This article offers a review of the literature on interprofessional education (IPE), a form of education that brings together members from two or more professions in a joint training endeavor. As part of this training, participants gain knowledge through other professionals and learn about them. The goal of IPE is to improve collaboration between health professionals and the quality of patient care. IPE is booming worldwide and seems far from a mere fad. This expansion can be explained by several factors: the increasing importance attributed to the quality of care and patient safety, care changes (aging population and an increase in chronic diseases) and the shortage of health professionals. The expectations of IPE are large, while the evidence supporting its effectiveness is in the process of being gathered.
