    Description

    The CHA2DS2‐VaSc and HAS‐BLED risk scores are commonly used in the studies of oral anticoagulants (OACs). The best ways to map these scores to the International Classification of Diseases, 10th Revision, Clinical Modification (ICD‐10‐CM) codes is unclear, as is how they perform in various types of OAC users. We aimed to assess the distributions of CHA2DS2‐VaSc and HAS‐BLED scores and C‐statistics for outcome prediction in the ICD‐10‐CM era using different mapping strategies.
