Interpregnancy interval and adverse birth outcomes: a population-based cohort study of twins.

BACKGROUND: To investigate associations between interpregnancy intervals (IPIs) and adverse birth outcomes in twin pregnancies. METHODS: This retrospective cohort study of 9,867 twin pregnancies in Western Australia from 1980-2015. Relative Risks (RRs) were estimated for the interval prior to the pregnancy (IPI) as the exposure and after the pregnancy as a negative control exposure for preterm birth (< 37 weeks), early preterm birth (< 34 weeks), small for gestational age (SGA: < 10th percentile of birth weight by sex and gestational age) and low birth weight (LBW: birthweight < 2,500 g). RESULTS: Relative to IPIs of 18-23 months, IPIs of < 6 months were associated with a higher risk of early preterm birth (aRR 1.41, 95% CI 1.08-1.83) and LBW for at least one twin (aRR 1.16, 95% CI 1.06-1.28). IPIs of 6-11 months were associated with a higher risk of SGA (aRR 1.24, 95% CI 1.01-1.54) and LBW for at least one twin (aRR 1.09, 95% CI 1.01-1.19). IPIs of 60-119 months and ≥ 120 months were associated with an increased risk of preterm birth (RR 1.12, 95% CI 1.03-1.22; and (aRR 1.25, 95% CI 1.10-1.41, respectively), and LBW for at least one twin (aRR 1.17, 95% CI 1.08-1.28; and aRR 1.20, 95% CI 1.05-1.36, respectively). IPIs of ≥ 120 months were also associated with an increased risk of early preterm birth (aRR 1.42, 95% CI 1.01-2.00). After negative control analysis, IPIs ≥ 120 months remained associated with early preterm birth and LBW. CONCLUSION: Evidence for adverse associations with twin birth outcomes was strongest for long IPIs.

Exposure to family and domestic violence in the prenatal period is associated with an increased risk of hospitalization for bronchiolitis in children under 2 years.

BACKGROUND: Existing research has acknowledged a correlation between stress in pregnancy and poorer respiratory health in offspring. However, research focusing on stress caused by family and domestic violence in the prenatal period is missing. METHODS: A retrospective cohort study included children born 1987-2010 who were identified as being exposed to FDV in the prenatal period (n = 1477) from two sources: WA Police Information Management System and WA Hospital Morbidity Data Collection (HMDC) and a non-exposed comparison group (n = 41 996). Hospitalization for bronchiolitis was identified in HMDC. Cox regression was used to estimate the adjusted and unadjusted hazard ratio and 95% confidence interval for bronchiolitis hospitalizations contact. RESULTS: Children exposed to FDV had a 70% (HR 1.70, 95% CI: 1.49-1.94) increased risk of hospitalization for bronchiolitis than non-exposed counterparts by age two. Children exposed to FDV had a longer average hospital stay for bronchiolitis than non-exposed children (4.0 days vs. 3.8 days, P < 0.001). CONCLUSIONS: Prenatal exposure to FDV is associated with bronchiolitis hospitalization in children <2 years. Along with other risk factors, clinicians should give consideration to maternal stress factors, including experiencing FDV as a potential contributor to bronchiolitis.

The hidden impact of alcohol on young victims: an analysis of alcohol-related police offences resulting in hospitalisation.

