Impact of Cognitive Load on Family Decision Makers' Recall and Understanding of Donation Requests for the Genotype-Tissue Expression (GTEx) Project

Genomic research projects that collect tissues from deceased organ and tissue donors must obtain the authorization of family decision makers under difficult circumstances that may affect the authorization process. Using a quasi-experimental design, the Ethical, Legal, and Social Issues (ELSI) substudy of the Genotype-Tissue Expression (GTEx) project compared the recall and understanding of the donation authorization process of two groups: family members who had authorized donation of tissues to the GTEx project (the comparison group) and family members who had authorized organ and tissue donations in years previous, who subsequently participated in two different mock-authorization processes that mimicked the GTEx authorization process (the intervention groups). Participants in the comparison and intervention groups were matched on key demographic characteristics. We found that participants in the intervention groups who experienced a mock-authorization process demonstrated better recall of the tissue donation request than members of the comparison group. Our data indicate that the stress associated with the loss of a loved one limited the ability of family members to recall details about the GTEx project. However, we found a similar lack of knowledge in both the comparison and the intervention group participants, suggesting lack of knowledge may be due to the complexity and unfamiliarity of the information presented to them during the authorization process. We discuss these findings in the context of everyday clinical decision making in cognitively challenging conditions.

Hemodialysis Clinic Social Networks, Sex Differences, and Renal Transplantation

This study describes patient social networks within a new hemodialysis clinic and models the association between social network participation and kidney transplantation. Survey and observational data collected between August 2012 and February 2015 were used to observe the formation of a social network of 46 hemodialysis patients in a newly opened clinic. Thirty-two (70%) patients formed a social network, discussing health (59%) and transplantation (44%) with other patients. While transplant-eligible women participated in the network less often than men (56% vs. 90%, p = 0.02), women who participated discussed their health more often than men (90% vs. 45.5%, p = 0.02). Patients in the social network completed a median of two steps toward transplantation compared with a median of 0 for socially isolated patients (p = 0.003). Patients also completed more steps if network members were closely connected (β = 2.23, 95% confidence interval [CI] 0.16-4.29, p = 0.03) and if network members themselves completed more steps (β = 2.84, 95% CI 0.11-5.57, p = 0.04). The hemodialysis clinic patient social network had a net positive effect on completion of transplant steps, and patients who interacted with each other completed a similar number of steps.

Regional Differences in Communication Process and Outcomes of Requests for Solid Organ Donation

Although federal mandate prohibits the allocation of solid organs for transplantation based on "accidents of geography," geographic variation of transplantable organs is well documented. This study explores regional differences in communication in requests for organ donation. Administrative data from nine partnering organ procurement organizations and interview data from 1339 family decision makers (FDMs) were compared across eight geographically distinct US donor service areas (DSAs). Authorization for organ donation ranged from 60.4% to 98.1% across DSAs. FDMs from the three regions with the lowest authorization rates reported the lowest levels of satisfaction with the time spent discussing donation and with the request process, discussion of the least donation-related topics, the highest levels of pressure to donate, and the least comfort with the donation decision. Organ procurement organization region predicted authorization (odds ratios ranged from 8.14 to 0.24), as did time spent discussing donation (OR = 2.11), the number of donation-related topics discussed (OR = 1.14), and requesters' communication skill (OR = 1.14). Standardized training for organ donation request staff is needed to ensure the highest quality communication during requests, optimize rates of family authorization to donation in all regions, and increase the supply of organs available for transplantation.

A Comparison of Request Process and Outcomes in Donation After Cardiac Death and Donation After Brain Death: Results From a National Study

Available literature points to healthcare providers' discomfort with donation after cardiac death (DCD) and their perception of public reluctance toward the procedure. Using a national sample, we report on the communication content of actual DCD and donation after brain death (DBD) approaches by organ procurement organization (OPO) requesters and compare family decision makers' (FDMs') experiences of both modalities. We recruited 1601 FDMs using a validated protocol; 347 (21.7%) were of potential DCD donors. Semistructured telephone interviews yielded FDMs' sociodemographic data, donation attitudes, assessment of approach, final outcomes, and substantiating reasons. Initial analysis consisted of bivariate analyses. Multilevel mixture models compared groups representing authorization outcome and DCD/DBD status. No significant differences in family authorization were found between DCD and DBD cases. Statistically significant associations were found between sociodemographic characteristics and authorization, with white FDMs more likely to authorize DCD or DBD than black FDMs. FDMs of both modalities had similar evaluations of requester skills, topics discussed, satisfaction, and refusal reasons. The findings suggest that the DCD/DBD distinction may not be notable to families. We recommend the use of similar approach strategies and communication skills and the development of education campaigns about the public's acceptance of DCD.

