Organ Donation Breakthrough Collaborative

Victory out of tragedy: organ donation

Major improvements in trauma care during the last decade have improved survival rates in the severely injured. The unintended consequence is the presentation of patients with non-survivable injuries in a time frame in which intervention is considered and often employed due to prognostic uncertainty. In light of this, discerning survivability in these patients remains increasingly problematic. Evidence-based cut-points of futility can guide early decisions for discontinuing aggressive treatment and use of precious resources in severely injured patients arriving in extremis.

The impact of donor consent mechanism on organ procurement organization performance in the United States

BACKGROUND

Lack of donor organ availability represents a major limitation to the success of solid organ transplantation. The Scientific Registry of Transplant Recipients (SRTR) publishes performance reports of organ procurement organizations (OPO) in the United States, but does not stratify by the mechanism of donor consent, namely first-person authorization (organ donor registry) and next-of-kin authorization. This study aimed to report the trends in deceased organ donation in the United States and assess the regional differences in OPO performance after accounting for the different mechanisms of donor consent.

METHODS

The SRTR database was queried for all eligible deaths (2008-2019) which were then stratified based on the mechanism of donor authorization. Multivariable logistic regression was performed to assess the probability of organ donation across OPOs based on specific donor consent mechanisms. Eligible deaths were divided into 3 cohorts based on the probability to donate. Consent rates at the OPO level were calculated for each cohort.

RESULTS

Organ donor registration among adult eligible deaths in the U.S. increased over time (2008: 10% vs 2019: 39%, p < 0.001), coincident with a decline in next-of-kin authorization rates (2008: 70% vs 2019: 64%, p < 0.001). At the OPO level, the increased organ donor registration was associated with lower next-of-kin authorization rates. Among eligible deaths with medium- and low-probability of donation, recruitment was highly variable across OPO's, ranging from 36% to 75% in the medium-probability group (median 54%, IQR 50%-59%) and 8% and 73% in the low-probability group (median 30%, IQR 17%-38%).

CONCLUSION

Significant variability exists across OPOs in the consent of potentially persuadable donors after adjusting for population demographic differences and the mechanism of consent. Current metrics may not truly reflect OPO performance as they do not account for consent mechanism. There is further opportunity for improvement in deceased organ donation through targeted initiatives across OPOs, modeled after regions with the best performance.

Understanding organ donation processes and structures in ontario: A social network analysis approach

BACKGROUND

Transplant rates in Ontario rose steeply in the decade prior to the COVID-19 pandemic. Reasons for that increase remain unclear, but the inter-organizational arrangement of organ donation programs may have contributed. However, there is a paucity of literature investigating these inter-organizational arrangements, with a limited understanding of how communication facilitates organ donation. Understanding these arrangements may help to re-establish rising organ donation rates post-pandemic.

OBJECTIVE

To describe interprofessional interactions of Organ and Tissue Donation Coordinators (OTDCs) during organ donation cases, within organ donation programs in Ontario, from an organizational perspective (describing structure, context, process).

METHODS

Mixed-method social network analysis (SNA) approach analyzing 14 organ donation cases just before the COVID-19 pandemic.

RESULTS

Structure: Social network graphs depict the joint work performed by hospital staff and OTDCs, with a great part of the communication being processed through the OTDC.

CONTEXT

Network density ranged from 0.05 to 0.24 across cases, and health care professionals perceived an atmosphere of shared vision and trust among team members.

PROCESS

Most networks had a degree centralization <0.50 suggesting a decentralized information flow, and participants perceived decisions being jointly made. The characteristic path length of cases ranged from 1.6 to 3.2, suggesting potential for rapid information diffusion. Overall, data reinforced the OTDC role of intermediator within the communication process, and hospital staff perceived OTDCs as central players. Hospital staff and OTDCs reported frustration with some aspects of the flow of information during the organ allocation processes.

CONCLUSION

Findings from this study provide a network map of communications within organ donation cases and reinforce the importance of the OTDC role. Opportunities for quality improvement within these processes are identified.

Predictors of Deceased Organ Donation in the Pediatric Population

BACKGROUND

A shortage of donor organs represents the major barrier to the success of solid organ transplantation. This is especially true in the pediatric population for which the number of organ donors has decreased over time. With this study, we aimed to assess the factors associated with deceased organ donor consent in the pediatric population and determine the variability in consent rates across organ procurement organizations (OPOs).

METHODS

All eligible pediatric deaths were identified from the Scientific Registry of Transplant Recipients (2008-2019). The rate of organ donor consent was determined, and multivariable logistic regression was used to assess the factors independently associated with successful donor recruitment. The probability of donor consent was determined for each OPO after adjusting for patient demographics.

RESULTS

A total of 11 829 eligible pediatric deaths were approached to request consent for organ donation. Consent was successful in 8816 (74.5%) subjects. Consent rates are lower in the pediatric population compared with young adults and are directly related to patient age such that eligible infant deaths have the lowest rate of successful donor consent. There is significant variability in donor consent rates across OPOs, independent of population demographic differences.

CONCLUSIONS

OPO is predictive of pediatric deceased organ donor consent independent of demographic differences, with some regions having consistently higher consent rates than others. Sharing best practices for pediatric deceased donor recruitment may be a strategy to increase organ availability in the pediatric population.

Defining Quality Criteria for Success in Organ Donation Programs: A Scoping Review

Background

Well-established performance measures for organ donation programs do not fully address the complexity and multifactorial nature of organ donation programs such as the influence of relationships and organizational attributes.

Objective

To synthesize the current evidence on key organizational attributes and processes of international organ donation programs associated with successful outcomes and to generate a framework to categorize those attributes.

