Abstract
Transplantation is an accepted therapeutic option to save or improve the quality of life when organ failure occurs or
tissue replacements are needed. However, the lack of organs is the major limitation. The deceased organ procurement
organization and professionals provide the solution to this international problem. In this review, we identify the elements
involved in the organ procurement management process to analyze the possibility of implementation of deceased organ
procurement for a transplantation program. While the donation rates are subject to several negative factors including
religious, economic, cultural, and legal issues, the existence of well-trained professionals may considerably increase them.
Professional training in organ donation along with the establishment of a solid organizational system has been identified
as the crucial factor in developing efficient organ donation and transplantation programs.

Introduction
The increase in the world’s population is the mainfactor to be considered by healthcare programs in thenear future. In 2008, the population was estimated to be6,500 million, and it is expected to rise to 9,000 millionby 2050, an increase of 50% in only 50 years.1 Thegroup with a higher quality of life is growing, thusworldwide life expectancy has risen to the current64.3 years.1 Society is changing, and social and health-care needs will consequently be affected in the comingyears. The patterns of disease differ depending on theage range of the population studied. With a mean ageof 60 years, consideration of chronic diseases generat-ing a higher demand on healthcare systems will be man-datory. Transplantation of organs and tissues will haveto increase in availability according to the new needs ofsociety. The main difference between transplantationand other medical therapies is that a donor programhas to be simultaneously implemented in a given coun-try, because ‘‘without donors there are no organs, andwithout organs there are no transplants’’.
Principles of organ transplantation
Some principles are mandatory. Organ transplantationmust be accepted as a successful and definitive therapy
for endstage organ failure by healthcare professionalsdirectly related to transplantation and also by political,business, and religious leaders. It is essential that thegovernment and healthcare authorities support thisbelief to give credibility to transplant and donation pro-fessionals. Transplantation must be considered a finan-cially effective and efficient therapy. Dedication offinancial resources to transplantation has to beaccepted as an added value to the medical system.Organ procurement must be recognized as an essential

component of the transplantation process. Investmentmust be allocated at a level equivalent to the act oftransplantation. The mainstay of success in a transplantprogram is maintaining the highest level of trust indonation. Integrity, honesty, and professionalism aremandatory to convey openness, sincerity, and transpar-ency in all policies, practices, and behavior of thehealthcare organization in charge of the donation andtransplantation programs.
Transplant Coordination
The first transplant coordination team in Spain wascreated in 1985 at the Hospital Clinic of theUniversity of Barcelona.2 Transplant coordination sub-sequently became a specific institutional departmentrequired for the development and growth of the insti-tution’s organ, tissue, and cell transplant programs.This model was introduced in other centers, regions,and countries.3 It was found that implementation oftransplant coordination departments with transplantprocurement management (TPM) specialists increasedthe activity of transplant programs, increasing thedonations for more wait-listed patients.4
Donors and Donations
Two types of donor can generate organs and tissues:deceased and living. Legal and ethical implicationsdiffer depending on the type of donation.5,6 A compar-ison of how a given country has developed and orga-nized a donation system shows clear differencesbetween continents regarding the distribution patternof deceased and living donors.7–9 As shown inFigure 1, European donations are predominantlybased on deceased donors, and Asian countries basi-cally focus on living donation. The USA has a mixedprogram; the rates of living and deceased donors aresimilar. There is consensus that the most importantproblem in transplantation is the scarcity of donors,and consequently, a shortage of organs for thenumber of potential recipients.5 All efforts in donationare focused on increasing the donation rate of eachcountry.8
The implications of the 2 types of donation are dif-ferent. Deceased donation is the only one allowingimportant structural changes in the global donationrates. Deceased donation is stable, transparent, lessaggressive, and better accepted by society. The struc-ture required to make possible a deceased donationmodel is complex and expensive, but where it is created,it permits a regulated and trusted donation and trans-plantation program. Furthermore, this structuredsystem facilitates the development of a living donation
program. This is due to the medical organization, thealready trained healthcare professionals, and an edu-cated population. Currently, most European countriesfocus on deceased donation and promote living dona-tion under a highly regulated and structured frameworkto avoid organ shortage.10 The key, under internationalagreement, is to create a strong deceased donation pro-gram. When this structure has been demonstrated to beefficient and trustworthy, a living donor program canbe developed.11
The essential step in donation and transplantation isto detect donors so as to obtain organs. The 2 types ofdonor include deceased donors, which can be after car-diac death or after brain death, and living donors(Figure 2). The most common multiorgan donors aredeceased after brain death. Brain death occurs when theintracranial pressure is higher than the blood pressure;then, there is no blood flow to the brain (Figure 3).12
The diagnosis of brain death has to be carried out veryaccurately following specific clinical examinations, andconfirmed by instrument tests (Table 1).13 There arealso deceased donors after cardiac death.14 Diagnosisof death is performed according to cardiorespiratorycriteria (irreversible cardiac arrest). Organs are affectedby a period of warm ischemia. These donors can bedivided into 2 main groups: uncontrolled deceasedafter cardiac death (Maastricht categories I-II), whenunexpected cardiac arrest occurs, or controlleddeceased after cardiac death (Maastricht categoriesIII-IV), also known as awaiting cardiac arrest.Considering donors deceased after cardiac death,fewer organs (mainly kidneys and livers) can be consid-ered for transplantation compared to those deceasedafter brain death. In the case of living donors, usuallyonly kidneys and liver are considered. Ethically, thereare more questions, and the balance of risks to benefitsis not as clear as with cadaveric donors.15 Furthermore,the protection of the donor has to be assured by thehealthcare system.10
Essential Elements in Developing aTransplant Procurement ManagementModel
To perform a global analysis of the implemention of anorgan and tissue donation and transplantation systemin a region or country, it is necessary to take intoaccount each of the essential elements, known as thestars of TPM (Figure 4).16 Society and social attitudesare the foundations of the system. Not taking societyinto consideration would make the creation of a posi-tive attitude towards donation impossible. Unlikeother medical practices, transplantation activity doesnot depend only on technical, surgical, and

