ABSTRACT Children and young people who live in out-of-home care (OoHC) can display aggressive behaviours when their emerging self-regulation and executive functioning systems are overwhelmed. Consequently, their carers can experience incidents that may cause some carers’ ongoing stress symptoms. Early intervention with occupational health supports is important; however, including a specific trauma treatment such as Eye-Movement Desensitisation and Reprocessing (EMDR) is unusual. EMDR supports the resolution of stress symptoms and helps carers promote a stable home environment. Stability contributes to calm home environments and incident reduction. The purpose of this mixed methods study was to better understand the inclusion of EMDR into a workforce wellbeing model and explore changes in incident numbers in houses, staff retention, and time-loss injury. Interviews with senior managers and focus groups with therapeutic practitioners from two Australian states were conducted. Descriptive statistics for administrative data were calculated after a quantitative audit. Several programs including EMDR and occupational health policies were working towards enhanced workplace safety. A reduction in the monthly average incident rate from 11.9 (2019–2020) to 6.9 (2022–2023) was identified. Offering an effective treatment to staff that promotes wellbeing, retention, and stability in care homes may be a critically important policy recommendation for organisations with staff at risk of traumatic incidents. IMPLICATIONS Eye -Movement Desensitisation and Reprocessing (EMDR) is an effective trauma therapy that works for residential out-of-home care staff. EMDR enhances carers’ emotional wellbeing and capacity when working with the young people in their care. More stable relationships between carers, children, and young people can lead to reductions in stressful workplace incidents and a more stable workforce.
