• Created from routine electronic patient records 

• Used for multiple purposes including audit, evaluation, and research

• Data should be recorded once, and well

• Data should be quality assured

• Parents, healthcare professionals and policy‐makers should be involved in developing the wider secondary uses of healthcare data

Confounding

Data may be unreliable

Costly and time consuming 

Research protocol not the same as routine care

Findings may have limited generalisability 

Data are recorded for specific trial purposes

Strong internal validity 

Real world care

Findings more generalisable

Cheaper, faster

• Power to detect a clinically relevant reduction in severe NEC (surgery and/or death), e.g. from 4% to 2.5%  requires 2325 per group (90% power, α=0.05)

• The largest trial involving preterm infants, INIS, recruited 3493 participants, involved 113 hospitals in 9 countries,took 6 years and cost > £1m

• There are about 4200 <30w gestation babies born in the  UK annually

• Together we could answer important questions about newborn care quickly and at lower cost
