Intentions of becoming a living organ donor among Hispanics: a theory-based approach exploring differences between living and nonliving organ donation

Effects of portraying an innocent versus non-innocent identified victim on intentions to donate organs post-mortem

The need for more people to register as organ donors is a pressing concern. This preregistered experiment examined whether portraying a patient in need of an organ transplant as leading a healthy lifestyle (an "innocent victim") can serve to increase people's intentions to register as post-mortem organ donors. Participants not previously registered as organ donors (N = 348) were randomly assigned to an innocent identified victim, non-innocent identified victim, or statistical victims condition. The identified victim was a 42 year-old woman in need of a liver transplant. The experimental manipulation produced marginally significant effects on self-reported intentions to register as an organ donor. Moreover, participants in the innocent victim condition were more likely relative to those in the non-innocent victim condition to sign up on an e-mail list to receive additional information about organ donation.

Vested Interest Theory as a Framework for Understanding Anthropogenic Climate Change Risk Perceptions

Climate change due to anthropogenic activities is contributing to the systematic warming of Earth. A warming planet represents an existential threat to humanity, contributing to the increased frequency and magnitude of multiple natural hazards. The UN's Intergovernmental Panel on Climate Change (IPCC) notes that time is running out to create meaningful change to avert climate-related consequences. This research posits Vested Interest Theory (VIT) as a potentially useful framework for assessing attitudes and risk perceptions associated with anthropogenic climate change (ACC). Vested Interest Theory mediates the attitude-behavior relationship where highly vested individuals are more likely to behave in attitudinally-consistent ways. Vestedness is conceptualized as five distinct and observable variables: salience, certainty, immediacy, self-efficacy, and response-efficacy. To test VIT's efficacy in this context, a survey was conducted with participants crowdsourced from Amazon's Mechanical Turk platform (N = 1053). Participants responded to items designed to measure their individual vestedness in ACC consequences, risk perceptions, and behavioral intentions. This initial investigation shows that VIT's constituent variables predict consequential amounts of observed variance in critical variables including risk perception, perceived event severity, and behavioral intentions related to ACC hazard mitigation. The results support the use of VIT as a framework for understanding attitude-behavior relationships associated with ACC mitigation. Based on these findings, we argue that VIT can also serve as a valuable message design framework to motivate ACC-related mitigation actions.

A machine-learning approach to estimating public intentions to become a living kidney donor in England: Evidence from repeated cross-sectional survey data

Background

Living kidney organ donors offer a cost-effective alternative to deceased organ donation. They enable patients with life-threatening conditions to receive grafts that would otherwise not be available, thereby creating space for other patients waiting for organs and contributing to reducing overall waiting times for organs. There is an emerging consensus that an increase in living donation could contribute even more than deceased donation to reducing inequalities in organ donation between different population sub-groups in England. Increasing living donation is thus a priority for National Health Service Blood and Transplant (NHSBT) in the United Kingdom.

Methods

Using the random forest model, a machine learning (ML) approach, this study analyzed eight waves of repeated cross-sectional survey data collected from 2017 to 2021 (n = 14,278) as part of the organ donation attitudinal tracker survey commissioned by NHSBT in England to identify and help predict key factors that inform public intentions to become living donors.

Results

Overall, around 58.8% of the population would consider donating their kidney to a family member (50.5%), a friend (28%) or an unknown person (13.2%). The ML algorithm identified important factors that influence intentions to become a living kidney donor. They include, in reducing order of importance, support for organ donation, awareness of organ donation publicity campaigns, gender, age, occupation, religion, number of children in the household, and ethnic origin. Support for organ donation, awareness of public campaigns, and being younger were all positively associated with predicted propensity for living donation. The variable importance scores show that ethnic origin and religion were less important than the other variables in predicting living donor intention.

Conclusion

Factors influencing intentions to become a living donor are complex and highly individual in nature. Machine learning methods that allow for complex interactions between characteristics can be helpful in explaining these decisions. This work has identified important factors and subgroups that have higher propensity for living donation. Interventions should target both potential live donors and recipients. Research is needed to explore the extent to which these preferences are malleable to better understand what works and in which contexts to increase live organ donation.

International Population Study in Spain, Cuba, and the United States of Attitudes Toward Organ Donation Among the Cuban Population

Cuban immigrants constitute an important group in both the United States and Spain, with different behaviors toward organ donation having been described among the different Latin American nationalities. We analyzed the attitude toward organ donation among the Cuban populations in Cuba, Spain, and Florida. The study population was Cuban immigrants over 15 years of age residing in Cuba, Spain, and Florida, with samples randomly stratified by age and sex. A validated questionnaire on psychosocial aspects of organ donation (PCID-DTO Rios) was used. Census was used as the sampling base in all 3 countries; however, additionally, in Spain and the United States (Florida), we sought the support of immigration support associations to determine the Cuban population without legal documentation. The questionnaire was completed anonymously and self-administered. The completion rate of the study was 74% (4123/5574) among 424 surveyed in Spain, 1224 in Florida, and 2475 in Cuba. The attitude in favor of donating their own organs upon death was 60.6% of those surveyed in Spain, 37.6% in Florida, and 68.9% in Cuba, or 58% of the global sample. Multivariate analysis showed that country of residence was an independent factor associated with attitude toward organ donation (odds ratio, 1.929). Other factors associated with attitude were sex, educational level, performance of prosocial activities, knowledge of the brain death concept, religion, the couple's opinion toward donation, fear of mutilation after donation, and attitude toward manipulation of the body after death. The attitude toward organ donation among Cubans in their country of origin and immigrants in Spain was similar, being significantly different from those who emigrate to Florida, where the attitude is much less favorable.

