Priorities for collaborative research using very preterm birth cohorts

The early educational environment at five years of age in a European cohort of children born very preterm: challenges and opportunities for research

BACKGROUND

Early childhood education offers opportunities for stimulation in multiple developmental domains and its positive impact on long-term outcomes and wellbeing for children is well documented. Few studies have explored early education in children born very preterm (VPT; <32 weeks of gestation) who are at higher risk of neurodevelopmental disorders and poor educational outcomes than their term-born peers. The purpose of the study is to describe and compare the educational environment of children born VPT in European countries at 5 years of age according to the degree of perinatal risk.

METHODS

Data originated from the population-based Screening to Improve Health In very Preterm infants (SHIPS) cohort of children born VPT in 2011/2012 in 19 regions from 11 European countries. Perinatal data were collected from medical records and the 5-year follow-up was conducted using parental questionnaires. Outcomes at 5 years were participation in early education (any, type, intensity of participation) and receipt of special educational support, which were harmonized across countries.

RESULTS

Out of 6,759 eligible children, 3,687 (54.6%) were followed up at 5 years (mean gestational age 29.3 weeks). At 5 years, almost all children (98.6%) were in an educational program, but type (preschool/primary), attendance (full-time/part-time) and use and type of school support/services differed by country. In some countries, children with high perinatal risk were more likely to be in full-time education than those with low risk (e.g. Estonia: 97.9% vs. 87.1%), while the inverse pattern was observed elsewhere (e.g. Poland: 78.5% vs. 92.8%). Overall, 22.8% of children received special educational support (country range: 12.4-34.4%) with more support received by children with higher perinatal risk. Large variations between countries remained after adjustment for socio-demographic characteristics.

CONCLUSIONS

There are marked variations in approaches to early education for children born VPT in Europe, raising opportunities to explore its impact on their neurodevelopment and well-being.

Parenting stress and health-related quality of life among parents of extremely preterm born early adolescents in England: a cross-sectional study

OBJECTIVE

To determine whether extremely preterm (EP) birth exerts persisting effects on parents in early adolescence.

DESIGN

Cross-sectional survey conducted between March 2017 and October 2018.

SETTING

Evaluation of a longitudinal population-based birth cohort in England at 11 years of age (EPICure2@11 Study).

PARTICIPANTS

Parents of EP (<27 weeks of gestation) adolescents and control parents of term born (≥37 weeks of gestation) classmates of similar age and sex.

MAIN OUTCOME MEASURES

The Parenting Stress Index Short Form (PSI-4-SF) and the Short Form Health Survey (SF-12v1).

RESULTS

The 163 EP and 125 comparison respondents were most commonly mothers in their mid-40s. EP parents reported higher total parenting stress scores compared with controls, overall (adjusted difference in means: 14 (95% CI 9 to 20)) and after exclusion of moderate and severe child disability and multiples (9 (95% CI 3 to 15). Average physical and mental health-related quality of life scores were similar in the two groups (adjusted difference in means physical health: -2 (95% CI -4 to 1) and mental health: -1 (95% CI -4 to 1)). Among EP parents, 12% (20/164) reported the combination of high parenting stress and low mental health scores. With increasing child age, parenting stress scores for preterm parents were lower in contrast to controls who reported increasing parenting stress.

CONCLUSIONS

In early adolescence, compared with parents of term-born children, EP parents experience increased levels of parenting stress that are particularly high among a proportion of parents and associated with lower mental health-related quality of life. Practitioner awareness of this continuing risk throughout childhood is important to support parental abilities and well-being.

Childhood outcomes after low-grade intraventricular haemorrhage: A systematic review and meta-analysis

AIM

To undertake a systematic review and meta-analysis exploring school-age neurodevelopmental outcomes of children after low-grade intraventricular haemorrhage (IVH).

