Clinical Practice Guideline for the Treatment of Pediatric Acute Gastroenteritis in the Outpatient Setting.

Acute gastroenteritis (AGE) is a common illness in childhood that usually can be treated in the outpatient setting. Inaccurate assessment or delayed treatment of AGE can lead to an increased risk for invasive interventions. A literature search was conducted using PubMed, CINAHL Plus, the Cochrane Library, and Embase. Results of the query were refined to narrow the focus of relevant studies for the provider caring for dehydrated children in the outpatient setting. Use of clinical dehydration scales to assess the level of dehydration and early initiation of oral rehydration therapy promote optimal patient outcomes. Oral rehydration therapy remains the best means of rehydrating, and ondansetron is a safe and effective adjunct to help children with persistent vomiting. The purpose of this practice guideline is to identify best practices for AGE in children older than 6 months with symptoms for less than 7 days who are being cared for in the outpatient setting.
