Verification of Death by Neurologic Criteria: A Survey of 12 Organ Procurement Organizations Across the United States.

BACKGROUND: The Center for Medicare and Medicaid Services requires Organ Procurement Organizations (OPOs) to verify and document that any potential organ donor has been pronounced dead per applicable legal requirements of local, state, and federal laws. However, OPO practices regarding death by neurologic criteria (DNC) verification are not standardized, and little is known about their DNC verification processes. This study aimed to explore OPO practices regarding DNC verification in the United States. METHODS: An electronic survey was sent to all 57 OPOs in the United States from June to September 2023 to assess verification of policies and practices versus guidelines, concerns about policies and practices, processes to address concerns about DNC determination, and communication practices. RESULTS: Representatives from 12 OPOs across six US regions completed the entire survey; 8 of 12 reported serving > 50 referral hospitals. Most respondents (11 of 12) reported comparing their referral hospital's DNC policies with the 2010 American Academy of Neurology Practice Parameter and/or other (4 of 12) guidelines. Additionally, most (10 of 12) reported independently reviewing and verifying each DNC determination. Nearly half (5 of 12) reported concerns about guideline-discordant hospital policies, and only 3 of 12 thought all referral hospitals followed the 2010 American Academy of Neurology Practice Parameter in practice. Moreover, 9 of 12 reported concerns about clinician knowledge surrounding DNC determination, and most (10 of 12) reported having received referrals for patients whose DNC declaration was ultimately reversed. All reported experiences in which their OPO requested additional assessments (11 of 12 clinical evaluation, 10 of 12 ancillary testing, 9 of 12 apnea testing) because of concerns about DNC determination validity. CONCLUSIONS: Accurate DNC determination is important to maintain public trust. Nearly all OPO respondents reported a process to verify hospital DNC policies and practices with medical society guidelines. Many reported concerns about clinician knowledge surrounding DNC determination and guideline-discordant policies and practices. Educational and regulatory advocacy efforts are needed to facilitate systematic implementation of guideline-concordant practices across the country.

Pediatric donor heart utilization variability among organ procurement organizations.

BACKGROUND: Organ procurement organizations (OPOs) are responsible for the medical management of organ donors. Given the variability in pediatric donor heart utilization among OPOs, we examined factors that may explain this variability, including differences in donor medical management, organ quality, and candidate factors. METHODS: The Organ Procurement and Transplant Network database was queried for pediatric (<18 years) heart donors and candidates receiving pediatric donor heart offers from 2010 to 2019. OPOs were stratified by pediatric donor heart utilization rate, and the top and bottom quintiles were compared based on donor management strategies and outcomes. A machine learning algorithm, combining 11 OPO, donor, candidate, and offer variables, was used to determine factors most predictive of whether a heart offer is accepted. RESULTS: There was no clinically significant difference between the top and bottom quintile OPOs in baseline donor characteristics, distance between donor and listing center, management strategies, or organ quality. Machine learning modeling suggested neither OPO donor management nor cardiac function is the primary driver of whether an organ is accepted. Instead, number of prior donor offer refusals and individual listing center receiving the offer were two of the most predictive variables of organ acceptance. CONCLUSIONS: OPO clinical practice variation does not seem to account for the discrepancy in pediatric donor heart utilization rates among OPOs. Listing center acceptance practice and prior number of donor refusals seem to be the important drivers of heart utilization and may at least partially account for the variation in OPO heart utilization rates given the regional association between OPOs and listing centers.

Adjusting for race in metrics of organ procurement organization performance.

The Scientific Registry of Transplant Recipients has previously reported the effects of adjusting for demographic variables, including race, in the Centers for Medicare & Medicaid Services (CMS) organ procurement organization (OPO) performance metrics: donation rate and transplant rate. CMS chose not to adjust for most demographic variables other than age (for the transplant rate), arguing that there is no biological reason that these variables would affect the organ donation/utilization decision. However, organ donation is a process based on altruism and trust, not a simple biological phenomenon. Focusing only on biological impacts on health ignores other pathways through which demographic factors can influence OPO outcomes. In this study, we update analyses of demographic adjustment on the OPO metrics for 2020 with a specific focus on adjusting for race. We find that adjusting for race would lead to 8 OPOs changing their CMS tier rankings, including 2 OPOs that actually overperform the national rate among non-White donors improving from a tier 3 ranking (facing decertification without possibility of recompeting) to a tier 2 ranking (allowing the possibility of recompeting). Incorporation of stratified and risk-adjusted metrics in public reporting of OPO performance could help OPOs identify areas for improvement within specific demographic categories.

