Informed dialysis modality selection among Veterans with advanced CKD: A community-level needs assessment

Abstract: Rationale & Objective: 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. Study Design: 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. Setting & Participants: 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. Ooutcomes: 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. Analytical Approach: Veterans with advanced CKD with 2 sustained estimated glomerular filtration rates <30 mL/min/1.73 m(2) 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. Results: 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. Limitations: 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. Conclusions: 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.

    Qualitative analysis of the lived experience of reproductive and pediatric health care in the military health care system

    Abstract: Introduction: Persistent inequities exist in obstetric and neonatal outcomes in military families despite universal health care coverage. Though the exact underlying cause has not been identified, social determinants of health may uniquely impact military families. The purpose of this study was to qualitatively investigate the potential impact of social determinants of health and the lived experiences of military individuals seeking maternity care in the Military Health System. Materials and methods: This was an Institutional Review Board-approved protocol. Nine providers conducted 31 semi-structured interviews with individuals who delivered within the last 5 years in the direct or purchased care market. Participants were recruited through social media blasts and clinic flyers with both maximum variation and homogenous sampling to ensure participation of diverse individuals. Data were coded and themes were identified using inductive qualitative research methods. Results: Three main themes were identified: Requirements of Military Life (with subthemes of pregnancy notification and privacy during care, role of pregnancy instructions and policies, and role of command support), Sociocultural Aspects of the Military Experience (with subthemes of pregnancy as a burden on colleagues and a career detractor, postpartum adjustment, balancing personal and professional requirements, pregnancy timing and parenting challenges, and importance of friendship and camaraderie in pregnancy), and Navigating the Healthcare Experience (including subthemes of transfer between military and civilian care and TRICARE challenges, perception of military care as inferior to civilian, and remote duty stations and international care). Conclusions: The unique stressors of military life act synergistically with the existing health care challenges, presenting opportunities for improvements in care. Such opportunities may include increased consistency of policies across services and commands. Increased access to group prenatal care and support groups, and increased assistance with navigating the health care system to improve care transitions were frequently requested changes by participants.