It’s all relative: Increasing organ donor registration intentions by maximizing family-relevant vested interest

Guided by vested interest theory, the impact of educating potential organ donors about the beneficial experiences afforded to families of deceased donors was assessed. Participants were informed about these benefits by taking a survey that asked them to indicate both their awareness, and the appeal, of numerous existing benefits (e.g. grief services). We employed a double-sided mixed design. Both the true experimental design and the quasi-experimental repeated assessment indicated increased registration intentions. Only the quasi-experimental design indicated significant attitude change. This study provides evidence supporting the potential utility of focusing interventions on the benefits afforded to donor families.

Utility of Theory to Explain Village Doctors' Willingness to Treat People Living with HIV in Rural China

Stigma against people living with HIV in China is common, not only among the general public but also among Chinese health-care providers, impacting their ability to provide quality HIV treatment and care. HIV stigma may be particularly common in rural areas of China, where village doctors (i.e., "barefoot doctors") have limited medical training yet are charged with providing frontline care for much of China's rural population. Therefore, the present study aims to use communication and behavioral theory to better understand Chinese village doctors' beliefs about HIV, including their willingness to become involved in HIV treatment and care. In collaboration with the Behai Centers for Disease Control, we surveyed 228 village doctors in rural China to learn about their experiences in providing HIV treatment and care. We then applied a hybrid theoretical model, combining variables from the Situational Theory of Publics and the Theory of Reasoned Action, to explain providers' communication, attitudes, and behaviors. Findings suggest that enhanced information activity about HIV may increase providers' self-efficacy in caring for HIV patients and yield more positive attitudes towards caring for people living with HIV. Theoretical and practical implications are discussed.

Application of vested interest theory to prevention of non-medical prescription stimulant and marijuana use: Unforeseen benefits of attitude-behavior inconsistency

BACKGROUND

Vested interest (VI) has been found to enhance attitude-behavior consistency in several contexts. With an eye toward a potentially novel method of prevention (i.e., reducing perceived VI to minimize attitude-behavior consistency among those positively inclined toward psychotropic substance use), the current investigation explores whether VI moderates attitude-intention consistency regarding nonmedical use of prescription stimulants (NUPS) and marijuana.

METHODS

Emphasizing prevention, the study focused exclusively on non-users. Study 1a assessed college students (N = 310) attitudes, VI, and intentions regarding NUPS among those with no prior NUPS experience. Respondents were sampled using Amazon's Mechanical Turk. Study 1b investigated marijuana-abstinent college students (N = 93), recruited from college classrooms.

RESULTS

The pattern of results was similar in both studies. In addition to an association between attitudes and VI, analysis revealed main effects for attitudes and VI on substance use intentions. Moreover, VI moderated the attitude-intention relationship (p < .01). Attitudes were most weakly associated with usage intentions when perceptions of VI were low (vs. moderate or strong).

CONCLUSION

Results of these studies replicate and expand prior findings relating VI to drug use, and suggest a potential path for future prevention efforts. The current study was cross-sectional, however if the causal pathways are as theorized, an intervention that reduces subjective VI has the potential to reduce positive attitudes while simultaneously reducing the influence of favorable attitudes on intentions.

Emigration From Puerto Rico to Florida: Multivariate Analysis of Factors That Condition Attitudes of the Puerto Rican Population Toward Organ Donation for Transplant

BACKGROUND

The Puerto Rican population represents one of the largest immigration groups in Florida, and this has an impact on the organ transplant donation process. Our aim was to analyze attitudes toward organ donation among Puerto Ricans who currently reside in the state of Florida (USA).

METHODS

The population screened consisted of individuals >15 years old, who were born in Puerto Rico, living in Florida, and awaiting organs for transplant. All participants completed the "PCID-DTO Rios" questionnaire. Random selection was done according to stratification. Support from immigration associations in Spain was needed for advice on the locations of potential respondents. Study participation was anonymized and self-administered.

RESULTS

There were 259 respondents, 37% (n = 95) were in favor of donation, 36% (n = 93) were against donation, and 27% (n = 71) were undecided. The variables associated with these attitudes were: age (P = .017); civil status (P = .021); level of education (P < .001); previous experience with donation and transplant (P < .001); attitude toward organ donation of a relative (P < .001); carrying out pro-social activities (P < .001); discussing the issue of transplant with the family (P < .001) or couple (P < .001); attitude toward incineration (P < .001), burial (P < .001), and autopsy (P < .001); fear of mutilation after donation (P < .001); and religious beliefs (P < .001). In the multivariate study, it remained an independent variable to have discussed the issue at the family level (odds ratio = 11.627; P = .009).

CONCLUSION

The Puerto Rican study population residing in Florida has an unfavorable attitude toward organ donation.

A complex culturally targeted intervention to reduce Hispanic disparities in living kidney donor transplantation: an effectiveness-implementation hybrid study protocol

BACKGROUND

The shortage of organs for kidney transplantation for patients with end-stage renal disease (ESRD) is magnified in Hispanics/Latin Americans in the United States. Living donor kidney transplantation (LDKT) is the treatment of choice for ESRD. However, compared to their representation on the transplant waitlist, fewer Hispanics receive a LDKT than non-Hispanic whites. Barriers to LDKT for Hispanics include: lack of knowledge, cultural concerns, and language barriers. Few interventions have been designed to reduce LDKT disparities. This study aims to reduce Hispanic disparities in LDKT through a culturally targeted intervention.