METHOD

The published and grey literature was extensively searched to identify observational comparative studies exploring neurodevelopmental outcomes after IVH grades 1 and 2. Our primary outcome was neurodevelopmental impairment after 5 years of age, which included cognitive, motor, speech and language, behavioural, hearing, or visual impairments.

RESULTS

This review included 12 studies and over 2036 infants born preterm with low grade IVH. Studies used 30 different neurodevelopmental tools to determine outcomes. There was conflicting evidence of the composite risk of neurodevelopmental impairment after low-grade IVH. There was evidence of an association between low-grade IVH and lower IQ at school age (-4.23, 95% confidence interval [CI] -7.53, -0.92, I2  = 0%) but impact on school performance was unclear. Studies reported an increased crude risk of cerebral palsy after low-grade IVH (odds ratio [OR] 2.92, 95% CI 1.95, 4.37, I2  = 41%). No increased risk of speech and language impairment or behavioural impairment was found. Few studies addressed hearing and visual impairment.

INTERPRETATION

This systematic review presents evidence that low-grade IVH is associated with specific neurodevelopmental impairments at school age, lending support to the theory that low-grade IVH is not a benign condition.

WHAT THIS PAPER ADDS

The functional impact of low-grade intraventricular haemorrhage (IVH) at school age is unknown. Low-grade IVH is associated with a lower IQ at school age. The risk of cerebral palsy is increased after low-grade IVH. Low-grade IVH is not associated with speech and language impairment.

Differences in the attitudes towards resuscitation of extremely premature infants between neonatologists and obstetricians: a survey study in China

Objectives

Neonatologists and obstetricians are crucial decision-makers regarding the resuscitation of extremely preterm infants (EPIs). However, there is a scarcity of research regarding the differing perspectives on EPI resuscitation between these medical professionals. We aim to determine the differences and influential factors of their attitudes towards EPIs resuscitation in China.

Methods

This cross-sectional study was conducted in public hospitals of 31 provinces in Chinese mainland from June to July 2021. Influential factors of binary variables and those of ordinal variables were analyzed by modified Poisson regression models and multinomial logistic regression models due to the invalid parallel line assumption of ordinal logistic regression models.

Results

A total of 832 neonatologists and 1,478 obstetricians who were deputy chief physicians or chief physicians participated. Compared with obstetricians, neonatologists delivered a larger proportion of infants of <28-week gestational age (87.74% vs. 84.91%) and were inclined to think it inappropriate to use 28 weeks as the cutoff of gestational age for providing full care to premature infants [63.34% vs. 31.60%, adjusted prevalence ratio = 1.61 (95% CI: 1.46-1.77)], and to suggest smaller cutoffs of gestational age and birth weight for providing EPIs resuscitation. Notably, 46.49% of the neonatologists and 19.01% of the obstetricians believed infants ≤24 weeks' gestation should receive resuscitation.

Conclusions

In China, notable disparities exist in attitudes of neonatologists and obstetricians towards resuscitating EPIs. Strengthening collaboration between these two groups and revising the pertinent guidelines as soon as possible would be instrumental in elevating the resuscitation rate of EPIs.

Parental Experiences of Neonatal Care: A Nationwide Study on Determinants of Excellence

INTRODUCTION

Infant- and family-centered developmental care can reduce adverse outcomes in both infants and parents. Parents' experiences of the care and staff treatment remain to be evaluated.

METHODS

Parents of infants admitted to neonatal units in Sweden from July 2020 to May 2022 responded to a questionnaire with standardized questions about in-hospital care. Exposures were hospital, gestational age, length of hospital stay, unit level, and bed density. The proportions of parents rating aspects of neonatal care as excellent, defined as five on a Likert scale, and the determinants of excellence were described. The results were benchmarked with ratings in adult somatic care.

