Obstetrician-gynecologists' practice and knowledge regarding spina bifida

Area of Science:

• Obstetrics and Gynecology
• Fetal Medicine
• Medical Education

Background:

• Spina bifida is a complex neural tube defect requiring accurate prenatal diagnosis and prognosis.
• Knowledge gaps among obstetricians can impact patient counseling and management.
• Continuing medical education is crucial for healthcare providers.

Purpose of the Study:

• To evaluate the knowledge of practicing obstetrician-gynecologists regarding prenatal diagnosis and postnatal prognosis of spina bifida.
• To identify specific areas where knowledge deficits exist.

Main Methods:

• A written questionnaire was mailed to 1000 randomly selected American College of Obstetricians and Gynecologists Fellows.
• The survey assessed knowledge of sonographic features, stillbirth risk, premature delivery risk, survival rates, and mental retardation incidence.

Main Results:

• Over 50% failed to identify key sonographic features of open neural tube defects.
• Many overestimated stillbirth and premature delivery risks.
• Accuracy in estimating survival rates and mental retardation incidence was suboptimal.
• Maternal-fetal medicine specialists demonstrated better understanding.

Conclusions:

• Significant knowledge gaps exist among obstetrician-gynecologists concerning spina bifida diagnosis and prognosis.
• Enhanced continuing medical education is necessary to improve management of pregnancies with fetal spina bifida.
• Specialists in maternal-fetal medicine show superior knowledge in this area.
