Factors Influencing Living Kidney Donation in Singapore

The general public's attitude towards accepting payment for kidney donation

Introduction

Kidney transplantation has become the most cost-effective treatment for patients with end-stage kidney disease (ESKD) and offers them the highest quality of life. Yet, kidney donation is often inaccessible due to cultural and traditional beliefs about organ donation. The goal of our study is to assess the value of kidney donation using the Willingness to Accept (WTA) technique. We also aim to understand the factors influencing an individual's willingness to donate an organ.

Methods

A self-administered survey was completed by 985 participants from the general public. The quantitative method and survey design that were chosen used descriptive, correlational, nonparametric, and multivariate statistical tests.

Results

Most of the respondents, 895 (90.9%) are not willing to donate a kidney while alive. Four hundred and five (41.1%) of the respondents are not willing to donate a kidney after their death, while the rest are willing to donate their kidney after their death without financial compensation. The same attitude applies to the donation of a kidney from their relatives. Significant predictors from the results of the logistic regression model in predicting the lowest (minimal) amount that will encourage donation of one kidney after death were: Marital status; Nationality; Adi card holder; Knowing people who need a kidney donation; confidence in the medical staff; and consideration of the family's opinions regarding organ donation.

Discussion

Using cost benefit analysis (CBA), with the aim of evaluating the willingness of individuals to accept payment for innovative medical procedures, such as kidney donation, allows an assessment of the perceived value of the medical procedure and enables policymakers to decide whether to allocate funds or offer subsidies for kidney donation, given the limited healthcare resources available. During our research, we found that most participants did not support the commercialization of organs. Our recommendation for policymakers and health professionals is to continue providing adequate funding for kidney donations and to implement educational programs aimed at improving attitudes towards organ donation.

Polish attitudes towards unspecified kidney donation: a cross-sectional study

BACKGROUND

Chronic kidney disease effects about 4.2 million people in Poland, yet Polish organ donation research is rare. In addition, compared to other countries in the world, Poland has a relatively low living donation rate. Still, little is known about how Poles would react to the possibility of living kidney donation to strangers. A study was conducted to examine public opinion about living kidney donation, as well as their knowledge about it, willingness to donate to a stranger, and support for a possible expansion of existing Polish organ donation legislation to include living donation to strangers.

METHODS

A self-report questionnaire, which included a socio-demographic datasheet (9 questions), 16 questions about attitudes towards living donation, and 1 question about knowledge concerning transplantation law was sent to the respondents from December 2020 - February 2021. Logistic regression was used to assess factors affecting the support of the legalization of unspecified kidney donation amongst the participants.

RESULTS

More than sixty percent (62.1) of respondents supported legalization of unspecified living kidney donation. Such legalization would be accepted by people who accept a choice of a family member to donate a kidney to a stranger (OR = 3.50; Cl 95%: 1.49 to 4.85), who think bone-marrow transplant is safe (OR = 2.65; Cl 95%: 1.80 to 3.91), recognize the benefit of carrying out tests before donating a kidney (OR = 2.56; Cl 95%: 1.79 to 3.69), would agree to receive a kidney from another person (OR = 2.24; Cl 95%: 2.53 to 3.13), or would agree to donate organs after death (OR = 2.06; Cl 95%: 1.45 to 2.95). However, support for unspecified living kidney donation would not be given by respondents fearing the risk of organ trafficking (OR = 0.54; Cl 95%: 0.38 to 0.79).

CONCLUSIONS

In Poland there is strong support for legalization of unspecified living kidney donation. It is vital that future legislation define organ trafficking as a crime with serious punishment so that legal unspecified living kidney donation is not hindered.

TRIAL REGISTRATION

The study was registered with ClinicalTrials.gov (ID: NCT04789122 ) on 08/03/2021.

Factors Associated with the Willingness to Become a Living Kidney Donor: A National Cross-Sectional Study

Introduction: Living donor kidney transplantation is the preferred method of treating kidney failure. The donor agrees to undergo an elective procedure for the benefit of the recipient. Aim: To assess the attitude toward living kidney donation and to investigate the factors that contribute to kidney donation willingness. Methods: A cross-sectional study was carried out between December 2020 and February 2021. The study covered a representative group of 953 Poles aged 18−77, living in all Polish voivodships. The relationship between sociodemographic factors, personal values (Personal Values List), the total score of life satisfaction (Satisfaction with Life Scale) and the willingness to donate a kidney to another human was assessed using a logistic regression model. Results: The most frequently chosen personal values were: good health; physical and mental fitness; love and friendship; knowledge and wisdom. The most frequently chosen symbols of happiness were: good health, successful family life, being needed by others. The median satisfaction with life for the entire group was 20 [16; 24]. Voluntary donation of a kidney to another human being i.e., family, friends, strangers were more often declared by women (OR = 1.21; Cl95%: 1.03−1.42), for whom the most important symbol of happiness was a life full of adventures, travels (OR = 1.39; Cl95%: 1.06−1.82) and the most important personal value was goodness and tenderness (OR = 1.21; Cl95%: 1.05−1.40). Total scores of The Satisfaction with Life Scale correlated positively with the willingness to voluntarily donate a kidney (OR = 1.03; Cl95%: 1.003−1.06), while age correlated negatively (OR = 0.99; Cl95%: 0.98−0.99). Conclusions: Respondents who declare their willingness to be a living kidney donor are mainly female, for which the most important symbol of happiness is a life full of adventures and travel, and the most important values are personal goodness and tenderness. The desire to donate a kidney to another person decreases with age and grows with life satisfaction. Trial registration: ClinicalTrials.gov (ID: NCT04789122).

