Costs for physical and mental health hospitalizations in the first 13 years of life among children engaged with Child Protection Services.

BACKGROUND

Longitudinal data on health costs associated with physical and mental conditions are not available for children reported to child protection services.

OBJECTIVE

To estimate the costs of hospitalization for physical and mental health conditions by child protection status, including out-of-home-care (OOHC) placement, from birth until 13-years, and to assess the excess costs associated with child protection contact over this period.

PARTICIPANTS AND SETTING

Australian population cohort of 79,285 children in a multi-agency linkage study.

METHODS

Costs of hospitalization were estimated from birth (if available) using Round 17, National Hospital Cost Data Collection (2012-13; deflated to 2015-16 AUD). Records of the state child protection authority determined contact status. Data were reported separately for children in OOHC. Hospital separations were classified as mental disorder-related if the primary diagnosis was recorded in ICD-10 Chapter V (F00-F99).

RESULTS

Hospital separations were more common in children with child protection contact. Physical health care costs per child decreased with age for all children, but were significantly higher for children with contact. Mental health costs per child were always significantly higher for children with contact, with marked increases at 3 ≤ 4 years and 8 ≤ 9 years. Point estimates of annual costs per child were always highest for children with an OOHC placement. The net present value of the excess costs was $3,224 per child until 13- years, discounted at 5 %.

CONCLUSIONS

Children in contact with child protection services show higher rates and costs for physical and mental health hospitalizations in each of their first 13 years of life.
