Fluid intake in the institutionalized elderly

Area of Science:

• Gerontology
• Nutrition Science
• Clinical Research

Background:

• Adequate fluid intake is crucial for the health of institutionalized elderly individuals.
• Established fluid intake standards vary, potentially leading to miscalculations of hydration status.

Purpose of the Study:

• To compare actual fluid intake of institutionalized elderly residents with three established hydration standards.
• To determine the adequacy of fluid intake in this population.

Main Methods:

• Direct observation and computer analysis of 3-day food and fluid intake.
• Utilized three distinct fluid intake standards (mL/kg, mL/kcal, weight-adjusted formula).
• Collected Minimum Data Set (MDS) data and medication information.

Main Results:

• Residents met or exceeded fluid intake based on 30 mL/kg and 1 mL/kcal standards.
• Fluid intake was deemed inadequate by the weight-adjusted standard (Standard 3).
• Age did not impact fluid intake adequacy; medication frequency correlated with non-meal fluid intake.

Conclusions:

• The 30 mL/kg standard may underestimate needs for underweight individuals.
• The weight-adjusted standard (Standard 3) is more appropriate for diverse body weights.
• Medication regimens can influence fluid consumption patterns in nursing home residents.
