Physician knowledge of genetics is improving, especially for recent graduates in relevant specialties. However, gaps persist, necessitating enhanced medical education for accurate genetic test application.

Area of Science:

  • Medical Genetics
  • Medical Education
  • Physician Knowledge Assessment

Background:

  • Assessing physician knowledge of genetics is crucial as genetic testing becomes more prevalent.
  • Understanding factors influencing this knowledge can inform educational strategies.

Purpose of the Study:

  • To evaluate primary care physicians' and psychiatrists' understanding of genetics and genetic tests.
  • To identify factors contributing to variations in their knowledge levels.

Main Methods:

  • A 1991 survey of 1,795 primary care physicians and psychiatrists assessed genetics knowledge and practice characteristics.
  • Statistical analyses included regression to identify significant predictors of knowledge.

Main Results:

  • Physicians answered 73.9% of genetics knowledge items correctly, significantly less than genetics professionals (94.6%).
  • Recency of graduation and practice in genetics-prone specialties were key predictors of higher knowledge.
  • Other factors included U.S. medical school graduation and proactive adoption of new tests.

Conclusions:

  • Physician genetics knowledge is increasing but remains insufficient, particularly regarding genetic tests.
  • While a medical school genetics course helps, it's not enough; comprehensive medical education reform is needed.
  • Enhanced training is vital to minimize physician errors with expanding genetic test availability.
