RESUMO
BACKGROUND: Many nephrology providers express difficulty in discussing care options for patients who forgo kidney replacement therapy (KRT), which hampers their ability to help patients make decisions about their current and future treatment of kidney disease. METHODS: We conducted a qualitative study using interviews with a national sample of nephrology providers (i.e., physicians and advanced practice providers) who participated in US professional societies between July and December 2022. We performed a thematic analysis of interviews to identify emergent themes reflecting providers' experiences discussing care for patients who forgo KRT. RESULTS: There were 21 providers (age 54±13years, female 81%, White 32%) who participated in interviews, of which 43% were physicians and most (57%) practiced in academic settings. Three dominant themes emerged from interviews: 1) Inconsistent terminology: while providers sought to use terms to describe care for patients who forgo KRT that affirmed patients' decision, clearly conveyed that KRT would not be pursued, and were familiar to patients and other providers, they disagreed about which terms satisfied these priorities; 2) Blurred distinctions between KRT and its alternative: providers' descriptions of their care practices suggested that differences in their approaches to caring for patients who forgo KRT and those who are planning to pursue KRT could be opaque; and, 3) Deciphering patients' decision to forgo KRT: providers did not readily accept patients' expressed preferences to forgo KRT at face value and described using a variety of methods to assess whether patients would follow through with their decision. CONCLUSIONS: Providers used different, inconsistent terms to describe care for patients who forgo KRT. They disagreed about what this care entailed and were uncertain about what patients might mean when they express not wanting to undergo KRT.
RESUMO
Introduction: Acute kidney injury (AKI) is a frequent early complication post hematopoietic stem cell transplant (HSCT), associated with high morbidity and mortality. Cord blood transplant (CBT) recipients are potentially exposed to more nephrotoxic insults, compared to patients undergoing HSCT from other donor sources. We aimed to identify risk factors for AKI in patients undergoing CBT. We also aimed to identify the impact of AKI on chronic kidney disease (CKD) and survival outcomes by one-year post-CBT. Methods: Adults and children who underwent a first CBT at our Institution were retrospectively evaluated. AKI was staged according to Kidney Disease Improving Global Outcomes (KDIGO) definitions. Cox regression models were used to estimate the association of demographic factors and post-CBT parameters with the cause-specific hazard of AKI. Results: We identified 276 patients. Median age was 32 years, 28% (77/276) were children (<18 years) and 129 (47%) were white. A myeloablative conditioning regimen was administered to 243 patients (88%) and 248 (90%) received cyclosporine for GVHD prophylaxis. One-hundred and eighty-six patients (67%) developed AKI by day 60 post-transplant, with 72 (26%) developing severe AKI (stage 2 and 3). In a multivariable analysis, each increase in bilirubin level of 1 mg/dL was associated with a 23% increase in the risk of severe AKI (adjusted HR 1.23, 95% CI 1.13 - 1.34, p<.0001). Conversely, systemic steroid administration appeared to be protective of severe AKI (unadjusted HR 0.36, 95% CI 0.18 - 0.72, p=.004) in a univariate model . Two-hundred-forty-seven patients were evaluable at the one-year time point. Among those, 100 patients (40%) developed CKD one-year post-CBT. Severe AKI was associated with a higher hazard of non-relapse mortality (adjusted HR=3.26, 95% CI 1.65-6.45, p=.001) and overall mortality (adjusted HR=2.28, 95% CI 1.22-4.27, p=.01). Discussion: AKI is a frequent complication after CBT and is associated with worse outcomes. Questions remain as to the mechanism of the protective role of steroids on kidney function in the setting of CBT.
