Study type
Interventional
Description of intervention(s) / exposure
Children born very preterm-at a gestation less than 31 completed weeks- at approximately two weeks prior to discharge from the special care nurseries of Queensland tertiary maternity hospitals were randomised to either the preterm-targeted screening and surveillance group (which was a targeted screening program for disability) or to the National Health Medical Research Council screening program (which is the Australian routine and universal child health program for disability). Both groups screening programs were cordinated by the child's general practitioner. Screening was conducted over the child's first 12-months corrected age of life. General practitioners used the infomation from their respective programs to complete a questionnaire on disability which they returned to the coordinating centre at the Royal Brisbane Women's Hopsital.

Outcomes
Primary outcome [1] 88 0
Agreement (agreed status / disagreed and unsure status) on the primary classification of disability status between general practitioners in both groups (preterm-targeted and National Health Medical Research Council) and the tertiary centre neurodevelopmental assessment at 12-months corrected age conducted in the tertiary centre hospital. Status=disabled will be defined by the neurodevelopmental assessment as the presence of any of: crebral palsy where a child has nonprogressive motor impairment characterized by abnormal muscle tone and movement, developmental delay where a child scored more than 1.0 SD below the standardised test mean assessed with the Revised Griffith Mental Development Scales or the Bayley Scales of Infant Development II - Mental Developmental Intelligence, bilateral blindness if visual acuity in both eyes was worse than 6/60 and deaf if they required aids. Clinicians performing the tertiary assessment were blinded to the child’s trial treatment assignation.
Timepoint [1] 88 0
At 12-months corrected age
Secondary outcome [1] 177 0
Sensitivity analysis.
There were three sensitivity analyses. 1) Agreement on a secondary classification of disability status (<-2SD developmental quoitents, cerebral palsy, bilateral blindness or hearing requiring aids) correctly identified by general practitioner in both groups.
The primary classification of disability was used to test the two general practitioner groups for 2) interrater agreement (agreed status / disagreed ststus)and as a 3) screening instrument.
Timepoint [1] 177 0
Secondary outcome [2] 178 0
1. The effect of the screening and surveillance programs on parental stress and parent-child interaction measured by the Edinburgh Postnatal Depression Scale and the Parenting Stress Index-Short Form
Timepoint [2] 178 0
At 12-months corrected age of the child.
Secondary outcome [3] 179 0
2. Families were asked to document the health services they used including rehospitalisations
Timepoint [3] 179 0
Over the 12-month study period.
Secondary outcome [4] 180 0
3. A locally designed questionnaire on how helpful the assigned program was in assisting with child health was sent to parents and general practitioners
Timepoint [4] 180 0
At completion of the study at 12-months corrected age of the child.

Eligibility
Key inclusion criteria
Infants who met the following criteria were enrolled two weeks prior to discharge from the special care nursery by research assistants from each of Queensland's three tertiary maternity hospitals (The Royal Brisbane Women's Hosiptal RBWH, Mater Mother's Hospital MMH, The Townsville Hospital TTH):Inclusion criteria included: infants (male and female) born at a gestation less than 31 completed weeks, whose family could nominate a general practioner and who would return for follow.

Study design
Purpose of the study
Diagnosis
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Central randomisation by phone
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Block randomisation with random even-numbers between ten and twenty inclusively, stratified for hospital, gestation and social risk factors (two or more of the following: indigenous, single parent, maternal education below school grade 10 or gross weekly household income less than $400.00) were used to assign infants to treatment groups. The first child of a multiple birth was randomised and its siblings automatically assigned to the same group through a central telephone randomisation service. The study investigators were unaware of the block sizes employed and had no access to either the computer or randomisation database.
