Use case:
Observational study

Our client needed to fill in a Case Report Form with 70 variables from 2 pathologies, covering at least 5.000 patients from 8 hospitals.

Need
  • Accessing and reading clinical records requires the patient’s informed consent.

  • Manual collection of information bears enormous costs and does not allow to collect the millions of clinical records available.

  • Only between 15-25% of all information contained in hospitals is structured. The rest, is in plain text.

Solution

Data extraction, using Natural Language Processing

Implemented simultaneously in all 10 hospitals participating in the study.