RESULTS

A total of 4,475/13,108 (34%) parents responded. The ratings of excellent care varied by question from 65% to 90%. The largest variation in excellence between neonatal units (range 43-80%) was found for "participation and involvement." The proportion of excellence was significantly lower among parents of extremely preterm infants. Confidence in the staff was lower in parents of extremely preterm infants than in parents of term infants (56% vs. 83%). Longer hospital stays affected the experience of neonatal care adversely, whereas level of care and bed density were overall unrelated to the parental experience. Parents in neonatal care rated the care as excellent to a higher extent than patients cared for in adult medicine.

CONCLUSION

A majority of parents rated neonatal care in Sweden as excellent. The less frequent ratings of excellence among parents of extremely preterm infants indicate that more could be done to optimize parental involvement and support.

Using Digital Tools to Study the Health of Adults Born Preterm at a Large Scale: e-Cohort Pilot Study

BACKGROUND

Preterm birth is a global health concern. Its adverse consequences may persist throughout the life course, exerting a potentially heavy burden on families, health systems, and societies. In high-income countries, the first children who benefited from improved care are now adults entering middle age. However, there is a clear gap in the knowledge regarding the long-term outcomes of individuals born preterm.

OBJECTIVE

This study aimed to assess the feasibility of recruiting and following up an e-cohort of adults born preterm worldwide and provide estimations of participation, characteristics of participants, the acceptability of questions, and the quality of data collected.

METHODS

We implemented a prospective, open, observational, and international e-cohort pilot study (Health of Adult People Born Preterm-an e-Cohort Pilot Study [HAPP-e]). Inclusion criteria were being an adult (aged ≥18 years), born preterm (<37 weeks of gestation), having internet access and an email address, and understanding at least 1 of the available languages. A large, multifaceted, and multilingual communication strategy was established. Between December 2019 and June 2021, inclusion and repeated data collection were performed using a secured web platform. We provided descriptive statistics regarding participation in the e-cohort, namely, the number of persons who registered on the platform, signed the consent form, initiated and completed the baseline questionnaire, and initiated and completed the follow-up questionnaire. We also described the main characteristics of the HAPP-e participants and provided an assessment of the quality of the data and the acceptability of sensitive questions.

RESULTS

As of December 31, 2020, a total of 1004 persons had registered on the platform, leading to 527 accounts with a confirmed email and 333 signed consent forms. A total of 333 participants initiated the baseline questionnaire. All participants were invited to follow-up, and 35.7% (119/333) consented to participate, of whom 97.5% (116/119) initiated the follow-up questionnaire. Completion rates were very high both at baseline (296/333, 88.9%) and at follow-up (112/116, 96.6%). This sample of adults born preterm in 34 countries covered a wide range of sociodemographic and health characteristics. The gestational age at birth ranged from 23+6 to 36+6 weeks (median 32, IQR 29-35 weeks). Only 2.1% (7/333) of the participants had previously participated in a cohort of individuals born preterm. Women (252/333, 75.7%) and highly educated participants (235/327, 71.9%) were also overrepresented. Good quality data were collected thanks to validation controls implemented on the web platform. The acceptability of potentially sensitive questions was excellent, as very few participants chose the "I prefer not to say" option when available.

CONCLUSIONS

Although we identified room for improvement in specific procedures, this pilot study confirmed the great potential for recruiting a large and diverse sample of adults born preterm worldwide, thereby advancing research on adults born preterm.

Life course of retrospective harmonization initiatives: key elements to consider

Optimizing research on the developmental origins of health and disease (DOHaD) involves implementing initiatives maximizing the use of the available cohort study data; achieving sufficient statistical power to support subgroup analysis; and using participant data presenting adequate follow-up and exposure heterogeneity. It also involves being able to undertake comparison, cross-validation, or replication across data sets. To answer these requirements, cohort study data need to be findable, accessible, interoperable, and reusable (FAIR), and more particularly, it often needs to be harmonized. Harmonization is required to achieve or improve comparability of the putatively equivalent measures collected by different studies on different individuals. Although the characteristics of the research initiatives generating and using harmonized data vary extensively, all are confronted by similar issues. Having to collate, understand, process, host, and co-analyze data from individual cohort studies is particularly challenging. The scientific success and timely management of projects can be facilitated by an ensemble of factors. The current document provides an overview of the 'life course' of research projects requiring harmonization of existing data and highlights key elements to be considered from the inception to the end of the project.

