Genes and medications implemented at St. Jude Children’s Research Hospital. Test results for some genes (e.g., CYP2C19; yellow bars) were implemented as early as 2013, but CDS for additional drugs was implemented over time for different drugs (clopidogrel in 2013, voriconazole in 2015, and proton pump inhibitors in 2017). Abbreviation: CDS, clinical decision support.
