EMRAs EM Rashes app offers a fast, easy, and accurate way to diagnose important rashes that present most commonly to emergency departments. Based on a popular rash algorithm developed by dermatological emergency expert Dr. Heather Murphy-Lavoie and featured in Emergency Medicine magazine on the EM:Rap blog, this practical app eliminates diagnostic guesswork. By selecting a rash type, then answering a series of simple yes or no questions (Is the patient febrile?), the algorithm leads you into a narrowed differential diagnosis and overview of each disease process, including notable findings and mainstays of treatment. Developed for emergency medicine physicians by emergency medicine physicians, this simple, free application was created by Dr. Murphy-Lavoie and Dr. David Kammer to help with your daily practice.
