Abstract

An apparatus in one example comprises a user wearable, non-encumbering, movement sensor and an analyzer. The user wearable, non-encumbering, movement sensor substantially continuously measures daily-activity data of a patient. The analyzer makes a determination from the daily-activity data of the patient that a change in condition of the patient has occurred. The analyzer generates an indication of the change in condition of the patient for access by a remote caregiver.

Claims

1. An apparatus, comprising:

a user-wearable, non-encumbering, movement sensor that substantially continuously measures daily-activity data of a patient; and

an analyzer that makes a determination from the daily-activity data of the patient that a change in condition of the patient has occurred, wherein the analyzer generates an indication of the change in condition of the patient for access by a remote caregiver.

2. The apparatus of claim 1, wherein the analyzer compares the daily-activity data of the patient with previous-activity data of the patient to make the determination that the change in condition of the patient has occurred.

3. The apparatus of claim 1, wherein the analyzer employs the daily-activity data of the patient and previous-activity data of the patient to look for one or more trends to make the determination that the change in condition of the patient has occurred.

4. The apparatus of claim 1, wherein the analyzer employs the daily-activity data of the patient and activity data of one or more approximately and/or substantially similar patients to make the determination that the change in condition of the patient has occurred.

5. The apparatus of claim 1, wherein the user-wearable, non-encumbering, movement sensor automatically, substantially continuously measures the daily-activity data of the patient;

wherein the analyzer automatically generates the indication of the change in condition of the patient for access by the remote caregiver only upon an automated determination from the daily-activity data of the patient that the patient needs one or more of human investigation, human diagnosis, and/or human treatment.

6. The apparatus of claim 1, wherein the analyzer generates the indication of the change in condition of the patient for access by the remote caregiver upon a determination from the daily-activity data of the patient that the patient has a change in chronic heart failure (CHF) condition.

7. The apparatus of claim 1, wherein the analyzer makes an estimate whether one or more of hospitalization is needed, an acute event is impending, and/or death is impending for the patient.

8. The apparatus of claim 1, wherein the analyzer generates in the indication of the change in condition of the patient for access by the remote caregiver a rank from the daily-activity data of the patient of a need of the patient for medical review.

9. The apparatus of claim 1, wherein the analyzer generates the indication of the change in condition of the patient for access by the remote caregiver upon a determination from the daily-activity data of the patient of likelihood that one or more of hospitalization is needed, an acute event is impending, and/or death is impending for the patient.

10. The apparatus of claim 1, wherein the user-wearable, non-encumbering, movement sensor comprises a user-wearable, non-encumbering, in-home monitor that substantially continuously measures the daily-activity data of the patient.

11. The apparatus of claim 1, further comprising:

a collector that receives the daily-activity data of the patient from the user-wearable, non-encumbering, movement sensor and collects the daily-activity data of the patient on a substantially daily basis as daily-collection data for the patient;

wherein the analyzer generates the indication of the change in condition of the patient for access by the remote caregiver upon a determination from the daily-collection data for the patient that the change in condition of the patient has occurred.

12. The apparatus of claim 11, wherein the user-wearable, non-encumbering, movement sensor and the collector comprise a unitary construction and/or an integral formation.

13. The apparatus of claim 11, wherein the collector stores the daily-activity data of the patient for later transmission when the collector is out of range of a base station that provides the daily-activity data of the patient to the analyzer approximately and/or substantially once per day.

14. The apparatus of claim 1, further comprising:

a transmitter that comprises one of;

a radio transmitter located on a user-wearable, non-encumbering device that comprises the user-wearable, non-encumbering, movement sensor;

or

a base station that provides the daily-activity data of the patient to the analyzer approximately and/or substantially once per day.

15. A method, comprising the steps of:

allowing a patient non-encumbered movement at home while automatically, substantially continuously measuring daily-activity data of the patient;

making a determination automatically from the daily-activity data of the patient whether the patient needs one or more of human investigation, human diagnosis, and/or human treatment; and

generating automatically an alert to a remote caregiver only upon the determination from the daily-activity data of the patient that the patient needs the one or more of human investigation, human diagnosis, and/or human treatment.

16. The method of claim 15, wherein the step of generating automatically the alert to the remote caregiver comprises the step of:

assigning to the patient automatically from the daily-activity data of the patient a ranked need of the patient for the one or more of human investigation, human diagnosis, and/or human treatment in the alert to the remote caregiver.

17. The method of claim 15, further comprising the step of:

displaying to a health care professional automatically a ranked need of the patient for the one or more of human investigation, human diagnosis, and/or human treatment in the alert relative to one or more other ranked needs of corresponding one or more other patients for one or more of human investigation, human diagnosis, and/or human treatment.

18. The method of claim 17, wherein the step of generating automatically the alert to the remote caregiver comprises the steps of:

assigning automatically a priority for one or more of human investigation, human diagnosis, and/or human treatment to one or more selected patients of the patient and the one or more other patients based on the ranked need of the patient and the one or more other ranked needs of the corresponding one or more other patients; and

alerting automatically a medical doctor of the priority for the one or more of human investigation, human diagnosis, and/or human treatment of the one or more selected patients.

19. An article, comprising:

one or more computer-readable signal-bearing media; and

means in the one or more media for making a determination from daily-activity data of a patient allowed freedom of movement at home whether the patient needs one or more of human investigation, human diagnosis, and/or human treatment; and

means in the one or more media for generating an indication of a change in condition of the patient for access by a remote caregiver upon the determination from the daily-activity data of the patient that the patient needs the one or more of human investigation, human diagnosis, and/or human treatment.

20. The article of claim 19, wherein the means in the one or more media for generating the indication of the change in condition of the patient for access by the remote caregiver comprises:

means in the one or more media for assigning a priority for one or more of human investigation, human diagnosis, and/or human treatment to one or more selected patients of the patient and one or more other patients based on a ranked need of the patient and one or more other ranked needs of the one or more other patients; and

means in the one or more media for alerting a medical doctor of the priority for the one or more of human investigation, human diagnosis, and/or human treatment of the one or more selected patients.