Design

Scoping Review using a mixed methods approach for data extraction.

Setting

Databases included PubMed, CINAHL, Embase, LILACS, ABI Business ProQuest, Business Source Premier, and gray literature (organ donation association websites, Google Scholar-first 8 pages), and searches for gray literature were performed, and relevant websites were perused.

Sample

Organ donation programs or processes.

Methods

We systematically searched the literature to identify any research design, including text and opinion papers and unpublished material (research data, reports, institutional protocols, government documents, etc). Searches were completed on January 2018, updated it in May 2019, and lastly in March 2020. Title, abstracts, and full texts were screened independently by 2 reviewers with disagreements resolved by a third. Data extraction followed a mixed method approach in which we extracted specific details about study characteristics such as type of research, year of publication, origin/country of study, type of journal published, and key findings. Studies included considered definitions and descriptions of success in organ donation programs in any country by considering studies that described (1) attributes associated with success or effectiveness, (2) organ donation processes, (3) quality improvement initiatives, (4) definitions of organ donation program effectiveness, (5) evidence-based practices in organ donation, and (6) improvements or success in such programs. We tabulated the type and frequency of the presence or absence of reported improvement quality indicators and used a qualitative thematic analysis approach to synthesize results.

Results

A total of 84 articles were included. Quantitative analysis identified that most of the included articles originated from the United States (n = 32, 38%), used quantitative approaches (n = 46, 55%), and were published in transplant journals (n = 34, 40.5%). Qualitative analysis revealed 16 categories that were described as positively influencing success/effectiveness of organ donation programs. Our thematic analysis identified 16 attributes across the 84 articles, which were grouped into 3 categories influencing organ donation programs' success: context (n = 39, 46%), process (n = 48, 57%), and structural (n = 59, 70%).

Limitations

Consistent with scoping review methodology, the methodological quality of included studies was not assessed.

Conclusions

This scoping review identified a number of factors that led to successful outcomes. However, those factors were rarely studied in combination representing a gap in the literature. Therefore, we suggest the development and reporting of primary research investigating and measuring those attributes associated with the performance of organ donation programs holistically.

Effect of a multidisciplinary program to improve organ donation in the emergency department

BACKGROUND AND IMPORTANCE

As the emergency department (ED) is an important source of potential organ donors, it may play an important role in the organ donation process.

OBJECTIVE

To assess the effectiveness of the multidisciplinary organ donation improvement program (ODIP) on identifying potential donors and improving organ donation in South Korean EDs.

DESIGN, SETTINGS, AND PARTICIPANTS

This study was a retrospective, observational study of the ED-inclusive ODIP implemented in 55 tertiary teaching hospitals contracted with the Korea Organ Donation Agency (KODA) since 2014. The inclusion criteria were: patients in the ED with a serious brain injury and futile prognosis or expected death of the patient within a few days, no contraindications for organ donation, and no objections registered in the donor registry.

INTERVENTION

The ED-inclusive multidisciplinary approach was implemented to improve organ donation. It included regular meetings of the ODIP committee, hospital visits and staff education, improvement of notifications, and support of a coordination team.

OUTCOMES MEASURE AND ANALYSIS

We assessed the changes in the number of deceased organ donors per year and notifications of potential brain-dead donors by medical staff after the implementation of the new ED-inclusive ODIP. The entire organ donation process was monitored and measured.

RESULTS

There was a significant increase in deceased organ donors per million population after the implementation of the ED-inclusive multidisciplinary ODIP of KODA compared to the pre-intervention period: 5.21 vs. 9.72, difference 4.51 (95% confidence interval 2.11-6.91). During the study period, the proportion of deceased organ donors occurred from KODA-contracted hospitals increased from 25.3 to 50.3% in South Korea's total deceased organ donors. Emergency physicians of KODA-contracted hospitals notified increasingly more potential brain-dead donors each year throughout the study period (36 in 2014 vs. 135 in 2018). The longer the period contracted with KODA, the higher the potential brain-death identification rates (P < 0.001).

CONCLUSION

In this retrospective study, the implementation of multidisciplinary ODIP in the ED led to significantly higher deceased organ donors per million population and awareness of potential brain-dead donors in South Korea.

There are no best practices in a pandemic: Organ donation within the COVID-19 epicenter

LiveOnNY, the organ procurement organization (OPO) for the greater New York metropolitan area, suspended several best practices to manage the rising referrals of deaths from hospitals during the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pandemic. On April 2, 2020 hospitals in the donor service area were notified that coronavirus disease 2019 (COVID-19) referrals should be deferred. Still, only 2% of referred patients to the OPO in April 2020 were on ventilators and considered possible organ donors, versus a baseline of 11% in 2019. Few of these deaths were unrelated to COVID-19. Accordingly, organ donors declined to 10 in April (from 26 in March). Despite the exclusion of marginal donors and organs, the implementation of COVID-19 donor testing, and the availability of local procurement surgeons, only 1 organ (a liver) was accepted by a transplant center outside of New York State and 8 organs (5 livers, 4 kidneys) were transplanted in state; 11 organs (1 liver, 10 kidneys) were discarded. Allocation was unsuccessful for 11 additional organs (1 liver, 4 kidneys, 4 hearts, 2 lungs). Despite the obstacles, organ donation remained an important model of collaboration and satisfaction for the health care community in the pandemic's US epicenter. Declining COVID-19 deaths led to the resumption of the comprehensive referral policy on May 6, 2020, with improvement to 18 donors in May.

