Trends in hospital admissions during transition from paediatric to adult services for young people with learning disabilities or autism: Population-based cohort study. Lancet Reg Health Eur 2023; 24:100531. [PMID: 36394000 PMCID: PMC9649375 DOI: 10.1016/j.lanepe.2022.100531] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/21/2022] [Revised: 09/22/2022] [Accepted: 10/03/2022] [Indexed: 11/11/2022] Open
Abstract
Background Transition from paediatric to adult health care may disrupt continuity of care, and result in unmet health needs. We describe changes in planned and unplanned hospital admission rates before, during and after transition for young people with learning disability (LD), or autism spectrum disorders (ASD) indicated in hospital records, who are likely to have more complex health needs. Methods We developed two mutually exclusive cohorts of young people with LD, and with ASD without LD, born between 1990 and 2001 in England using national hospital admission data. We determined the annual rate of change in planned and unplanned hospital admission rates before (age 10–15 years), during (16–18 years) and after (19–24 years) transition to adult care using multilevel negative binomial regression models, accounting for area-level deprivation, sex, birth year and presence of comorbidities. Findings The cohorts included 51,291 young people with LD, and 46,270 autistic young people. Admission rates at ages 10–24 years old were higher for young people with LD (54 planned and 25 unplanned admissions per 100 person-years) than for autistic young people (17/100 and 16/100, respectively). For young people with LD, planned admission rates were highest and constant before transition (rate ratio [RR]: 0.99, 95% confidence interval [CI] 0.98–0.99), declined by 14% per year of age during (RR: 0.86, 95% CI: 0.85–0.88), and remained constant after transition (RR: 0.99, 95% CI: 0.99–1.00), mainly due to fewer admissions for non-surgical care, including respite care. Unplanned admission rates increased by 3% per year of age before (RR: 1.03, 95% CI: 1.02–1.03), remained constant during (RR: 1.01, 95% CI: 1.00–1.03) and increased by 3% per year after transition (RR: 1.03, 95% CI: 1.02–1.04). For autistic young people, planned admission rates increased before (RR: 1.06, 95% CI: 1.05–1.06), decreased during (RR: 0.95, 95% CI: 0.93–0.97), and increased after transition (RR: 1.05, 95%: 1.04–1.07). Unplanned admission rates increased most rapidly before (RR: 1.16, 95% CI: 1.15–1.17), remained constant during (RR: 1.01, 95% CI: 0.99–1.03), and increased moderately after transition (RR: 1.03, 95% CI: 1.02–1.04). Interpretation Decreases in planned admission rates during transition were paralleled by small but consistent increases in unplanned admission rates with age for young people with LD and autistic young people. Decreases in non-surgical planned care during transition could reflect disruptions to continuity of planned/respite care or a shift towards provision of healthcare in primary care and community settings and non-hospital arrangements for respite care.

Mental health service use among mothers involved in public family law proceedings: linked data cohort study in South London 2007-2019. Soc Psychiatry Psychiatr Epidemiol 2022; 57:2097-2108. [PMID: 35294976 PMCID: PMC9477900 DOI: 10.1007/s00127-022-02221-1] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/23/2021] [Accepted: 01/06/2022] [Indexed: 11/29/2022]
Abstract
PURPOSE Mental health problems and substance misuse are common among the mothers of children who experience court-mandated placement into care in England, yet there is limited research characterising these health needs to inform evidence-based policy. In this descriptive study, we aimed to generate evidence about the type, severity, and timing of mental health and substance misuse needs among women involved in public family law proceedings concerning child placement into care ('care proceedings'). METHODS This is a retrospective, matched cohort study using linked family court and mental health service records for 2137 (66%) of the 3226 women involved in care proceedings between 2007 and 2019 in the South London and Maudsley NHS Mental Health Trust (SLaM) catchment area. We compared mental health service use and risk of dying with 17,096 female-matched controls who accessed SLaM between 2007 and 2019, aged 16-55 years, and were not involved in care proceedings. RESULTS Most women (79%) were known to SLaM before care proceedings began. Women had higher rates of schizophrenia spectrum disorders (19% vs 11% matched controls), personality disorders (21% vs 11%), and substance misuse (33% vs 12%). They were more likely to have a SLaM inpatient admission (27% vs 14%) or to be sectioned (19% vs 8%). Women had a 2.15 (95% CI 1.68-2.74) times greater hazard of dying, compared to matched controls, adjusted for age. CONCLUSION Women involved in care proceedings experience a particularly high burden of severe and complex mental health and substance misuse need. Women's increased risk of mortality following proceedings highlights that interventions responding to maternal mental health and substance misuse within family courts should offer continued, long-term support.

