Evaluación de la Escala de Alvarado versus Score de respuesta inflamatoria de la apendicitis, Hospital José Carrasco Arteaga 2018

Abstract:

Background: acute appendicitis is a common disease in the environment, characterized by abdominal pain, but which often occurs with atypical clinical tables that delay its surgical treatment or discard it; so, it is necessary to have an easy and useful tool that allows the timely resolution of this pathology. Objetive: assess the usefulness of the Alvarado Scale versus the Inflammatory Response of Appendicitis (AIRs) in the diagnosis of Acute Appendicitis Method and Materials: a diagnostic test validation study was conducted to compare the AIR and Alvarado scales, considering the results of pathological anatomy as a gold test. 292 patients were included at the José Carrasco Arteaga hospital during 2018. For statistical analysis, sensitivity, specificity, positive pbkp_redictive value, negative pbkp_redictive value, ROC curve and likelihood Ratio were obtained. Results: 49.7% of the participants are in the age group of young adults, with male predominance (62.7%), married marital status 63%, mixed ethnicity 91.4%, secondary education 58.6%. The Alvarado scale had a sensitivity of 88.5%, specificity of 29.6%, positive pbkp_redictive value of 81% and negative of 42%, an LR + of 1.23 and a LR – of 0.38; that were lower than those recorded by AIR of 94.7% (sensitivity), 76.5% (specificity), positive pbkp_redictive value 93%, negative pbkp_redictive value of 80%, LR + 4.02 and one LR – 0.07. The area under the ROC curve of the AIRS was 0.897, higher than that of Alvarado of 0.611; conferring on the first scale greater diagnostic accuracy. Conclusion: the AIR Score has a higher specificity, positive pbkp_redictive value and negative pbkp_redictive value, in addition showed better diagnostic effectiveness than Alvarado's score in diagnosing acute appendicitis.
