Abstract

A method, and corresponding system (300), for monitoring patients based on activity state and posture. Activity state and/or posture of a patient are measured. Further, one or more vital signs of the patient are measured according to a schedule. Based on the measured activity state and/or posture of the patient and the measured one or more vital signs, the schedule is adjusted and/or patient deterioration is monitored for.

Claims

1. A medical system comprising:

at least one processor programmed to;

measure activity state and/or posture of a patient;

measure one or more vital signs of the patient according to a schedule; and

based on the measured activity state and/or posture of the patient and the measured one or more vital signs, at least one of adjust the schedule and monitor for patient deterioration.

2. The medical system according to claim 1, wherein the schedule includes a measurement frequency for each of the one or more vital signs, and wherein the at least one processor is further programmed to:

determine a patient deterioration score for each of the one or more vital signs from corresponding vital sign measurements; and

adjust the measurement frequency for each of the one or more vital signs based on changes in the corresponding patient deterioration score.

3. The medical system according to claim 2, wherein the at least one processor is further programmed to:

determine a cumulative deterioration patient score from the one or more patient deterioration scores of the one or more vital signs; and

at least one of;

adjust the measurement frequency for each of the one or more vital signs based on the cumulative deterioration patient score; and

adjust an individual scoring scheme of the patient including vital sign thresholds and a list of measured vital signs.

4. The medical system according to claim 1, wherein the at least one processor is further programmed to:

determine a patient deterioration score from the vital sign measurements; and

based on changes in the patient deterioration score, at least one of adjust the schedule and generate a notification;

in response to a charge in the patient deterioration score, re-measuring one or more vital signs to confirm the change; and

in response to confirmation of the change and based on the change, at least one of adjust the schedule and generate a notification.

6. The medical system according to claim 4, wherein the at least one processor is further programmed to:

delay the re-measuring of the one or more vital signs until activity state and/or posture matches a predetermined activity state and/or posture.

7. The medical system according to claim 1, wherein the at least one processor is further programmed to:

instruct the patient to take a predetermined activity state and/or posture before measuring one or more vital signs.

8. The medical system according to claim 1, wherein the at least one processor is further programmed to at least one of:

discard vital sign measurements made when corresponding activity state and/or posture does not match a predetermined activity state and/or posture; and

delay a scheduled measurement until activity state and/or posture matches a predetermined activity state and/or posture.

9. The medical system according to claim 1, wherein the at least one processor is further programmed to:

display a vital sign measurement and the corresponding activity state and/or posture, the corresponding activity state and/or posture displayed adjacent the vital sign measurement.

10. The medical system according to claim 1, wherein the at least one processor is further programmed to:

calculate a posture trend;

compare the posture trend to an expected posture trend; and

display an indication that the posture trend is as expected, that the posture trend is not as expected, and/or that action should be taken, such as turning the patient, based on the posture trend.

5. (canceled)

11. A medical method comprising:

measuring activity state and/or posture of a patient;

measuring one or more vital signs of the patient according to a schedule; and

based on the measured activity state and/or posture of the patient and the measured one or more vital signs, at least one of adjusting the schedule and monitoring for patient deterioration.

12. The medical method according to claim 11, wherein the schedule includes a measurement frequency for each of the one or more vital signs, and wherein said medical method further includes:

determining a patient deterioration score for each of the one or more vital signs from corresponding vital sign measurements; and

adjusting the measurement frequency for each of the one or more vital signs based on changes in the corresponding patient deterioration score.

13. The medical method according to claim 11, further including:

determining a patient deterioration score from the vital sign measurements; and

based on changes in the patient deterioration score, at least one of adjusting the schedule and generating a notification;

in response to a charge in the patient deterioration score, re-measuring one or more vital signs to confirm the change; and

in response to confirmation of the change and based on the change, at least one of adjusting the schedule and generating a notification.

15. The medical method according to claim 13, further including:

delaying the re-measurement of the one or more vital signs until activity state and/or posture matches a predetermined activity state and/or posture.

16. The medical method according to claim 11, further including:

instructing the patient to take a predetermined activity state and/or posture before measuring one or more vital signs.

17. The medical method according to claim 11, further including at least one of:

discarding vital sign measurements made when corresponding activity state and/or posture does not match a predetermined activity state and/or posture; and

delaying a scheduled measurement until activity state and/or posture matches a predetermined activity state and/or posture.
