Improving patients' knowledge of the fetal anomaly scan

To determine the level of patient knowledge regarding the 20-week screening ultrasound examination, which is performed on over 95% of women in our unit, and to ascertain whether the use of targeted education could improve patient knowledge and expectations, to determine from where patients obtained information on the scan and to ascertain whether patients felt they had chosen to undergo the scan.

An anonymous questionnaire was issued to all patients attending for their 20-week scan over a 3-week period in July 2002 (n = 220). There were nine questions, focusing on maternal choice, information and knowledge. As a result of the information obtained, we undertook a program of education for hospital and community medical and midwifery staff. A printed information sheet given to the patients at the time of booking their 20-week scan was introduced. We then issued the questionnaire for another 3-week period in July 2003 (n = 171).

As a result of our education program, there was a significant increase in the number of women answering various knowledge-based questions correctly about the 20-week scan, in those using the written information provided as a source of information (P < 0.0001), and in those who felt they had been involved in the decision to have the scan (P = 0.003).

Patients need to be better informed about the 20-week scan, and choose whether or not to have it. Health professionals are pivotal in this process. While written information helps to reinforce the information given, alone it has only a small effect.
