Public title
The Australian Placental Transfusion Study (APTS): Should very pre term babies receive a placental blood transfusion at birth via deferring cord clamping versus standard cord clamping procedures?
Scientific title
A randomised two arm open label controlled trial comparing standard immediate cord clamping versus deferring cord clamping for 60 seconds or more in babies born less than 30 weeks of gestation to determine which cord clamping method results in improved survival and less disability.

Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
The intervention involves deferring clamping of the cord after birth. The obstetrician or midwife holds the baby as low as possible below the level of the placenta for 60 seconds or more and then clamps the cord 6 cm from the about 6 cm from the umbilicus.
Intervention code [1] 256867 0
Other interventions
Comparator / control treatment
Immediate cord clamping (where the cord is clamped 6 cm from the umbilicus within 10 seconds of the delivery of the baby).
Control group
Active

Outcomes
Primary outcome [1] 258844 0
Composite death and/or major morbidity at 36 completed weeks post menstrual age. Morbidity is defined by one or more of the following: brain injury on ultrasound, severe retinopathy, necrotising enterocolitis, late onset sepsis.

Secondary outcome [3] 265009 0
In 2014, before any follow up outcomes were known, an application APP1086865 was submitted to NHMRC, titled "Does placental transfusion prevent death and disability in very preterm infants? Childhood follow-up in the NHMRC Australian Placental Transfusion Study". The Primary Outcome of the APTS Follow Up Study was defined as death or major disability in the 3rd year after birth (or survival without major disability at 2-3 years). Cerebral palsy, severe visual loss and deafness were determined from hospital records, physical examination or by parent report.

Major disability was defined by a positive result on;
(i) parent report on the Ages and Stages Questionnaire (ASQ),* or, if ASQ is unavailable,
(ii) a modified Short Health Status Questionnaire completed by a medically qualified
practitioner documenting either:-
(a) major developmental delay, including language or speech problems, or
(b) cerebral palsy with inability to walk unassisted at or after 2 yrs corrected age, or
(c) severe visual loss (cannot fixate/ legally blind, or corrected acuity <6/60 in both eyes), or
(d) deafness, requiring a hearing aid or cochlear implants.

The Secondary Outcomes of the APTS Follow Up Study, APP1086865, which were defined before any results of follow up were known, are:-

(1) Death at any time up to 3 years.
(2) Components of major disability at 3 years.
(3) ASQ overall and domain scores

Major disability outcomes were determined from hospital records or physical examination or parent report.

Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
All mothers considered by the attending team to have reasonable chance of dleivering before 30 weeks will be approached for consent. Randomisation and treatment allocation will be completed by a member of the obstetric, neonatal or midwifery team. Central phone randomisation will be used. This is a computerised interactive voice response system.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Randomisation will be performed using an interactive voice response system built by an independent study statistician at the NHMRC Clinical Trials Centre, University of Sydney. All data will be stored securely by the statistical group at the centre.
