Abstract

Some embodiments of the invention provide an automated method for continuously monitoring at least one patient. The method continuously collects medical data about the patient from several different inputs. The method integrates the collected data, and continuously computes at least one severity score for the patient based on the integrated data. The method uses the severity scores to continuously monitor the patient. In some embodiments, integrating the data includes formatting the data so that that the data can be used to compute the severity score. Formatting the data in some embodiments includes using a set of database tables to convert the data. In some embodiments, the database tables are modifiable by a user. Some embodiments continuously compute multiple severity scores. The severity scores computed in some embodiments include the APACHE II score, the SAPS II score, the MEWS score, or user-defined severity scores.

Claims

1. An automated method of continuously monitoring at least one patient, the method comprising:

a) continuously collecting medical data about the patient from a plurality of different inputs;

b) continuously computing at least one severity score for the patient based on the integrated data;

c) using the computed severity scores to continuously monitor the patient.

2. The method of claim 1, wherein computing the at least one severity score comprises formatting the data from the plurality of different inputs so that the data can be used to compute the at least one severity score.

3. The method of claim 2, wherein formatting the data comprises using a set of database tables to convert the data.

4. The method of claim 1, wherein one of the inputs is a real-time heart rate monitor.

5. The method of claim 1, wherein one of the inputs is a lab report stored on a hospital information system.

6. The method of claim 1, wherein multiple severity scores are continuously computed.

7. The method of claim 1, wherein one of the severity scores is the APACHE II score.

8. The method of claim 1, wherein one of the severity scores is the SAPS II score.

9. The method of claim 1, wherein one of the severity scores is the MEWS score.

10. The method of claim 1, wherein one of the severity scores is user-defined.

11. The method of claim 10, wherein a user defines the user-defined severity score by defining a set of database tables.

12. The method of claim 1 further comprising receiving user feedback about the at least one severity score.

13. The method of claim 12 further comprising modifying the at least one severity score based on the user feedback.

14. The method of claim 13, wherein the severity score is modified by machine-learning.

15. The method of claim 13, wherein the severity score is modified by a user.

16. A method for assessing a patient, the method comprising:

a) receiving medical data about the patient from a set of data sources, wherein the medical data comprises data points from a plurality of times;

b) for each data source, selecting a data point to associate with a particular time; and

c) computing at least one severity score for the particular time based on the selected data points.

17. The method of claim 16, wherein computing a severity score comprises:

a) mapping each data point to an integer score; and

b) summing the integer scores to compute the severity score.

18. The method of claim 16, wherein computing at least one severity score comprises computing multiple severity scores.

19. The method of claim 16, wherein for a particular data source, the data point selected is the lowest data point for a specified amount of time prior to the particular time.

20. The method of claim 19, wherein data points resulting from noise are not selected.

21. The method of claim 16, wherein for a particular data source, the data point selected is the highest data point for a specified amount of time prior to the particular time.

22. The method of claim 16, wherein the medical data is received and the at least one severity score is computed in real-time.

23. The method of claim 16, wherein selecting a data point for a particular data source comprises utilizing user feedback to determine the optimal data point to select.

24. The method of claim 16, wherein the medical data comprises non-real-time data, and the at least one severity score is computed retrospectively.
