Abstract
Introduction: Home dialysis modalities offer several clinical and economic benefits compared to facility-based dialysis treatment in patients with kidney failure. Studies have shown that sex and socioeconomic status (SES) disparities exist in access to dialysis and transplantation in patients with kidney failure, but whether similar disparities occur in access to home dialysis after kidney transplant failure is unknown. Methods: Using data from the ANZDATA registry, patients who commenced dialysis after kidney transplant failure in Australia were included (2000 2020). The associations between sex and uptake of peritoneal dialysis (PD) and home hemodialysis (HHD) at 12 months after kidney transplant failure were examined using adjusted logistic regression, with interactive effect between sex and SES evaluated. Results: Of 3,521 patients who experienced first kidney transplant failure, 1,352 (38%) were females. At 12 months following transplant failure, 483 (14%) were maintained on PD and 425 (12%) on HHD. Compared to females, males were less likely to select PD at 12 months after transplant failure, with an adjusted OR (95% CI) of 0.55 (0.44 0.68). The adjusted OR (95% CI) for the uptake of HHD at 12 months in males was 1.66 (1.29 2.12). There were significant interactions between sex and SES for the 12-month uptake of PD and HHD, such that for patients from socioeconomically disadvantaged areas, the respective adjusted ORs for the uptake of PD and HHD in male patients were 0.61 (0.45 0.84) and 2.25 (1.51 3.51) compared to female patients. Conclusion: Males who lost their kidney allografts were more likely to choose HHD over PD compared to female patients. This sex disparity was more pronounced in individuals from socioeconomically disadvantaged areas.
