Have you ever wondered where WikEM get’s all of its awesome algorithm diagrams? They’re from ddxof (differential diagnosis of), our newest WikEM social media partner. Ddxof contains a compilation of cases based on real patients, each inspiring a systematic approach to the evaluation and management of their chief complaint or diagnosis. The format is centered around the development of simplified algorithms targeted to emergency physicians, with a focus on intelligibility, utility and reproducibility. The new ddxof: algorithm browser also allows for quick searching and filtering by categories/tags among the 60+ and growing algorithms and diagrams. Check it out!
