British Society of Paediatric Dentistry: A policy document on dental neglect in children.

The British Society of Paediatric Dentistry's (BSPD) first policy document on dental neglect was published online in 2009. It proposed a new original definition of dental neglect, discussed the identification of dental neglect and recommended adopting a tiered response, with three stages of intervention according to level of concern. Furthermore, it detailed how the dental team should both contribute to the child protection process and implement wider measures to safeguard and promote children's welfare. Since 2009, these concepts have been widely adopted in the UK and beyond. Furthermore, there have been significant advances in both research and practice. Policy documents produced by the BSPD represent a majority view, based on the consideration of currently available evidence, and are tailored to a UK working environment. Although this updated document's recommendations remain broadly unchanged, this version reflects the professions' progress in understanding dental neglect and minor updates to terminology and, following a consultation process, has been amended to address the needs of two main audiences-dental professionals and nondental health and social care professionals-in order to enhance interdisciplinary working.

Adolescence as the Context for Understanding Young Mothers' Engagement with Health Promotion: A Phenomenological Exploration.

BACKGROUND: The current social construction of young mothers is generally negative, pointing to a lack of engagement with universal services and poor outcomes for their infants and children. However, qualitative studies offer an alternative, more positive construct of young motherhood. Understanding the context of young motherhood can improve the relevance and efficacy of health promotion directed to this group of high-risk mothers. AIM: To explore the lived experience of young women transitioning to motherhood to better understand their experiences and perspective; and what influences their engagement with health promotion aimed to support safer parenting practices and whether their behaviour changes over time with exposure to parenting health promotion. METHOD: Longitudinal Interpretative Phenomenological Analysis (IPA) was used with five first-time mothers identified with characteristics known to influence poorer outcomes for infants and children such as low educational achievement and economic disadvantage. Participants aged 16 to 19 years were recruited antenatally. Serial in-depth interviews were conducted at three time points during the ante- and post-natal periods. Interviews were transcribed and data were analysed inductively following the prescribed method of double hermeneutic analysis for IPA. FINDING: Three themes were identified from the full study: Transition, Information, and Fractured application; the focus of this paper is Transition. Transition revealed that becoming mothers impacted key adolescent developmental tasks; their identity and relationships were significantly affected, both positively and negatively and adolescent brain development influenced behaviour and decision making capability. Adolescence influenced how these young mothers engaged with and interpreted parenting health promotion messages. CONCLUSIONS: Young mothers in this study operate within the context of adolescence. Adolescence impacts participants' decision making activity and early parenting behaviours which informs the debate on why young mothers may fail to reduce risks for their infants. This insight can contribute to the development of more effective health promotion/educational strategies, and support professionals to better engage with this high-risk group to improve early parenting behaviour and subsequently improve outcomes for their infants and children.

Common factors in serious case reviews of child maltreatment where there is a medical cause of death: qualitative thematic analysis.

AIM: To identify the common factors in serious case reviews (SCRs) where a child has died of a medical cause. DESIGN: Qualitative thematic analysis. BACKGROUND: SCRs take place when neglect or abuse results in children dying or being seriously harmed. Known key factors within SCRs include parental substance misuse, mental health problems and domestic abuse. To date, there has been no investigation of children who die of a medical cause where there are concerns about child maltreatment. DATA SOURCES: A list of SCRs relating to deaths through medical causes was provided from previous coded studies and accessed from the National Society for the Prevention of Cruelty to Children National Case Review Repository. Twenty-three SCRs with a medical cause of death from 1 April 2009 to 31 March 2017 were sourced. RESULTS: 20 children died of an acute condition and 12 of a chronic condition; 20 of the deaths were unexpected and maltreatment contributed to the deaths of 18 children. Most children were aged either <1 year or >16 years at the time of death. Many parents were caring for a child with additional vulnerabilities including behavioural issues (6/23), learning difficulties (6/23), mental health issues (5/23) or a chronic medical condition (12/23). Common parental experiences included domestic violence/abuse (13/23), drug/alcohol misuse (10/23), mental ill health or struggling to cope (7/23), criminal history (11/23) and caring for another vulnerable individual (8/23). Most children lived in a chaotic household characterised by missed medical appointments (18/23), poor school attendance (11/23), poor physical home environment (7/23) and disguised compliance (12/23). All 23 SCRs reported elements of abusive or neglectful parenting. In most, there was an evidence of cumulative harm, where multiple factors contributed to their premature death. At the time of death, 11 children were receiving social care support. CONCLUSION: Although the underlying medical cause of the child's death was often incurable, the maltreatment that often exacerbated the medical issue could have been prevented.

Classification of sleep-related sudden unexpected death in infancy: A national survey.

AIM: To identify how British Child Death Overview Panels (CDOPs) and paediatric pathologists classify cause of death for sleep-related Sudden Unexpected Death in Infancy (SUDI). To determine compliance with national requirements for SUDI investigation. METHODS: Electronic survey of CDOPs and pathologists using three vignettes of SUDI cases illustrating: accidental asphyxia, typical Sudden Infant Death Syndrome (SIDS) and SIDS with co-sleeping. RESULTS: Thirty-eight (41%) of 92 CDOPs returned questionnaires, and 32 were complete. Thirteen (14%) of 90 pathologists returned complete questionnaires. Thirty-one (97%) CDOPs and 7 (53%) pathologists agreed with the cause of death in the accidental asphyxia case; 24 (75%) CDOPs and 9 (69%) pathologists in the typical SIDS case; and 11 (34%) CDOPs and 1 (8%) pathologist in the co-sleeping SIDS case. Pathologists used the terms SUDI or unascertained as the cause of death for the accidental asphyxia case (46%) and the co-sleeping SIDS case (77%). These terms were used by CDOPs for the typical SIDS case (25%) and the co-sleeping SIDS case (41%). Seventeen (46%) CDOPs reported compliance with guidelines for investigation in more than 75% of cases. CONCLUSION: There is wide variation in classification of deaths, with only limited agreement between CDOPs and pathologists. The terms SIDS and accidental asphyxia are underused, even in typical cases.

Quality of investigations into unexpected deaths of infants and young children in England after implementation of national child death review procedures in 2008: a retrospective assessment.

OBJECTIVES: In 2008, new statutory national procedures for responding to unexpected child deaths were introduced throughout England. There has, to date, been no national audit of these procedures. STUDY DESIGN: Families bereaved by the unexpected death of a child under 4 years of age since 2008 were invited to participate. Factors contributing to the death and investigations after the death were explored. Telephone interviews were conducted, and coroners' documents were obtained. The nature and quality of investigations was compared with the required procedures; information on each case was reviewed by a multiagency panel; and the death was categorised using the Avon clinicopathological classification. RESULTS: Data were obtained from 91 bereaved families (64 infant deaths and 27 children aged 1-3 years); 85 remained unexplained after postmortem examination. Documentation of multiagency assessments was poorly recorded. Most (88%) families received a home visit from the police, but few (37%) received joint visits by police and healthcare professionals. Postmortem examinations closely followed national guidance; 94% involved paediatric pathologists; 61% of families had a final meeting with a paediatrician to explain the investigation outcome. There was no improvement in frequency of home visits by health professionals or final meetings with paediatricians between 2008-2013 and 2014-2017 and no improvement in parental satisfaction with the process. CONCLUSIONS: Statutory procedures need to be followed more closely. The implementation of a national child mortality database from 2019 will allow continuing audit of the quality of investigations after unexpected child deaths. An important area amenable to improvement is increased involvement by paediatricians.

National child death review statutory and operational guidance: Key concepts for practising paediatricians.

In October 2018, National Health Service England published new operational guidance for reviewing child deaths, which covers all children who die less than 18 years of age regardless of the cause of death. The Guidance is for all healthcare professionals caring for children as well as senior leaders who commission, provide or regulate children's services. It does not aim to be prescriptive but instead sets out a framework of expectations that intends to be flexible and proportionate. Its essential building blocks will be familiar to practising paediatricians: notification, investigation, review and reporting. It should be regarded as a key pillar in the hospital's governance program.

Sudden infant death syndrome (SIDS) and the routine otoacoustic emission infant hearing screening test: an epidemiological retrospective case-control study.

