A pilot randomised controlled trial of an energy management programme for adults on maintenance haemodialysis: the fatigue-HD study
Bibliographic record
Abstract
BACKGROUND: Identifying interventions to reduce fatigue and improve life participation are top research priorities of people on maintenance haemodialysis. OBJECTIVE: Our primary objective was to explore the feasibility of conducting a randomised controlled trial of an energy management programme for people on maintenance haemodialysis. DESIGN: Parallel-arm, 1:1, blinded, pilot randomised controlled trial. PARTICIPANTS: Participants were recruited from 6 dialysis units in Calgary, Canada. Eligible patients were on maintenance haemodialysis, clinically stable and reported disabling fatigue on the Fatigue Severity Scale items 5, 7, 8 and 9. RANDOMISATION: Participants were randomised using a computer-generated random number sequence according to permuted blocked randomisation, stratified by dialysis unit. BLINDING: Participants were blinded to treatment allocation. INTERVENTIONS: Participants received an attention control (general disease self-management education) or the Personal Energy Planning (PEP) programme, a tailored, web-supported 7-9 weeks energy management programme. OUTCOMES: Eligibility, recruitment and attrition rates were recorded, and standardised intervention effects (Hedge's G) were calculated for fatigue and life participation questionnaires at one1-week postintervention and 12-week postintervention. RESULTS: 159 of 253 screened patients were eligible to be approached. 42 (26%) had fatigue, were interested and consented to participate, of whom 30 met eligibility criteria and were randomised (mean age 62.4 years (±14.7), 60% male). 22 enrolled participants (73%) completed all study procedures. Medium-sized intervention effects were observed on the Canadian Occupational Performance Measure (COPM)-Performance Scale, Global Life Participation Scale and Global Life Participation Satisfaction Scale at 1-week postintervention follow-up, compared with control. At 12-week follow-up, large and very large intervention effects were observed on the COPM-Performance Scale and COPM-Satisfaction Scale, respectively. CONCLUSION: It is feasible to enrol and follow patients on haemodialysis in a randomised controlled trial of an energy management intervention. As the intervention was associated with improved life participation on some measures, a larger trial is justified.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
