Abstract

A system for improving hospital patient care by generating a Health Score. The system includes an interface module for receiving incoming medical data from a patient, a transformation module for transforming each of the medical datum into a transformed Health Score value, and a combination module for combining the transformed Health Score values corresponding to each of the medical datum into a single Health Score. A presentation and comparison module displays the Health Score as a Health Score plot over a predetermined time frame, such that a user may identify health trends in a patient by evaluating said Health Score plot.

Claims

1. A system for determining overall efficacy of a surgical procedure, a medical treatment or a drug comprising:

an interface module, executing on a computer, for obtaining, over a period of time, incoming disparate medical data relating to a patient who has undergone the surgical procedure, undergone the medical treatment or taken the drug, wherein the incoming disparate medical data includes at least one datum from a nursing assessment, wherein the nursing assessment is performed by a nurse;

a storage module, executing on a computer, for storing historical medical data relating to the patient;

a collection module, executing on a computer, for collecting the incoming disparate medical data from the interface module and for collecting the historical medical data relating to the patient from the storage module;

a transformation module, executing on a computer, for transforming incoming disparate medical data collected at a single point in time into a transformed numerical quantity health score value, wherein each of the transformed numerical quantity health score values is a scaled number in a format for combining together;

a combination module, executing on a computer, for combining each of the transformed numerical quantity health score values into a single health score using a predetermined algorithm, the single health score representing the health of the patient at the single point in time at which the incoming disparate medical data was collected;

a presentation and comparison module, executing on a computer, for continually plotting and displaying on a health score plot single health scores that have been calculated for the patient as a function of time, wherein each of the single health scores displayed at a given point in time are recalculated using any new incoming disparate medical data, wherein the presentation and comparison module displays a statistical reference curve on the health score plot so that the health score plot can be compared to a health score plot of a patient who has undergone the same surgical procedure, undergone the same medical treatment or taken the same drug; and

an alert module, executing on a computer, for alerting a user when a single health score falls below a predetermined threshold, and

wherein, based on the values of the single health scores displayed on the health score plot, the overall efficacy of the surgical procedure, the medical treatment or the drug can be determined.

2. The system of claim 1 wherein the historical medical data relating to the patient is a past single health score.

3. The system of claim 1 wherein the user can modify the algorithm used to generate the single health score based on an illness or condition of the patient.

4. The system of claim 1 wherein the presentation and comparison module displays principal corresponding measurements of direct medical data on the health score plot.

5. The system of claim 1 wherein the at least one datum from the nursing assessment includes at least one of:

respiration, pain, cardiac, gastrointestinal, genitourinary, nutritional, musculoskeletal, skin, Braden score, neurological, psycho-social, peripheral vascular, and safety.

6. The system of claim 1 wherein a user of the system selects which incoming disparate medical data is transformed into a transformed numerical quantity health score value.

7. The system of claim 1 wherein a user of the system selects if weighting factors should be added or multiplied to any of the transformed numerical quantity health score values.

8. A method for determining overall efficacy of a surgical procedure comprising:

generating a health score plot as a function of time for a patient who has undergone the surgical procedure, wherein the health score plot is generated by;

continually obtaining on a computer, over a period of time, incoming disparate medical data relating to the patient, wherein the incoming disparate medical data includes at least one datum from a nursing assessment, wherein the nursing assessment is performed by a nurse;

transforming, on a computer, incoming disparate medical data collected at a single point in time into a transformed numerical quantity health score value, wherein each of the transformed numerical quantity health score values is a scaled number in a format for combining together;

combining, on a computer, each of the transformed numerical quantity health score values into a single health score using a predetermined algorithm, the single health score representing the health of the patient at the single point in time at which the incoming disparate medical data was collected;

generating, on a computer, a health score plot of single health scores that have been calculated for the patient as a function of time, wherein the health score plot includes a statistical reference curve so that the health score plot can be compared to a health score plot of a patient who has undergone the same surgical procedure, and wherein each of the single health scores displayed at a given point in time are recalculated using any new incoming disparate medical data;

determining, based on the values of the single health scores displayed on the health score plot, the overall efficacy of the surgical procedure; and

alerting a user when a single heath score falls below a predetermined threshold.

9. The method of claim 8 wherein the algorithm used to generate the single health score is modified based on an illness or condition of the patient.

10. The method of claim 8 wherein principal corresponding measurements of direct incoming medical data are displayed on the health score plot.

11. The system of claim 8 wherein the at least one datum from the nursing assessment includes at least one of:

respiration, pain, cardiac, gastrointestinal, genitourinary, nutritional, musculoskeletal, skin, Braden score, neurological, psycho-social, peripheral vascular, and safety.

12. The method of claim 8 further comprising:

selecting which incoming disparate medical data is transformed into a transformed numerical quantity health score value.

13. The method of claim 8 further comprising:

selecting if weighting factors should be added or multiplied to any of the transformed numerical quantity health score values.

14. A method for determining overall efficacy of a medical treatment or a drug comprising:

generating a health score plot as a function of time for a patient who has undergone the medical treatment or taken the drug, wherein the health score plot is generated by;

continually obtaining on a computer, over a period of time, incoming disparate medical data relating to the patient, wherein the incoming disparate medical data includes at least one datum from a nursing assessment, wherein the nursing assessment is performed by a nurse;

transforming, on a computer, incoming disparate medical data collected at a single point in time into a transformed numerical quantity health score value, wherein each of the transformed numerical quantity health score values are in a format for combining together;

combining, on a computer, each of the transformed numerical quantity health score values into a single health score using a predetermined algorithm, the single health score representing the health of the patient at the single point in time at which the incoming disparate medical data was collected;

generating, on a computer, a health score plot of single health scores that have been calculated for the patient as a function of time, wherein the health score plot includes a statistical reference curve so that the health score plot can be compared to a health score plot of a patient who has undergone the same medical treatment or taken the same drug, and wherein each of the single health scores displayed at a given point in time are recalculated using any new incoming disparate medical data;

determining, based on the values of the single health scores displayed on the health score plot, the overall efficacy of the medical treatment or the drug; and

alerting a user when a single heath score falls below a predetermined threshold.

15. The method of claim 14 further comprising:

selecting which incoming disparate medical data is transformed into a transformed numerical quantity health score value.

16. The method of claim 14 further comprising:

selecting if weighting factors should be added or multiplied to any of the transformed numerical quantity health score values.