OBJECTIVES: To investigate whether decreased otoacoustic emission (OAE) signal recordings in the right ear are associated with an increased risk of sudden infant death syndrome (SIDS) and to monitor any temporal changes in risk factors. DESIGN: Retrospective case-control study. SETTING: Telephone interviews with families recruited in England between July 2016 and October 2017 who experienced the unexpected death of a child <4 years old since 2008 and control families recruited from maternity wards in Bristol and Birmingham. PARTICIPANTS: We recruited 91 (89%) of the 102 bereaved families who made initial contact, 64 deaths were under 1 year (sudden unexpected death in infancy) of which 60 remained unexplained (SIDS). Of the 220 control families, 194 (88%) follow-up interviews were conducted. We had analysable hearing data for 24 SIDS infants (40%) and 98 controls (51%). RESULTS: OAE signals were marginally increased rather than decreased among SIDS infants for the right ear, especially at lower frequencies, but not significantly so. The strongest predictors of SIDS were bed-sharing in hazardous (infant sleeping next to a carer who smoked, drank alcohol or slept on a sofa) circumstances (35% vs 3% controls, p<0.0001), infants found prone (33% vs 3% controls, p<0.0001) and infants whose health in the final week was 'not good' (53% vs 9% controls, p<0.0001). The prevalence of maternal smoking during pregnancy among both SIDS mothers (20%) and controls (10%) was much lower than previous studies. CONCLUSIONS: Hearing data were difficult to obtain; larger numbers would be needed to determine if asymmetrical differences between the right and left ear were a marker for SIDS. A national prospective registry for monitoring and a renewed campaign to a new generation of parents needs to be considered underlining the initial message to place infants on their backs for sleep and the more recent message to avoid bed-sharing in hazardous circumstances.

Self-awareness following a traumatic brain injury in childhood: a developmental perspective.

Impaired self-awareness is a common consequence following a brain injury that affects engagement in rehabilitation and results in poor long term functional outcomes. Literature regarding self-awareness following a brain injury in childhood is lacking. The aim of this research study was to understand the self-awareness of deficits from a developmental perspective. METHODS: A multiple case study design with fully integrated mixed methodology (QUAN+QUAL). Fifteen children/young people (CYP) with traumatic brain injury (TBI) (5-17 years; 10 male) were recruited and data were collected from CYP, their parents and teachers. Self-report measures included Strengths and Difficulties Questionnaire and Harter Scales. Interview measures included Self-Understanding Interview and Knowledge Interview for Children. A novel method of analysis compared CYP report to parent/teacher report and to normative children's data. Three exemplars showcase this methodology. RESULTS: Within-case and cross-case analysis identified interrupted development of self-awareness following TBI. CYP ratings differed most from parent/teacher ratings in the social and behavioural domains. In relation to the school/learning and physical domains, CYP ratings differed most from normative children's data. The younger children had greater degree of ratings discrepancy across all domains. Seven key themes were aspirations, beliefs, being different, brain injuries, characteristics, participation, and interpersonal interactions and relationships. CONCLUSION: This study is among the first to describe the complexity of self-awareness across a range of functional domains following a brain injury in childhood. New theoretical and clinical perspectives are presented from understanding the importance of typical development and the child's age at injury.

Qualitative analysis of serious case reviews into unexpected infant deaths.

OBJECTIVE: To develop a detailed understanding of the circumstances of sudden unexpected death in infancy (SUDI) cases subject to serious case review (SCR). DESIGN: This was a thematic analysis of SCRs relating to cases of SUDI in England. SCRs were obtained for SUDI cases dying between 1 April 2011 and 31 March 2014. These were cases (aged 0-2 years) that presented as a SUDI and for which no clear medical or forensic cause of death was found. RESULTS: SCRs were held for 30 SUDI cases, published reports were available for 27/30. The median (range) age at death was 2 (0-19) months. Background risk factors in families included: alcohol or drug dependency in 18/27, parental mental health problems in 14/27, domestic abuse in 9/27 and parental criminal records in 13/27. Nineteen infants had received support from social care, 10/19 were subject to child protection plans. Neglect was a feature in 15/27 cases. Parents did not engage with professionals in 18/27 cases, involving social care in 14/18, health care in 13/18 and drug and substance misuse services in 5/18. Eighteen of 27 deaths occurred in highly hazardous sleep environments, 16/18 involved cosleeping and 13/16 cosleeping deaths occurred with parents who were intoxicated with alcohol or impaired by drugs. CONCLUSION: Most SUDI cases occurred in hazardous sleep environments and are potentially preventable. They occurred in families well known to services with concerns about neglect, substance misuse and poor engagement. More consideration is needed on how best to support such vulnerable families.

Maternal filicide in a cohort of English Serious Case Reviews.