SARS-CoV-2 tests, confirmed infections and COVID-19-related hospital admissions in children and young people: birth cohort study. BMJ Paediatr Open 2022; 6:10.1136/bmjpo-2022-001545. [PMID: 36053647 PMCID: PMC9437731 DOI: 10.1136/bmjpo-2022-001545] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/13/2022] [Accepted: 08/05/2022] [Indexed: 11/05/2022] Open
Abstract
BACKGROUND There have been no population-based studies of SARS-CoV-2 testing, PCR-confirmed infections and COVID-19-related hospital admissions across the full paediatric age range. We examine the epidemiology of SARS-CoV-2 in children and young people (CYP) aged <23 years. METHODS We used a birth cohort of all children born in Scotland since 1997, constructed via linkage between vital statistics, hospital records and SARS-CoV-2 surveillance data. We calculated risks of tests and PCR-confirmed infections per 1000 CYP-years between August and December 2020, and COVID-19-related hospital admissions per 100 000 CYP-years between February and December 2020. We used Poisson and Cox proportional hazards regression models to determine risk factors. RESULTS Among the 1 226 855 CYP in the cohort, there were 378 402 tests (a rate of 770.8/1000 CYP-years (95% CI 768.4 to 773.3)), 19 005 PCR-confirmed infections (179.4/1000 CYP-years (176.9 to 182.0)) and 346 admissions (29.4/100 000 CYP-years (26.3 to 32.8)). Infants had the highest COVID-19-related admission rates. The presence of chronic conditions, particularly multiple types of conditions, was strongly associated with COVID-19-related admissions across all ages. Overall, 49% of admitted CYP had at least one chronic condition recorded. CONCLUSIONS Infants and CYP with chronic conditions are at highest risk of admission with COVID-19. Half of admitted CYP had chronic conditions. Studies examining COVID-19 vaccine effectiveness among children with chronic conditions and whether maternal vaccine during pregnancy prevents COVID-19 admissions in infants are urgently needed.

What makes administrative data "research-ready"? A systematic review and thematic analysis of published literature. Int J Popul Data Sci 2022; 7:1718.

Abstract
Introduction Administrative data are a valuable research resource, but are under-utilised in the UK due to governance, technical and other barriers (e.g., the time and effort taken to gain secure data access). In recent years, there has been considerable government investment in making administrative data "research-ready", but there is no definition of what this term means. A common understanding of what constitutes research-ready administrative data is needed to establish clear principles and frameworks for their development and the realisation of their full research potential. Objective To define the characteristics of research-ready administrative data based on a systematic review and synthesis of existing literature. Methods On 29th June 2021, we systematically searched seven electronic databases for (1) peer-reviewed literature (2) related to research-ready administrative data (3) written in the English language. Following supplementary searches and snowball screening, we conducted a thematic analysis of the identified relevant literature. Results Overall, we screened 2,375 records and identified 38 relevant studies published between 2012 and 2021. Most related to administrative data from the UK and US and particularly to health data. The term research-ready was used inconsistently in the literature and there was some conflation with the concept of data being ready for statistical analysis. From the thematic analysis, we identified five defining characteristics of research-ready administrative data: (a) accessible, (b) broad, (c) curated, (d) documented and (e) enhanced for research purposes. Conclusions Our proposed characteristics of research-ready administrative data could act as a starting point to help data owners and researchers develop common principles and standards. In the more immediate term, the proposed characteristics are a useful framework for cataloguing existing research-ready administrative databases and relevant resources that can support their development.

Hospital admissions for stress-related presentations among school-aged adolescents during term time versus holidays in England: weekly time series and retrospective cross-sectional analysis. BJPsych Open 2021; 7:e215.

Abstract
BACKGROUND Schools are a potential stressor for adolescents and may contribute to emergency hospital admissions. AIMS We describe rates of stress-related presentations (SRPs) among school-aged adolescents (11-17 years) during school terms and holidays, and explore differences by age and gender. METHOD Using national administrative hospital data, we defined an SRP as an emergency hospital admission with a primary diagnosis related to pain, psychosomatic symptoms (e.g. fatigue) or mental health problems, or with self-harm indicated in any diagnostic position. We estimated incidence rate ratios for weekly SRPs in term time versus holidays from 2014-2015 to 2017-2018, using negative binomial regression models, stratified by age and gender. We estimated the cumulative incidence of any SRP between 11 and 17 years by analysing prior hospital admission histories of adolescents with an SRP in 2017-2018. RESULTS Over the 4-year study period, 305 491 SRPs in 171 013 school-aged adolescents accounted for 31% of emergency admissions for this group. SRPs were predominantly for mental health problems or self-harm (38%), or pain (35%). Weekly admission rates for SRPs were higher in term time than holidays for all ages (age-specific incidence rate ratios were 1.15-1.49 for girls and 1.08-1.60 for boys). Rates were highest for girls aged 14 and 15 years. The estimated cumulative incidence of any SRP between 11 and 17 years was 7.9% for girls and 4.1% for boys. CONCLUSIONS Hospital admissions for SRPs are common among adolescents, affecting around two girls and one boy in every classroom. Higher rates in term time than holidays suggest that school factors may contribute.

Abstract
Objectives To demonstrate the challenges of interpreting cross-country comparisons of
paediatric asthma hospital admission rates as an indicator of primary care
quality. Methods We used hospital administrative data from >10 million children aged 6–15
years, resident in Austria, England, Finland, Iceland, Ontario (Canada),
Sweden or Victoria (Australia) between 2008 and 2015. Asthma hospital
admission and emergency department (ED) attendance rates were compared
between countries using Poisson regression models, adjusted for age and
sex. Results Hospital admission rates for asthma per 1000 child-years varied eight-fold
across jurisdictions. Admission rates were 3.5 times higher when admissions
with asthma recorded as any diagnosis were considered, compared with
admissions with asthma as the primary diagnosis. Iceland had the lowest
asthma admission rates; however, when ED attendance rates were considered,
Sweden had the lowest rate of asthma hospital contacts. Conclusions The large variations in childhood hospital admission rates for asthma based
on the whole child population reflect differing definitions, admission
thresholds and underlying disease prevalence rather than primary care
quality. Asthma hospital admissions among children diagnosed with asthma is
a more meaningful indicator for inter-country comparisons of primary care
quality.

