15Revised sample size
16Neonatal sepsis, inflammation and
anti-inflammatory therapies
- Neonatal inflammation is an important determinant
of white matter damage - IVIG has multiple immuno-modulatory properties
- IVIG is an important candidate as an
anti-inflammatory therapy in neonatal sepsis
17Reviews of the evidence that perinatal
inflammation predisposes to neonatal brain damage
- Inflammation and preterm birth
- John Newnham
- Inflammation and the developing human brain
- Don Peebles
- Antenatal inflammation consequences for neonatal
immunology - Alan Jobe
18- Can a 500 g baby mount an over-inflammatory
response?
19YES, plasma TNF level gt 1000 pg/ml
20- INIS is addressing a major research question
- Does IVIG reduce mortality and morbidity in
infants with suspected or proven neonatal
infection? -
21A CONSENT DVD DESIGNED TO IMPROVE CONSENT UPTAKE
TO RANDOMISED CONTROLLED TRIALS IN
NEONATOLOGYA PILOT STUDY IN THE INIS NETWORK
- Priya Duggal-Beri, Phyllis Butow, Wendy Hague ,
Val Gebski, Lorraine ORegan, William
Tarnow-Mordi on behalf of the - International Neonatal Immunotherapy Study (INIS)

22Barriers to participation in randomised
controlled trials a systematic review.Ross et
al 1999
- Clinician barriers included
- time constraints
- lack of staff and training
- worry about the impact on the doctor-patient
relationship - concern for patients
- loss of professional autonomy
- difficulty with the consent procedure
- lack of rewards and recognition
- insufficiently interesting question.
23- Patient barriers included
-
- additional demands of the trial
- patient preferences
- worry caused by uncertainty
- concerns about information and consent.
24- There is no evidence on the impact of Digital
Video Decoders (DVDs) or videos on knowledge or
confidence of staff in obtaining consent, and on
uptake of consent by parents. - We explored the effectiveness of a DVD/ video and
accompanying booklet in 24 INIS sites in - describing consent delivery methods
- improving knowledge about the INIS trial.
25VINIS Video/ DVD Booklet site intervention
study
- A pilot RCT in 24 ANZ INIS sites to explore
- whether a video and booklet for staff who seek
consent can improve their knowledge and
confidence - its potential effect on recruitment rate.

26Data Collection issues
- Excellent rate of completion and accuracy of CRFs
- Consent forms
- Please ensure that all signatures by parents and
investigators and witnesses are complete - HIC consent forms
- Please remember to ask new and old parents to
complete this consent form (for economic
analysis) - Days of respiratory support after INIS
intervention - Please include all days the baby received any
respiratory support in your hospital