Pediatric Death and Family Organ Donation: Bereavement Support Services in One Pediatric Health System.

Health care providers need to support families and provide resources when facing their child's death and potential organ donation. Aims of this retrospective chart review in a tertiary health care system were: (1) describe characteristics of pediatric organ donors compared to those who were not; (2) determine differences between services utilized by families who selected organ donation versus those who did not. From 2017 to 2023 of 288 pediatric deaths, 76 were organ donors and 212 did not donate. Organ donors' mean age at admission was 6.3 ± 5.8 years. Thirty-four (44.7%) participated in Honor Walks. Significant differences existed between organ donors and non-organ donors in patients who were diagnosed with SIDS (3.9% vs 13.2%; P = .025). This study provides additional data to help further our understanding of bereavement support services for families making difficult decisions regarding organ donation.

COVID-19 in organ donors: An organ procurement organization perspective.

BACKGROUND: The COVID-19 pandemic presented a significant challenge for Organ Procurement Organizations (OPOs) with the use of SARS-CoV-2 positive donors varying widely. This study used detailed single OPO data to determine the success of using SARS-CoV-2 positive donors. METHODS: We performed a retrospective cohort study including all SARS-CoV-2 positive donors referred to the Gift of Life OPO from January 1, 2021, to June 30, 2023. Descriptive analyses were performed to characterize referral and organ utilization. RESULTS: There were 861 organ referrals with 1 positive SARS-Cov-2 test: 282 were ruled out with telephone evaluation, 431 referrals were ruled out with onsite evaluation ("evaluated nondonors") and 148 became donors. For donors who had both nasopharyngeal and lower respiratory testing completed, there was notable result discordance observed. Median cycle threshold (Ct) values were similar between donors and evaluated nondonors with no change in median donor Ct values over the study period. Transplanted organs from COVID-positive donors included 27 hearts, 88 livers, 5 pancreata, and 107 kidneys; no lung donation occurred. The proportion of COVID-positive donors significantly increased over the study period. CONCLUSION: This large volume donor referral study demonstrates increasing COVID-19 referrals progressing to donation over time, supporting the increased use of these donors for nonlung transplantation.

The effect of an organ procurement organization surgeon on pediatric organ utilization.

INTRODUCTION: Organ procurement organizations (OPO) have started to employ transplant-trained surgeons dedicated to organ procurement with the aim to increase allograft utilization and enhance the use of procured organs. We investigated the effects of an OPO-employed surgeon on the procurement and utilization of organs from pediatric donors within the Southwestern Transplant Alliance OPO. METHODS: OPO data were obtained for all procurements that were performed between 2014 and 2019. The analysis was performed to see if the presence of an OPO donor surgeon impacted the utilization of pediatric livers. Donor and recipient demographic data were examined between allografts procured with the presence of an OPO surgeon (OPO-Present) and those without an OPO surgeon (OPO-Absent). A p-value of <.05 was considered significant. RESULTS: Of 149 pediatric procurements, 91 included an OPO-donor surgeon. In procurements with OPO-Present, donors were younger (8.2 vs. 11.2, p < .05) and had longer distances to travel to the recipient center (334 vs. 175 miles p < .05), but had comparable cold ischemic times. In terms of organ share type, more OPO-Present livers were shared nationally and there was no difference in discard rate between OPO-Present and OPO-Absent procurements. Finally, OPO-Present livers were more likely to be transplanted to pediatric recipients compared to OPO-Absent (47.3% vs. 24.1% p < .05). CONCLUSION: The presence of an OPO surgeon has impacted organ utilization, leading to increased transplantation of pediatric livers in pediatric recipients, and has expanded the geographical share of pediatric livers.

Progress in quality management and control of donor organ procurement in foreign countries / 器官移植

Since the 20th century, organ transplantation has become a breakthrough technology to effectively save the lives of patients with end-stage organ failure, which has significantly enhanced the quality of life of patients. Organ donation is an important source of organ transplantation. Improving the quality of donor organ procurement is the key to promote the translation of donor organs and improve the prognosis of organ transplantation recipients. The United States, Spain and other countries have put forward a series of policies and standards in the quality management and control of donor organ procurement and achieved positive results. In this article, related concepts of medical quality management and control, advanced strategies and models of international donor organ procurement quality management, and quality control measures of Organ Procurement Organization, donors and donor organs were reviewed, aiming to provide reference for establishing a quality management and control system of donor organs with "Chinese characteristics" and advancing high-speed and high-quality development of donor organ procurement.

What is visible is fixable: Visual dashboards for multi-domain assessment of organ procurement organization performance.

