The role of the emergency medicine resident using the Alvarado score in the diagnosis of acute appendicitis compared with the general surgery resident

Abstract

Purpose: To compare the accuracy of diagnosing appendicitis between emergency medicine residents using the Alvarado score and general surgery residents using ultrasonography and their clinical provision.

Methods: A total of 358 patients (192 men and 166 women) were admitted to the emergency service with suspected appendicitis. Each patient was evaluated by an emergency medicine resident and then by a general surgeon independently. Age, sex, operational data, diagnosis, and the Alvarado scores were measured.

Results: The sensitivity and specificity of the Alvarado score were 95.4% (95% confidence interval 91-99%) and 45.7% (95% confidence interval 37.4-54%), respectively. There was a significant difference between the sexes in the predictive values of a positive test (P=0.045) and a negative test (P=0.02). There was no statistical difference between the emergency medicine residents and general surgery residents in terms of positive and negative predicitive values (P>0.05 each).

Conclusion: There was no statistical difference between the emergency medicine residents using the Alvarado score and the general surgery residents in terms of suspecting the diagnosis of appendicitis.
