Background: Patients with atraumatic abdominal pain are common in the emergency department and have a relatively high hospital mortality, with a very wide spectrum of different causes. Rapid, goal-directed diagnosis is essential in this context.
Methods: In a Delphi process with representatives of different disciplines, a diagnostic treatment pathway was designed, which is called the Abdominal Pain Unit (APU).
Results: The treatment pathway was designed as an extended event process chain. Crucial decision points were specified using standard operating procedures.
Discussion: The APU treatment pathway establishes a consistent treatment structure for patients with atraumatic abdominal pain. It has the potential to improve the quality of care and reduce intrahospital mortality over the long term.
