Abstract

Disclosed are various embodiments for equitably assigning medical images for examination. Data describing a medical image study that is pending examination is obtained from a medical data server. The medical image study is assigned for examination by at least one of a plurality of users based on preferences associated with each of the users and a relative complexity value determined for the medical image study. Data describing the assignments is sent to a client. The client is configured to display at least one worklist. Each worklist is associated with a user and describes the one or more medical image studies that have been assigned to the user for examination.

Claims

1. A computer-implemented method, comprising:

obtaining data describing a plurality of medical image studies from at least one medical data server, the plurality of medical image studies pending examination;

determining a relative complexity value for each medical image study using a quantity of relative value units that are based at least in part on an average amount of time to perform a particular type of image study associated with individual ones of the plurality of medical image studies;

assigning each of the plurality of medical image studies for examination by a respective user of a plurality of users based at least in part on preferences associated with the respective user and the relative complexity value determined for each medical image study;

causing a user interface to be rendered by a client device, the user interface including a respective user worklist tab for each of the plurality of users, the respective user worklist tab showing an identifier of the respective user, the respective user worklist tab displaying a listing of medical image studies that have been assigned to the respective user for examination, the user interface further including a pending tab displaying a listing of medical image studies for which examination is pending and that are assigned to any of the plurality of users; and

preventing a user from viewing a particular medical image study based at least in part on a lock status associated with the particular medical image study that indicates that the particular medical image study is being viewed by at least preventing access to image data associated with the particular medical image study stored in a data store.

2. The computer-implemented method of claim 1, wherein the preferences includes a user modality preference comprises at least one of:

computed tomography, magnetic resonance imaging, mammography, nuclear medicine, radiography, positron emission tomography, and ultrasound, and the plurality of medical image studies are assigned further based at least in part on the user modality preference of the respective user.

3. The computer-implemented method of claim 1, wherein assignment of a medical image study of the plurality of medical image studies is not performed until a status associated with the medical image study indicates that all medical images of the medical image study are received and the medical image study is ready for examination.

4. The computer-implemented method of claim 1, further comprising:

receiving the lock status indicating that the particular medical image study is being viewed by a first user; and

causing the lock status to be associated with the particular medical image study, wherein the user that is prevented from viewing the particular medical image study is a second user.

5. The computer-implemented method of claim 1, wherein the respective user worklist tab includes a plurality of rows corresponding to the listing of medical image studies, and wherein user selection of one of the plurality of rows causes a medical image study viewer to be launched for a particular medical image study.

6. The computer-implemented method of claim 1, wherein assigning each of the plurality of medical studies for examination is further based at least in part on a respective schedule of each of the plurality of users.

7. The computer-implemented method of claim 1, wherein causing the user interface to be rendered by the client device further comprises sending data describing the assignments to the client device via a network.

8. The computer-implemented method of claim 1, further comprising:

wherein the quantity of relative value units are further based at least in part on a Medicare relative value scale; and

assigning each of the plurality of medical image studies for examination based at least in part on the quantity of relative value units.

9. The computer-implemented method of claim 1, further comprising generating a list of medical image studies that have not been assigned because they are not ready for examination.

10. A system, comprising:

a server; and

a medical image study assignment application executable in the server, wherein when executed the medical image study assignment application causes the server to at least;

obtain data describing a plurality of medical image studies from at least one medical data server, the plurality of medical image studies pending examination;

determine a relative complexity value for each medical image study using a quantity of relative value units that are based at least in part on an average amount of time to perform a particular type of image study associated with individual ones of the plurality of medical image studies;

assign each of the plurality of medical image studies for examination by a respective user of a plurality of users based at least in part on preferences associated with the respective user and the relative complexity value determined for each medical image study;

cause a user interface to be rendered by a client device, the user interface including a respective user worklist tab for each of the plurality of users, the respective user worklist tab showing an identifier of the respective user, the respective user worklist tab displaying a listing of medical image studies that have been assigned to the respective user for examination, the user interface further including a pending tab displaying a listing of medical image studies for which examination is pending and that are assigned to any of the plurality of users; and

prevent a user from viewing a particular medical image study based at least in part on a lock status associated with the particular medical image study that indicates that the particular medical image study is being viewed by at least preventing access to image data associated with the particular medical image study stored in a data store.

11. The system of claim 10, wherein the preferences includes a user modality preference comprises at least one of:

computed tomography, magnetic resonance imaging, mammography, nuclear medicine, radiography, positron emission tomography, and ultrasound, and the plurality of medical image studies are assigned further based at least in part on the user modality preference of the respective user.

12. The system of claim 10, wherein assignment of a medical image study of the plurality of medical image studies is not performed until a status associated with the medical image study indicates that all medical images of the medical image study are received and the medical image study is ready for examination.

13. The system of claim 10, wherein when executed the medical image study assignment application further causes the server to at least:

receive the lock status indicating that the particular medical image study is being viewed by a first user; and

causing the lock status to be associated with the particular medical image study, wherein the user that is prevented from viewing the particular medical image study is a second user.

14. The system of claim 10, wherein the respective user worklist tab includes a plurality of rows corresponding to the listing of medical image studies, and wherein user selection of one of the plurality of rows causes a medical image study viewer to be launched for a particular medical image study.

15. The system of claim 10, wherein assigning each of the plurality of medical studies for examination is further based at least in part on a respective schedule of each of the plurality of users.

16. The system of claim 10, wherein causing the user interface to be rendered by the client device further comprises sending data describing the assignments to the client device via a network.

17. The system of claim 10, wherein when executed the medical image study assignment application further causes the server to at least:

wherein the quantity of relative value units are further based at least in part on a Medicare relative value scale; and