BACKGROUND: Alcohol-related harm (ARH) is a significant public health concern affecting young individuals, particularly those involved in alcohol-related police incidents resulting in hospitalisation. However, the impact of alcohol on young victims remains under researched. This study aimed to identify the characteristics of offenders and victims involved in these incidents, analyse the types of offences, and understand the under-ascertainment of ARH in hospital records. METHODS: A retrospective longitudinal study of 12-24-year-olds born between 1980 and 2005 was conducted using linked data from hospital admissions, emergency department presentations, and police incident records. Alcohol-related incidents were identified based on the attending officers' opinions in the Western Australia Police's Incident Management System (IMS). Logistic and log-binomial regression were utilised to analyse the factors associated with victimisation and under-ascertainment of ARH. RESULTS: Our study included 22,747 individuals (11,433 victims and 11,314 offenders) involved in alcohol-related police incidents, with a small majority of victims being female (53%, n = 6,074) and a large majority of offenders being male (84.3%, n = 9,532). Most victims did not receive a diagnosis of ARH (71%, n = 760). Women were 10 times more likely to have been a victim in ARH police incidents and 2 times more likely to have an undiagnosed alcohol-related hospital admission than men. Victims and offenders predominantly came from disadvantaged areas and major cities. Aboriginal individuals were overrepresented as both offenders and victims. A significant proportion of individuals experienced emergency department presentations or hospital admissions, with head injuries being the most common. Assault causing bodily harm was the most prevalent offence resulting in hospitalisation (66%, n = 2,018). CONCLUSIONS: There is a noteworthy disparity between the quantity of hospital admissions attributed to alcohol-related incidents and the number of cases that are formally classified as ARH in the hospital system. This disparity highlights a more profound issue of substantial under-ascertainment or inadequate identification of ARH than previously acknowledged. Our findings justify the prioritisation of prevention strategies, beyond improvement in the documentation of alcohol-related hospitalisation. Considering the scale of the problem, and the underestimation of the burden of alcohol-related hospitalisation, a proportional increase in investment is necessary to achieve population-level reductions in ARH.

The lasting impact of family and domestic violence on neonatal health outcomes.

OBJECTIVES: To compare the health of neonates born to women who experienced family and domestic violence (FDV) 12 months prior to birth, with the health of neonates born to women with an earlier history of FDV and women with no history of FDV. METHODS: A retrospective cohort of women who experienced FDV within 12 months of birth (antenatal FDV [AFDV]) (n = 1230) was identified using data from the Western Australia (WA) Police Force Incident Management System and WA Hospital Morbidity Data Collection. Two comparison cohorts were used, the first including women with a history of FDV (HFDV) 12-60 months prior to birth (n = 1549) and the second with no history of FDV (NFDV) recorded (n = 3690). Hospital, birth, mortality, and congenital anomaly data were used in generalized linear models to examine and compare neonatal health outcomes. RESULTS: Women in the AFDV group had higher proportions of factors associated with poor neonatal outcomes including smoking (42.4%), substance use (23.0%), and mental health disorders (34.8%). Neonates born to AFDV mothers had significantly higher odds of congenital anomalies (OR: 1.51, 95% CI: 1.18-1.94), low birth weight (1.74, 1.45-2.10), and preterm birth (1.48, 1.22-1.79) compared with neonates born to NFDV mother. Neonatal health outcomes in those born to AFDV women were not significantly different from those born to HFDV women. CONCLUSIONS: Antenatal and historical FDV were associated with poor neonatal health outcomes. Additional pregnancy and social support should be offered to women who have experienced FDV during or prior to pregnancy.

Epilepsy in children exposed to family and domestic violence in the first 5 years of life.

AIM: To investigate childhood (0-18 years) hospitalisation and emergency department (ED) contacts for epilepsy in Western Australian (WA) children exposed to family and domestic violence (FDV) pre 5 years of age compared to children with no FDV exposure. METHODS: A retrospective, population-based cohort study included children born 1987-2010 who were identified as being exposed to FDV (n = 7018) from two sources: WA Police Information Management System and WA Hospital Morbidity Data Collection (HMDC) and a non-exposed comparison group (n = 41 996). Epilepsy contact was identified in HMDC and ED Data Collection records. Cox regression was used to estimate the adjusted and unadjusted hazard ratio and 95% confidence interval (CI) for epilepsy contact; adjustment was made for a range of demographic characteristics known to impact health outcomes. Analyses were stratified by Aboriginal and Torres Strait Islander status to account for higher rates of FDV and epilepsy hospital admissions in Aboriginal and Torres Strait Islander children. RESULTS: Children exposed to FDV had a 62% (HR 1.62, 95% CI: 1.33-1.98) increased risk of epilepsy contact than non-exposed counterparts. Furthermore, the children exposed to FDV had a 50% longer average hospital stay for epilepsy than non-exposed children (4.7 days vs. 3 days, P = 0.006). When stratified by Aboriginal status, we found that Aboriginal children exposed to FDV stayed (on average) 2 days longer in hospital for epilepsy than their non-exposed counterparts (5.1 days vs. 3.1 days, P = 0.018). CONCLUSIONS: FDV exposure in early childhood is associated with increased risk of requiring secondary health care and longer hospital stays for childhood epilepsy.

