ReviewA systematic data review of the cost of rehydration therapy.
Dehydration secondary to acute gastroenteritis is a commonly encountered condition among patients presenting to physicians' offices and hospital EDs. Treatment options consist of oral rehydration therapy (ORT), intravenous rehydration therapy (IVRT) and subcutaneous rehydration therapy (SCRT). Although most patients with dehydration can be effectively treated in an outpatient setting, hospitalization is frequently warranted, with estimated annual inpatient costs for dehydration therapy exceeding $US1 billion in the US in 1999 for elderly patients alone. ⋯ A total of 20 reports containing pharmacoeconomic data on rehydration therapy were evaluated. Findings suggest that ORT and SCRT may be less costly than IVRT in the treatment of mild to moderate dehydration; however, variability in cost parameters examined or data collection methods described in the literature precluded a comprehensive comparative cost-effectiveness analysis of treatment options. Future pharmacoeconomic analyses of rehydration therapy should incorporate time-motion analyses comprising a consistent set of variables to determine the most cost-effective treatment modality for patients with mild to moderate dehydration.
