Effectiveness of a brief hope intervention for chronic kidney disease patients on the decisional conflict and quality of life : a pilot randomized controlled trial

Abstract

Background: Stage 5 chronic kidney disease (CKD) patients often experience decisional conflict when faced with the selection between the initiation of dialysis and conservative care. The study examined the effects of a brief hope intervention (BHI) on the levels of hope, decisional conflict and the quality of life for stage 5 CKD patients. Methods: This is a single-blinded, randomized controlled trial (ClinicalTrials.gov identifier: NCT03378700). Eligible patients were recruited from the outpatient department renal clinic of a regional hospital. They were randomly assigned to either the intervention or the control group (intervention: n = 35; control: n = 37). All participants underwent a customized pre-dialysis education class, while the intervention group received also BHI. Data were collected prior to the intervention, immediately afterwards, and one month following the intervention. The Generalized Estimating Equation was used to measure the effects in the level of hope, decisional conflict scores (DCS) and Kidney Disease Quality of life (KDQOL-36) scores. Estimated marginal means and standard errors with 95% confidence intervals of these scores were also reported to examine the within group and between group changes. Results: An increase of the hope score was found from time 1 (29.7, 1.64) to time 3 (34.4, 1.27) in the intervention group. The intervention had a significant effect on the KDQOL-36 sub-scores Mental Component Summary (MCS) (Wald χ2 = 6.763, P = 0.009) and effects of kidney disease (Wald χ2 = 3.617, P = 0.004). There was a reduction in decisional conflict in both arms on the DCS total score (Wald χ2 = 7.885, P = 0.005), but the reduction was significantly greater in the control group (effect size 0.64). Conclusions: The BHI appeared to increase the level of hope within the intervention arm. Nonetheless, differences across the intervention and control arms were not significant. The KDQOL-36 sub-scores on MCS and Effects of kidney disease were found to have increased and be higher in the intervention group. The DCS total score also showed that hope was associated with reducing decisional conflict.
