AIMS: The aim of this study was to prospectively compare two groups with suspected acute appendicitis, analyzing the number of imaging tests requested, waiting time in the emergency department, until definition of conduct, as well as the sensitivity and specificity of this diagnostic method.  METHODS: This is a prospective randomized study comparing 55 patients submitted to clinical-radiological diagnosis according to the routine of the service (control group), with another 55 patients submitted to the Appendicitis Inflammatory Response score flowchart (intervention group).  RESULTS:  Waiting time for defining the intervention group\u2019s conduct was 1.5 h shorter than the control group (p=0.02). Computed tomography was performed in 42 patients in the control group, compared with 25 in the intervention group (p=0.001). The impact of the flowchart based on the Appendicitis Inflammatory Response score of the cases compared to the control group was the reduction of appendectomies with a normal-appearing appendix from 5 to 1 and an increase in the exclusion of appendicitis diagnoses. The use of the Appendicitis Inflammatory Response score resulted in a diagnostic specificity of 92%, compared to 29% in the control group.  CONCLUSIONS:  The use of the Appendicitis Inflammatory Response score reduced the waiting time for the diagnosis of acute appendicitis, decreased the number of imaging tests, and increased diagnostic specificity of the disease.<\/jats:p>","DOI":"10.1590\/0102-672020220002e1686","type":"journal-article","created":{"date-parts":[[2022,9,16]],"date-time":"2022-09-16T18:27:37Z","timestamp":1663352857000},"source":"Crossref","is-referenced-by-count":8,"title":["THE APPENDICITIS INFLAMMATORY RESPONSE SCORE FOR ACUTE APPENDICITIS: IS IT IMPORTANT FOR EARLY DIAGNOSIS?"],"prefix":"10.1590","volume":"35","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-8788-5133","authenticated-orcid":false,"given":"Vitor Steil","family":"DEBONI","sequence":"first","affiliation":[{"name":"S\u00e3o Jos\u00e9 Municipal Hospital,  Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2805-5639","authenticated-orcid":false,"given":"Matheus Ign\u00e1cio","family":"ROSA","sequence":"additional","affiliation":[{"name":"S\u00e3o Jos\u00e9 Municipal Hospital,  Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1752-062X","authenticated-orcid":false,"given":"Andr\u00e9 Carminati","family":"LIMA","sequence":"additional","affiliation":[{"name":"S\u00e3o Jos\u00e9 Municipal Hospital,  Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4643-929X","authenticated-orcid":false,"given":"Agnaldo Jos\u00e9","family":"GRACIANO","sequence":"additional","affiliation":[{"name":"S\u00e3o Jos\u00e9 Municipal Hospital,  Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9887-1805","authenticated-orcid":false,"given":"Christian Evangelista","family":"GARCIA","sequence":"additional","affiliation":[{"name":"S\u00e3o Jos\u00e9 Municipal Hospital,  Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"530","published-online":{"date-parts":[[2022]]},"reference":[{"issue":"11","key":"ref1","doi-asserted-by":"crossref","first-page":"1451","DOI":"10.1002\/bjs.10637","article-title":"Randomized clinical trial of Appendicitis Inflammatory Response score-based management of patients with suspected appendicitis","volume":"104","author":"Andersson M","year":"2017","journal-title":"Br J Surg"},{"issue":"22","key":"ref2","doi-asserted-by":"crossref","first-page":"2277","DOI":"10.1056\/NEJMra072149","article-title":"Computed tomography-an increasing source of radiation exposure","volume":"357","author":"Brenner DJ","year":"2007","journal-title":"N Engl J Med"},{"issue":"1","key":"ref3","doi-asserted-by":"crossref","DOI":"10.1590\/0102-672020180001e1339","article-title":"Diagnostic value of c-reactive protein and the influence of visceral fat in patients with obesity and acute appendicitis","volume":"31","author":"Castro AA","year":"2018","journal-title":"ABCD Arq Bras Cir Dig"},{"issue":"1","key":"ref4","doi-asserted-by":"crossref","first-page":"27","DOI":"10.1186\/s13017-020-00306-3","article-title":"Diagnosis and treatment of acute appendicitis: 2020 update of the WSES Jerusalem guidelines","volume":"15","author":"Di Saverio S","year":"2020","journal-title":"World J Emerg Surg"},{"issue":"10","key":"ref5","doi-asserted-by":"crossref","first-page":"1060","DOI":"10.1097\/PEC.0b013e3182a5c9b6","article-title":"Evaluation of a novel pediatric appendicitis pathway using high- and low-risk scoring systems","volume":"29","author":"Fleischman RJ","year":"2013","journal-title":"Pediatr Emerg Care"},{"issue":"6","key":"ref6","doi-asserted-by":"crossref","first-page":"488","DOI":"10.1001\/jama.1997.03540300056034","article-title":"Clinical prediction rules.
