Abstract
BACKGROUND
The prevalence of nonadherence to dialysis (NAD) presents a wide variation, depending on the parameters used and demographic regions studied. This study aimed to assess the prevalence and predictors of NAD of patients with chronic kidney disease undergoing hemodialysis (HD).
MATERIALS AND METHODS
This was a cross-sectional study with 255 adult patients receiving HD for >3 months. Skipping a session per month, shortening a session for at least 10 min, phosphorus >7.5 mg/dl, potassium >6.0 mmol/l and interdialytic weight gain (IDWG) >5.7% of body weight were indicative of NAD. The association of sociodemographic and clinical variables with NAD was assessed using logistic regression.
RESULTS
Mean age was 50 ± 13.1 years, 62.7% were male, 85.5% were of African descent and 62% were married. The prevalence rates of NAD were: 49% of shortening sessions, 18% of hyperkalemia, 12% of hyperphosphatemia, 9% of IDWG >5.7% of dry weight and 8% of skipping HD. Independent predictors of NAD were: age ≤50 years, not being married, living alone, living in Salvador, attending dialysis without a companion, ethnic African descent, Kt/V <1.3 and residual diuresis <100 ml/day.
CONCLUSION
NAD is frequent and distinct sociodemographic and clinical variables predict different parameters.