METHODS/DESIGN

Using a prospective effectiveness-implementation hybrid design involving pre-post intervention evaluation with matched controls, we will implement a complex culturally targeted intervention at two transplant centers in Dallas, TX and Phoenix, AZ. The goal of the study is to evaluate the effect of Northwestern Medicine's® Hispanic Kidney Transplant Program's (HKTP) key culturally targeted components (outreach, communication, education) on Hispanic LDKT rates over five years. The main hypothesis is that exposure to the HKTP will reduce disparities by increasing the ratio of Hispanic to non-Hispanic white LDKTs and the number of Hispanic LDKTs. We will also examine other process and outcome measures including: dialysis patient outreach, education session attendance, marketing efforts, Hispanic patients added to the waitlist, Hispanic potential donors per potential recipient, and satisfaction with culturally competent care. We will use mixed methods based on the Promoting Action on Research Implementation in Health Services (revised PARIHS) and the Consolidated Framework for Implementation Research (CFIR) frameworks to formatively evaluate the fidelity and innovative adaptations to HKTP's components at both study sites, to identify moderating factors that most affect implementation fidelity, and to identify adaptations that positively and negatively affect outcomes for patients.

DISCUSSION

Our study will provide new knowledge about implementing culturally targeted interventions and their impact on reducing health disparities. Moreover, the study of a complex organizational-level intervention's implementation over five years is rare in implementation science; as such, this study is poised to contribute new knowledge to the factors influencing how organizational-level interventions are sustained over time.

The influence of beliefs on organ donation intention

Purpose

Recent technological developments in healthcare have enabled an increased number of organ transplantation surgeries. At the same time, there is an increase in the number of people awaiting organ transplant, coupled with the difficulty in donation. To bridge this gap, this study aims to propose to evaluate the effect of three types of beliefs (clinical beliefs, financial incentive beliefs and beliefs on the social benefits of altruism and solidarity) on the intention to donate organs. Moreover, this paper uses the attitudes in relation to donation to explain the effect of these beliefs on the intention to donate organs.

Design/methodology/approach

The research was conducted using a survey of 422 Brazilian participants and a mediation analysis to test the mediation hypotheses.

Findings

The results suggest that the effect of three types of beliefs (clinical, economic order and social solidarity) influence the intention to donate organs indirectly through the formation of attitudes concerning organ donation.

Research limitations/implications

This article contributes to the understanding of the formation of organ donation intentions and the role of different types of beliefs in the formation of such intentions.

Originality/value

The findings extend the discussions regarding the role of beliefs in the formation of attitudes and intentions of organ donation and have significant value in creating public policies that further promote organ donation.

A Culturally Targeted Website for Hispanics/Latinos About Living Kidney Donation and Transplantation: A Randomized Controlled Trial of Increased Knowledge

BACKGROUND

Hispanics/Latinos receive disproportionately fewer living donor kidney transplantations (LDKTs) than non-Hispanic whites. We conducted a multisite, randomized controlled trial to evaluate the efficacy of exposure to a bilingual, culturally targeted website, Infórmate, for increasing Hispanics' knowledge about LDKT.

METHODS

Hispanic patients initiating transplant evaluation and their family/friends at 2 transplant centers were randomized to view Infórmate before attending routine transplant education sessions; usual care controls only attended education sessions. All participants completed a pretest; website participants also completed a posttest immediately after viewing Infórmate. All participants completed a 3-week telephone follow-up test. Random effects linear regression of 3-week knowledge scores tested the significance of website exposure after adjusting for clustering within families and controlling for pretest scores and covariates.

RESULTS

Two hundred-eighty-two individuals participated (81% patient participation rate). Website exposure was associated with a mean 21.7% same day knowledge score increase between pretest and posttest (P < 0.001). At 3 weeks, website participants' knowledge scores remained 22.6% above the pretest; control scores increased to 11.8% (P = 0.0001). Regression results found that website participants were associated with a 10.0% greater knowledge score at 3-week follow-up (P < 0.0001). Most website participants (92.6%) plan to return to Infórmate in the future.

CONCLUSIONS

Our culturally targeted website increased participants' knowledge about LDKT above and beyond transplant education and should supplement transplant center education for Hispanics. When considered at the population level, Infórmate could have a great impact on knowledge gains in this underserved population disproportionately affected by kidney disease.

Google analytics of a pilot mass and social media campaign targeting Hispanics about living kidney donation

BACKGROUND

The number of patients waiting for a kidney transplant surpasses available organs. Living donor kidney transplantation (LDKT) can expand the organ pool. However, Hispanics have lower rates of LDKT than non-Hispanic whites, largely due to a lack of awareness and knowledge about LDKT as a treatment option. To reduce this disparity about LDKT, Northwestern University faculty in partnership with the National Kidney Foundation of Illinois, developed a website culturally targeted to Hispanics about LDKT, called Infórmate.

OBJECTIVE

This paper describes a pilot mass media campaign about LDKT which leveraged Infórmate to provide additional education about LDKT targeting the Hispanic public in Chicago, IL. We report the impact of the campaign on visits to Infórmate.

METHODS

The mass media campaign was conducted in Chicago, IL from July 16, 2015 to January 17, 2016 in two waves. The campaign used traditional media, online media, and community-based venues. The campaign's bilingual (Spanish and English) messaging addressed key topics about kidney disease and LDKT, and included a call to action to visit Infórmate to learn more. Google Analytics was used to evaluate the effectiveness of the campaign's call to action by measuring the number of visits to Infórmate, visit duration, bounce rate, number of pages visited, pages most often visited, user demographics, and media channel.

RESULTS

Infórmate received an average of 1466 sessions per month during the entire campaign period, with a 16.7% return rate. Sessions and visitors increased during the entire campaign period compared to the pre- and post- campaign periods. Visits lasted an average of 1:26 min, with a bounce rate of 73.9% per session. Users visited an average of 1.93 pages, and the pages with the most views were Immigrant Issues and Financial Issues. Most sessions during this period occurred in the USA (69.57%) out of 100 countries, and in the city of Chicago (13.37%). Sessions were mostly conducted by men (54.1%) and people ages 18-34 (61%). Visitors accessed Infórmate primarily through their desktop computer (53.1%), and by typing the website address directly into their browser (32.78%).

