Abstract

Apparatus for assessing medical risks of a patient includes an analytics engine and equipment that provides data to the analytics engine. The equipment includes a patient support apparatus such as a patient bed, a nurse call computer, a physiological monitor, a patient lift, a locating computer of a locating system, and an incontinence detection pad. The analytics engine analyzes the data from the equipment to determine a sepsis risk score, a falls risk score, and a pressure injury score. The apparatus further include displays that are communicatively coupled to the analytics engine and that display the sepsis, falls, and pressure injury risk scores. The displays include a status board display located at a master nurse station, an in-room display provided by a room station of a nurse call system, an electronic medical records (EMR) display of an EMR computer, and a mobile device display of a mobile device of a caregiver assigned to the patient.

First claim

The invention claimed is:

1. A system for use in a healthcare facility, the system comprising
an analytics engine,
a plurality of equipment providing data to the analytics engine, the data pertaining to a patient in the healthcare facility, the plurality of equipment including at least one of the following: a patient support apparatus, a nurse call computer, a physiological monitor, a patient lift, a locating computer of a locating system, or an incontinence detection pad, wherein the analytics engine analyzes the data from the plurality of equipment to determine in substantially real time each of the following: a first score relating to a risk of the patient developing sepsis, a second score relating to a risk of the patient falling, and a third score relating to a risk of the patient developing a pressure injury,
a computer coupled to the analytics engine and coordinating a caregiver rounding interval at which at least one caregiver assigned to the patient is required to check in on the patient, wherein
when the analytics engine determines the first score, in response to the first score increasing from a first value to a second value, the analytics engine automatically activates an infusion pump for the delivery of IV antibiotics and the computer automatically decreases the caregiver rounding interval;
when the analytics engine determines the second score, in response to the second score increasing from a first value to a second value, the analytics engine automatically activates a bed exit or patient position monitoring system and the computer automatically decreases the caregiver rounding interval; and
when the analytics engine determines the third score, in response to the third score increasing from a first value to a second value, the analytics engine automatically activates an alternating pressure function of a mattress and the computer automatically decreases the caregiver rounding interval; and

wherein the computer automatically increases the caregiver rounding interval in response to the at least one of the first, second, or third scores decreasing from the second value to the first value, and
a mobile device of a caregiver assigned to the patient and configured to receive wireless communications initiated by the analytics engine, the mobile device being configured to generate a screen on a display of the mobile device, the screen including:
a first window having a scoring section that includes a modified early warning score (MEWS) calculated by the analytics engine and one or more vital signs that contribute to the calculation of the MEWS score;
a second window indicating the risk of the patient developing sepsis by displaying the first score calculated by the analytics engine; and
a third window indicating the risk of the patient falling by displaying the second score calculated by the analytics engine,
wherein the screen further includes respective arrow icons that appear adjacent the MEWS, the first score, and the second score to indicate whether the MEWS, the first score, and the second score, respectively, have increased or decreased from a prior reading.

2. The system of claim 1 , further comprising a plurality of additional displays communicatively coupled to the analytics engine and operable to display the first, second, and third scores, the plurality of displays comprising at least two of the following: a status board display located at a master nurse station, an in-room display provided by a room station of a nurse call system, and an electronic medical records (EMR) display of an EMR computer.

3. The system of claim 1 , wherein the plurality of equipment includes at least three of the following: the patient support apparatus, the nurse call computer, the physiological monitor, the patient lift, the locating computer, and the incontinence detection pad.

4. The system of claim 1 , wherein the plurality of equipment includes at least four of the following: the patient support apparatus, the nurse call computer, the physiological monitor, the patient lift, the locating computer, and the incontinence detection pad.

5. The system of claim 1 , wherein the plurality of equipment includes at least five of the following: the patient support apparatus, the nurse call computer, the physiological monitor, the patient lift, the locating computer, and the incontinence detection pad.

6. The system of claim 1 , wherein the plurality of equipment includes all six of the following: the patient support apparatus, the nurse call computer, the physiological monitor, the patient lift, the locating computer, and the incontinence detection pad.

7. The system of claim 1 , wherein each of the first, second, and third scores is normalized by the analytics engine so as to have a minimum value and a maximum value that is common to each of the other first, second, and third scores.

8. The system of claim 7 , wherein the minimum value is 0 for each of the first, second, and third scores.

9. The system of claim 7 , wherein the minimum value is 1 for each of the first, second, and third scores.

10. The system of claim 7 , wherein the maximum value is 5 for each of the first, second, and third scores.

11. The system of claim 1 , wherein the analytics engine also receives additional data from an international pressure ulcer prevalence (IPUP) survey for the patient and analyzes the additional data in connection with determining at least one of the first, second, and third scores.

12. The system of claim 1 , wherein the analytics engine communicates at least two of the first, second, and third scores to at least one piece of equipment of the plurality of equipment.

13. The system of claim 1 , wherein the at least one piece of equipment of the plurality of equipment includes a device display and wherein steps for lowering at least one of the first, second, and third scores is displayed on the device display.

14. The system of claim 1 , wherein the plurality of equipment includes the patient support apparatus and wherein data from the patient support apparatus includes at least one patient vital sign sensed by at least one vital sign sensor integrated into the patient support apparatus.

15. The system of claim 14 , wherein the at least one patient vital sign sensed by the at least one vital sign sensor includes heart rate or respiration rate.

16. The system of claim 14 , wherein data from the patient support apparatus further includes patient weight.

17. The system of claim 1 , wherein the plurality of equipment includes the patient support apparatus and wherein data from the patient support apparatus includes patient weight and a position of the patient on the patient support apparatus.

18. The system of claim 17 , wherein data from the patient support apparatus further includes data indicative of an amount of motion by the patient while supported on the patient support apparatus.

19. The system of claim 1 , wherein the plurality of equipment includes the physiological monitor and wherein data from the physiological monitor includes one or more of the following: heart rate data, electrocardiograph (EKG) data, respiration rate data, patient temperature data, pulse oximetry data, and blood pressure data.

20. The system of claim 1 , wherein the first score is at or near a maximum value if the following criteria exist: i) the patient's temperature is greater than about 38.3° Celsius (C) (about 101° Fahrenheit (F)) or less than about 35.6° C. (about 96° F.), ii) the patient's heart rate is greater than 90 beats per minute; and iii) the
