Functional dependencies among the elderly on hemodialysis.

Area of Science:

• Gerontology
• Nephrology
• Public Health

Background:

• The aging dialysis population faces challenges with daily activities, impacting patient well-being, caregiver burden, and healthcare utilization.
• Functional limitations in older hemodialysis patients require investigation to understand associated risks and clinical characteristics.

Purpose of the Study:

• To determine the prevalence of functional disability among elderly patients undergoing chronic outpatient hemodialysis.
• To identify clinical factors associated with a higher risk of disability in this patient group.

Main Methods:

• A cross-sectional study involving 162 patients aged 65 and older on chronic outpatient hemodialysis.
• Utilized the Barthel and Lawton Scales to assess dependence in basic self-care and instrumental activities.
• Employed logistic regression to analyze associations between disability and factors like age, gender, comorbidities, cognition, and physical performance.

Main Results:

• A significant proportion of older hemodialysis patients exhibited functional disability, with 85 out of 162 participants experiencing combined basic and instrumental dependence.
• Factors such as multiple prescription drug needs, impaired mobility ('up-and-go' test), and lower education levels were linked to basic self-care dependency.
• Only 8 participants showed no disability, while 69 had only instrumental dependence.

Conclusions:

• Self-care disability is a prevalent issue among elderly patients receiving hemodialysis.
• Routine identification of older dialysis patients at risk for functional impairment is necessary.
• Developing strategies to mitigate functional limitations in this vulnerable population is essential.