Grief, Stress, Trauma, and Support During the Organ Donation Process

The organ donation process is complex and stressful for the family of the potential donor and members of the multidisciplinary team who may experience grief, ethical dilemmas, vicarious trauma, or compassion fatigue. Several studies each explore the role of a specific healthcare group and the impact of inhospital processes on group members. We conducted a systematic literature search to identify such studies and a qualitative synthesis to consolidate findings and highlight features of the interaction and relationships between role players. Our results suggest that, while healthcare professionals have different roles, attitudes, and views, the experience of stressors and interdisciplinary tension is common. Nevertheless, staff are united by the goal of caring for the patient and family. We therefore propose that, while focusing on bereavement care and other aspects of the family's experience, staff can find other shared goals and develop understanding, trust, empathy, and respect for each other's positions, thereby improving functioning in the complex adaptive system that forms at this time. Education and training can equip staff to facilitate anticipatory mourning, family-led activities, and a meaningful parting from their relative, assisting families with their grief and increasing staff members' efficacy, confidence, and interdisciplinary teamwork. Knowledge of systems thinking and opportunities to share ideas and experiences will enable staff to appreciate each other's roles, while supportive mentors, self-care strategies, and meaningful feedback between role players will foster healthy adjustment and shared learning. A focus on psychosocial outcomes such as family satisfaction with the process, collaboration within the multidisciplinary team, and reduction in the role stress of healthcare professionals will contribute to family well-being as well as personal and professional growth for staff.

How Inaccurate Metrics Hide the True Potential for Organ Donation in the United States

BACKGROUND

There is a discrepancy between the reported increase in donor conversion rates and the number of organs available for transplant.

METHODS

Secondary analysis of data obtained from the Scientific Registry of Transplant Recipients from January 2003 through December 2015 was performed. The primary outcomes were the (1) number of brain-dead donors from whom solid organs were recovered and (2) number of the organs transplanted. Descriptive statistics and growth plots were used to examine the trajectory of organ donation, recovery, and transplantation outcomes over the 11-year period.

RESULTS

From 2003 to 2006, the number of brain-dead donors increased from 6187 to 7375, remaining relatively stable at approximately 7200 thereafter. The average eligible deaths per organ procurement organization dropped from 182.7 (standard deviation [SD]: 131.3) in 2003 to 149.3 (SD: 111.4) in 2015. This suggests a total of 12 493 unrealized potential donors (2006-2015).

CONCLUSIONS

Since 2006, a steady decline in the number of donor-eligible deaths was reported. In 2003, the reported eligible deaths was 11 326. This number peaked in 2004 at 11 346, tumbling to 9781 eligible donors in 2015, despite a 9% increase in the US population. From 2006 to 2015, the data indicate an artificial depression and underestimation of the true potential of brain-dead donors in the United States of conservatively 12 493 donors or 39 728 missing organs. New metrics providing objective but verifiable counts of the donor pool are needed.

Estimated Association Between Organ Availability and Presumed Consent in Solid Organ Transplant

IMPORTANCE

Presumed consent, or an opt-out organ transplant policy, has been adopted by many countries worldwide to increase organ donation. The implication of such a policy for transplants in the United States is uncertain, however.

OBJECTIVE

To simulate the potential implications of a presumed consent policy in the United States.

DESIGN, SETTING, AND PARTICIPANTS

In a decision analytical model, a simulation model was developed using cohort data from January 1, 2004, to December 31, 2014, in the Organ Procurement and Transplantation Network Standard Transplant Analysis and Research files. All US patients (n = 524 359) who were on the waiting list for at least 1 solid organ and all deceased organ donors during the study period were included in the analyses. All data and statistical analyses were performed from January 30, 2019, to July 31, 2019.

MAIN OUTCOMES AND MEASURES

Increase in the organs available for donation and life-years gained associated with a 5%, 15%, or 25% increase in deceased donors, based on the published changes from a presumed consent policy.

RESULTS

This study considered 524 359 unique candidates (aged ≥18 years; 320 908 [61.2%] male) for a solid organ transplant from January 1, 2004, to December 31, 2014. With a base case scenario of a 5% presumed consent-associated increase in donors, the removals (owing to death or illness) from the waiting list for all organs would have an associated 3.2% to 10.4% mean reduction, depending on the random or ideal allocation of new organs to patients on the waiting list. Sensitivity analyses showed that waiting list removals could be decreased up to 52%; however, this reduction was not enough to completely eliminate waiting list removals during the study period. The biggest estimated increases in annual life-years gained associated with a presumed consent policy were in kidney transplant candidates (95% CIs by deceased donor increase: 5% increase, 3440-3466 years; 15% increase, 10 321-10 399 years; 25% increase, 17 201-17 332 years) and liver transplant candidates (95% CIs by deceased donor increase: 5% increase, 898-905 years; 15% increase, 2693-2714 years; 25% increase, 4448-4523 years). Adoption of a presumed consent policy could result in a 4295-year (95% CI, 4277-4313 years) to 11 387-year (95% CI, 11 339-11 435 years) increase in life-years, accounting for the survival advantages associated with a transplant.

CONCLUSIONS AND RELEVANCE

In this study, presumed consent was estimated to be associated with modest but important improvement in the number of organ transplants and increases in life-years gained for patients awaiting an organ transplant. Further consideration and even debate about the ethical and public policy implications of a presumed consent policy are warranted.

