Key result
The combined use of the Alvarado score and ultrasound demonstrated a sensitivity of 96.3%, specificity of 90%, and accuracy of 89% in diagnosing acute appendicitis.
Why the study?
Acute appendicitis is the most common non-traumatic cause of acute abdominal pain requiring surgery, and the study aimed to determine the reliability of Alvarado score and ultrasound in its diagnosis.
Does the combined use of Alvarado score and ultrasound improve diagnostic accuracy for acute appendicitis in patients with abdominal pain?
Observational (n=100)

Does the combined use of Alvarado score and ultrasound improve diagnostic accuracy for acute appendicitis in patients with abdominal pain?
Combining the Alvarado score with ultrasound provides high sensitivity and specificity for diagnosing acute appendicitis, potentially reducing negative appendectomies.
May support combined Alvarado-ultrasound diagnosis in suspected appendicitis; leaves open need for prospective validation before practice change.
Background: Acute appendicitis is the commonest non traumatic cause of acute abdominal pain that needs surgical management .Alvarado score and ultrasonographies are the most cost effective, easy and available aids for diagnosis. The aim of the study was determining the reliability of Alvarado score and ultrasound in the diagnosis of acute appendicitis. Results: The study was applied with 100 cases with different types of abdominal pain at presentation with 51 males and 49 females .The sensitivity was97.3% ,specificity 90%, and accuracy 89 of combined usage of Alvarado score and U/S findings preoperatively. Patients and method: A prospective non-interventional study including patients admitted with suggestive history with signs and symptoms of acute appendicitis to the surgical emergency ward of Baghdad teaching hospital from July 1st 2017 to Feb 10th 2018, Alvarado score calculated and ultrasonography done for each patient enrolled in this study, then to be followed for intraoperative findings. Conclusions: Combined application of Alvarado score and U/S has sensitivity 94.1% ,specificity 90% and accuracy 89% . In our medical facility and emergency ward, acute appendicitis remains as one of the top acute abdominal emergencies needing surgery in patients presenting with atypical clinical finding. So diagnosis becomes difficult. So Alvarado score along with ultrasound findings are useful for increasing the reliability in emergency department for accurate diagnosis of acute appendicitis therefore there should be training for the use of U/S by emergency physician and general surgeon in the diagnosis of acute appendicitis in order to decrease the rate of negative appendectomies .

Ahmed et al. (2021) conducted an observational in Acute appendicitis (n=100). Combined Alvarado score and ultrasound vs. Intraoperative findings (gold standard) was evaluated on Diagnostic accuracy (sensitivity, specificity, accuracy) of combined Alvarado score and ultrasound. The combined use of the Alvarado score and ultrasound demonstrated a sensitivity of 96.3%, specificity of 90%, and accuracy of 89% in diagnosing acute appendicitis.