pharmacological aspects, but also on the altruistic andfree donation of members of society. Therefore, organtransplantation requires both skilled medical expertiseand high levels of trust, support, and participation fromthe general public. Without the willingness of membersof society to donate, transplantation cannot beconsidered.
Society’s attitude towards donation is directlyrelated to the economic development and welfare ofthe population, the percentage of gross national prod-uct invested in health, and the type of healthcare systemsupported by the government. Furthermore, history,religion and cultural relationships with the concept ofdeath are factors influencing society’s positive attitude,and consequently, the rates of organ and tissue dona-tion. Society also closes the cycle by evaluating theentire process. The population should be aware of thequality of life of transplant patients, the results of trans-plant programs, and the graft and patient survivalrates. Without this feedback, society could hardlybuild an opinion about the process.
Education
Initially, a key factor in the success of donation andtransplantation processes is the motivation, trust, andpositive attitude of healthcare professionals includingphysicians, nurses, and paramedics working in hospi-tals with potential donors. This positive attitude is pos-sible thanks to the education of these professionals.17
The process of obtaining organs and tissues entails aseries of procedures and skills that are fundamental toraise the number and quality of transplants.Professionals involved in transplant coordinationrequire solid and comprehensive training, essential tointegrate donation and transplantation processes in theclinical field.
Education does not have to be focused only onhealthcare professionals directly related to donationand transplantation. It is essential that the wholehealthcare body receives clear scientific informationand learns the skills for diagnosis of brain death, thephysiology and treatment of the organs of a deadpatient, and the legal and ethical aspects of donation.

Priority given to the education of healthcare profes-sionals will facilitate the entire donation and transplan-tation process because they can teach the general publicand other allied professionals.18
On a second level, the next step should be to educatethe general population. Public educational programsshould take into account the fact that their maingoals are to give information about the essentials ofthe process in an easy and clear manner and toanswer basic questions such as who can donate, whatcan be donated, when and where somebody can becomea donor, and for which diseases organ and tissue
transplantation is indicated. Such programs shouldalso explain that organ and tissue transplantation is anecessary and accepted part of medical care. The tar-gets of an educational program should be the key mem-bers of society, especially young people.18 Adults can bereached either directly or through their children.University students are a target to consider as theywill become the future professionals.
Mass media have an enormous impact on the pop-ulation, but the cost of campaigning is usually very highand the cost-effectiveness is low. It is most important totransmit positive news about donation and inform

