A new Natural Language Processing (NLP) pipeline standardizes obstetric data, creating a large dataset for improved high-risk pregnancy prediction and resource allocation.

Area of Science:

  • Medical Informatics
  • Obstetrics and Gynecology
  • Data Science

Background:

  • Over 80% of German pregnancies are high-risk, causing inefficient resource allocation.
  • Limited data standardization across clinical databases hinders accurate fetomaternal risk prediction models.

Purpose of the Study:

  • To develop a Natural Language Processing (NLP) pipeline for integrating and standardizing obstetric data.
  • To create a harmonized real-world fetomaternal dataset (FEMAR) for improved risk prediction.

Main Methods:

  • A rule-based NLP pipeline was developed to process structured and unstructured obstetric data.
  • Data was integrated from multiple hospital IT systems, standardizing 449 fetomaternal factors.
  • The FEMAR dataset includes 123,183 unique birth deliveries.

Main Results:

  • Successfully integrated and standardized diverse obstetric data from multiple sources.
  • Created the comprehensive FEMAR dataset, a foundation for advanced predictive modeling.
  • Established a standardized approach to fetomaternal data for future research.

Conclusions:

  • The developed NLP pipeline effectively harmonizes obstetric data, overcoming standardization barriers.
  • The FEMAR dataset provides a robust foundation for developing accurate risk prediction models for pregnancy complications.
  • This work facilitates more efficient resource allocation in high-risk pregnancies.