Patterns of geographic variability in mortality and eligible deaths between organ procurement organizations

Eligible deaths are currently used as the denominator of the donor conversion ratio to mitigate the effect of varying mortality patterns in the populations served by different organ procurement organizations (OPOs). Eligible death is an OPO-reported metric rather than a product of formal epidemiological analysis, however, and may be confounded with OPO performance. Using Scientific Registry of Transplant Recipients and Centers for Disease Control and Prevention data, patterns of mortality and eligible deaths within each OPO were analyzed with the use of formal geostatistical analysis to determine whether eligible deaths truly reflect the geographic patterns they are intended to mitigate. There was a 2.1-fold difference in mortality between the OPOs with the highest and lowest rates, with significant positive spatial autocorrelation evident in mortality rates (Moran I = .110; P < .001), meaning geographically proximate OPOs tended to have similar mortality rates. The eligible death ratio demonstrated greater variability, with a 4.5-fold difference between the OPOs with the highest and lowest rates. Contrary to the pattern of mortality rates, the geographic distribution of eligible deaths among OPOs was random (Moran I = -.002; P = .410). This finding suggests geographic patterns do not play a significant role in eligible deaths, thus questioning its continuing use in OPO performance comparisons.

Evolution of Deceased Organ Donation Activity Versus Efficiency Over a 15-year Period: An International Comparison

BACKGROUND

The donation rate (DR) per million population is not ideal for an efficiency comparison of national deceased organ donation programs. The DR does not account for variabilities in the potential for deceased donation which mainly depends on fatalities from causes leading to brain death. In this study, the donation activity was put into relation to the mortality from selected causes. Based on that metric, this study assesses the efficiency of different donation programs.

METHODS

This is a retrospective analysis of 2001 to 2015 deceased organ donation and mortality registry data. Included are 27 Council of Europe countries, as well as the United States. A donor conversion index (DCI) was calculated for assessing donation program efficiency over time and in international comparisons.

RESULTS

According to the DCI and of the countries included in the study, Spain, France, and the United States had the most efficient donation programs in 2015. Even though mortality from the selected causes decreased in most countries during the study period, differences in international comparisons persist. This indicates that the potential for deceased organ donation and its conversion into actual donation is far from being similar internationally.

CONCLUSIONS

Compared with the DR, the DCI takes into account the potential for deceased organ donation, and therefore is a more accurate metric of performance. National donation programs could optimize performance by identifying the areas where most potential is lost, and by implementing measures to tackle these issues.

Agents of change: establishing quality improvement collaboratives to improve adherence to Australian clinical guidelines for dementia care

BACKGROUND

Dissemination of clinical practice guidelines alone is insufficient to create meaningful change in clinical practice. Quality improvement collaborative models have potential to address the evidence-practice gap in dementia care because they capitalise on known knowledge translation enablers and incorporate optimal approaches to implementation. Non-pharmacological interventions focused on promoting independence are effective and favoured by people with dementia and their carers but are not routinely implemented. The objective of this translational project is to assess the impact of quality improvement collaboratives (QICs) on adherence to non-pharmacological recommendations from the Clinical Practice Guidelines for Dementia in Australia.

METHODS

This project will employ an interrupted time-series design with process evaluation to assess the impact, uptake, feasibility, accessibility, cost, and sustainability of the QICs over 18 months. Thirty clinicians from across Australia will be invited to join the QICs to build their capacity in leading innovation in dementia care. Clinicians will participate in a training program and be supported to develop and implement a quality improvement project unique to their service context using plan-do-study-act cycles. Regular online meetings with their peers in the QIC will facilitate benchmarking and problem-solving. Clinicians will describe their practice via monthly checklists, and guideline adherence will be determined against a set of defined criteria. Phone interviews with up to 180 client dyads will be used to assess satisfaction with care and client outcomes. Clinician interviews and field note data will be used to explore implementation and costs. Involvement of people with dementia and carers will be embedded in the study design, conduct, and reporting, in addition to clinical and industry expertise.

DISCUSSION

The quality of dementia care in Australia is largely dependent on the clinician involved and the extent to which they apply best available evidence in their practice. This study will determine the elements of this multifaceted implementation strategy that contributed to guideline adherence and client outcomes. The findings will inform future translational approaches to improving care and outcomes for people with dementia and their carers.

PROviding Better ACcess To ORgans: A comprehensive overview of organ-access initiatives from the ASTS PROACTOR Task Force

The American Society of Transplant Surgeons (ASTS) PROviding better Access To Organs (PROACTOR) Task Force was created to inform ongoing ASTS organ access efforts. Task force members were charged with comprehensively cataloguing current organ access activities and organizing them according to stakeholder type. This white paper summarizes the task force findings and makes recommendations for future ASTS organ access initiatives.

Improved waitlist and transplant outcomes for pediatric lung transplantation after implementation of the lung allocation score

BACKGROUND

Although the lung allocation score (LAS) has not been considered valid for lung allocation to children, several additional policy changes for pediatric lung allocation have been adopted since its implementation. We compared changes in waitlist and transplant outcomes for pediatric and adult lung transplant candidates since LAS implementation.

METHODS

The United Network for Organ Sharing database was reviewed for all lung transplant listings during the period 1995 to June 2014. Outcomes were analyzed based on date of listing (pre-LAS vs post-LAS) and candidate age at listing (adults >18 years, adolescents 12 to 17 years, children 0 to 11 years).