Supporting Aboriginal and Torres Strait Islander Families to Stay Together from the Start (SAFeST Start): Urgent call to action to address crisis in infant removals.

Reducing the rate of over-representation of Aboriginal and Torres Strait Islander children in out-of-home care (OOHC) is a key Closing the Gap target committed to by all Australian governments. Current strategies are failing. The "gap" is widening, with the rate of Aboriginal and Torres Strait Islander children in OOHC at 30 June 2020 being 11 times that of non-Indigenous children. Approximately, one in five Aboriginal and Torres Strait Islander children entering OOHC each year are younger than one year. These figures represent compounding intergenerational trauma and institutional harm to Aboriginal and Torres Strait Islander families and communities. This article outlines systemic failures to address the needs of Aboriginal and Torres Strait Islander parents during pregnancy and following birth, causing cumulative harm and trauma to families, communities and cultures. Major reform to child and family notification and service systems, and significant investment to address this crisis, is urgently needed. The Family Matters Building Blocks and five elements of the Aboriginal and Torres Strait Islander Child Placement Principle (Prevention, Participation, Partnership, Placement and Connection) provide a transformative foundation to address historical, institutional, well-being and socioeconomic drivers of current catastrophic trajectories. The time for action is now.

Radiology Trainees' Perceptions of Speaking up Culture Related to Safety and Unprofessional Behavior in Their Work Environments.

OBJECTIVE. The purpose of this study was to compare radiology trainees' perceptions of the culture regarding speaking up about patient safety and unprofessional behavior in the clinical environment and to assess the likelihood that they will speak up in the presence of a medical hierarchy. MATERIALS AND METHODS. The study included radiology trainees from nine hospitals who attended a communication workshop. Trainees completed questionnaires assessing their perceptions of the support provided by their clinical environment regarding speaking up about patient safety and unprofessional behavior. We also queried their likelihood of speaking up within a team hierarchy about an error presented in a hypothetical clinical vignette. RESULTS. Of 61 participants, 58 (95%) completed questionnaires. Of these 58 participants, 84% felt encouraged by colleagues to speak up about safety concerns, and 57% felt encouraged to speak up about unprofessional behavior (p < .001). Moreover, 17% and 34% thought speaking up about safety concerns and unprofessional behavior, respectively, was difficult (p < .02). Trainees were less likely to agree that speaking up about unprofessional behavior (compared with speaking up about safety concerns) resulted in meaningful change (66% vs 95%; p < .001). In a vignette describing a sterile technique error, respondents were less likely to speak up to an attending radiologist (48%) versus a nurse, intern, or resident (79%, 84%, and 81%, respectively; p < .001). Significant predictors of the likelihood of trainees speaking up to an attending radiologist included perceived potential for patient harm as a result of the error (odds ratio [OR], 6.7; p < .001), perceptions of safety culture in the clinical environment (OR, 5.0; p = .03), and race or ethnicity (OR, 3.1; p = .03). CONCLUSION. Radiology trainees indicate gaps in workplace cultures regarding speaking up, particularly concerning unprofessional behavior and team hierarchy.

Research protocol of a multifaceted prospective mixed-method longitudinal study: Navigating Through Life - Western Australian study of transitions from out-of-home care.

BACKGROUND: Developing robust evidence is a challenge for researchers working with disadvantaged or vulnerable populations. For example, research shows that young people who have transitioned from out-of-home care (OOHC) to independent adulthood often experience poor long-term outcomes. However, evidence for the aetiology of those outcomes is weak due to methodological limitations such as small sample sizes and a lack of longitudinal data. This paper details the protocol for Navigating Through Life, a study that utilises novel research methods to better understand the pathways and outcomes of young people as they leave OOHC in Western Australia (WA). METHODS: Navigating Through Life is a longitudinal, mixed methods, population-based study. A prospective longitudinal study of young people aged 15-25 years will follow participants' experiences and outcomes over a two-year period. Quantitative and qualitative data is being collected from participants five times over 2 years, using standardised outcome measures and individual interviews. Outcome measures focus on key dimensions of young people's lives (e.g., social inclusion, well-being, resilience, self-determination). Interviews examine important influences and the variable contexts into which young people have transitioned from care. In addition, retrospective population-level data for young people transitioning from OOHC will be obtained from linked Western Australian government administrative records. Using a multitude of data sources, analysis will map pathways and outcomes of young people with care experience, and comparisons will be made with other population groups within WA. DISCUSSION: Navigating Through Life exemplifies a novel utilisation of multiple data sources to research outcomes for vulnerable and difficult to reach populations, and offers insights for other complex mixed-methods longitudinal studies. Results will provide new and more comprehensive data about specific pathways that may be influential to a range of post-care outcomes. Findings will extend evidence to inform better service-delivery models that improve outcomes and reduce disparities for vulnerable young people.