A national mixed-methods study of English Serious Case Reviews (SCRs) was carried out to better understand the characteristics and circumstances of maternally perpetrated filicides, to compare these with paternally perpetrated cases, and to identify learning points for mental health professionals. Published reports for all SCRs of children in England dying as a result of abuse or neglect from 2011 to 2014 were subject to qualitative analysis using a system of layered reading and inductive thematic analysis, along with descriptive and comparative quantitative analysis. There were 86 deaths directly attributable to child maltreatment within the immediate family. The mother was the suspected perpetrator in 20. Twelve of the mother perpetrators were victims of domestic violence, while 15 of the father perpetrators were known to be perpetrators of domestic violence. Those deaths resulting from impulsive violence or severe, persistent cruelty are almost exclusively perpetrated by males, while those with an apparent intent to kill the child are slightly more likely to be perpetrated by mothers. Four key themes were identified through the qualitative analysis: domestic violence, maternal mental illness, separation and maternal isolation, and the invisibility of the child. These findings highlight the important role of domestic violence and its interaction with maternal mental health. Professionals working with mothers with mental health problems need to adopt a supportive but professionally curious stance, to be alert to signs of escalating stress or worsening mental ill-health, and to provide supportive and accessible structures for at-risk families.

The Child Abuse Potential Inventory: Development of an Arabic version.

The Child Abuse Potential Inventory (CAPI) is a well-validated screening tool for assessing potential for child physical abuse, and has been translated into many different languages. To date the CAPI has not been translated into Arabic or used in any studies in Arabic-speaking populations. This study reports on the process of adapting the CAPI into Arabic Language which was undertaken following the International Society of Pharma-economics and Outcomes Research (ISPOR) guidelines. The translation/adaptation process was multi-stage, and involved the use of a Delphi process, cognitive debriefing, back translation, and a pilot testing of the Arabic CAPI at two primary health care centers with a population of pregnant women (n=60). Following "literal translation" 73 out of the 160 items needed re-phrasing to adapt the items to the Oman context. No differences were found when comparing results of the translated or back-translated versions to source; however, eight items needed further amendment following translated to back-translated comparison and feedback from the pilot. Iterations were resolved following in-depth interviews. Discrepancies were due to differences in culture, parenting practices, and religion. Piloting of the tool indicated mean score value of 155.8 (SD=59.4) and eleven women (18%) scored above the cut off value of 215. This Arabic translation of the CAPI was undertaken using rigorous methodology and sets the scene for further research on the Arabic CAPI within Arabic-speaking populations.

Rigour and Rapport: a qualitative study of parents' and professionals' experiences of joint agency infant death investigation.

BACKGROUND: In many countries there are now detailed Child Death Review (CDR) processes following unexpected child deaths. CDR can lead to a fuller understanding of the causes for each child's death but this potentially intrusive process may increase the distress of bereaved families. In England, a joint agency approach (JAA) is used where police, healthcare and social services investigate sudden child deaths together and a key part of this is the joint home visit (JHV) where specialist police and paediatricians visit the home with the parents to view the scene of death. This study aimed to learn of bereaved parents' experiences of JAA investigation following Sudden Unexpected Death in Infancy (SUDI). METHODS: This was a qualitative study of joint agency investigation of SUDI by specialist police, healthcare and social services including case note analysis, parental questionnaires, and in-depth interviews with parents and professionals. Families were recruited at the conclusion of the JAA. Data were analysed using a Framework Approach. RESULTS: 21/113 eligible families and 26 professionals participated giving theoretical saturation of data. There was an inherent conflict for professionals trying to both investigate deaths thoroughly as well as support families. Bereaved parents appreciated the JAA especially for the information it provided about the cause of death but were frustrated with long delays waiting to obtain this. Many parents wanted more emotional support to be routinely provided. Most parents found the JHV helpful but a small minority of mothers found this intensely distressing. In comparison to JHVs, when police visited death scenes without paediatricians, information was missed and parents found these visits more upsetting. There were issues with uniformed non-specialist police traumatising parents by starting criminal investigations and preventing parents from accessing their home or collecting vital possessions. CONCLUSIONS: Overall most parents feel supported by professionals during the JAA; however there is scope for improvement. Paediatricians should ensure that parents are kept updated with the progress of the investigations. Some parents require more emotional support and professionals should assist them in accessing this.

Unintentional asphyxia, SIDS, and medically explained deaths: a descriptive study of outcomes of child death review (CDR) investigations following sudden unexpected death in infancy.

