Summary
Vascular surgeons are willing to use genetic testing for aortopathy patients, but non-academic practices face barriers like cost and access to genetic counselors. Guidelines and education are key to increasing adoption.
Area of Science:
- Cardiovascular Surgery
- Medical Genetics
- Patient Care
Background:
- Physician education in vascular genetics is a priority for engaging patients with aortic dissection.
- A survey of vascular surgeons was conducted to understand their practices, motivations, and barriers concerning genetic testing for aortopathies.
Purpose of the Study:
- To characterize vascular surgeon practice patterns regarding genetic testing for aortopathies.
- To identify motivations and barriers influencing the incorporation of genetic testing in vascular surgery practices.
Main Methods:
- An anonymous 27-question online survey was distributed to vascular surgeons globally.
- Data collected included demographics, genetics education, testing attitudes, utilization, and experiences with genetic vascular aortopathies.
- Statistical analysis, including unpaired t-tests, compared responses based on interest in testing and practice type.
Main Results:
- 171 surgeons responded; 86% were interested in incorporating genetic testing.
- Academic surgeons reported higher rates of caring for patients with genetic aortopathies and access to genetic expertise compared to non-academic surgeons.
- Key barriers identified were insurance coverage, cost, and access to genetic counselors, particularly in non-academic settings.
Conclusions:
- Vascular surgeon attitudes are favorable towards genetic testing for aortopathies.
- Practical challenges, including cost and access to genetic counseling, hinder implementation, especially in non-academic practices.
- Future strategies should prioritize evidence-based guidelines, continuing medical education, and improved access to genetic counseling services.