'That thing in his head': Aboriginal and non-Aboriginal Australian caregiver responses to neurodevelopmental disability diagnoses.

Little is known about the significance of cultural differences to how caregivers receive a diagnosis of neurodevelopmental disability. As part of a Fetal Alcohol Spectrum Disorder prevalence study among sentenced, detained youth, our qualitative study explored the experiences of diagnostic assessment among detained young people and their caregivers. We present findings from the perspectives of caregivers. In conversation with the sociology of diagnosis literature, we present vignettes of three Aboriginal and two non-Aboriginal caregivers' experiences of the diagnostic assessment process. We found that Aboriginal caregivers conceptualised their children's diagnosis and ongoing management in the context of their family networks and community. In contrast, non-Aboriginal caregivers focused on how the diagnosis would affect their child and interactions with various institutions including healthcare systems and schools. Caregivers' engagement with diagnostic reports and resources also followed cultural lines. Reflections on intergenerational drinking were voiced by Aboriginal caregivers, who expressed shame at receiving diagnosis. These findings advance our appreciation of cultural difference in receiving a diagnosis, the examination of which is in its nascent stages. We also suggest ways to mitigate harm from a stigmatising diagnosis and soften the well-established effects of medical dominance over the process of defining a person's capacity and status.

Disability "In-Justice": The Benefits and Challenges of "Yarning" With Young People Undergoing Diagnostic Assessment for Fetal Alcohol Spectrum Disorder in a Youth Detention Center.

Undertaking research with young people presents an array of methodological challenges. We report the findings from a qualitative study that took place alongside a fetal alcohol spectrum disorder (FASD) prevalence study among detainees in Australia. Of 38 participants, 27 were Aboriginal youth. Interviews were conducted using "social yarning" and "research topic yarning," an Indigenous research method which allows for data collection in an exploratory, culturally safe way. A complex interplay emerged between social yarning and research topic yarning which provided a space to explore responsively with participants their experiences of FASD assessments. Flexibility, including language adaptation and visual descriptions about assessments, was utilized to assist participants recall and retell their experiences. There were, however, challenges in gathering data on the assessment experiences of some participants. We describe how employing a "yarning" method for collecting data could benefit children and young people undergoing neurodevelopmental assessments in the future.

Out-of-Home Care and the Educational Achievement, Attendance, and Suspensions of Maltreated Children: A Propensity-Matched Study.

OBJECTIVE: To estimate the influence of out-of-home care on reading scores, attendance, and suspensions by comparing a matched sample of maltreated children who entered out-of-home care and maltreated children who remained at home. STUDY DESIGN: Linked administrative data for all children born in Western Australia between 1990 and 2010 was used, focusing on those with substantiated maltreatment before year 9 achievement tests (n = 3297). Propensity score modelling was used to address differences in preexisting risk factors (child, family, neighborhood characteristics, maltreatment history, and reading scores) and compare outcomes for children placed in out-of-home care and those remaining in in-home care. RESULTS: Both groups of maltreated children had poor educational outcomes. After accounting for group differences in risk characteristics, there was no difference in year 9 reading achievement for the out-of-home care and in-home care groups. There was no difference in suspensions for the groups. The only significant difference was children in out-of-home care had fewer school absences than children in in-home care. CONCLUSIONS: Out-of-home care was not found to be a significant factor in the adverse educational outcomes of these children; however, there is a clear need for further educational support to address poor outcomes for children involved with child protection services.

Maternal Mental Health and Neonatal Intensive Care Unit Discharge Readiness in Mothers of Preterm Infants.

OBJECTIVE: To evaluate associations between maternal mental health disorders (MHDs) and discharge readiness for mothers of infants born preterm (<37 weeks). We hypothesized that mothers with a history of MHDs would report decreased perceptions of neonatal intensive care unit (NICU) discharge readiness compared with mothers without a history. STUDY DESIGN: Mothers of infants born preterm in the NICU >5 days between 2012 and 2015 and participating in a transition home program completed a discharge readiness questionnaire measuring perceptions of staff support, infant well-being (medical stability), maternal well-being (emotional readiness/competency), and maternal comfort (worry about infant). Greater scores are more optimal (range 0-100). Social workers obtained a history of MHDs. Group comparisons and regression analyses were run to predict decreased scores and maternal discharge readiness. RESULTS: A total of 37% (315/850) of mothers reported a MHD. They were more likely to be white (64% vs 55% P = .05), single (64% vs 45% P ≤ .001), on Medicaid (61% vs 50% P = .002), and less likely to be non-English speaking (10% vs 22%, P ≤ .001). Mothers with MHD perceived less NICU support (92 ± 13 vs 94 ± 12, P = .005), less emotional readiness for discharge (78 ± 17 vs 81 ± 14, P = .04), and lower family cohesion (81 ± 24 vs 86 ± 19, P = .02) compared with mothers without MHD. Regression modeling (OR; CI) indicated that maternal history of MHDs predicted mother's decreased perception of infant well-being (1.56; 1.05-2.33) and her own well-being (1.99; 1.45-2.8) at discharge. CONCLUSION: One-third of mothers reported a history of MHDs. This vulnerable group perceive themselves as less ready for discharge home with their infant, indicating an unmet need for provision of enhanced transition services.

Impact of a Transition Home Program on Rehospitalization Rates of Preterm Infants.

OBJECTIVES: To evaluate the effects of a transition home program on 90-day rehospitalization rates of preterm (PT) infants born at <37 weeks gestational age implemented over 3 years for infants with Medicaid and private insurance, and to identify the impact of social/environmental and medical risk factors on rehospitalization. STUDY DESIGN: In this prospective cohort study of 954 early, moderate, and late PT infants, all families received comprehensive transition home services provided by social workers and family resource specialists (trained peers) working with the medical team. Rehospitalization data were obtained from a statewide database and parent reports. Group comparisons were made by insurance type. Regression models were run to identify factors associated with rehospitalization and duration of rehospitalization. RESULTS: In bivariable analyses, Medicaid was associated with more infants hospitalized, more than 1 hospitalization, and more days of hospitalization. Early PT infants had more rehospitalizations by 90 days than moderate (P = .05) or late PT infants (P = .01). In regression modeling, year 3 of the transition home program vs year 1 was associated with a lower risk for rehospitalization by 90 days (OR, 0.57; 95% CI, 0.36-0.93; P = .03). Medicaid (P = .04), non-English-speaking (P = .02), multiple pregnancies (P = .05), and bronchopulmonary dysplasia (P = .001) were associated with increased risk. Both bronchopulmonary dysplasia and Medicaid were associated with increased days of rehospitalization in adjusted analyses. The major cause of rehospitalization was respiratory illness (61%). CONCLUSIONS: Transition home prevention strategies must be directed at both social/environmental and medical risk factors to decrease the risk of rehospitalization.

Social Emotional Factors Increase Risk of Postpartum Depression in Mothers of Preterm Infants.

OBJECTIVE: To examine the association of maternal mental health, perceptions of readiness at neonatal intensive care unit (NICU) discharge, and social risk factors with depressive symptoms 1 month postdischarge in mothers of early (<32 weeks), moderate (32-33 weeks), and late (34-36 weeks) preterm infants. A secondary objective was to compare depressive symptoms among mothers in all preterm groups. STUDY DESIGN: Mothers (n = 734) of preterm infants cared for >5 days in the NICU and participating in a Transition Home Program completed the Fragile Infant Parent Readiness Evaluation prior to discharge for perceptions of NICU staff support, infant well-being, maternal well-being (emotional readiness/competency), and maternal comfort (worry about infant). Mental health history and social risk factors were obtained. At 1 month postdischarge the Edinburgh Postnatal Depression Scale was administered. Group comparisons and logistic regression analyses were run to predict possible depression (Edinburgh Postnatal Depression Scale ≥10). RESULTS: Mothers of early, moderate, and late preterm infants reported similar rates of possible depression (20%, 22%, and 18%, respectively) 1 month after NICU discharge. History of mental health disorder, decreased perception of maternal well-being, decreased maternal comfort regarding infant, and decreased perception of family cohesion were associated with possible depression at 1 month postdischarge. CONCLUSIONS: Mothers with a previous mental health disorder and experiencing negative perceptions of self and infant at NICU discharge were at increased risk for depressive symptomatology 1 month postdischarge regardless of infant gestational age. Comprehensive mental health assessment prior to discharge is essential to identify women at risk and provide appropriate referral.