Risk factors for cerebral palsy and movement difficulties in 5-year-old children born extremely preterm

BACKGROUND

Motor impairment is common after extremely preterm (EPT, <28 weeks' gestational age (GA)) birth, with cerebral palsy (CP) affecting about 10% of children and non-CP movement difficulties (MD) up to 50%. This study investigated the sociodemographic, perinatal and neonatal risk factors for CP and non-CP MD.

METHODS

Data come from a European population-based cohort of children born EPT in 2011-2012 in 11 countries. We used multinomial logistic regression to assess risk factors for CP and non-CP MD (Movement Assessment Battery for Children - 2nd edition ≤5th percentile) compared to no MD (>15th percentile) among 5-year-old children.

RESULTS

Compared to children without MD (n = 366), young maternal age, male sex and bronchopulmonary dysplasia were similarly associated with CP (n = 100) and non-CP MD (n = 224) with relative risk ratios (RRR) ranging from 2.3 to 3.6. CP was strongly related to severe brain lesions (RRR >10), other neonatal morbidities, congenital anomalies and low Apgar score (RRR: 2.4-3.3), while non-CP MD was associated with primiparity, maternal education, small for GA (RRR: 1.6-2.6) and severe brain lesions, but at a much lower order of magnitude.

CONCLUSION

CP and non-CP MD have different risk factor profiles, with fewer clinical but more sociodemographic risk factors for non-CP MD.

IMPACT

Young maternal age, male sex and bronchopulmonary dysplasia similarly increased risks of both cerebral palsy and non-cerebral palsy movement difficulties. Cerebral palsy was strongly related to clinical risk factors including severe brain lesions and other neonatal morbidities, while non-cerebral palsy movement difficulties were more associated with sociodemographic risk factors. These results on the similarities and differences in risk profiles of children with cerebral palsy and non-cerebral palsy movement difficulties raise questions for etiological research and provide a basis for improving the identification of children who may benefit from follow-up and early intervention.

Research priorities for maternal and perinatal health clinical trials and methods used to identify them: A systematic review

OBJECTIVE

Research prioritisation helps to target research resources to the most pressing health and healthcare needs of a population. This systematic review aimed to report research priorities in maternal and perinatal health and to assess the methods that were used to identify them.

METHODS

A systematic review was undertaken. Projects that aimed to identify research priorities that were considered to be amenable to clinical trials research were eligible for inclusion. The search, limited to the last decade and publications in English, included MEDLINE, EMBASE, CINHAL, relevant Cochrane priority lists, Cochrane Priority Setting Methods Group homepage, James Lind Alliance homepage, Joanna Brigg's register, PROSPERO register, reference lists of all included articles, grey literature, and the websites of relevant professional bodies, until 13 October 2020. The methods used for prioritisation were appraised using the Reporting Guideline for Priority Setting of Health Research (REPRISE).

FINDINGS

From the 62 included projects, 757 research priorities of relevance to maternal and perinatal health were identified. The most common priorities related to healthcare systems and services, pregnancy care and complications, and newborn care and complications. The least common priorities related to preconception and postpartum health, maternal mental health, contraception and pregnancy termination, and fetal medicine and surveillance. The most commonly used prioritisation methods were Delphi (20, 32%), Child Health Nutrition Research Initiative (17, 27%) and the James Lind Alliance (10, 16%). The fourteen projects (23%) that reported on at least 80% of the items included in the REPRISE guideline all used an established research prioritisation method.

CONCLUSIONS

There are a large number of diverse research priorities in maternal and perinatal health that are amenable to future clinical trials research. These have been identified by a variety of research prioritisation methods.

