Your clinical impression (or "gestalt") about a patient's acuity is both critical and difficult to train. gistalt was designed to make it fun! Your goal playing gistalt is to accurately identify which patients are sick (requiring hospitalization or immediate interventions for stabilization) or not-sick (conditions that can be safely treated with outpatient follow-up). gistalt games are simple and fun. You'll start with a stack of patient presentations including vital signs, laboratory results and imaging. Swipe each card left (for not-sick) or right (for-sick) to see the next question. At the end of the stack, review your responses and see your score. Your gistalt score specially gauges your ability to detect the most critically-ill patients and institute the treatments that will make a difference. New questions are added regularly and don't require an app update.
