A Comparison of Hospitalization Outcomes Between Peritoneal Dialysis and Home Hemodialysis Patients by Sex and Race
Bibliographic record
Abstract
Introduction: As interest in home dialysis as an initial dialysis modality grows, it remains unclear how the different home dialysis modalities may impact hospitalization outcomes, or how this relationship may change depending on patient sex and race. Methods: = 875) between January 2005 and December 2018 (last follow-up was in July 2020) using a nationally representative cohort of incident dialysis patients. Results: The overall hospitalization rate was 0.82 hospitalization events per patient-year. Compared with those initiated on PD, HHD patients had a lower hospitalization rate (incident rate ratio [IRR] = 0.78, 95% confidence interval [CI] 0.71-0.85), and spent fewer days in hospital (IRR = 0.68, 95% CI: 0.59-0.78). This was more pronounced in more contemporary cohorts and for males. The protective effect of HHD was stronger for Black patients. When hospitalizations were analyzed by cause, the protective effect of HHD was stronger for infection-related admissions, with Black patients seeing the largest benefit. Conclusion: The type of home modality at dialysis initiation is associated with differences in hospitalization outcomes, an association that is stronger in selected racial groups and sexes. While exploratory in nature, our work highlights the importance of further study on the differential impact of PD and HHD on hospitalization outcomes so that patients incident to dialysis may make an informed decision.

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.
