A semi-supervised approach for rapidly creating clinical biomarker phenotypes in the UK Biobank, across different primary care EHR and clinical terminology systems.
The UK Biobank is making primary care electronic health records available for the entire cohort for COVID-19 research. This repository provides machine-readable versions (CSV files) of electronic health record phenotyping algorithms for 31 commonly-measured biomakers, many of which are associated with COVID-19 comorbidities such as body mass index, cardiovascular disease and respiratory disease.
Details on how these algorithms were bootstrapped and validated can be found in the publication:
