Association of Child Maltreatment With Risk of Death During Childhood in South Australia

Receipt of parenting, disability, unemployment, and other income support payments in persons aged 16 to 33 years - the associations with child maltreatment

BACKGROUND

Child maltreatment (CM) is a major public health concern with life-long effects. Its impact on income support has rarely been studied.

OBJECTIVE

To examine the association between CM and receipt of income support payments and the budgetary impact for persons 16 to 33 years.

PARTICIPANTS AND SETTING

A South Australian birth cohort, born 1986 to 2004 (n = 339,411).

METHODS

We linked child protection (CP) administrative records with national welfare payment records, ending March 2020. Receipt of income support payments and mean payment amounts were described by CP contact (adjusted for child and family attributes). Budget impact was modelled at the national level.

RESULTS

Adjusted odds ratio (AOR) for receipt of any income support payment was 3.01 (2.95-3.07) for individuals with any CP contact versus no CP contact. Among those receiving any payment, adjusted annualised mean benefit payment was $3754 (US$1446) among individuals with no CP contact, $6262 (US$4,307) in persons with any CP contact, and $9,747 in persons who'd been in OOHC. Cumulative payments modelled from age 16 to 33 years totalled $38,570 (US$26,652) for individuals with no CP contact, and $181,743 (US$125,003) for individuals who'd been in OOHC. Modelled for the Australian population to age 33, the extra cost associated with CP contact added 39 % to the government income support budget.

CONCLUSION

CM is strongly associated with receipt of income support payments. Investment in effective preventive and protective strategies for CP involved children could address this core social determinant of health, while providing budget savings.

Nonaccidental Pediatric Trauma: Which Traditional Clues Predict Abuse?

OBJECTIVES

The objective of this study is to determine which of the child abuse clues quoted in the literature predict nonaccidental trauma (NAT): history incongruent with injuries found on examination or imaging, old injuries present, history of trauma denied by caregivers, multiple fractures present, changing history, fractures of varied duration, metaphyseal fracture, ear bruise, neck bruise, different history (second historian), and metaphyseal fracture.

METHODS

This is a 4-year retrospective study of all suspected NAT cases referred to our medical center. In addition to the index visit, medical records were searched for visits before the index visit with patient historical or physical findings that might have suggested NAT but were not investigated. The association of diagnostic clues and the outcome were assessed by chi-square and logistic regression analysis.

RESULTS

For 48 months, there were 109 cases of suspected NAT referred for evaluation (age range, 1 week to 15 years). After formal investigation by an abuse specialist, 79.3% of the cases were considered "likely abuse". Those historical or physical findings with a univariate association with a final conclusion of likely abuse included history incongruent with injuries, old injuries present, trauma history denied, changed history, and retinal hemorrhage. In multivariate logistic regression, only a history incongruent with injures remained an independent predictor of likely abuse (odds ratio, 8.65; 95% confidence interval, 1.74-43.07; P = 0.0151). After review of prior records, in only 2 of 109 cases (1.8%) was there a prior visit where NAT could have been suspected; however, history was thought to be congruent with the injury at the original visits.

CONCLUSION

In this 4-year study of NAT, the clinical clue that best predicted likely abuse after expert investigation was a history that was incongruent with the injuries found on emergency department evaluation. The incidence of possible early recognition from a prior emergency department visit in this group was very low, <2% of cases.

Child protection system involvement in children of incarcerated mothers: A linked data study

BACKGROUND

Women prisoners are a growing portion of the prison population. Health and social outcomes of their children have been studied and found to be poor, but little is known about child protection outcomes.

OBJECTIVES

Ascertain child protection system contact of children exposed to maternal incarceration.

PARTICIPANTS AND SETTING

All children born between 1985 and 2011 exposed to the incarceration of their mothers in a Western Australian correctional facility and a matched comparison group.

METHODS

A matched cohort study using linked administrative data on 2637 mothers entering prison between 1985 and 2015 and their 6680 children. We estimated hazard ratios (HRs) and incidence rate ratios (IRRs) of child protection service (CPS) contact post maternal incarceration (four concern levels), comparing rates for children exposed to maternal incarceration with a matched non-exposed group, adjusting for maternal and child factors.

FINDINGS

Exposure to maternal incarceration increased risk of CPS contact. Unadjusted HRs exposed vs unexposed children were 7.06 (95%CI = 6.49-7.69) for substantiated child maltreatment and 12.89 (95%CI = 11.42-14.55) for out-of-home care (OOHC). Unadjusted IRRs were 6.04 (95%CI = 5.57-6.55) for number of substantiations and 12.47 (95%CI = 10.65-14.59) for number of removals to OOHC. HRs and IRRs were only slightly attenuated in adjusted models.

CONCLUSIONS

Maternal incarceration is a warning flag for a child at high risk of serious child protection concerns. Family-friendly rehabilitative women's prisons, incorporating support for more nurturing mother-child relationships could provide a placed-based public health opportunity for disrupting distressing life trajectories and intergenerational pathways of disadvantage of these vulnerable children and their mothers. This population should be a priority for trauma-informed family support services.

Typical median effective radiation doses using an anthropomorphic bone fracture phantom for initial radiographic skeletal surveys in the investigation of suspected physical abuse

BACKGROUND

A series of 31 radiographs is recommended by the Royal College of Radiologists (RCR) when investigating suspected physical abuse (SPA).

OBJECTIVE

To determine the radiation dose delivered for skeletal surveys performed for SPA in Victorian radiology departments based on their local protocols.

MATERIALS AND METHODS

A 5-year-old paediatric bone fracture phantom was radiographed at five radiology sites using both the RCR recommended protocol and, where applicable, the local departmental SPA protocol. The radiation doses were measured and recorded. These were scaled down to estimate the effective radiation doses for a 2-year-old child at each site and the associated radiation risks estimated.

RESULTS

The median effective dose for all radiographic projections in the RCR skeletal survey radiographic series was 0.09 mSv. The estimated risk of radiation-induced cancer and radiation-induced death from cancer for 2-year-old children is classified as "very low," with girls having a higher risk than boys.

CONCLUSION

The median effective radiation dose for the RCR skeletal survey for imaging in SPA was 0.09 mSv resulting in a "very low" additional risk of radiation-induced cancer. The authors will now aim to ascertain whether whole-body CT skeletal survey can replace the radiographic series for imaging in SPA while maintaining a comparable radiation dose.

Excess hospital costs incurred by individuals with child abuse and neglect history in South Australia: A birth-cohort study

Child abuse and neglect is a serious public health issue across the globe, with documented impacts on health, but the impact on hospital costs, at the population level, is unknown. We aimed to estimate the additional public hospital costs for emergency department visits and admitted patient hospitalizations, for persons with reported child protection concerns, from birth to 31 years and modelled to age 65. Using linked hospital data from 2003 to 2017 for a population birth-cohort of all individuals born in South Australia from 1986 to 2017, we estimated costs of public hospital care. Mean cost and cost differences (adjusted and unadjusted) in 2018 Australian dollars (AU$) were calculated for persons with child protection contact vs none, per person and at the population level. Persons with child protection contact had higher annualized mean hospital costs than those with no contact, with cost differentials increasing with age. Unadjusted differential cost per person was AU$338 (95% CI AU$204-AU$473) from birth to 12 years; increasing to AU$2242 (AU$2074-AU$2411) at ages 25 to 31 years, equating to an additional AU$124 (US$100) million for public hospital services from birth to 31 years, an 18% cost penalty (33% from 13 to 31 years). Modelled to age 65 years, excess costs were estimated at AU$415 (US$337, adjusted: AU$365 and US$296) million, a 27% cost impost. There is a considerable hospital cost penalty associated with persons with reported child protection concerns, especially from adolescence into adulthood, highlighting an opportunity for cost savings by preventive investment in effective early-in-life interventions.

Child maltreatment and emergency department visits: a longitudinal birth cohort study from infancy to early adulthood

BACKGROUND

Child maltreatment (CM) is a serious global public health issue, with documented impacts on health.

OBJECTIVE

To examine the association between different levels of CM concern, and Emergency Department (ED) visits from infancy to early adulthood.

PARTICIPANTS AND SETTING

Individuals born in Adelaide, South Australia from January 1986 to June 2017 (N = 443,754).

METHODS

Using linked administrative data, we examined frequency and adjusted rate ratios for all-cause and cause specific ED visits among individuals with varying levels of CM concern.

RESULTS

Cumulative mean ED visits to age 14.5 years were higher for individuals with any CM concern, ranging from 10.2 to 14.8, compared with 6.4 in persons with no recorded CM concern. Adjusted rate ratios for ED visits varied from 1.26 (95% CI: 1.23-1.30) to 1.54 (1.48-1.60) in children (birth to 12 years), 1.98 (CI: 1.92-2.04) to 4.34 (CI: 4.09-4.60) in adolescence and 2.22 (CI: 2.14-3.48) to 3.48 (3.27-3.72) in young adults, increasing with severity of maltreatment concerns. ED visits coded as self-harm or poisoning, injuries, substance use or mental illness were particularly high, with incidence rate ratios mostly 3 to 15 times for mental health/substance related visits and 1.5 to 3.2 for other accidents or injury for individuals with any CM concern versus none.

CONCLUSIONS

The high rate ratios for ED visits in children with CM concern, especially for self-harm, substance use and mental health during adolescence and adulthood highlights the enduring mental health needs of victims of child maltreatment, providing further impetus for prevention.
