Prácticas clínicas al final de la vida en pacientes con daño cerebral catastrófico en España: implicaciones para la donación de órganos

Organ Donation Organization Architecture: Recommendations From an International Consensus Forum

This report contains recommendations from 1 of 7 domains of the International Donation and Transplantation Legislative and Policy Forum (the Forum). The purpose is to provide expert guidance on the structure and function of Organ and Tissue Donation and Transplantation (OTDT) systems. The intended audience is OTDT stakeholders working to establish or improve existing systems.

Methods

The Forum was initiated by Transplant Québec and co-hosted by the Canadian Donation and Transplantation Program partnered with multiple national and international donation and transplantation organizations. This domain group included administrative, clinical, and academic experts in OTDT systems and 3 patient, family, and donor partners. We identified topic areas and recommendations through consensus, using the nominal group technique. Selected topics were informed by narrative literature reviews and vetted by the Forum's scientific committee. We presented these recommendations publicly, with delegate feedback being incorporated into the final report.

Results

This report has 33 recommendations grouped into 10 topic areas. Topic areas include the need for public and professional education, processes to assure timely referral of patients who are potential donors, and processes to ensure that standards are properly enforced.

Conclusions

The recommendations encompass the multiple roles organ donation organizations play in the donation and transplantation process. We recognize the diversity of local conditions but believe that they could be adapted and applied by organ donation organizations across the world to accomplish their fundamental objectives of assuring that everyone who desires to become an organ donor is given that opportunity in a safe, equitable, and transparent manner.

Comparing demographics of organ donor referrals from the Intensive Care Unit and Outside Units

BACKGROUND

The Spanish organ donation system is a world leader in organ recovery. One of Spain's strategies is identification of organ donor referrals outside of the intensive care unit (ICU) for intensive care to facilitate organ donation (ICOD). There is limited data comparing the profiles of ICU-based and non-ICU ICOD referrals.

METHODS

This single-center retrospective chart review analyzed organ donor referrals of ICU and non-ICU patients to better understand the demographic and clinical differences between cohorts. The primary outcome was to understand if organ donation conversion rates were similar between ICU and non-ICU referrals.

RESULTS

We collected data from 745 organ donor referral candidates, 235 (32%) of whom entered ICOD protocols. Out of this cohort, 144 (61%) became an actual organ donor, 37 of whom (26%) were referred from non-ICU units. The ICU had the highest organ donor conversion rate (66% of ICU ICOD patients became actual organ donors) whereas non-ICU referrals had a 51% conversion rate. Non-ICU unit donors contributed to 21% and 26% of all kidney and liver donations, respectively.

CONCLUSION

Though organ referral candidates from non-ICU units contribute to a small proportion of actual donors, their donated organs are important to sustaining organ donation and transplant activity.

Organ donation and transplantation: a multi-stakeholder call to action

Although overall donation and transplantation activity is higher in Europe than on other continents, differences between European countries in almost every aspect of transplantation activity (for example, in the number of transplantations, the number of people with a functioning graft, in rates of living versus deceased donation, and in the use of expanded criteria donors) suggest that there is ample room for improvement. Herein we review the policy and clinical measures that should be considered to increase access to transplantation and improve post-transplantation outcomes. This Roadmap, generated by a group of major European stakeholders collaborating within a Thematic Network, presents an outline of the challenges to increasing transplantation rates and proposes 12 key areas along with specific measures that should be considered to promote transplantation. This framework can be adopted by countries and institutions that are interested in advancing transplantation, both within and outside the European Union. Within this framework, a priority ranking of initiatives is suggested that could serve as the basis for a new European Union Action Plan on Organ Donation and Transplantation.

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.

Deceased donor care provided by the nurse transplant coordinator: A qualitative research study among Spanish nurses

AIM

The purpose of this study is to describe the experience of nursing care provided to the deceased organ donor by the nurse transplant coordinator.

METHODS

A qualitative exploratory study was conducted within the National Transplant Organization and the Regional Office for Transplant Coordination. A purposive sampling method was used. Data collection methods included semistructured interviews. Sampling and data collection were pursued until the researchers achieved information redundancy. A systematic text condensation analysis was performed. The Guba and Lincoln criteria for guaranteeing trustworthiness were followed.

RESULTS

A total of 16 participants were recruited, and three themes were identified regarding care of organ donors by the nurse transplant coordinator during the organ donation process: (a) fulfilling the desire and will of the donor patient; (b) the family as an extension of the donor; (c) coordinating the organ donation process.

