Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Intervention: 20-minute mindful breathing session guided by a trained research assistant in mindfulness. The session includes instructing participants to relax their body, close their eyes and focus all their attention on their breathing. If they are distracted by anything such as sounds, body sensations, thoughts, or feelings, they will be told to redirect their attention back to their breathing. The participants in the intervention group will be required to complete at least 6 sessions of 20-minute mindful breathing during dialysis treatment within 2 weeks. Attendance check-list will be used to assess the adherence to the sessions.
Intervention code [1] 317532 0
Lifestyle
Comparator / control treatment
The participants in the control group will receive "standard of care" during hemodialysis session. "Standard of care" during hemodialysis means patients will be allowed to do the usual activities they do during a dialysis session, without specific instructions from study team.
Control group
Active

Outcomes
Primary outcome [1] 323735 0
Difference in Dialysis recovery time (DRT) between baseline and 2 weeks after completion of intervention. DRT was determined by asking participants the following question: “How long does it take you to recover from a dialysis session?” This question is now recognized as a validated tool giving insight into patients’ subjective experience of dialysis. For standardization purpose, the DRT assessment was done between 2nd hour to 3rd hour of their 4 hours dialysis session. Each DRT reflected the recovery time of the previous hemodialysis (HD) session.

2 weeks
Secondary outcome [1] 382757 0
Difference in sleep quality between baseline and 2 weeks after completion of intervention. Sleep quality was assessed with the Pittsburgh Sleep Quality Index (PSQI) at T0 and T6. PSQI is a validated self-rated questionnaire which assesses sleep quality and disturbances.
Timepoint [1] 382757 0
2 weeks
Secondary outcome [2] 382758 0
Difference in health related quality of life (QOL) between baseline and 2 weeks after completion of intervention. Health related quality of life was measured with EQ-5D at T0 and T6. EQ-5D is a validated quality of life instrument that consists of the EQ-5D descriptive system that measures the five dimensions of mobility, self-care, usual activities, pain/discomfort and anxiety/depression. The EQ-VAS that measures the overall health status with a visual analogue scale marked from 0 (worst imaginable health state) to 100 (best imaginable health state).

Study design
Purpose of the study
Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Participants were randomly assigned to the intervention group or the control group based on computer generated random numbers, with a 1:1 allocation ratio. Allocation concealment was performed by concealing the random numbers in sequentially numbered sealed envelopes.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Use a randomisation table created by computer software (i.e. computerised sequence
generation)
Masking / blinding

Efficacy
Statistical methods / analysis
A planned sample size of 60 patients (30 per arm) was powered to detect the effect size difference between the two study arms of 0.8 standard deviation units (i.e. change of 160min on the DRT), with a two-tailed type I error rate of 0.05, 80% power and 15% dropout rate.

For descriptive statistics; normally distributed data will be presented by the mean and standard deviation (SD) and skewed distributions by the median and interquartile range (IQR).

The primary analysis will compare intervention groups (mindful breathing + standard of care) to control group (placebo + standard of care) on the change in Dialysis Recovery Time (DRT) between baseline and post-intervention (2 weeks) using a linear mixed model. Difference in DRT from baseline to post-intervention will be the dependent variable. Study subjects will be considered as random effects and treatment group as fixed effects. The estimated difference in DRT from baseline to 2 weeks (post-intervention) and the corresponding 95 % confidence interval (CI) will be presented.

The secondary analysis on difference in sleep quality and health related quality of life (QOL) will be analysed using the same method as for the primary outcome.

Summary
Brief summary
This is a non-blinded and randomized controlled study which studied the effect of mindful breathing on hemodialysis patients, as compared to standard of care. The effects studied were from 3 aspects, i.e. Dialysis Recovery Time, sleep quality and health-related quality of life. The mindful breathing intervention was carried out for 2 weeks, during the 6 hemodialysis sessions. The effects were compared before and after the intervention, between the mindful breathing group and control group.
