Worldwide impact of oral rehydration therapy.
Oral rehydration therapy (ORT) has had a dramatic global impact. The worldwide consequences of this therapy are discussed in four categories: (1) adoption of ORT as the primary therapy for acute dehydrating diarrhea; (2) establishment of national ORT programs; (3) scientific knowledge gained from studies into intestinal absorption of oral rehydration solutions; and (4) implications of ORT for the next decade. The Diarrheal Disease Control Program has been assigned a high priority by the World Health Organization. It now includes 99% of the population of the developing world, although it is not uniformly implemented. Because knowledge of how to use ORT parallels implementation, it is hoped that expanded training of community health workers will increase implementation. In addition, specific indications for ORT need further study and refinement so that community health workers may learn to distinguish between diarrheal episodes that require such therapy and those that do not. Better scientific understanding of intestinal absorption of ORT fluids has led to the development of new formulations that enhance absorption of nutrients and repletion of electrolytes. The optimal composition of such revised solutions has yet to be established. In addition to these improvements in utilization, distribution, education, and application of ORT, other measures to reduce the morbidity and mortality from diarrhea can be expected in the areas of better infant feeding practices, improved sanitation, management of persistent diarrhea, targeted therapy for particular groups of infants at high risk, and immunization.