BACKGROUND: A comprehensive child death review (CDR) program was introduced in England and Wales in 2008, but as yet data have only been analyzed at a local level, limiting the learning from deaths. The aim of this study is to describe the profile of causes and risk factors for sudden unexpected death in infancy (SUDI) as determined by the new CDR program. METHODS: This was a descriptive outcome study using data from child death overview panel Form C for SUDI cases dying during 2010-2012 in the West Midlands region of England. The main outcome measures were: cause of death, risk factors and potential preventability of death, and determination of deaths probably due to unintentional asphyxia. RESULTS: Data were obtained for 65/70 (93 %) SUDI cases. 20/65 (31 %) deaths were initially categorized as due to medical causes; 21/65 (32 %) as SIDS; and 24/65 (37 %) as undetermined. Reanalysis suggested that 2/21 SIDS and 7/24 undetermined deaths were probably due to unintentional asphyxia, with 6 of these involving co-sleeping and excessive parental alcohol consumption. Deaths classified as "undetermined" had significantly higher total family and environmental risk factor scores (mean 2.6, 95 % CI 2.0-3.3) compared to those classified as SIDS (mean 1.6, 95 % CI 1.2-1.9), or medical causes for death (mean 1.1, 95 % CI 0.8-1.3). 9/20 (47 %) of medical deaths, 19/21 (90 %) SIDS, and 23/24 (96 %) undetermined deaths were considered to be potentially preventable. There were inadequacies in medical provision identified in 5/20 (25 %) of medically explained deaths. CONCLUSIONS: The CDR program results in detailed information about risk factors for SUDI cases but failed to recognize deaths probably due to unintentional asphyxia. The misclassification of probable unintentional asphyxial deaths and SIDS as "undetermined deaths" is likely to limit learning from these deaths and inhibit prevention strategies. Many SUDI occurred in families with mental illness, substance misuse and chaotic lifestyles and most in unsafe sleep environments. This knowledge could be used to better target safe sleep advice for vulnerable families and prevent SUDI in the future.

Parental understanding and self-blame following sudden infant death: a mixed-methods study of bereaved parents' and professionals' experiences.

OBJECTIVES: Improvements in our understanding of the role of modifiable risk factors for sudden infant death syndrome (SIDS) mean that previous reassurance to parents that these deaths were unpreventable may no longer be appropriate. This study aimed to learn of bereaved parents' and healthcare professionals' experiences of understanding causes of death following detailed sudden unexpected death in infancy (SUDI) investigations. The research questions were: How do bereaved parents understand the cause of death and risk factors identified during detailed investigation following a sudden unexpected infant death? What is the association between bereaved parents' mental health and this understanding? What are healthcare professionals' experiences of sharing such information with families? DESIGN: This was a mixed-methods study using a Framework Approach. SETTING: Specialist paediatric services. PARTICIPANTS: Bereaved parents were recruited following detailed multiagency SUDI investigations; 21/113 eligible families and 27 professionals participated giving theoretical saturation of data. DATA COLLECTION: We analysed case records from all agencies, interviewed professionals and invited parents to complete the Hospital Anxiety and Depression Scale (HADS) and questionnaires or in-depth interviews. RESULTS: Nearly all bereaved parents were able to understand the cause of death and several SIDS parents had a good understanding of the relevant modifiable risk factors even when these related directly to their actions. Paediatricians worried that discussing risk factors with parents would result in parental self-blame and some deliberately avoided these discussions. Over half the families did not mention blame or blamed no one. The cause of death of the infants of these families varied. 3/21 mothers expressed overwhelming feelings of self-blame and had clinically significant scores on HADS. CONCLUSIONS: Bereaved parents want detailed information about their child's death. Our study suggests parents want health professionals to explain the role of risk factors in SIDS. We found no evidence that sharing this information is a direct cause of parental self-blame.

'Tweaking' the model for understanding and preventing maternal and neonatal morbidity and mortality in Low Income Countries: "inserting new ideas into a timeless wine skin".

BACKGROUND: Maternal and neonatal morbidity and mortality in Low Income Countries, especially in sub-Saharan Africa involves numerous interrelated causes. The three-delay model/framework was advanced to better understand the causes and associated Contextual factors. It continues to inform many aspects of programming and research on combating maternal and child morbidity and mortality in the said countries. Although this model addresses some of the core areas that can be targeted to drastically reduce maternal and neonatal morbidity and mortality, it potentially omits other critical facets especially around primary prevention, and pre- and post-hospitalization continuum of care. DISCUSSION: The final causes of Maternal and Neonatal mortality and morbidity maybe limited to a few themes largely centering on infections, preterm births, and pregnancy and childbirth related complications. However, to effectively tackle these causes of morbidity and mortality, a broad based approach is required. Some of the core issues that need to be addressed include:-i) prevention of vertically transmitted infections, intra-partum related adverse events and broad primary prevention strategies, ii) overall health care seeking behavior and delays therein, iii) quality of care at point of service delivery, and iv) post-insult treatment follow up and rehabilitation. In this article we propose a five-pronged framework that takes all the above into consideration. This frameworks further builds on the three-delay model and offers a more comprehensive approach to understanding and preventing maternal and neonatal morbidity and mortality in Low Income Countries CONCLUSION: In shaping the post 2015 agenda, the scope of engagement in maternal and newborn health need to be widened if further gains are to be realized and sustained. Our proposed five pronged approach incorporates the need for continued investment in tackling the recognized three delays, but broadens this to also address earlier aspects of primary prevention, and the need for tertiary prevention through ongoing follow up and rehabilitation. It takes into perspective the spectrum of new evidence and how it can be used to deepen overall understanding of prevention strategies for maternal and neonatal morbidity and mortality in LICS.