Confidentiality in Biobanking Research: A Comparison of Donor and Nondonor Families' Understanding of Risks

AIMS

Confidentiality of personal identifiers potentially linking the genetic results from biobanking participants back to the donor and donor relatives is a concern. The risks associated with a breach of confidentiality should be ascertained when biobanks collect samples requiring the consent of a family decision maker (FDM) from deceased organ and tissue donors. This article explores FDM knowledge and opinions regarding risks associated with participation in biobanking research in the context of the Genotype-Tissue Expression (GTEx) Project.

METHODS

Data collection included a survey completed by organ procurement organization requesters (n = 37) and semistructured telephone interviews with the FDMs (n = 85).

RESULTS

Donor families were more likely to know that there was a risk that a patient's identity could be revealed through a breach of confidentiality (p < 0.05). They also were more likely to understand that researchers using biobanked tissue would not have access to the patient's exact identity (p < 0.05). FDMs who refused donation were more concerned about risks than donors and reported lower levels of support for medical research in general. Finally, families were frequently interested in the return of results and willing to trade absolute confidentiality for participation.

CONCLUSIONS

Clear discussion of the risk of breach of confidentiality is needed during the consent process. The risk and benefit equation could be equalized if studies such as GTEx offered genomic results to interested participants.

Communicating About Choices in Transplantation (COACH)

Introduction:

Previous research highlights the difficulties patients with end-stage renal disease awaiting kidney transplant experience while attempting to manage both the logistical and the content-related aspects of discussions about transplantation. This article presents pilot results of the behavioral communication intervention program, Communicating about Choices in Transplantation (COACH), designed to improve transplant candidates’ communication about transplantation.

Research Questions:

As compared to matched controls, increases in knowledge of deceased and living donor transplantation, communication self-efficacy, intentions to hold conversations about transplantation, and self-reported discussion were expected for pilot participants from pre- and postassessment; decreases in conversational difficulties were also posited.

Design:

Using a nonrandomized quasi-experimental design, we compared transplant knowledge and communication between patients completing a 2-hour COACH session (pilot sample) to a sample of matched controls (n = 10). Data were collected via semi-structured telephone interviews upon enrollment and 1 month after enrollment or attendance at a COACH program session.

Results:

The results revealed significant differences in knowledge from pre- to postassessment between the pilot and control samples ( P = .02). Although no other statistically significant between-group differences were found, paired-sample t tests revealed significant pre–post increases in transplant knowledge (7.6 [standard deviation, SD = 2.0] to 9.5 [SD =1.8]; P = .05) and communication self-efficacy (1255.8 [SD = 239.7] to 1513.8 [SD = 114.3]; P = .009) for pilot participants. Decreases in perceived conversational difficulties were also observed ( P = .53).

Discussion:

Results provide preliminary support for the program’s impact. Moreover, participant evaluations of the COACH were overwhelmingly positive. A more definitive program evaluation with a larger, more diverse sample is currently underway.

Living Kidney Donors' Information Needs and Preferences

INTRODUCTION

Past research suggests the information exchanged from transplant centers to potential living kidney donors is, in many cases, suboptimal. The purpose of this study was to assess donors' perceptions of the information provided while considering living donation.

METHODS

Semistructured telephone interviews conducted with 81 past living donors seen at 1 mid-Atlantic transplant center assessed the extent to which living kidney donors deemed Centers for Medicare and Medicaid Services (CMS)-mandated information useful to making a decision about donation and to which more information was or would have been desired before donating. Understanding of and satisfaction with the information was also assessed.

RESULTS

Participants were primarily white (67.9%), females (67.9%), with an average age of 57.8 years. Perceived usefulness ranged from a mean of 3.1 for the confidentiality of the transplant center's communication to 4.1 for postoperative care and short-term medical risks of donation. Donors of minority descent as well as those with more education and less income found the information provided most useful. Few donors desired additional information about the right to opt out of (8.6%) or decline (13.6%) donation; however, most wanted more information regarding the risk of being refused health, disability and/or life insurance after donating (77.8%), and insurance coverage for future health problems (66.7%).

