In the few past years, the approach “milieu de vie” (AMV) has gained popularity since it represents an interesting avenue to improve the quality of life of people living in long-term care homes. Despite its relevancy, the AMV is still not fully integrated in the daily practice of nursing homes. In 2014, only a handful of these homes differed from the others, regarding this approach. Many factors can explain this situation such as the obstacles that health professionals face when carrying out their tasks, staff shortage, a greater workload and the conceptual basis of the AMV which does not seem to be fully understood by many people. At the organizational level, despite a political will to transform long-term care homes, they are still run with a more institutional reasoning centered on offering care. To overcome these difficulties, certain recent conceptual developments in health promotion, such as the model of AMV of Poland & Dooris (2010), could be used to improve the AMV in long-term care homes.
