Introduction: The Alvarado Scale and C-reactive Protein (CRP) are tests used for the diagnosis of acute appendicitis. This pathology presents a prevalence of 7% in the hospital emergency area. The objective of the present study is to compare the sensitivity and specificity of the Alvarado scale and CRP against the results of the scale itself in order to demonstrate if there is a contribution of CRP for the diagnosis of acute appendicitis. Methods: Cross-sectional study for diagnostic tests. We worked with clinical records of patients with acute abdomen plus diagnostic suspicion of acute appendicitis treated in a surgical emergency at Hospital Suárez Angamos, between March and October of 2015. We assessed the Alvarado Scale criteria and CRP value individually and jointly taking as a gold test the result of pathological anatomy for the diagnosis of acute appendicitis. Results: A total of 449 patients were appointed to conduct this study. Moreover, patients who did not meet the inclusion criteria were excluded, leaving a total of 263 patients. For the Alvarado scale, a sensitivity of 72.7% and a specificity of 27.9% were obtained, the PCR evaluation found a sensitivity of 40% and specificity of 65.1% and in both cases the sensitivity was 81.8 and specificity Of 18.6% for a value of 1 point and sensitivity of 85.5% and specificity of 18.6% for a value of 2 points. Conclusions: when PCR is added to the Alvarado Scale, it improves the sensitivity of the latter in the case of patients with suspected diagnosis of acute appendicitis.
