    目的:本研究探讨了体外心肺复苏(ECPR)治疗难治性院外心脏骤停(OHCA)患者器官捐献的演变,并评估了成熟的ECPR计划对公共卫生的益处。
    方法:本回顾性研究,单中心研究纳入了OHCA患者(2016-2023年),这些患者大多具有初始可电击节律,并接受了ECPR治疗.分析了这些年非幸存者的器官捐赠率。ECPR的公共卫生益处是由1-2类脑功能幸存者和捐赠至少1个实体器官的非幸存者的总和的比率决定的。对所有ECPR患者。使用线性回归分析每年的时间趋势。
    结果:在研究期间出现难治性OHCA的419例ECPR患者中,116例神经系统完整存活(27.7%)。在非幸存者中(n=303),41个(13.5%)的家庭同意器官捐赠(平均年龄51岁,75.6%男性)和38例患者的器官被收获,导致73个接受者的74个器官移植。移植器官包括43个肾脏(58.1%),27肝(36.5%),3肺(4%),和1个心脏(1.4%),平均2.4±0.9接受器官/供体。自ECPR计划启动以来,器官供体和成功移植的数量与年份呈正相关(ptrend=0.009,ptrend=0.01)。总的来说,189名患者(116名幸存者,73个器官接受者)受益于ECPR,实现无器官衰竭的生存。ECPR的累积公共卫生益处,考虑116名幸存者和38名捐献者,占36.8%.
    结论:已建立的ECPR计划的公共健康益处超出了ECPR患者个体的生存,形成一个新的,以前被低估的移植供体来源。
    OBJECTIVE: This study explores the evolution of organ donation from patients treated with extracorporeal-cardiopulmonary-resuscitation (ECPR) for refractory out-of-hospital-cardiac-arrest (OHCA) and evaluates the public health benefits of a mature ECPR program.
    METHODS: This retrospective, single-center study included OHCA patients (2016-2023) who had mostly initial shockable rhythms and were treated with ECPR. Organ donation rates from non-survivors through these years were analyzed. The public health benefit of ECPR was determined by the ratio of the sum of survivors with Cerebral Performance Category 1-2 and non-survivors who donated at least 1 solid organ, to the total ECPR patients. Temporal trends were analyzed yearly using linear regression.
    RESULTS: Out of 419 ECPR patients presenting with refractory OHCA over the study period, 116 survived neurologically intact (27.7%). Among non-survivors (n=303), families of 41 (13.5%) consented to organ donation (median age 51 years, 75.6% male) and organs from 38 patients were harvested, leading to 74 organ transplants to 73 recipients. The transplanted organs included 43 kidneys (58.1%), 27 livers (36.5%), 3 lungs (4%), and 1 heart (1.4%), averaging 2.4±0.9 accepted organs/donor. The number of organ donors and successful transplants correlated positively with the years since the ECPR program\'s initiation (ptrend=0.009, ptrend=0.01). Overall, 189 patients (116 survivors, 73 organ recipients) benefited from ECPR, achieving organ-failure-free survival. The cumulative public health benefit of ECPR, considering the 116 survivors and 38 donors was 36.8%.
    CONCLUSIONS: The public health benefits of an established ECPR program extend beyond individual ECPR patient survival, forming a new, previously under-recognized source of transplant donors.

    背景:2018年UNOS分配政策将优先考虑的地理边界更改为器官分配,这种变化的影响是广泛的。这项调查的目的是分析供体移植中心距离在分配政策改变前后的器官旅行和相应结果的变化。
    方法:UNOS数据库用于识别2016年至2021年所有等待心脏移植的成年患者。移植中心根据供体心脏移动的平均距离进行分组,基于它们是否从>250英里外接受了超过50%的器官。提供了等待名单和移植患者的描述性统计数据。回归分析建模候补死亡率,移植的发生率,总生存率,和移植物存活。
    结果:平均旅行距离较长的中心年平均移植量较高,等待名单的总天数减少(86.6vs.149.2天),冷缺血时间增加(3.6vs.3.2h),移植后总生存率或移植物生存率没有显着差异。
    结论:在保留移植后结局的同时减少候补时间的益处广泛扩展。在新的器官采购和保存技术时代,当我们修改器官移植政策时,在这项调查中观察到的趋势将是有用的。
    BACKGROUND: The 2018 UNOS allocation policy change deprioritized geographic boundaries to organ distribution, and the effects of this change have been widespread. The aim of this investigation was to analyze changes in donor transplant center distance for organ travel and corresponding outcomes before and after the allocation policy change.