society about transplantation success. Meetings andpublic campaigns to explain the essentials of donation,using different groups such as social or cultural associ-ations, opinion or religious groups, are highly recom-mended. All efforts invested in education should aim atobtaining a long-lasting impact on society.
Healthcare System
Depending on the type of healthcare system, the TPMwill be conceived differently. Society’s opinion aboutthis system has an essential impact on the attitudetowards donation. One of the keys to the success ofthe Spanish system of donation of organs and tissuesis the trust of the Spanish population in its universalhealthcare system. Because everybody has the samechance of receiving a transplant, the act of donationis easily accepted.19,20 The establishment of a donationand transplantation program entails a new goal for
healthcare professionals. When a patient is declaredbrain dead or presents with cardiorespiratoty arrest,the hospital’s new goal consists of generating organs,tissues, and cells to save or improve the quality of life ofothers.21,22
National Economy
Population welfare is directly related to the economy ofa country or region. Stable economic support to start atransplant program is essential because it representshigh human, material, and financial costs. Resourcemanagement is one of the responsibilities of the TPM.All resources necessary to generate a donor, organ, andtissue, determine the cost that should be known andnegotiated. The TPM must know which resources areneeded for the mission and how to get them. Therefore,planning and negotiation are absolutely requiredskills.23–25

New Vital Cycle
Transplantation is possible thanks to a new vital cycleenabling a society that donates and has transplant coor-dination to benefit from the process (Figure 5). Society,thanks to a positive attitude that depends on cultural,religious, economic, and educational factors, donates
according to an altruistic process. Donation is the pro-cess that converts society’s will into the procurement oforgans, tissues, and cells. The TPM is in charge of thisprocess.26,27 Consequently, it is possible thanks todonor detection, the people responsible for this process,authorized centers, regulatory provisions, trained organand tissue retrieval teams, and the organizational workperformed by TPM departments. The organ sharingand allocation system must be organized to ensure themost ethical and fairest procedures, making the best useof the available organs, and increasing patients’ trans-plantation possibilities.11 The process involves waitinglist management systems and distribution criteria basedon consensus. Once the organ has been allocated, trans-plants can be performed, and the recipients monitoredin authorized centers. These centers organize thefollow-up of recipients and living donors. Resourcesand procedures to promote good graft survival aswell as measures to treat complications are mandatory.The creation of national and international registries iscritical to normalize the activity developed in the coun-try.8 Registries offer the opportunity to promote resultsand experiences among professionals, institutions, andsociety. The positive attitude of society will be empow-ered through well-planned mass media campaigning.
Transplant Procurement Management
The success of a transplant program lies in profession-alizing donation and sharing responsibilities.28,29

for tissues. The TPM specialist must analyse the possi-bilities of facilitating transplants, to coordinate allaspects that make it possible. The TPM oversees poten-tial donors in a situation of brain death or cardiorespira-tory arrest and also dead patients for donation. A TPMspecialist should be a professional aged 30–40 years, maleor female, a specialized physician, working with otherexperienced physicians or nurses for whom donation is agoal and not a step on the road to other objectives. Theyneed to be skilled in personal and professional relation-ships to be locally accepted and acknowledged, supportedby hospital managers, and paid for their work. The pro-fessionalism of donor-transplant coordinators must beachieved with suitable training.
The TPM is a strategic international approach tocombat organ and tissue shortages. The main goal ofthe TPM is to increase the quantity, quality, and effec-tiveness of organ and tissue donation by training andadvising healthcare professionals in the major steps ofthe donation process: detection and evaluation ofpotential organ and tissue donors, brain death diagno-sis, donor maintenance, family approach for organdonation, organ retrieval and allocation, tissue pro-curement, processing storage and clinical applications,and quality assurance of the entire process. Our TPMproject was launched in 1991 under the auspices of theUniversity of Barcelona and with technical and finan-cial support from the Spanish National OrganTransplantation Organization, as a specialized profes-sional training program. From 2007 to 2010, theInstitute for LifeLong Learning, and from 2010onwards, the Barcelona Scientific Park has beeninvolved in postgraduate programs at the Universityof Barcelona, offering master’s degrees, postgraduatediplomas, and specialization certificates. The TPMextended its educational activities to 7,200 participantsfrom 93 countries by the end of 2009 in face-to-face,
on-line, and blended-learning modalities. In 1994, itwas recognized by the Transplant Committee of theEuropean Council. The TPM acquired an internationaldimension soon after its start. To make this possible,and throughout the years, the TPM has created its owncorporate image, course design and contents, produceda wide range of teaching material, and created its ownsoftware. Special attention is given to adapt the coursesto the specific needs of different countries: advancedcourses are implemented yearly in 4 languages(Spanish, English, Italian, and French), and face-to-face specific training sessions are developed on requestin local languages, by translating the educational mate-rial and interpreting the faculty lectures. Moreover, theTPM represents an official transplant coordinationtraining program of Agence de la Biomedecine(France) and Centro Nazionale Trapianti (Italy). TheTPM works closely with partner organizations toinclude local experts in the curriculum. Currently, ithas a vast network of qualified professionals through-out the world, maximizing the impact of the work ineach country. This network has allowed the TPM toengage health professionals in international projectsto analyze and improve the quality and safety associ-ated with organ, tissue, and cell donation and trans-plantation among European countries. The TPM hasrecently coordinated a 3-year European CommissionHealth and Consumer Policy project: the EuropeanTraining Program on Organ Donation.
Procurement
The most important step in improving the results of atransplant program is to focus on donation. The com-position of the team in charge has changed over theyears in different countries. Figure 6 shows 3 modelsof procurement organization location regarding the

