ED overcrowding has been associated with poor outcomes, prolonged pain and suffering, and dissatisfaction. One of the solutions proposed in the American Academy of Pediatrics Policy Statement on ED overcrowding is that hospitals should strive to improve the efficiency of the care provided. One small step in this direction may be to improve our management of gastroenteritis and dehydration.
