Abstract

Meta-models are made available to clinical trial protocol designers. A meta-model includes a list of preliminary patient eligibility attributes appropriate for a particular disease category. The protocol designer chooses the appropriate meta-model, and encodes the clinical trial protocol, including eligibility and patient workflow, within the selected meta-model in a protocol database. The resulting protocol database is stored together with databases of other protocols in a library of protocol databases. Sponsors and individual clinical sites have controlled access to the protocols. Study sites make reference to the protocol database in order to perform patient eligibility screening. Once a patient is enrolled into a study, the protocol database indicates to the clinician what workflow tasks are to be performed at each patient visit.

Claims

1. A method for designing a clinical protocol, the method comprising:

creating a plurality of protocol meta-models using a computing device, each of said plurality of protocol meta-models includes at least one list relevant to a designated disease, said at least one list contains a set of patient eligibility criteria and a set of workflow actions, each of said set of patient eligibility criteria includes an attribute associated with the designated disease and an assigned range of values for said attribute to designate if that said patient eligibility criteria is satisfied;

selecting at least one protocol meta-model of said plurality of protocol meta-models using the computing device; and

generating an intelligent clinical protocol database via said computing device using an authoring tool that encodes one or more of said set of patient eligibility criteria and a protocol schema associated with the selected at least one protocol meta-model and that facilitates entry of one or more of said set of workflow actions into the intelligent clinical protocol database.

2. The method of claim 1, wherein said at least one list is represented by a table, said table including one or more categories selected from the group having a disease type, a disease stage, and one or more treatment options.

3. The method of claim 1, wherein said intelligent clinical protocol database is configured to encode significant aspects of the clinical protocol.

4. The method of claim 1, wherein a set of controlled medical terminologies is used when said plurality of protocol meta-models and said intelligent clinical protocol database are created to provide for consistency in the clinical protocol.

5. The method of claim 1, wherein said authoring tool creates a knowledge acquisition tool to add specific features to the intelligent clinical protocol database.

6. The method of claim 1, further comprising an accrual database accessible based on user access controls.

7. The method of claim 1, wherein said plurality of protocol meta-models is distributed by a central authority.

8. The method of claim 1, wherein the clinical protocol is conducted at clinical sites in accordance with the intelligent clinical protocol database.

9. The method of claim 1, wherein the intelligent clinical protocol database is saved in an intelligent clinical protocol database library.

10. The method of claim 1, wherein the intelligent clinical protocol database is saved in a computer readable medium.

11. The method of claim 1, wherein the intelligent clinical protocol database is made available to one or more authorized clinical sites.

12. At least one non-transitory computer readable medium for collectively carrying:

a plurality of protocol meta-models, each of said plurality of protocol meta-models includes a list relevant to a designated disease, said list contains a set of patient eligibility criteria and a set of workflow actions, each of said set of patient eligibility criteria includes an attribute associated with the designated disease and an assigned range of values for said attribute to designate if that said patient eligibility criteria is satisfied; and

an authoring tool to generate an intelligent clinical protocol database, said authoring tool encoding a set of patient eligibility criteria and a protocol schema associated with a selected protocol meta-model into the intelligent clinical protocol database and facilitating entry of specific features of a clinical protocol into the intelligent clinical protocol database;

wherein said intelligent clinical protocol database is generated by;

selecting the protocol meta-model from said plurality of protocol meta-models, including selection of preliminary patient eligibility criteria and workflow actions;

selecting values for individual attributes in said preliminary patient eligibility criteria;

establishing eligibility criteria based on said values selected; and

facilitating entry of a workflow based on said workflow actions selected.

13. The medium of claim 12, wherein said intelligent clinical protocol database is revised by changing one or more individual attributes in said preliminary patient eligibility criteria.

14. The medium of claim 12, wherein said intelligent clinical protocol database is revised by changing one or more eligibility criteria.

15. An article comprising a machine-readable medium storing machine-readable instructions that, when applied to a machine, cause the machine to:

create a plurality of protocol meta-models using a computing device, each of said plurality of protocol meta-models includes at least one list relevant to a designated disease, said at least one list contains a set of patient eligibility criteria and a set of workflow actions, each of said set of patient eligibility criteria includes an attribute associated with the designated disease and an assigned range of values for said attribute to designate if that said patient eligibility criteria is satisfied;

select at least one protocol meta-model of said plurality of protocol meta-models from a using the computing device; and

generate an intelligent clinical protocol database via said computing device using an authoring tool that encodes one or more of said set of patient eligibility criteria and a protocol schema associated with the selected at least one protocol meta-model and that facilitates entry of one or more of said set of workflow actions into the intelligent clinical protocol database.

16. The article of claim 15, wherein the intelligent clinical protocol database is made available to one or more authorized clinical sites.

17. The article of claim 15, wherein said machine graphically displays said intelligent clinical protocol database.
