Geriatric Assessment for the Nephrologist

Selecting Peritoneal Dialysis in the Older Dialysis Population

Selecting peritoneal dialysis (PD) in older individuals is a complex, multi-step process. At each step, older individuals may not have the opportunity to receive PD unless care is optimized. Older individuals are less likely to complete a PD assessment, because of unstable medical conditions, consideration of palliative care, or reluctance to approach frail patients once they are established on hemodialysis (HD). Older individuals are also more likely to have medical or social conditions that contraindicate PD or to have barriers to self-care PD that may not be overcome with support. Older individuals who are eligible for PD may be reluctant to choose it, leaving HD as the default modality. Finally, receipt of PD may be compromised by urgent HD or PD catheter-related complications at the time of insertion. Despite all these challenges, older patients can do very well on PD, so each step should be well understood and optimized in renal programs to maximize PD use in older patients.

Ageing Renal Patients: We Need More Collaboration between Geriatric Services and Nephrology Departments

There has been a significant increase in the number of frail older patients diagnosed with advanced chronic kidney disease (CKD) over the past thirty years. These elderly patients have high levels of comorbidity, and as a consequence the face of renal medicine is changing—There is an increasing need to focus on traditionally geriatric areas of expertise such as falls prevention and rehabilitation, and to shift our emphasis onto improving patient well-being rather than longevity. Over the past decade, many nephrologists have found that they are already acting as de facto “amateur geriatricians”. This denies patients both the benefits of specialist geriatric assessment, and equally importantly denies them access to the wider geriatric multidisciplinary team. This article describes the prevalence and underlying causes of the so-called “Geriatric Giants” in patients with advanced CKD, and discusses possible improvements in care that closer working with geriatricians could bring.

Groningen frailty indicator in older patients with end-stage renal disease

BACKGROUND

Currently over 55% of end-stage renal disease (ESRD) patients are aged ≥60 years and patients >75 years represent the fastest growing segment of the dialysis population. We aimed to assess whether the Groningen frailty indicator (GFI) can be used to distinguish fit older ESRD patients, likely able to tolerate and benefit from dialysis, from frail older patients who need further evaluation with a geriatrician's comprehensive assessment.

METHODS

All patients aged ≥65 years visiting the pre-dialysis unit at the Gelre hospital between 2007 and 2013 were included and underwent the GFI (n = 65). Patients with GFI ≥ 4 (frail) were referred for geriatric consultation (n = 13). Results of the GFI and nephrologists' evaluation were compared with geriatrician's assessment. Survival rates and outcomes after one year of follow up were recorded.

RESULTS

Twenty patients (32%) were identified as frail. Of the problems identified by the geriatrician in 13 patients, 55% were not reported in the nephrologists' notes. The first year after inclusion, 30% of patients with a GFI ≥ 4 died, compared to 9% of fit patients (p = 0.04). Moreover, 90% of frail patients had been hospitalized one or more times, compared to 53% in the fit group (p = 0.005).

CONCLUSION

Although the GFI can be a useful instrument to identify ESRD patients at risk, both the GFI and the nephrologists' assessment failed to identify specific geriatric impairments. Further research is needed to develop a specific frailty indicator for ESRD patients and to determine the value and effect of a comprehensive geriatric assessment in ESRD patients.

The Elderly are Different: Initiating Dialysis in Frail Geriatric Patients

Decisions and discussions about the initiation of dialysis in the elderly are often challenging because of the high prevalence of comorbidities and frailty in this population. Mortality is high, functional decline is likely, and quality of life tends to be lower in the elderly on dialysis. It is thus important to counsel these patients on the risks, benefits, and burdens of dialysis to assist them in making an informed choice that is in line with their goals, preferences, and expectations. For some patients, dialysis may be a desirable choice. For others, the alternative of palliative care may provide a more favorable balance of benefits versus burdens. Elderly patients who choose to proceed with dialysis often benefit from an interdisciplinary team that helps to manage and monitor their health status, while maximizing the benefits of treatment and decreasing its potential harms. These goals can be promoted by effective communication and through individualized decisions about vascular access, medication choices, and dietary limitations. Finally, close monitoring of functional status will help to determine whether dialysis remains in a patient's best interest and when alternatives should be offered.