DISCUSSION

This study revealed limited usefulness of certain CMS-mandated topics and a desire for additional information about donation. Efforts to standardize the informed consent process should incorporate donors' perspectives as to the specific topics, quantity of information, and the mode of communication found most useful when considering living donation.

Utility and Usability of the Rapid Assessment of Hospital Procurement Barriers in Donation (RAPiD) as a Tool for OPO Hospital Development Staff

CONTEXT

Few systematic assessment tools are available to organ procurement organizations (OPOs) for evaluating donation climates of hospitals in their donation service areas (DSAs). The Rapid Assessment of hospital Procurement barriers in Donation (RAPiD) was developed for OPO hospital development staff to assess the organ donation climate of hospitals.

OBJECTIVE

To implement a national test of the RAPiD to examine its efficacy and usability by OPO hospital development staff.

DESIGN

Two-arm randomized design, comparing implementation of RAPiD protocol between qualitatively trained researchers (n = 7) and OPO hospital development staff (n = 24); all evaluators received the same training assessments of high-yield hospitals.

SETTING

A total of 77 hospitals in DSAs of 8 OPOs.

PARTICIPANTS

A total of 2552 health-care providers (HCPs) in high organ donor potential units.

MAIN OUTCOME MEASURES

Twenty-four donation-related attitudes, knowledge, and behaviors.

RESULTS

More HCPs interviewed in the autonomous condition were positive toward the concept of organ donation. However, HCPs in the assisted condition were more candid about and critical of the OPO. As for knowledge, fewer HCPs in the autonomous condition reported familiarity with the donation process, need for donors, and generally accepted timely referral criteria. With respect to behaviors, more respondents in the autonomous condition reported frequent or occasional contact with the OPO and routine or occasional referral criteria use. Due to issues of bias, inadequate research experience, conflicts of interest, and ongoing OPO hospital development initiatives, the RAPiD's usability by OPO-based hospital development staff is questionable and not recommended in its current form. A next generation of the RAPiD is described for future consideration.

Keep it going: maintaining health conversations using relational and instrumental approaches

The initial moments of conversations, particularly discussions addressing difficult or unexpected health topics, establish the context and tone of the entire discussion. We examined how elements of relational and instrumental communication occurring within the first five minutes of the request impacted the length of the discussion. A sample of 16 U.S. tissue banking organizations and their staff (n = 226) making telephone requests for donation to families of tissue-donation eligible patients (n = 1,465) agreed to participate in the research. The first five minutes of 430 (29.4%) audiorecorded request conversations were qualitatively coded and analyzed. The primary outcome measure was whether the conversation continued beyond the first five minutes (yes/no). Aspects of both relational and instrumental communication were associated with discussion length. A logistic regression analysis found that the total number of distinct topics disclosed and requesters' vocal affect during the discussion as well as characteristics of the family member approached about donation predicted conversational maintenance. This research demonstrates that "thin slices" of effective relational and instrumental communication can have a significant, positive impact on conversation length.

Disparities in the completion of steps to kidney transplantation: protocol for a systematic review

INTRODUCTION

Disparities in access to transplantation have been well documented. The extant literature, however, focuses largely on disparities and related barriers for African-American patients and none has used the steps to transplantation as a guiding framework. This review will catalogue disparities in the steps to transplantation as well as the barriers and facilitators to completion of each step identified in the extant literature. The results of the review will be used to generate recommendations for future research to improve equity in access to kidney transplantation.

METHODS AND ANALYSIS

Standard procedures will be used in the conduct of the review. Searches will be performed using the following electronic databases: PubMed/Medline, PsycINFO, CINHAL, EMBASE, Cochrane library and Web of Science. Reports of original research will be eligible for inclusion if they are published from 2005 to present, written or available in English language, performed in the USA, enrol adult participants (18 years of age or more), and employ descriptive or observational designs. Two authors will independently screen retrieved articles for inclusion. MaxQDA will be used for data analysis and management. All included reports will be coded for article characteristics; disparities identified; barriers and motivators of completion of steps to transplantation; and proposed solutions to disparities and barriers. Each report will be coded independently by two authors and discrepancies resolved by discussion among the full team. A qualitative approach to data analysis is planned. Risk of bias will be assessed using standard procedures.