With stakeholder focus on the United States organ procurement system, there is a need for tools that permit comparative assessment of organ procurement providers. We developed a public-facing dashboard for organ procurement organizations (OPOs), using data from multiple sources, to create an online, readily accessible visualization of OPO practice conditions and performance for the period 2010-2020. With this tool, OPOs can be compared on the CMS metric of donors procured per 100 donation-consistent deaths, as well as donation after circulatory death procurement, procurement of older and minority patient populations, procurement in smaller hospitals, and procurement of patients without a significant drug history. Patterns of higher performance were identified, and 74% of differences in overall donor procurement rates could be explained using model variables. Procurement differences were affected to a greater and more reproducible degree by OPO performance among Black and non-White patient populations, as well as in smaller hospitals, than by donation service area characteristics. Dashboards such as ours support OPOs and stakeholders in quality improvement actions, through leveraging benchmarked performance data among organ procurement clinical providers.

Clinical outcomes of a prospective randomized comparison of bioreactance monitoring versus pulse-contour analysis in a stroke-volume based goal-directed fluid resuscitation protocol in brain-dead organ donors.

Eighty percent of brain-dead (BD) organ donors develop hypotension and are frequently hypovolemic. Fluid resuscitation in a BD donor is controversial. We have previously published our 4-h goal-directed stroke volume (SV)-based fluid resuscitation protocol which significantly decreased time on vasopressors and increased transplanting four or more organs. The SV was measured by pulse-contour analysis (PCA) or an esophageal doppler monitor, both of which are invasive. Thoracic bioreactance (BR) is a non-invasive portable technology that measures SV but has not been studied in BD donors. We performed a randomized prospective comparative study of BR versus PCA technology in our fluid resuscitation protocol in BD donors. Eighty-four donors (53.1%) were randomized to BR and 74 donors to PCA (46.8%). The two groups were well matched based on 24 demographic, social, and initial laboratory factors, without any significant differences between them. There was no difference in the intravenous fluid infused over the 4-h study period [BR 2271 ± 823 vs. PCA 2230 ± 962 mL; p = .77]. There was no difference in the time to wean off vasopressors [BR 108.8 ± 61.8 vs. PCA 150.0 ± 68 min p = .07], nor in the number of donors off vasopressors at the end of the protocol [BR 16 (28.6%) vs. PCA 15 (29.4%); p = .92]. There was no difference in the total number of organs transplanted per donor [BR 3.25 ± 1.77 vs. PCA 3.22 ± 1.75; p = .90], nor in any individual organ transplanted. BR was equivalent to PCA in clinical outcomes and provides a simple, non-invasive, portable technology to monitor fluid resuscitation in organ donors.

When pancreata fly: Outcomes and lessons learned from the development of a Pancreas Transplant Import Program.

BACKGROUND: To address long waitlist times and increase pancreas transplantation, our center has implemented a protocol for long-distance importation of pancreata. METHODS: We conducted a retrospective review of pancreas transplantation at our institution from January 1, 2014, the start of our importation program, through September 30, 2021. Outcomes were compared between locally procured grafts and imported grafts, defined as grafts procured greater than 250 nautical miles (NM) from our center. RESULTS: Eighty-one patients underwent pancreas transplantation during the study time period; 19 (23.5%) received imported grafts. There were no significant differences in recipient demographics or type of transplant received. Mean distance of import was 644.2 ± 234.0 NM. Imported grafts were more likely to be from pediatric donors <18 years old (p = .02) and a significantly higher proportion of imported grafts came from donors weighing <30 kg (26.3 vs. 3.2%, p = .007). Cold ischemic time was longer for imported grafts than for local grafts (13.4 ± 2.3 h vs. 9.8 ± 2.2 h, p < .01). There was no significant difference in deaths or graft losses within 90 days or at 1 year between groups. CONCLUSION: Centers should consider expanding criteria for acceptance of imported pancreata to increase the number of transplants and combat organ nonutilization.

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.

Self-perceived role and knowledge of community pharmacists in organ donation.

BACKGROUND: Although a majority of North Americans is in favor of organ donation, registration remains challenging. Community pharmacists are highly accessible frontline health care professionals that could contribute to a new common registration donation consent system. AIM: The objective of the study was to assess self-perceived professional role and organ donation knowledge of community pharmacists in Quebec. METHOD: We designed a telephone interview survey using a three round modified Delphi process. Following questionnaires testing, we randomly sampled 329 community pharmacists in Quebec. Following administration, we validated the questionnaire by conducting an exploratory factorial analysis using principal component followed by a varimax rotation and rearranging domains and items accordingly. RESULTS: A total of 443 pharmacists were contacted, 329 provided answers to the self-perception role and 216 of them completed the knowledge questionnaire. Overall, community pharmacists of Quebec had a positive view on organ donation and demonstrated interest in acquiring knowledge. Respondents have identified lack of time and high pharmacy attendance as non-limiting barriers to implementing the intervention. The average score on the knowledge questionnaire was 61.2%. CONCLUSION: With the implementation of an appropriate education program to address this knowledge gap, we believe that community pharmacists could be key players in registered organ donation consent.

