Helping expectant mothers understand inadequate ultrasound images

Abstract

Background Obstetric ultrasound scans may fail to provide all the information that is needed because of poor visualisation. Two main causes of poor visualisation are addressed. These are poor foetal position and poor quality imaging due to beam distortion by overlying fatty tissue. Method To improve communication with patients attending obstetric scans, a poster and leaflet were designed to explain these causes of inadequate scans. A questionnaire was used to assess the value of the poster. Results 57/66 (86%) questionnaires were completed. 52 (91%) found the information on the poster was helpful and well explained. For 8 (14%) the information changed their thoughts about the scan. Conclusion Clear communication aids the expectant mothers understanding of why scans may be suboptimal. The way this is recorded in the scan results is discussed.
