AbstractBackgroundThe “ Quebec’s Homes for Older Adults with a Neurocognitive Disorder ” (QHOA) model aims to improve the quality of residential and long‐term care environments for people losing their autonomy. Considering the major paradigm shift behind the QHOA philosophy, it seemed timely to co‐construct a Living Lab‐type structural organisation whose main mission will be to contribute to the sustainability of the new model.ObjectivesSince 2021, we have been co‐constructing links between scientists, decision‐makers, staff (carers, cooks, housekeepers, etc.), QHOA stakeholders and, above all, the community and its seniors. Our structure is a Living Lab and the main objective is to cyclically and participatively co‐construct a set of solutions applicable to QHOAs. Our work will encourage the design and development of sustainable solutions by considering human (e.g., self‐determination, personalization of care), environmental (e.g., layout and design, camouflage strategies), technological (e.g., sensors, cameras, connected watches and scales, artificial intelligence, software for care and medication), work organization, and continuous training of stakeholders.ResultsThe co‐construction process involved more than 40 researchers, clinicians, decision‐makers, or stakeholders. We have all been able to delineate the structure of the Living Lab and how knowledge will be disseminated, rallied, and promoted. This presentation will resume the main steps (including successes and challenges) of our work.ImplicationsA Living Lab is a place for collaboration, exchange, and co‐creation. The actors in the field have the most relevant knowledge of the living context in which the projects will be deployed. Our intersectoral team (20 fields of expertise) will provide the scientific knowledge to ensure the sustainability and ongoing development of the QHOA model.
