Abstract

A system and method for processing normalized voice feedback for use in automated patient care is described. One or more physiological measures relating to individual patient information and one or more quality of life measures relating to normalized spoken patient self-assessment indicators are retrieved from a patient care record. Each quality of life measure is recorded substantially contemporaneous to the physiological measures. The physiological measures and the contemporaneously recorded quality of life measures retrieved from one such patient care record are analyzed to determine a patient status.

Claims

1. A system for processing normalized voice feedback for use in automated patient care, comprising:

a database storing patient care records with each record containing one or more physiological measures relating to individual patient information and one or more quality of life measures relating to normalized spoken patient self-assessment indicators, each quality of life measure recorded substantially contemporaneous to the physiological measures; and

an analysis module analyzing the physiological measures and the contemporaneously recorded quality of life measures retrieved from one such patient care record to determine a patient status.

2. A system according to

claim 1

, further comprising:

a medical device having a sensor for monitoring and recording the physiological measures from an anatomical site at least one of directly and derivatively.

3. A system according to

claim 2

, further comprising:

at least one further sensor monitoring and recording the physiological measures from an anatomical site unique from the anatomical site monitored by any other such sensor; and

the analysis module determining the patient status by comparing physiological measures retrieved from one such patient care record for a plurality of sensors.

4. A system according to

claim 1

, further comprising:

the database storing patient care records with each record containing physiological measures from sensors monitoring a plurality of anatomical sites within the individual patient; and

the analysis module analyzing the physiological measures from one such patient care record relative to each anatomical site.

5. A system according to

claim 1

, the remote client further comprising:

a feedback device interfacing and recording the quality of life measures from the individual patient.

6. A method for processing normalized voice feedback for use in automated patient care, comprising:

retrieving one or more physiological measures relating to individual patient information and one or more quality of life measures relating to normalized spoken patient self-assessment indicators from a patient care record, each quality of life measure recorded substantially contemporaneous to the physiological measures; and

analyzing the physiological measures and the contemporaneously recorded quality of life measures retrieved from one such patient care record to determine a patient status.

7. A method according to

claim 6

, further comprising:

obtaining the physiological measures from a medical device having a sensor for monitoring the physiological measures from an anatomical site at least one of directly and derivatively.

8. A method according to

claim 7

, further comprising:

obtaining the physiological measures monitored by at least one further sensor monitoring the physiological measures from an anatomical site unique from the anatomical site monitored by any other such sensor; and

determining the patient status by comparing physiological measures retrieved from one such patient care record for a plurality of sensors.

9. A method according to

claim 6

, further comprising:

receiving the physiological measures from sensors monitoring a plurality of anatomical sites within the individual patient from a patient care record; and

analyzing the physiological measures relative to each anatomical site.

10. A method according to

claim 6

, the remote client further comprising:

interfacing and recording the quality of life measures from the individual patient.

11. A computer-readable storage medium for a device holding code for performing the method according to claims 6, 7, 9, and 10.
