Abstract
Rationale & ObjectiveMost patients with kidney failure receive hemodialysis 3 times per week in a facility. More frequent and longer duration dialysis prescriptions improve a number of key outcome measures. These prescriptions are best suited to self-care and home regimens. The Quanta SC+ hemodialysis system is a novel device with demonstrated ease of use for patients and health care practitioners through human factors testing. The primary objective of this study is to report the efficacy and safety of the SC+ system using conventional hemodialysis prescriptions.Study DesignNonrandomized observational study.Setting & ParticipantsPrevalent hemodialysis patients in 4 sites in the United Kingdom were recruited to switch from their current device to the SC+ system with no other changes to their prescription.InterventionsSC+ hemodialysis system.OutcomesEfficacy data were collected in terms of dialysis adequacy, urea reduction ratios, and net fluid removal accuracy.Results60 patients were enrolled in the study, resulting in 1,333 evaluable treatments. The threshold single-pool Kt/V of 1.2 was exceeded in 96.6% of treatments in patients receiving 3-times-weekly regimens, whereas the threshold standard Kt/V of 2.1 was exceeded in 94% of treatments and 97.6% of treatments in patients without significant residual kidney function. Ultrafiltration accuracy was determined by measuring net fluid removal and validated to be within acceptable limits. The adverse event profile during treatment was typical of hemodialysis. There were no serious adverse events.LimitationsFew patients on high-frequency treatment regimens were enrolled.ConclusionsThe SC+ system delivers safe and effective hemodialysis across a range of patients and dialysis prescriptions. It is one of the smallest systems available and has validated usability for patients to perform self-care safely with minimal training. This device may encourage patients to feel empowered to take on home hemodialysis, unlocking beneficial clinical and patient-reported outcomes associated with these modalities.

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 it
