Does an informational film increase women's possibility to make an informed choice about second trimester ultrasound?

Abstract

Objective: To evaluate effects of an informational film on making an informed choice regarding second trimester ultrasound.

Method: Randomized controlled study. The intervention was an informational film about prenatal examinations. Data were collected at gestational week 26.

Results: A total of 184 women in the intervention group and 206 women in the control group participated in the study. Of those in the intervention group, 81.3% made an informed choice regarding second trimester ultrasound examination compared with 76.1% in the control group (p = 0.21). Women making an informed choice scored higher in knowledge about the examination (p < 0.001), had higher degree of education (p < 0.001), and spoke more frequently Swedish as mother tongue (89.5% vs 74.7%, p = 0.01).

Conclusions: An informational film does not increase women's knowledge or the number of women making an informed choice about the second trimester ultrasound. Women who did not make an informed choice about the second trimester ultrasound had a lower level of education and less knowledge about second trimester ultrasound screening.
