Premature babies are a third less likely to die if they are born in the biggest specialist centres, according to analysis that will intensify calls for more centralisation of maternity care.
Mothers at risk of giving birth early have been urged to consider shunning their local hospital in favour of one with a busy neonatal unit after researchers found that centres which saw the most preterm babies tended to be safest.
They looked at data on 20,554 babies born before 33 weeks from 165 neonatal units in English hospitals, of whom 789 died. The researchers said in the journal BMJ Open that premature babies were 30 per cent less likely to die in the quarter of units that included the biggest.
“This is one of the arguments in favour of centralising specialist services,” the senior author, Neena Modi, from Imperial College London, said. She added that this did not mean “axing all smaller hospitals”, but arranging for low-risk women to give birth locally while those with complications could be taken quickly to specialist centres.
“The lesson for mums is that if you are considered to be at risk of delivering prematurely, you don’t want necessarily to go to the closest hospital,” she said.

|Weeks of pregnancy, or birth weight||Number of infants who had problems later on|
|Weight less than 1000 g (2 lb)||Up to 4 out of 10 had one or more moderate or severe problems by the time they were age 8.3 These problems included intellectual disability, cerebral palsy, blindness, and deafness.|
|23 to 25 weeks||At age 2½, about 3 out of 10 had one or more of the severe problems listed above.4 This means that about 7 out of 10 did not get these problems. At age 6, about 5 out of 10 children born at these early ages were more likely than other children to have attention problems, behavior problems, and problems adjusting to school.5|
|25 to 26 weeks||Nearly 4 out of 10 had problems at age 19, including problems with hearing, sight, intellectual disability, and having a job.6 This means that more than 6 out of 10 did not have these problems.|
