Abstract
Rationale & Objective Disparities in home dialysis therapy (HT) use may stem from the interplay between dialysis centre services and patient characteristics. We analysed how these factors directly and indirectly affect HT uptake in England.
Study design Linked UK Renal Registry (UKRR) cohort to a national survey of renal centres informed by ethnographic observation.
Setting & Participants Adults who initiated kidney replacement therapy (KRT) between 2015 and 2019 at 51 English renal centres, totalling 32,400 individuals identified through the UKRR, with centre practices captured from a 2022 national survey.
Exposures or predictors Patient- and centre-level factors
Outcomes Use of HT (home haemodialysis or peritoneal dialysis) within one year of starting KRT.
Analytical Approach Sequences of regressions, an extension of path analysis, were used to examine the direct and indirect associations between patient- and centre-level factors and the probability of HT uptake.
Results Direct associations revealed that both centre- and patient-factors significantly influenced the probability of HT uptake. Patients at centres conducting quality improvement projects, (OR [95% CI]) 1.94, [1.36-2.76]), offering assisted PD (1.89, [1.39-2.57]), fostering staff research engagement (1.35, [1.03-1.77]) or hosting HT roadshows (1.22, [1.05-1.41]) had higher odds of HT uptake. Centres with staff capacity stress had lower uptake (0.60, [0.45-0.81]). Patients on transplant lists at KRT start (2.55, [2.35-2.77]) or living further from a treatment centre (1.10, [1.08-1.12] per 10km) had higher odds of HT uptake. Patients from more deprived areas or minority ethnic groups had lower HT uptake. However, an indirect association was observed through centre practices, as certain centres serving ethnically diverse populations implemented practices that directly increased HT uptake, potentially mitigating disparities.
Limitations Healthcare professional-reported and aggregated survey data
Conclusions This study identified modifiable centre-level factors that could improve equity in HT access and uptake by mitigating ethnic and area-level disparities in diverse populations.
