Watson for Patient Record Analytics (aka Watson EMRA) - overview


Using Natural Language Processing (NLP) and machine learning to provide intelligent insights from a longitudinal patient record for patient care.

Creating cognitive insights from patient records at the point of care.

Watson for Patient Record Analytics includes:

  • An abstracted patient summary centered around an automatically generated problem list
  • Semantic search that returns clinically meaningful matches on multiple dimensions

The Patient Record

Patient records contain both structured and unstructured data.

Unstructured data is free text – most parts of clinical notes are unstructured data. An older or sicker patient may have hundreds of clinical notes.

Structured data includes medication orders, lab results, procedures, and vitals.

It is typical for a doctor to spend 5 to 10 minutes to review the patient record in order to get a basic understanding of what’s going on with the patient before actually seeing the patient.

Watson Patient Record Analytics

Watson patient record analytics are used on top of the patient record to make sense of the data.

    Watson patient record analytics consist of:
  • NLP: Watson understands the content
  • Synthesis: Watson organizes the data in meaningful ways to help clinicians understand the data
  • Cognitive Insights: Combine patient data and general medical knowledge to provide deeper insight

Problem-Oriented Medical Record (POMR)

POMR has become the de-facto record keeping standard in most US hospitals.

Problem list is also a mandatory section in the CCD (continuity of care), part of HL7's CDA (clinical document architecture) standard.

Quality Assessment of Automatically Generated Problem List

On average Watson found 1.2 very important or important problems missed by physicians per patient record (avg. 6 problems)
