This paper presents the development and pilot testing of an evidence-based decision-aid for pregnant women who have experienced previous caesarean section and who are considering options for birth in a subsequent pregnancy. The Ottawa Decision Support Framework (DSF) has been utilised and modified in the development of a tailored booklet entitled "Birth Choices: What is best for you...vaginal or caesarean birth?" Development included a review by women who had experienced previous caesarean birth as well as obstetric, midwifery and educational experts. The booklet was also reviewed for acceptability by 21 pregnant women who were facing this birth decision. Pre- and post-booklet preferences for birth were elicited and compared to actual birth outcomes. This decision-aid shows promise in facilitating informed decision-making in pregnancy. It is currently undergoing an evaluation in a multi-centre randomised controlled trial.