    METHODS: The UNOS database was utilized to identify all adult patients waitlisted for heart transplants from 2016 to 2021. Transplant centers were grouped by average donor heart travel distance based on whether they received more or less than 50% of organs from >250 miles away. Descriptive statistics were provided for waitlisted and transplanted patients. Regression analyses modeled waitlist mortality, incidence of transplant, overall survival, and graft survival.
    RESULTS: Centers with a longer average travel distance had a higher mean annual transplant volume with a reduction in total days on a waitlist (86.6 vs. 149.2 days), an increased cold ischemic time (3.6 vs. 3.2 h), with no significant difference in post-transplant overall survival or graft survival.
    CONCLUSIONS: The benefits of reducing waitlist time while preserving post-transplant outcomes extend broadly. The trends observed in this investigation will be useful as we revise organ transplant policy in the era of new organ procurement and preservation techniques.

    尽管儿科器官捐赠只占整个器官捐赠的一小部分,儿童和青少年对捐赠的器官库做出了重大贡献。在这项研究中,从儿童和青少年收集了252个实体器官。两百零两名受者从62名儿科器官捐献者中受益,接受者/捐赠者比率为3.3。
    背景:儿科器官捐献者代表了死者捐献者库的一小部分,但很重要。在移植等待名单中帮助儿童和成人。尽管如此,儿科捐赠仍然是一个被忽视的研究课题。
    方法:回顾性,单中心,描述性研究。所有18岁以下的脑死亡患者于1月1日之间入住重症监护病房(ICU),2006年12月31日,包括2021年,以及有资格获得器官捐赠的人。
    结果:在2006年1月至2021年12月期间,200名儿童/青少年在ICU死亡。从那些,62名患者(31%)被认为有资格进行器官捐赠。捐献者死亡时的平均年龄为8.8岁。63%为男性。最常见的死亡原因是创伤性脑损伤(n=36)。收集了250个器官,使202人受益,接受者/捐赠者比率为3.3。肾脏是最常见的器官捐献(n=116),其次是肝脏(n=56)和心脏(n=34)。每个孩子捐献的器官的中位数是四个,最小1个器官,最大8个器官。
    结论:儿科器官捐献只占整个器官捐献的一小部分,但是儿童和青少年对他们拯救的生命有重要影响。儿科器官捐赠领域需要更多的研究,以更好地了解儿科人群对等待器官的成年人和儿童的贡献。
    Although pediatric organ donation represents a small proportion of overall organ donation, children and adolescents make a significant contribution to the pool of donated organs. In this study 252 solid organs were collected from children and adolescent. Two hundred and two recipients benefited from 62 pediatric organ donors, with a recipient/donor ratio of 3.3.
    BACKGROUND: Pediatric organ donors represent a small but important portion of the deceased donor pool, helping both children and adults in the transplant waitlist. Despite this, pediatric donation remains an overlooked subject of research.
    METHODS: Retrospective, single‐center, descriptive study. All brain death patients under 18 years old who were admitted to the Intensive Care Unit (ICU) between January 1st, 2006, and December 31st, 2021, and who were eligible for organ donation were included.
    RESULTS: Between January 2006 and December 2021, 200 children/adolescent died in the ICU. From those, 62 patients (31%) were considered eligible for organ donation. The mean age of the donors at the time of death was 8.8 years. Sixty‐three per cent were male. The most frequent cause of death was traumatic brain injury (n = 36). Two hundred and fifty organs were collected benefitting 202 persons with a recipient/donor ratio of 3.3. Kidneys were the most frequent organ donated (n = 116), followed by liver (n = 56) and heart (n = 34). The median number of organs donated per child was four, with a minimum of 1 organ and maximum of 8.
    CONCLUSIONS: Pediatric organ donation represents a small proportion of overall organ donation, but children and adolescents have important impact on the lives they save. The field of pediatric organ donation needs more research to better understand the contribution of the pediatric population to both adults and children who wait for an organ.