Survey of data collection methods and retention strategies in European birth cohorts of children and adults born very preterm

BACKGROUND

The long-term follow-up of very preterm and very low birthweight cohorts contributes to valuable evidence to understand life-course outcomes in these vulnerable populations. However, attrition is a major challenge in long-term outcome studies. Examining the techniques used by existing cohorts may help to reveal practices that enhance willingness to continue participation over time.

OBJECTIVES

To evaluate the effect of data collection methods and retention strategies on overall retention in European birth cohorts of individuals born very preterm and very low birthweight.

METHODS

A survey of European cohorts integrated in the RECAP-preterm Consortium provided data on study characteristics, retention at the most recent follow-up, data collection methods and retention strategies. Cohorts were classified according to participants' age at most recent follow-up as child (<18) or adult cohorts (≥18 years old).

RESULTS

Data were obtained for 17 (81%) cohorts (7 adult and 10 child) in 12 countries. Considering the baseline, at the most recent follow-up, overall retention ranged from 10% to 99%. Child cohorts presented higher median retention (68% versus 38% or 52% for adult cohorts with ≤5 or >5 follow-ups) and used relatively more retention strategies. For contact and invitation, cohorts mostly resorted to invitation letters, and to face-to-face interviews for assessments. Study duration was negatively correlated with retention and positively associated with the number of follow-up evaluation. We identified 109 retention strategies, with a median of 6 per cohort; bond-building (n = 41; 38%) was the most utilised, followed by barrier-reduction (n = 36; 33%) and reminders (n = 32; 29%). Retention was not influenced by category or number of strategies.

CONCLUSIONS

Regular contact with cohort participants favour retention whilst neither the number nor the categories of retention strategies used seemed to have an influence, suggesting that tailored strategies focussed on participants at higher risk of dropout might be a more effective approach.

Machine learning methods to predict attrition in a population-based cohort of very preterm infants

The timely identification of cohort participants at higher risk for attrition is important to earlier interventions and efficient use of research resources. Machine learning may have advantages over the conventional approaches to improve discrimination by analysing complex interactions among predictors. We developed predictive models of attrition applying a conventional regression model and different machine learning methods. A total of 542 very preterm (< 32 gestational weeks) infants born in Portugal as part of the European Effective Perinatal Intensive Care in Europe (EPICE) cohort were included. We tested a model with a fixed number of predictors (Baseline) and a second with a dynamic number of variables added from each follow-up (Incremental). Eight classification methods were applied: AdaBoost, Artificial Neural Networks, Functional Trees, J48, J48Consolidated, K-Nearest Neighbours, Random Forest and Logistic Regression. Performance was compared using AUC- PR (Area Under the Curve—Precision Recall), Accuracy, Sensitivity and F-measure. Attrition at the four follow-ups were, respectively: 16%, 25%, 13% and 17%. Both models demonstrated good predictive performance, AUC-PR ranging between 69 and 94.1 in Baseline and from 72.5 to 97.1 in Incremental model. Of the whole set of methods, Random Forest presented the best performance at all follow-ups [AUC-PR₁: 94.1 (2.0); AUC-PR₂: 91.2 (1.2); AUC-PR₃: 97.1 (1.0); AUC-PR₄: 96.5 (1.7)]. Logistic Regression performed well below Random Forest. The top-ranked predictors were common for both models in all follow-ups: birthweight, gestational age, maternal age, and length of hospital stay. Random Forest presented the highest capacity for prediction and provided interpretable predictors. Researchers involved in cohorts can benefit from our robust models to prepare for and prevent loss to follow-up by directing efforts toward individuals at higher risk.