Abstract
INTRODUCTION The coronavirus (COVID-19) pandemic has caused significant global mortality and impacted lives around the world. Virus Watch aims to provide evidence on which public health approaches are most likely to be effective in reducing transmission and impact of the virus, and will investigate community incidence, symptom profiles and transmission of COVID-19 in relation to population movement and behaviours. METHODS AND ANALYSIS Virus Watch is a household community cohort study of acute respiratory infections in England and Wales and will run from June 2020 to August 2021. The study aims to recruit 50 000 people, including 12 500 from minority ethnic backgrounds, for an online survey cohort and monthly antibody testing using home fingerprick test kits. Nested within this larger study will be a subcohort of 10 000 individuals, including 3000 people from minority ethnic backgrounds. This cohort of 10 000 people will have full blood serology taken between October 2020 and January 2021 and repeat serology between May 2021 and August 2021. Participants will also post self-administered nasal swabs for PCR assays of SARS-CoV-2 and will follow one of three different PCR testing schedules based on symptoms. ETHICS AND DISSEMINATION This study has been approved by the Hampstead National Health Service (NHS) Health Research Authority Ethics Committee (ethics approval number 20/HRA/2320). We are monitoring participant queries and using these to refine methodology where necessary, and are providing summaries and policy briefings of our preliminary findings to inform public health action by working through our partnerships with our study advisory group, Public Health England, NHS and government scientific advisory panels.

Abstract
INTRODUCTION Maternal mental health problems and substance misuse are key risk factors for child neglect or abuse and court-mandated placement into care. Linkage between mental health records and family court data could raise awareness about parent mental health needs and inform approaches to address them. OBJECTIVES To evaluate data linkage between administrative family court data and electronic mental health records for a population-based mental health service for 1.3 million people in South London. METHODS We deterministically linked administrative family court data for women (n=5463) involved in care proceedings in South London with service user records from the South London and Maudsley NHS Mental Health Trust (SLaM). We restricted the cohort to women involved in proceedings between 2007 and 2019, in local authorities where SLaM solely provides secondary/tertiary mental health services and the Improving Access to Psychological Therapies (IAPT) (n=3226). We analysed the associations between match status and sociodemographic/case characteristics using multivariable logistic regression. RESULTS Two-thirds (2317/3226; 66%) of women linked to a SLaM service user record at some point; most (91%) who linked accessed secondary/tertiary mental health services, indicating serious mental illness. Accounting for possible missed matches, we estimated that 70-83% of women accessed SLaM services at some point. Older women at index proceedings (>35yrs OR: 0.69, 95%CI: 0.54-0.88vs <25yrs) and Black women or women from other ethnic groups (Black ethnic groups 0.65, 0.50-0.83; other ethnicity 0.59, 0.43-0.81 vs White ethnic groups) had lower odds of linking. Odds of linking were higher for women with an infant in proceedings (1.42, 1.18-1.71), or with curtailed/terminated parental responsibility (1.44, 1.20-1.73). CONCLUSION Our linkage supports growing evidence of a high burden of mental health problems and substance misuse among women whose children enter care in England, compared to the general population. Research using this linkage should inform strategies to address the considerable mental health needs of vulnerable women and their children.

Abstract
IntroductionEvidence suggests that many women whose children enter care via family court proceedings (care proceedings) in England experience mental health and substance misuse problems. Further, an estimated 22% of women will return to court within 5 years for subsequent proceedings, often returning quickly with a new infant and with little time to address underlying health-related problems. With growing pressures on England’s family justice system and the wider children’s social care sector, there is a need to identify opportunities to engage with women in a healthcare setting to reduce the likelihood of (recurrent) care proceedings.
Objectives and ApproachWe used linked family court and mental health service data (n = 2843) for mothers who were referred to mental health services and were involved in care proceedings in South London between 2007 and 2019. We (1) describe differences in the frequency, type and timing of mental health and addictions service use between mothers who return to court and those who do not and (2) evaluate risk/protective factors for returning to court.
ResultsAfter resolving duplicate matches (n = 2808), 1028 women (36.6%) referred to mental health services over the study period subsequently returned to court. We will describe differences in characteristics of service use and care proceedings between women who return to court and those that do not. We will also explore a range of potential risk/protective factors for returning to court, including maternal age at first child, indicators for failure to engage with services, mental disorder type, substance misuse, and maternal neighbourhood deprivation status.
Conclusion / ImplicationsBetter understanding of how women use mental health and addictions services before, during and after proceedings, and identification of key risk/protective factors for returning to court, would inform strategies to reduce recurrent involvement in care proceedings among this population group.

Abstract
IntroductionAn estimated 23% of children in England are exposed to maternal mental health problems, with growing concern around how maternal mental health affects parenting capacity and entries into public care for their children. There is limited evidence on the prevalence of mental health service need among women whose children enter care and on whether these needs are sufficiently met. With England’s family justice system and children’s social care sector increasingly overstretched, there is a need to identify opportunities for an improved response to maternal mental health.
Objectives and ApproachWe linked administrative family court data for women (n = 5463) involved in public family court proceedings (care proceedings) across eight London boroughs between 2007 and 2019, with patient records from South London and Maudsley NHS mental health trust (SLaM). Work is ongoing to (1) describe the frequency, type and timing of mental health service use among women who link and (2) compare these findings to general population trends.
Results2843 (52%) women linked to a SLaM patient record via deterministic linkage. Matches had better recording of identifiers and were more likely to have returned to court than non-matches (36% vs 26%). The majority of women (75.0%) were referred for treatment before the start of their (first) care proceeding, while 34.8% had a diagnosis recorded in a structured field. To appraise linkage quality, we manually reviewed de-identified clinician notes for 100 randomly selected women who linked; we confirmed ‘true’ match status for 95 women and found no evidence contradicting match status for the remainder.
Conclusion / ImplicationsThis novel linkage between mental health and family court data supports growing evidence that women whose children enter care in England have high prevalence of mental health problems. Research using this linkage will help to inform strategies to improve maternal mental health and outcomes for vulnerable women and their children.

