This study aimed to examine whether an action research approach was effective in reducing the isolation of staff in 2 residential aged care facilities, within the context of an evidence-informed falls prevention program. A Falls Action Research Group comprising 12 nursing/nonnursing staff across 2 residential aged care facilities was established and engaged in critical dialogue and action over 12 months to improve their fall prevention activities. Through the group members' engagement, a research community was established that diminished staff isolation by engaging members in a sustained process of collaboration around falls prevention, which worked to disrupt occupational silos and challenge traditional staff hierarchies.
