Clinical pharmacogenetic testing can be used to guide pharmacotherapy selection or dosing to optimize outcomes. Growing evidence over the past decade has led to the identification of numerous pharmacogenetic associations, which have been integrated across multiple clinical areas, including cardiology, primary care, pain management, surgery, and oncology. Increased access to pharmacogenetic testing via national laboratories and pharmacogenetic testing companies has facilitated uptake and heightened public interest. While clinical adoption of pharmacogenetics has increased, challenges remain, including a lack of clinician confidence in navigating the logistics of testing and applying pharmacogenetics results in patient care; limited reimbursement for testing in some cases; the need for extensive outcomes and economic data; and limited inclusion of testing in clinical guidelines. Future opportunities include the broader use of multigene panels, enhanced clinician training, the integration of pharmacogenetic data within electronic health records, and increased documentation of outcomes data from real-world implementation to support insurance coverage.</p>","PeriodicalId":74256,"journal":{"name":"NEJM evidence","volume":"4 10","pages":"EVIDra2400343"},"PeriodicalIF":0.0,"publicationDate":"2025-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145126723","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Electronic letters emphasizing the cardiovascular benefits of vaccination increased uptake in Denmark; whether this strategy is effective in a diverse U.S. population is unknown.</p><p><strong>Methods: </strong>In this prospective, randomized, open, blinded end point trial involving a multiregional health care system, adults were randomly assigned 1:1:1:1 to receive cardiovascular-focused messaging versus usual care messaging to encourage influenza vaccination at two trial time points, yielding four groups, with each in receipt of either two rounds of cardiovascular-focused nudges; a cardiovascular-focused nudge followed by usual care communication; usual care communication followed by a cardiovascular-focused nudge; or two rounds of usual care communication.