Characterizing newborn and older infant entries into care in England between 2006 and 2014. CHILD ABUSE & NEGLECT 2020; 109:104760. [PMID: 33053479 PMCID: PMC7718112 DOI: 10.1016/j.chiabu.2020.104760] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 07/24/2020] [Revised: 09/18/2020] [Accepted: 09/22/2020] [Indexed: 06/11/2023]
Abstract
BACKGROUND The risk of entry to state care during infancy is increasing, both here in England and abroad, with most entering within a week of birth ('newborns'). However, little is known about these infants or of their pathways through care over early childhood. OBJECTIVE To characterize infant entries to care in England. PARTICIPANTS AND SETTING All children in England who first entered care during infancy, between April 2006 and March 2014 (n = 42,000). METHODS We compared sociodemographic and care characteristics for infants entering care over the study period by age at first entry (newborn: <1wks, older infant 1-51wks). Among those who entered before April 2010, we further characterized care over follow-up (i.e. 4 years from first entry) and employed latent class analysis to uncover any common pathways through care. RESULTS Almost 40 % of infants first entered care as a newborn. Most infants first entered care under s 20 arrangements (i.e. out-of-court, 60 % of newborns vs 47 % of older infants). Among infants entering before April 2010, most were adopted over follow-up (60 % vs 37 %), though many were restored to parental care (20 % vs 32 %) or exited care to live with extended family (13 % vs 19 %). One in six infants (17.7 %) had particularly unstable care trajectories over early childhood, typified by three or more placements or failed reunification. CONCLUSIONS Evidence-based strengthening of pre-birth social work support is needed to improve preventive interventions before birth, to more effectively target infant placement into care. Linkages between child protection records and information on parents are needed to inform preventive strategies.

[PMID: 32444447 PMCID: PMC7588403 DOI: 10.1136/archdischild-2019-317902] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/11/2019] [Revised: 03/10/2020] [Accepted: 04/10/2020] [Indexed: 12/02/2022]
Abstract
OBJECTIVE To determine trends in emergency admission rates requiring different levels of critical care in hospitals with and without a paediatric intensive care unit (PICU). DESIGN Birth cohort study created from Hospital Episode Statistics. SETTING National Health Service funded hospitals in England. PATIENTS 8 577 680 singleton children born between 1 May 2003 and 31 April 2017. OUTCOME MEASURES Using procedure and diagnostic codes, we assigned indicators of high dependency care (eg, non-invasive ventilation) or intensive care (eg, invasive ventilation) to emergency admissions. INTERVENTIONS Children were followed up until their fifth birthday to estimate high dependency and intensive care admission rates in hospitals with and without a PICU. We tested the yearly trend of high dependency and intensive care admissions to hospitals without a PICU using logistic regression models. RESULTS Emergency admissions requiring high dependency care in hospitals without a PICU increased from 3.30 (95% CI 3.09 to 3.51) per 10 000 child-years in 2008/2009 to 7.58 (95% CI 7.28 to 7.89) in 2016/2017 and overtook hospitals with a PICU in 2015/2016. The odds of an admission requiring high dependency care to a hospital without a PICU compared with a hospital with a PICU increased by 9% per study year (OR 1.09, 95% CI 1.08 to 1.10). The same trend was not present for admissions requiring intensive care (OR 1.01, 95% CI 0.99 to 1.03). CONCLUSIONS Between 2008/2009 and 2016/2017, an increasing proportion of admissions with indicators of high dependency care took place in hospitals without a PICU.

Timing of paediatric orchidopexy in universal healthcare systems: international administrative data cohort study. BJS Open 2020; 4:1117-1124. [PMID: 32706149 PMCID: PMC7709362 DOI: 10.1002/bjs5.50329] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/11/2020] [Accepted: 06/24/2020] [Indexed: 01/23/2023] Open
Abstract
BACKGROUND International guidelines in 2008 recommended orchidopexy for undescended testis at 6-12 months of age to reduce the risk of testicular cancer and infertility. Using administrative data from England, Finland, Ontario (Canada), Scotland and Sweden (with data from Victoria (Australia) and Iceland in supplementary analyses), the aim of this study was to investigate compliance with these guidelines and identify potential socioeconomic inequities in the timing of surgery before 1 and 3 years. METHODS All boys born in 2003-2011 with a diagnosis code of undescended testis and procedure codes indicating orchidopexy before their fifth birthday were identified from administrative health records. Trends in the proportion of orchidopexies performed before 1 and 3 years of age were investigated, as were socioeconomic inequities in adherence to the guidelines. RESULTS Across all jurisdictions, the proportion of orchidopexies occurring before the first birthday increased over the study period. By 2011, from 7·6 per cent (Sweden) to 27·9 per cent (Scotland) of boys had undergone orchidopexy by their first birthday and 71·5 per cent (Sweden) to 90·4 per cent (Scotland) by 3 years of age. There was limited evidence of socioeconomic inequities for orchidopexy before the introduction of guidelines (2008). Across all jurisdictions for boys born after 2008, there was consistent evidence of inequities in orchidopexy by the first birthday, favouring higher socioeconomic position. Absolute differences in these proportions between the highest and lowest socioeconomic groups ranged from 2·5 to 5·9 per cent across jurisdictions. CONCLUSION Consistent lack of adherence to the guidelines across jurisdictions questions whether the guidelines are appropriate.

