Two-year neurodevelopmental data for preterm infants born over an 11-year period in England and Wales, 2008-2018: a retrospective study using the National Neonatal Research Database.

OBJECTIVE: United Kingdom guidelines recommend all infants born <30 weeks' gestation receive neurodevelopmental follow-up at 2 years corrected age. In this study, we describe completeness and results of 2-year neurodevelopmental records in the National Neonatal Research Database (NNRD). DESIGN: This retrospective cohort study uses data from the NNRD, which holds data on all neonatal admissions in England and Wales, including 2year follow-up status. PATIENTS: We included all preterm infants born <30 weeks' gestation between 1 January 2008 and 31 December 2018 in England and Wales, who survived to discharge from neonatal care. MAIN OUTCOME MEASURES: Presence of a 2-year neurodevelopmental assessment record in the NNRD, use of standardised assessment tools, results of functional 2-year neurodevelopmental assessments (visual, auditory, neuromotor, communication, overall development). RESULTS: Of the 41 505 infants included, 24 125 (58%) had a 2-year neurodevelopmental assessment recorded. This improved over time, from 32% to 71% for births in 2008 and 2018, respectively.Of those with available data: 0.4% were blind; 1% had a hearing impairment not correctable with aids; 13% had <5 meaningful words, vocalisations or signs; 8% could not walk without assistance and 9% had severe (≥12 months) developmental delay. CONCLUSIONS: The proportion of infants admitted to neonatal units in England and Wales with a 2-year neurodevelopmental record has improved over time. Rates of follow-up data from recent years are comparable to those of bespoke observational studies. With continual improvement in data completeness, the potential for use of NNRD as a source of longer-term outcome data can be realised.

Effect of national guidance on survival for babies born at 22 weeks' gestation in England and Wales: population based cohort study.

Objectives: To explore the effect of changes in national clinical recommendations in 2019 that extended provision of survival focused care to babies born at 22 weeks' gestation in England and Wales. Design: Population based cohort study. Setting: England and Wales, comprising routine data for births and hospital records. Participants: Babies alive at the onset of care in labour at 22 weeks+0 days to 22 weeks+6 days and at 23 weeks+0 days to 24 weeks+6 days for comparison purposes between 1 January 2018 and 31 December 2021. Main outcome measures: Percentage of babies given survival focused care (active respiratory support after birth), admitted to neonatal care, and surviving to discharge in 2018-19 and 2020-21. Results: For the 1001 babies alive at the onset of labour at 22 weeks' gestation, a threefold increase was noted in: survival focused care provision from 11.3% to 38.4% (risk ratio 3.41 (95% confidence interval 2.61 to 4.45)); admissions to neonatal units from 7.4% to 28.1% (3.77 (2.70 to 5.27)), and survival to discharge from neonatal care from 2.5% to 8.2% (3.29 (1.78 to 6.09)). More babies of lower birth weight and early gestational age received survival focused care in 2020-21 than 2018-19 (46% to 64% at <500g weight; 19% to 31% at 22 weeks+0 days to 22 weeks+3 days). Conclusions: A change in national guidance to recommend a risk based approach was associated with a threefold increase in 22 weeks' gestation babies receiving survival focused care. The number of babies being admitted to neonatal units and those surviving to discharge increased.

Views of parents, adults born preterm and professionals on linkage of real-world data of preterm babies.

OBJECTIVE: To explore views of parents of preterm babies, adults born preterm and professionals, on the linkage of real-world health and education data for research on improving future outcomes of babies born preterm. DESIGN: Three-stage mixed-methods participatory design involving focus groups, a national survey and interviews. Survey participants who expressed uncertainty or negative views were sampled purposively for invitation to interview. Mixed methods were used for data analysis. SETTING AND PARTICIPANTS: All data collection was online. Participants were: focus groups-17 parents; survey-499 parents, 44 adults born preterm (total 543); interviews-6 parents, 1 adult born preterm, 3 clinicians, 2 teachers. RESULTS: Three key themes were identified: (1) Data linkage and opt-out consent make sense for improving future outcomes. We found clear demand for better information on long-term outcomes and strong support for data linkage with opt-out consent as a means of achieving this. (2) Information requirements-what, how and when. There was support for providing information in different formats and discussing linkage near to, or following discharge from, the neonatal unit, but not sooner. (3) Looking to the future; the rights of young people. We identified a desire for individuals born preterm to be consulted in the future on the use of their data. CONCLUSION: With appropriate information provision, at the right time, parents, adults born preterm and professionals are supportive of data linkage for research, including where temporary identifiers and opt-out consent are used. Resources are being co-produced to improve communication about routine data linkage.
