Abstract: A health index system includes a processor receiving an accumulated health data for a patient from a behavior database of a health information system and filtering the accumulated health data into a patient modifiable data by including in the patient modifiable data only data related to clinical and non-clinical patient modifiable behaviors. The processor calculates a health index for the patient from the patient modifiable data and transmits the health index to an index database of the health information system.

Abstract: A health index system comprises a processor which executes a behavior unit, an index unit, and an output unit. The behavior unit is configured to receive an accumulated health data for a patient from a behavior database of a health information system and filter the accumulated health data into a patient modifiable data by including in the patient modifiable data only data related to clinical and non-clinical patient modifiable behaviors. The index unit is configured to receive the patient modifiable data from the behavior unit and calculate a health index for the patient from the patient modifiable data. The output unit is configured to receive the health index from the index unit and transmit the health index to an index database of the health information system.

Abstract: A clinical decision support system enabling sharing of medical knowledge in a machine executable format, implementable as a network-based system in which individual executable knowledge modules (EKMs) define the data requirements for assessing a patient, the conclusions that can be drawn using that data, and instructions on how to generate those conclusions. Using standards-based messages transmitted over a network, client decision support applications provide patient data to the system and receive patient-specific assessments and recommendations. The system permits re-use of executable medical knowledge across diverse applications and care settings, easy authoring of knowledge modules, and use of the system framework to implement decision support applications having significant clinical utility.