Evaluating the real-world implementation of the Family Nurse Partnership in England: protocol for a data linkage study. BMJ Open 2020; 10:e038530. [PMID: 32430455 PMCID: PMC7239518 DOI: 10.1136/bmjopen-2020-038530] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/13/2020] [Revised: 04/01/2020] [Accepted: 04/02/2020] [Indexed: 02/01/2023] Open
Abstract
INTRODUCTION Almost 20 000 babies are born to teenage mothers each year in England, with poorer outcomes for mothers and babies than among older mothers. A nurse home visitation programme in the USA was found to improve a wide range of outcomes for young mothers and their children. However, a randomised controlled trial in England found no effect on short-term primary outcomes, although cognitive development up to age 2 showed improvement. Our study will use linked routinely collected health, education and social care data to evaluate the real-world effects of the Family Nurse Partnership (FNP) on child outcomes up to age 7, with a focus on identifying whether the FNP works better for particular groups of families, thereby informing programme targeting and resource allocation. METHODS AND ANALYSIS We will construct a retrospective cohort of all women aged 13-24 years giving birth in English NHS hospitals between 2010 and 2017, linking information on mothers and children from FNP programme data, Hospital Episodes Statistics and the National Pupil Database. To assess the effectiveness of FNP, we will compare outcomes for eligible mothers ever and never enrolled in FNP, and their children, using two analysis strategies to adjust for measured confounding: propensity score matching and analyses adjusting for maternal characteristics up to enrolment/28 weeks gestation. Outcomes of interest include early childhood development, childhood unplanned hospital admissions for injury or maltreatment-related diagnoses and children in care. Subgroup analyses will determine whether the effect of FNP varied according to maternal characteristics (eg, age and education). ETHICS AND DISSEMINATION The Nottingham Research Ethics Committee approved this study. Mothers participating in FNP were supportive of our planned research. Results will inform policy-makers for targeting home visiting programmes. Methodological findings on the accuracy and reliability of cross-sectoral data linkage will be of interest to researchers.

Abstract
Introduction In England, in cases of child maltreatment or neglect, the state can intervene through the family court to remove children from their family home and place them in out-of-home care. The Children and Family Court Advisory and Support Service (Cafcass) collects and maintains administrative records of all public family law cases in England. While these national records are primarily used to monitor and manage the workflow of Cafcass teams across England, researchers have re-purposed this data for analysis to understand the drivers and outcomes of public family law intervention. Data contents The administrative dataset is a reflection of the cases Cafcass is involved with and the extent of that involvement. The dataset contains information about the local authority that makes an application to initiate public family law proceedings, the children and families involved, and the duration and details of the case. Between 1 April 2007 and 31 March 2019, Cafcass captured information on approximately 172,100 public family law cases, involving 282,300 children, and 349,600 adults (of which 289,300 are recorded as biological parents). Amongst the information recorded are the relations between adults and children, making it possible for researchers to identify family groups. Additionally, recording practices at Cafcass have improved over time, this has increased the availability of demographic information of all those involved, as well as child's final legal outcome. Data access Researchers can apply to the Secure Anonymised Information Linkage databank (SAIL) for access to the Cafcass pseudonymised administrative data extract, where it is refreshed bi-annually. Keywords children, out of home care, family relations, family law.

Phenotyping congenital anomalies in administrative hospital records. Paediatr Perinat Epidemiol 2020; 34:21-28. [PMID: 31960476 PMCID: PMC7003968 DOI: 10.1111/ppe.12627] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/14/2019] [Revised: 10/27/2019] [Accepted: 11/07/2019] [Indexed: 01/06/2023]
Abstract
BACKGROUND Congenital anomalies are a major cause of co-morbidity in children. Diagnostic code lists are increasingly used to identify congenital anomalies in administrative health records. Evidence is lacking on comparability of these code lists. OBJECTIVES To compare prevalence of congenital anomalies and prognostic outcomes for children with congenital anomalies identified in administrative health records using three different code lists. METHODS We developed national cohorts of singleton livebirths in England (n = 7 354 363, 2003-2014) and Scotland (n = 493 556, 2003-2011). Children with congenital anomalies were identified if congenital anomaly diagnosis was recorded at birth, during subsequent hospital admission or as cause of death before 2 years old. We used three code lists: the EUROCAT list for congenital anomaly surveillance in Europe; the Hardelid list developed to identify children with chronic conditions (including congenital anomalies) admitted to hospital in England; and the Feudtner list developed to indicate children with complex chronic conditions (including congenital anomalies) admitted to hospitals in the United States. We compared prevalence, and risks of postnatal hospital readmission and death according to each code list in England and Scotland. RESULTS Prevalence of congenital anomalies was highest using the EUROCAT list (4.1% of livebirths in England, 3.7% in Scotland), followed by Hardelid (3.1% and 3.0% of livebirths, respectively) and Feudtner (1.8% and 1.5% of livebirths, respectively). 67.2%-73.3% of children with congenital anomalies in England and 65.2%-77.0% in Scotland had at least one postnatal hospital admission across the three code lists; mortality ranged between 42.6-75.4 and 41.5-88.7 deaths per 1000 births in England Scotland, respectively. The risk of these adverse outcomes was highest using Feudtner and lowest using EUROCAT code lists. CONCLUSIONS The prevalence of congenital anomalies varied by congenital anomaly code list, over time and between countries, reflecting in part differences in hospital coding practices and admission thresholds. As a minimum, researchers using administrative health data to study congenital anomalies should report sensitivity analyses using different code lists.

