The Chief Complaint

How would you like to walk into the ER confident that you knew what to do, no matter what comes through the door? 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?