RESULTS

Of the 39,962 total listings, 2,096 (5%) were for pediatric candidates. Median waiting time decreased after LAS implementation for all age groups (adults: 379 vs 83 days; adolescents: 414 vs 104 days; children: 211 vs 109 days; p < 0.001). The proportion of candidates reaching transplant increased after LAS (adults: 52.6% vs 71.6%, p < 0.001; adolescents: 40.3% vs 61.6%, p < 0.001; children: 42.4% vs 50.9%, p = 0.014), whereas deaths on the waitlist decreased (adults: 28.0% vs 14.4%, p < 0.001; adolescents: 33.1% vs 20.9%, p < 0.001; children: 32.2% vs 25.0%; p = 0.025), despite more critically ill candidates in all groups. Median recipient survival increased after LAS for adults and children (adults: 5.1 vs 5.5 years, p < 0.001; children: 6.5 vs 7.6 years, p = 0.047), but not for adolescents (3.6 vs 4.3 years, p = 0.295).

CONCLUSIONS

Improvements in waiting time, mortality and post-transplant survival have occurred in children after LAS implementation. Continued refinement of urgency-based allocation to children and broader sharing of pediatric donor lungs may help to maximize these benefits.

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.

Organ donation education initiatives: A report of the Donor Management Task Force

PURPOSE

It is essential that hospitals and health professionals establish systems to facilitate patients' organ donation wishes. Donation education has been neither standardized nor systematic, and resources related to donation processes have not been widely accessible. This report describes 2 free, publicly available educational resources about the organ donation process created to advance the mission of basic education and improve donation processes within hospitals and health care systems.

MATERIALS AND METHODS

Members of the Donor Management Task Force of the Organ Donation and Transplantation Alliance (the Alliance) and the Health Resources and Services Administration of the US Department of Health and Human Services convened annually in person and by teleconferencing during the year to develop 2 educational vehicles on organ donation.

RESULTS

Two educational products were developed: the Organ Donation Toolbox, an online repository of documents and resources covering all aspects of the donation process, and the Educational Training Video that reviews the basic foundations of a successful hospital donation system.

CONCLUSIONS

There is a need for more research and education about the process of organ donation as it relates to the medical and psychosocial care of patients and families before the end of life. The educational products described can help fill this critical need.

Pediatric Deceased Donation-A Report of the Transplantation Society Meeting in Geneva

The Ethics Committee of The Transplantation Society convened a meeting on pediatric deceased donation of organs in Geneva, Switzerland, on March 21 to 22, 2014. Thirty-four participants from Africa, Asia, the Middle East, Oceania, Europe, and North and South America explored the practical and ethical issues pertaining to pediatric deceased donation and developed recommendations for policy and practice. Their expertise was inclusive of pediatric intensive care, internal medicine, and surgery, nursing, ethics, organ donation and procurement, psychology, law, and sociology. The report of the meeting advocates the routine provision of opportunities for deceased donation by pediatric patients and conveys an international call for the development of evidence-based resources needed to inform provision of best practice care in deceased donation for neonates and children.

Neonatal and Pediatric Organ Donation: Ethical Perspectives and Implications for Policy

The lifesaving processes of organ donation and transplantation in neonatology and pediatrics carry important ethical considerations. The medical community must balance the principles of autonomy, non-maleficence, beneficence, and justice to ensure the best interest of the potential donor and to provide equitable benefit to society. Accordingly, the US Organ Procurement and Transplantation Network (OPTN) has established procedures for the ethical allocation of organs depending on several donor-specific and recipient-specific factors. To maximize the availability of transplantable organs and opportunities for dying patients and families to donate, the US government has mandated that hospitals refer potential donors in a timely manner. Expedient investigation and diagnosis of brain death where applicable are also crucial, especially in neonates. Empowering trained individuals from organ procurement organizations to discuss organ donation with families has also increased rates of consent. Other efforts to increase organ supply include recovery from donors who die by circulatory criteria (DCDD) in addition to donation after brain death (DBD), and from neonates born with immediately lethal conditions such as anencephaly. Ethical considerations in DCDD compared to DBD include a potential conflict of interest between the dying patient and others who may benefit from the organs, and the precision of the declaration of death of the donor. Most clinicians and ethicists believe in the appropriateness of the Dead Donor Rule, which states that vital organs should only be recovered from people who have died. The medical community can maximize the interests of organ donors and recipients by observing the Dead Donor Rule and acknowledging the ethical considerations in organ donation.

Increasing the Number of Organ Transplants in the United States by Optimizing Donor Authorization Rates

While recent policies have focused on allocating organs to patients most in need and lessening geographic disparities, the only mechanism to increase the actual number of transplants is to maximize the potential organ supply. We conducted a retrospective cohort study using OPTN data on all "eligible deaths" from 1/1/08 to 11/1/13 to evaluate variability in donor service area (DSA)-level donor authorization rates, and to quantify the potential gains associated with increasing authorization rates. Despite adjustments for donor demographics (age, race/ethnicity, cause of death) and geographic factors (rural/urban status of donor hospital, statewide participation in deceased-donor registries) among 52 571 eligible deaths, there was significant variability (p < 0.001) in donor authorization rates across the 58 DSAs. Overall DSA-level adjusted authorization rates ranged from 63.5% to 89.5% (median: 72.7%). An additional 773-1623 eligible deaths could have been authorized, yielding 2679-5710 total organs, if the DSAs with authorization rates below the median and 75th percentile, respectively, implemented interventions to perform at the level of the corresponding reference DSA. Opportunities exist within the current organ acquisition framework to markedly improve DSA-level donor authorization rates. Such initiatives would mitigate waitlist mortality while increasing the number of transplants.