The continuing evolution of birth cohort studies: achievements and challenges

Well-designed birth cohorts are able to estimate prevalence/distribution of various health events/outcomes, and to link early-life origins with adult health and function. The past two decades have seen a surge in the establishment of new birth cohorts and their accompanying research. We discussed distinct designs of current birth cohort studies, reviewed their achievements, and highlighted insights obtained from birth cohort studies, as well as challenges we are facing. Birth cohort studies are providing increasing opportunities to identify determining factors for short- and long-term health, yielding substantial evidence to uncover biological mechanisms of diseases and phenotypes, and providing further insights for public health. Dynamic monitoring, accurate measurements, long-term follow-ups and collaborative efforts are warranted in new birth cohorts to elucidate the nature of life course relationships in contemporary generation.

Movement Difficulties at Age Five Among Extremely Preterm Infants

BACKGROUND AND OBJECTIVES

Children born extremely preterm (EPT), <28 weeks' gestational age, face higher risks of movement difficulties than their term-born peers. Studies report varying prevalence estimates and prognostic factors identifying children who could benefit from early intervention are inconsistent. This study investigated the prevalence of movement difficulties in children born EPT and associated risk factors.

METHODS

Data come from a population-based EPT birth cohort in 2011 and 2012 in 11 European countries. Children without cerebral palsy were assessed at 5 years of age (N = 772) with the Movement Assessment Battery for Children-Second Edition, which classifies movement difficulties as none (>15th percentile), at risk (6th-15th percentile) and significant (≤5th percentile). Associations with sociodemographic, perinatal, and neonatal characteristics collected from obstetric and neonatal medical records and parental questionnaires were estimated using multinomial logistic regression.

RESULTS

We found 23.2% (n = 179) of children were at risk for movement difficulties and 31.7% (n = 244) had significant movement difficulties. Lower gestational age, severe brain lesions, and receipt of postnatal corticosteroids were associated with significant movement difficulties, whereas male sex and bronchopulmonary dysplasia were associated with being at risk and having significant movement difficulties. Children with younger, primiparous, less educated, and non-European-born mothers were more likely to have significant movement difficulties. Differences in prevalence between countries remained after population case-mix adjustments.

CONCLUSIONS

This study confirms a high prevalence of movement difficulties among EPT children without cerebral palsy, which are associated with perinatal and neonatal risk factors as well as sociodemographic characteristics and country.

Maternal education and cognitive development in 15 European very-preterm birth cohorts from the RECAP Preterm platform

BACKGROUND

Studies are sparse and inconclusive about the association between maternal education and cognitive development among children born very preterm (VPT). Although this association is well established in the general population, questions remain about its magnitude among children born VPT whose risks of medical and developmental complications are high. We investigated the association of maternal education with cognitive outcomes in European VPT birth cohorts.

METHODS

We used harmonized aggregated data from 15 population-based cohorts of children born at <32 weeks of gestational age (GA) or <1500 g from 1985 to 2013 in 13 countries with information on maternal education and assessments of general development at 2-3 years and/or intelligence quotients between 4 and 15 years. Term-born controls (≥37 weeks of GA) were available in eight cohorts. Maternal education was classified as: low (primary/lower secondary); medium (upper secondary/short tertiary); high (bachelor's/higher). Pooled standardized mean differences (SMDs) in cognitive scores were estimated (reference: high educational level) for children assessed at ages 2-3, 4-7 and 8-15 years.

RESULTS

The study included 10 145 VPT children from 12 cohorts at 2-3 years, 8829 from 12 cohorts at 4-7 years and 1865 children from 6 cohorts at 8-15 years. Children whose mothers had low, compared with high, educational attainment scored lower on cognitive measures [pooled unadjusted SMDs: 2-3 years = -0.32 (95% confidence intervals: -0.43 to -0.21); 4-7 years = -0.57 (-0.67; -0.47); 8-15 years = -0.54 (-0.72; -0.37)]. Analyses by GA subgroups (<27 vs ≥27 weeks) in children without severe neonatal morbidity and term controls yielded similar results.

CONCLUSIONS

Across diverse settings and regardless of the degree of prematurity, low maternal education was associated with lower cognition.