Willingness of caregivers to donate a kidney to a patient with end-stage renal disease: Findings from four dialysis providing health facilities in Uganda

Most patients with end-stage renal disease (ESRD) benefit from a kidney transplant but there is limited information from developing countries like Uganda about the willingness of caregivers for patients with end-stage kidney disease to donate a kidney. In this cross-sectional study, we examined the magnitude and factors associated with the willingness of caregivers to donate a kidney to their patient with ESRD in Kampala, Uganda. The study was conducted at four health facilities that provide kidney dialysis in Kampala, Uganda. We used a structured questionnaire to interview caregivers for patients with ESRD. Caregivers who reported they would consider donating a kidney to a patient with ESRD were considered willing and the rest as unwilling. We summarized data using descriptive statistics and used an adjusted prevalence risk ratio (aPRR) from a generalized linear model to establish factors independently associated with willingness to donate.We enrolled 125 participants with a mean age of 32.3±9.8 years and found 68 (54.4%) participants were willing to donate a kidney for transplant. Willingness to donate a kidney was more likely among older caregivers namely those aged 25-34 years (aPRR, 1.15; 95% CI, 1.01-1.31) and ≥35 years (aPRR 1.16; 95% CI, 1.05-1.29) compared to those aged 18-24 years, females compared to males (aPRR, 1.30; 95% CI, 1.19-1.42), those with a positive attitude towards organ donation (aPRR, 1.24; 95% CI, 1.13-1.36), and when organ kidney donation was permissible by the participant's religious faith (aPRR, 1.11; 95% CI, 1.01-1.22). Conversely, willingness to donate a kidney was less likely when the family did not approve of kidney donation (aPRR, 0.80; 95% CI, 0.71-0.90). We concluded that more than half of caregivers to patients with ESRD are willing to donate a kidney for transplant. To improve the willingness of caregivers to patients with ESRD in donating a kidney, the social, religious, and personal barriers to kidney donation may need to be addressed.

Does Having a Relative in Dialysis Therapy Affect Attitudes Toward Kidney Donating?

CONTEXT

The majority of kidney transplants in Turkey are performed from live donors and from those among first-degree relatives.

OBJECTIVE

To compare the view points and the attitudes of individuals who have relatives undergoing dialysis toward kidney donation treatment with those who do not.

DESIGN

The study was designed as a descriptive study, which used simple random sampling.

SETTING

The sample consisted of 204 individuals, divided into 2 groups: those whose relatives underwent dialysis treatment (group A, n = 106) and those whose relatives did not (group B, n = 98).

RESULTS

The means of the total points obtained in "Kidney Donation Attitude Inventory" (KDAI) by individuals in group A were statistically significantly higher than those obtained by individuals in group B ( P = .001). Although there was a statistically significant difference in the educational status, status of willing to donate their kidneys and being a relative of an individual awaiting a kidney transplant, and the mean total points obtained from the KDAI between the groups ( P < .05), no statistically significant difference was determined between the means of the obtained total points and the gender and the duration of dialysis treatment ( P > .05).

CONCLUSION

The attitudes of the relatives of individuals undergoing dialysis treatment toward kidney donation were determined to be more positive.

Policy options for increasing the supply of transplantable kidneys in Singapore

Kidney transplantation is the preferred treatment for eligible end-stage renal disease patients. However, the supply of donated kidneys has been consistently insufficient to meet the transplantation requirements of the population. In this paper, I discuss the feasibility of several policy options that engage potential donors or key individuals in a Singapore context, including financial and non-financial incentives for deceased/living organ donors and their families, improving actualisation rates of both donation after brain death, donation after cardiac death through quality improvement programmes and remuneration schemes, and a media platform for directed organ donation. I conclude by highlighting the most feasible policies to be considered.

Predictors of low estimated glomerular filtration rate after living kidney donation in a Southeast Asian population from Singapore

AIM

Post-donation kidney function has not been well characterized in the Southeast Asian population. We studied a retrospective cohort of 174 living kidney donors at Singapore General Hospital between 1976 and 2012, evaluated patterns of change in kidney function using quantile regression analysis and investigated for predictors of low estimated glomerular filtration rate (eGFR) < 60 mL/min per 1.73m² . Median follow-up time (range) was 7.8 (0.1-33.8) years following donor nephrectomy.

