Abstract

A method includes receiving an input indicative of at least one factor that contributes to the development of pressure ulcers; determining a risk score as a function of the input; comparing the risk score to a previous risk score; and at least one of activating a therapy configured to reduce the magnitude of the factor and notifying a caregiver if the risk score is greater than the previous risk score.

First claim

The invention claimed is:

1. A method of operating a patient support apparatus, comprising:
receiving a first input indicative of a factor that contributes to the development of pressure ulcers;
determining a first risk score of a person developing a pressure ulcer as a function of the first input;
receiving a second input indicative of the factor that contributes to the development of pressure ulcers;
determining a second risk score of the person developing a pressure ulcer as a function of the second input; and
activating a therapy configured to reduce the magnitude of the factor that contributes to the development of pressure ulcers if the rate of change between the second risk score and the first risk score is greater than a predetermined threshold.

2. The method of claim 1 , wherein the factor that contributes to the development of pressure ulcers includes at least one physiological factor that contributes to skin breakdown.

3. The method of claim 2 , wherein the physiological characteristic that contributes to skin breakdown includes at least one of an interface pressure, a skin temperature, a skin moisture level, an amount of shear, an amount of friction, and an incontinence condition.

4. The method of claim 3 , wherein activating the therapy based on the comparison between the second risk score and the first risk score includes comparing the second risk score to the first risk score and determining that a pressure ulcer is likely to occur when a comparison of the second risk score to the first risk score indicates that the physiological characteristic is increasing over time.

5. The method of claim 3 , wherein activating the therapy based on the comparison between the second risk score and the first risk score includes comparing the second risk score to the first risk score and determining that a pressure ulcer is likely to occur when the comparison of the second risk score to the first risk score indicates that the physiological characteristic exceeds a predetermined threshold for a predetermined period of time.

6. The method of claim 1 , wherein the therapy includes at least one of rotational therapy and low air loss therapy.

7. The method of claim 1 , wherein the therapy is directed toward a targeted location where the pressure ulcer is predicted to occur.

8. The method of claim 1 , wherein the method further comprises determining the first risk score at a first time based on the first input, the first input being from a sensor on a mattress supporting the person, and determining the first risk score further includes using information from the person's record in an electronic medical records system, and wherein the method further comprises determining the second risk score at a second time based on the second input, the second input being from the sensor on a mattress supporting the person, and determining the second risk score further includes using information from the person's record in an electronic medical records system.

9. A method, comprising:
receiving a first input indicative of a factor that contributes to the development of pressure ulcers;
receiving a second input indicative of the factor that contributes to the development of pressure ulcers a predetermined time after receiving the first input;
determining a first risk score as a function of the first input;
determining a second risk score as a function of the second input;
activating a therapy configured to reduce the magnitude of the factor based on a comparison of the second risk score to the first risk score;
receiving a third input indicative of the factor that contributes to the development of pressure ulcers after activating the therapy;
determining a third risk score as a function of the third input; and
modifying the therapy based on a comparison of the third risk score to at least one of the first risk score and the second risk score,
wherein the therapy is modified based on the rate of change of the physical characteristic between the first risk score and the third risk score or the rate of change of the physical characteristic between the second risk score and the third risk score.

10. The method of claim 9 , wherein the factor that contributes to the development of pressure ulcers includes at least one physiological factor that contributes to skin breakdown.

11. The method of claim 10 , wherein the physiological characteristic that contributes to skin breakdown includes at least one of an interface pressure, a skin temperature, a skin moisture level, an amount of shear, an amount of friction, and an incontinence condition.

12. The method of claim 11 , wherein modifying the therapy based a comparison of the third risk score to at least one of the first risk score or second risk score includes determining that a pressure ulcer is likely to occur when the comparison of the third risk score to the first risk score or the second risk score indicates that the physiological characteristic is increasing over time.

13. The method of claim 11 , wherein modifying the therapy based a comparison of the third risk score to at least one of the first risk score or second risk score includes determining that a pressure ulcer is likely to occur when the comparison of the third risk score to the first risk score or the second risk score indicates that the physiological characteristic exceeds a predetermined threshold for a predetermined period of time.

14. The method of claim 9 , wherein the therapy includes at least one of rotational therapy and low air loss therapy targeted at a location where the pressure ulcer is predicted to occur.

15. The method of claim 9 , wherein the method further comprises determining the first risk score at a first time based on the first input, the first input being from a sensor on a mattress supporting the person, and determining the first risk score further includes using information from the person's record in an electronic medical records system, and wherein the method further comprises determining the second risk score at a second time based on the second input, the second input being from the sensor on a mattress supporting the person, and determining the second risk score further includes using information from the person's record in an electronic medical records system.

16. The method of claim 15 , wherein the method further comprises determining the third risk score at a third time based on the third input, the third input being from the sensor on a mattress supporting the person, and determining the third risk score further includes using information from the person's record in an electronic medical records system.

17. The method of claim 9 , wherein the first risk score is determined a first time, the second risk score is determined at a second time after the first time, and the third risk score is determined at a third time after the second time.