    本文探讨了是否应允许直接捐赠死者器官,如果是这样,在什么条件下。虽然器官捐赠和分配系统必须公平和透明,防止家庭中的定向捐赠可能是“一个想法太多”吗?我们通过提供医疗和法律背景的描述来进行,然后确定定向捐赠涉及的主要道德问题,然后通过一系列类似于实践中遇到的假设案例来探索这些。最终,我们设定了某些条件,在这些条件下,定向死者捐赠在道德上是可以接受的。我们的讨论仅限于将器官分配给已经在等待名单上的接受者。
    This paper explores whether directed deceased organ donation should be permitted, and if so under which conditions. While organ donation and allocation systems must be fair and transparent, might it be \"one thought too many\" to prevent directed donation within families? We proceed by providing a description of the medical and legal context, followed by identification of the main ethical issues involved in directed donation, and then explore these through a series of hypothetical cases similar to those encountered in practice. Ultimately, we set certain conditions under which directed deceased donation may be ethically acceptable. We restrict our discussion to the allocation of organs to recipients already on the waiting list.

    SimonRippon,修正了之前关于卖肾的说法,现在声称提供涉及侵入行为的表现,当延伸到压力下的人时,构成一种权利侵犯,不尊重的要求。由于涉及肾脏销售的报价如此合格,Rippon找到了禁止它们的初步理由。本文对Rippon的论点提出了四个独立的反对意见:“不尊重的要求”的说法令人难以置信地谴责了肾脏捐赠和肾脏销售;对身体入侵进行自主否决控制的规范性重要性并没有合理地保障在压力下不扩大侵入性提议的权利;不尊重的要求很容易转化为无害的提议;禁令的福利成本比Rippon承认的要高。
    Simon Rippon, revising an earlier argument against kidney sales, now claims that offers involving the performance of invasive acts, when extended to people under pressure, constitute a kind of rights violation, Impermissibly Disrespectful Demands. Since offers involving kidney sales so qualify, Rippon finds prima facie reason to prohibit them. The present article levels four independent objections to Rippon\'s argument: the account of Impermissibly Disrespectful Demands implausibly condemns kidney donation as much as kidney sales; the normative importance of having autonomous veto control over bodily incursions does not plausibly underwrite a right to not be extended invasive offers under pressure; Impermissibly Disrespectful Demands can easily be transformed into innocuous offers; and the prohibition has greater welfare costs than Rippon acknowledges.

    背景:2020年5月,英国实施了“视为同意”立法,使个人更容易捐献器官,并在活着的时候传达他们的决定。家庭应该支持这个决定,但如果他们不同意,仍然可以推翻它。我们的目标是在与家人接触器官捐赠时,更多地了解这种角色的变化。
    方法:使用半结构化家庭访谈的定性研究,来自护士的反馈,与审计数据的比较,和公众参与。我们使用具有卫生系统观点和功利主义理论的框架分析来探索该法律是否有效。
    结果:103名参与者接受了83例潜在捐赠案例的访谈。在31/83(37%)的案例中,捐赠得到了完全支持,在41/83(49%)病例中,家庭支持取回一些器官,组织和程序,在11/83(13%)病例中,家庭完全下降。解释为什么法律尚未起作用的主题包括:理解和同意家庭的角色,关于被视为同意的困惑,不支持死者表达的决定,器官捐献太有害了,捐赠途径的不同经历,从生命结束过渡到器官捐赠讨论,“同意”的经历,文书工作和流程。家庭经常质疑他们的亲戚是否想做手术,而不是支持为挽救生命而死亡的人。
    结论:家庭利用他们在重症监护中相对死亡的独特经历来创建替代叙述,从而结果满足他们自己的效用,而不一定是潜在捐赠者的效用。正在进行的新的公共媒体活动旨在更加支持器官捐赠,这对移植接受者来说是一种好处,可以帮助家庭克服他们在床边遇到的许多困难。
    结论:软退出政策并未授权护士帮助最脆弱的家庭增加对死者器官捐赠的支持和同意。
    BACKGROUND: In May 2020, England implemented \"deemed consent\" legislation, to make it easier for individuals to donate their organs and convey their decision when alive. Families are supposed to support the decision but can still override it if they disagree. We aimed to learn more about this changed role when families were approached about organ donation.
    METHODS: A qualitative study using semi-structured interviews with families, feedback from nurses, comparisons with audit data, and public involvement. We used framework analysis with a health systems perspective and utilitarian theory to explore if the law worked.
