Abstract

A computer implemented method for generating a report that includes latent information, comprising receiving an input data stream that includes latent information, performing one of normalization, validation, and extraction of the input data stream, processing the input data stream to identify latent information within the data stream that is required for generation of a particular report, wherein said processing of the input data stream to identify latent information comprises of identifying a relevant portion of the input data stream, bounding the relevant portion of the input data stream, classifying and normalizing the bounded data, activating a relevant report template based on said identified latent information, populating said template with template-specified data, and processing the template-specified data to generate a report.

Claims

1. A method comprising:

collecting an initial set of clinical information from a medical practitioner'"'"'s encounter with a patient, the encounter being of a particular type;

analyzing the initial set of clinical information, using a processor, to correlate the initial set of clinical information with additional information specified by one or more reporting standards as being applicable for documenting the particular type of patient encounter, wherein the additional information corresponds to at least one standard code selected from the group consisting of an ICD code, a CPT code, an E&

M code, and a SNOMED code; and

prompting a user to record the additional information specified by the one or more reporting standards in documenting the patient encounter.

2. The method of claim 1, wherein the collecting comprises extracting the initial set of clinical information from at least a portion of a free-form narration of the patient encounter provided by the medical practitioner.

3. The method of claim 1, wherein the prompting comprises displaying a visual alert to the user.

4. The method of claim 1, wherein the prompting comprises presenting one or more options and allowing the user to choose among the one or more options.

5. The method of claim 4, further comprising:

deriving the additional information from the option chosen by the user; and

storing the additional information in a clinical data repository and/or in an electronic medical record.

6. The method of claim 1, wherein the user is the medical practitioner.

7. The method of claim 1, wherein the determining and the prompting are performed automatically.

8. Apparatus comprising:

a processor; and

a memory storing processor-executable instructions that, when executed by the processor, perform a method comprising;

collecting an initial set of clinical information from a medical practitioner'"'"'s encounter with a patient, the encounter being of a particular type;

analyzing the initial set of clinical information to correlate the initial set of clinical information with additional information specified by one or more reporting standards as being applicable for documenting the particular type of patient encounter, wherein the additional information corresponds to at least one standard code selected from the group consisting of an ICD code, a CPT code, an E&

M code, and a SNOMED code; and

prompting a user to record the additional information specified by the one or more reporting standards in documenting the patient encounter.

9. The apparatus of claim 8, wherein the collecting comprises extracting the initial set of clinical information from at least a portion of a free-form narration of the patient encounter provided by the medical practitioner.

10. The apparatus of claim 8, wherein the prompting comprises displaying a visual alert to the user.

11. The apparatus of claim 8, wherein the prompting comprises presenting one or more options and allowing the user to choose among the one or more options.

12. The apparatus of claim 11, wherein the method further comprises:

deriving the additional information from the option chosen by the user; and

storing the additional information in a clinical data repository and/or in an electronic medical record.

13. The apparatus of claim 8, wherein the user is the medical practitioner.

14. The apparatus of claim 8, wherein the determining and the prompting are performed automatically.

15. A processor-readable medium encoded with processor-readable code that, when executed, performs a method comprising:

collecting an initial set of clinical information from a medical practitioner'"'"'s encounter with a patient, the encounter being of a particular type;

analyzing the initial set of clinical information to correlate the initial set of clinical information with additional information specified by one or more reporting standards as being applicable for documenting the particular type of patient encounter, wherein the additional information corresponds to at least one standard code selected from the group consisting of an ICD code, a CPT code, an E&

M code, and a SNOMED code; and

prompting a user to record the additional information specified by the one or more reporting standards in documenting the patient encounter.

16. The processor-readable medium of claim 15, wherein the collecting comprises extracting the initial set of clinical information from at least a portion of a free-form narration of the patient encounter provided by the medical practitioner.

17. The processor-readable medium of claim 15, wherein the prompting comprises displaying a visual alert to the user.

18. The processor-readable medium of claim 15, wherein the prompting comprises presenting one or more options and allowing the user to choose among the one or more options.

19. The processor-readable medium of claim 18, wherein the method further comprises:

deriving the additional information from the option chosen by the user; and

storing the additional information in a clinical data repository and/or in an electronic medical record.

20. The processor-readable medium of claim 15, wherein the user is the medical practitioner.

21. The processor-readable medium of claim 15, wherein the determining and the alerting prompting are performed automatically.
