Improving Incident ESRD Care Via a Transitional Care Unit.

Dialysis care in the United States continues to move toward an emphasis on continuous quality improvement and performance benchmarking. Government- and industry-sponsored programs have evolved to assess and incentivize outcomes for many components of end-stage renal disease care. One aspect that remains largely unaddressed at a systemic level is the high-risk transition period from chronic kidney disease and acute kidney injury to permanent dialysis dependence. Incident dialysis patients experience disproportionately high mortality and hospitalization rates coupled with high costs. This article reviews the clinical case for a special emphasis on this transition period, reviews published literature regarding prior transitional care programs, and proposes a novel iteration of the first 30 days of dialysis care: the transitional care unit (TCU). The goal of a TCU is to improve awareness of all aspects of renal replacement therapy, including modalities, access, transplantation options, and nutritional and psychosocial aspects of the disease. This enables patients to make truly informed decisions regarding their care. The TCU model is open to all patients, including incident patients with end-stage renal disease, those for whom peritoneal dialysis is failing, or those with failing transplants. This model may be especially beneficial to those who are deemed inadequately prepared or "crash start" patients.

Glomerular Disease in Temporal Association with SARS-CoV-2 Vaccination: A Series of 29 Cases.

Background: Immune responses to vaccination are a known trigger for a new onset of glomerular disease or disease flare in susceptible individuals. Mass immunization against SARS-CoV-2 in the COVID-19 pandemic provides a unique opportunity to study vaccination-associated autoimmune kidney diseases. In the recent literature, there are several patient reports demonstrating a temporal association of SARS-CoV-2 immunization and kidney diseases. Methods: Here, we present a series of 29 cases of biopsy-proven glomerular disease in patients recently vaccinated against SARS-CoV-2 and identified patients who developed a new onset of IgA nephropathy, minimal change disease, membranous nephropathy, ANCA-associated GN, collapsing glomerulopathy, or diffuse lupus nephritis diagnosed on kidney biopsies postimmunization, as well as recurrent ANCA-associated GN. This included 28 cases of de novo GN within native kidney biopsies and one disease flare in an allograft. Results: The patients with collapsing glomerulopathy were of Black descent and had two APOL1 genomic risk alleles. A brief literature review of patient reports and small series is also provided to include all reported cases to date (n=52). The incidence of induction of glomerular disease in response to SARS-CoV-2 immunization is unknown; however, there was no overall increase in incidence of glomerular disease when compared with the 2 years prior to the COVID-19 pandemic diagnosed on kidney biopsies in our practice. Conclusions: Glomerular disease to vaccination is rare, although it should be monitored as a potential adverse event.

Economic analysis of angiography and preemptive angioplasty to prevent hemodialysis-access thrombosis.

OBJECTIVES: We sought to determine the economic value of early angiography and prophylactic angioplasty to prevent hemodialysis-access thrombosis. BACKGROUND: End stage renal disease consumes more than 6% of the Medicare budget. There is a need to understand the financial impact of each component of care. METHODS: We conducted an observational economic analysis of a closed cohort of 818 hemodialysis patients, of whom 560 were referred for 1437 consecutive radiographic procedures during an 8-year period. Patient-level, bottom-up microcosting methods provided supply and personnel costs before and after expansion of an angiographic referral program. RESULTS: The rate of referral for malfunctioning but nonthrombosed hemodialysis accesses increased from 18.8 +/- 8.8 to 48.3 +/- 11.9 angiographic procedures per 100 patient-years (P < 0.001), which was associated with a decline in access thrombosis from 27.6 to 22.0 events per 100 patient-years (P = 0.029) and a net cost of $34,586 per 100 patient-years. The incremental cost-effectiveness ratio for invasive surveillance was $6,177 per thrombosis event avoided. The angiographic program expanded at the same time that the proportion of autogenous fistulas increased from 28.3% +/- 11.3% to 59.7% +/- 10.7% of total referrals (P = 0.0001). On multivariable logistic regression analysis, the expanded angiography program (P = 0.001) and the proportion of autogenous fistulas (P = 0.0001) were both independently associated with the reduction in access thrombosis. CONCLUSIONS: Given the incremental costs and the relatively modest benefits in preventing access thrombosis, preemptive angiographic management may represent a less efficient use of healthcare resources than increasing the number of patients with autogenous fistulas.
