Is health-related quality of life trajectory associated with dialysis modality choice in advanced chronic kidney disease?
Bibliographic record
Abstract
Background: Patients with advanced chronic kidney disease have lower health-related quality of life (HRQOL) than the general population. There is uncertainty regarding patterns of HRQOL changes before dialysis initiation. This study aimed to characterise HRQOL trajectory and assess its potential association with intended dialysis modality. Methods: This prospective single-centre cohort study followed adults with an estimated glomerular filtration rate ≤15 mL/min/1.73 m 2 for one year. Patients were allocated into one of two groups based on their intended treatment modality, ‘home dialysis’ (peritoneal dialysis or home haemodialysis (HD)) and ‘other’ (in-centre HD or conservative care). Follow-up was for up to 1 year or earlier if initiated on kidney replacement therapy or died. Kidney Disease Quality of Life – Short Form (KDQOL-SF) was completed every 6 months. Predictors of changes in KDQOL-SF components were modelled using mixed effect multivariable linear regressions. Results: One hundred and nine patients were included. At baseline, crude physical composite summary (PCS) (45 ± 10 vs. 39 ± 8) was higher in patients choosing home dialysis ( n = 41), while mental composite summary (MCS) was similar in both groups. After adjustment, patients choosing home dialysis had an increase in MCS ( B = 8.4 per year, p = 0.007) compared to those selecting in-centre HD/conservative care. This translates into an annual increase in MSC by 3 points for the ‘home dialysis’ group, compared to an annual decline by 5.4 points in the ‘other’ group. There was no difference in PCS trajectory through time. Conclusions: Patients choosing home dialysis had improved MCS over time compared to those not selecting home dialysis. More work is needed to determine how differences in processes of care and/or unmeasured patient characteristics modulate this association.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 teacher head, not a consensus.
