Quality of Life and Hemodynamic Effects of Switching From Hemodialysis to Hemodiafiltration: A Canadian Controlled Cohort Study.

ABSTRACT:

Background

Recent randomized clinical trials have demonstrated beneficial effects of hemodiafiltration (HDF) compared with hemodialysis (HD) on mortality and hemodynamic stability. Data on quality of life in HDF compared with HD is limited.

Objective

This study aimed to determine whether patients receiving HD experience improvements in quality of life, hemodynamic and laboratory parameters after switching to HDF.

Design

Observational controlled cohort study.

Setting & patients

Adult patients receiving maintenance dialysis were followed for 3 months both before and after transfer to a new unit, where they received HDF. Prior to transfer, control patients were already treated by HDF.

Methods

Quality of life at baseline and follow-up was measured using the validated minutes to recovery (MR) question. Dialysis data were collected for 3 consecutive sessions monthly; laboratory values were collected monthly. Wilcoxon signed rank test and repeated measures analysis of covariance were used to evaluate pre/post transfer changes and quantile regression to identify predictors of change in recovery time.

Results

Of 227 patients, 82 died, were transplanted, were hospitalized or did not transfer, leaving 123 subjects and 22 controls for analysis. MR did not improve with switching to HDF, although patients with MR > 60 min before transfer experienced a significant decrease in their MR, compared with controls. There was no improvement in intradialytic hypotension with HDF. There were no differences in laboratory values before vs after switch.

Limitations

Nonrandomized single-center study, including only small numbers of patients and covering a short follow-up period; hemodynamic values only evaluated over 1 week per month; residual kidney function not recorded.

Conclusions

In this Canadian experience of HDF, patients remained stable with respect to several laboratory and dialysis related parameters. Switch to HDF was associated with substantially reduced recovery time in patients with MR > 60 minutes at baseline.

Project description:ObjectiveThis study aimed to examine the effects of mindfulness meditation on trait mindfulness, perceived stress, emotion regulation, and quality of life in end-stage renal disease patients undergoing hemodialysis.MethodsAn experimental study with repeated measures design was conducted among a sample of 74 end-stage renal disease patients undergoing hemodialysis between January and May 2021 in the dialysis center at Jahra hospital, Kuwait. The patients were randomly assigned to the experimental (n = 37) and control groups (n = 37). The experimental group participated in 30-min mindfulness meditation sessions (three sessions a week for five weeks) held during their hemodialysis sessions; the participants in the control group were instructed to sit with their eyes closed and relaxed for 30 min three times a week for five weeks during hemodialysis sessions. The dependent variables of both groups were measured at baseline (T0), middle of intervention (T1), and end of intervention (T2) using the Mindful Attention Awareness Scale (MAAS), Perceived Stress Scale (PSS), Emotion Regulation Questionnaire (ERQ), and Kidney Disease Quality of Life (KDQOL-36) questionnaire. The study was registered in the ClinicalTrial.gov (Identifier: NCT05176730).ResultsThe repeated measures ANOVA (within-subject) results for the experimental group showed that mindfulness meditation had significantly decreased perceived stress by the end of the intervention. Also, mindfulness meditation improved mindfulness, emotion regulation, and kidney disease-related quality of life in the experimental group, and this improvement occurred significantly at both T1 and T2. The repeated measures ANOVA (within and between-subject) results showed that the experimental group, as compared to the control group, had lower perceived stress, higher trait mindfulness, higher emotional regulation, and higher kidney disease-related quality of life over time.ConclusionsThe positive findings of this study offer health policy-makers and hospital administrators a promising tool to use with patients undergoing hemodialysis as a way to manage stress and improve quality of life. However, this study should be replicated in multiple settings with follow-up assessments.