Donation after circulatory death heart transplantation using normothermic regional perfusion:The NYU Protocol.

Objective: This study aimed to evaluate the impact of cardiopulmonary bypass for thoraco-abdominal normothermic regional perfusion on the metabolic milieu of donation after cardiac death organ donors before transplantation. Methods: Local donation after cardiac death donor offers are assessed for suitability and willingness to participate. Withdrawal of life-sustaining therapy is performed in the operating room. After declaration of circulatory death and a 5-minute observation period, the cardiac team performs a median sternotomy, ligation of the aortic arch vessels, and initiation of thoraco-abdominal normothermic regional perfusion via central cardiopulmonary bypass at 37 °C. Three sodium chloride zero balance ultrafiltration bags containing 50 mEq sodium bicarbonate and 0.5 g calcium carbonate are infused. Arterial blood gas measurements are obtained every 15 minutes after every zero balance ultrafiltration bag is infused, and blood is transfused as needed to maintain hemoglobin greater than 8 mg/dL. Cardiopulmonary bypass is weaned with concurrent hemodynamic and transesophageal echocardiogram evaluation of the donor heart. The remainder of the procurement, including the abdominal organs, proceeds in a similar controlled fashion as is performed for a standard donation after brain death donor. Results: Between January 2020 and May 2022, 18 donation after cardiac death transplants using the thoraco-abdominal normothermic regional perfusion protocol were performed at our institution. The median donor age was 42.5 years (range, 20-51 years), and 88.9% (16/18) were male. The mean total donor cardiopulmonary bypass time was 88.8 ± 51.8 minutes. At the beginning of cardiopulmonary bypass, the average donor lactate was 9.4 ± 1.5 mmol/L compared with an average final lactate of 5.3 ± 2.7 mmol/L (P<.0001). The average beginning potassium was 6.5 ± 1.8 mmol/L compared with an average end potassium of 4.2 ± 0.4 mmol/L (P<.0001) . The average beginning hemoglobin was 6.8 ± 0.7 g/dL, and the average end hemoglobin was 8.2 ± 1.3 g/dL (P<.001) . On average, donation after cardiac death donors received transfusions of 2.3 ± 1.5 units of packed red blood cells. Of the 18 donors who underwent normothermic regional perfusion, all hearts were deemed suitable for recovery and successfully transplanted, a yield of 100%. Other organs successfully recovered and transplanted include kidneys (80.6% yield), livers (66.7% yield), and bilateral lungs (27.8% yield). Conclusions: The use of cardiopulmonary bypass for thoraco-abdominal normothermic regional perfusion is a burgeoning option for improving the quality of organs from donation after cardiac death donors. Meticulous intraoperative management of donation after cardiac death donors with a specific focus on improving their metabolic milieu may lead to improved graft function in transplant recipients.

Factors influencing organ donation in Fujian's Organ Procurement Organization: A retrospective study.

INTRODUCTION: The Organ Procurement Organization (OPO) was established in August 2018. The organization's workload, work efficiency, and quality control of organ donation and procurement have continuously improved, making it one of the most successful OPOs in Fujian Province. This study explores the factors that influence the success and failure of organ donation in Fujian Province, China. METHODS: Data from 236 potential organ donors registered at an OPO in Fujian Province between January 2020 and May 2022 were retrospectively analyzed. RESULTS: Among the 236 potential organ donors, 71 cases of organ donation were successful (30.08% conversion rate). Univariate analysis showed that demographic factors, such as differences in sex, age, marital status, and domicile location, were significantly associated with successful organ donation (p < .05). Among hospital-related factors, differences in hospital departments were significant (p < .05). Considering disease-related factors, spontaneous respiration was significant (p < .05). For factors related to organ donation, differences in coordinators were significant (p < .05). Multivariate analysis showed that age, domicile location, spontaneous respiration, and coordinators influenced organ donation success (p < .05). Multifactor analysis revealed that factors, such as age ≤50 years, domicile location in other provinces, no spontaneous respiration, and highly skilled coordinators, could promote successful organ donation. CONCLUSIONS: Programs should clarify the screening criteria for key potential organ donors, enhance the promotion and popularization of organ donation, and boost the number and professional skills of organ donation coordinators to improve the organ donation conversion rate.