Maternal adversity and variation in the rate of children entering local authority care during infancy in England: a longitudinal ecological study. Int J Popul Data Sci 2019.

Abstract
BackgroundIn England, the rate at which infants enter care varies considerably by local authority, with little evidence on what drives these differences. Decisions instigating infant entry into care may be triggered by child protection concerns arising from parental ill-health or risky behaviour from pregnancy onwards.
Main AimWe explored the extent to which adversity indicated within women’s hospitalisation history, pre-delivery, explained differences in rate of infant entry into care between local authorities.
Methods/ApproachCombining data from several sources (Office for National Statistics Population Estimates, Public Health England Fingertips, 2011 Census, Children Looked After Return, and Hospital Episode Statistics), we derived population-level predictors for entry into care (i.e. local case-mix) for 131 English local authorities from 2006/07 to 2013/14. Our primary outcome was rate of infant entry into care. We used linear mixed-effects models to analyse the relationship between the outcome and percentage of live births with maternal history of adversity-related hospital admissions (i.e. any admission indicating substance misuse, mental ill-health, or violence, up to 36 months pre-delivery), adjusting for other case-mix measures.
ResultsRate of infant entry into care (mean: 85.16 per 10,000 [min-max: 0.00-318.51]) and percentage of live births with maternal history of adversity-related hospital admissions (4.62%, [0.52-16.19%]) varied greatly by local authority. Prevalence of maternal adversity accounted for 24% of variation in rate of entry (95% CI: 14-35%). After adjustment, there was evidence that a percentage point increase in prevalence of maternal adversity - both over time and between local authorities - is associated with an extra 2.56 infants, per 10,000, entering care (1.31-3.82).
Conclusion Prevalence of maternal adversity prior to birth helps to explain differing rates of infant entry into care among local authorities. Further research using individual-level linked parent-child data is required to ascertain whether interventions to reduce maternal adversity before birth would decrease rate of infant entry into care.

Long-term mortality in mothers of infants with neonatal abstinence syndrome: A population-based parallel-cohort study in England and Ontario, Canada. PLoS Med 2019; 16:e1002974.

Abstract
BACKGROUND Opioid addiction is a major public health threat to healthy life expectancy; however, little is known of long-term mortality for mothers with opioid use in pregnancy. Pregnancy and delivery care are opportunities to improve access to addiction and supportive services. Treating neonatal abstinence syndrome (NAS) as a marker of opioid use during pregnancy, this study reports long-term maternal mortality among mothers with a birth affected by NAS in relation to that of mothers without a NAS-affected birth in 2 high-prevalence jurisdictions, England and Ontario, Canada. METHODS AND FINDINGS We conducted a population-based study using linked administrative health data to develop parallel cohorts of mother-infant dyads in England and Ontario between 2002 and 2012. The study population comprised 13,577 and 4,966 mothers of infants with NAS and 4,205,675 and 929,985 control mothers in England and Ontario, respectively. Death records captured all-cause maternal mortality after delivery through March 31, 2016, and cause-specific maternal mortality to December 31, 2014. The primary exposure was a live birth of an infant with NAS, and the main outcome was all deaths among mothers following their date of delivery. We modelled the association between NAS and all-cause maternal mortality using Cox regression, and the cumulative incidence of cause-specific mortality within a competing risks framework. All-cause mortality rates, 10-year cumulative incidence risk of death, and crude and age-adjusted hazard ratios were calculated. Estimated crude 10-year mortality based on Kaplan-Meier curves in mothers of infants with NAS was 5.1% (95% CI 4.7%-5.6%) in England and 4.6% (95% CI 3.8%-5.5%) in Ontario versus 0.4% (95% CI 0.41%-0.42%) in England and 0.4% (95% CI 0.38%-0.41%) in Ontario for controls (p < 0.001 for all comparisons). Survival curves showed no clear inflection point or period of heightened risk. The crude hazard ratio for all-cause mortality was 12.1 (95% 11.1-13.2; p < 0.001) in England and 11.4 (9.7-13.4; p < 0.001) in Ontario; age adjustment did not reduce the hazard ratios. The cumulative incidence of death was higher among NAS mothers than controls for almost all causes of death. The majority of deaths were by avoidable causes, defined as those that are preventable, amenable to care, or both. Limitations included lack of direct measures of maternal opioid use, other substance misuse, and treatments or supports received. CONCLUSIONS In this study, we found that approximately 1 in 20 mothers of infants with NAS died within 10 years of delivery in both England and Canada-a mortality risk 11-12 times higher than for control mothers. Risk of death was not limited to the early postpartum period targeted by most public health programs. Policy responses to the current opioid epidemic require effective strategies for long-term support to improve the health and welfare of opioid-using mothers and their children.

