Appropriateness of diagnosis and orientation of 996 consecutive patients admitted in an emergency department with flow-based organization.

Background: Recent data, focused on the inability to transfer emergency patients to inpatient beds, has shown this to be the single most important factor contributing to overcrowding. Our Emergency Department (ED) was reorganized in the year 2000 based on the optimization of patients' flow. In this model, the emergency team had to refer patients to units fitting best to their condition with minimal delays.
