RESUMO
BACKGROUND: Children born very preterm (<32 weeks of gestation) face high risks of neurodevelopmental and health difficulties compared with children born at term. Follow-up after discharge from the neonatal intensive care unit is essential to ensure early detection and intervention, but data on policy approaches are sparse. METHODS: We investigated the characteristics of follow-up policy and programmes in 11 European countries from 2011 to 2022 using healthcare informant questionnaires and the published/grey literature. We further explored how one aspect of follow-up, its recommended duration, may be reflected in the percent of parents reporting that their children are receiving follow-up services at 5 years of age in these countries using data from an area-based cohort of very preterm births in 2011/12 (N = 3635). RESULTS: Between 2011/12 and 22, the number of countries with follow-up policies or programmes increased from 6 to 11. The policies and programmes were heterogeneous in eligibility criteria, duration and content. In countries that recommended longer follow-up, parent-reported follow-up rates at 5 years of age were higher, especially among the highest risk children, born <28 weeks' gestation or with birthweight <1000 g: between 42.1% and 70.1%, vs. <20% in most countries without recommendations. CONCLUSIONS: Large variations exist in follow-up policies and programmes for children born very preterm in Europe; differences in recommended duration translate into cross-country disparities in reported follow-up at 5 years of age.

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.

AIM: To assess the predictive validity of parent-reported gross motor impairment (GMI) at age 2 years to detect significant movement difficulties at age 5 years in children born extremely preterm. METHOD: Data were from 556 children (270 males, 286 females) born at less than 28 weeks' gestation in 2011 to 2012 in 10 European countries. Parent report of moderate/severe GMI was defined as walking unsteadily or unable to walk unassisted at 2 years corrected age. Examiners assessed significant movement difficulties (score ≤ 5th centile on the Movement Assessment Battery for Children, Second Edition) and diagnoses of cerebral palsy (CP) were collected by parent report at 5 years chronological age. RESULTS: At 2 years, 66 (11.9%) children had moderate/severe GMI. At 5 years, 212 (38.1%) had significant movement difficulties. Parent reports of GMI at age 2 years accurately classified CP at age 5 years in 91.0% to 93.2% of children. Classification of moderate/severe GMI at age 2 years had high specificity (96.2%; 95% confidence interval 93.6-98.0) and positive predictive value (80.3%; 68.7-89.1) for significant movement difficulties at age 5 years. However, 74.5% of children with significant movement difficulties at 5 years were not identified with moderate/severe GMI at age 2 years, resulting in low sensitivity (25.1%; 19.4-31.5). INTERPRETATION: This questionnaire may be used to identify children born extremely preterm who at age 2 years have a diagnosis of CP or movement difficulties that are likely to have a significant impact on their functional outcomes at age 5 years.

PURPOSE: This study aims to (1) describe the health-related quality of life (HRQoL) outcomes experienced by children born very preterm (28-31 weeks' gestation) and extremely preterm (< 28 weeks' gestation) at five years of age and (2) explore the mediation effects of bronchopulmonary dysplasia (BPD) and severe non-respiratory neonatal morbidity on those outcomes. METHODS: This investigation was based on data for 3687 children born at < 32 weeks' gestation that contributed to the EPICE and SHIPS studies conducted in 19 regions across 11 European countries. Descriptive statistics and multi-level ordinary linear squares (OLS) regression were used to explore the association between perinatal and sociodemographic characteristics and PedsQL™ GCS scores. A mediation analysis that applied generalised structural equation modelling explored the association between potential mediators and PedsQL™ GCS scores. RESULTS: The multi-level OLS regression (fully adjusted model) revealed that birth at < 26 weeks' gestation, BPD status and experience of severe non-respiratory morbidity were associated with mean decrements in the total PedsQL™ GCS score of 0.35, 3.71 and 5.87, respectively. The mediation analysis revealed that the indirect effects of BPD and severe non-respiratory morbidity on the total PedsQL™ GCS score translated into decrements of 1.73 and 17.56, respectively, at < 26 weeks' gestation; 0.99 and 10.95, respectively, at 26-27 weeks' gestation; and 0.34 and 4.80, respectively, at 28-29 weeks' gestation (referent: birth at 30-31 weeks' gestation). CONCLUSION: The findings suggest that HRQoL is particularly impaired by extremely preterm birth and the concomitant complications of preterm birth such as BPD and severe non-respiratory morbidity.

