional clinical setting, physicians participating in providing remote patient care are not able to interact with their patients in person.

Consequently, quality of life measures, such as how the patient subjectively looks and feels, whether the patient has shortness of breath, can work, can sleep, is depressed, is sexually active, can perform activities of daily life, and so on, cannot be implicitly gathered and evaluated.

These prior art systems lack remote communications facilities and must be operated with the patient present.

These systems present a limited analysis of the collected data based on a single device interrogation and lack the capability to recognize trends in the data spanning multiple episodes over time or relative to a disease specific peer group.

However, the '976 telemetry transceiver, '869 communicator, and '245 programmer / interrogator are limited to facilitating communication and transferal of downloaded patient data and do not include an ability to automatically track, recognize, and analyze trends in the data itself.

Moreover, the '976 telemetry transceiver facilitates patient voice communications through transmission of a digitized audio signal and does not perform voice recognition or other processing to the patient's voice.
