The AIR score was developed to overcome some of the drawbacks of the Alvarado score, another diagnostic scoring system for identifying appendicitis. [2] The AIR score is one of the two scores (the other being the Adult Appendicitis Score , AAS) recommended by the 2020 World Society of Emergency Surgery clinical practice guidelines for the ...
Alvarado scoring has largely been superseded as a clinical prediction tool by the Appendicitis Inflammatory Response score. [ 2 ] [ 3 ] [ 4 ] Also known by the mnemonic MANTRELS, the scale has 6 clinical items (3 signs and 3 symptoms ) and 2 laboratory measurements, each given an additive point score, with a maximum of 10 points possible.