OBJECTIVES: To describe parent-reported healthcare service use at age 5 years in children born very preterm and investigate whether perinatal and social factors and the use of very preterm follow-up services are associated with high service use. STUDY DESIGN: We used data from an area-based cohort of births at <32 weeks of gestation from 11 European countries, collected from birth records and parental questionnaires at 5 years of age. Using the published literature, we defined high use of outpatient/inpatient care (≥4 sick visits to general practitioners, pediatricians, or nurses, ≥3 emergency room visits, or ≥1 overnight hospitalization) and specialist care (≥2 different specialists or ≥3 visits). We also categorized countries as having either a high or a low rate of children using very preterm follow-up services at age 5 years. RESULTS: Overall, 43% of children had high outpatient/inpatient care use and 48% had high specialist care use during the previous year. Perinatal factors were associated with high outpatient/inpatient and specialist care use, with a more significant association with specialist services. Associations with intermediate parental educational level and unemployment were stronger for outpatient/inpatient services. Living in a country with higher rates of very preterm follow-up service use was associated with lower use of outpatient/inpatient services. CONCLUSIONS: Children born very preterm had high healthcare service use at age 5 years, with different patterns for outpatient/inpatient and specialist care by perinatal and social factors. Longer follow-up of children born very preterm may improve care coordination and help avoid undesirable health service use.

BACKGROUND: This study aims to estimate the economic costs of care provided to children born very preterm and extremely preterm across 11 European countries, and to understand what perinatal and socioeconomic factors contribute to higher costs. METHODS: Generalised linear modelling was used to explore the association between perinatal and sociodemographic characteristics and total economic costs (, 2016 prices) during the fifth year of life. RESULTS: Lower gestational age was associated with increased mean societal costs of 2755 (p < 0.001), 752 (p < 0.01) and 657 (p < 0.01) for children born at < 26, 26-27 and 28-29 weeks, respectively, in comparison to the reference group born at 30-31 weeks. A sensitivity analyses that excluded variables (BPD, any neonatal morbidity and presence of congenital anomaly) plausibly lying on the causal pathway between gestational age at birth and economic outcomes elevated incremental societal costs by 1482, 763 and 144 at < 26, 26-27 and 28-29 weeks, respectively, in comparison to the baseline model. CONCLUSION: This study provides new evidence about the main cost drivers associated with preterm birth in European countries. Evidence identified by this study can act as inputs within cost-effectiveness models for preventive or treatment interventions for preterm birth. IMPACT: What is the key message of your article? This study provides new evidence about the magnitude and drivers of economic costs associated with preterm birth in European countries. What does it add to the existing literature? Lower gestational age is associated with increased mean societal costs during mid-childhood with indirect costs representing a key driver of increased costs. What is the impact? For policy makers, this study adds to sparse evidence about the main cost drivers associated with preterm birth in European countries beyond the first 2 years of life.

