The effectiveness of a psychoeducational intervention on health outcomes of patients undergoing haemodialysis: A randomized controlled trial

AimThe aim of this work is to examine the effectiveness of a psychoeducational intervention on self-efficacy (primary outcome), anxiety, depression, treatment adherence, and health-related quality of life (HRQoL) of patients undergoing haemodialysis. MethodsA two-group randomized controlled trial of 124 patients (65 and 59 patients in the intervention and control groups, respectively) recruited from a tertiary hospital in Singapore was conducted. Data were collected from January 2015 to June 2016. Outcomes were measured at baseline and 1, 3, and 6 months after the intervention. General linear model was used to analyse data. ResultsOur findings showed significant group effect on HRQoL (effects of kidney disease on daily life; p = 0.041), time effect on all outcomes (p < 0.05; except for treatment adherence behaviours and HRQoL [burden of kidney disease]), and group * time interaction effect on anxiety (p = 0.040) and depression (p = 0.003), with the intervention group reporting better outcomes. ConclusionsThe positive effects of our intervention on patients' self-efficacy, psychological well-being, treatment adherence attitudes, and HRQoL implied its potential use in dialysis/renal centres to improve patients' self-care and health outcomes.
