The purpose of this study was to determine the effectiveness of a hydration program to improve hydration and prevent conditions associated with dehydration (delirium, urinary tract infections, respiratory infections, falls, skin breakdown, and constipation). Data showed a significant increase in fluid in each body compartment, significant decrease in the number of laxatives, increase in the number of bowel movements, decline in the number of falls, and decrease in cost during the hydration period.