    RESULTS: 103 participants were interviewed representing 83 potential donation cases. In 31/83 (37%) cases donation was fully supported, in 41/83 (49%) cases families supported retrieval of some organs, tissues and procedures, and in 11/83 (13%) cases families declined completely. Themes explaining why the law was not (yet) working included: Understanding and agreeing the family\'s role, confusion about deemed consent, not supporting the deceased expressed decisions, organ donation as too much of a harm, the different experiences of donation pathways, transition from end-of-life to organ donation discussions, experiences of \'consent\', paperwork and processes. Families frequently questioned if their relative wanted to have a surgery rather than supporting the person who died to save lives.
    CONCLUSIONS: Families use the unique experience of their relative dying in intensive care to create alternate narratives whereby the outcome satisfies their own utility and not necessarily those of the potential donor. New public ongoing media campaigns crafted to be more supportive of organ donation as a benefit to transplant recipients could help families overcome the many difficulties they encounter at the bedside.
    CONCLUSIONS: The soft opt-out policy has not empowered nurses to help families at their most vulnerable to increase their support for and consent to deceased organ donation.

    器官移植是终末期器官衰竭患者的救命治疗,但是美国面临可用器官的短缺。美国的政策激励识别所有康复器官的接受者。技术进步扩大了供体器官的生存能力,为长途运输和国际共享创造新的机会。我们的目标是评估已故美国捐赠者向国外候选人的器官出口,分配政策的一个组成部分,在没有合适的国内候选人的情况下允许。根据2014年1月至2023年9月的国家SRTR数据,回收了388342个器官进行移植。出口511(0.13%)。大多数输出的器官是肺(80%)。出口的肺捐献者年龄较大(41vs.34年,p<0.001),更可能是丙型肝炎阳性(22%vs.4%,p<0.001),循环性死亡后更有可能捐献者(20%对7%,p<0.001)。最终出口的肺提供给美国的PTR(中位数=65)比美国保留的肺(非出口和出口OPO回收的肺的中位数=21和41;p<0.001)。我们的研究强调了进一步研究和明确政策举措的必要性,以平衡跨境共享的好处,同时考虑在美国境内进行更积极的器官分配的潜在机会。
    Organ transplantation is a life-saving treatment for end-stage organ failure patients, but the US faces a shortage of available organs. US policies incentivize identifying recipients for all recovered organs. Technological advancements have extended donor organ viability, creating new opportunities for long-distance transport and international sharing. We aimed to assess organ exports from deceased US donors to candidates abroad, a component of allocation policy allowed without suitable domestic candidates. Based on national SRTR data from January 2014-September 2023, 388,342 organs were recovered for transplantation, with 511(0.13%) exported. Most exported organs were lungs(80%). Exported lung donors were older(41 vs. 34 years,p<0.001), more likely Hepatitis-C positive(22% vs. 4%,p<0.001), and more likely donors after circulatory death(20% vs 7%,p<0.001). Lungs that were eventually exported were offered to more US PTRs (median=65) than those kept in the US(median=21 and 41 for lungs recovered by non-exporting and exporting OPOs;p<0.001). Our study highlights the necessity for further research and clear policy initiatives to balance the benefits of cross-border sharing while considering potential opportunities for more aggressive organ allocation within the US.

    我们旨在评估医院特征对检测到的可能脑死亡捐献者的结果的影响,在我们在伊朗的器官采购网络中。数据是通过每天两次致电57家医院的重症监护病房和急诊科,为期一年。在医院正式宣布脑死亡之前,当怀疑脑死亡时,捐赠团队就介入了。数据按医院规模分类,神经外科/创伤部门的存在,所有权,和推荐网站。在813个可能的捐赠者中,315人被宣布脑死亡,203人符合捐赠条件.进行家庭访谈后(同意率:62.2%),102名符合条件的捐赠者成为实际捐赠者(转化率:50.2%)。虽然医院所有权和创伤/神经外科护理的存在并不影响捐赠,急诊科早期转诊有积极作用.因此,我们强烈建议在急诊室优先确定可能的捐赠者身份,并尽早让器官捐赠团队参与进来。每天两次呼吁捐赠者身份的使用可能有助于医院捐赠率的一致性,因为这种方法更早地涉及捐赠团队,并减轻了医院特征的影响。早期发现急诊科可能的捐赠者对于提高捐赠率至关重要。
    We aimed to assess the impact of hospital characteristics on the outcomes of detected possible brain-dead donors, in our organ procurement network in Iran. Data was collected through twice-daily calls with 57 hospitals\' intensive care units and emergency departments over 1 year. The donation team got involved when there was suspicion of brain death before the hospital officially declared it. The data was categorized by hospital size, presence of neurosurgery/trauma departments, ownership, and referral site. Out of 813 possible donors, 315 were declared brain dead, and 203 were eligible for donation. After conducting family interviews (consent rate: 62.2%), 102 eligible donors became actual donors (conversion rate: 50.2%). While hospital ownership and the presence of trauma/neurosurgery care did not affect donation, early referral from the emergency department had a positive effect. Therefore, we strongly recommend prioritizing possible donor identification in emergency rooms and involving the organ donation team as early as possible. The use of twice-daily calls for donor identification likely contributed to the consistency in donation rates across hospitals, as this approach involves the donation team earlier and mitigates the impact of hospital characteristics. Early detection of possible donors from the emergency department is crucial in improving donation rates.

