Prenatal iodine supplementation and early childhood neurodevelopment: the PoppiE trial - study protocol for a multicentre randomised controlled trial.

INTRODUCTION: Observational studies suggest both low and high iodine intakes in pregnancy are associated with poorer neurodevelopmental outcomes in children. This raises concern that current universal iodine supplement recommendations for pregnant women in populations considered to be iodine sufficient may negatively impact child neurodevelopment. We aim to determine the effect of reducing iodine intake from supplements for women who have adequate iodine intake from food on the cognitive development of children at 24 months of age. METHODS AND ANALYSIS: A multicentre, randomised, controlled, clinician, researcher and participant blinded trial with two parallel groups. Using a hybrid decentralised clinical trial model, 754 women (377 per group) less than 13 weeks' gestation with an iodine intake of ≥165 µg/day from food will be randomised to receive either a low iodine (20 µg/day) multivitamin and mineral supplement or an identical supplement containing 200) µg/day (amount commonly used in prenatal supplements in Australia), from enrolment until delivery. The primary outcome is the developmental quotient of infants at 24 months of age assessed with the Cognitive Scale of the Bayley Scales of Infant Development, fourth edition. Secondary outcomes include infant language and motor development; behavioural and emotional development; maternal and infant clinical outcomes and health service utilisation of children. Cognitive scores will be compared between groups using linear regression, with adjustment for location of enrolment and the treatment effect described as a mean difference with 95% CI. ETHICS AND DISSEMINATION: Ethical approval has been granted from the Women's and Children's Health Network Research Ethics Committee (HREC/17/WCHN/187). The results of this trial will be presented at scientific conferences and published in peer-reviewed journals. TRIAL REGISTRATION NUMBER: NCT04586348.

Training in obstetric anal sphincter injuries in Australia and New Zealand: A survey of Royal Australian and New Zealand College of Obstetricians and Gynaecologists trainees.

BACKGROUND: Training in obstetric anal sphincter injuries (OASIS) in Australia and New Zealand relies upon consultant teaching and has not previously been assessed. AIMS: The aims of this study are to establish if training in OASIS is consistent and optimal in Australia and New Zealand and to evaluate trainee perspectives on supervision and teaching, along with confidence in repairing OASIS. MATERIALS AND METHODS: A descriptive cross-sectional study was performed. Royal Australian and New Zealand College of Obstetricians and Gynaecologists trainees were sent a 21-question survey. The survey was distributed to 725 trainees, and 132 trainees provided complete responses (18.2%). The main outcome measures were (i) comparison of confidence in performing a caesarean section versus OASIS repair and (ii) descriptive analysis of views towards training and suggestions for improvement. RESULTS: Trainees were significantly more confident in performing a caesarean section independently compared to OASIS repair (P < 0.05). This was the case for all year groups. Confidence increased with each year of training. Only 62% reported credentialing at their site. Whereas 50% reported training at the time of first unsupervised repair as good or excellent, 22.7% felt it was suboptimal and 2.3% unsatisfactory; 75.8% had attended a workshop; 38.6% requested mandatory workshops. Requests included that workshops be yearly, include video training and be required at consultant level. Trainees asked for supervision despite credentialing and for separate credentialing for 3A/B- and 3C/4th-degree tears. CONCLUSIONS: Trainees have increasing confidence in their ability to independently perform OASIS repairs throughout training. They requested that improvements be made to training and that there be an increase in structured teaching.

Induction of labour practices in New South Wales hospitals: Before and after a statewide policy.

Midwifery Unit Managers completed surveys in 2008 and 2014 to determine methods of induction of labour. There was an increase in balloon catheter use for cervical ripening (rate difference 37%, P = 0.007). Currently, all respondent hospitals have an oxytocin protocol; district hospitals had a significant increase in use of post-maturity protocols (rate difference = 40%, P = 0.01) but there was no change in use of prostaglandin protocols.
