Informed consent for antenatal serum screening for Down syndrome.

Area of Science:

• Medical Ethics
• Prenatal Diagnostics
• Genetic Counseling

Background:

• Patient autonomy is a key ethical principle in medicine.
• Understanding of antenatal serum screening for Down syndrome is often limited among pregnant women.
• Informed consent requires adequate patient comprehension of screening procedures.

Purpose of the Study:

• To assess pregnant women's perceived understanding of antenatal serum screening for Down syndrome.
• To evaluate the impact of genetic counseling on informed consent and decision-making autonomy.
• To examine the influence of screening on maternal anxiety and depression levels.

Main Methods:

• Randomized controlled trial involving pregnant women (15-21 weeks gestation).
• Experimental group received genetic counseling; control group did not.
• Questionnaires assessed perceived understanding, decision-making autonomy, anxiety, and depression before and after counseling.

Main Results:

• The experimental group demonstrated significantly higher perceived understanding of antenatal serum screening for Down syndrome.
• More women in the experimental group reported making autonomous decisions regarding serum screening.
• No significant differences in anxiety or depression levels were observed between groups.

Conclusions:

• Pregnant women require enhanced information for informed decisions about antenatal serum screening.
• Comprehensive genetic counseling effectively improves autonomy in screening participation decisions.
• Healthcare providers must prioritize ethical informed consent for prenatal screening.
