Official Title

Use of a Novel Decision Aid for Prenatal Aneuploidy Screening

Brief Summary

      The investigators aim to assess whether use of a novel, tablet-based computerized decision
      aid for aneuploidy screening is similar to routine care with a brief genetic counseling visit
      in improving patient knowledge and decreasing decisional conflict.

Detailed Description

      184 women will be randomized in a 1:1 fashion to use of a novel computerized iPad-based
      decision aid in addition to routine counseling or routine counseling only during a single
      study visit. This decision aid was developed at a 10th grade literacy level using input from
      Maternal Fetal Medicine physicians and certified genetic counselors, and piloted by 20
      English and Spanish speaking women of varying education levels. Following completion of
      genetic counseling, participants will complete several surveys assessing knowledge and
      decision conflict. Data will be abstracted regarding demographics, screening and diagnostic
      testing uptake, and testing results.

Study Arms / Comparison Groups

 Routine care
Description:  These patients will receive routine care at our institution for counseling on aneuploidy screening; they will be counseled by a genetic counselor on options, and following counseling, will select their test of choice. All patients will complete a knowledge and demographics questionnaire prior to genetic counseling. Patients in this arm will then complete a knowledge and decisional conflict survey immediately following genetic counseling.
