Claims31
A computer based system for assessing the impact of an ailment on a health related quality of life (HRQOL) domain of a patient, wherein said HRQOL domain comprises a plurality of indicators of functional health and well being, comprising:
- a test module for generating a customized test having a plurality of questions for said patient to determine the impact of said ailment on said HRQOL domain, wherein each question comprises an indicator of functional health and well being as a result of said ailment, wherein said indicator is stably scaled across ailments whose impact is to be assessed to establish a standardized common metric for comparing the impact of various ailments;
- and
- an evaluation module for evaluating, after each question, answers provided by said patient to estimate an ailment impact score and a confidence level in the accuracy of said estimated score;
- and
- wherein said evaluation module is operable to control said test module to dynamically modify said test if said estimated confidence level is outside a pre-determined threshold.
A method of assessing the impact of an ailment on a health related quality of life (HRQOL) domain of a patient, wherein said HRQOL domain comprises a plurality of indicators of functional health and well being, comprising the steps of:
- generating a customized test having a plurality of questions for said patient to determine the impact of said ailment on said HRQOL domain, wherein each question comprises an indicator of functional health and well being as a result of said ailment, wherein said indicator is stably scaled across ailments whose impact is to be assessed to establish a standardized common metric for comparing the impact of various ailments;
- evaluating, after each question, answers provided by said patient to estimate an ailment impact score and a confidence level in the accuracy of said estimated score;
- and
- dynamically modifying said test if said estimated confidence level is outside a predetermined threshold.
A computer readable medium comprising code for assessing the impact of an ailment on a health related quality of life (HRQOL) domain of a patient, wherein said HRQOL domain comprises a plurality of indicators of functional health and well being, said code comprising instructions for:
- generating a customized test having a plurality of questions for said patient to determine the impact of said ailment on said HRQOL domain, wherein each question comprises an indicator of functional health and well being as a result of said ailment, wherein said indicator is stably scaled across ailments whose impact is to be assessed to establish a standardized common metric for comparing the impact of various ailments;
- evaluating, after each question, answers provided by said patient to estimate an ailment impact score and a confidence level in the accuracy of said estimated score;
- and
- dynamically modifying said test if said estimated confidence level is outside a pre-determined threshold.
