The goal of this year-long project was to design an open source tool which would support patients in effective transition out of psychiatric inpatient care. Transition Toolkit is a system designed to introduce clinicians to the potential that open source tools can provide in terms of accessible and customisable alternatives to commercial tools. Run over two workshops, the model incentivises patients to begin their discharge planning earlier in their care, while reframing how it is viewed, taking away some of the pressure and making it fun and collaborative. The designed outcome comprises customisable 3D printed figurines, cards and an online guide for clinicians which help implement the system.
