Objectives To quantify the prevalence of frailty in adult patients of all ages undergoing chronic hemodialysis, its relationship to comorbidity and disability, and its association with adverse outcomes of mortality and hospitalization. Design Prospective cohort study. Setting Single hemodialysis center in Baltimore, Maryland. Participants 146 prevalent hemodialysis patients enrolled between January 2009 and March 2010 and followed through August 2012. Measurements Frailty, comorbidity, and disability on enrollment into the study and subsequent mortality and hospitalizations. Results At enrollment, 50.0% of older (age≥65) and 35.4% of younger (age<65) hemodialysis patients were frail; 35.9% and 29.3% were intermediately frail, respectively. The 3-year mortality was 16.2% for non frail, 34.4% for intermediately frail, and 40.2% for frail participants. Intermediate frailty and frailty were associated with a 2.68-fold (95% CI: 1.02-7.07, P=0.046) and 2.60-fold (95%CI: 1.04-6.49, P=0.041) higher risk of death independent of age, sex, comorbidity, and disability. In the year after enrollment, median number of hospitalizations was 1 (IQR 0-3). The proportion with 2 or more hospitalizations was 28.2% for non frail, 25.5% for intermediately frail, and 42.6% for frail participants. While intermediate frailty was not associated with the number of hospitalizations (RR=0.76, 95%CI:0.49-1.16, P=0.21), frailty was associated with a 1.43-fold (95%CI:1.00-2.03, P=0.049) higher number of hospitalizations independent of age, sex, comorbidity, and disability. The association of frailty with mortality and hospitalizations did not differ between older and younger participants (Interaction P=0.64 and P=0.14, respectively). Conclusions Adults of all ages undergoing hemodialysis have a very high prevalence of frailty, more than 5-fold higher than community dwelling older adults. In this population, regardless of age, frailtyis a strong, independent predictor of mortality and number of hospitalizations.

Background Many patients with chronic kidney disease (CKD) have difficulties becoming actively engaged in the pursuit of pre-emptive living donor kidney transplantation. Study Design The Talking About Live Kidney Donation (TALK) study was a randomized controlled trial of the effectiveness of educational and social worker interventions designed to encourage early discussions and active pursuit of pre-emptive LKT among patients with progressive CKD. Setting & Participants We recruited participants with progressive CKD from academically affiliated nephrology practices in Baltimore, Maryland. Intervention Participants randomly received 1) “Usual Care” (routine care with their nephrologists), 2) “TALK Education” intervention (video and booklet), or the 3) “TALK Social Worker” intervention (video and booklet plus patient and family social worker visits). Outcomes We followed participants for 6 months to assess their self-reported achievement of behaviors reflecting their discussions about LKT and/or pursuit of LKT (discussions with family; discussions with physicians; initiating recipient evaluation; completing recipient evaluation; identifying a potential living donor). Measurements We assessed outcomes via questionnaire at 1, 3, and 6-month follow up. Results Participants receiving Usual Care with their nephrologists (n=44), TALK Education (n=43), and the TALK Social Worker (n=43) were similar at baseline. TALK Study interventions improved participants’ LKT discussion and pursuit behaviors, with the Social Worker leading to greater patient activation (participants’ predicted probability (95% confidence interval) of achieving LKT discussions, evaluations, or donor identification over 6 months in Usual Care, TALK Education, and TALK Social Worker groups: 30% (20%–46%), 42% (33% –54%), and 58% (41% –83%), respectively (p=0.03). Limitations Our population was well educated and mostly insured, potentially limiting generalizability of our findings. Conclusions TALK interventions improved discussion and active pursuit of LKT among patients with progressive CKD and may improve their utilization of pre-emptive LKT.

BackgroundPatients undergoing hemodialysis are at high risk of falls, with subsequent complications including fractures, loss of independence, hospitalization, and institutionalization. Factors associated with falls are poorly understood in this population. We hypothesized that insights derived from studies of the elderly might apply to adults of all ages undergoing hemodialysis; we focused on frailty, a phenotype of physiological decline strongly associated with falls in the elderly.MethodsIn this prospective, longitudinal study of 95 patients undergoing hemodialysis (1/2009-3/2010), the association of frailty with future falls was explored using adjusted Poisson regression. Frailty was classified using the criteria established by Fried et al., as a combination of five components: shrinking, weakness, exhaustion, low activity, and slowed walking speed.ResultsOver a median 6.7-month period of longitudinal follow-up, 28.3% of study participants (25.9% of those under 65, 29.3% of those 65 and older) experienced a fall. After adjusting for age, sex, race, comorbidity, disability, number of medications, marital status, and education, frailty independently predicted a 3.09-fold (95% CI: 1.38-6.90, P=0.006) higher number of falls. This relationship between frailty and falls did not differ for younger and older adults (P=0.57).ConclusionsFrailty, a validated construct in the elderly, was a strong and independent predictor of falls in adults undergoing hemodialysis, regardless of age. Our results may aid in identifying frail hemodialysis patients who could be targeted for multidimensional fall prevention strategies.

