Primary care providers (PCPs) gain confidence in discussing genetic testing after personal experience. Undergoing direct-to-consumer genetic testing improves PCPs' comfort and interest in genomic medicine applications.

Area of Science:

  • Genomic Medicine
  • Primary Care Practice
  • Medical Education

Background:

  • Primary care providers (PCPs) are crucial for precision medicine adoption.
  • Limited PCP knowledge in genetics/genomics hinders patient counseling and test result interpretation.
  • Direct-to-consumer (DTC) genetic testing offers potential insights but requires informed clinical guidance.

Purpose of the Study:

  • To assess PCPs' baseline knowledge and attitudes towards genetics and DTC testing.
  • To evaluate the impact of personal genetic testing (PGT) on PCPs' confidence and comfort.
  • To understand how PGT influences PCPs' engagement with genomic medicine.

Main Methods:

  • A study involving 130 PCPs who underwent DTC genetic testing via the 23andMe Health + Ancestry Service.

  • Pre- and post-testing surveys assessed awareness, knowledge, attitudes, and confidence in discussing genetic testing.
  • Statistical analysis (p < 0.01) was used to compare pre- and post-testing comfort levels.

    • Main Results:

    • A significant increase in PCPs' comfort discussing genetics as a disease risk factor, from 23% at baseline to 59% after PGT (p < 0.01).
    • Most PCPs (72%) participated to enhance their understanding of genetic testing.
    • A majority (88%) were aware of 23andMe prior to the study.

    Conclusions:

    • Personal genetic testing significantly augments physicians' confidence and comfort with DTC genetic testing.
    • Experiential learning through PGT can enhance PCPs' readiness for integrating genomic medicine into primary care.
    • Further education and practical experiences are vital for empowering PCPs in the precision medicine landscape.
