ARCHETYPE Appendicitis Inflammatory Response (AIR) Score (openEHR-EHR-OBSERVATION.air_score.v0)

ARCHETYPE IDopenEHR-EHR-OBSERVATION.air_score.v0
ConceptAppendicitis Inflammatory Response (AIR) Score
DescriptionTool to assist the diagnosis and prediction of severity of suspected acute appendicitis.
Use

Use to assist the diagnosis and prediction of severity of suspected acute appendicitis.

AIR is an acronym for Appendicitis Inflammatory Response and consists of seven components, each contributing points to the total score generating an estimated probability as well as a recommendation based on the risk level;

  • Vomiting 0-1
  • Pain in right inferior fossa 0-1
  • Rebound tenderness or muscular defense 0-3
  • Body temperature ≥38.5 0-1
  • Neutrophils 0-2
  • White blood cell count 0-2
  • CRP 0-2

The tool has a maximum score of 12 points, and the result is associated with one of three categories estimating probability along with a recommendation on appropriate action;
Sum 0-4 - low probability. Consider outpatient follow-up if unaltered general condition.
Sum 5-8 - indeterminate group. Consider in-hospital active observation with rescoring and/or further examination in accordance with local tradition.
Sum 9-12 - high probability. Consider surgical exploration.

PurposeTo assist the diagnosis and prediction of severity of suspected acute appendicitis.
