ABSTRACT
BACKGROUND: Non-adherence (NA) to hemodialysis regimens is one of the contributors to the high morbidity and mortality observed in patients with end-stage kidney disease (ESKD). We aimed to determine the prevalence and predictors of NA to hemodialysis (HD) regimens among patients on maintenance HD in Cameroon. METHODS: A cross-sectional study in two HD centers in Cameroon was conducted from January to February 2016. Consenting patients on HD for ≥3 months were included. NA to fluid restriction was defined as a mean interdialytic weight gain (IDWG) in the past month >5.7% of the dry weight, NA to dietary restriction as a pre dialysis serum phosphorus >5.5 mg/dl in a patient on phosphate binders and who is well-nourished, and NA to HD sessions as skipping at least one session in the past month. The study was approved by the institutional ethics board. RESULTS: A total of 170 (112 males) participants with a median age of 49 years (range 14-79) were included. The median dialysis vintage was 35 months (range 3-180 months). The prevalence of NA was 15.3% to fluid restriction, 26.9% to dietary restriction, and 21.2% to dialysis sessions. Age ≤49 years (p = .006, OR: 5.07, 95% CI: 1.59-16.20) and unmarried status (p = .041, OR: 2.63, 95% CI: 1.04-6.66) were independently associated with NA to fluid restrictions. No factor was associated with NA to dietary restrictions and HD sessions. CONCLUSIONS: NA to HD regimens is common amongst patients in Cameroon. Younger age and being unmarried were the predictors of NA to fluid restriction.