CONCLUSIONS

Our findings suggest that our pilot mass media campaign's call to action was effective in increasing the Hispanic public's traffic to Infórmate. Google Analytics data can help to strategize future campaign messages and outlets. Future research should assess whether a theoretically-driven mass media campaign increases the Hispanic public's knowledge about LDKT, and increases rates of LDKT.

Does Donor Status, Race, and Biological Sex Predict Organ Donor Registration Barriers?

PURPOSE

The purpose of the current study was to examine differences among bodily integrity, disgust, medical mistrust, and superstition among African Americans, Caucasians, and Latinos; females and males; and registered organ donors and non-registered potential donors.

METHODS

A random digit dialing phone survey was utilized to garner information pertaining to organ donation beliefs among African American (n = 200), Caucasian (n = 200), and Latino (n = 200) Chicago residents. More specifically, participants responded to measures of bodily integrity, disgust, medical mistrust, and superstition, organ donor registration status, among others.

RESULTS

The results indicated that African American and Latino participants were less likely to be registered organ donors than Caucasians (p < .001). In general, females maintained fewer barriers than males with respect to bodily integrity (p < .05), disgust (p = .01), and superstition (p = .01). With respect to organ donation barriers, bodily integrity (p < .0001) emerged as a central concern among those surveyed.

CONCLUSION

This study highlights the significance of audience segmentation when promoting posthumous organ and tissue donation. Specifically, the results stress the importance of constructing distinct messages to non-registered potential donors compared to messages delivered to registered donors. Moreover, different barriers surfaced among females and males as well as among African American, Caucasian, and Latino residents. It is clear that a one size fits all approach will likely not work when promoting organ and tissue donation.

Nonmedical use of prescription stimulants in college students: Attitudes, intentions, and vested interest

INTRODUCTION

Research on vested interest theory (VIT) indicates that the importance and hedonic relevance of attitudes moderates the link between attitudes and attitude-congruent behavior. Though largely untested in prevention research, this relationship may prove crucial in determining the success or failure of prevention efforts. The current study was designed to determine if subjectively perceived vested interest maximized the association between attitudes and intentions regarding the nonmedical use of prescription stimulants (NUPS).

METHODS

A cross-sectional survey was conducted with college student respondents (N=162) using Amazon's MTurk. Participant age ranged from 19 to 49years old. A subsample analysis (n=129) was also conducted with younger respondents, as the typical college student is usually under the age of 30.

RESULTS

Four-step hierarchical regression analysis indicated that both attitudes and perceived vested interest were significantly associated with NUPS behavioral intentions (p<.001). Further, vested interest moderated the relationship between stimulant-related attitudes and usage intentions (p<.001). Attitudes were significantly associated with intentions of moderately and highly vested respondents (p<.001), but not those of participants expressing low levels of perceived vested interest.

CONCLUSIONS

Findings support the proposition that vested interest may be a useful target for attenuating NUPS. Rather than attempting to weaken positive attitudes toward NUPS, campaigns may prove more successful if designed to convince receivers that NUPS is not in their best interest.

An Effort to Increase Organ Donor Registration Through Intergroup Competition and Electronic Word of Mouth

The effort to increase Web organ donation registrations in Michigan by enhancing 2 types of university campaigns with social media strategies informed by social identity theory is the focus of this research. The two campaigns focused on either ingroup or rivalry outgroup social identification, and each was enhanced with individually focused social media in the first year of the campaign and with electronic word of mouth in Year 2 of the campaign. Results indicated that individually focused social media such as Facebook ads worked well in rivalry campaigns (in which registrations increased two times over baseline) but not in ingroup identification campaigns (in which registrations decreased significantly over baseline when ads were introduced in the first year of each type of campaign). Electronic word-of-mouth strategies worked well in both ingroup identification campaigns (in which registrations increased two times over baseline) and rivalry campaigns (in which registrations rose almost eight times over baseline, when strategies were introduced in the second year of each type of campaign).

Hispanic/Latino Disparities in Living Donor Kidney Transplantation: Role of a Culturally Competent Transplant Program

Hispanic Americans face disparities in access to kidney transplantation, particularly living donor kidney transplantation (LDKT). This study compared characteristics of LDKT recipients before and after implementing the Hispanic Kidney Transplant Program (HKTP) at Northwestern Medicines (NM) and other centers.

METHODS

The NM HKTP, initiated in December 2006, delivers culturally and linguistically competent and congruent care. Program-specific data were used to compare the mean ratios of Hispanic to non-Hispanic white LDKTs between pre-HKTP (2001-2006) and post-HKTP (2008-2013), and to compare the characteristics of NM's adult LDKT patients between pre-HKTP and post-HKTP. The same ratio was calculated for transplant centers in regions with a significant Hispanic population (≥25%) and performing in the top tertile of total LDKT volume in the pre-HKTP period. The number of Hispanic and non-Hispanic white patients added to the waiting list were compared between pre-HKTP (2001-2006) and post-HKTP (2008-2013) as a proxy for increased patient referrals and a pathway by which the HKTP may increase LDKTs.

RESULTS

The ratio of Hispanic to non-Hispanic white LDKTs significantly increased by 70% after the implementation of NM's HKTP (pre-HKTP mean = 0.20, post-HKTP mean = 0.34; P= 0.001). None of the other transplant centers experienced a similar increase in their ratio of Hispanic to non-Hispanic white LDKTs. The NM waiting list additions grew by 91% among Hispanics, but grew only 4% for non-Hispanic whites.

