Abstract

A medical information decision support system is provided, the decision support system including a decision triad. The decision triad includes an information/directives repository operatively connected to an adaptive chart and a decision module via a decision generator wherein the decision generator determines options for providing medical service to a patient based on information from the information/directives repository, the adaptive chart and input from a user.

Claims

1. A medical information decision support system comprising a decision triad, the decision triad including an information/directives repository operatively connected to an adaptive chart and to a decision module via a decision generator wherein the decision generator determines options for providing service to a patient based on information from the information/directives repository, the adaptive chart and input from a user.

2. The system as in claim 1 wherein the information/directives repository and adaptive chart are relational databases.

3. The system claimed in claim 1 wherein the decision module displays weighted choices and recommended advisories in response to user input.

4. The system as in claim 3 wherein each weighted choice includes a computed weight of the probability of accuracy of the weighted choice presented, the computed weight determined by the decision generator from current data from the adaptive chart and repository.

5. The system as in claim 4 wherein selection of a weighted choice or recommended advisory by a user displays further weighted choices or recommended advisories determined by the decision generator from current data from the adaptive chart and repository.

6. The system as claimed claim 3 wherein each weighted choice and recommended advisory is linked to references and summaries of relevant information in the repository.

7. The system as claimed in claim 1 wherein the adaptive chart is operatively connected to an electronic medical record (EMR).

8. The system as claimed in claim 1 wherein the adaptive chart is operatively connected to a laboratory for data entry into the adaptive chart.

9. The system as claimed in claim 3 wherein an RA is dynamically linked to the adaptive chart module and user selection of an RA displays a data entry form on the adaptive chart.

10. The system as claimed in claim 1 wherein the repository includes referenced, standardized summaries of medical information including any one of or a combination of policy and position statements, clinical practice guidelines and formulary statements and/or interpretational clinical directives including any one of or a combination of differential diagnosis trees, treatment algorithms, care-maps and management protocols.

11. The system as claimed in claim 10 wherein the adaptive chart displays trends in clinical data based on current and historical patient data and determined by the decision generator.

13. A system as in claim 12 wherein the decision generator provides instructions to a tree rendering engine for displaying a limited number of decision options to the user.

14. A system as in claim 12 wherein the decision generator provides instructions to a chart engine to display relevant data from the situation-specific database and for user-entry of data into the situation-specific database.

15. A system as in claim 12 wherein the decision generator provides instructions to a general information database engine to display information relevant to a specific situation from the general information database.

18. A decision support system as in claim 1 wherein user selection of a decision module option or entry of data into the adaptive chart provides an update of the information displayed in the information/directives repository, the adaptive chart or the decision module.

19. A decision support system as in claim 1 further comprising an uploading module for uploading information to the information/directives repository and wherein the decision generator can access the uploaded information.

12. A system for supporting decision-making comprising:

a general information database operatively connected to a situation-specific database and a decision tree through a decision generator, the decision generator for determining decision options for presentation to a user through application of general information database rules to situation-specific database rules.

16. An interface for displaying information for assisting a user in a decision-making process comprising a concurrent display of a decision tree, a general information database and a situation-specific database wherein the decision tree display presents options to a user which upon selection of a specific option updates the general information database display and situation-specific database display to display information relevant to the selected option.

17. A method of assisting a user in a decision-making process comprising the steps of concurrently displaying a portion of a decision tree, a general information database and a situation-specific database wherein the decision tree display presents options to a user which upon selection of a specific option updates the general information database display and situation-specific database display to display information relevant to the selected option only.

20. Computer readable media containing the method of claim 17.
