Study design details

Study design

Multicenter study (n = 4) analyzing routinely collected data from pseudonymized electronic health records (EHRs) using natural language processing (NLP) for unstructured sources. The algorithm mapped variables to a standard terminology, generating OMOP CDM databases, validated per hospital

Main study objective

- Proof of concept for novel and scalable methodology in CLL
- Characterize clinical and demographic patient profile
- Asses biomarker testing and treatment patterns against evolving guidelines

Setting

Belgium, diagnosis between 2018 and 2021
