Determining prescriptions in electronic healthcare record (EHR) data: methods for development of standardized, reproducible drug codelists

2023-04-17

Abstract excerpt

<h4>ABSTRACT</h4> <h4>Objective</h4> Epidemiological research using electronic healthcare records(EHR) informing everyday patient care uses combinations of codes (“codelists”) to define diseases and prescriptions (or phenotypes). Yet methodology for codelist generation varies, manifesting in misclassification bias, while there are drug-specific codelist considerations. <h4>Materials and Methods</h4> We developed m...
