Abstract

A dynamic decision forest may be used to guide clinical or other decision queries such that multiple decision trees are followed in sequence and jumps occur between decision trees based on previously received query responses and the system'"'"'s determination of what useful data has not been gathered. For example, rather than storing data concerning all possible paths between various decision trees, a system using the dynamic decision forest may determine at the time of use that a jump should occur from one decision tree to another decision tree despite the system not being pre-populated with data representative of a relationship between the source and destination of the jump. A clinical note may be created based on the path followed through the dynamic decision forest, and iterative verification may be used in order to improve the likelihood that the correct path is being followed.

Claims

1. A method for generating a natural language clinical note, the method comprising:

storing query data corresponding to a first plurality of clinical queries, each clinical query comprising a clinical inquiry and a plurality of associated response options;

providing, to a user, a first clinical query by transmitting data corresponding to both (1) said first clinical query'"'"'s clinical inquiry and (2) at least some of said first clinical query'"'"'s associated response options;

storing said first response data;

providing, to said user, a second clinical query by transmitting data corresponding to both (1) said second clinical query'"'"'s clinical inquiry and (2) at least some of said second clinical query'"'"'s associated response options, wherein said second clinical query is selected based at least in part on said first response data and said query data does not include any predefined relationship between said first clinical query and said second clinical query;

receiving second response data representative of said user'"'"'s selection of one or more of said second clinical query'"'"'s associated response options;

storing said second response data;

generating medical note data representative of said stored first response data and second response data, said medical note data in a natural language format; and

providing to said user said medical note data;

said method performed in its entirety by a computer system.

2. The method of claim 1, further comprising:

providing, to said user, verification data representative of said first response data and said second response data; and

receiving, from said user, modification data indicative of said user'"'"'s selection to change the selected one or more of said first clinical query'"'"'s associated response options.

3. The method of claim 1, further comprising:

providing said user with the ability to enter text corresponding to said medical note data; and

storing user text data representative of said text entered by said user.

4. The method of claim 1, wherein said providing, to a user, a first clinical query comprises transmitting data corresponding to all of said first clinical query'"'"'s associated response options.

5. The method of claim 1, wherein said providing, to a user, a first clinical query comprises transmitting data corresponding to some, but not all, of said first clinical query'"'"'s associated response options.

6. The method of claim 1, wherein said data corresponding to both (1) said first clinical query'"'"'s clinical inquiry and (2) at least some of said first clinical query'"'"'s associated response options is formatted to be processed by a web browser.

7. The method of claim 1, wherein said data corresponding to at least some of said first clinical query'"'"'s associated response options is formatted for touch-based user interaction.

8. The method of claim 1, wherein said query data indicates a second plurality of clinical queries including some but not all of said first plurality of clinical queries, and wherein said second clinical query was selected based at least in part on its presence in said second plurality of clinical queries.

9. The method of claim 1, wherein said query data is stored on a server and said first response data is received by the server from a client device used by said user.

10. The method of claim 1, further comprising generating diagnosis data characteristic of a clinical diagnosis, wherein said diagnosis data is based at least in part on said first response data and said second response data.

11. A system for generating a natural language clinical note, the system comprising:

a query data store configured to store query data corresponding to a first plurality of clinical queries, each clinical query comprising a clinical inquiry and a plurality of associated response options;

a query service configured to provide, to a user, a first clinical query by transmitting data corresponding to both (1) said first clinical query'"'"'s clinical inquiry and (2) at least some of said first clinical query'"'"'s associated response options, and a second clinical query by transmitting data corresponding to both (3) said second clinical query'"'"'s clinical inquiry and (4) at least some of said second clinical query'"'"'s associated response options;

a response service configured to receive first response data representative of said user'"'"'s selection of one or more of said first clinical query'"'"'s associated response options and second response data representative of said user'"'"'s selection of one or more of said second clinical query'"'"'s associated response options;

a response data store configured to store response data; and

a note service configured to generate medical note data representative of said stored first response data and second response data, said medical note data in a natural language format;

wherein said second clinical query was selected based at least in part on said first response data and said query data does not include any predefined relationship between said first clinical query and said second clinical query.

12. The system of claim 11, further comprising:

providing, to said user, verification data representative of said first response data and said second response data; and

receiving, from said user, modification data indicative of said user'"'"'s selection to change the selected one or more of said first clinical query'"'"'s associated response options.

13. The system of claim 11, further comprising:

providing said user with the ability to enter text corresponding to said medical note data; and

storing user text data representative of said text entered by said user.

14. The system of claim 11, wherein said query service is configured to transmit data corresponding to all of said first clinical query'"'"'s associated response options.

15. The system of claim 11, wherein said query service is configured to transmit data corresponding to some, but not all, of said first clinical query'"'"'s associated response options.

16. The system of claim 11, wherein said data corresponding to both (1) said first clinical query'"'"'s clinical inquiry and (2) at least some of said first clinical query'"'"'s associated response options is formatted to be processed by a web browser.

17. The system of claim 11, wherein said data corresponding to at least some of said first clinical query'"'"'s associated response options is formatted for touch-based user interaction.

18. The system of claim 11, wherein said query data indicates a second plurality of clinical queries including some but not all of said first plurality of clinical queries, and wherein said second clinical query was selected based at least in part on its presence in said second plurality of clinical queries.

19. The system of claim 11, wherein said query data store is within a server and said response service is configured to receive response data at the server, from a client device used by said user.
