The Chief Complaint app uses an algorithmic approach to over 50 of the most common complaints encountered in emergency medicine. Never feel lost or overwhelmed again, not knowing what the next step in the work-up is. Not sure what tests to order or if the patient can go home? The Chief Complaint helps you answer all those questions and more!
