A Pilot Randomized Controlled Trial of an Educational Program for Adults on Hemodialysis With Fatigue
A Pilot Randomized Controlled Trial of an Educational Program for Adults on Hemodialysis With Fatigue
Fatigue is a common and problematic symptom of end-stage renal disease (ESRD). The investigators have developed a new program, called the Personal Energy Planning (PEP) program, that teaches people with ESRD to manage fatigue by using energy conservation strategies during everyday life (eg. organization, prioritization, using good body postures and assistive tools). A large study is needed to test whether the program is helpful for people with ESRD. First, the investigators need to do a smaller-scale pilot study to help plan the large study. The main purposes of this pilot study are to see how many people with ESRD are willing and able to complete the PEP program, and to explore whether the program helps people feel less fatigued. The investigators plan to invite 40 people with ESRD from 4 dialysis units in Calgary, Alberta to participate. People with ESRD who report feeling unusually tired a lot of the time (using a symptom assessment tool completed every 2 months) will be asked to take part. Study participants will either do the PEP program, or another program (the control) that gives them general information about kidney disease. Participants will also be asked to complete questionnaires about fatigue before and after the study. The investigators will compare fatigue scores between the PEP program group and the control group, and record how many agree to take part in the study and complete all study activities. This pilot study will help the investigators plan next steps for research into the PEP program.
BACKGROUND: Fatigue is one of the most common, disabling, and distressing symptoms experienced by people with end-stage renal disease (ESRD; kidney failure). There are currently few evidence-based treatment options to address fatigue in the ESRD population. Energy conservation education (ECE) is a rehabilitative approach shown to improve fatigue-related outcomes in other chronic disease populations, that has yet to be studied in people with ESRD. The investigators recently developed a novel ECE program for people with ESRD, conducted acceptability and usability testing, and showed improvements in fatigue and disability in single-case studies. A large randomized controlled trial (RCT) is now required to establish the efficacy of the PEP program, but additional feasibility information is first needed to design the definitive RCT.
OBJECTIVES:
METHODS: Single-center, 1:1, parallel-arm pilot RCT. Adults on hemodialysis in Calgary at 4 dialysis units will be screened for eligibility. Prospective participants will be identified and approached by a clinical team member to assess their interest in the study. Interested patients will then be approached by a research team member to undergo informed consent and eligibility screening. Consenting participants will be randomized using a computer-generated randomization list and blocked randomization. Patients and outcome adjudicators will be blinded as to which is the treatment vs. control condition (blinding of providers is not feasible). Participants randomized to intervention will undergo the PEP energy conservation education program, consisting of two web modules and 4-7 sessions with a study clinician. Participants randomized to control will review the "Living with Kidney Disease" patient handbooks with a study clinician. Routine demographic and clinical data will be obtained at baseline, and the following measures will be administered to participants at baseline, mid-treatment, immediate post-treatment, and three months post-treatment: the Fatigue Severity Scale, Fatigue Impact Scale, Fatigue Management Questionnaire, Reintegration to Normal Living Index, and Canadian Occupational Performance Measure. A sample size of 40 patients (20 per arm) will provide an optimal estimate of treatment effect size for RCT sample size calculations, given 80% power, a small/medium effect size, and an attrition rate of ≤20%.
DATA ANALYSIS: The proportion of patients meeting each of the feasibility endpoints (eligibility, recruitment and attrition rates) will be calculated. Pre-to-post effect sizes will be calculated for all outcome measures used, and the outcome measure with the largest effect size will be chosen as the primary outcome for the RCT. Sample size calculations will then be made using the treatment effect size and variance from the pilot RCT data. Audio recordings of treatment sessions will be reviewed and rated using a Likert-scale rating system to estimate treatment fidelity. Effect sizes will also be calculated from pre-intervention to 3 months post-intervention.
IMPLICATIONS: Findings from this pilot RCT will help in the design of a robust RCT of the PEP program, which has the potential to improve fatigue management in the ESRD population.
