Aneuploidy screening after preimplantation genetic testing: a national survey of physician knowledge and practice

PurposeTo assess the knowledge of generalist OB/GYN providers on aneuploidy screening recommendations for patients who utilized preimplantation genetic testing, and to survey providers' current practice habits.MethodsA 12-question survey was distributed by email to OB/GYN physicians in the USA. Demographic information was also collected.ResultsA total of 178 survey responses were included for analysis. Sixty-seven percent correctly identified the current ACOG recommendation to offer additional aneuploidy screening/invasive diagnostic testing regardless of PGT status, and 66% said their practice is consistent with this recommendation. Ninety-one percent of responders correctly answered that in vitro fertilization does not always include PGT and 63% of responders were able to correctly identify the 3 available types of PGT. Thirty-three percent (n = 58) were attending physicians, and 67% (n = 120) were resident physicians. Most participants (81%, n = 145) stated they have been in practice 0-9 years, and the remaining 19% (n = 33) stated they have been in practice >= 10 years.ConclusionSignificant knowledge gaps of PGT and aneuploidy screening recommendations after PGT exist among generalist OB/GYN physicians. Efforts should be made to educate providers on the importance of offering aneuploidy screening and diagnostic testing to patients who utilized PGT to improve patient care.

Automated summary

This study assessed the knowledge of generalist OB/GYN providers on aneuploidy screening recommendations for patients who utilized preimplantation genetic testing (PGT), and found significant knowledge gaps among physicians. Efforts should be made to educate providers on the importance of offering aneuploidy screening and diagnostic testing to improve patient care.