Abstract
IntroductionOpioid-use during pregnancy is indicative of future adversity for mothers and children. We aimed to investigate neonatal abstinence syndrome (NAS) as a marker of drug-use in pregnancy and to compare maternal all-cause mortality relative to those with infants born without NAS in two high prevalence jurisdictions; England and Ontario.
Objectives and ApproachWe developed two parallel cohorts using linked mother-baby records for all births in hospitals in England and Ontario between 2002 and 2013. Mothers with opioid-use were identified based on NAS recorded in the baby’s record. Maternal mortality within 10 years of delivery was compared for mothers with and without a NAS-pregnancy. The association between opioid-use in pregnancy and all-cause mortality was modelled using Cox regression. In addition, we estimated the unadjusted cumulative incidence of cause-specific mortality within a competing risks framework. Harmonised clinical codes were used to define all exposures, outcomes and comorbidities.
ResultsThe study population comprised 13,581 and 4,966 NAS mothers in England and Ontario, respectively. Controls totalled 4,205,941 for England and 929,985 for Ontario. The crude hazard ratios for all-cause mortality were 12.1 (95% CI; 11.1-13.2) for England and 11.4 (9.7, 13.4) for Ontario, which were attenuated to 9.8 (9.0-10.6) and 9.0 (7.6, 10.7) respectively, after adjustment for maternal age at delivery and Charlson comorbidity index. The cumulative incidence of death was much higher among NAS mothers than controls for all causes except cancer in the English cohort, where estimates were similar. The majority of deaths within the NAS group were attributable to avoidable causes, particularly reflecting unintentional injuries (cumulative incidence of 19.6 (16.6-23.1) for England and 13.9 (9.7-19.3) for Ontario).
Conclusion/ImplicationsOur approach demonstrates the utility of mother-baby record linkage to examine long-term health outcomes of vulnerable families. We identified similarly high mortality rates among the mothers of NAS babies in both England and Ontario, indicating a need for public health programs to target support to mothers as well and infants.

Maternal mortality of women with opioid-use during pregnancy in England: investigating bias in a cohort of linked mother-baby hospital records. Int J Popul Data Sci 2018.

Abstract
IntroductionOpioid-addiction is a major public health threat, with rates of drug misuse related deaths increasing in North America and England. Linkage within and between administrative data datasets is important for capturing determinants and outcomes but this vulnerable population is highly susceptible to linkage error, which can result in inaccurate estimates.
Objectives and ApproachWe investigated neonatal abstinence syndrome (NAS) as a marker of opioid-use in pregnancy, using linked mother-baby records to identify maternal opioid-use based on NAS in the baby’s record. Maternal all-cause mortality was compared for mothers with and without a NAS-pregnancy. Bias was assessed through comparison of linked and unlinked NAS baby characteristics. De-identified national hospital inpatient data – including postcode-district and GP surgery-code – were used for deterministic and probabilistic linkage of mothers and babies born in England 2002-2013. Linked national mortality data captured maternal deaths
ResultsLinkage between maternal and baby records was possible for 96% of all live births in England, but for only 88% of study/cohort babies with NAS (n=18,087). NAS babies with unlinked records represented a more vulnerable population with longer hospital stay (median 12 versus 7 days, p<0.001), low birthweight (44% <2500g versus 27%, p<0.001) and discharge to social services (13% versus 8%, p<0.001) than NAS babies who could be linked to maternal records. Non-linkage may plausibly be driven by mismatching or missing identifiers reflecting adoption and out-of-home care arrangements for the baby, potentially also indicating greater maternal adversity. Within the linked cohort (comparing 13,581 women with a NAS baby and 4,205,941 women without a NAS baby), the crude hazard ratio for all-cause mortality was 12.1 (11.1-13.2).
Conclusion/ImplicationsReview of unlinked records suggests evidence of linkage bias, with the implication that our results may underestimate the risk of death among women with opioid-use. Complementary linkages, drawing on other data - such as birth records where the mother is named - could help address non-linkage driven by out-of-home care.

Abstract
IntroductionCerebral palsy (CP) is a complex condition that can manifest in different ways and is likely to be under-recorded in primary care databases. As identification based only on diagnostic codes will underestimate the incidence of cerebral palsy, an approach is needed to use all available information to identify more cases.
Objectives and ApproachWe used a machine-learning approach to identify likely CP cases in the Clinical Practice Research Datalink (CPRD), a UK primary-care database: i) we selected potential codes (symptoms, therapies and managements) to identify CP cases by comparing relative frequencies of codes associated with known cases versus non-cases; ii) codes with higher discriminative ability were further selected using a Random Forest method based on a resampled, balanced population; iii) we calculated the predictive score for each patient employing the discriminative ability of selected codes; and iv) manually reviewed the full medical records of likely cases (i.e. patients with higher predictive score).
ResultsPrimary care records were available for 343,199 young people aged 2000 were identified as likely cases (n=365, 0.1% of previously non-cases). Their full medical records in CPRD were manually reviewed by experts and 85 children (23.3% of likely cases) were validated as CP cases additional to the 341 initially identified by diagnostic codes, resulting in a 20% increase of CP cases.
Conclusion/ImplicationsData-driven schemes, such as the machine learning methods applied here, have the potential of identifying the most informative predictors in a cost-effective and rapid way to identify likely CP cases or other complex medical conditions in primary care database.

