Should the medicare ESRD program pay for daily dialysis? An ethical analysis

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.

Sevelamer carbonate for the treatment of hyperphosphatemia in patients with kidney failure (CKD III - V)

IMPORTANCE OF THE FIELD

Altered mineral metabolism in chronic kidney disease (CKD) is associated with increased morbidity, mortality, hospitalization, cost of care and reduced quality of life. Phosphorus control, one component of CKD metabolic derangements, is potentially related to impaired outcomes and has significant room for improvement.

AREAS COVERED IN THIS REVIEW

Historical, present and future aspects of treatment of hyperphosphatemia focusing on sevelamer hydrochloride and sevelamer carbonate.

WHAT THE READER WILL GAIN

Comprehensive insight into the background and controversies regarding phosphate binders.

TAKE HOME MESSAGE

While calcium-free phosphate binders with a sevelamer backbone may offer therapeutic advantages for CKD patients at risk, more studies comprising significant patient numbers are warranted to answer compelling clinical questions.

Temporal trends in health-related quality of life among hemodialysis patients in the United States

BACKGROUND AND OBJECTIVES

Health-related quality of life (HRQOL) is a measure of the well being of hemodialysis patients and an independent prognostic predictor. Our aim was to determine whether HRQOL among hemodialysis patients has changed over time.

DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS

We retrospectively analyzed data collected by Dialysis Clinic, Inc. from adult patients starting hemodialysis between January 1, 1997 and May 31, 2006. The primary outcome was HRQOL assessed by Short Form 36, 6 to 18 months after and closest to the 1-year anniversary of starting hemodialysis. Secular trends were analyzed by linear regression for continuous variables and logistic regression for categorical ones. Year of starting dialysis was the predictor. A five-point difference on a 0 to 100 scale was considered clinically significant.

RESULTS

Short Form 36 scores were available for 11,079 patients. Role physical, general health, vitality, social functioning, and physical component summary scores were unchanged among patients over the study period. Statistically significant (P < 0.05) but clinically insignificant changes were observed in physical functioning (-0.2 points/yr), bodily pain (+0.2 points/yr), mental health (+0.15 points/yr), and mental component summary scores (+0.13 points/yr). Only role emotional showed clinically significant improvement. Trends were unchanged after adjusting for age, gender, race, diabetes, hemoglobin, phosphorous, Kt/V, and albumin.

CONCLUSIONS

Most HRQOL domains showed either no statistically significant change or statistically but not clinically significant change over almost a decade. These results suggest that, despite important developments in hemodialysis care since 1997, little progress was made in improving HRQOL of hemodialysis patients.

Ethical issues in the care of vulnerable chronic kidney disease patients: the elderly, cognitively impaired, and those from different cultural backgrounds

Numerous ethical issues such as the appropriate initiation or withdrawal of dialysis are inherent when one cares for patients with chronic kidney disease (CKD). Conflicts concerning decisions to withhold or withdraw dialysis often involve particularly vulnerable CKD patients such as the elderly, those with cognitive impairment, or those who come from different cultural backgrounds. Issues related to renal replacement therapy in vulnerable or special CKD populations will be explored within an ethical framework based on the principles of autonomy (self-determination), beneficence (to maximize good), nonmaleficence (to not cause harm), and justice (what is due or owed).