CONCLUSIONS

These data suggest that the development and implementation of a culturally congruent transplant program can positively affect Hispanic LDKT and thereby reduce Hispanics disparities in LDKT rates. Further studies are needed to prospectively evaluate the generalizability of implementing such culturally competent interventions at other transplant programs.

An examination of three theoretical models to explain the organ donation attitude--registration discrepancy among mature adults

An inconsistency in the research indicates positive attitudes toward organ donation do not map reliably onto organ donor registrations. Various models have sought to explain this inconsistency and the current analysis formally compared three models: the Bystander Intervention Model (BIM), the Organ Donor Model (ODM), and Vested Interest Theory (VIT). Mature (N = 688) adults between the ages of 50 to 64 years completed surveys related to organ donation. Results revealed that VIT accounted for the most variance in organ donation registrations followed by the BIM and ODM. The discussion emphasizes the importance of employing theories to explain a phenomenon as well as the practical implications of the findings.

Living Donor Kidney Transplantation: Overcoming Disparities in Live Kidney Donation in the US--Recommendations from a Consensus Conference

Despite its superior outcomes relative to chronic dialysis and deceased donor kidney transplantation, live donor kidney transplantation (LDKT) is less likely to occur in minorities, older adults, and poor patients than in those who are white, younger, and have higher household income. In addition, there is considerable geographic variability in LDKT rates. Concomitantly, in recent years, the rate of living kidney donation (LKD) has stopped increasing and is declining, after decades of consistent growth. Particularly noteworthy is the decline in LKD among black, younger, male, and lower-income adults. The Live Donor Community of Practice within the American Society of Transplantation, with financial support from 10 other organizations, held a Consensus Conference on Best Practices in Live Kidney Donation in June 2014. The purpose of this meeting was to identify LKD best practices and knowledge gaps that might influence LDKT, with a focus on patient and donor education, evaluation efficiencies, disparities, and systemic barriers to LKD. In this article, we discuss trends in LDKT/LKD and emerging novel strategies for attenuating disparities, and we offer specific recommendations for future clinical practice, education, research, and policy from the Consensus Conference Workgroup focused on disparities.

Your Path to Transplant: a randomized controlled trial of a tailored computer education intervention to increase living donor kidney transplant

BACKGROUND

Because of the deceased donor organ shortage, more kidney patients are considering whether to receive kidneys from family and friends, a process called living donor kidney transplantation (LDKT). Although Blacks and Hispanics are 3.4 and 1.5 times more likely, respectively, to develop end stage renal disease (ESRD) than Whites, they are less likely to receive LDKTs. To address this disparity, a new randomized controlled trial (RCT) will assess whether Black, Hispanic, and White transplant patients' knowledge, readiness to pursue LDKT, and receipt of LDKTs can be increased when they participate in the Your Path to Transplant (YPT) computer-tailored intervention.

METHODS/DESIGN

Nine hundred Black, Hispanic, and White ESRD patients presenting for transplant evaluation at University of California, Los Angeles Kidney and Pancreas Transplant Program (UCLA-KPTP) will be randomly assigned to one of two education conditions, YPT or Usual Care Control Education (UC). As they undergo transplant evaluation, patients in the YPT condition will receive individually-tailored telephonic coaching sessions, feedback reports, video and print transplant education resources, and assistance with reducing any known socioeconomic barriers to LDKT. Patients receiving UC will only receive transplant education provided by UCLA-KPTP. Changes in transplant knowledge, readiness, pros and cons, and self-efficacy to pursue LDKT will be assessed prior to presenting at the transplant center (baseline), during transplant evaluation, and 4- and 8-months post-baseline, while completion of transplant evaluation and receipt of LDKTs will be assessed at 18-months post-baseline. The RCT will determine, compared to UC, whether Black, Hispanic, and White patients receiving YPT increase in their readiness to pursue LDKT and transplant knowledge, and become more likely to complete transplant medical evaluation and pursue LDKT. It will also examine how known patient, family, and healthcare system barriers to LDKT act alone and in combination with YPT to affect patients' transplant decision-making and behavior. Statistical analyses will be performed under an intent-to-treat approach.

DISCUSSION

At the conclusion of the study, we will have assessed the effectiveness of an innovative and cost-effective YPT intervention that could be utilized to tailor LDKT discussion and education based on the needs of individual patients of different races in many healthcare settings.

Barriers to living donation among low-resource Hispanics

Hispanics are disproportionately affected by renal failure. Although living donation has been heralded as a potential means for alleviating the need for transplantable kidneys, a nuanced understanding of the obstacles faced by Hispanics is necessary. In our study, we conducted focus groups with 28 first-generation Spanish-dominant Hispanic renal patients. Although some of the barriers that emerged were akin to those reported in previous research (e.g., a lack of knowledge about the process), others were unique. Rarely chronicled barriers include the disqualification of family members because of medical issues, potential donors being unable to miss work, disqualification of family members who are undocumented, concern that potential donors cannot support their family if they donate, and declining social support because of illness. The interaction among this constellation of barriers makes living donation particularly difficult among this population. Investigations focused on the unique barriers faced by these low-resource individuals are warranted.

Hispanic/Latino concerns about living kidney donation: a focus group study

CONTEXT

Given the shortage of kidneys for transplant, living kidney donation (LKD) is increasingly used to expand the organ donor pool. Although Hispanics/Latinos need disproportionately more kidney transplants, they receive a smaller proportion of living donor kidney transplants than other ethnic/racial groups.

OBJECTIVE

To assess Hispanics' awareness, perceptions, misconceptions, cultural beliefs, and values about and barriers to LKD.

DESIGN

Nine focus groups were conducted with 76 adult Hispanics in Chicago, Illinois, between January and March 2012.

PARTICIPANTS

Focus groups included kidney transplant recipients, living kidney donors, dialysis patients, and the general Hispanic public.

RESULTS

Several themes emerged as perceived barriers to LKD. Many participants identified knowledge deficits about LKD, expressing uncertainty about the differences between LKD and deceased donation, and whether kidney disease simultaneously afflicts both kidneys. Many believed that donors experience dramatically shorter life expectancies, are unable to have children, and are more susceptible to kidney disease after donating. Recipients and donors reported that family members were involved in discussions about the donor's decision to donate, with some family members discouraging donation. Financial barriers cited included fear of becoming unable to work, losing one's job, or being unable to pay household bills while recovering. Participants also identified logistic barriers for undocumented immigrants (eg, the inability to obtain government insurance for transplant candidates and uncertainty about their eligibility to donate). Donors desired information about optimizing self-care to promote their remaining kidney's health. Culturally competent interventions are needed to redress Hispanics' knowledge deficits and misconceptions and reduce LKD disparities among Hispanics.

Culturally competent transplant program improves Hispanics' knowledge and attitudes about live kidney donation and transplant

CONTEXT

Hispanics receive disproportionately fewer live donor kidney transplants than non-Hispanic whites. Increasing Hispanics' knowledge and changing attitudes about live kidney donation may reduce these disparities.

OBJECTIVE

To evaluate the effectiveness of culturally and linguistically competent educational sessions delivered through Northwestern University's Hispanic Transplant Program.

DESIGN

Baseline and postsession questionnaires were used to evaluate changes in patients' and family members' knowledge and attitudes toward live kidney donation and program satisfaction. Knowledge items related to live kidney donation were scaled, and changes in scores were evaluated via a paired t test. Multiple regression analysis of follow-up knowledge scores controlled for baseline scores was used to estimate the effects of patients' and families' sociodemographic characteristics. Changes in attitude items, including comfort with exploring live kidney donation, were analyzed with χ2 tests.

RESULTS

One-hundred thirteen patients and family members completed surveys before and after an education session. Respondents' knowledge about live kidney donation and transplant increased significantly (P<.001) between baseline and after the session. Patients' attitudes toward live kidney donation became more favorable (P< .02), as did family members' attitudes toward being a donor (P < .001) after participating in the program. All respondents reported high levels of satisfaction with the program and preferences for culturally congruent care.

CONCLUSIONS

The educational sessions provided by the Hispanic Transplant Program effectively addressed commonly shared Hispanic concerns about live kidney donation. Culturally congruent education increased Hispanic patients' and family members' knowledge and improved attitudes about live donor kidney transplants.

Donating blood and organs: using an extended theory of planned behavior perspective to identify similarities and differences in individual motivations to donate

Due to the critical shortage and continued need of blood and organ donations (ODs), research exploring similarities and differences in the motivational determinants of these behaviors is needed. In a sample of 258 university students, we used a cross-sectional design to test the utility of an extended theory of planned behavior (TPB) including moral norm, self-identity and in-group altruism (family/close friends and ethnic group), to predict people's blood and OD intentions. Overall, the extended TPB explained 77.0% and 74.6% of variance in blood and OD intentions, respectively. In regression analyses, common contributors to intentions across donation contexts were attitude, self-efficacy and self-identity. Normative influences varied with subjective norm as a significant predictor related to OD intentions but not blood donation intentions at the final step of regression analyses. Moral norm did not contribute significantly to blood or OD intentions. In-group altruism (family/close friends) was significantly related to OD intentions only in regressions. Future donation strategies should increase confidence to donate, foster a perception of self as the type of person who donates blood and/or organs, and address preferences to donate organs to in-group members only.

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.

Racial differences in determinants of live donor kidney transplantation in the United States

Few studies have compared determinants of live donor kidney transplantation (LDKT) across all major US racial-ethnic groups. We compared determinants of racial-ethnic differences in LDKT among 208 736 patients who initiated treatment for end-stage kidney disease during 2005-2008. We performed proportional hazards and bootstrap analyses to estimate differences in LDKT attributable to sociodemographic and clinical factors. Mean LDKT rates were lowest among blacks (1.19 per 100 person-years [95% CI: 1.12-1.26]), American Indians/Alaska Natives-AI/ANs (1.40 [1.06-1.84]) and Pacific Islanders (1.10 [0.78-1.84]), intermediate among Hispanics (2.53 [2.39-2.67]) and Asians (3.89 [3.51-4.32]), and highest among whites (6.46 [6.31-6.61]). Compared with whites, the largest proportion of the disparity among blacks (20%) and AI/ANs (29%) was attributed to measures of predialysis care, while the largest proportion among Hispanics (14%) was attributed to health insurance coverage. Contextual poverty accounted for 16%, 4%, 18%, and 6% of the disparity among blacks, Hispanics, AI/ANs and Pacific Islanders but none of the disparity among Asians. In the United States, significant disparities in rates of LDKT persist, but determinants of these disparities vary by race-ethnicity. Efforts to expand preESKD insurance coverage, to improve access to high-quality predialysis care and to overcome socioeconomic barriers are important targets for addressing disparities in LDKT.

The effect of depression on physician-patient communication among Hispanic end-stage renal disease patients

End-stage renal disease is associated with increased level of depression. Depression is associated with a reduction in the ability of people to effectively communicate in interpersonal settings. The interaction between end-stage renal disease patients and their physicians has important implications for the course of the treatment of this disease; however, there is limited research examining the influence of depression on general patient-physician communication. This study examines the association between depression and physician-patient communication in a sample of Hispanic end-stage renal disease patients. Participating patients filled out the Beck Depression Inventory and self-reported their feelings about meeting with physicians. Patients then met with a physician, and a nurse practitioner observed the interaction. Results indicate that depression was negatively associated with patients' self-reported perceptions of their readiness for the appointment (r =-.20) and with self-reported communication efficacy (r =-.19). Moreover, the nurse practitioner rated patients with depression as being significantly less likely (a) to ask for clarification (r =-.40), (b) to be engaged in the conversation (r =-.46), and (c) to be forthcoming with the physician (r =-.37). Results of this study have significant implications for communication between physicians and end-stage renal disease patients and for the influence of depression on patient-physician communication.

