Living Kidney Donor Decision Making: State of the Science and Directions for Future Research

Survey of Patient's Experience of Altruistic Nondirected Kidney Donation

The scarcity of organs for donation is an ongoing issue. Change in legislative framework allows for altruistic donations in the UK, but, whereas the number of donations from deceased donors has increased, there has been a slow decline in altruistic living donors. The aim of this study was to review perspectives of altruistic nondirected kidney donors (ANDKD) at our center and outcome of all enquiries to inform service improvement and increase the numbers of donors. All enquiries by potential ANDKD at our center from September 2005 to September 2017 were analyzed. Donor assessment was performed as per the UK Guidelines, prior to obtaining Human Tissue Authority approval. The outcome of donation and results of questionnaires sent to 50 ANDKD were analyzed. During the period, 51 of the 180 enquiries (28.3%) resulted in kidney donation. Questionnaire responses were: 66% donors were retired; most heard about altruistic donation through media (60%); 72% thought psychological or psychiatric assessment was necessary; 95% found the information provided prior to donation adequate; 82% rated their overall experience as good/excellent; and 90% would recommend kidney donation to others. Thirteen of 50 donated kidneys were fed into the kidney exchange program. The mean ± standard error of the mean of the duration from human tissue authority approval to donation were 60.4 ± 5.4 and 131.2 ± 11.2 days, respectively (P = 0.00001). A significant proportion of enquiries for altruistic donation would result in donation but the assessment process needs to be quicker. ANDKD is useful way of priming the National Living Donor Kidney Sharing Scheme.

Post-donation satisfaction in kidney transplantation: a survey of living donors in Japan

Background

No studies using a valid, standardized method to measure post-donation satisfaction levels among living kidney donors (LKDs) have been published.

Methods

Donor satisfaction levels were measured using the Japanese version of the Client Satisfaction Questionnaire-8 (CSQ-8), a validated, self-report questionnaire. To identify factors related to post-donation satisfaction levels, we compared donors’ sociodemographic and psychological characteristics and health-related quality of life (HRQoL), using the Short Form-36 Health Survey (SF-36), as well as recipients’ clinical characteristics and SF-36 scores between donors with and without low satisfaction. In addition, donors’ perceptions of the donation results and transplant procedure were assessed using measures that we developed.

Results

The mean (standard deviation [SD]) CSQ-8 score for the 195 participants was 26.9 (3.4). Twenty-nine (14.9%) respondents with total scores < 1 SD below the mean CSQ-8 score were placed into the low satisfaction group. Multiple logistic regression analysis demonstrated that lower perceptions of receiving adequate information prior to transplantation (odds ratio [OR] = 0.17; 95% confidence interval [CI] = 0.079–0.379; p < 0.001), lower optimism according to the Life Orientation Test (OR = 1.24; 95% CI = 1.045–1.470; p = 0.014), and increased serum creatinine levels in the paired recipient (OR = 0.05; 95% CI = 0.250–1.011; p = 0.054) independently increased the odds of having less satisfaction with donation.

Conclusions

Our findings suggest that careful pre-donation education and more detailed informed consent may be needed, especially in LKDs with low constitutional optimism.

Ethical Issues Surrounding High-Risk Kidney Recipients: Implications for the Living Donor

Evaulating patients for living kidney donor transplantation involving a recipient with significant medical issues can create an ethical debate about whether to proceed with surgery. Donors must be informed of the surgical risk to proceed with donating a kidney and their decision must be a voluntary one. A detailed informed consent should be obtained from high-risk living kidney donor transplant recipients as well as donors and family members after the high perioperative risk potential has been explained to them. In addition, family members need to be informed of and acknowledge that a living kidney donor transplant recipient with pretransplant extrarenal morbidity has a higher risk of a serious adverse outcome event such as graft failure or recipient death. We review 2 cases involving living kidney donor transplant recipients with significant comorbidity and discuss ethical considerations, donor risk, and the need for an extended informed consent.

