Purpose: To evaluate the Vesikari Scoring System (VSS) as a valuable diagnostic tool for predicting pathogens in children with acute gastroenteritis. Methods: In this retrospective study were analyzed 247 clinical and laboratory records of the Pediatric Emergency Hospital (Lima, Peru), with the diagnosis of ICD-10 A00-A009 (Intestinal Infectious diseases). According to the pathogens detected were divided into groups: non-specific, viral, and bacterial. Bacteria were detected by stool culture, viral pathogens by immune analysis. The non-specific group had negative on both tests, or they did not perform. We calculated sensitivity, specificity, negative and positive predictive values, negative and positive likelihood ratios, and receiver operating characteristic curves. Results: The area under the ROC curve of VSS was not significant for viral and bacterial etiology. The cut-off point of 9 in VSS was calculated by analyzing PPV (18,29%) and NPV (89,47%). The fecal leukocyte had a ROC of 0.8831 (IC95% 0.79-0.96 and p=0.04) for bacterial group, with a sensibility of 80,95%, specificity of 88,24% and LR- of 0,22. At a cut-off point of ≥20 fecal leukocytes was an acceptable diagnostic accuracy for bacterial gastroenteritis. The stool mucus for the bacterial group had a sensibility of 83,33%, a specificity of 82,35%, and a PPV of 95,89%. Conclusion: VSS is not an adequate diagnostic tool to differentiate viral from bacterial etiology. Nevertheless, we determine that a test of fecal leukocytes, with a cut-off point of ≥20 leukocytes per field and mucus in stools, allow us to identify the bacterial etiology of gastroenteritis.
