Can a simple score predict appendicitis better than a scan?
NCT ID NCT07804238
First seen Sep 04, 2026 ยท Last updated Sep 04, 2026
Summary
Researchers are comparing three bedside scoring systems, the Alvarado, AIR, and AAS, to see which one most accurately identifies acute appendicitis in adults. The study reviews records of 300 emergency patients who had their appendix removed due to suspected appendicitis. Each patient's score is calculated from symptoms, exam findings, and lab results, then checked against the final tissue diagnosis. The goal is to find the most reliable tool to guide decisions and cut down on unnecessary operations.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- What this could lead to
- If one scoring system proves clearly better, hospitals could adopt it to diagnose appendicitis more accurately, reducing unnecessary surgeries and speeding up care.
- What could go wrong
- This is a retrospective review of past records, not a controlled experiment. The scores are calculated after the fact, and results may not apply to other hospitals or populations.
