A new decision aid (DA) effectively prepared pregnant women for making informed choices about prenatal screening for trisomy. End-users found the DA useful, though suggestions were made for presentation improvements.
Area of Science:
- Maternal-fetal medicine
- Health decision science
- Patient decision aids
Background:
- Prenatal screening for trisomy involves complex decisions for expectant parents.
- Effective decision aids are crucial for informed choices in maternal healthcare.
Purpose of the Study:
- To evaluate the usefulness and acceptability of a newly developed decision aid (DA) for prenatal screening for trisomy.
- To assess the DA's effectiveness in preparing pregnant women and partners for decision-making.
Main Methods:
- A mixed-methods pilot study was conducted in three prenatal care settings.
- Thirty-nine pregnant women/couples participated, providing feedback via interviews based on the Technology Acceptance Model.
- Data analysis included descriptive statistics and deductive analysis.
Main Results:
- The DA demonstrated high usefulness, with a mean score of 86.2 ± 13.
- A majority found the information amount appropriate (79.5%) and balanced (89.7%).
- Participants rated the DA as very useful (61.5%) but suggested improvements for presentation and values clarification.
Conclusions:
- Pilot testing of decision aids with patients is essential before large-scale clinical implementation.
- The developed DA shows promise in aiding informed decisions regarding prenatal screening for trisomy.
