Thanks PSL team. A restorative approach considers safety systems as made of people and relationships as well as rules and processes. You can check out a brief summary here that is specific to mental health settings. https://www.hqsc.govt.nz/blog/using-a-restorative-approach-to-respond-to-adverse-events/
Learning reviews are also much better than RCA as they focus on storytelling and appreciate context (assuming there is a safe space to speak up and be heard. )