Better the donor you know? A qualitative study of renal patients' views on 'altruistic' live-donor kidney transplantation

BACKGROUND

In the UK there is a short-fall between individuals requiring a renal transplant and kidneys available for transplantation. Non-directed 'altruistic' living kidney donation has emerged as a strategy for bridging this gap between supply and demand, with the number increasing each year.

OBJECTIVE

This study aimed to explore the views of potential recipients towards non-directed 'altruistic' live-donor kidney transplantation.

METHODS

Semi-structured interviews with 32 UK deceased-donor kidney transplant recipients were performed. Interviews explored willingness to consider directed and non-directed live-donor kidney transplants (LDKTs). Interviews were recorded, transcribed verbatim and transcripts were analysed using the constant comparison method described in Grounded Theory.

RESULTS

For those not willing to accept a non-directed 'altruistic' LDKT, the following themes were identified: i) Prioritising other recipients above self; ii) Fear of acquiring an unknown donor's characteristics, and iii) Concern for the donor - unnecessary risk. For those willing to accept a non-directed 'altruistic' LDKT the following themes were identified: iv) Prioritising known above unknown persons, v) Belief that they are as deserving as other potential recipients, and vi) Advantages of a LDKT.

CONCLUSIONS

Drawing on 'gift exchange theory', this study contributes to our understanding of the experience of the intended recipient of a gift. The anonymity of the donor-recipient appears to be seen as a benefit of non-directed 'altruistic' live-donor transplants, freeing recipients from the obligations of the gift. However, those who feel unworthy of the 'gifted transplant' are concerned about the donor and by the lack of opportunity for direct reciprocity. Highlighting the 'reciprocal benefits' reported by donors may allow individuals whose preference is a live-donor transplant to accept one if offered. These insights provide the transplant community with targets for intervention, through which the concerns of potential recipients might be addressed.

Living kidney donation: considerations and decision-making

BACKGROUND

When possible, renal transplantation is the treatment of choice for patients with end-stage kidney disease. Technological developments in immunology have made it possible to perform kidney transplants between donors and recipients despite antibodies against the donor organ. This allows for a wider range of relationships between recipient and donor. We investigated experiences of, and reflections on, kidney donation among genetic and non-genetic living donors before first consultation at the transplant centre.

OBJECTIVE

The aim was to investigate early experiences in the process of becoming a living kidney donor (LKD).

MATERIALS AND METHODS

The study was conducted within a phenomenological-hermeneutic theoretical framework. Data were generated through semi-structured interviews with 18 potential donors. Data were interpreted and discussed in accordance with the Ricoeur's text interpretation theory on the three levels of naïve reading, structural analysis and critical interpretation and discussion.

RESULTS

Two themes emerged: the decision-making process and dilemmas in decision-making. The study identifies that the decision about donation was made in relation to one's own life, family situation and in relation to the recipient-considerations that demonstrate that a range of dilemmas can occur during the decision-making process. The desire to help was prominent and was of significance in decision-making.

CONCLUSION

The study provides insight and knowledge for the health care professionals to meet and involve donors' narratives in reflections about and modifications to clinical nursing practice. It is essential that health care professionals have an understanding and appreciation of the experiences and concerns among LKDs, and this can help in planning and providing individual nursing care and support to donors.

Evaluation of living kidney donors: variables that affect donation

Approximately 10000 deceased donor organs are available yearly for 85 000 US patients awaiting kidney transplant. Living kidney donation is essential to close this gap and offers better survival rates. However, nationally, 80% of potential donors evaluated fail to donate. Nurse coordinators who perform predonation screening and education need additional insight into the large number of potential donors who fail to complete the donation process. Reasons for nondonation in donor candidates undergoing medical evaluation, and variables affecting nondonation at Vanderbilt University Medical Center between 2004 and 2009 are examined. Multivariable logistic regression models are used to test the effects of age and race on donation status and reasons for nondonation. Summary data are frequencies, percentages, and means (SD). The sample included 706 candidates (63% female, 80% white; mean age, 40 [SD, 12] years). Almost half (46%) received clearance to donate. Undiagnosed hypertension (14%), abnormal glucose tolerance (10%), and protein-urea (9%) were the most prevalent medical reasons for nondonation. About 13% of candidates changed their minds during evaluation. Analyses demonstrated an increased likelihood of older candidates (P < .001) and a decreased likelihood of white candidates (P = .007) being excluded from donation. Within the nondonation group, increased age was associated with undiagnosed hypertension and abnormal glucose tolerance (both race-adjusted, P = .01). Younger candidates (race-adjusted, P = .003) and African Americans (age-adjusted, P = .04) were more likely to decide against donation. The most prevalent medical reasons for nondonation could be identified through enhanced prescreening, and improved preevaluation education could decrease nondonation rates.

