Primary care physicians (PCPs) see value in pharmacogenetic (PGx) testing but lack the confidence and training to use it. Addressing knowledge gaps is crucial for integrating PGx testing into routine patient care.
Area of Science:
- Pharmacogenomics
- Genetics in Medicine
- Primary Care Practice
Background:
- Pharmacogenetic (PGx) testing is expanding, with primary care physicians (PCPs) expected to be key users.
- Understanding PCP training, familiarity, and attitudes is vital for identifying barriers to PGx test adoption.
Purpose of the Study:
- To assess the current training, familiarity, and attitudes of PCPs regarding pharmacogenetic testing.
- To identify barriers to the uptake of PGx testing among PCPs.
Main Methods:
- A national survey was conducted among a sample of primary care physicians.
- Data collected included demographics, awareness of PGx testing, perceived value, comfort level, and prior education.
Main Results:
- The majority of PCPs have heard of PGx testing and believe it will inform drug response.
- Only 13% of PCPs felt comfortable ordering PGx tests, and nearly 25% reported no formal education in pharmacogenetics.
- PCPs recognize their knowledge gaps despite envisioning a significant role in delivering PGx testing.
Conclusions:
- Primary care practitioners acknowledge the importance of PGx testing but face significant knowledge and experience deficits.
- Developing practical guidance and educational tools for PCPs is a high priority to facilitate the integration of PGx testing.