hospital. The pioneer model is the one in which hospitaltransplant teams are in charge of procurement manage-ment in addition to their normal activity of transplan-tation. Ethical aspects can also be discussed. It is themost commonly used model at the beginning of theimplementation of a TPM organization. In othermodels, the procurement organization depends onexternal organizations (in another building far fromthe hospital) as is the case with American organ pro-curement organizations, where some of the personnelmust be assigned to the promotion of donor detection.This model fits vast geographic areas because it allowsthe control of more than one center, but it has to besupported by strong campaigns to make sure braindead patients are reported as potential donors, avoid-ing donor loss.
The system known as the Spanish model considersthat the TPM specialist is in charge of the donation oforgans and tissues and acts as a particular service of thehospital.4 Because such specialists work for and providea service to everyone, they must be staff members andhierarchically under the responsibility of the medicaldirector so as to maintain their independence withinthe hospital. Experience has shown that there is no per-fect model, and each country has to adapt the procure-ment organization to its own reality, taking intoaccount the healthcare system, the hospitals, and theextension of the concerned areas.11
Sharing
Distribution and exchange of organs must be well orga-nized in order to allocate them as ethically and legallyas possible, facilitating a policy of exchanges, maximis-ing the procured organ’s benefit and the transplantrecipient’s chances. An organ allocation system impliesmore management standards in waiting list coordina-tion and more consensus-based distribution criteria.
Each transplant system has to define who is responsiblefor donor detection and transplantation. This task usu-ally lies within the hospital. The national or regionalorganization has to organize and manage the transplantnetwork, collaborating with donation promotion andeducation. As an example, in Spain, the NationalOrgan Transplantation Organization arranges the pro-cess between donors and recipients based on criteriaestablished by healthcare professionals. The SpanishNational Organ Transplantation Organization isresponsible for editing consensus documents, partici-pating in international quality meetings, and promotingpolicies aimed at benefiting transplantation through anational discussion forum (interregional council).Organ donation and distribution is the responsibilityof the health administration, which should be obligedto provide the necessary resources and guarantee thefairness, transparency, and safety of the entire system.
Transplantation
Transplantation must be lead by experts and well-trained transplant teams, with human, material, andfinancial resources dedicated to transplantation. Thetransplantation has to be carried out and the recipientfollowed up in these specialist centers, with experience,resources, and authorisation, demonstrating good graftsurvival rates. Patients have to be monitored in a well-organised fashion, immunosuppressive drugs must beavailable, and the team must be able to treatcomplications.
Payment
Providing adequate financial resources is critical toensure the normal functioning of donation and trans-plantation organization. A solid budget must begranted to pay for staff, equipment, administrative

