BACKGROUND Late nephrology referral has been associated with adverse outcomes among patients with end-stage renal disease; however, its relationship to mortality is unclear. We examined the impact of timing of nephrology care relative to initiation of dialysis on mortality after initiation of dialysis. METHODS Data from the Dialysis Morbidity and(More)
BACKGROUND Early nephrology referral of patients with chronic kidney disease (CKD) has been suggested to reduce mortality after initiation of dialysis. This retrospective cohort study of incident dialysis patients between 1995 and 1998 was performed to address the association between frequency of nephrology care during the 24 months before initiation of(More)
Cardiovascular disease is a leading cause of death among kidney transplant recipients. Anemia, a risk factor for cardiovascular complications among patients with chronic kidney disease, has not been well characterized in kidney transplant recipients. We performed a retrospective cohort study of the prevalence of and factors associated with anemia among 240(More)
BACKGROUND Current recommendations for initiating dialysis therapy are based on level of kidney function and clinical evidence of uremia. Several studies reported no benefit in patient survival from initiating dialysis therapy with a greater glomerular filtration rate (GFR). Whether this is explained by a greater comorbidity burden or detrimental effect of(More)
Comorbid conditions that develop during chronic renal insufficiency (CRI) contribute to the high morbidity and mortality among patients with end-stage renal disease (ESRD). Thus, appropriate management during CRI may lead to improved ESRD outcomes. A retrospective cohort study was performed to describe the management of patients with CRI. A total of 602(More)
BACKGROUND/AIMS Hospitalizations account for 41% of the total cost of end-stage renal disease (ESRD) care. Carnitine deficiency is common among dialysis patients, and some studies have shown improvements in anemia, and cardiac and skeletal muscle function upon administration of L-carnitine. We hypothesized that L-carnitine may be associated with decreased(More)
BACKGROUND Higher hospitalization rates among end-stage renal disease (ESRD) patients impose a substantial burden on the U.S. health care system. Early identification of patients with chronic kidney disease (CKD) and determination of factors associated with increased morbidity may lead to appropriate interventions to attenuate the complications of CKD and(More)
The strong association between anemia and cardiovascular complications among patients with end-stage renal disease suggests that anemia during chronic renal insufficiency (CRI) may also have important consequences. We performed a retrospective cohort study to identify factors associated with severe anemia (hematocrit [Hct] < 30%) and examine anemia(More)
