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

Purpose: To 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.

Methods: A 12-question survey was distributed by email to OB/GYN physicians in the USA. Demographic information was also collected.

Results: A 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.

Conclusion: Significant 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.
