Abstract

Pharmacogenetic testing has potential to transform healthcare, yet implementation strategies have been limited to major academic medical centers serving metropolitan communities and large health systems. In contrast, rural, community-based health systems are slow to implement these advances, threatening to exacerbate existing healthcare disparities for rural populations. A majority of Montanans live in rural areas, with unique challenges in providing access to pharmacogenetics.

We have established partnerships with three clinical sites who serve rural, underserved populations including American Indian, pediatric, and low socioeconomic status patients. We conducted a needs assessment for pharmacogenetic testing implementation by interviewing 48 key stakeholders. Interview questions were centered around participants opinions regarding pharmacogenetics and their perceived barriers and facilitators for implementation of testing. A codebook was created by analysis and organization of common themes.

Positive opinions on using pharmacogenetics to guide therapy were common. Perceived benefits included reduced time to symptom management, fewer adverse events, and improved adherence. Concerns expressed in similar studies based in larger medical centers were also present, including conflicts with reimbursement and test turnaround time. Unique concerns for vulnerable, underserved populations included equitable access based on socioeconomic status and sensitivity to culture and historical injustices, particularly for tribal people. Participants were enthusiastic about using telehealth to implement pharmacogenetics in these communities. This will provide an innovative strategy for pharmacogenetic testing and consultations.

Participants were eager to implement testing in their facilities. Many concerns can be mitigated with a strategic implementation plan targeted for underserved patients. Our model will implement pharmacogenetics using a telehealth delivery model centered at the University of Montana with outreach to rural health systems and providers. This has the potential to expand as new health innovations are translated into practice. Future work in this area will involve assisting partner sites with implementation efforts and measuring clinical outcomes related to testing services. Our study will help overcome the unique challenges in delivering pharmacogenetics to rural and underserved communities and we aim to provide a model for states with similar patient populations. Our goal is to pave the way for equitable access to pharmacogenetics for all.
