<p>This review describes healthcare cost effectiveness/savings for pharmacogenetics (PGx) and relevant clinical outcomes in selected common health conditions. PGx allows targeted drug treatment based on genotype and phenotype. Studies highlight how PGx testing reduces the morbidity and mortality of adverse drug reactions (ADRs) by predicting unexpected drug metabolism due to genetic variation in cytochrome P450 enzymes (CYPs) and drug-drug interactions caused by altered CYP enzyme phenotype. Despite many available PGx testing platforms and PGx-guided treatments, clinical implementation remains challenging and slow due to limited (1) insurance coverage and reimbursement of testing and pharmacist interpretation, (2) outcome data such as evidence showing the benefits of preemptive PGx testing for efficacy or ADR prevention, and (3) promotion of PGx testing among healthcare professionals. Of these, cost is the most significant barrier to patients and the healthcare system. This review describes how PGx testing can be cost effective or cost saving for payors and the healthcare system, especially for depression, cardiovascular disease, and ADRs.</p>

摘要

This review describes healthcare cost effectiveness/savings for pharmacogenetics (PGx) and relevant clinical outcomes in selected common health conditions. PGx allows targeted drug treatment based on genotype and phenotype. Studies highlight how PGx testing reduces the morbidity and mortality of adverse drug reactions (ADRs) by predicting unexpected drug metabolism due to genetic variation in cytochrome P450 enzymes (CYPs) and drug-drug interactions caused by altered CYP enzyme phenotype. Despite many available PGx testing platforms and PGx-guided treatments, clinical implementation remains challenging and slow due to limited (1) insurance coverage and reimbursement of testing and pharmacist interpretation, (2) outcome data such as evidence showing the benefits of preemptive PGx testing for efficacy or ADR prevention, and (3) promotion of PGx testing among healthcare professionals. Of these, cost is the most significant barrier to patients and the healthcare system. This review describes how PGx testing can be cost effective or cost saving for payors and the healthcare system, especially for depression, cardiovascular disease, and ADRs.