AIM: To (1) determine the proportion of 5-year-old children born extremely preterm (EPT) with movement difficulties including cerebral palsy (CP) and the proportion of these children receiving motor-related health care (MRHC), and (2) describe factors associated with receiving MRHC. METHOD: Children born before 28 weeks' gestation in 2011 to 2012 in 11 European countries were assessed with the Movement Assessment Battery for Children, Second Edition (MABC-2) at 5 years of age. Information on family characteristics, child health including CP diagnosis, and health care use were collected using parent-report questionnaires. MRHC was defined as visits in the previous year with health care providers (physical and occupational therapists) specialized in assessing/treating motor problems. We analysed receipt of MRHC and associated factors among children at risk of movement difficulties (MABC-2 score 6th-15th centiles), with significant movement difficulties (SMD; ≤5th centile) or with CP. RESULTS: Of 807 children assessed at 5 years 7 months (SD 4 months; 4 years 7 months-7 years 1 month), 412 were males (51.1%), 170 (21.1%) were at risk of movement difficulties, 201 (24.9%) had SMD, and 92 (11.4%) had CP. Those who received MRHC comprised 89.1% of children with CP, 42.8% with SMD, and 25.9% at risk of movement difficulties. MRHC for children with SMD varied from 23.3% to 66.7% between countries. Children were more likely to receive MRHC if they had other developmental problems or socioemotional, conduct, or attention difficulties. INTERPRETATION: Efforts are needed to increase MRHC for 5-year-old children born EPT with movement difficulties. WHAT THIS PAPER ADDS: Children born extremely preterm without cerebral palsy frequently experienced motor difficulties. Most of these children were not receiving motor-related health care (MRHC). Large geographical differences throughout Europe were observed in receipt of MRHC. Socioemotional problems were related to MRHC use.

BACKGROUND: Follow-up of very preterm infants is essential for reducing risks of health and developmental problems and relies on parental engagement. We investigated parents' perceptions of post-discharge healthcare for their children born very preterm in a European multi-country cohort study. METHODS: Data come from a 5-year follow-up of an area-based cohort of births <32 weeks' gestation in 19 regions from 11 European countries. Perinatal data were collected from medical records and 5-year data from parent-report questionnaires. Parents rated post-discharge care related to their children's preterm birth (poor/fair/good/excellent) and provided free-text suggestions for improvements. We analyzed sociodemographic and medical factors associated with poor/fair ratings, using inverse probability weights to adjust for attrition bias, and assessed free-text responses using thematic analysis. RESULTS: Questionnaires were returned for 3635 children (53.8% response rate). Care was rated as poor/fair for 14.2% [from 6.1% (France) to 31.6% (Denmark)]; rates were higher when children had health or developmental problems (e.g. cerebral palsy (34.4%) or epilepsy (36.9%)). From 971 responses, 4 themes and 25 subthemes concerning care improvement were identified. CONCLUSIONS: Parents' experiences provide guidance for improving very preterm children's post-discharge care; this is a priority for children with health and developmental problems as parental dissatisfaction was high. IMPACT: In a European population-based very preterm birth cohort, parents rated post-discharge healthcare as poor or fair for 14.2% of children, with a wide variation (6.1-31.6%) between countries. Dissatisfaction was reported in over one-third of cases when children had health or developmental difficulties, such as epilepsy or cerebral palsy. Parents' free-text suggestions for improving preterm-related post-discharge healthcare were similar across countries; these focused primarily on better communication with parents and better coordination of care. Parents' lived experiences are a valuable resource for understanding where care improvements are needed and should be included in future research.

