Trends of paediatric head injury and acute care costs in Australia

Sports-related traumatic brain injuries and acute care costs in children

OBJECTIVE

To estimate traumatic brain injuries (TBIs) and acute care costs due to sports activities.

METHODS

A planned secondary analysis of 7799 children from 5 years old to <18 years old with head injuries enrolled in a prospective multicentre study between 2011 and 2014. Sports-related TBIs were identified by the epidemiology codes for activity, place and injury mechanism. The sports cohort was stratified into two age groups (younger: 5-11 and older: 12-17 years). Acute care costs from the publicly funded Australian health system perspective are presented in 2018 pound sterling (£).

RESULTS

There were 2903 children (37%) with sports-related TBIs. Mean age was 12.0 years (95% CI 11.9 to 12.1 years); 78% were male. Bicycle riding was associated with the most TBIs (14%), with mean per-patient costs of £802 (95% CI £644 to £960) and 17% of acute costs. The highest acute costs (21%) were from motorcycle-related TBIs (3.8% of injuries), with mean per-patient costs of £3795 (95% CI £1850 to £5739). For younger boys and girls, bicycle riding was associated with the highest TBIs and total costs; however, the mean per-patient costs were highest for motorcycle and horse riding, respectively. For older boys, rugby was associated with the most TBIs. However, motorcycle riding had the highest total and mean per-patient acute costs. For older girls, horse riding was associated with the most TBIs and highest total acute costs, and motorcycle riding was associated with the highest mean per-patient costs.

CONCLUSION

Injury prevention strategies should focus on age-related and sex-related sports activities to reduce the burden of TBIs in children.

Cost-effectiveness of patient observation on cranial CT use with minor head trauma

OBJECTIVE

To evaluate the cost-effectiveness of planned observation on cranial CT use in children with minor head trauma.

DESIGN

Planned secondary analysis of a multicentre prospective observation study.

SETTING

Australia and New Zealand.

PATIENTS

An analytic cohort of 18 471 children aged <18 years with Glasgow Coma Scale scores 14-15 presenting <24 hours after blunt head trauma stratified by the Pediatric Emergency Care Applied Research Network (PECARN) traumatic brain injury (TBI) risk categories.

INTERVENTION

A plan for observation and immediate CT scan were documented after the initial assessment. The planned observation group included those with planned observation and no immediate plan for CT.

MAIN OUTCOME MEASURES

Taking an Australian public-funded healthcare perspective, we estimated the cost-effectiveness of planned observation on the adjusted mean costs per child and CT use reduction by net benefit regression analysis using ordinary least squares with robust SEs and bootstrapping. All costs presented in 2018 euros.

RESULTS

Planned observation in 4945 (27%) children was cost-saving of €85 (95% CI -120 to -51) with 10.4% lower CT use (95% CI 9.6 to 11.2). This strategy was cost-saving for the PECARN high-risk (-€757 (95% CI -961 to -554)) and intermediate-risk (-€52 (95% CI -99 to -4.3)) categories, with 43% (95% CI 39 to 47) and 11% (95% CI 9.6 to 12.4) lower CT use, respectively. The very low-risk category incurred more cost of €86 (95% CI 67 to 104) with planned observation and 0.05% lower CT use (95% CI -0.61 to 0.71).

CONCLUSION

Planned ED observation in selected children with minor head trauma is cost-effective for reducing CT use for the PECARN intermediate-risk and high-risk categories.
