Implementation of pharmacogenomics: Experience at Ochsner Health.

Abstract

Pharmacogenomics is the study of how individual responses to medication are influenced by genetics. As medication experts, pharmacists are uniquely suited to practicing this application of precision medicine. Fundamental operational aspects of developing a pharmacy clinical pharmacogenomics practice are described, and the specific experience of a multisite health system in developing a pharmacogenomics service is discussed. Considerations for the development of a clinical pharmacy-driven pharmacogenomics service include understanding testing selection, targeting the appropriate patient population, exploration of reimbursement, design of the practice, and education of the pharmacogenomics workforce. Testing can be preemptive or reactive, can occur in house or as a send-out service, and can be panel based or specific to a single gene. Pharmacogenomics is applicable to many medicine specialties, making deployment of services to strategic groups essential. Reimbursement for pharmacogenomics is variable and may pose a barrier to implementation. The demand for pharmacogenomics education for pharmacy students and as a formal postgraduate career path is growing. Pharmacogenomics service planning and implementation details for a multisite health system are described. The practice of pharmacogenomics presents a remarkable opportunity for clinical pharmacists and health systems to improve patient care outcomes and experiences.
