The demand for genetic services has never been greater. Vast advances in genetic technology, Angelina Jolie’s disclosure that she is a BRCA mutation carrier, and the Supreme Court ruling on gene patents have hurled genetic services into the mainstream. Since the Supreme Court ruling last year, the cost of germline (hereditary) genetic testing has plummeted and now includes panels of genes.
The error rates in ordering and interpreting genetic testing were already high, resulting in incorrect recommendations for surveillance—and even prophylactic surgeries—across the country. The move from single gene testing to multigene panels will, unfortunately, drive this error rate even higher.
Add to this a genetic testing laboratory, desperate to retain a share of the lucrative BRCA testing market, has launched a campaign recruiting mammography technicians with little if any education in genetics, to order genetic testing themselves, and it is easy to predict that the error rate will increase even further.
Some insurance companies, including Cigna, have reacted to the mass misordering and misinterpretation of genetic testing by requiring that their members receive genetic counseling by a certified professional before having certain types of genetic tests. It is not difficult to see how all of these events will cause a logjam in genetics services.
Many premier health centers recognize the dire need for genetics services and are expanding their teams of certified genetic counselors to handle these needs. However, even with these increases, many centers have a wait time of many weeks or months for nonurgent referrals. What can we do to help ease these needs?
Increase the nurse’s role in genetic evaluation
Nurses often have close, repeated contact with patients and their families. They are perfectly positioned to:
Utilize phone counseling for patients who cannot access in-person counseling
Due to distance, long wait times, preference, or because the patient is unable or unwilling to travel, some patients may be better served by utilizing a certified genetic counselor by telephone. There are now several reputable services available that accept health insurance, including:
Understand direct-to-consumer (DTC) genetic testing services
There has been great resistance by healthcare providers to embrace DTC genetic testing services due to concerns about the quality of testing and reporting and the nature of testing offered (SNP-based risk estimates vs. mutation-based; tests with known vs questionable scientific validity and utility).
Some of these concerns have been warranted and have prompted the FDA to examine these practices. These examinations will likely prompt improvements to DTC services.
There is a huge consumer desire for these services, and they will likely continue to increase over time. Oncology nurses can deploy a frontline approach in interpreting DTC testing by:
Genetic services will play an increasingly large role in medical care as we move forward. We will need to continually evaluate new genetic service models while maintaining the highest standards of care to minimize errors and maximize benefits as these exciting new technologies unfold.
