Patient education is a key component for the management of many acute and chronic conditions. Presentation to the emergency department (ED) may offer an opportunity for patient education. The purpose of this review was to explore and analyze the type of interventions and outcomes used in this setting and to determine whether there is emerging evidence of effectiveness of these interventions. This systematic review was guided by an explicit search strategy, retrieval procedures, and appraisal process. An initial search was done using the key words "emergency" and "patient education." Data sources included articles published between 1966 and 2005. Synthesis tables were created using Weston and Cranton's adaptation of Bloom's Taxonomy of Learning Domains as a framework. Nineteen studies met the inclusion criteria and comprised the final set for this review. Interventions used lecture, discussion, demonstration, and practice and instructional tools to relay information. Outcome measures included those from cognitive, affective, and psychomotor learning domains. In 10 randomized controlled trials, 6 studies reported being able to meet their learning domain outcomes using a variety of teaching methods. Educational interventions in the ED are both possible and feasible as examined in the studies in this review.
