Abstract

A method comprises determining a person'"'"'s level of risk for developing an adverse condition; selecting a care protocol based on the level of risk; displaying a proposed configuration of a person support structure corresponding to the care protocol for a caregiver to approve; and upon approval by the caregiver, implementing the configuration.

Claims

1. A method of predicting an egress condition for a person supported on a person support structure, the method comprising:

receiving input signals including;

an egress motivating condition which corresponds to at least one of time since last toileting, input/output balance, or lack of catheter;

an egress preparation sequence which corresponds to at least one of patient posture or patient location;

determining if the input signals mimic an egress profile by assigning a numerical value to each of the input signals and including the numerical values in a summation to obtain a summed value which is compared to a predetermined threshold; and

generating an alert if the summed value mimics the egress profile, wherein the input signals include information sensed by a pressure map.

6. The method of claim 1, wherein the pressure map comprises a mat positioned on a mattress of the patient support structure.

7. The method of claim 1, further comprising receiving at least one additional input signal corresponding to a facility input and modifying the alert as a function of the facility input, wherein the facility input includes information corresponding to at least one of the following:

a facility protocol, facility logistics, the patient population, case-mix, culture, facility patterns, risk tolerance, time of day, staffing levels, caregiver round times, or likelihood an alert will be responded to within a predetermined amount of time.

8. The method of claim 1, further comprising communicating the alert to a caregiver via a nurse call system.

2. A method of predicting an egress condition for a person supported on a person support structure, the method comprising:

receiving input signals including;

an egress motivating condition which corresponds to at least one of time since last toileting, input/output balance, or lack of catheter;

an egress preparation sequence which corresponds to at least one of patient posture or patient location;

determining if the input signals mimic an egress profile by assigning a numerical value to each of the input signals and including the numerical values in a summation to obtain a summed value which is compared to a predetermined threshold; and

generating an alert if the summed value mimics the egress profile, wherein the input signals include information sensed by a load cell.

9. The method of claim 2, wherein the load cell is included as part of a bed frame of the patient support structure.

10. The method of claim 2, further comprising receiving at least one additional input signal corresponding to a facility input and modifying the alert as a function of the facility input, wherein the facility input includes information corresponding to at least one of the following:

a facility protocol, facility logistics, the patient population, case-mix, culture, facility patterns, risk tolerance, time of day, staffing levels, caregiver round times, or likelihood an alert will be responded to within a predetermined amount of time.

11. The method of claim 2, further comprising communicating the alert to a caregiver via a nurse call system.

3. A method of predicting an egress condition for a person supported on a person support structure, the method comprising:

receiving input signals including;

an egress motivating condition which corresponds to at least one of time since last toileting, input/output balance, or lack of catheter;

an egress preparation sequence which corresponds to at least one of patient posture or patient location;

determining if the input signals mimic an egress profile by assigning a numerical value to each of the input signals and including the numerical values in a summation to obtain a summed value which is compared to a predetermined threshold; and

generating an alert if the summed value mimics the egress profile, wherein the input signals include information sensed by an image capture device.

12. The method of claim 3, further comprising receiving at least one additional input signal corresponding to a facility input and modifying the alert as a function of the facility input, wherein the facility input includes information corresponding to at least one of the following:

a facility protocol, facility logistics, the patient population, case-mix, culture, facility patterns, risk tolerance, time of day, staffing levels, caregiver round times, or likelihood an alert will be responded to within a predetermined amount of time.

13. The method of claim 3, further comprising communicating the alert to a caregiver via a nurse call system.

4. A method of predicting an egress condition for a person supported on a person support structure, the method comprising:

receiving input signals including;

an egress motivating condition which corresponds to at least one of time since last toileting, input/output balance, or lack of catheter;

an egress preparation sequence which corresponds to at least one of patient posture or patient location;

determining if the input signals mimic an egress profile by assigning a numerical value to each of the input signals and including the numerical values in a summation to obtain a summed value which is compared to a predetermined threshold; and

generating an alert if the summed value mimics the egress profile, wherein the input signals include information sensed by a 3D image sensor.

14. The method of claim 4, further comprising receiving at least one additional input signal corresponding to a facility input and modifying the alert as a function of the facility input, wherein the facility input includes information corresponding to at least one of the following:

a facility protocol, facility logistics, the patient population, case-mix, culture, facility patterns, risk tolerance, time of day, staffing levels, caregiver round times, or likelihood an alert will be responded to within a predetermined amount of time.

15. The method of claim 4, further comprising communicating the alert to a caregiver via a nurse call system.

5. A method of predicting an egress condition for a person supported on a person support structure, the method comprising:

receiving input signals including;

an egress motivating condition which corresponds to at least one of time since last toileting, input/output balance, or lack of catheter;

an egress preparation sequence which corresponds to at least one of patient posture or patient location;

determining if the input signals mimic an egress profile by assigning a numerical value to each of the input signals and including the numerical values in a summation to obtain a summed value which is compared to a predetermined threshold; and

generating an alert if the summed value mimics the egress profile, wherein the input signals include information sensed by an array of sensors and the person support structure includes a mattress, wherein the array of sensors is coupled to the mattress.

16. The method of claim 5, further comprising receiving at least one additional input signal corresponding to a facility input and modifying the alert as a function of the facility input, wherein the facility input includes information corresponding to at least one of the following:

a facility protocol, facility logistics, the patient population, case-mix, culture, facility patterns, risk tolerance, time of day, staffing levels, caregiver round times, or likelihood an alert will be responded to within a predetermined amount of time.

17. The method of claim 5, further comprising communicating the alert to a caregiver via a nurse call system.
