Background: The Safer Households initiative, adapted from the SafeWards model, seeks to promote calmer, safer and more connected environments in residential aged care. Grounded in Uniting’s Household Model of Care, the program was piloted to assess its utility in supporting relational care approaches that enhance emotional safety and reduce distress and aggression. Methods: A mixed‑methods process evaluation was conducted across three sites, guided by the Model for Adaptation Design and Implementation (MADI), the Consolidated Framework for Implementation Research (CFIR), and RE‑AIM. Data sources included interviews with staff and residents, audits of training materials, implementation diaries, and analysis of routinely collected indicators, including incident data, Quality of Care Experience (QCE), and Quality of Life (QoL). Results: Implementation varied across sites. One site adopted a champion‑led coaching model and another a structured committee‑based approach; both supported cultural shifts toward calmer, kinder care environments. Staff reported improved teamwork and communication, while residents described feeling more respected and emotionally secure. Routine data indicated early signs of improvement in QCE, though no consistent changes were observed in QoL or incident rates at this stage. Implementation at the third site was limited due to competing priorities. Conclusions: Safer Households appears feasible and valued when supported by strong leadership, visible champions and adaptable resources. Embedding the model within induction, supervision and quality systems may enhance sustainability. Findings highlight the potential of relational approaches to improving emotional safety and wellbeing in residential aged care, with further implementation needed to understand sustainability across diverse settings.
