Scientific title
Study objectives	1. To establish if Foley catheter balloon cervical dilatation can improve the rates of successful induction of labour in insulin-dependent pregnant diabetic women, and thereby reduce caesarean section rates. 2. To establish whether there is an increase in satisfaction with labour and outcome in women who undergo this new method of inducing labour. 3. To establish whether there are any economic advantages to this new method of induction of labour
Ethics approval(s)	Not provided at time of registration
Health condition(s) or problem(s) studied	Pregnancy and Childbirth: Labour induction
Intervention	Women consenting to participate in the trial will be randomly allocated to one of two groups: 1. Women will be induced at 38 weeks gestation by means of vaginal prostaglandins according to our current labour ward protocol. 2. 24 hrs before planned induction of labour, a Foley balloon catheter will be inserted through the cervical canal and inflated to 30ml, and left in situ for 24 hrs, or until it drops out when the cervix has dilated to 4cm+, which ever occurs earlier. Labour is then induced as per protocol used in women in group 1.
Intervention type	Other
Primary outcome measure	Vaginal delivery versus caesarean section. 1. Clinical: induction success rates, caesarean section rates, length of labour, instrumental delivery, blood loss and neonatal outcomes including Apgar scores, admission to SCBU and blood glucose levels. 2. Psychological: maternal satisfaction rates assessed by a designer questionnaire. 3. Economic: basic costs assessment, including the costs of Foley catheters, additional 24 hour hospital stay, costs of caesarean section etc.
