Abstract

This document discusses, among other things, systems and methods to enable physician labels on a remote server and use labels to verify and improve algorithm results. A method comprises using patient data in an automated analysis to obtain a result; receiving a message from the user, wherein the message is related to the result; and using at least a portion of the message to automatically modify the analysis.

Claims

1. A method comprising:

receiving, by a transceiver, patient data at a processor-based system from a sensor, the patient data comprising patient physiological data;

using the patient data at the processor-based system in an automated diagnostic technique to obtain a result reflecting a first physiological event, wherein the diagnostic technique is a programmatic code;

communicating the result to a clinician through a user interface;

receiving, by the processor-based system, a message from the clinician, wherein the message includes a clinician observation of the patient;

comparing, by a verification module, the clinician observation to the result to determine that the clinician observation is inconsistent with the result;

modifying, by the processor-based system, the diagnostic technique for a subsequent performance of the diagnostic technique based on comparing the clinician observation to the result, wherein the processor-based system uses the clinician observation to modify the diagnostic technique, and

executing the modified diagnostic technique to obtain a new result.

2. The method of claim 1, wherein the message includes one or more parameters to improve the performance of the diagnostic technique.

3. The method of claim 2, wherein the parameters include one or more of:

a threshold, an indication of a specificity, or an indication of a sensitivity.

4. The method of claim 1, wherein the clinician observation of the patient includes a result of an independent assessment of the patient, wherein the independent patient assessment is used to determine a result that is comparable to the result of the diagnostic technique.

5. The method of claim 1, wherein using the patient data includes determining a patient condition.

6. The method of claim 1, wherein the message is formatted using a standardized interface language.

7. The method of claim 6, wherein the standardized interface language includes XML.

8. The method of claim 1, wherein using the result and the clinician observation to automatically modify the diagnostic technique includes adjusting a sensitivity of the diagnostic technique based on the indication of the accuracy of the result.

9. The method of claim 8, wherein adjusting a sensitivity of the diagnostic technique includes adjusting a threshold used in the diagnostic technique.

10. The method of claim 1, wherein using the result and the clinician observation to automatically modify the diagnostic technique includes adjusting a specificity of the diagnostic technique based on the indication of the accuracy of the result.

11. The method of claim 10, wherein adjusting a specificity of the diagnostic technique includes adjusting a threshold used in the diagnostic technique.

12. The method of claim 1, wherein using the result and the clinician observation comprises:

comparing the result to the clinician observation to obtain a comparison; and

based on the comparison, modifying the diagnostic technique in subsequent performance of the diagnostic technique.

13. A system comprising:

a transceiver adapted to receive patient data from a sensor, the patient data comprising patient physiological data;

a storage device having a programmatic code defining an automated diagnostic technique;

an operating device comprising an analysis module adapted to execute the automated diagnostic technique and to use the patient data in the automated diagnostic technique to obtain a result reflecting risk of a first physiological event;

a user-interface configured to;

communicate the result to a clinician; and

receive a message from the clinician, wherein the message includes a clinician observation of the patient; and

a verification module configured to determine whether the observation is inconsistent with the result, wherein the analysis module is further adapted to use the clinician observation to modify the diagnostic technique for subsequent performance of the diagnostic technique if the message is inconsistent with the result, and wherein the analysis module is further adapted to maintain the diagnostic technique if the message is consistent with the result.

14. The system of claim 13, wherein the message includes one or more parameters to improve the performance of the diagnostic technique.

15. The system of claim 14, wherein the parameters include one or more of:

a threshold, an indication of a specificity, or an indication of a sensitivity.

16. The system of claim 13, wherein the clinician observation of the patient includes a result of an independent assessment of the patient, wherein the independent patient assessment is used to determine a result that is comparable to the result of the diagnostic technique.

17. The system of claim 13, wherein a communication module is included at a central system.

18. The system of claim 13, wherein the analysis module is further adapted to use the patient data to determine a patient condition.

19. The system of claim 13, wherein the analysis module is adapted to adjust at least one of a sensitivity or a specificity of the diagnostic technique based on the result and the clinician observation.

20. The system of claim 13, wherein the analysis module is adapted to:

compare the result to the clinician observation to obtain a comparison; and

based on the comparison, modify the diagnostic technique in subsequent performance of the diagnostic technique.

21. An apparatus comprising:

means for receiving patient data from a sensor, the patient data comprising patient physiological data;

means for using the patient data in an automated diagnostic technique to obtain a result reflecting risk of a first physiological event, wherein the diagnostic technique is a programmatic code;

means for communicating the result to a clinician;

means for receiving a message from the clinician, wherein the message includes a clinician observation of the patient;

means for determining whether the observation is inconsistent with the result;

means for selectively modifying the diagnostic technique using the clinician observation for a subsequent performance of the diagnostic technique if the message is inconsistent with the result, and for executing the modified diagnostic technique to obtain a new result; and

a means for maintaining the current diagnostic technique if the message is consistent with the result.
