Abstract
The Advancing Americans Kidney Health Executive order has directed substantial increases in home dialysis use for incident kidney replacement therapy (KRT). Clinical guidelines recommend patients' self-selection of KRT modality through a shared decision-making process, which, at the minimum, requires predialysis nephrology care and KRT-directed comprehensive prekidney failure patient education (CoPE). The current state of these essential services among Americans with advanced (stages 4 and 5) chronic kidney disease (CKD) and their informed preferences for home dialysis are unknown. We conducted a community-based, cross-sectional, observational cohort study across a large regional Veteran Healthcare System from October 1, 2020, to September 30, 2021. Of the 928 Veterans with advanced CKD, 287 (30.9%) were invited for needs assessment evaluations. Of the 218 (76% of invited cohort) responding, 178 (81.6%) were receiving nephrology care, with approximately half of those (43.6%) receiving such care from non-Veterans Affairs providers. The study was targeted to assess the prevalent state of ongoing nephrology care and KRT-directed pre-kidney failure education among Veterans with advanced CKD. The secondary outcome included evaluation of dialysis decision-making state among Veterans with advanced CKD. Veterans with advanced CKD with 2 sustained estimated glomerular filtration rates<30mL/min/1.73m2 were identified through an electronic database query, and a randomly selected cohort was invited for their current state of and outstanding needs for predialysis nephrology care and CoPE, essential for informed KRT selection. Basic awareness of kidney disease was high (92.2%) among Veterans with advanced CKD, although only 38.5% were aware of the severity of their CKD. KRT-directed education during clinical care was reported by 46.8% of Veterans, of which 21.1% reported having received targeted CoPE classes. Three-quarters (74.3%) of Veterans expressed interest in receiving CoPE services. Overall, awareness of CKD and its severity and receipt of KRT-directed education were significantly higher among Veterans with nephrology care than among those without. Of the 61 Veterans providing their KRT preferences, overall decision making was poor, with three-quarters (73.8%) of the cohort unable to choose any KRT modality, irrespective of ongoing nephrology care. Only 8 (13%) felt confident choosing home KRT modalities. The study results are primarily applicable to the Veterans with advanced CKD. Furthermore, a limited numbers of respondents provided data on their KRT decision-making state, prohibiting broad generalizations. In a first-of-its-kind community-based needs assessment evaluation among Veterans with advanced CKD, we found that awareness of kidney disease is positively associated with nephrology care; however, the informed KRT selection capabilities are universally poor, irrespective of nephrology care. Our results demonstrate a critical gap between the recommended and prevalent nephrology practices such as KRT-directed education and targeted CoPE classes required for informed patient-centered home dialysis selection in advanced CKD.