AIM: Children born very preterm require additional specialist care because of the health and developmental risks associated with preterm birth, but information on their health service use is sparse. We sought to describe the use of specialist services by children born very preterm in Europe. METHOD: We analysed data from the multi-regional, population-based Effective Perinatal Intensive Care in Europe (EPICE) cohort of births before 32 weeks' gestation in 11 European countries. Perinatal data were abstracted from medical records and parents completed a questionnaire at 2 years corrected age (4322 children; 2026 females, 2296 males; median gestational age 29wks, interquartile range [IQR] 27-31wks; median birthweight 1230g, IQR 970-1511g). We compared parent-reported use of specialist services by country, perinatal risk (based on gestational age, small for gestational age, and neonatal morbidities), maternal education, and birthplace. RESULTS: Seventy-six per cent of the children had consulted at least one specialist, ranging across countries from 53.7% to 100%. Ophthalmologists (53.4%) and physiotherapists (48.0%) were most frequently consulted, but individual specialists varied greatly by country. Perinatal risk was associated with specialist use, but the gradient differed across countries. Children with more educated mothers had higher proportions of specialist use in three countries. INTERPRETATION: Large variations in the use of specialist services across Europe were not explained by perinatal risk and raise questions about the strengths and limits of existing models of care. WHAT THIS PAPER ADDS: Use of specialist services by children born very preterm varied across Europe. This variation was observed for types and number of specialists consulted. Perinatal risk was associated with specialist care, but did not explain country-level differences. In some countries, mothers' educational level affected use of specialist services.
UTILIZACIÓN DE SERVICIOS DE SALUD ESPECIALIZADOS EN UN ESTUDIO DE COHORTE EUROPEO DE NIÑOS NACIDOS MUY PREMATUROS: OBJETIVO: Niños nacidos muy prematuramente requieren cuidados especializados adicionales debido a su salud y a los riesgos asociados con la prematuros, sin embargo la información sobre el uso de servicios de salud es escasa. Buscamos describir la utilización de servicios especializados por niños nacidos muy prematuramente, en Europa. MÉTODO: Analizamos datos de una cohorte de nacimientos ocurridos antes de las 32 semanas de gestación tomados del Effective Perinatal Intensive Care in Europe (EPICE), basado en la población y multirregional, en 11 países europeos. Los datos perinatales fueron extraídos de las historias clínicas y los padres completaron un cuestionario a los 2 años de edad corregida (4.322 niños; 2026 sexo femenino, 2.296 masculino; edad gestacional mediana 29 semanas, rango intercuartílico (IQR) 27-31 semanas; mediana de peso de nacimiento 1.230 gr, IQR 970-1.511 gr). Comparamos el uso de servicios especializados (según informe de los padres) por país, riesgo perinatal (basado en edad gestacional, bajo peso para edad gestacional y morbilidades neonatales), educación materna y lugar de nacimiento. RESULTADOS: En total 65% de los niños habían consultado por lo menos a un especialista, con un rango entre países de 53,7% a 100%. Los especialistas más frecuentemente consultados fueron Oftalmólogos (53,4%) y Fisioterapeutas (48%) pero los especialistas consultados por cada individuo variaron mucho según el país. El riesgo perinatal se asoció al uso de especialista, pero el gradiente varió entre los países. Niños de madres con mayor nivel educativo tuvieron mayor proporción de uso de especialistas en tres países. INTERPRETACIÓN: Las grandes variaciones en el uso de servicios especializados en Europa no fueron explicadas por el riesgo perinatal y arrojan cuestionamientos sobre las fortalezas y limitaciones de los modelos de cuidados existentes.

Procuramos descrever o uso de serviços especializados por crianças nascidas muito prematuras na Europa. MÉTODO: Analisamos dados de uma coorte populacional multi-regional, do Cuidado Intensivo Neonatal Efetivo na Europa (EPICE), com lactentes nascidos antes de 32 semanas de gestação em 11 países europeus. Dados perinatais foram extraídos dos registros médicos, e os pais completaram um questionário com 2 anos de idade corrigida (4.322 crianças; 2.026 do sexo feminino, 2.296 do sexo masculino; idade gestacional mediana 29semanas, intervalo interquartile [IIQ] 27-31sem; peso ao nascimento mediano 1,230g, IIQ 970-1511g). Comparamos o uso de serviços especializados reportados pelos pais por país, risco perinatal (com base na idade gestacional, pequeno para a idade gestacional e morbidades neonatais), educação materna e local de nascimento. RESULTADOS: Setenta e seis por cento das crianças consultou pelo menos um especialista, variando entre países de 53,7 a 100%. Oftalmologistas (53,4%) e fisioterapeutas (48,0%) foram os mais frequentemente consultados, mas os especialistas individuais variaram bastante por país. O risco perinatal se associou com uso de serviços especializados, mas o gradient diferiu entre países. Crianças com mães mais educadas tinham maior proporção de uso de especialistas em três países. INTERPRETAÇÃO: Grandes variações no uso de serviços especializados na Europa não foram explicadas pelo risco perinatal, e levantam questões sobre as forças e limitações dos modelos de cuidado existentes.