facilities, and the educational activities of the program.Financial costs for donor recovery and associatedtesting should also be considered for payment. TheTPM payment system should be mixed, with a fixedpart for a day’s work, equivalent to other specialistsof the center, and a variable part according to activity.Depending on the department capacity to generatedonors, the TPM contract should be considered afull-time job.16
Quality
The TPM should always strive to establish all necessarymechanisms to ensure quality in all steps of the dona-tion and transplantation process. To this end, the TPMshould establish appropriate standard operating proce-dures, develop a registry of all activity performed, keepa complete clinical donor record including all requireddocuments and legal procedures, and follow-up alldonor viability studies and laboratory results thatcould affect the quality of the organ and/or tissue trans-planted. Furthermore, it is advisable to implementsome of the internationally recognized quality controlsystems for each process, and in the future, secureaccreditation for transplant coordination units andthe TPM through national and international officiallyapproved societies, organizations, or universities, toachieve better performance and quality. The donationand transplantation process is lengthy and complex; itrequires continuous assessment to detect where, when,and why donors are lost, and attempt to define the bestpossible solutions. It is necessary to identify the areas inwhich efforts should be directed. Improvement is thesingle objective of this assessment process.
It is of great interest to participate in national andinternational registries for the purpose of comparingresults and experiences, such as quality control of theprograms.8,10 The record of these values ensures thetraceability and transparency of the activity. A registryhas, therefore, become a mandatory requirement forthe TPM in a hospital at regional, national, and inter-national levels. There are various registries according tothe factors to be analyzed. The hospital registry allowsthe control of each donation and transplantation casewithin the hospital area; it is a compulsory part of theorgan and tissue procurement coordination. Thenational registry normalizes the activity developed inthe country by promoting its evaluation and thedesign of new strategies to improve the results. Theinternational registry is a consultation tool allowingcomparison of the activity in different countries.There are several active international registries compil-ing donation and transplantation activity according todifferent variables.1,7 All registries offer the opportunity
to promote their results and experiences of donationand transplantation activity.
Finally, quality must be assured from the outset ofimplementation of the donation and transplantationsystem in a country or region. Initial advice and furtheranalysis of the results are mandatory to ensure ade-quate development of the process. Several institutions,such as the Donation and Transplantation Institute(www.dtifoundation.org), have been effective in givingsupport to developing programs.
Research and Development
The aim of the research and development of a TPMspecialist is to increase the quality and number oforgans and tissues for transplantation. Donor detectionsystem improvement is another field to analyse anddevelop, including measurement of donation potential-ity, control of the efficiency of the process, and theusage rate of generated organs. Donor maintenance,brain death diagnosis, organ perfusion, non-beatingheart donation, ischemia-reperfusion, and transplantpreconditioning are important study topics. Workingon the use of expanded-criteria donors opens new pos-sibilities for donation, including the use of organs fromC virus antibody-positive donors, elderly hepaticdonors, hepatic and cardiac domino donors for tissues,double renal transplants, partial hepatic transplantsfrom living donors, combined transplants from differ-ent organs, and adult-pediatric transplants. Moreover,human tissues are also of interest for study. There arestudies on cell viability, sterilization, bioengineering,and cryobiology. The TPM can also participate in gen-erating tissues and cells for research, such as pancreaticislets, hepatocyte islets for implants or a hepatic biore-actor, olfactory ganglia, vascular tissue for culture, andcardiac tissue for functionalism among others.
Conclusions
Organ and tissue donation and transplantation repre-sents a social good that must be protected and pro-moted, from the administration to the healthprofessionals. Society must be deeply involved. Thereare several elements that can influence attitudestowards organ donation. Legislation, financial support,specialized training for health professionals, and cul-tural acceptance of the process are key issues in thesuccess of an organ procurement program.19,20 Thefirst step is education of the health professionals whowill spread their positive attitude and knowledge oforgan donation to the population.17,18 Secondly, it isconvenient to start with a deceased donor system as it iseasier to ensure transparency and establish a larger andstronger structure. After efficient implementation of a

deceased donor organization (after brain death andafter cardiac death), the extension to living donationwill be easier. Living donation has to be a secondoption after brain death and cardiac death, becauseliving donors restrict procurement to fewer organs perdonor and require more organization than deceaseddonation.10 It is essential to be well trained and advisedbefore implementing any system, to make sure that theprocess will be clear, transparent, and fair, in order toguarantee quality.