Decision making and psychosocial outcomes among living kidney donors: a pilot study

With an increasing number of available kidney transplant donors comes greater demand for systematic screening of prospective donors to ensure the integrity of the donor's decision and to minimize the risk of a poor postoperative outcome. The present study was intended to explore psychosocial outcomes after kidney donation, aspects of donors' decision making, and donors' experience of the transplantation process. It was hoped that this pilot study would inform the design of a large-scale longitudinal prospective investigation of psychosocial outcomes of kidney donation. In this cross-sectional, retrospective investigation, all patients who had received psychosocial screening before their kidney donation were approached. Seventeen of 43 previous kidney donors responded to a postal questionnaire. Donors' health-related quality of life was higher than population norms on all dimensions. Most participants reported involving someone else in the decision-making process. Donors indicated high levels of satisfaction with virtually all aspects of the donation process. The generalizability of the findings in the context of the limitations of the present pilot study is discussed and specific suggestions for the design of future studies are provided.

Living Kidney Donation among Hispanics: A Qualitative Examination of Barriers and Opportunities

Context

Despite their increasing need for kidneys and low nonliving donation rates, minimal research has been conducted to ascertain the perceptions of Hispanic Americans about living organ donation and the process of asking for such a donation.

Objective

To examine perceptions of Hispanics regarding barriers to and benefits of living donation as well as the process of asking someone to be a living donor.

Design

A qualitative study consisting of 10 focus groups conducted in 2 series.

Participants

Adult Spanish-language-dominant Hispanic members of the general population of Tucson, Arizona.

Results

The main barriers to living organ donation were a lack of knowledge or information and fear of the donation process. Knowing that one has helped save or improve another's life was the central benefit. Most participants reported being willing to ask a relative to be a living donor if they were ever in need. Two main responses typified these individuals: no concern about asking because of a strong desire to fight for one's health and for one's family, or asking despite difficulties and concerns about the process. A significant minority of participants indicated they would not ask for a donation, because of either a desire to avoid harming others or the expectation that a relative would initiate an offer.

Consideration of Psychosocial Factors in the Evaluation of Living Donors

Results of donor outcome studies indicate that most living donors report a positive psychosocial response to donation. However, negative psychosocial outcomes have also been reported. Evaluation guidelines have been proposed, although a standardized evaluation specific to living donors is not yet available. In an effort to determine what psychosocial factors should be considered in a comprehensive evaluation of living donors, an extensive literature review was undertaken that was focused on previously proposed guidelines for the psychosocial evaluation of living donors, research on outcomes among living donors, and other relevant psychosocial data.

Aged bodies and kinship matters: The ethical field of kidney transplant

The number of kidneys transplanted to people over age 70, both from living and cadaver donors, has increased steadily in the past two decades in the United States. Live kidney donation, on the rise for all age groups, opens up new dimensions of intergenerational relationship and medical responsibility when the transfer of organs is from younger to older people. There is little public knowledge or discussion of this phenomenon, in which the site of ethical judgment and activism about longevity and mortality is one's regard for the body of another and the substance of the body itself is ground for moral consideration about how kinship is "done." The clinic, patient, and patient's family together shape a bond between biological identity and human worth, a demand for an old age marked by somatic pliability and renewability, and a claim of responsibility that merges the "right to live" and "making live." Live kidney transplantation joins genetic, reproductive, and pharmacological forms of social participation as one more technique linking ethics to intervention and the understanding of the arc of human life to clinical opportunity and consumption. Significant in this example is the medicocultural scripting of transplant choice that becomes a high-stakes obligation in which the long-term impacts on generational relations cannot be foreseen.