Birth outcomes between 22 and 26 weeks' gestation in national population-based cohorts from Sweden, England and France

AIM

We investigated the timing of survival differences and effects on morbidity for foetuses alive at maternal admission to hospital delivered at 22 to 26 weeks' gestational age (GA).

METHODS

Data from the EXPRESS (Sweden, 2004-07), EPICure-2 (England, 2006) and EPIPAGE-2 (France, 2011) cohorts were harmonised. Survival, stratified by GA, was analysed to 112 days using Kaplan-Meier analyses and Cox regression adjusted for population and pregnancy characteristics; neonatal morbidities, survival to discharge and follow-up and outcomes at 2-3 years of age were compared.

RESULTS

Among 769 EXPRESS, 2310 EPICure-2 and 1359 EPIPAGE-2 foetuses, 112-day survival was, respectively, 28.2%, 10.8% and 0.5% at 22-23 weeks' GA; 68.5%, 40.0% and 23.6% at 24 weeks; 80.5%, 64.8% and 56.9% at 25 weeks; and 86.6%, 77.1% and 74.4% at 26 weeks. Deaths were most marked in EPIPAGE-2 before 1 day at 22-23 and 24 weeks GA. At 25 weeks, survival varied before 28 days; differences at 26 weeks were minimal. Cox analyses were consistent with the Kaplan-Meier analyses. Variations in morbidities were not clearly associated with survival.

CONCLUSION

Differences in survival and morbidity outcomes for extremely preterm births are evident despite adjustment for background characteristics. No clear relationship was identified between early mortality and later patterns of morbidity.

Identifying research priorities in newborn medicine: a Delphi study of parents' views

OBJECTIVE

Neonatal conditions can have lifelong implications for the health and well-being of children and families. Traditionally, parents and patients have not been included in shaping the agenda for research and yet they are profoundly affected by the neonatal experience and its consequences. This study aimed to identify consensus research priorities among parents/patients of newborn medicine in Australia and New Zealand.

DESIGN

Parents/patients with experience of neonatal care in Australia and New Zealand completed an online Delphi study to identify research priorities across four epochs (neonatal admission, early childhood, childhood/adolescence and adulthood). Parents/patients first generated key challenges in each of these epochs. Through inductive thematic analysis, recurring topics were identified and research questions generated. Parents/patients rated these questions in terms of priorities and a list of questions consistently rated as high priority was identified.

PARTICIPANTS

393 individuals participated, 388 parents whose children had received neonatal care and 5 adults who had received neonatal care themselves.

RESULTS

Many research questions were identified as high-priority across the lifespan. These included how to best support parental mental health, relationships between parents and neonatal clinical staff (including involvement in care and communication), bonding and the parent-child relationship, improving neonatal medical care and addressing long-term impacts on child health and neurodevelopment.

CONCLUSIONS

Parents with experience of newborn medicine have strong, clear and recurring research priorities spanning neonatal care practices, psychological and other impacts on families, and impacts on child development. These findings should guide neonatal research efforts. In addition to generating new knowledge, improved translation of existing evidence to parents is also needed.

Parent priorities for research and communication concerning childhood outcomes following preterm birth

Background: Children born preterm (before 37 weeks of gestation) are at risk for several adverse childhood outcomes. Parent priorities for research into these outcomes, and preferences for receiving information about these risks, have not previously been established. Here we report the results of an online survey designed to understand parent priorities for research and their preferences for receiving information about childhood outcomes. Methods: An online survey was circulated through social media and was completed by 148 parents of preterm children between the ages of 0 and 12 years from around the United Kingdom (UK). Survey questions were in the form of rating scale, multiple choice, ranking or open-ended free text questions. Descriptive analysis was applied to the quantitative data. Illustrative quotes were extracted from the qualitative free text data and a subset of these questions were analysed using framework analysis. Results: Parent priorities for research centre around identification of factors which can protect against or improve adverse cognitive or developmental outcomes. The majority of parents would prefer for communication to begin within the first year of the child's life. Parents reported a knowledge gap among health visitors, early years educators and schools. Conclusions: In order to align with parent preferences, research should prioritise identification of protective factors and the development of effective interventions to improve outcomes. Training for health visitors and educational professionals could improve the experiences of families and children.

