Design and application of weight gain graphs based on Bandura's self-efficacy theory for patients on maintenance haemodialysis

PurposeTo design interdialytic and daily weight gain graphs for patients on maintenance haemodialysis and to evaluate their effect on patient adherence to restricted fluid intake.MethodsForty-five patients on maintenance haemodialysis were recruited from August to October 2012. The graphs were applied for 12 weeks based on Bandura's self-efficacy theory. Adherence to restricted fluid intake, dialysis adequacy, and satisfaction were compared before and after the graphs were applied.ResultsAdherence to restricted fluid intake increased from 53.3% to 91.1%; the mean rate of urea clearance (Kt/V) decreased from 1.197 to 1.311, and the qualified rate increased from 42.5% to 70%. The rate of adherence was 86.77%; acceptance and satisfaction rates were 100%.ConclusionIt is acceptable to apply the graphs clinically for subsequent effective improvement of adherence to restricted fluid intake, promoting dialysis adequacy, and increasing patient satisfaction. Therefore, clinical application of the graphs is worthwhile.
