Summary of recent, international neurodevelopmental follow‐up studies of extremely premature infants
| Author, Journal, Year | Report type | Population | Locale | Principal findings |
|---|---|---|---|---|
| Joseph, | 10 year neurocognitive and academic evaluation, births 2002–2004 | 23–27 weeks GA | ELGAN Study, USA | >50% exhibited moderate‐to‐severe neurocognitive and academic deficits, with the most extensive impairments at 23–24 weeks GA |
| Serenius, | NDI rates compared at 2.5 and 6.5 years in the same cohort, births 2004–2007 | 22–26 weeks GA | Swedish EXPRESS group | 36% free of NDI. 47% remained in the same NDI category at 6.5 years, 21% moved to a better, 32% to a worse category. 96%, 79%, and 63% of 22‐, 23‐ and 24‐week infants either died or had moderate‐to‐severe NDI. |
| Younge, | Survival and NDI comparing three epochs, births 2000–2003, 2004–2007, 2008–2011 | 22–24 weeks GA | Neonatal Research Network, USA | Survival without NDI improved from 16% in Epoch 1 to 20% in Epoch 3. <1% and 1% of 22‐week infants survived without NDI in Epochs 1 and 3. 7% and 13% of 23‐week infants survived without NDI in Epochs 1 and 3 |
| Cheong, | IQ, academic achievement, neurosensory assessment comparison births 1991–92 vs. 1997 vs. 2005 | <28 weeks GA | Victoria, Australia | Major neurosensory impairment rates have not improved across 3 eras, academic performance deteriorated in the latest cohort. |
| Linsell, | Long term, prospective, population‐based, cohort study, births 1995 | <26 weeks GA | United Kingdom and Ireland | No evidence of improvement in impaired cognitive function in premature infants through 19 years of age. |
| Synnes, | 21 month corrected age neurologic assessment, births 2009 to 2011 | <29 weeks GA | Canadian Neonatal Network | 63%, 62% and 52% of surviving 23‐, 24‐ and 25‐week infants had NDI |
| Twilhaar, | Meta‐analysis and meta‐regression of cognitive outcome reports, births 1990–2008 | <32 weeks GA or <1500 g BWT | All publications, all languages in North America and Europe | 13 point mean overall IQ deficit shown in premature infants compared to term infants. No evidence of improvement over time in this significant cognitive impairment |
| Brydges, | Meta‐analysis of cognitive outcome reports | <32 weeks | All publications in English | Significantly lower IQ, executive functioning, and processing speed in premature infants compared to full‐term infants, and worsens with lower GA and BWT. |
| Adams‐Chapman, | Full spectrum neurologic evaluation, births 2011–2015 | </= 27 weeks GA | Neonatal Research Network, USA | Rate of NDI (BSID III < 85) did not improve over time period (34% vs. 31%). |
| Spittle, | Motor impairment comparison, births 1991–1992 vs. 1997 vs. 2005 | <28 weeks GA < 1000 g BWT | Victoria, Australia | Increasing motor impairment rate across the 3 eras, 23% to 26% to 37% |
| Burnett, | Executive functioning comparison, births 1991–1992 vs. 1997 vs. 2005 | <28 weeks GA < 1000 g | Victoria, Australia | Worse executive function scores in premature infants compared to controls in all 3 eras, most notable in the latest cohort |
| Nakanishi, | Full spectrum neurologic evaluation trend, births 2003–2012 | 22–24 weeks GA | Japan | No improvement in cognitive impairment rates over ten years in surviving 22‐ to 24‐week infants (35%–40%), and an increase noted in CP over the most recent 5 years |
| Inoue, | Full spectrum neurologic evaluation trend, births 2003–2012 | </= 500 g BWT | Japan | No improvement in neurodevelopmental outcomes over 10 years. 60% of survivors were neurologically impaired. |
| Ding, | Meta‐analysis of survival and neurodevelopmental outcomes, births 2005–2016 | 22–25 weeks GA | All English language publications with a minimum 4–10 years follow‐up | Moderate‐to‐severe NDI in survivors was 42%, 41%, 32%, and 23% at 22, 23, 24 and 25 weeks |

Hirschberger, See related Joseph report above | 10 year comprehensive neurodevelopmental burden assessment of infants, births 2002–2004 | 23–27 weeks | ELGAN Study, USA | 52% of 23‐ to 24‐week survivors had at least one significant neurologic impairment (low IQ/EF score, CP, autism, seizures), 26% had two or more deficits |
| Myrhaug, | Meta‐analysis of survival and neurologic impairment, births 2000–2017 | 22–27 weeks GA | All publications in English, German, French or a Scandinavian language | Moderate‐to‐severe NDI in survivors was 60%, 50%, 40% and 30% at 22, 23, 24 and 25 weeks. Risk of NDI was not reduced for children born in the most recent years |
| Rysavy, | Survival and NDI, births 2006–2011 | 22–26 weeks GA | Neonatal Research Network, USA | Survival without moderate‐to‐severe NDI was 9%, 16%, 31%, 45% and 59% at 22, 23, 24, 25 and 26 weeks |
| Brumbaugh, | Survival and NDI, births 2008–2016 | <400 g BWT | Neonatal Research Network, USA | Only 23 of 90 actively treated infants survived, 19 were evaluated, 14/19 (74%) had moderate‐to‐severe NDI |
| Watkins, | Survival and NDI, births 2006–2015 | 22–25 weeks GA | University of Iowa, USA | Centre that advocates near‐universal NICU care <25 weeks: 27% of surviving evaluated infants had moderate‐to‐severe NDI. 36% of surviving 22‐ to 23‐week infants had moderate‐to‐severe NDI. No improvement over time noted |
| O’Reilly, | Comprehensive neuro‐psychological evaluation at 19 years, births 1995 | <26 weeks GA | United Kingdom and Ireland | 45% of survivors had major full scale IQ impairments at 19 years of age, a rate 15 times higher than term controls |
| Franz, | Survival and NDI, births 2011–2014 | 400–999 g BWT | European collaboration | 44% of actively managed infants either died or had NDI. 36% of survivors had significant cognitive impairment |