Positive reading achievement outcomes in children who experience out-of-home care: Characteristics and predictors.

BACKGROUND: Children who enter out-of-home care ('care') are at increased risk for low academic achievement. Nonetheless, some children who have experienced out-of-home care achieve highly. Several qualitative studies of academically successful young adults with care histories have highlighted factors that may contribute to positive outcomes; however longitudinal cohort research is needed to identify characteristics and predictors of higher achieving younger children who experienced care. OBJECTIVE: To describe characteristics and circumstances of children with higher reading achievement who had entered care, and predictors of higher achievement. PARTICIPANTS AND SETTING: The study included 778 children from the Pathways of Care Longitudinal Study (POCLS) in New South Wales, Australia. METHODS: Prospective cohort data from interviews and linked administrative child protection and education data were used to identify factors associated with higher Year 3 reading achievement among Aboriginal and non-Aboriginal children that may assist in improving outcomes. RESULTS: Although a lower proportion than the general population, almost half (46 %) of children who entered care were in the higher achievement group. Higher achieving students were a diverse group and faced many adversities commonly found among children who experienced care generally. Multivariable logistic regression showed higher achievement in the cohort was significantly associated with: average or above cognitive ability, low externalizing behaviour, highly-educated carers, and non-Aboriginal students. Several supports and services were associated with higher achievement, but inconsistently across analyses. CONCLUSIONS: Results indicate potential interventions could target cognitive ability, wellbeing and environmental factors, and involve interventions directly with children and via carers to improve student outcomes.

Infants entering out-of-home care: Health, developmental needs and service provision.

BACKGROUND: There are rising numbers of infants entering out-of-home care due to child protection concerns. Research has found that infants entering care are at higher risk of developmental vulnerability and poor health problems. OBJECTIVES: To determine the prevalence of developmental vulnerability for children who entered care as infants, and the extent and likelihood of service provision in relation to their developmental vulnerability. PARTICIPANTS AND SETTING: This study includes children who entered care before the age of 1 year for the first time between May 2010 and October 2011 in New South Wales, Australia, and who received final Children's Court care and protection orders by 30 April 2013. METHODS: This is a prospective cohort study using interview data from the Pathways of Care Longitudinal Study (POCLS) as well as linked administrative child protection and health data. This study used standardised assessments (Age and Stages Questionnaire and the Brief Infant Toddler Social Emotional Assessment) included in the POCLS. Simple and multiple logistic regression analysis was conducted to investigate the likelihood of infants receiving professional services for developmental delays since placement. FINDINGS: A high proportion of children who entered care as infants were identified as developmentally vulnerable through health indicators (36 %) and standardised assessments (70 %). Only 17 % of infants in care received services for developmental delay, with 20 % and 15 % of those identified as developmentally vulnerable through standardised assessments and health-related variables receiving services, respectively. CONCLUSIONS: The findings point to the importance of developmental assessment of infants in care and the identification of developmental vulnerability and delays. The provision of early intervention services is essential for this group of high-risk infants and will be important in optimising their health, as well as social and emotional outcomes.

Hospital-Based Healthcare Workers' Experiences of Involvement in Perinatal Child Protection Processes: A Scoping Literature Review.

