DOAC ADRs Retrospective Study

Using the latest next generation sequencing tools, this study will evaluate adverse drug reactions (ADRs) (e.g., major bleeding or treatment failure) in study participants while on direct oral anticoagulants (DOACs). A web-based program will analyze the data obtain from sequencing, and generate a drug safety score (DSS). The DSS risk score will be compared with pre-specified serious ADRs associated with DOAC therapy. A secondary analysis will involve discovery of novel variants that arise from our analysis and may potentially affect the outcome of DOAC treatment.
