Maternal factors associated with misperceptions of the second-trimester sonogram

Area of Science:

• Medical Imaging
• Prenatal Diagnostics
• Health Literacy

Background:

• Previous research indicates a significant gap in patient understanding of prenatal screening tests.
• Effective communication of test characteristics is crucial for informed decision-making during pregnancy.

Purpose of the Study:

• To determine the prevalence of misperceptions regarding the sensitivity and safety of second-trimester fetal sonograms.
• To identify maternal demographic and informational factors associated with these misperceptions.

Main Methods:

• A survey was administered to 155 women undergoing routine fetal anatomy scans.
• The survey assessed understanding of ultrasound sensitivity/safety, demographics, and information sources.
• Statistical analyses (univariable and multivariable) identified factors linked to misperceptions.

Main Results:

• Over half (51%) of women exhibited misperceptions about sonogram sensitivity or safety.
• Univariable analysis showed associations with age, ethnicity, education, income, and information source.
• Multivariable regression identified education and income as independent predictors of misperception.

Conclusions:

• Lower educational attainment is significantly associated with a poorer understanding of fetal sonogram capabilities.
• Reduced income levels are also independently linked to misperceptions about ultrasound sensitivity and safety.
• Findings highlight the need for improved patient education strategies regarding prenatal screening.
