Clin-Star corner: what is new at the interface of geriatrics and nephrology?
In this article, the authors highlight key findings of three recent original investigations in nephrology and describe each study, the relevance to the care of older adults, and current areas of uncertainty that warrant further investigation. The three articles relate to removal of the race adjustment in the estimation of kidney function, the use of novel therapeutics to halt chronic kidney disease progression and improve cardiovascular outcomes, and medication management for short-term pain control in chronic kidney disease.

Validation of prognostic indices for short term mortality in an incident dialysis population of older adults >75.
Prognosis provides critical knowledge for shared decision making between patients and clinicians. While several prognostic indices for mortality in dialysis patients have been developed, their performance among elderly patients initiating dialysis is unknown, despite great need for reliable prognostication in that context. The purpose of this study was to assess the performance of 6 previously validated prognostic indices to predict 3 and/or 6 months mortality in a cohort of elderly incident dialysis patients.

Arteriovenous fistula placement, maturation, and patency loss in older patients initiating hemodialysis.
The current clinical guidelines for vascular access do not have specific recommendations for older hemodialysis patients. This retrospective cohort study aimed to determine the association of age with arteriovenous fistula (AVF) placement, maturation, and primary and secondary patency loss among older hemodialysis recipients. The authors conclude that the likelihood of AVF maturation is an important consideration for vascular access planning.

Long-term outcomes among Medicare patients readmitted in the first year of hemodialysis: a retrospective cohort study.
This retrospective cohort study examined long-term outcomes among Medicare patients with end-stage renal disease (ESRD) during the first year of hemodialysis. The goal was to determine hospital readmission patterns in the first year of dialysis and outcomes in the second year. Data from the United States Renal Data System (USRDS) was used and readmission patterns were summarized as either no readmission within 30 days, at least one admission, but not within 30 days, and admission with at least one readmission within 30 days. About half of all patients did not get readmitted (51%), but 18.5% were readmitted within 30 days, and 30.5% were admitted but not within 30 days. Those who were readmitted within 30 days had the highest long-term risk of mortality, hospitalization and lower likelihood of kidney transplantation compared to patients who were not admitted or readmitted.

Gender disparities in vascular access surgical outcomes in elderly hemodialysis patients.
In this study, the investigators assessed clinically relevant arteriovenous fistulas (AVF) and arteriovenous grafts (AVG) surgical outcomes in elderly male and female patients initiating hemodialysis with a central venous catheter (CVC). The investigators concluded that while AVFs should be considered the preferred vascular access in most circumstances, clinical AVF surgical outcomes were uniformly worse in females. They suggest that clinicians should also consider AVGs as a viable alternative in elderly female patients initiating hemodialysis with a CVC to avoid extended CVC dependence.

Tradeoffs in vascular access selection in elderly patients initiating hemodialysis with a catheter.
In this study the investigators evaluated clinically relevant vascular access outcomes in elderly patients receiving an arteriovenous fistulas (AVF) or arteriovenous grafts AVG after hemodialysis therapy initiation. The investigators found that in elderly hemodialysis patients initiating hemodialysis therapy with a catheter, the optimal vascular access selection depended on tradeoffs between shorter catheter dependence and less frequent interventions to make the vascular access (AVG) functional versus longer access patency and fewer interventions after successful use of the vascular access (AVF).

Vascular access type and clinical outcomes among elderly patients on hemodialysis.
This observational study design was used to compare clinical outcomes in elderly patients who initiated hemodialysis with a central venous catheter and subsequently had an arteriovenous fistula or graft placed. The study concluded that despite extended central venous catheter dependence, elderly patients initiating hemodialysis with a central venous catheter who underwent arteriovenous fistula placement within 6 months had fewer hospitalizations due to infections and a lower likelihood of death than those receiving an arteriovenous graft.

Association of reduced eGFR and albuminuria with serious fall injuries among older adults.
The researchers studied adverse outcomes in patients on dialysis as a result of falls. They found that among participants with CKD, cumulative 1-year mortality rates among patients with a serious fall and age-matched controls were 21.0% and 5.5%, respectively, and noted that elevated ACR but not lower eGFR was associated with serious fall injuries. They concluded that evaluation for fall risk factors and fall prevention strategies should be considered for older adults with elevated ACR.

Antihyperglycemic medication use among Medicare beneficiaries with heart failure, diabetes mellitus, and chronic kidney disease.
The authors sought to investigate the overall use and safety of antihyperglycemic medications (AHMs) among patients with diabetes mellitus, heart failure, and chronic kidney disease. They found that treatment of diabetes mellitus in patients with HF and chronic kidney disease is complex, and these patients are commonly treated with renal contraindicated AHMs, including over 6% receiving a thiazolidinedione, despite known concerns regarding HF. They recommended more research regarding safety and efficacy of various AHMs among HF patients.

Reduced cardiovascular mortality associated with early vascular access placement in elderly patients with chronic kidney disease.
This study assessed whether there has been a decrease in cardiovascular comorbidity in elderly chronic kidney disease (CKD) patients undergoing predialysis access surgery, and whether this impacted clinical outcomes after access creation and cardiovascular events after hemodialysis initiation. It concluded that a progressive decrease in cardiovascular comorbidities in elderly CKD patients undergoing predialysis vascular access surgery was associated with a decrease in death before hemodialysis and cardiovascular events after starting hemodialysis.

Systolic BP and mortality in older adults with CKD.
This study sought to determine whether a nonlinear relationship between BP and mortality - as described for the broader chronic kidney disease (CKD) population and for older adults in the general population - is present for older adults with CKD. It found that in a cohort of older adults, a relationship between higher SBP and mortality was present only for younger members of this cohort and not for those older than 70.

Risk factors for acute kidney injury in older adults with critical illness: a retrospective cohort study.
The authors sought to delineate the determinants of risk for acute kidney injury (AKI) in older compared with younger adults. They found that among the risk factors for AKI in the oldest age category were drugs (vancomycin, aminoglycosides, and nonsteroidal anti-inflammatories), history of hypertension, and sepsis. Fewer variables remained predictive of AKI as age increased and the model for older patients was less predictive.

Form CMS-2728 data versus erythropoietin claims data: implications for quality of care studies.
The purpose of this study was to compare predialysis erythropoietin-simulating agents (ESA) care reported on Form CMS-2728 with Medicare claims for ESA treatment submitted for patients 67 years and older at initiation of dialysis with Medicare as the primary payer. It found that the agreement between Form CMS-2728 and claims data is poor and discordant results are observed when comparing the use of these data sources to predict health outcomes.
