Use of oral ondansetron for acute gastroenteritis in children in an emergency setting increased significantly between 2006 and 2018, but use of intravenous fluids remained consistent, based on data from a cross-sectional analysis.
Recommendations for managing acute gastroenteritis in children include oral rehydration therapy for mild to moderate cases and intravenous rehydration for severe cases, Brett Burstein, MDCM, of McGill University, Montreal, and colleagues wrote.
Oral ondansetron has been shown to reduce vomiting and the need for intravenous rehydration, as well as reduce the need for hospitalization in children with evidence of dehydration, but has no significant benefits for children who are not dehydrated, the researchers noted.
“Given the high prevalence and costs associated with acute gastroenteritis treatment for children, understanding national trends in management in a broad, generalizable sample is important,” they wrote.
In a study published in JAMA Network Open, the researchers identified data from the National Hospital Ambulatory Medical Care Survey from Jan. 1, 2006, to Dec. 31, 2018. They analyzed ED visits by individuals younger than 18 years with either a primary discharge diagnosis of acute gastroenteritis or a primary diagnosis of nausea, vomiting, diarrhea, or dehydration with a secondary diagnosis of acute gastroenteritis. The study population included 4,122 patients with a mean age of 4.8 years. Approximately 85% of the visits were to nonacademic EDs, and 80% were to nonpediatric EDs.
Overall, ED visits for acute gastroenteritis increased over time, from 1.23 million in 2006 to 1.87 million in 2018 (P = .03 for trend). ED visits for acute gastroenteritis also increased significantly as a proportion of all ED pediatric visits, from 4.7% in 2006 to 5.6% in 2018 (P = .02 for trend).
Notably, the use of ondansetron increased from 10.6% in 2006 to 59.2% in 2018; however, intravenous rehydration and hospitalizations remained consistent over the study period, the researchers wrote. Approximately half of children who received intravenous fluids (53.9%) and those hospitalized (49.1%) also received ondansetron.
“Approximately half of children administered intravenous fluids or hospitalized did not receive ondansetron, suggesting that many children without dehydration receive ondansetron with limited benefit, whereas those most likely to benefit receive intravenous fluids without an adequate trial of ondansetron and oral rehydration therapy,” the researchers wrote in their discussion of the findings.
The study findings were limited by several factors including the lack of data on detailed patient-level information such as severity of dehydration, the researchers noted. Other limitations include lack of data on return visits and lack of data on the route of medication administration, which means that the perceived lack of benefit from ondansetron may be the result of children treated with both intravenous ondansetron and fluids, they said.
“Ondansetron-supported oral rehydration therapy for appropriately selected children can achieve intravenous rehydration rates of 9%, more than threefold lower than 2018 national estimates,” and more initiatives are needed to optimize ondansetron and reduce the excessive use of intravenous fluids, the researchers concluded.
Emergency care setting may promote IV fluid use
“Acute gastroenteritis has remained a major cause of pediatric morbidity and mortality worldwide with significant costs for the health care system,” Tim Joos, MD, a Seattle-based clinician with a combination internal medicine/pediatrics practice who was not involved in the current study, said in an interview. “The authors highlight that although ondansetron use for acute gastroenteritis in the ED has increased substantially, there are still a number of children who receive intravenous fluids in the ED without a trial of ondansetron and [oral rehydration therapy] first. For the individual patient, it is not surprising that the fast-paced culture of the ED doesn’t cater to a watchful waiting approach. This highlights the need for a more protocol-based algorithm for care of these patients upon check-in.
“Often the practice in the ED is a single dose of ondansetron, followed by attempts at oral rehydration 30 minutes later,” said Dr. Joos. “It would be interesting to know the extent that outpatient clinics are practicing this model prior to sending the patient on to the ED. Despite it becoming a common practice, there is still ongoing research into the efficacy and safety of multidose oral ondansetron at home in reducing ED visits/hospitalizations.”
The study received no outside funding. The researchers had no financial conflicts to disclose. Dr. Joos had no financial conflicts to disclose. Lead author Dr. Burstein received a career award from the Quebec Health Research Fund.