Quality of Internet education about living kidney donation for Hispanics

CONTEXT

Hispanics need disproportionately more kidney transplants, yet receive disproportionately fewer kidney transplants and living donor kidney transplants than non-Hispanic whites. Lack of knowledge and cultural beliefs about living kidney donation contribute to these disparities. The Internet is an optimal venue to educate underserved, low-literacy populations.

DESIGN

Websites were evaluated for information on living kidney donation targeted to Hispanics. Hispanic websites addressing living kidney donation were identified through the Google search engine, using the search terms Hispanic, Latino, Spanish, and living kidney donor/donation. Websites were evaluated for accessibility of information, readability, and content required by 9 Centers for Medicare and Medicaid Services regulations representing 12 topics, and cultural competency.

RESULTS

Twenty resources met inclusion criteria. Websites contained 2.3 pages on living kidney donation and required 2.4 links to access all information on living kidney donation. Websites were written at the 9th grade reading level. Sites described alternative treatments for recipients (n = 14), the evaluation process (n = 7), and the surgical procedure (n=6). Few addressed psychosocial risks (n=2). Some contained culturally sensitive colors and pictures (n = 8), but few addressed Hispanic cultural beliefs (n = 4).

CONCLUSIONS

A comprehensive website on living kidney donation that provides more robust content and is targeted to Hispanics is needed to increase Hispanics' understanding of treatment options.

Perceptions about organ donation among African American, Hispanic, and white high school students

We applied the Health Belief Model (HBM) to better understand perceptions of organ donation among African American, Hispanic, and White high school students. We conducted 14 focus groups with 18-year-old students to identify strategies to reach this audience when promoting the First-Person Consent Registry (FPCR) for organ donation. We found that African American, Hispanic, and White high school students are largely unaware of the need for organ donors, and are unfamiliar with how to join the FPCR. Participants identified more barriers to joining the FPCR than benefits. Two aspects of self-efficacy emerged related to joining the FPCR: decisional and task efficacy. Overall, few differences were found with respect to organ donation myths across the three ethnic groups. The results are discussed, with an emphasis on how the findings compare and contrast with previous organ donation research. We focus on message design and dissemination strategies for practitioners targeting 18-year-old high school students with organ donation promotional materials.

Family communication patterns moderate the relationship between psychological reactance and willingness to talk about organ donation

Considerable research has investigated how psychological reactance affects individuals' responses to health promotion messages, but little is known about how family processes might moderate the reactance process. In this study, 301 participants were exposed to a persuasive message about organ donation. The moderating role of family communication patterns in the reactance process was tested using hierarchical regression. We found that family conversation orientation had a direct effect on willingness to talk with family members about being an organ donor and that family conformity orientation and family conversation orientation each interacted with reactance to predict willingness to communicate with family about donation. Theoretically, these results extend psychological reactance theory by considering how interpersonal factors affect the reactance process. Practically, the findings suggest that for optimal impact, family processes should be considered in the design of messages promoting organ donation.

"Can you spare an organ?": exploring Hispanic Americans' willingness to discuss living organ donation with loved ones

Living organ donation offers a means of overcoming the shortage of viable organs available for transplant: a shortage particularly problematic among Hispanics. One barrier standing between those in need of a kidney and a successful transplant operation is an inability, and often lack of desire, to talk to loved ones about the need for a living donation. With an eye on future intervention approaches, and guided in part by the theory of planned behavior, this research effort sought to explore the factors associated with a willingness to engage in a conversation about a living donation with loved ones. Study 1, a phone survey of Hispanic Americans drawn from a Hispanic surname list, reveals that while upward of 90% of respondents would be willing to offer a kidney to a family member in need, and a similar percentage would be willing to accept a living donation if offered, only about half of respondents would feel comfortable initiating a conversation with family members if the respondent was in need of a living donation. Study 2, a survey of Hispanic American patients currently in need of a living kidney donation, revealed that perceived behavioral control accounted for 60% of the variance in future intentions to initiate a conversation among those who have yet to speak to a family member about becoming a living donor. Moreover, perceived behavioral control mediated the relationship between perceived asking appropriateness and future intentions to initiate a conversation. Lastly, recipient outcome expectations, asking appropriateness, and subjective norms were revealed to be predictive of perceived behavioral control. Implications for future living donor interventions focusing on increasing recipient-initiated conversations are discussed.

Patients' willingness to accept expanded criteria donor liver transplantation

Utilization of livers from expanded criteria donors (ECD) is one strategy to overcome the severe organ shortage. The decision to utilize an ECD liver is complex and fraught with uncertainty for both providers and patients. We assessed patients' willingness to accept ECD liver transplantation (LTx) and acceptable 1-year mortality risk. One hundred eight patients listed for LTx were asked to rate their willingness to accept ECD LTx and the associated 1-year mortality risk they were willing to accept. Also, patients completed the SF-36v2 and sociodemographic and health information was gathered from their medical records. Patients reported significantly higher willingness to accept standard criteria donor (SCD) versus ECD LTx (t = 13.8, p < 0.001), with more than one-third of patients reporting low willingness to accept ECD LTx. Relative to our center's 10% SCD LTx 1-year mortality rate, most patients (71%) were willing to accept moderately or substantially higher 1-year mortality risk for ECD LTx. In multivariable analyses, higher lab MELD score and white race were significant independent predictors of both ECD willingness and ECD increased mortality risk acceptability. Findings highlight the importance of assessing patients' willingness to pursue ECD LTx and the relative mortality risks they are willing to accept.

