Improving Patient Knowledge of Aneuploidy Testing Using an Educational Video: A Randomized Controlled Trial

Area of Science:

• Prenatal diagnostics
• Medical education
• Genetics

Background:

• Aneuploidy testing is crucial for prenatal care.
• Effective patient education is vital for informed decision-making.

Purpose of the Study:

• To assess the efficacy of an educational video in explaining aneuploidy testing options.
• To evaluate the impact of the video on knowledge and understanding among pregnant women.

Main Methods:

• A randomized controlled trial was conducted with pregnant women undergoing aneuploidy testing.
• Participants were stratified by age (<35 and ≥35 years) and randomized to view or not view an educational video.
• Knowledge was assessed using a survey (0-15 score) at baseline and post-appointment.

Main Results:

• Women younger than 35 showed a significant knowledge improvement (+2.0 points) after viewing the video (P=.01).
• Older women (≥35) receiving genetic counseling demonstrated no significant difference in knowledge gain between video and control groups (P=.98).
• Improved understanding was reported by younger women (P<.001), but patient satisfaction remained unchanged across groups.

Conclusions:

• An educational video effectively enhanced knowledge and understanding of aneuploidy testing for women under 35.
• For women 35 and older, genetic counseling appears to provide sufficient information, negating additional benefit from the video.
• Patient-centered educational tools can be valuable in prenatal genetic testing education.