Deaths in children with epilepsies: a UK-wide study.

PURPOSE: This UK-wide review of deaths in children with epilepsies was undertaken to ascertain any demographic, clinical, organisational, or management factors associated with the deaths, and to determine the extent to which any of these may have deviated from nationally agreed best practice. METHOD: Paediatricians across the UK were asked to notify any deaths in children with epilepsies over a 10-month period. Hospital and community case notes were reviewed by pairs of case assessors using a structured assessment tool combining holistic and criterion-based approaches. RESULTS: Of 46 deaths notified, case notes were obtained on 33. The majority of children had associated developmental impairments. The majority (24), died of an associated co-morbidity rather than of epilepsy. Seven died of convulsive status epilepticus and seven as sudden unexpected deaths in epilepsy. Twenty four percent of deaths were judged to be preventable; potentially modifiable factors included fragmentation of care, support for families, and recognition of and response to acute illness in the child, including the appropriate management of prolonged seizures. CONCLUSIONS: Although this audit has demonstrated significant improvements in quality of care when compared with the last national audit of epilepsy deaths in 2002, further improvement is still required.

International comparison of sudden unexpected death in infancy rates using a newly proposed set of cause-of-death codes.

BACKGROUND: Comparing rates of sudden unexpected death in infancy (SUDI) in different countries and over time is difficult, as these deaths are certified differently in different countries, and, even within the same jurisdiction, changes in this death certification process have occurred over time. AIMS: To identify if International Classification of Diseases-10 (ICD-10) codes are being applied differently in different countries, and to develop a more robust tool for international comparison of these types of deaths. METHODS: Usage of six ICD-10 codes, which code for the majority of SUDI, was compared for the years 2002-2010 in eight high-income countries. RESULTS: There was a great variability in how each country codes SUDI. For example, the proportion of SUDI coded as sudden infant death syndrome (R95) ranged from 32.6% in Japan to 72.5% in Germany. The proportion of deaths coded as accidental suffocation and strangulation in bed (W75) ranged from 1.1% in Germany to 31.7% in New Zealand. Japan was the only country to consistently use the R96 code, with 44.8% of SUDI attributed to that code. The lowest, overall, SUDI rate was seen in the Netherlands (0.19/1000 live births (LB)), and the highest in New Zealand (1.00/1000 LB). SUDI accounted for one-third to half of postneonatal mortality in 2002-2010 for all of the countries except for the Netherlands. CONCLUSIONS: The proposed set of ICD-10 codes encompasses the codes used in different countries for most SUDI cases. Use of these codes will allow for better international comparisons and tracking of trends over time.

An evidence-based guide to the investigation of sudden unexpected death in infancy.

PURPOSE: Many countries now have detailed investigations following sudden unexpected death in infancy (SUDI) but there is no clear evidence as to the most effective way to investigate SUDI. This systematic literature review addresses the following questions: What are the current models of practice for investigating SUDI? What is the evidence to support these investigative models? What are the key factors for effective SUDI investigation? METHODS: This was a systematic review of papers from Europe, North America, and Australasia, detailing models of SUDI investigation or the outcomes of SUDI investigations. RESULTS: The review includes data detailing four different models of investigation: police-led, coroner or medical examiner-led, healthcare-led or joint agency approach models. There were 18 different publications providing evidence of effectiveness of these models. All models, with the exception of police-led models, have the potential to reach best practice standards for SUDI investigation. Key factors identified for effective SUDI investigation include the need for mandatory investigation, strong leadership, integration with coronial services, and for investigations to be provided by specialist professionals. CONCLUSION: Detailed SUDI investigation should lead to greater understanding of why infants die and should help prevent future deaths. The challenge is now to ensure that local SUDI investigative practices are as effective as possible.