Declining liver graft quality threatens the future of liver transplantation in the United States

National liver transplantation (LT) volume has declined since 2006, in part because of worsening donor organ quality. Trends that degrade organ quality are expected to continue over the next 2 decades. We used the United Network for Organ Sharing (UNOS) database to inform a 20-year discrete event simulation estimating LT volume from 2010 to 2030. Data to inform the model were obtained from deceased organ donors between 2000 and 2009. If donor liver utilization practices remain constant, utilization will fall from 78% to 44% by 2030, resulting in 2230 fewer LTs. If transplant centers increase their risk tolerance for marginal grafts, utilization would decrease to 48%. The institution of "opt-out" organ donation policies to increase the donor pool would still result in 1380 to 1866 fewer transplants. Ex vivo perfusion techniques that increase the use of marginal donor livers may stabilize LT volume. Otherwise, the number of LTs in the United States will decrease substantially over the next 15 years. In conclusion, the transplant community will need to accept inferior grafts and potentially worse posttransplant outcomes and/or develop new strategies for increasing organ donation and utilization in order to maintain the number of LTs at the current level.

Views of health care personnel on organ donation and transplantation: A literature review

The purpose of this study was to review the empirical studies on health personnel's views towards organ donation and transplantation. A scoping review was carried out in English, Portuguese and Spanish. The search was conducted in eight databases, and two search engines. Four groups of descriptors were used. The period covered was 1985 to 2013. Frequency and content analysis was performed. Two hundred forty-eight articles were selected, out of 316 identified. The literature is temporally and geographically clustered. Quantitative studies predominate. The studies prioritized the perspective of medical and nursing personnel over other actors, such as directors and organ donation coordinators. Health personnel's attitudes toward deceased organ donation was the most examined topic. In conclusion, a growing quantitative literature analyzes the perspective of physicians and nurses with regard to deceased organ donation and transplantation.

Breakdown in the organ donation process and its effect on organ availability

Background. This study examines the effect of breakdown in the organ donation process on the availability of transplantable organs. A process breakdown is defined as a deviation from the organ donation protocol that may jeopardize organ recovery. Methods. A retrospective analysis of donation-eligible decedents was conducted using data from an independent organ procurement organization. Adjusted effect of process breakdown on organs transplanted from an eligible decedent was examined using multivariable zero-inflated Poisson regression. Results. An eligible decedent is four times more likely to become an organ donor when there is no process breakdown (adjusted OR: 4.01; 95% CI: 1.6838, 9.6414; P < 0.01) even after controlling for the decedent's age, gender, race, and whether or not a decedent had joined the state donor registry. However once the eligible decedent becomes a donor, whether or not there was a process breakdown does not affect the number of transplantable organs yielded. Overall, for every process breakdown occurring in the care of an eligible decedent, one less organ is available for transplant. Decedent's age is a strong predictor of likelihood of donation and the number of organs transplanted from a donor. Conclusion. Eliminating breakdowns in the donation process can potentially increase the number of organs available for transplant but some organs will still be lost.

National decline in donor heart utilization with regional variability: 1995-2010

The severe shortage of donor hearts limits the availability of transplantation for the growing population of patients with end-stage heart disease. We examined national trends in donor heart acceptance for transplant. OPTN data were analyzed for all potential adult cardiac organ donors between 1995 and 2010. Donor heart disposition was categorized as transplanted, declined for transplant or other. We studied changes in the probability of donor heart acceptance according to demographic and clinical characteristics, nationwide and by UNOS region. Of 82 053 potential donor hearts, 34% were accepted and 48% were declined (18% used for other purposes). There was a significant decrease in donor heart acceptance from 44% in 1995 to 29% in 2006, and subsequent increase to 32% in 2010. Older donor age, female sex and medical co-morbidities predicted non-acceptance. Donor age and co-morbidities increased during the study period, with a concomitant decrease in acceptance of hearts from donors with undesirable characteristics. Overall, predictors of heart non-use were similar across UNOS regions, although utilization varied between regions. Regional variation suggests a potential to improve heart acceptance rates in under-performing regions, and supports research and policy efforts aimed at establishing evidence-based criteria for donor heart evaluation and acceptance for transplantation.

Pursuing Expanded Criteria Donors as Candidates for Kidney Donation after Circulatory Death

Of the 119 310 people on the national transplant waiting list, 97 280 people are waiting for kidneys. There simply are not enough organs to meet the demand. Recognizing that 64% of the people waiting for kidney transplants are at least 50 years old, this organ procurement organization embarked on a study to evaluate the potential of increasing the number of viable kidneys available for transplant by pursuing expanded criteria donors as donation after circulatory death (ECD/DCD) candidates. Pursuing ECD/DCD donors resulted in 24 additional donors (50–67 years old), 48 kidneys recovered, 30 kidneys transplanted into 26 recipients (44–74 years old), 7 kidneys placed for research, and 11 kidneys discarded, yielding an overall 62% transplant rate, 15% research rate, and 23% discard rate. The overall discard rate including all donors in all classifications during the study period was 13.1% (122 discards from 928 kidneys) compared with 12.6% (111 discards from 880 kidneys) when the study set was excluded. Although ECD/DCD donors still had the highest discard rates of all the groups, the 0.5% increase in the overall discard rate due to pursuing ECD/DCD kidneys was considered insignificant when compared with the benefit of the 30 additional kidneys transplanted. Including potential ECD/DCD patients in the donor pool increases the number of viable kidneys available for transplant without significantly increasing the overall kidney discard rates.

