Bias in obtaining broad consent in a German general practice? – Preliminary results from a cross-sectional study

The growing importance of collecting Broad Consent (BC) for research utilizing electronic health records in Germany has brought attention to the need for a deeper understanding of potential selection bias in the process. Since 2020, the BeoNet-Halle outpatient database has been collecting anonymous and pseudonymous patient data from primary care and specialty practices throughout Germany, with the practice being an integral part of this data collection effort. The primary objective of the pilot study is to explore potential socioeconomic discrepancies between patients who provided BC and the general practice population.
