简要总结
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.
详细描述
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.

结局指标
主要结局
Knowledge Score
时间窗: 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.