Teachers' knowledge and approaches to supporting preterm children in the classroom

BACKGROUND & AIMS

Teachers in the UK receive little training about the long-term consequences of preterm birth on children's development. Our aim was to assess knowledge and elicit suggestions for improving educational practice in the US by means of a mixed-method study.

METHODS

246 US teachers (92.7% female) completed the validated Preterm Birth - Knowledge Scale (PB-KS). Of the participating teachers, 50.9% reported professional experience with preterm born children. A representative subsample of 35 teachers responded to a case vignette by describing how they would support the child in the classroom. Answers were coded using thematic content analysis.

RESULTS

Overall, the mean PB-KS score was 15.21 (SD = 5.31). Participating teachers who had professional experience with a preterm child had higher mean PB-KS scores than teachers without (16.95 vs. 15.24, p = .012). Qualitative responses provided specific content for classroom intervention.

CONCLUSIONS

Our findings show that US teachers have limited knowledge of the long-term impact of preterm birth. They provided important indicators for the design of targeted classroom interventions to support the learning of preterm children.

4441 children aged 5½ born at 24-26, 27-31, and 32-34 weeks MAIN OUTCOME MEASURES: Severe/moderate neurodevelopmental disabilities, defined as severe/moderate cerebral palsy (Gross Motor Function Classification System (GMFCS) ≥2), or unilateral or bilateral blindness or deafness, or full scale intelligence quotient less than minus two standard deviations (Wechsler Preschool and Primary Scale of Intelligence, 4th edition). Mild neurodevelopmental disabilities, defined as mild cerebral palsy (GMFCS-1), or visual disability ≥3.2/10 and <5/10, or hearing loss <40 dB, or full scale intelligence quotient (minus two to minus one standard deviation) or developmental coordination disorders (Movement Assessment Battery for Children, 2nd edition, total score less than or equal to the fifth centile), or behavioural difficulties (strengths and difficulties questionnaire, total score greater than or equal to the 90th centile), school assistance (mainstream class with support or special school), complex developmental interventions, and parents' concerns about development. The distributions of the scores in contemporary term born children were used as reference. Results are given after multiple imputation as percentages of outcome measures with exact binomial 95% confidence intervals.

RESULTS

Among 4441 participants, 3083 (69.4%) children were assessed. Rates of severe/moderate neurodevelopmental disabilities were 28% (95% confidence interval 23.4% to 32.2%), 19% (16.8% to 20.7%), and 12% (9.2% to 14.0%) and of mild disabilities were 38.5% (33.7% to 43.4%), 36% (33.4% to 38.1%), and 34% (30.2% to 37.4%) at 24-26, 27-31, and 32-34 weeks, respectively. Assistance at school was used by 27% (22.9% to 31.7%), 14% (12.1% to 15.9%), and 7% (4.4% to 9.0%) of children at 24-26, 27-31, and 32-34 weeks, respectively. About half of the children born at 24-26 weeks (52% (46.4% to 57.3%)) received at least one developmental intervention which decreased to 26% (21.8% to 29.4%) for those born at 32-34 weeks. Behaviour was the concern most commonly reported by parents. Rates of neurodevelopment disabilities increased as gestational age decreased and were higher in families with low socioeconomic status.

CONCLUSIONS

In this large cohort of children born preterm, rates of severe/moderate neurodevelopmental disabilities remained high in each gestational age group. Proportions of children receiving school assistance or complex developmental interventions might have a significant impact on educational and health organisations. Parental concerns about behaviour warrant attention.
