An Australian mainstream genetic testing program: Clinicians views about current and future practices

Area of Science:

• Oncology
• Clinical Genetics
• Health Services Research

Background:

• Germline genetic testing is crucial for guiding oncology treatment decisions.
• Mainstream genetic testing, arranged by non-genetics specialists, is increasingly offered to cancer patients.
• Understanding clinician perspectives is vital for the success of mainstreaming initiatives.

Purpose of the Study:

• To evaluate clinician views on the established mainstream genetic testing program for ovarian, breast, prostate, and endometrial cancers.
• To assess clinician interest in adopting mainstream genetic testing practices.

Main Methods:

• A repeated cross-sectional study utilizing web-based surveys in two health districts across seven hospitals in NSW.
• Data collected from 54 participating clinicians (70% response rate).

Main Results:

• Clinicians already using mainstream testing (n=30) reported high satisfaction (76%), finding it time-efficient and accessible.
• A significant majority (88%) of clinicians not yet engaged (n=24) expressed interest in learning more.
• Identified barriers include time constraints, knowledge maintenance, and the consenting/counseling process.

Conclusions:

• The mainstreaming program is perceived by clinicians as a valuable approach for germline testing in oncology patients.
• Ongoing education and accessible resources are essential for the continued success and expansion of the program.