Climate change is one of the largest threats to population health and has already affected the ecosystem, food production, and health and wellbeing of populations all over the world. The healthcare sector is responsible for around 5 % of greenhouse gas emissions worldwide and can play a key role in reducing global warming. This narrative review summarized the information on the role of healthcare systems in addressing climate change and strategies for reducing its negative impact to illustrate different types of actions that can support the ecological transformation of healthcare systems to help reaching sustainable development goals. A wide range of green interventions are shown to be effective to reduce the carbon footprint of healthcare and can have a meaningful impact if implemented systematically. However, these would not suffice unless accompanied by systemic mitigation strategies altering how healthcare is provided and consumed. Sustainable healthcare strategies such as reducing waste and low-value care will have direct benefits for the environment while improving economic and health outcomes. The healthcare sector has a unique opportunity to leverage its position and resources to provide a comprehensive strategy for fighting climate change and improving population health and the environment on which it depends.

The excess cancer mortality in persons with severe mental illness (SMI) has been well documented, and research suggests that it may be influenced by care-related factors. Our objective was to assess breast cancer care pathways in women with SMI in France, using an exhaustive population-based data-linkage study with a matched case-control design. The cases were 1346 women with incident breast cancer in 2013/2014 and preexisting SMI who were matched with three controls without SMI presenting similar demographics, initial breast cancer type, and year of incidence. We compared cancer care pathways and their quality for cases and controls, using a consensual set of indicators covering diagnosis, treatment, follow-up, and mortality (until 2017). After adjusting for covariates, cases had lower odds to undergo the main diagnostic tests, lumpectomy, adjuvant chemotherapy, and radiotherapy, as well as hormone therapy, but higher odds for mastectomy. Suboptimal quality in cancer pathways was observed for both groups, but to a higher extent for cases, especially for not receiving timely care after diagnosis and post-treatment follow-up. Breast cancer mortality, considering competing risks of deaths, was significantly elevated in women with SMI. These findings highlight disparities in cancer care pathways for individuals with SMI, as well as specific aspects of the care continuum which could benefit from targeted actions to reach equity of outcomes.
RESUMO
This review of the French health system analyses recent developments in health organisation and governance, financing, healthcare provision, recent reforms and health system performance. Overall health status continues to improve in France, although geographic and socioeconomic inequalities in life expectancy persist. The health system combines a social health insurance (SHI) model with an important role for tax-based revenues to finance healthcare. The health system provides universal coverage, with a broad benefits basket, but cost-sharing is required for all essential services. Private complementary insurance to cover these costs results in very low average out-of-pocket (OOP) payments, although there are concerns regarding solidarity, financial redistribution and efficiency in the health system. The macroeconomic context in the last couple of years in the country has been affected by the Covid-19 pandemic, which resulted in subsequent increases of total health expenditure in France in 2020 (3.7%) and 2021 (9.8%). Healthcare provision continues to be highly fragmented in France, with a segmented approach to care organization and funding across primary, secondary and long-term care. Recent reforms aim to strengthen primary care by encouraging multidisciplinary group practices, while public health efforts over the last decade have focused on boosting prevention strategies and tackling lifestyle risk factors, such as smoking and obesity with limited success. Continued challenges include ensuring the sustainability of the health workforce, particularly to secure adequate numbers of health professionals in medically underserved areas, such as rural and less affluent communities, and improving working conditions, remuneration and career prospects, especially for nurses, to support retention. The Covid-19 pandemic has brought to light some structural weaknesses within the French health system, but it has also provided opportunities for improving its sustainability. There has been a notable shift in the will to give more room to decision-making at the local level, involving healthcare professionals, and to find new ways of funding healthcare providers to encourage care coordination and integration.