ETHICS AND DISSEMINATION

The findings will provide crucial information on the current status of disparities in access to transplantation. PRISMA guidelines will be followed in reporting the results of the review. It is anticipated that these results will inform research which seeks to increase parity in access to transplantation.

A Comparison of the Request Process and Outcomes in Adult and Pediatric Organ Donation

BACKGROUND AND OBJECTIVES

Although existing studies suggest that factors affecting families' decisions regarding pediatric organ donation mirror those for adult patients, health professionals working in this area maintain that pediatric and adult decision-makers differ in significant ways. This study compared the request process, experiences, and authorization decisions between family decision-makers (FDMs) of adult and pediatric donors and nondonors.

METHODS

Perceptions of the donation request were collected via telephone interviews with 1601 FDMs approached by staff from 9 US organ procurement organizations (OPOs). Authorization regarding donation (ie, authorized/refused) was obtained from FDM reports and verified by using OPO records. Tests of association were used to estimate differences between FDMs of adult and pediatric patients. A logistic regression analysis was conducted to identify variables predicting FDM authorization.

RESULTS

FDMs of children were significantly more likely to authorize donation than were FDMs of adults (89.7% vs 83.2%; χ(2) = 6.2, P = .01). Differences were found between pediatric and adult families' initial feelings toward donation, donation-related topics discussed, communication behaviors and techniques used, perceptions of the request, and receipt and preference of grief information. The likelihood of FDM authorization increased with the number of topics discussed and communication skills employed during requests. Authorization was not predicted by patient age (ie, adult versus pediatric).

CONCLUSIONS

FDMs of children are willing to donate and experience no more psychological distress from the request for donation than do FDMs of adults. Communication emerged as a critical factor of family authorization, reinforcing its importance in requests for donation.

Communication self-efficacy, perceived conversational difficulty, and renal patients' discussions about transplantation

OBJECTIVE

Many patients with chronic and end-stage renal disease (ESRD) have reported difficulties initiating and managing discussions about kidney transplantation, particularly live donor transplantation (LDT). Limited communication has demonstrable impact on patients' access to transplantation, the duration of dialysis treatments, and the length of time awaiting a transplantable kidney. This formative study sought to identify the specific communicative and conversational elements impeding ESRD patients' discussions about transplantation to inform the design of an educational program facilitating transplant-related discussions.

METHODS

From March to July 2012, semi-structured telephone interviews (n=63) were conducted with ESRD patients waitlisted for kidney transplantation at one mid-Atlantic transplant center.

RESULTS

Although 85.7% (n=54) of patients reported holding discussions about transplantation, qualitative analyses of open-ended responses revealed that the majority (66.7%) had limited conversations. Patients reported difficulties managing a variety of logistical and content-related aspects of LDT discussions. Moderate levels of communication self-efficacy were also found (mean=19.2 out of 28); self-efficacy was highest among respondents having held discussions and was significantly related to perceived magnitude of difficulty handling conversational aspects.

CONCLUSION

Results support comprehensive communication skills training for ESRD patients awaiting kidney transplantation.

PRACTICE IMPLICATIONS

Potential topics to be included in such training are discussed.

Consent to organ donation: a review

Successful transplant medicine hinges on consent to deceased organ donation. Yet rates of consent remain suboptimal. To increase the availability of transplantable organs, several policy strategies along with a rich body of evidence aimed at identifying best practices for obtaining consent have accumulated. This review describes past and current policies and practices, presents evidence illustrating the impact of these policies and practices on consent, and summarizes future directions and recommendations for the field. Key findings include evidence that although past policies such as required request have been unsuccessful, the recent policy, first-person authorization, shows promise. Additionally, practices such as decoupling and detailed discussions of brain death are unwarranted. On the other hand, the Organ Donation Breakthrough Collaboration was successful. We also underscore the impact of alternative procedures such as donation after cardiac death. Last, effective communication that is delivered by trained, caring requesters at the appropriate time, in a supportive environment, and allows sufficient time for families to make an informed decision, optimizes the request process. Organ procurement organizations' adoption of such request practices, implementation of evidence-based policies regarding donation after cardiac death, and further investigations of the medical basis for dual brain death examinations are recommended.

