Key result
Combining the modified Alvarado score with ultrasonography increased the diagnostic accuracy for acute appendicitis to 97.22%, compared to 86.54% for ultrasonography alone and 78.85% for the score alone.
Why the study?
Accurate identification of patients requiring immediate surgery versus active observation in acute appendicitis is challenging, prompting the need to evaluate clinical scoring systems and ultrasonography.
Does the combination of clinical scoring systems (Alvarado or Ohmann) and ultrasonography improve diagnostic accuracy for acute appendicitis in patients with acute right lower quadrant pain?
Population
Patients with suspected acute appendicitis and acute right lower quadrant abdominal pain
Comparison
Modified Alvarado score, Ohmann score, and ultrasonography vs histopathology

Does the combination of clinical scoring systems (Alvarado or Ohmann) and ultrasonography improve diagnostic accuracy for acute appendicitis in patients with acute right lower quadrant pain?
Absolute Event Rate: 97.22% vs 86.54%
Combining clinical scoring systems (Alvarado or Ohmann) with ultrasonography significantly improves the diagnostic accuracy for acute appendicitis compared to either modality alone.
Patnaik et al. (2019) conducted an observational in Suspected acute appendicitis (n=52). Modified Alvarado score combined with ultrasonography vs. Ultrasonography alone or modified Alvarado score alone was evaluated on Diagnostic accuracy for acute appendicitis. Combining the modified Alvarado score with ultrasonography increased the diagnostic accuracy for acute appendicitis to 97.22%, compared to 86.54% for ultrasonography alone and 78.85% for the score alone.