RESULTS

Of the donors, 43.1% regained 75% or more of pre-nephrectomy eGFR after 5 years post-donation; 9.8% exhibited 100% recovery to pre-nephrectomy eGFR. High pre-nephrectomy eGFR was protective for risk of low post-donation eGFR, with a 6% risk reduction for each unit increase in pre-nephrectomy eGFR (odds ratio, 0.94; 95% confidence interval, 0.91-0.97; P = 0.002). This relationship was stronger in the short term (>6 months to < 5 years) than medium to long term (5 years or longer) (interaction P = 0.052).

CONCLUSION

In general, kidney function is well preserved following kidney donation in Southeast Asian donors. Pre-nephrectomy eGFR is a good predictor of post-donation eGFR, especially in the short-term.

From potential donor to actual donation: does socioeconomic position affect living kidney donation? A systematic review of the evidence

Evidence from Europe, Australia and the United States demonstrates that socioeconomically deprived individuals with advanced chronic kidney disease are less likely to receive a living kidney transplant compared with less deprived individuals. This systematic review focuses on how socioeconomic position (SEP) may influence hypothetical and actual living kidney donors and where appropriate, summarizes the quantitative evidence.In the general population, a higher SEP appears to be associated with an increased 'hypothetical' willingness to be a living kidney donor but with marked heterogeneity in the absolute differences (I = 95.9%, P < 0.001). In a commercial setting, lower SEP motivates people to donate. Outside of this setting, there is no evidence of discordance in the SEP of donors and recipients that would suggest undisclosed financial exchange. There is evidence for a complex interaction between SEP and other variables, such as ethnicity, sex, and the national economic climate. Some evidence suggests that measures to remove financial disincentives to donation are associated with an increase in living donation rates. Future research needs to study how SEP impacts the potential donor population from willingness to donate, progression through donor assessment to actual donor nephrectomy.

Long-term quality of life after living kidney donation

BACKGROUND

The supply of deceased donor kidneys available for transplantation is not sufficient to meet the demand. Despite a low rate of complications for donors and superior outcomes for recipients, living kidney donation (LKD) is on the decline for reasons that remain unclear.

METHODS

We performed a retrospective review and analysis of living kidney donors (LDs) who underwent donor nephrectomy between January 1, 2000 and December 31, 2010. Candidates who were excluded from LKD were identified as control subjects (CSs). LDs and CSs were invited to voluntarily undergo a quality of life assessment using Short Form 12 v1.0 Questionnaire (SF-12) and an addendum questionnaire (AQ). The SF-12 and AQ were administered by telephone. Statistical analysis of the results was performed to obtain the SF-12 physical component score (PCS), SF-12 mental component score (MCS), and the AQ score. PCS and MCS for the general population were obtained from the 1998 National Survey of Functional Health Status.

RESULTS

During the study period, 83 LDs and 116 CSs were interviewed. LDs were noted to have higher PCS (54.1 vs 49.6) and MCS (55.7 vs 49.4) compared with the general population. Ninety-nine percent of LDs believed that their quality of life did not decrease after LKD; 21.7% reported experiencing complications. Half of the LDs (48%) reported missing 1 day of work for evaluation; 71% of LDs reported missing at least 4 weeks of work after LKD. Nearly all LDs (99%) would undergo donation again. Fifty-two percent of LDs reported adhering to the recommended 2-year follow-up schedule with the transplantation team; 87% of LDs reported seeing their primary care physician.

CONCLUSION

LDs are physically and mentally healthier after LKD compared to the general population. Most donors miss at least 1 month of work for LKD and undergo some form of post-donation monitoring. Despite this commitment, LKD is a very satisfying experience.

Public awareness and attitudes to living organ donation: systematic review and integrative synthesis

BACKGROUND

The deceased-donor organ shortage has driven widespread adoption of living-donor transplantation. Yet, public views on living donation are not well understood. This study aims to synthesize studies on public awareness and attitudes toward living organ donation.

METHODS

Electronic databases and reference lists were searched to September 2012. Summary estimates from survey data were obtained by random effects meta-analysis. Qualitative descriptive synthesis of each study was performed.

RESULTS

Forty-seven studies involving 34,610 respondents were included. The proportion of respondents aware of living organ donation was 76.7% (4 studies, n=3248; 95% confidence interval, 46.2%-97.0%; I=99.7%). The majority were in favor of living directed donation (85.5% (11 studies, n=15,836; 95% confidence interval, 81.6%-89.6%; I=98%), with recipient and community benefit as the rationale provided. However, barriers included fear of surgical and health risks, lack of knowledge, respect for cultural norms, financial loss, distrust in hospitals, and avoiding recipient indebtedness. The public voiced concern about possible risks or an obligatory pressure exerted on the donor. Many supported reimbursement for out-of-pocket expenses, paid leave, wait-listing priority, health insurance, and donor acknowledgment. There was strong opposition to financial incentives, which they believed risked exploitation and inequity and diminished voluntary altruistic donation.

CONCLUSIONS

The public is generally supportive of living donation and articulated important equity and ethical considerations for protecting the health and safety of living donors. This supports increased public engagement and strengthening of a shared view among professionals and the public in living donation practice and policy.
