The very elderly dialysis patient: indication and discontinuation of dialysis

The Full Spectrum of Clinical Ethical Issues in Kidney Failure. Findings of a Systematic Qualitative Review

BACKGROUND

When treating patients with kidney failure, unavoidable ethical issues often arise. Current clinical practice guidelines some of them, but lack comprehensive information about the full range of relevant ethical issues in kidney failure. A systematic literature review of such ethical issues supports medical professionalism in nephrology, and offers a solid evidential base for efforts that aim to improve ethical conduct in health care.

AIM

To identify the full spectrum of clinical ethical issues that can arise for patients with kidney failure in a systematic and transparent manner.

METHOD

A systematic review in Medline (publications in English or German between 2000 and 2014) and Google Books (with no restrictions) was conducted. Ethical issues were identified by qualitative text analysis and normative analysis.

RESULTS

The literature review retrieved 106 references that together mentioned 27 ethical issues in clinical care of kidney failure. This set of ethical issues was structured into a matrix consisting of seven major categories and further first and second-order categories.

CONCLUSIONS

The systematically-derived matrix helps raise awareness and understanding of the complexity of ethical issues in kidney failure. It can be used to identify ethical issues that should be addressed in specific training programs for clinicians, clinical practice guidelines, or other types of policies dealing with kidney failure.

Intensive hemodialysis in the (nursing) home: the bright side of geriatric ESRD care?

Elderly ESRD patients often lose functionality when they start dialysis, which may be due to a variety of clinical problems. We recently postulated that intensive (longer and/or more frequent) hemodialysis (HD) may be the ideal strategy to try to prevent these ESRD- and dialysis-related complications, including dialysis-induced hypotension, cardiac and cerebral events, malnutrition, infections, sleep problems, and psychological issues. The feasibility of home dialysis therapies has been demonstrated in observational studies. As self-care dialysis is often a challenge in the elderly patient, assisted intensive home HD may facilitate the long-term continuation of this modality. Intensive nursing home HD seems to be an attractive goal for the future because many elderly ESRD patients reside in an extended care facility. Combination with rehabilitation and support by social worker and psychologist remains crucial in the holistic approach toward the elderly ESRD patient. Further studies are required to test the potential protective effects of intensive HD on functionality and quality of life in elderly ESRD patients, and to elucidate the mechanisms underlying frailty and other geriatric syndromes in this highly vulnerable patient population.

Dialysis options for end-stage renal disease in older people

The numbers of older patients requiring dialysis therapy is rising, reflecting the ageing of the general population. Older dialysis patients have a tendency to present later for dialysis, have a higher number of comorbid conditions, are at higher risk of cognitive dysfunction and have increased levels of frailty. These are all barriers to home dialysis therapy so hospital haemodialysis (HD) is the predominant dialysis modality for older patients. Evidence suggests, however, that home treatment with peritoneal dialysis (PD) intrudes less into the life of older patients than hospital HD. Assisted PD is available in some countries and this enables more older patients to be treated in their own homes. Adjustments to patient education also need to be made to accommodate the barriers to learning and decision-making that often exist in older people.

Hospital admissions in elderly patients on chronic hemodialysis

BACKGROUND

The purpose of this study was to determine whether number of hospital admissions per patient per year (n/[pt-yr]) and hospital days per patient per year (d/[pt-yr]) differ between elderly and younger patients on chronic hemodialysis (HD).

PATIENTS AND METHODS

In a retrospective cohort analysis of incident HD patients in one dialysis unit over 15 years, we compared 166 HD patients older than 70 years (77.1 ± 4.7 yrs) at the onset of HD (group A) and 216 patients younger than 70 years both at onset (57.1 ± 7.6 yrs) and at the end of the HD period (group B). Eighty (48.2%) of group A and 141 (65.3%) patients of group B had diabetes mellitus.

RESULTS

No differences were noted in the overall hospitalization rate, presented as mean, {95% Confidence interval} (group A 2.40 {2.04-2.75}, group B 2.03 {1.89-2.16} n[pt-yr]) and days/[pt-year] (group A 33.6 {25.3-41.8}, group B 24.1 {18.9-29.23}). Group A had higher number of hospitalization days (P = 0.012) for surgery or trauma and higher rate (P = 0.045) and days (P = 0.041) of hospitalization for miscellaneous causes, primarily pulmonary disease, or malignancy. Among diabetic patients, group A had only a greater number of hospital days for cardiac disease (P = 0.050). Among patients without diabetes, group A had a higher number for hospital days for surgery or trauma (P = 0.027). All other univariate comparisons were not significant. Multiple linear regression identified comorbidity, quantified by the Charlson index, Caucasian race and poor compliance with the HD schedule as predictors of admission rate and days per year for vascular access issues and comorbidity, poor compliance, and advanced age at onset of HD as predictors of admission for causes other than vascular access related.

CONCLUSION

Hospitalizations, which affect quality of life, differ little between elderly and younger patients on HD. Therefore, hospitalizations do not constitute an argument for restricting access to HD to elderly patients.
