Arms and Interventions
Participant Group / ArmParticipant Group / Arm |
Intervention / TreatmentIntervention / Treatment |
|---|---|
|
Active Comparator: Routine care
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.
|
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.
|
|
Experimental: Experimental
These 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.

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.

Measure Description |
Time Frame |
|---|---|---|
|
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
|
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.

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

Measure Description |
Time Frame |

|
Decisional Conflict Score
Time Frame: At completion of decision aid (Experimental group) and completion of genetic counseling (all participants), approximately 10-60 minutes
|
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.
|
At completion of decision aid (Experimental group) and completion of genetic counseling (all participants), approximately 10-60 minutes
|
|
Test Chosen
Time Frame: At completion of decision aid and at completion genetic counseling, approximately 10-60 minutes
|
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.
|
At completion of decision aid and at completion genetic counseling, approximately 10-60 minutes
|
|
Supplementary Tests Performed
Time Frame: 22 weeks gestation
|
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.