Interim results of a national test of the rapid assessment of hospital procurement barriers in donation (RAPiD)

Organ donation remains a major public health challenge with over 114 000 people on the waitlist in the United States. Among other factors, extant research highlights the need to improve the identification and timely referral of potential donors by hospital healthcare providers (HCPs) to organ procurement organizations (OPOs). We implemented a national test of the Rapid Assessment of hospital Procurement barriers in Donation (RAPiD) to identify assets and barriers to the organ donation and patient referral processes; assess hospital-OPO relationships and offer tailored recommendations for improving these processes. Having partnered with seven OPOs, data were collected at 70 hospitals with high donor potential in the form of direct observations and interviews with 2358 HCPs. We found that donation attitudes and knowledge among HCPs were high, but use of standard referral criteria was lacking. Significant differences were found in the donation-related attitudes, knowledge and behaviors of physicians and emergency department staff as compared to other staff in intensive care units with high organ donor potential. Also, while OPO staff were generally viewed positively, they were often perceived as outsiders rather than members of healthcare teams. Recommendations for improving the referral and donation processes are discussed.

Consenting to donation: an examination of current practices in informed consent for tissue donation in the US

Informed consent is the primary moral principle guiding the donation of human tissue for transplant purposes. When patients' donation wishes are not known, family members making the decision about tissue donation should be provided with requisite information needed to make informed donation decisions. Using a unique dataset of 1,016 audiotaped requests for tissue obtained from 15 US tissue banking organizations, we examined whether the information provided to families considering tissue donation met current standards for informed consent. The results indicated that many elements of informed consent were missing from the donation discussions, including the timeframe for procurement, autopsy issues, the involvement of both for-profit and nonprofit organizations, and the processing, storage and distribution of donated tissue. A multiple linear regression analysis also revealed that nonwhites and family members of increased age received less information regarding tissue donation than did younger, white decision makers. Recommendations for improving the practice of obtaining consent to tissue donation are provided.

An exploratory study of relational, persuasive, and nonverbal communication in requests for tissue donation

This study explores the effects of tissue requesters' relational, persuasive, and nonverbal communication on families' final donation decisions. One thousand sixteen (N = 1,016) requests for tissue donation were audiotaped and analyzed using the Siminoff Communication Content and Affect Program, a computer application specifically designed to code and assist with the quantitative analysis of communication data. This study supports the important role of communication strategies in health-related decision making. Families were more likely to consent to tissue donation when confirmational messages (e.g., messages that expressed validation or acceptance) or persuasive tactics such as credibility, altruism, or esteem were used during donation discussions. Consent was also more likely when family members exhibited nonverbal immediacy or disclosed private information about themselves or the patient. The results of a hierarchical log-linear regression revealed that the use of relational communication during requests directly predicted family consent. The results provide information about surrogate decision making in end-of-life situations and may be used to guide future practice in obtaining family consent to tissue donation.

Improving Donation Outcomes: Hospital Development and the Rapid Assessment of Hospital Procurement Barriers in Donation

Context

Deficiencies in the donation process continue to contribute to the shortage of organs available for transplant. Continuous quality improvement of hospitals' donation processes is needed to identify and correct the problems.

Objective

To test the Rapid Assessment of Hospital Procurement Barriers in Donation (RAPiD), a direct observation technique with a focused ethnographic strategy, for assessing hospitals' donation processes and identifying areas in need of continuous quality improvement interventions.

Design

A pre-post assessment of hospitals' barriers to patient identification and referral, and family consent to donation.

Setting and Participants

Seventeen hospitals within the catchment area of a Northeastern organ procurement organization were assessed by using the RAPiD method. Hospital administrators, health care providers, and staff (N = 537) were interviewed as part of the assessments.

Intervention

Interventions, including on-site training and education, and the use of in-house coordinators, were specifically tailored to each hospital's unique set of barriers to donation. The interventions were delivered to the hospitals in the form of recommendations. The participating organ procurement organization was responsible for implementation of the interventions.

Results

The RAPiD hospital evaluations revealed gaps in respondents' knowledge of organ donation, brain death, and referral criteria; a reluctance to declare brain death; and a rocky relationship between the hospitals and the organ procurement organization. As a result of the interventions, 9 hospitals' environments for organ donation improved, 7 showed no change, and 1 was worse.
