Optimal Hemodialysis Vascular Access in the Elderly Patient

Abstract Background In this single-center, retrospective observational study, we assessed the long-term patency of vascular access (VA) after first VA placement to uncover independent risk factors associated with VA patency in Asian hemodialysis (HD) patients stratified by age. We also investigated factors associated with VA patency among older HD patients according to the type of VA in the overall study population. Methods The study period was from January 2011 to December 2013. A total of 651 chronic HD patients with confirmed first upper-extremity VA placement were enrolled, and their records were analyzed retrospectively. A total of 445 patients (68.4%) made up the nonelderly group (< 65 years), and 206 patients (31.6%) were in the elderly group (≥ 65 years). Study outcomes were defined as primary or secondary VA patency. Results Autologous arteriovenous fistula (AVF) was more common in the nonelderly group (P < 0.01). Kaplan–Meier curve survival analysis indicated that primary patency was longer in the nonelderly group (P < 0.01); secondary patency, however, was similar between groups (P = 0.37). The multivariate analysis of factors associated with primary VA patency revealed that increased age (hazard ratio [HR], 1.02; 95% confidence interval [CI], 1.01–1.03; P < 0.01) was associated with shorter primary patency, and AVF (HR, 0.38; 95% CI, 0.28–0.51; P < 0.01) was associated with longer primary patency. AVF (HR, 0.57; 95% CI, 0.37–0.87; P = 0.010) and diabetes mellitus (HR, 1.56; 95% CI, 1.07–2.29; P = 0.02) were independently associated with longer and shorter secondary patency periods, respectively; however, increased age was not a risk factor for decreased secondary patency. Conclusions Increased age was associated with shorter primary patency but not secondary patency, whereas AVF placement was associated with longer primary and secondary patency. Considering the similar rates of secondary patency between groups and the superior patency of AVF compared to arteriovenous graft, a fistula-first strategy should be applied to appropriate older patients.

Risk Of Death

The optimal vascular access for elderly patients remains a challenge due to the difficult balance between risks and benefits in a population with increased comorbidity and decreased survival. Long dependence to central vein catheter, patient comorbidities, life expectancy, and complication rates are important influencing the indications for arteriovenous fistula or an arteriovenous graft. Although central vein catheters are simpler way to start a hemodialysis treatment, elderly patients are also at higher risk of death from infection or other complications associated with them more than for younger patients. The discussion revolves around the following key questions: What are the limiting factors for a vascular access in the elderly patients? Central venous catheter—is it still an option for elderly patients? Is still the autologous arteriovenous fistula playing a pivotal role as hemodialysis access in the elderly patients? Are there any real surgical contraindication to perform a vascular access in elderly patients? Is the old age a limiting factor for the vascular access management?

First Choice

Current international guidelines advocate fistula creation as first choice for vascular access in haemodialysis patients, however, there have been suggestions that in certain groups of patients, in particular the elderly, a more tailored approach is needed. The prevalence of more senior individuals receiving renal replacement therapy has increased in recent years and therefore including patient age in decision making regarding choice of vascular access for dialysis has gained more relevance. However, it seems that age is being used as a surrogate for overall clinical condition and it can be proposed that frailty may be a better basis to considering when advising and counselling patients with regard to vascular access for dialysis. Frailty is a clinical condition in which the person is in a vulnerable state with reduced functional capacity and has a higher risk of adverse health outcomes when exposed to stress inducing events. Prevalence of frailty increases with age and has been associated with an increased risk of mortality, hospitalisation, disability and falls. Chronic kidney disease is associated with premature ageing and therefore patients with kidney disease are prone to be frailer irrespective of age and the risk increases further with declining kidney function. Limited data exists on the relationship between frailty and vascular access, but it appears that frailty may have an association with poorer outcomes from vascular access. However, further research is warranted. Due to complexity in decision making in dialysis access, frailty assessment could be a key element in providing patient-centred approach in planning and maintaining vascular access for dialysis.

Bed Height

Elderly patient falls are expensive and may cause serious harm. Studies have identified the sit-to-stand-and-walk (STSW) task as the task where the greatest number of elderly patient falls occur. There is a great need to identify the particular movement and environmental conditions that lead to these elderly patient falls. This study begins to address this gap by evaluating the elderly patient during self-selected hospital bed egress. Using an observed fall risk episode (FRE) as a fall proxy, statistically significant parameters were identified which include bed height, pausing prior to initiating gait, level of fall risk, and Stand phase. Low bed height was identified as the least safe bed height. Patient-specific bed height (PSBH) using the patient’s lower leg length (LLL) is recommended. In addition, suggested guidelines are presented for clinical application in setting PSBH without measuring the patient’s LLL.