Abstract
IntroductionSeveral studies have shown that a short birth interval is associated with increased risks of adverse perinatal outcomes (e.g.: preterm birth, stillbirth) and neonatal and maternal death. It is unclear whether this relationship is likely to be causal or to reflect confounding due to psychosocial vulnerability.
Objectives and ApproachTo determine the association between birth interval for mothers with and without indicators of vulnerability.
Using Hospital Episode Statistics for England, we included mothers with a live birth in 2011. Vulnerability indicators were codes for mental health problems, adversity related injury (ARI), material or social disadvantage (M/SD) recorded in admissions in the previous five years, or age
Time (in days) to next delivery within five years was analysed using Cox proportional hazard regression models and adjusted for maternal age, parity, multiple and preterm birth.
ResultsOf 636,876 women delivering in 2011, 93,266 (14.6\%) had indicators of vulnerability: 63,421 (10.0%) for mental health problems, 8,229 (1.2%) for an ARI, 21,616 (3.4%) for M/SD, and 32,622 (5.1%) were teenage mothers.
Over a third of mothers (242,401; 38.1%) had another live birth within five years. Median time to next delivery was 957 days (5-95% centiles: 433-1694), and was longest for teenage mothers (979 days, 391-1726), and shortest for women with ARIs (904 days, 391-1697).
Vulnerable mothers were more likely than women with no vulnerability indicators to have another live birth (HRadj: 1.13, 95%CI: 1.12-1.14): risks were independently increased for teenage mothers (HRadj: 1.53, 1.50-1.55), women with an ARI (HRadj: 1.15, 1.11-1.19) or mental health problems (HRadj: 1.05, 1.03-1.06).
Conclusion/ImplicationsVulnerable mothers had a shorter subsequent birth interval and an increased risk of birth in the next five years. Maternity care may be an appropriate time to target interventions to vulnerable families to enable choice about timing of subsequent pregnancy.

Abstract
BackgroundEarly identification of child adversity (comprising abuse, neglect, social or material adversity) is essential to target early interventions to safeguard children, and support vulnerable families. We determined the prevalence of indicators of adversity recorded in diagnostic codes in child and/or maternal hospital admissions in England.
Data SourceAll birth admissions recorded in the NHS in England in 2011, and subsequent admissions up to 5 years old, linked to maternal records from 1 year before to up to 5 years after delivery.
MethodsPrevalence of adversity indicators in child and/or maternal admission records that reflect adversity-related injury (ARI), or social or material adversity (SMA).
ResultsAmong 646,956 live born children, 2.6% (95% CI: 2.6 to 2.7) had at least one adversity indicator by <5 years (0.8% ARI, 2.6% SMA). Cumulative prevalence was 1.1% in children aged <6 months, 1.2% in children aged <1 year, 2.1% by <=2 years, and 2.6% up to 5 years old. Combined prevalence in maternal and/or child records will be presented.
ConclusionTo inform health policy, clinical and prognostic significance of adversity indicators requires evaluation through linkage to health and welfare outcomes.

ResultsWe included 636,876 women, of whom 93,266 (14.6%) had indicators of vulnerability: 63,421 (10.0%) for mental health problems, 8,229 (1.2%) for ARI, 21,616 (3.4%) for MSD, and 32,622 (5.1%) were aged <20y.
Over a third of mothers (242,401; 38.1%) had another live birth. Median birth interval was 957 days (5-95%centiles:433- 1694), and was shortest for women with ARIs (904 days,391- 1697).
Vulnerable mothers were more likely than women with no vulnerability indicators to have another live birth (HRadj:1.13, 95%CI:1.12-1.14), particularly teenage mothers (HRadj:1.53,1.50-1.55).
ConclusionsVulnerable mothers had a shorter subsequent birth interval and were more likely to have another birth in the next five years. Maternity care may be an appropriate time to target interventions to vulnerable families to enable choice about timing of subsequent pregnancy.

Child mortality in England compared with Sweden: a birth cohort study. Lancet 2018; 391:2008-2018. [PMID: 29731173 PMCID: PMC5958228 DOI: 10.1016/s0140-6736(18)30670-6] [Citation(s) in RCA: 51] [Impact Index Per Article: 8.5] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/01/2017] [Revised: 02/27/2018] [Accepted: 03/09/2018] [Indexed: 11/16/2022]
Abstract
BACKGROUND Child mortality is almost twice as high in England compared with Sweden. We aimed to establish the extent to which adverse birth characteristics and socioeconomic factors explain this difference. METHODS We developed nationally representative cohorts of singleton livebirths between Jan 1, 2003, and Dec 31, 2012, using the Hospital Episode Statistics in England, and the Swedish Medical Birth Register in Sweden, with longitudinal follow-up from linked hospital admissions and mortality records. We analysed mortality as the outcome, based on deaths from any cause at age 2-27 days, 28-364 days, and 1-4 years. We fitted Cox proportional hazard regression models to estimate the hazard ratios (HRs) for England compared with Sweden in all three age groups. The models were adjusted for birth characteristics (gestational age, birthweight, sex, and congenital anomalies), and for socioeconomic factors (maternal age and socioeconomic status). FINDINGS The English cohort comprised 3 932 886 births and 11 392 deaths and the Swedish cohort comprised 1 013 360 births and 1927 deaths. The unadjusted HRs for England compared with Sweden were 1·66 (95% CI 1·53-1·81) at 2-27 days, 1·59 (1·47-1·71) at 28-364 days, and 1·27 (1·15-1·40) at 1-4 years. At 2-27 days, 77% of the excess risk of death in England was explained by birth characteristics and a further 3% by socioeconomic factors. At 28-364 days, 68% of the excess risk of death in England was explained by birth characteristics and a further 11% by socioeconomic factors. At 1-4 years, the adjusted HR did not indicate a significant difference between countries. INTERPRETATION Excess child mortality in England compared with Sweden was largely explained by the unfavourable distribution of birth characteristics in England. Socioeconomic factors contributed to these differences through associations with adverse birth characteristics and increased mortality after 1 month of age. Policies to reduce child mortality in England could have most impact by reducing adverse birth characteristics through improving the health of women before and during pregnancy and reducing socioeconomic disadvantage.
