About this study

Official title: Use of a Novel Decision Aid for Prenatal Aneuploidy Screening

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.

Read the 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.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • iPad-based decision aidOther

    This is a novel decision aid developed by genetic counselors and Maternal Fetal Medicine physicians. It is used via an iPad and is interactive. It is available in English and Spanish has been piloted by 20 English and Spanish speaking women. It takes approximately 15 minutes to complete.

  • Genetic counseling appointmentOther

    All participants will undergo an approximately 15 minute educational genetic counseling appointment regarding aneuploidy screening options. Should family history concerns be identified on intake, this visit may be extended to include a discussion of additional issues.

Study groups in NCT02991729
Study groupRoleWhat they receive
Routine careActive comparatorThese 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.
Receives: Other: Genetic counseling appointment
ExperimentalExperimentalThese patients will use an iPad-based decision aid explaining options for aneuploidy screening and testing. They will then immediately be counseled by a genetic counselor on their options as is routine at our institution, 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 following use of the decision aid, and again immediately following genetic counseling.
Receives: Other: iPad-based decision aid; Other: Genetic counseling appointment

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Knowledge Score

    All patients in the intervention arm will complete a knowledge questionnaire following completion of the decision and and again immediately following genetic counseling. The investigators will assess noninferiority of the decision aid on participant knowledge, with primary outcome comparing knowledge after completion of the decision aid in the intervention arm, to knowledge following genetic counseling only in the routine care arm. The questionnaire is a modification of the validated Maternal Serum Screening Knowledge Questionnaire. This is on a 12-point scale (values 0-12), with higher score indicating greater knowledge.

    Measured: At completion of genetic counseling for the Routine Care Group and at completion of decision aid and genetic counseling for Experimental Group, approximately 10-60 minutes

Secondary outcomes (3)
  1. Decisional Conflict Score

    A low-literacy decisional conflict questionnaire will be used. This will be completed by patients in the intervention arm following use of the decision and and again following genetic counseling. It will be completed by patients in the routine care arm following genetic counseling. Decisional conflict at all time points will be compared - specifically, decisional conflict following decision aid completion in the Experimental Group will be compared to decisional conflict following genetic counseling in the Routine Care Group, and decisional conflict following both decision aid completion and genetic counseling in the Experimental Group will be compared to decisional conflict following genetic counseling in the Routine Care Group. This questionnaire is on a 40 point scale (values 0-40), with higher score indicating higher level of decisional conflict.

    Measured: At completion of decision aid (Experimental group) and completion of genetic counseling (all participants), approximately 10-60 minutes

  2. Test Chosen

    For participants in the intervention arm, initial choice of aneuploidy screening following use of the decision aid will be compared to final test chosen following genetic counseling.

    Measured: At completion of decision aid and at completion genetic counseling, approximately 10-60 minutes

  3. Supplementary Tests Performed

    Use of additional aneuploidy screening or testing modalities (cell-free DNA, chorionic villus sampling, or amniocentesis in addition to initial screening test) in the current pregnancy will be assessed up to 22 weeks gestation.

    Measured: 22 weeks gestation

Questions about this trial

What is this clinical trial studying?

A study testing iPad-based decision aid and Genetic counseling appointment in people with Aneuploidy and Pregnancy Complications, run by University of North Carolina, Chapel Hill at 1 site in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 3 inclusion and 3 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

What does the primary outcome measure?

Knowledge Score (time frame: At completion of genetic counseling for the Routine Care Group and at completion of decision aid and genetic counseling for Experimental Group, approximately 10-60 minutes). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