Assessment of resident and fellow knowledge of the organ donor referral process

Maximizing deceased donation rates can decrease the organ shortage. Non-transplant physicians play a critical role in facilitating conversion of potential deceased donors to actual donors, but studies suggest that physicians lack knowledge about the organ donation process. As residency and fellowship are often the last opportunities for formal medical training, we hypothesized that deficiencies in knowledge might originate in residency and fellowship. We conducted a cross-sectional survey to assess knowledge about organ donation, experience in donor conversion, and opinions of the process among residents and fellows after their intensive care unit rotations at the Johns Hopkins Hospital. Of 40 participants, 50% had previously facilitated donor conversion, 25% were familiar with the guidelines of the organ procurement organization (OPO), and 10% had received formal instruction from the OPO. The median score on the knowledge assessment was five of 10; higher knowledge score was not associated with level of medical training, prior training in or experience with donor conversion, or with favorable opinions about the OPO. We identified a pervasive deficit in knowledge among residents and fellows at an academic medical center with an active transplant program that may help explain attending-level deficits in knowledge about the organ donation process.

Organ and tissue donation in clinical settings: a systematic review of the impact of interventions aimed at health professionals

In countries where presumed consent for organ donation does not apply, health professionals (HP) are key players for identifying donors and obtaining their consent. This systematic review was designed to verify the efficacy of interventions aimed at HPs to promote organ and tissue donation in clinical settings. CINAHL (1982 to 2012), COCHRANE LIBRARY, EMBASE (1974 to 2012), MEDLINE (1966 to 2012), PsycINFO (1960 to 2012), and ProQuest Dissertations and Theses were searched for papers published in French or English until September 2012. Studies were considered if they met the following criteria: aimed at improving HPs’ practices regarding the donation process or at increasing donation rates; HPs working in clinical settings; and interventions with a control group or pre-post assessments. Intervention behavioral change techniques were analyzed using a validated taxonomy. A risk ratio was computed for each study having a control group. A total of 15 studies were identified, of which only 5 had a control group. Interventions were either educational, organizational or a combination of both, and had a weak theoretical basis. The most common behavior change technique was providing instruction. Two sets of interventions showed a significant risk ratio. However, most studies did not report the information needed to compute their efficacy. Therefore, interventions aimed at improving the donation process or at increasing donation rates should be based on sound theoretical frameworks. They would benefit from more rigorous evaluation methods to ensure good knowledge translation and appropriate organizational decisions to improve professional practices.

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.

Honoring Deceased Donors with a Unique Family-Designed Statement Followed by a Moment of Silence: Effect on Donation Outcomes

Context

Studies indicate that donor families and hospital staff, particularly operating room staff, fear that organ donors will not be treated with dignity, honor, and respect.

Objective

The ritual of a unique, family-designed statement of honor followed by a 15-second moment of silence in the operating room before organ recovery was implemented to honor organ donors and their families. The purpose of this study was to describe the development of the ritual and to investigate its impact on donation rates in the California Transplant Donor Network's service area.

Design

Cross-sectional observational study.

Setting

The California Transplant Donor Network, an organ procurement organization.

Participants

58 organ donors and families in 39 donor hospitals.

Main Outcome Measures

Variables of interest included hospital rate of referral and of timely referral to their organ procurement organization, collaborative conversion rates, and donor families' response to implementation of the new ritual.

Results

The ritual was implemented in 2011 in several randomly selected hospitals locally. Seventy-one unique rituals were performed in 22 local hospitals in the trial period. No families or health care providers declined to participate. Families reported that the ritual honored their loved ones. Although the collaborative conversion rates were similar in hospitals before implementation (2010), implementation of the ritual affected donation rates in 2011.

Conclusions

The 15-second moment of silence honors deceased donors and their families and improves donation rates in donor hospitals.

The Organ Donation Breakthrough Collaborative: has it made a difference?

BACKGROUND

The Organ Donation Breakthrough Collaborative (ODBC) was established in 2003 to increase the number of transplantable organs in the United States. However, recent publications have suggested that the ODBC has not impacted donation conversion rates at local organ procurement organizations (OPOs). We sought to determine the impact, if any, of our becoming part of the ODBC on organ donation rates in our OPO or in our institution (Carolinas Medical Center [CMC]), particularly among minority donors.

METHODS

This is a retrospective review of data entered concurrently into a patient referral database maintained by our local OPO. Donation approach and consent rates were calculated. They were then analyzed by race and institution, and trends were analyzed over the study period of 2002 to 2010. Statistical differences between the various patient groups were determined by the chi-square test or the Fisher exact test. Statistical differences over time were determined by the Cochran-Armitage trend test.

RESULTS

From 2002 to 2010, 10,855 patients were screened by our OPO for potential organ donation. The overall approach rate was 13.4%, and the consent rate was 57.6%. An increase in approach and consent rates was noted beginning in 2004, but this increase was not sustained. Consent rates in general were higher for white patients than for black and Hispanic patients. Consent rates for CMC did increase significantly (P = .02), but they did not increase for the non-CMC hospitals. When analyzed by race, no significant changes were noted in consent rates over time. When analyzed by race and institution, the only statistically significant increase in consent rates occurred for white patients at CMC.

CONCLUSIONS

Since joining the ODBC, we have noted an increase in consent rates at a single institution (CMC), but no other significant changes. Greater emphasis should be placed on methods to increase and sustain consent rates for all racial groups in general, with a special emphasis on increasing consent rates in minority patients.

