The impact of an oral rehydration clinical pathway in a paediatric emergency department.

Objective: To measure the impact of implementing an oral rehydration clinical pathway for children with mild to moderate dehydration from gastroenteritis in the paediatric emergency department (ED) on the indicators of health care utilization.
Methods: ED charts of children, six months to 17 years of age, meeting the criteria for the oral rehydration clinical pathway were reviewed. There were three 12-month periods of data collection: pre-implementation, transition and postimplementation. The clinical pathway consisted of a standard nursing assessment form and instructions on oral rehydration to be initiated and maintained by caregivers while waiting to see a physician. The primary outcome measure was ED length of visit (LOV) for children treated using the clinical pathway. This was compared with LOV for all other ED visits during the study periods to highlight the effect of the clinical pathway implementation. Secondary outcome measures included rate of intravenous rehydration, unscheduled return visits to the ED and hospital admission.
Results: During the three data collection periods, 11,816 children met the eligibility criteria. A decrease in the mean LOV of 24 min (95% CI 17 to 31) was observed, as well as a trivial decrease in the rate of intravenous rehydration therapy (14.6% to 12%) with implementation of the clinical pathway.
Conclusion: The implementation of an oral rehydration clinical pathway in the ED led to a modest reduction in the ED LOV.