Background: As childbearing is postponed in developed countries, maternal age (MA) has increased over decades with an increasing number of pregnancies between age 35-39 and beyond. The aim of the study was to determine the influence of advanced (AMA) and very advanced maternal age (vAMA) on morbidity and mortality of very preterm (VPT) infants. Methods: This was a population-based cohort study including infants from the "Effective Perinatal Intensive Care in Europe" (EPICE) cohort. The EPICE database contains data of 10329 VPT infants of 8,928 mothers, including stillbirths and terminations of pregnancy. Births occurred in 19 regions in 11 European countries. The study included 7,607 live born infants without severe congenital anomalies. The principal exposure variable was MA at delivery. Infants were divided into three groups [reference 18-34 years, AMA 35-39 years and very(v) AMA ≥40 years]. Infant mortality was defined as in-hospital death before discharge home or into long-term pediatric care. The secondary outcome included a composite of mortality and/or any one of the following major neonatal morbidities: (1) moderate-to-severe bronchopulmonary dysplasia; (2) severe brain injury defined as intraventricular hemorrhage and/or cystic periventricular leukomalacia; (3) severe retinopathy of prematurity; and (4) severe necrotizing enterocolitis. Results: There was no significant difference between MA groups regarding the use of surfactant therapy, postnatal corticosteroids, rate of neonatal sepsis or PDA that needed pharmacological or surgical intervention. Infants of AMA/vAMA mothers required significantly less mechanical ventilation during NICU stay than infants born to non-AMA mothers, but there was no significant difference in length of mechanical ventilation and after stratification by gestational age group. Adverse neonatal outcomes in VPT infants born to AMA/vAMA mothers did not differ from infants born to mothers below the age of 35. Maternal age showed no influence on mortality in live-born VPT infants. Conclusion: Although AMA/vAMA mothers encountered greater pregnancy risk, the mortality and morbidity of VPT infants was independent of maternal age.
RESUMO
BACKGROUND: Socioeconomic factors influence language development in the general population, but the association remains poorly documented in children born very preterm (VPT). We assessed the impact of maternal education on language development in children born VPT and effect modification by perinatal risk. METHODS: Data were from the Effective Perinatal Intensive Care in Europe (EPICE) population-based cohort of children born <32 weeks' gestational age (GA) in 2011/2012. Regions from six countries (Estonia, France, Germany, Italy, Sweden and UK) used a validated short form MacArthur Developmental Communicative Inventories Checklist to assess language at 2 years corrected age. Perinatal variables were collected from clinical records. We assessed expressive language delay (ELD), defined as (a) not combining words; and (b) expressive vocabulary <10th percentile of norms for age and sex. Perinatal risk (low, moderate and high) was determined using GA, small for GA and neonatal morbidities. We estimated adjusted risk ratios (aRR) of ELD by maternal education with inverse weighting to account for non-response bias. RESULTS: Of 2741 children, 24.6% were not combining words and 39.7% had a low expressive vocabulary. Low maternal education (lower secondary or less compared with a bachelor's degree or more) increased risks of ELD: not combining words: aRR=1.52 (95% CI 1.36 to 1.69); low expressive vocabulary: aRR=1.25 (1.04 to 1.51). For children with low perinatal risk, the aRR were 1.88 (1.26 to 2.80) and 1.44 (1.06 to 1.95), respectively, compared with those with high perinatal risks: 1.36 (1.10 to 1.67) and 1.11 (0.97 to 1.27), respectively. CONCLUSION: Low maternal education affects ELD for children born VPT, although the association appears attenuated among those with highest perinatal risk.