CONCLUSIONS

The donation process is both complex and delicate, and nursing care is an essential component. The care provided by the nurse transplant coordinator has the donor at the centre of the process, driven by respect for their decision. The family is seen as an extension of the donor. Nursing care should focus on continuous, honest communication, coordinating care with the intensive care unit, ensuring privacy and intimacy.

Facilitators and Barriers in the Organ Donation Process: A Qualitative Study among Nurse Transplant Coordinators

Background: Spain is the world leader in organ donation, with a rate of 49.0 donations per million population. Nurse transplant coordinators fulfill key roles for the success of the complex donation process. Our aims were: (a) to describe the experience of nurse transplant coordinators and (b) to identify barriers and facilitators during the process of organ donation. Methods: A qualitative phenomenological study was conducted within the National Transplant Organization. A purposive sampling method was used, and data collection methods included semistructured interviews, researcher field notes, and participants’ personal letters. A systematic text condensation analysis was performed. The study was approved by the Clinical Research Ethics Committee. Results: A total of 16 participants were recruited and four themes were identified: (a) a different job for nurses, (b) facilitators and barriers of the coordinator’s job, (c) not a job for a novice nurse, and (d) coordinators facing a paradigm shift. Coordinators described their job as being characterized with uncertainty and having to face emotional and institutional barriers. The facilitators identified were high educational level and training, and feelings of pride for being part of the National Transplant Organization. Conclusions: The organ donation process requires specialized training to avoid organizational barriers.

Online education about end-of-life care and the donation process after brain death and circulatory death. Can we influence perception and attitudes in critical care doctors? A prospective study

Impact of training on end-of-life care (EOLC) and the deceased donation process in critical care physicians' perceptions and attitudes was analysed. A survey on attitudes and perceptions of deceased donation as part of the EOLC process was delivered to 535 physicians working in critical care before and after completion of a online training programme (2015-17). After training, more participants agreed that nursing staff should be involved in the end-of-life decision process (P < 0.001) and that relatives should not be responsible for medical decisions (P < 0.001). Postcourse, more participants considered 'withdrawal/withholding' as similar actions (P < 0.001); deemed appropriate the use of pre-emptive sedation in all patients undergoing life support treatment adequacy (LSTA; P < 0.001); and were favourable to approaching family about donation upon LSTA agreement, as well as admitting them in the intensive care unit (P < 0.001) to allow the possibility of donation. Education increased the number of participants prone to initiate measures to preserve the organs for donation before the declaration of death in patients undergoing LSTA (P < 0.001). Training increased number of positive terms selected by participants to describe donation after brain and circulatory death. Training programmes may be useful to improve physicians' perception and attitude about including donation as part of the patient's EOLC.

The Implementation of a Multidisciplinary Approach for Potential Organ Donors in the Emergency Department

BACKGROUND

The aim of this study was to evaluate the implementation process of a multidisciplinary approach for potential organ donors in the emergency department (ED) in order to incorporate organ donation into their end-of-life care plans.

METHODS

A new multidisciplinary approach was implemented in 6 hospitals in The Netherlands between January 2016 and January 2018. The approach was introduced during staff meetings in the ED, intensive care unit (ICU), and neurology department. When patients with a devastating brain injury had a futile prognosis in the ED, without contraindications for organ donation, an ICU admission was considered. Every ICU admission to incorporate organ donation into end-of-life care was systematically evaluated with the involved physicians using a standardized questionnaire.

RESULTS

In total, 55 potential organ donors were admitted to the ICU to incorporate organ donation into end-of-life care. Twenty-seven families consented to donation and 20 successful organ donations were performed. Twenty-nine percent of the total pool of organ donors in these hospitals were admitted to the ICU for organ donation.

CONCLUSIONS

Patients with a devastating brain injury and futile medical prognosis in the ED are an important proportion of the total number of donors. The implementation of a multidisciplinary approach is feasible and could lead to better identification of potential donors in the ED.

Missed opportunities for organ donation in patients with intracranial haemorrhage at the emergency department: A single-centre study

Background:

The demand for transplantable organs has increased in Singapore. However, organ donation has been consistently lower than international standards. Donation after brain death (DBD) most commonly follows intracranial haemorrhage (ICH).

Objective:

Our aim was to identify missed opportunities for organ donation among those who presented to the Emergency Department (ED) and died following ICH.

Methods:

A retrospective study was carried out for all cases of ICH presenting to the ED from 1 January 2013 to 31 December 2017. The patients’ medical records were reviewed for identification of potential donors and actualisation of organ donation.

