Patient education prior to discharge from hospital is a practice developed under the name of "discharge education" (DE) in the Anglo-Saxon countries. This new form of patient education targets acute and sometimes chronic patients and concerns all hospital specialties ; it aims to facilitate the transition "hospitalhome" and avoid early readmissions. In this article we want to outline a framework of indications and effects of DE, starting from an analysis of the international literature, and identify its quality criteria in order to forecast the conditions of its application to our context. A scoping review allowed us to examine 43 scientific studies specifically related to the description, analysis and evaluation of discharge education, as well as some recommendations. Almost half of the studies are published in Nursing Science journals. DE is an intense and short educational intervention (30 minutes to an hour) delivered mainly in acute situations. Paediatrics has the largest number of publications together with post-operative care. In most studies, DE is effective in improving clinical and psychosocial parameters, reducing early admissions, increasing skills and patient compliance. To achieve its goals, DE must be structured and include systematic follow up. Focused on the patient's needs and his learning ability, it uses a specific interactive pedagogy to which caregivers must be trained. The analysis of the international research leaves no doubt about the positive contributions of DE. It would be important for caregivers and policymakers to look at it as an opportunity to improve the quality of care and to humanize it.
