Compliance in hemodialysis patients: a multivariate regression analysis

Area of Science:

• Nephrology
• Internal Medicine
• Public Health

Background:

• End-stage renal failure (ESRF) management necessitates strict adherence to dialysis, dietary, fluid, and medication regimens.
• Patient compliance significantly impacts treatment outcomes and morbidity in chronic hemodialysis patients.

Purpose of the Study:

• To investigate the multifactorial influences on patient compliance with treatment regimens in chronic hemodialysis.
• To identify key demographic and habitual variables affecting adherence to diet, fluid, and medication intake.

Main Methods:

• Serum potassium (K) and phosphate (PO4) levels, along with interdialytic weight gain, were measured in 50 chronic hemodialysis patients.
• Statistical analysis was employed to determine correlations between compliance indices and patient demographics (age, sex, ethnicity, education, etc.) and dialysis-related factors.

Main Results:

• Dietary compliance was independent of fluid or medication adherence, but fluid and medication compliance were correlated (p=0.01).
• Serum K levels were influenced by age, time on dialysis, place of birth, and accompaniment to dialysis.
• Serum PO4 levels were significantly affected by sex, ethnic origin, and education; fluid intake was influenced by sex, place of birth, marital status, number of children, and years of education.

Conclusions:

• Patient compliance with hemodialysis regimens is complex and influenced by a multitude of factors.
• Targeted educational programs for low-compliance patient populations are crucial for improving adherence and reducing morbidity/mortality.
