Physicians frequently lack knowledge regarding genetic testing but are eager for training. Patient inquiries and access to genetic counselors significantly influence ordering genetic tests.
Area of Science:
- Medical Genetics
- Clinical Practice
- Physician Education
Background:
- Physician decision-making regarding genetic testing remains unclear.
- Understanding factors influencing genetic test ordering is crucial for clinical practice.
Purpose of the Study:
- To investigate internists' utilization of genetic testing.
- To identify factors affecting physicians' decisions to order genetic tests.
- To assess physicians' perceived knowledge gaps and training needs in genetic testing.
Main Methods:
- A survey was administered to 220 internists at two academic medical centers.
- Data collected included genetic test utilization, counseling practices, referrals, and perceived knowledge.
- Statistical analysis, including multiple logistic regression, was used to identify associated factors.
Main Results:
- Factor V Leiden and Breast/Ovarian Cancer were the most frequently ordered genetic tests.
- A significant percentage of physicians reported ordering genetic tests (44%) and counseling patients (65%).
- Physicians expressed poor knowledge of genetics and testing guidelines, highlighting a need for training.
Conclusions:
- Physicians acknowledge their knowledge deficits in genetic testing and express a strong interest in further education.
- Patient inquiries and the availability of genetic specialists are key drivers for ordering genetic tests.
- Improving physician education on genetic testing is essential for advancing personalized medicine.
