Is this trial a fit for you?

Likely a good fit

Ideal candidates for this study are pregnant women who delivered at University College London Hospitals from 2019 onwards.

Probably not a fit

Patients with incomplete medical records or those who delivered at other trusts will not benefit from this study.

What this trial studies

This observational study aims to develop and validate a deep learning model to predict the risk of preterm birth and other adverse pregnancy outcomes by analyzing data from 18,000 patients at University College London Hospital Trust. The research team, composed of experts in various fields, will link electronic health records with data on air pollution exposure to identify significant interactions affecting pregnancy outcomes. By utilizing advanced machine learning techniques, the study seeks to improve the accuracy of preterm birth predictions, which currently lack comprehensive clinical data.

Why it matters

Potential benefit: If successful, this study could lead to better prediction and prevention strategies for preterm birth, ultimately improving maternal and neonatal health outcomes.

How similar studies have gone: Other studies have shown promise in using machine learning for predicting pregnancy outcomes, but this specific approach linking air pollution data is relatively novel.

Inclusion Criteria:

* We aim to include data from pregnant women who delivered at University College London Hospitals from 2019 onwards after the start of the EPIC electronic patient record. The is no specified age range for this study, so as to improve inclusivity. We also aim to represent minority ethnic groups and patients with social deprivation within our dataset.

Exclusion Criteria:

* We will exclude data from patients with an incomplete duration of follow-up due to transfer of antenatal care for delivery at another trust. Patients with incomplete past obstetric history data, inaccurate estimations of gestational age (e.g. due to late booking of the pregnancy) and missing data for 'postcode of usual address' will also be excluded. Patients who are less than 18 years of age will be excluded.