Declining liver utilization for transplantation in the United States and the impact of donation after cardiac death

Worsening donor liver quality resulting in decreased organ utilization may be contributing to the recent decline in liver transplants nationally. We sought to examine trends in donor liver utilization and the relationship between donor characteristics and nonuse. We used the United Network for Organ Sharing database to review all deceased adult organ donors in the United States from whom at least 1 solid organ was transplanted into a recipient. Trends in donor characteristics were examined. Multivariate logistic regression was used to evaluate the association between donor characteristics and liver nonuse between 2004 and 2010. Population attributable risk proportions were determined for donor factors associated with nonuse. We analyzed 107,259 organ donors. The number of unused livers decreased steadily from 1958 (66% of donors) in 1988 to 841 (15%) in 2004 but then gradually increased to 1345 (21%) in 2010. The donor age, the body mass index (BMI), and the prevalence of diabetes and donation after cardiac death (DCD) all increased over time, and all 4 factors were independently associated with liver nonuse. DCD had the highest adjusted odds ratio (OR) for nonuse, and the odds increased nearly 4-fold between 2004 [OR = 5.53, 95% confidence interval (CI) = 4.57-6.70] and 2010 (OR = 21.31, 95% CI = 18.30-24.81). The proportion of nonuse attributable to DCD increased from 9% in 2004 to 28% in 2010. In conclusion, the proportion of donor livers not used has increased since 2004. Older donor age, greater BMI, diabetes, and DCD are all independently associated with nonuse and are on the rise nationally. Current trends may lead to significant declines in liver transplant availability.

Morbidity and mortality in heart transplant candidates supported with mechanical circulatory support: is reappraisal of the current United network for organ sharing thoracic organ allocation policy justified?

BACKGROUND

Survival of patients on left ventricular assist devices (LVADs) has improved. We examined the differences in risk of adverse outcomes between LVAD-supported and medically managed candidates on the heart transplant waiting list.

METHODS AND RESULTS

We analyzed mortality and morbidity in 33,073 heart transplant candidates registered on the United Network for Organ Sharing (UNOS) waiting list between 1999 and 2011. Five groups were selected: patients without LVADs in urgency status 1A, 1B, and 2; patients with pulsatile-flow LVADs; and patients with continuous-flow LVADs. Outcomes in patients requiring biventricular assist devices, total artificial heart, and temporary VADs were also analyzed. Two eras were defined on the basis of the approval date of the first continuous-flow LVAD for bridge to transplantation in the United States (2008). Mortality was lower in the current compared with the first era (2.1%/mo versus 2.9%/mo; P<0.0001). In the first era, mortality of pulsatile-flow LVAD patients was higher than in status 2 (hazard ratio [HR], 2.15; P<0.0001) and similar to that in status 1B patients (HR, 1.04; P=0.61). In the current era, patients with continuous-flow LVADs had mortality similar to that of status 2 (HR, 0.80; P=0.12) and lower mortality compared with status 1A and 1B patients (HR, 0.24 and 0.47; P<0.0001 for both comparisons). However, status upgrade for LVAD-related complications occurred frequently (28%) and increased the mortality risk (HR, 1.75; P=0.001). Mortality was highest in patients with biventricular assist devices (HR, 5.00; P<0.0001) and temporary VADs (HR, 7.72; P<0.0001).

CONCLUSIONS

Mortality and morbidity on the heart transplant waiting list have decreased. Candidates supported with contemporary continuous-flow LVADs have favorable waiting list outcomes; however, they worsen significantly once a serious LVAD-related complication occurs. Transplant candidates requiring temporary and biventricular support have the highest risk of adverse outcomes. These results may help to guide optimal allocation of donor hearts.

Obstacles to corneal donation amongst hospice inpatients: a questionnaire survey of multi-disciplinary team member's attitudes, knowledge, practice and experience

BACKGROUND

Corneal donation is a sight restoring procedure. Internationally demand exceeds supply. It is a tissue that palliative care patients may be able to donate, yet donation rates from this group are low.

AIM

To explore the attitudes, knowledge, practice, and experience of corneal donation from hospice staff with direct clinical contact with patients.

DESIGN

Anonymous paper questionnaire with fixed response and free text components.

SETTING/PARTICIPANTS

Questionnaires were delivered to 704 clinical multi-disciplinary team members in 12 hospices within the Yorkshire Palliative Medicine Regional Learning Group, UK.

RESULTS

434 completed questionnaires were received. Most respondents believed that corneal donation is a rewarding opportunity of which patients and families should be aware, but over 90% of respondents rarely or never raised the topic, and only 33% felt that it was part of their role. Key reasons for not engaging in discussions were: concerns about the impact of the discussion on patients and families, a belief held by hospice staff that they lacked essential knowledge, negative experiences of corneal donation, concern about enucleation, a perception that donation is not part of hospice culture, low levels of training and the personal significance of eyes.

CONCLUSIONS

Despite positive staff attitudes towards corneal donation, many barriers to discussing donation were identified, which may reduce donation rates. This could be improved by local policies encompassing further education, prompts in documentation and availability of leaflets.

Benchmarking in the process of donation after brain death: a methodology to identify best performer hospitals

A benchmarking approach was developed in Spain to identify and spread critical success factors in the process of donation after brain death. This paper describes the methodology to identify the best performer hospitals in the period 2003-2007 with 106 hospitals throughout the country participating in the project. The process of donation after brain death was structured into three phases: referral of possible donors after brain death (DBD) to critical care units (CCUs) from outside units, management of possible DBDs within the CCUs and obtaining consent for organ donation. Indicators to assess performance in each phase were constructed and the factors influencing these indicators were studied to ensure that comparable groups of hospitals could be established. Availability of neurosurgery and CCU resources had a positive impact on the referral of possible DBDs to CCUs and those hospitals with fewer annual potential DBDs more frequently achieved 100% consent rates. Hospitals were grouped into each subprocess according to influencing factors. Hospitals with the best results were identified for each phase and hospital group. The subsequent study of their practices will lead to the identification of critical factors for success, which implemented in an adapted way should fortunately lead to increasing organ availability.
