Abstract

One or more servers and hospital beds are connected to a healthcare network. At least one of the servers includes an event notification module that operates to receive patient EMR information and patient bed configuration information. The patient EMR information is comprised of a patient fall risk profile. At least one of the patient beds includes sensors that transmit messages which include information about the current bed configuration state to the event notification module. The event notification module uses information included in the patient fall risk profile and current bed configuration information to determine whether a patient is at risk of fall out of their bed, and if the patient is at risk, generates an alert message that is sent to a call station or hospital worker.

Claims

linking a plurality of hospital beds over a network to a healthcare system;

wherein the hospital beds comprise one or more sensors to monitor one or more hospital bed properties, the sensors operative to detect a state of each hospital bed property and to generate a signal indicative of the state of each hospital bed property for transmission over the network to the healthcare system; and

wherein the healthcare system comprises one or more servers each of which have non-transitory computer storage for maintaining at least one patient electronic medical record, for maintaining information relating to a current hospital bed properties configuration received from at least one hospital bed, and for storing computer program logic to assess a patients risk of falling;

creating a fall risk profile for the patient, and using information in the patient'"'"'s fall risk profile to determine a minimum hospital bed properties configuration necessary to mitigate the patient'"'"'s risk of falling;

storing information associated with the patient'"'"'s minimum hospital bed properties configuration in the at least one patient electronic medical record maintained by the healthcare system;

configuring properties of a hospital bed assigned to the patient to comply with the minimum hospital bed properties configuration information stored in the patient'"'"'s electronic medical record;

detecting a current state of the properties associated with the patient hospital bed and sending information indicative of the detected property states over the network to the healthcare system; and

the healthcare system generating and sending an alert over the network to one or more hospital workers indicating an elevated patient fall risk if the computer program logic determines that current hospital bed property configuration status information indicates that the patient is present in the hospital bed and the information does not meet the minimum hospital bed properties configuration necessary to mitigate the patient fall risk.

2. The method of claim 1, further comprising the healthcare worker modifying the current hospital bed property configuration to meet the minimum hospital bed properties configuration and the healthcare system detected the modification to the current hospital bed properties.

3. The method of claim 2, further comprising the healthcare system cancelling the alert sent to the one or more hospital workers or sending a second alert to the one or more healthcare workers indicating that the patient is no longer at risk of falling.

4. The method of claim 1, wherein the one or more hospital bed properties is comprised of one or more bed rail type identities, bed height sensing, bed tilt sensing, and patient weight and position sensing.

5. The method of claim 1, wherein the one or more hospital bed property states comprise any one or more of the location of the hospital bed, the position of one or more bed rails, the elevation of the bed surface with respect to a surface upon which the bed rests, and whether a patient is currently in the bed, their weight and position on the bed surface.

6. The method of claim 1, wherein the electronic medical record comprises any one or more of the identity of the patient, the identity of the hospital bed assigned to the patient, the location of the hospital bed, and patient fall risk profile.

7. The method of claim 1, wherein the computer program logic operates on information comprising the minimum hospital bed properties configuration, the patient fall risk profile and the current state of the patient hospital bed properties.

8. The method of claim 1, wherein the patient fall risk profile is comprised of the patient identity and a generic fall risk type or the patient identity, one or more patient fall risk criteria and a minimum bed properties configuration.

9. The method of claim 8, wherein the one or more patient fall risk criteria is comprised a description of symptoms affecting the patients mobility or ambulatory characteristics.

10. The method of claim 9, wherein the symptoms comprise one or both of a physical and physiological characteristic.

11. The method of claim 10, wherein the minimum hospital bed properties configuration comprises a listing of the state of one or more bed properties that are necessary to mitigate the patient fall risk.

12. The method of claim 1, wherein the current state of the patient hospital bed properties changes every time at least one hospital bed property changes.

13. A method of alerting one or more healthcare workers to a hospital bed properties configuration which elevates a fall risk for a patient, comprising:

linking a plurality of hospital beds over a network to a healthcare system;

wherein the hospital beds comprise one or more sensors to monitor one or more hospital bed properties, the sensors operative to detect the state of each hospital bed property and to generate a signal indicative of the state of each hospital bed property for transmission over the network to the healthcare system; and

wherein the healthcare system comprises one or more servers each of which have non-transitory computer storage for maintaining at least one patient electronic medical record and for maintaining information relating to a current hospital bed properties configuration received from at least one hospital bed, each of the one or more servers being programmed to assess a patients risk of falling;

defining a plurality of generic fall risk types each of which type is indicative of the degree to which a patient is at risk of falling;

assigning a set of bed property states to each generic fall risk type, the set of bed property states representing a minimum bed properties configuration necessary to mitigate the patients risk of falling;

creating a fall risk profile for the patient, and assigning, based upon information comprising the patient'"'"'s fall risk profile, an appropriate one of the plurality of the generic fall risk types to the patient and entering the patients generic fall risk type into the patient'"'"'s electronic medical record maintained by the healthcare system;

assigning the patient to one of the plurality of the hospital beds and configuring the state of each hospital bed property to be the same as the property states associated with the patient'"'"'s generic fall risk type stored in their electronic medical record;

detecting a current state of the properties associated with the patient'"'"'s hospital bed and sending information indicative of the detected property states to the healthcare system; and

the healthcare system generating and sending to one or more hospital workers an alert indicating an elevated patient fall risk if the current hospital bed property configuration state information indicates that the patient is present in the hospital bed and the information does not meet the minimum hospital bed properties configuration necessary to mitigate the patient fall risk.

14. The method of claim 13, further comprising the healthcare worker modifying the current hospital bed property configuration to meet the minimum hospital bed properties configuration and the healthcare system detected the modification to the current hospital bed properties.

15. The method of claim 14, further comprising the healthcare system cancelling the alert sent to the one or more hospital workers or sending a second alert to the one or more healthcare workers indicating that the patient is no longer at risk of falling.

16. The method of claim 14, wherein the patient fall risk profile is comprised of the patient identity and a generic fall risk type or the patient identity, one or more patient fall risk criteria and a minimum bed properties configuration.