Results:

There were 615 cases of ICH, with a mortality rate of 6.0%. Among those who died, 28 (75.7%) died in the Intensive Care Unit (ICU) and nine (24.3%) patients had withdrawal of care in the ED. Thirty patients (81.1%) were potential donors but organ donation was actualised in only three (8.1%) patients. Thirteen organs, as well as heart valves and iliac vessels were retrieved from the organ donors for transplantation.

Conclusion:

There were missed opportunities for organ donation. EDs have an important role to play in the national organ donation programme by identifying potential donors for organ donation and considering admitting these patients to ICU to facilitate organ donation.

Criteria to Identify a Potential Deceased Organ Donor: A Systematic Review

OBJECTIVES

To systematically review the global published literature defining a potential deceased organ donor and identifying clinical triggers for deceased organ donation identification and referral.

DATA SOURCES

Medline and Embase databases from January 2006 to September 2017.

STUDY SELECTION

All published studies containing a definition of a potential deceased organ donor and/or clinical triggers for referring a potential deceased organ donor were eligible for inclusion. Dual, independent screening was conducted of 3,857 citations.

DATA EXTRACTION

Data extraction was completed by one team member and verified by a second team member. Thematic content analysis was used to identify clinical criteria for potential deceased organ donation identification from the published definitions and clinical triggers.

DATA SYNTHESIS

One hundred twenty-four articles were included in the review. Criteria fell into four categories: Neurological, Medical Decision, Cardiorespiratory, and Administrative. Distinct and globally consistent sets of clinical criteria by type of deceased organ donation (neurologic death determination, controlled donation after circulatory determination of death, and uncontrolled donation after circulatory determination of death) are reported.

CONCLUSIONS

Use of the clinical criteria sets reported will reduce ambiguity associated with the deceased organ donor identification and the subsequent referral process, potentially reducing the number of missed donors and saving lives globally through increased transplantation.

Summary of Spanish recommendations on intensive care to facilitate organ donation

With the aim of consolidating recommendations about the practice of initiating or continuing intensive care to facilitate organ donation (ICOD), an ad hoc working group was established, comprising 10 intensivists designated by the Spanish Society of Intensive Care and Coronary Units (SEMICYUC) and the Spanish National Transplant Organization (ONT). Consensus was reached in all recommendations through a deliberative process. After a public consultation, the final recommendations were institutionally adopted by SEMICYUC, ONT, and the Transplant Committee of the National Health-Care System. This article reports on the resulting recommendations on ICOD for patients with a devastating brain injury for whom the decision has been made not to apply any medical or surgical treatment with a curative purpose on the grounds of futility. Emphasis is made on the systematic referral of these patients to donor coordinators, the proper assessment of the likelihood of brain death and medical suitability, and on transparency in communication with the patient's family. The legal and ethical aspects of ICOD are addressed. ICOD is considered a legitimate practice that offers more patients the opportunity of donating their organs upon their death and helps to increase the availability of organs for transplantation.

Outcomes of very elderly trauma ICU patients. Results from the Spanish trauma ICU registry

OBJECTIVE

To analyze outcomes and factors related to mortality among very elderly trauma patients admitted to intensive care units (ICUs) participating in the Spanish trauma ICU registry.

DESIGN

A multicenter nationwide registry. Retrospective analysis. November 2012-May 2017.

SETTING

Participating ICUs.

PATIENTS

Trauma patients aged ≥80 years.

INTERVENTIONS

None.

MAIN VARIABLES OF INTEREST

The outcomes and influence of limitation of life sustaining therapy (LLST) were analyzed. Comparisons were established using the Wilcoxon test, Chi-squared test or Fisher's exact test as appropriate. Multiple logistic regression analysis was performed to analyze variables related to mortality. A p-value <0.05 was considered statistically significant.

RESULTS

The mean patient age was 83.4±3.3 years; 281 males (60.4%). Low-energy falls were the mechanisms of injury in 256 patients (55.1%). The mean ISS was 20.5±11.1, with a mean ICU stay of 7.45±9.9 days. The probability of survival based on the TRISS methodology was 69.8±29.7%. The ICU mortality rate was 15.5%, with an in-hospital mortality rate of 19.2%. The main cause of mortality was intracranial hypertension (42.7%). The ISS, the need for first- and second-tier measures to control intracranial pressure, and being admitted to the ICU for organ donation were independent mortality predictors. LLST was applied in 128 patients (27.9%). Patients who received LLST were older, with more severe trauma, and with more severe brain injury.

