Abstract

A method and system which numerically quantifies a person'"'"'s loss of quality of life (QOL), i.e., the value of remaining life, due to the occurrence of an injury. The system includes a processor in communication with a health-related QOL measures (e.g., health state utility value) database. Raw data are inputted into the processor. The raw data provide information regarding the person'"'"'s life expectancy and health state before and after the occurrence of the injury. The processor calculates a reference value of the person'"'"'s QOL as if the injury did not occur. The processor then calculates the person'"'"'s actual loss of value of QOL due to the occurrence of the injury. Finally, the processor calculates a QOL disability index by dividing the person'"'"'s actual loss of value of QOL by the reference value. The QOL disability index is used to determine an amount of monetary damages to be awarded in a tort case.

Claims

1. A computer-implemented method of numerically quantifying a person'"'"'s loss of quality of life (QOL) due to the occurrence of an injury, the method being implemented in a system including a processor in communication with a health-related QOL measures database, the method comprising:

(a) inputting raw data into the processor, the raw data providing information regarding the person'"'"'s life expectancy and health state before and after the occurrence of the injury;

(b) the processor calculating a reference value of the person'"'"'s remaining QOL as if the injury did not occur, using information included in the raw data regarding the person'"'"'s life expectancy, health state prior to the occurrence of the injury, and one or more health-related QOL measures obtained from the database;

(c) the processor calculating the person'"'"'s actual loss of value of QOL due to the occurrence of the injury, using the reference value, information in the raw data regarding the person'"'"'s life expectancy and health state after the occurrence of the injury, and one or more health-related QOL measures obtained from the database; and

(d) the processor calculating a QOL disability index by dividing the person'"'"'s actual loss of value of QOL by the reference value, wherein the QOL disability index numerically quantifies the person'"'"'s loss of QOL due to the occurrence of the injury.

2. The method of claim 1 wherein the QOL disability index is used to determine an amount of monetary damages to be awarded in a tort case.

3. The method of claim 1 wherein each of the health health-related QOL measures is determined based on a ratio of (i) a proportion of remaining time of life a surveyed person would be willing to forfeit living in exchange for eliminating a loss of value of QOL, and (ii) the amount of time that the surveyed person expects to experience the loss of value of QOL.

4. The method of claim 1 wherein each of the health-related QOL measures is based on the opinions of a plurality of surveyed people who experienced a loss of value of QOL similar to the person'"'"'s loss of value of QOL.

5. The method of claim 1 wherein the raw data include one or more parameters which indicate a period of time for each of one or more injury recovery phases that the person experiences.

6. The method of claim 1 wherein each of the health-related QOL measures obtained from the database is multiplied by the duration of a health state associated with the health-related QOL measure experienced by the person to indicate at least a portion of the extent of the person'"'"'s loss of value of QOL.

7. The method of claim 1 where the health-related QOL measures include at least one health state utility value.

8. A system for numerically quantifying a person'"'"'s loss of quality of life (QOL) due to the occurrence of an injury, the system comprising:

(a) a processor;

(b) a health-related QOL measures database in communication with the processor; and

(c) a user interface in communication with the processor, the user interface being used to input raw data into the processor, the raw data providing information regarding the person'"'"'s life expectancy and health state before and after the occurrence of the injury, wherein the processor;

(I) calculates a reference value of the person'"'"'s QOL as if the injury did not occur, using information included in the raw data regarding the person'"'"'s life expectancy, health state prior to the occurrence of the injury, and one or more health-related QOL measures obtained from the database;

(II) calculates the person'"'"'s actual loss of value of QOL due to the occurrence of the injury, using the reference value, information in the raw data regarding the person'"'"'s life expectancy and health state after the occurrence of the injury, and one or more health-related QOL measures obtained from the database; and

(III) calculates a QOL disability index by dividing the person'"'"'s actual loss of value of QOL by the reference value, wherein the QOL disability index numerically quantifies the person'"'"'s loss of QOL due to the occurrence of the injury.

9. The system of claim 8 wherein the QOL disability index is used to determine an amount of monetary damages to be awarded in a tort case.

10. The system of claim 8 wherein each of the health-related QOL measures is determined based on a ratio of (i) an proportion of remaining time of life a surveyed person would be willing to forfeit living in exchange for eliminating a loss of value of QOL, and (ii) the amount of time that the surveyed person expects to experience the loss of value of QOL.

11. The system of claim 8 wherein each of the health-related QOL measures is based on the opinions of a plurality of surveyed people who experienced a loss of value of QOL similar to the person'"'"'s loss of value of QOL.

12. The system of claim 8 wherein the raw data includes one or more parameters which indicate a period of time for each of one or more injury recovery phases that the person experiences.

13. The system of claim 8 wherein each of the health-related QOL measures obtained from the database is multiplied by the duration of a health state associated with the health-related QOL measure experienced by the person to indicate at least a portion of the extent of the person'"'"'s loss of value of QOL.

14. The system of claim 8 where the health-related QOL measures include at least one health state utility value.
