Abstract

Previous studies have attempted to predict a positive stool culture in pediatric patients with acute gastroenteritis (AGE), but most of them are either from developing countries or are outdated. In all, 276 patients with AGE and 560 control patients were analyzed for differences in clinical factors including the presence of fever, highest recorded temperature, bloody diarrhea, number of bowel movements in 24 hours prior to presentation, and the presence of seizures, as well as laboratory parameters including leukocyte count and C-reactive protein (CRP). Positive stool sample rate was 13.7%. The most common bacterial pathogen was Campylobacter jejuni. Bacterial AGE was significantly associated with fever >37.9°C, bloody diarrhea, higher stool passing frequency, seizures, and CRP levels. For pediatric patients who present to the emergency department with AGE and present without bloody diarrhea, fever, frequent stool passing, or seizures, a stool culture test is of poor yield and may not be necessary.