    不断增加的人口和已确定的潜在器官捐献者的短缺导致等待器官移植的名单持续增长。循环性死亡(DCD)后捐赠是一种旨在满足对可移植器官需求的方法。然而,它给护理带来了新的挑战,缺乏调查护士对DCD的态度和知识的研究。
    本研究的目的是确定和描述重症监护护士(ICNs)知识,态度,以及在瑞典国家实施之前对DCD的看法。
    这项研究采用了横截面混合方法设计。采用了一种方便的抽样方法,针对在瑞典四个重症监护病房工作的ICNs。开发了一种特定于研究的工具,包括固定和自由文本问题。51个ICNs参加了会议。数据进行了描述性分析,采用Spearman相关性进行相关性分析。对自由文本答案进行了定性评估和分析。进行了综合分析,以综合定量和定性结果。
    百分之五十三报告对DCD的了解有限。以前接受过DCD教育的护士的知识水平明显更高(r=.380,p=.006),更多地参与关于器官捐赠的公开辩论(r=.423,p=.002),并更彻底地考虑了DCD的伦理方面(r=.386,p=.022)。定性分析确定了四个关键类别:团队的重要性,需要进行伦理讨论,增加对DCD的了解,和未回答的问题和未满足的需求。综合分析强调了有针对性的教育的必要性,明确的指导方针,以及正在进行的伦理讨论,为ICU护士做好DCD的准备。
    受过器官捐献者护理教育的护士对实施DCD有更好的知识和更积极的态度。该研究还强调了跨专业团队合作在DCD实施中的重要性。研究结果表明,DCD教育可以改善DCD捐赠者的识别和实施,解决全球可移植器官短缺的问题。
    UNASSIGNED: An increasing population and a shortage of identified potential organ donors are causing the waiting list for organ transplants to grow continuously. Donation after circulatory death (DCD) is a method aimed at meeting the demand for transplantable organs. However, it presents new challenges in nursing care, and there is a lack of studies investigating nurses\' attitudes and knowledge of DCD.
    UNASSIGNED: The objective of this study was to determine and describe intensive care nurses\' (ICNs\') knowledge, attitudes, and views on DCD before a national implementation in Sweden.
    UNASSIGNED: This study utilized a cross-sectional mixed-method design. A convenience sampling method was employed, targeting ICNs working in four intensive care units in Sweden. A study-specific tool comprising fixed and free-text questions was developed. Fifty-one ICNs participated. Data were analyzed descriptively, and correlation analysis was performed using Spearman\'s correlation. Free-text answers were qualitatively assessed and analyzed. An integrated analysis was conducted to synthesize the quantitative and qualitative findings.
    UNASSIGNED: Fifty-three percent reported limited knowledge about DCD. Nurses with previous education on DCD had significantly higher knowledge (r = .380, p = .006), were more engaged with the public debate on organ donation (r = .423, p = .002), and considered the ethical aspects of DCD more thoroughly (r = .386, p = .022). The qualitative analysis identified four key categories: The importance of the team, the need for ethical discussions, increased knowledge of DCD, and unanswered questions and unmet needs. The integrated analysis underscored the need for targeted education, clear guidelines, and ongoing ethical discussions to prepare ICU nurses for DCD.
    UNASSIGNED: Nurses educated in organ donor care had better knowledge and a more positive attitude toward DCD implementation. The study also highlights the importance of interprofessional teamwork in DCD implementation. The findings suggest that education on DCD could improve the identification and implementation of DCD donors, addressing the global shortage of transplantable organs.
