Prenatal Screening Decision-Making Facilitated Through An Online Patient Education Module, Erin Atkinson

Dissertations & Theses (Open Access)

As recommendations for prenatal genetic screening are expanded to include patients with pregnancies at low risk for aneuploidy, there is a need to develop accessible mechanisms to promote informed decision-making about genetic screening. The use of patient decision aids has been shown to promote informed decision-making. UTHealth Houston has developed and implemented an online module for pre-test triage for genetic counseling and education of low-risk pregnant patients about genetic screening, called the Prenatal Genetic Education Program (PGEP).

Here, through a retrospective chart review, we characterize the use of PGEP to triage previously presumed low-risk patients to genetic counseling, and whether …

Attitudes Toward And Utilization Of Non-Invasive Prenatal Testing For Chromosome Aneuploidy Among Ob/Gyns, Jessica Davis

Dissertations & Theses (Open Access)

Prenatal diagnosis is traditionally made via invasive procedures such as amniocentesis and chorionic villus sampling (CVS). However, both procedures carry a risk of complications, including miscarriage. Many groups have spent years searching for a way to diagnose a chromosome aneuploidy without putting the fetus or the mother at risk for complications. Non-invasive prenatal testing (NIPT) for chromosome aneuploidy became commercially available in the fall of 2011, with detection rates similar to those of invasive procedures for the common autosomal aneuploidies (Palomaki et al., 2011; Ashoor et al. 2012; Bianchi et al. 2012). Eventually NIPT may become the diagnostic standard of …
