Abstract

A method and computer program for interfacing an expert system to a clinical information system. Embodiments of the invention provide tight integration of the systems permitting a clinician to use the functionality provided by the expert system without specifically maintaining separate patient data. They provide a method for communication between the expert system and one or more clinical information systems. This communication permits flow of information and actions between the expert system and the clinical systems and allows maintenance of audit logs in both systems.

Claims

at the expert system, receiving an order; and

sending the order to a clinical module.

6. The method of claim 5, further comprising updating an audit log at the expert system.

7. The method of claim 1, wherein sending the alert to the clinical system comprises pushing the alert from the expert system.

8. The method of claim 1, wherein sending the alert to the clinical system comprises:

receiving a request or query from the clinical system; and

sending the alert to the clinical system in response to the request or query.

9. The method of claim 1, wherein the alert comprises data elements, the method further comprising attaching standard identifiers to at least a portion of the data elements.

10. The method of claim 1, further comprising structuring messages comprising the alert according to proprietary message definitions.

11. The method of claim 1, further comprising structuring messages comprising the alert according to industry standard message definitions.

12. The method of claim 11, further comprising structuring messages comprising the alert according HL7 protocol.

13. The method of claim 1, wherein receiving clinical data from the clinical system comprises receiving clinical data from an interface engine disposed on a clinical module within the clinical system.

14. A computer readable medium having computer executable instructions for performing the steps of claim 1.

15. At an expert system separate from a clinical system and configured to communicate with the clinical system, a method of providing clinical decision support, notwithstanding that the separate expert system and the clinical system are configured to process data having different and otherwise incompatible data formats, the method comprising:

receiving an order on at least one of a synchronous alert interface and an inbound data interface, from the clinical system, the order having a first format structured for compatible processing at the clinical system;

modifying the structure of the order to a second different format structured for compatible processing at the separate expert system such that the order can be compatibly processed at the separate expert system, wherein without the structural modification of the order the separate expert system is unable to compatibly process the order;

processing the modified order to generate a response to the order, the response having the second different data format structured for compatible processing at the separate expert system;

modifying the structure of the response to the first format such that the response can be compatible processed at the clinical system, wherein without the structural modification of the response the clinical system is unable to compatibly process the response; and

sending the modified response to the clinical system on at least one of the synchronous alert interface, an outbound data interface and an outbound orders interface.

16. The method of claim 15, wherein the response is an alert, the method further comprising:

receiving audit information from the clinical system on at least one of a inbound audit interface, inbound data interface and an audit action alert interface when the alert has been dismissed at the clinical system; and

updating an audit log in the expert system.

17. The method of claim 15, wherein the response is an alert, the method further comprising:

receiving audit information from the clinical system on at least one of a inbound audit interface, inbound data interface and an audit action alert interface when the alert results in an addition or change to the orders at the clinical system; and

updating an audit log in the expert system.

18. The method of claim 15, wherein the order comprises data elements, the method further comprising assigning standard identifiers to at least a portion of the data elements.

19. The method of claim 15, further comprising structuring messages comprising the response according to proprietary message definitions.

20. The method of claim 15, further comprising structuring messages comprising the response according to industry standard message definitions.

21. The method of claim 20, further comprising structuring messages comprising the response according to HL7 protocol.

22. A computer readable medium having computer executable instruction for performing the steps of claim 15.

23.
