Scientific title
Foetal cardiotocography versus intermittent auscultation during labour ward admission: a randomised controlled trial and qualitative follow-up
Acronym
ADCAR
Study hypothesis
The admission cardiotocograph (ACTG), was introduced as a screening test to try and identify foetuses at greater risk of intrapartum asphyxia that might benefit from continuous electronic foetal monitoring (EFM) during labour. Contrary to recommendations that it should not be used for low-risk women (Royal College of Obstetricians and Gynaecologists [RCOG] 2001), an Irish survey found that routine ACTGs were done in 96% of all maternity units in the Republic of Ireland (Devane, Lalor & Bonner 2007). There have been repeated calls for a thorough evaluation of the ACTG through adequately powered randomised trials. The ADCAR trial is designed to provide this evaluation.
Null Hypothesis:
There is no significant difference between admission cardiotocography (ACTG) and intermittent auscultation (IA) of the foetal heart, in low risk women on admission to the labour ward or labour assessment room in:
1. Caesarean section
2. Obstetric intervention, and
3. Neonatal morbidity
This trial will also explore women's experience of foetal monitoring modalities.

2. Faculty of Health Sciences, Trinity College Dublin, Research Ethics Committee, November 2007