Empirical MMF therapy in the majority of patients with primary glomerulopathies was well tolerated and achieved the goals of steroid withdrawal, improvement of nephrotic syndrome, and stabilization of renal function.

Oral EAAs induce a significant improvement in the serum albumin concentration in hemodialysis but not peritoneal dialysis subjects. Further study of their long-term effects on morbidity and mortality is warranted.

BackgroundAfrican Americans have persistently poor access to living donor kidney transplants (LDKT). We conducted a small randomized trial to provide preliminary evidence of the effect of informational decision support and donor financial assistance interventions on African American hemodialysis patients’ pursuit of LDKT.MethodsStudy participants were randomly assigned to receive (1) Usual Care; (2) the Providing Resources to Enhance African American Patients’ Readiness to Make Decisions about Kidney Disease (PREPARED); or (3) PREPARED plus a living kidney donor financial assistance program. Our primary outcome was patients’ actions to pursue LDKT (discussions with family, friends, or doctor; initiation or completion of the recipient LDKT medical evaluation; or identification of a donor). We also measured participants’ attitudes, concerns, and perceptions of interventions’ usefulness.ResultsOf 329 screened, 92 patients were eligible and randomized to Usual Care (n = 31), PREPARED (n = 30), or PREPARED plus financial assistance (n = 31). Most participants reported interventions helped their decision making about renal replacement treatments (62%). However there were no statistically significant improvements in LDKT actions among groups over 6 months. Further, no participants utilized the living donor financial assistance benefit.ConclusionsFindings suggest these interventions may need to be paired with personal support or navigation services to overcome key communication, logistical, and financial barriers to LDKT.Trial registrationClinicalTrials.gov [NCT01439516] [August 31, 2011].

BackgroundFrailty, a validated measure of physiologic reserve, predicts adverse health outcomes among adults with end-stage renal disease. Frailty typically is not measured clinically; instead, a surrogate—perceived frailty—is used to inform clinical decision-making. Because correlations between perceived and measured frailty remain unknown, the aim of this study was to assess their relationship.Methods146 adults undergoing hemodialysis were recruited from a single dialysis center in Baltimore, Maryland. Patient characteristics associated with perceived (reported by nephrologists, nurse practitioners (NPs), or patients) or measured frailty (using the Fried criteria) were identified using ordered logistic regression. The relationship between perceived and measured frailty was assessed using percent agreement, kappa statistic, Pearson’s correlation coefficient, and prevalence of misclassification of frailty. Patient characteristics associated with misclassification were determined using Fisher’s exact tests, t-tests, or median tests.ResultsOlder age (adjusted OR [aOR] = 1.36, 95%CI:1.11-1.68, P = 0.003 per 5-years older) and comorbidity (aOR = 1.49, 95%CI:1.27-1.75, P < 0.001 per additional comorbidity) were associated with greater likelihood of nephrologist-perceived frailty. Being non-African American was associated with greater likelihood of NP- (aOR = 5.51, 95%CI:3.21-9.48, P = 0.003) and patient- (aOR = 4.20, 95%CI:1.61-10.9, P = 0.003) perceived frailty. Percent agreement between perceived and measured frailty was poor (nephrologist, NP, and patient: 64.1%, 67.0%, and 55.5%). Among non-frail participants, 34.4%, 30.0%, and 31.6% were perceived as frail by a nephrologist, NP, or themselves. Older adults (P < 0.001) were more likely to be misclassified as frail by a nephrologist; women (P = 0.04) and non-African Americans (P = 0.02) were more likely to be misclassified by an NP. Neither age, sex, nor race was associated with patient misclassification.ConclusionsPerceived frailty is an inadequate proxy for measured frailty among patients undergoing hemodialysis.

Laparoscopic renal biopsy is a safe, reliable, minimally invasive alternative to open renal biopsy for patients in whom a closed percutaneous approach is either a relative or absolute contraindication, which can be performed on an outpatient basis.
