A Trial of Tap Water Treatment in the Elderly
This study is being conducted in Sonoma County, California.
Gastrointestinal illness and diarrhea are recognized as a significant cause of morbidity and mortality in the elderly. One study showed that 51% of deaths caused by diarrhea over a 9-year period occurred in individuals over the age of 74 years. Although many infectious diseases are more problematic in the elderly because of a decline in immune function and a higher incidence of pre-existing malnutrition and dehydration, it is still not known what the principal modes of transmission are and which infectious agents are responsible.
The principal objective of this study is to evaluate the ability of in-home treatment of tapwater to reduce gastrointestinal illness in non-institutionalized elderly individuals. The trial will test household-level treatment of drinking water by joint use of ultraviolet light and filtration devices. A secondary objective is an estimate of the incidence of specific bacterial, viral, and protozoan agents in stool specimens collected from elderly individuals with gastrointestinal symptoms that might be related to water consumption.