The 20-year paradigm shift toward organ recovery centers: 2500 donors at Mid-America Transplant and broader adoption across the United States.

On March 1, 2001, Mid-America Transplant, the organ procurement organization (OPO) located in St Louis, Missouri, performed the first organ recovery of a brain-dead donor in a hospital-independent, free-standing, organ recovery center (ORC), with successful transplantation of a liver. This was the inception of a paradigm shift in donor management and organ procurement, moving away from the traditional method of using the donor hospital. In the last 20 years, many advances have occurred in the ORC. Brain-dead donors are moved within hours of authorization to fully equipped intensive care units. Some ORCs are equipped with computed tomography scanners, portable radiography, laboratory facilities, bronchoscopy, and a cardiac catheterization laboratory. ORCs have dedicated surgical suites, and operating time is frequently during the day and is rarely delayed. Donor management in an ORC is more consistent, efficient, and effective than that in a donor hospital, and studies have demonstrated increased organ yield. Multiple studies have demonstrated a cost benefit of an ORC as well as providing an ideal environment for donor research studies. Currently, there are 24 of 57 OPOs that are using an independent or hospital-based ORC to manage their donors. We review the history and describe the current state of ORCs.

Exploration on standardized management of ethical review of organ donation after citizen’s death / 器官移植

Objective To explore the standardized management mode of the Ethics Committee for organ donation after citizen’s death in hospitals. Methods The situations of ethical review before and after the standardized adjustment of the Ethics Committee of human organ donation in the First Affiliated Hospital of Chongqing Medical University were retrospectively analyzed. Baseline data of donors before and after standardized adjustment of the Ethics Committee of human organ donation were compared. The influence of standardized adjustment of the Ethics Committee on the attendance rate of committee members and duration of ethical review were analyzed. Results No significant differences were observed in donors' ethical review data, such as gender, age and death determination, before and after standardized adjustment of Ethics Committee structure (all P>0.05). Significant difference was noted regarding the cause of death in ethical review (P<0.05). Univariate analysis showed that there were significant differences in the impact of Ethics Committee standardization adjustment and cause of death on the attendance rate of committee members (both P<0.05). Multivariate analysis revealed that gender, cause of death and standardized adjustment of the Ethics Committee were the influencing factors of the attendance rate of committee members, and the attendance rate of committee members after standardized adjustment was higher than that before adjustment (P<0.05). Univariate analysis showed that there were statistically significant differences in the effects of Ethics Committee standardized adjustment, attendance rate of committee members and cause of death on the duration of ethical review (all P<0.05). Multivariate analysis indicated that standardized adjustment of the ethics committee was the influencing factor of the duration of ethical review, and the duration of ethics review after standardized adjustment was shorter than that before adjustment (P<0.05). Conclusions Appropriate arrangement of the total number of ethics committee members and standardizing the review process may improve the efficiency of ethical review. Scientific evaluation mechanism for ethical committee members should be established by dynamically adjusting the ethical committee members, clarifying the responsibilities and tasks of members and secretaries, aiming to further improve standardized management level of ethical review for organ donation after citizen’s death.

Establishment of a long-term operation mechanism for sustainable development of united OPO / 器官移植

Human Organ Procurement Organization (OPO) is an indispensable part of organ donation. In recent years, with rapid development of organ donation in China, united OPO has been established based on China's national conditions and establishment of global OPO. This innovative model serves as favorable supplement and exploration for the development of OPO, promoting the development of organ donation to enter a new stage. However, there are still some shortcomings during the process of development. Efforts should be made to catch up with the development of organ donation, aim at long-term goals, and promote development in a targeted manner. In this article, by analyzing the advantages and disadvantages of united OPO in the development of organ donation, the establishment of a long-term operation mechanism of united OPO was analyzed from policy support, talent training, technology upgrading, quality control, ethical review, financial management and full-course supervision, aiming to provide reference for further development of united OPO in China.

The only way for the development of organ transplantation in China — Systematization of organ transplantation disciplines, specialization of organ donation and disciplinarization of OPO construction / 中华器官移植杂志

The problems that China's organ transplantation development facing are the disciplinary construction of Organ Procurement Organization (OPO), the cost of organ donation and financial management, and the construction of organ transplantation technology system under the "Chinese model". As long as we stick to the development path of specialization of organ donation, disciplinarization of OPO construction and systematization of organ transplantation, we will definitely be able to create Chinese technology, Chinese standards, Chinese team and Chinese system with Chinese characteristics and advancement.
