Background:
Diagnostic checklists have been demonstrated to reduce errors in clinical reasoning. Building on previous validation studies, this research presents the development and clinical application of an etiology-based diagnostic framework for evaluating acute abdominal pain. The framework integrates a structured checklist of abdominal pain etiologies with a process-oriented diagnostic strategy, aiming to enhance diagnostic accuracy and clinical outcomes. This approach also serves as a potential model for the creation of diagnostic tools applicable to other symptom complexes encountered in emergency medicine.
Methods:
A cognitive task analysis (CTA) was conducted with participation from five emergency medicine experts employing a think-aloud methodology. The experts described their diagnostic reasoning processes and queried relevant clinical data to extract foundational diagnostic principles. Based on these findings, a checklist categorizing etiologies of abdominal pain was constructed, drawing from anatomical and diagnostic considerations. The clinical utility of the checklist was evaluated through its application to a representative complex case.
Results:
The diagnostic checklist was organized into five principal etiological categories: local organ disorders, diseases of adjacent organs, systemic diseases, psychogenic disorders, and gynecological conditions. Its implementation facilitated the accurate identification of atypical acute renal infarction in a diagnostically challenging case, enabling prompt clinical intervention.
Conclusions:
CTA provides a robust method for modeling expert diagnostic reasoning and supports the development of structured, etiology-based diagnostic tools. This framework enhances diagnostic precision for individuals presenting with acute abdominal pain in emergency settings and may inform the development of similar tools for other clinical presentations.

Acute pancreatitis is characterized by rapid inflammation of the pancreas, often caused by factors like gallstone blockage or excessive alcohol consumption. Chronic pancreatitis, on the other hand, is a slow, progressive inflammation that may result from long-term alcohol abuse, obstructions in the pancreatic duct, or genetic factors.
The causes of acute pancreatitis include:
