Use of Videos to Improve Patient Knowledge on Prenatal Genetics

The Use of Videos for Informed Consent for Prenatal Genetic Screening: a Randomized Controlled Trial

This is a randomized controlled trial of a low income and low health literacy population of pregnant women from a diverse racial and ethnic background to assess the effectiveness of a pre-visit educational video on prenatal genetic screening and testing options.

During pregnancy, women are routinely counseled about the risks of their offspring to have a chromosomal abnormality or birth defects. Both prenatal screening and diagnostic testing options to exclude aneuploidy should be offered to all pregnant women early in their pregnancy. A standardized educational video on prenatal screening may enhance a patient's understanding and knowledge of testing and support more informed decisions.

The objective of this study is to evaluate and compare patient knowledge scores on prenatal genetic screening before and after a standard prenatal care visit compared to the addition of a pre-appointment educational video.
