The cost effectiveness of oral rehydration therapy for U.S. children with acute diarrhea.

Diarrheal disease is a common cause of morbidity among U.S. children under five years of age and exerts a heavy burden on the health care system. Oral rehydration therapy (ORT), a simple, inexpensive treatment modality that can prevent most diarrhea-related complications, is grossly underutilized in the United States. Using a decision-analysis model, this article describes the financial burden of childhood diarrhea in the United States for children under five years of age and discusses the substantial economic benefits of ORT programs. If fully implemented, such programs would save our health care system close to $1 billion annually.