A close examination of trait reactance and issue involvement as moderators of psychological reactance theory

This study used psychological reactance theory (PRT) to investigate (a) the effectiveness of 2 message features (freedom-threatening language and character frame) and (b) the role of trait reactance and issue involvement as moderators of a perceived freedom threat. Within the context of organ donation, the results indicated no differences for character frame among the donor, recipient, or waiting list narratives. However, freedom-threatening language was positively associated with a perceived freedom threat. In turn, a perceived freedom threat was positively associated with state reactance, which was inversely, albeit nonsignificantly, associated with organ donation attitudes. Attitudes predicted intentions to be an organ donor. Results also revealed that trait reactance was positively associated with a perceived freedom threat. Although not associated with a freedom threat, issue involvement was positively associated with organ donation attitudes and intent to be a donor. Additionally, a trait reactance by issue involvement by freedom-threatening language interaction predicted a perceived freedom threat. Results are discussed with an emphasis on these moderators in PRT.

Are nonparticipants in prosocial behavior merely innocent bystanders?

Latané and Darley's (1970) bystander intervention theory was used to model individuals' participation in two prosocial behaviors (organ donation, green living). It is argued that nonparticipants in prosocial helping are innocent bystanders who likely fail to notice the need, do not interpret the cause as an emergency, do not accept responsibility for the need to help, and have little knowledge on how to help. Data in study 1 (n = 494) indicate support for the proposed innocent bystander path model (notice event → interpret event as emergency → accept responsibility → knowledge of how to help) in organ donation. Study 2 (n = 519) replicated the model in the context of green living and additionally found a direct path from noticing the event to knowledge of how to help. Implications of framing nonparticipation in prosocial behaviors as innocent bystander effects are discussed in context of campaign communication.

Transplant center provision of education and culturally and linguistically competent care: a national study

Although transplant centers are required to educate patients about kidney transplantation (KT) and living donation (LD), little is known about the educational format, and cultural and linguistic competence necessary for patients to make informed treatment decisions. This study surveyed US transplant administrators about education provided concerning KT and LD and culturally and linguistically competent care. Transplant administrators were invited to participate in an anonymous Internet-based survey about education format, education providers, promoting LD, culturally and linguistically competent care and center characteristics. Most (61%) transplant administrators contacted (N = 280/461) completed the survey. Most administrators (91%) reported that their center provides any type of formal education in their pre-KT evaluation. Education was mostly provided by: nurses (97%), social workers (72%) and surgeons (55%), and predominantly as one-on-one (80%) versus group discussions (60%). Education was primarily delivered through written materials (93%). Written educational materials in Spanish (86%) and the provision of interpreters (82%) were emphasized over educational sessions in Spanish (39%), or employing bilingual (51%) and bicultural staff (39%). Half (55%) promoted LD as the best option. Transplant centers need to take greater efforts to consistently provide appropriate education, promote LD, and provide culturally and linguistically competent care to ensure effective communication with all patients.

Addressing racial and ethnic disparities in live donor kidney transplantation: priorities for research and intervention

One potential mechanism for reducing racial/ethnic disparities in the receipt of kidney transplants is to enhance minorities' pursuit of living donor kidney transplantation (LDKT). Pursuit of LDKT is influenced by patients' personal values, their extended social networks, the health care system, and the community at large. This review discusses research and interventions promoting LDKT, especially for minorities, including improving education for patients, donors, and providers, using LDKT kidneys more efficiently, and reducing surgical and financial barriers to transplant. Future directions to increase awareness of LDKT for more racial/ethnic minorities also are discussed including developing culturally tailored transplant education, clarifying transplant-eligibility practice guidelines, strengthening partnerships between community kidney providers and transplant centers, and conducting general media campaigns and community outreach.

A mass mediated intervention on Hispanic live kidney donation

This research examines the impact of a Spanish language mass media campaign on living organ donation attitudes and behavioral intentions among Spanish dominant Hispanics in Tucson, Arizona. Impact was assessed via a pretest/posttest control group quasiexperimental design with Tucson, Arizona, as the intervention community and Phoenix, Arizona, as the control. Preintervention focus groups provided qualitative data to guide intervention development, while telephone surveys in both communities provided quantitative data to assess campaign impact. Analyses reveal pretest/posttest differences in the intervention community such that posttest intentions regarding living organ donation behaviors increased from pretest. No such differences were observed in the control community. Subsequent analyses revealed differences between respondents in the intervention community exposed to the campaign vs. those in the same community not exposed to the campaign. Exposed respondents reported more positive living organ donation behavioral intentions than nonexposed respondents. Implications for research and practice are discussed.

Attitudes, beliefs and behaviors surrounding organ donation among Hispanic women

PURPOSE OF REVIEW

Hispanic individuals are disproportionately in need of donor organs and are less likely to consent to donation than their non-Hispanic counterparts. This review addresses psychological constructs that include the attitudes and beliefs that surround organ donation within Hispanic communities and highlights the importance of women in the domain of organ donation.

RECENT FINDINGS

Attitudes toward living and posthumous donation are favorable. Mistrust of the medical profession, concerns about religious acceptance of donation, perceptions of inequity in the distribution of donated organs, and the context in which donation requests typically are made all serve as barriers to consent. Women are more likely to consent to donation than are men.

SUMMARY

Hispanic-American groups are heterogeneous. Culturally sensitive approaches to communicating a donation request must consider ethnic origin and language preference. Family discussion of donation should be encouraged by the medical community as part of healthcare decision-making (independent of death or crisis); women may serve as an excellent bridge between healthcare providers and families in this regard.

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.
