An interactive prenatal testing decision tool improved informed decision-making for fetal aneuploidy screening compared to standard booklets. This tool enhanced knowledge, risk awareness, and satisfaction, leading to better prenatal testing choices.

Area of Science:

  • Medical Genetics
  • Prenatal Diagnostics
  • Health Informatics

Background:

  • Current guidelines recommend offering fetal aneuploidy screening and diagnostic testing to all pregnant women.
  • Informed decision-making requires understanding the differences between various prenatal tests.
  • Patient education is crucial for navigating complex genetic testing options.

Purpose of the Study:

  • To evaluate the impact of a computerized, interactive prenatal testing decision tool on women's decision-making processes.
  • To compare the effectiveness of an interactive tool versus standard educational materials.

Main Methods:

  • A randomized controlled trial involving 496 pregnant women (≤20 weeks gestation).
  • Participants were assigned to either an interactive decision tool or a standard educational booklet.

  • Outcomes included knowledge, risk perception, satisfaction, decisional conflict, and use of invasive testing (in women ≥35 years).

    • Main Results:

    • The interactive tool group demonstrated significantly higher knowledge scores and better risk awareness for miscarriage and Down syndrome.
    • Participants using the tool reported greater satisfaction and less decisional conflict.
    • Among women ≥35 years, the tool influenced the uptake of invasive diagnostic testing based on initial inclinations.

    Conclusions:

    • A computerized, interactive decision tool enhances informed decision-making for prenatal genetic testing.
    • Interactive tools offer a more effective approach to patient education than standard booklets.
    • This technology can empower patients to make more informed choices regarding prenatal screening and diagnostic tests.
