Expectations and basic knowledge in ultrasound screening among pregnant women: A questionnaire survey.

ABSTRACT

OBJECTIVE: This study aimed to evaluate the disparity of the expectations and basic knowledge of prenatal ultrasound (US) screening among pregnant women and make a comparison with the current scientific knowledge and national recommendations. We hypothesize that sociodemographic factors, including age, education, and professional occupation, may be associated with different levels of knowledge. METHODS: This was a cross-sectional study performed in 2021 of 336 women aged 18 to 46 years in a maternity facility in a tertiary hospital in Portugal. The main outcome measures were questionnaire data from questions divided into four categories (sociodemographic, expectations, knowledge, and final considerations/suggestions). The data were grouped according to the sociodemographic factors (age, educational level, and professional occupation) and analyzed and compared as a function of the social groups as well as overall tendencies. RESULTS: Our data confirmed a significant discrepancy between the expectations and general knowledge of pregnant women regarding prenatal US when compared with the current scientific knowledge. Importantly, we found that both depended greatly on sociodemographic factors, particularly educational level. This reiterated the importance of conducting effective dissemination actions of current scientific knowledge, focusing on the main objectives of US screening as well as the limitations of the existing technology. CONCLUSION: This study will help in defining strategies for future dissemination actions aiming to improve current practice and lead to a higher synchrony of expectations towards US between couples and practitioners.
