Elderly female patients in continuing care: why are they hyperosmolar?

Area of Science:

• Gerontology
• Nephrology
• Clinical Medicine

Background:

• Hyperosmolality is a critical physiological state that can affect elderly patients.
• Maintaining proper hydration and fluid balance is essential for health, particularly in older adults.
• Continuing care settings may present unique challenges for fluid management in elderly patients.

Purpose of the Study:

• To determine the prevalence of hyperosmolar states in elderly female patients residing in continuing care facilities.
• To investigate the relationship between plasma osmolality and the degree of confusion in this population.
• To assess the impact of hydration status and fluid intake on plasma osmolality.

Main Methods:

• Cross-sectional study involving elderly female patients in continuing care.
• Measurement of plasma osmolality using standard laboratory techniques.
• Assessment of hydration status and fluid intake.
• Correlation analysis to determine relationships between variables.

Main Results:

• A high prevalence of hyperosmolality was observed, with 32 out of 39 subjects (82%) having osmolality > 295 mosm/kg.
• The mean plasma osmolality was 302 +/- 8 mosm/kg, with a range of 280-317 mosm/kg.
• No significant correlation was found between plasma osmolality and the degree of confusion (rs = 0.31, p > 0.05).
• Neither hydration status nor acute fluid intake changes significantly influenced plasma osmolality.

Conclusions:

• The majority of elderly female patients in continuing care are in a hyperosmolar state.
• Plasma osmolality in this population is not significantly related to the degree of confusion.
• Fluid management strategies may need to be re-evaluated for elderly patients in continuing care to address hyperosmolality.
