Predicting noncompliance to fluid restrictions in hemodialysis patients

Following dietary restrictions is viewed as one of the most difficult parts of the regimen for patients on maintenance hemodialysis because it affects long-standing personal habits and alters lifestyle. Many patients are unable or unwilling to follow dietary recommendations, and poor compliance to fluid restrictions is a consistently reported problem that can lead to short- term and potentially fatal consequences. Several studies have attempted to assess factors that are related to dietary compliance. To date, no consistent variables have predicted either fluid compliance or noncompliance. In this study, fluid noncompliance in 141 hemodialysis patients was examined using predictor psychological, sociodemographic and medical variables. Variables significantly predictive of fluid restriction noncompliance included being male, younger, and having an external health locus of control.