As the number of infants entering Out-of-Home Care at birth internationally continues to rise, Hospital-based healthcare workers (HBHCWs) are increasingly likely to become involved in ethically, morally, and legally complex child protection processes. This scoping review aimed to identify and synthesize qualitative literature pertaining to the perspectives of HBHCWs with experiences of involvement in child protection processes occurring in the perinatal period. JBI Methodology for Scoping Reviews guided this review. Databases Ovid MEDLINE, CINAHL Plus, PsycINFO, ProQuest, Web of Science, SCOPUS, and Informit were searched between March 1 and April 30, 2023. Eighteen sources were identified as meeting the criteria for inclusion following screening by two independent reviewers. Data extracted from the included sources are presented in narrative and tabular formats. Involvement in child protection processes is an inherently conflictual experience for HBHCWs and gives rise to internal, interpersonal, and interorganizational tensions. Involvement can have an enduring impact on the HBHCWs, particularly when an infant is removed from hospital by child protection authorities. Appropriate peer, managerial, and organizational level responses are essential to ameliorate risk to HBHCWs themselves and subsequently their practice with women, infants, and families. HBHCWs can provide valuable insight into the challenges of delivering healthcare at the interface of child protection. Future research should focus on building understanding of experiences across disciplines to ensure that interventions designed to prepare and support HBHCWs are effective and evidence-based.

Trajectories of homelessness and association with mental health and substance use disorders among young people transitioning from out-of-home care in Australia.

BACKGROUND: Researchers have examined sub-groups that may exist among young people transitioning from out-of-home care (OHC) using various theoretical models. However, this population group has not been examined for trajectories of homelessness risk. OBJECTIVES: To examine whether different subtypes of homelessness risk exist among young people transitioning from care and whether these trajectories of homelessness are associated with mental health and substance use disorders. PARTICIPANTS AND SETTING: A retrospective population-based cohort study was conducted from a population of 1018 young people (aged 15-18 years) who transitioned from out-of-home in 2013 to 2014 in the state of Victoria, Australia, with follow-up to 2018. METHODS: Latent Class Growth Analysis was conducted using linked data from homelessness data collections, child protection, mental health information systems, alcohol and drug use, and youth justice information systems. RESULTS: Three sub-groups of young people were identified. The 'moving on' group (88 %) had the lowest levels of homelessness, with the slope of this trajectory remaining almost stable. The 'survivors' (7 %) group started off with a high risk of homelessness, followed by a sharp decrease in homelessness risk over time. The 'complex' (5 %) group started off with a low risk of homelessness but faced sharp increases in the risk of homelessness over time. CONCLUSIONS: Our study demonstrates that subgroups of young people transitioning from care exist with distinct longitudinal trajectories of homelessness, and these classes are associated with different risk factors. Early intervention and different approaches to tackling homelessness should be considered for these three distinct groups before transitioning from care and during the first few years after leaving care.

Assessing the utility of night-time presentations as a proxy for alcohol-related harm among young emergency department trauma patients.

OBJECTIVE: To assess the usefulness of night-time presentations to measure alcohol-related harm (ARH) in young trauma patients, aged 12-24 years, attending Western Australian EDs. METHODS: A retrospective longitudinal study examined alcohol-related ED presentations in Western Australia (WA; 2002-2016) among 12- to 24-year-olds. Data from the Emergency Department Data Collection, WA State Trauma Registry Database and Hospital Morbidity Data Collection were used to identify ARH through specific codes and text searches. These were compared to ARH estimates based on presentation time. Statistical analysis involved sensitivity and specificity calculations and Cox proportional hazards modelling. RESULTS: We identified 2644 (17.8%) night-time presentations as a proxy measure of ARH among the 14 887 presentations of patients aged 12-24 years. This closely matched the 3064 (20.6%) identified as ARH through coding methods. The highest risk for an ARH presentation occurred during the night hours between 00.00 and 04.59 hours. During these hours, the risk was 4.4-5.1 times higher compared to presentations at midday (between 12.00 and 12.59 hours). However, when looking at individual patients, we observed that night-time presentations were not a strong predictor of ARH (sensitivity: 0.39; positive predictive value: 0.46). CONCLUSIONS: Implementing targeted interventions during night hours could be beneficial in addressing ARH presentations. However, relying solely on the time of presentation as a proxy for ARH is unlikely to effectively identify ARH in young individuals. Instead, the present study emphasises the importance of implementing mandatory data collection strategies in EDs to ensure accurate measurement of ARH cases.
