Key result
The use of the modified Alvarado score (≥7) did not significantly reduce the overall negative appendectomy rate compared to surgeon's choice (14% vs 20%, p=0.488).
Why the study?
Does the modified Alvarado score reduce the rate of negative appendectomies compared to surgeon's clinical judgment in patients with suspected acute appendicitis?
Does the modified Alvarado score reduce the rate of negative appendectomies compared to surgeon's clinical judgment in patients with suspected acute appendicitis?
Absolute Event Rate: 14% vs 20%
p-value: p=0.488
The modified Alvarado score does not significantly reduce the rate of negative appendectomies compared to clinical judgment alone.

Does not support routine Modified Alvarado use to curb negative appendectomies; leaves open need for randomized validation before adoption.
Munir et al. (2008) studied Acute appendicitis (n=60). Modified Alvarado score ≥ 7 vs. Surgeon's choice was evaluated on Negative appendectomy rate (p=0.488). The use of the modified Alvarado score (≥7) did not significantly reduce the overall negative appendectomy rate compared to surgeon's choice (14% vs 20%, p=0.488).
