Abstract

A system and method for analyzing normalized patient voice feedback in an automated collection and analysis patient care system is described. Device measures providing physiological measures collected by an implantable medical device on a substantially continuous basis are received for storage into a patient care record. Voice feedback spoken by an individual patient substantially contemporaneous to the collection of at least one set of the device measures is received. The voice feedback is processed into normalized quality of life measures for storage into the patient care record. The physiological measures and the quality of life measures stored in the patient care record are analyzed relative to at least one of other physiological measures and other quality of life measures to determine a patient status indicator.

Claims

1. A system for analyzing normalized patient voice feedback in an automated collection and analysis patient care system, comprising:

a database module receiving device measures providing physiological measures collected by an implantable medical device on a substantially continuous basis for storage into a patient care record and receiving voice feedback spoken by an individual patient substantially contemporaneous to the collection of at least one set of the device measures;

a feedback module processing the voice feedback into normalized quality of life measures for storage into the patient care record; and

an analysis module analyzing the physiological measures and the quality of life measures stored in the patient care record relative to at least one of other physiological measures and other quality of life measures to determine a patient status indicator.

2. A system according to

claim 1

, further comprising:

the analysis module comparing the physiological measures and quality of life measures stored in the patient care record to at least one of physiological measures and quality of life measures stored in patient care records for the individual patient, a patient peer group, and a patient population.

3. A system according to

claim 1

, wherein the physiological measures comprise at least one of a collected physiological measure or a derived physiological measure.

4. A system according to

claim 1

, further comprising:

the feedback module generating automated feedback from the patient status indicator.

5. A system according to

claim 4

, further comprising:

the feedback module providing tiered automated feedback comprising;

at a first level of feedback, communicating an interpretation of the patient status indicator;

at a second level of feedback, communicating a notification of potential medical concern based on the patient status indicator;

at a third level of feedback, communicating a notification of potential medical concern based on the patient status indicator to medical personnel; and

at a fourth level of feedback, communicating a set of reprogramming instructions based on the patient status indicator to the implantable medical device.

6. A system according to

claim 4

, wherein the automated feedback comprises at least one of the group consisting of a peer group status indicator, a historical status indicator, a trend indicator, a medicinal efficacy indicator, and a wellness indicator.

7. A system according to

claim 1

, further comprising:

the feedback module requesting the spoken voice feedback through predetermined prompts, each such prompt being associated with a quality of life measure and parsing the spoken voice feedback in accordance with a voice grammar and speech vocabulary.

8. A method for analyzing normalized patient voice feedback in an automated collection and analysis patient care system, comprising:

receiving device measures providing physiological measures collected by an implantable medical device on a substantially continuous basis for storage into a patient care record;

receiving voice feedback spoken by an individual patient substantially contemporaneous to the collection of at least one set of the device measures;

processing the voice feedback into normalized quality of life measures for storage into the patient care record; and

analyzing the physiological measures and the quality of life measures stored in the patient care record relative to at least one of other physiological measures and other quality of life measures to determine a patient status indicator.

9. A method according to

claim 8

, further comprising:

comparing the physiological measures and quality of life measures stored in the patient care record to at least one of physiological measures and quality of life measures stored in patient care records for the individual patient, a patient peer group, and a patient population.

10. A method according to

claim 8

, wherein the physiological measures comprise at least one of a collected physiological measure or a derived physiological measure.

11. A method according to

claim 8

, further comprising:

at a second level of feedback, communicating a notification of potential medical concern based on the patient status indicator;

at a third level of feedback, communicating a notification of potential medical concern based on the patient status indicator to medical personnel; and

at a fourth level of feedback, communicating a set of reprogramming instructions based on the patient status indicator to the implantable medical device.

13. A method according to

claim 11

, wherein the automated feedback comprises at least one of the group consisting of a peer group status indicator, a historical status indicator, a trend indicator, a medicinal efficacy indicator, and a wellness indicator.

14. A method according to

claim 8

, further comprising:

requesting the spoken voice feedback through pre-determined prompts, each such prompt being associated with a quality of life measure; and

parsing the spoken voice feedback in accordance with a voice grammar and speech vocabulary.

15. A computer-readable storage medium holding code for analyzing normalized patient voice feedback in an automated collection and analysis patient care system, comprising:

receiving device measures providing physiological measures collected by an implantable medical device on a substantially continuous basis for storage into a patient care record;

receiving voice feedback spoken by an individual patient substantially contemporaneous to the collection of at least one set of the device measures;

processing the voice feedback into normalized quality of life measures for storage into the patient care record; and

analyzing the physiological measures and the quality of life measures stored in the patient care record relative to at least one of other physiological measures and other quality of life measures to determine a patient status indicator.