CONCLUSIONS

Very elderly trauma ICU patients presented mortality rates lower than predicted on the basis of the severity of injury.

Donation after circulatory death and its expansion in Spain

PURPOSE OF REVIEW

Donation after circulatory death (DCD) is still performed in a limited number of countries. This article summarizes the development of DCD in Spain and presents recent Spanish contributions to gain knowledge on the potential benefits and the practical use of normothermic regional perfusion (nRP).

RECENT FINDINGS

DCD now contributes to 24% of deceased donors in Spain. The development of DCD has been based on an assessment of practices in the treatment of cardiac arrest and end-of-life care to accommodate the option of DCD; the creation of an adequate regulatory framework; and institutional support, professional training and public education. Appropriate posttransplant outcomes have been obtained with organs from both uncontrolled and controlled DCD donors. nRP is increasingly used, with preliminary data supporting improved results compared with other in-situ preservation/recovery approaches. Mobile teams with portable extracorporeal membrane oxygenation devices are making nRP possible in hospitals without these resources. To avoid the possibility of reestablishing brain circulation after the determination of death, a specific methodology has been validated.

SUMMARY

DCD has been successfully developed in Spain following a streamlined process. nRP may become a standard in DCD, although further evidence on the benefits of this technology is eagerly awaited.

Examination of the Brain-Dead Organ Donor Management Process at a Spanish Hospital

The number of donors and organs available has not increased at the same rate as the inclusion of new patients in the waiting lists. The aim of the present study was to analyze the quality of the detection process of potential brain-dead organ donors at the Hospital of León. For this, a cross-sectional prospective study was developed on a retrospective cohort of patients who were admitted or died by catastrophic brain damage with the potential for organs donation. Data were collected for six months using hospital records of admissions and exitus. For the statistical analysis, the free distribution software Epi Info 3.5.4 was employed. A total of 627 patients were studied: 550 were discharged and 77 died as potential donors. Of the potential donors, 65 died in asystole, but 60 of them had an absolute contraindication to donation and 20 died after limitation of life support therapy. Five cases with donor criteria in controlled asystole were detected. The analysis found that the detection process conformed to the regulatory framework stablished by the National Transplant Organization. However, population aging leads to a high rate of absolute contraindications among detected potential donors. The donation capacity of the hospital could therefore be increased with the implementation of a donor protocol in controlled asystole.

"Do not do" recommendations of the working groups of the Spanish Society of Intensive and Critical Care Medicine and Coronary Units (SEMICYUC) for the management of critically ill patients

The project "Commitment to Quality of Scientific Societies", promoted since 2013 by the Spanish Ministry of Health, seeks to reduce unnecessary health interventions that have not proven effective, have little or doubtful effectiveness, or are not cost-effective. The objective is to establish the "do not do" recommendations for the management of critically ill patients. A panel of experts from the 13 working groups (WGs) of the Spanish Society of Intensive and Critical Care Medicine and Coronary Units (SEMICYUC) was selected and nominated by virtue of clinical expertise and/or scientific experience to carry out the recommendations. Available scientific literature in the management of adult critically ill patients from 2000 to 2017 was extracted. The clinical evidence was discussed and summarized by the experts in the course of consensus finding of each WG, and was finally approved by the WGs after an extensive internal review process carried out during the first semester of 2017. A total of 65 recommendations were developed, of which 5 corresponded to each of the 13 WGs. These recommendations are based on the opinion of experts and scientific knowledge, and aim to reduce those treatments or procedures that do not add value to the care process; avoid the exposure of critical patients to potential risks; and improve the adequacy of health resources.

How Spain Reached 40 Deceased Organ Donors per Million Population

With 40 donors and more than 100 transplant procedures per million population in 2015, Spain holds a privileged position worldwide in providing transplant services to its patient population. The Spanish success derives from a specific organizational approach to ensure the systematic identification of opportunities for organ donation and their transition to actual donation and to promote public support for the donation of organs after death. The Spanish results are to be highlighted in the context of the dramatic decline in the incidence of brain death and the changes in end-of-life care practices in the country since the beginning of the century. This prompted the system to conceive the 40 donors per million population plan, with three specific objectives: (i) promoting the identification and early referral of possible organ donors from outside of the intensive care unit to consider elective non-therapeutic intensive care and incorporate the option of organ donation into end-of-life care; (ii) facilitating the use of organs from expanded criteria and non-standard risk donors; and (iii) developing the framework for the practice of donation after circulatory death. This article describes the actions undertaken and their impact on donation and transplantation activities.
