Organ donation is the generous act of offering an organ or a portion of it for transplantation into another individual. It serves as the sole lifeline for patients grappling with terminal organ failures, promising not only survival but an improved quality of life. However, a significant gap persists between the supply of donated organs and the soaring demand, resulting in the unfortunate loss of countless lives.

Over the last two decades, the number of organ transplantations has steadily increased, delivering remarkable outcomes, particularly for children and young adults. Nevertheless, the landscape is evolving as the proportion of elderly transplant patients with multiple health issues grows, posing new challenges.

The ongoing improvements in organ transplantation outcomes are a testament to continuous innovations and enhanced peri-operative management. However, the critical factor in organ transplantation remains the availability of human organs. Scarcity prevails, resulting in extensive waiting lists, with approximately 63,000 individuals in the European Union and over 100,000 in the United States seeking transplantation.

The process of organ procurement and transplantation heavily relies on healthcare resources and the performance of healthcare professionals in identifying potential donors and managing the donation process. Yet, crucially, it is predominantly influenced by personal or familial decisions, profoundly shaped by psychosocial factors, as dictated by existing legislation.

Organ Transplantation and Donation:

Organ transplantation represents a medical marvel involving the surgical transplantation of an organ or a portion of it into an individual suffering from organ failure. This life-saving procedure can utilize organs from both deceased and living donors. However, it encompasses more than just the surgical aspect; it involves a profound evaluation of the patient’s psychological, behavioral, emotional, and mental health before and after transplantation. For living donors, especially in cases like kidney and liver segment transplantation, their psychological response to organ donation is a pivotal consideration in the transplantation process.

The Crucial Act of Organ Donation Organ donation is the act of selflessly giving an organ or part of it to be transplanted into another person. This altruistic act carries the potential to save lives, with a single donor capable of impacting up to eight lives. Organ transplantation often becomes the last hope for individuals facing life-threatening conditions. Unfortunately, a considerable gap exists between the supply and demand of donated organs, resulting in the tragic loss of numerous lives.

Health Challenges and the Need for Transplantation Certain populations, such as Asian Indians, face a higher risk of conditions like obesity and diabetes compared to other groups. These health issues increase the likelihood of requiring a donated organ. Conditions like diabetes and obesity can lead to complications such as coronary artery disease, hypertension, and chronic kidney disease, necessitating regular dialysis and potentially leading to organ transplantation for an improved quality of life. Moreover, these conditions can also result in fatty liver disease, which may progress to chronic liver disease and the need for liver transplantation.

The Evolution of Organ Transplantation The development of organ transplantation in the latter half of the 20th century stands as a remarkable achievement in the field of medicine. Today, it ranks among the most effective options for individuals with end-stage organ failure. Its success hinges on factors like public awareness, support, and active participation. Without these elements, the effectiveness of organ transplantation and the consequent extension or saving of lives would have faced significant challenges.

The demand for organ transplantation has surged, but the supply of available organs has seen only marginal growth. Factors like expanded donor selection criteria and improvements in safety measures have impacted the donor pool. While public education campaigns have encouraged organ donation, many donors on paper may never actually become organ donors due to various circumstances.

The Role of Living Donors To address the growing demand for transplantation, some transplant programs are exploring ways to increase the number of transplants from living donors. While living donation has always been an option for specific types of transplants, concerns regarding the invasive surgery required on healthy donors have limited its promotion. Nonetheless, as the need for organs continues to rise, the medical community is considering living donation as a viable solution, despite the associated risks and ethical considerations.

Varieties of Organ Donation and Donors:

Types of Organ Donation

1. Autograft

• Autograft involves the transplantation of an individual’s tissues from one part of their body to another. For example, skin from the legs may be transplanted to repair damaged facial or exposed skin.

2. Allograft

• Allograft refers to the transplantation of an organ between two genetically non-identical individuals. Due to genetic differences, the recipient’s immune system may perceive the donor organ as foreign and initiate rejection.

3. Isograft

• Isograft involves the transplantation of an organ or tissue from a genetically identical donor to the recipient. Since there is genetic compatibility, there is typically no immune response, leading to minimal risk of rejection.

4. Xenograft

• Xenograft entails the transplantation of organs or tissues from one species to another. An example includes the successful transplantation of a pig’s heart valve into a human.

5. Split Transplant

• In a split transplant, an organ, often a liver, obtained from a deceased donor, is divided between two recipients, typically an adult and a child.

6. Domino Transplant

• Domino transplant occurs when the lungs are to be transplanted. Surgically, it is more feasible to replace both the lungs and the heart together. If the recipient’s original heart is healthy, it can be transplanted into another recipient in need.

7. ABO Incompatible Transplantation

• Young children under 12 months of age may have an underdeveloped immune system, allowing them to receive organs from donors who are ABO incompatible.

Types of Donors:

1. Live Donors

• Live donors are mentally and physically healthy individuals who can donate a paired organ, part of an organ, or tissue while alive. Organs commonly donated by living donors include kidneys, a portion of the liver, one lung, a segment of the small intestine, as well as tissues like skin, bone marrow, one testis, or one ovary. Live donors can be related or unrelated to the recipient.

2. Unrelated Donors

• Unrelated donors choose to donate one of their organs to a recipient they may not be related to, often for altruistic reasons. In some regions, the unrelated donor must have some prior connection to the recipient and no financial transaction should be involved. However, in other countries, even a complete stranger can donate an organ altruistically to someone in need.

3. Deceased Donors

• Organs from deceased donors are harvested when the donor is declared brain dead, and their respiration and circulation are maintained artificially. Brain death certification is typically conducted by a team of doctors designated by the government in organ retrieval centers.

4. Paired Exchange

• When a living donor is not a suitable match for their related recipient but is compatible with another recipient, a paired exchange can be arranged. In this scenario, the second recipient’s related donor may be a suitable match for the first recipient. The surgeries for all four individuals (both donors and recipients) are carried out simultaneously, and donor-recipient anonymity is maintained until after the transplant.

5. Spousal Donation

• A spouse can donate an organ to their partner, provided that their marriage is legally recognized and documented.

Current Scenario: Trends in Organ Donation and Transplantation

Despite advancements in medical science, technology, and increased awareness about organ donation, the disparity between the supply of and demand for organs continues to grow. Each year, the number of people on organ transplant waiting lists increases, encompassing both deceased and living donor scenarios.

Statistics from the Organ Procurement and Transplantation Network (OPTN) Annual Report illustrate the following trends:

• In 2016, a total of 41,335 organs were donated, which could be from either deceased or living donors. Four out of every five donations came from deceased donors, while four out of ten came from living donors.
• According to the OPTN 2018 report, there were 115,033 individuals in need of life-saving organ transplants, with 74,926 actively waiting for suitable donors.

Understanding the motivations behind living organ donation can be complex. In recent times, financial incentives have become a driving factor for donation. Additionally, personal relationships have played a significant role in increasing donation rates. One potential solution to mitigate the shortage of available organs is to encourage more individuals to register as posthumous organ donors. By doing so, the issue of organ scarcity could be alleviated.

This trend is expected to continue to gain momentum in the coming years. Organ procurement organizations and healthcare accreditation bodies, such as the Joint Commission on Accreditation of Healthcare Organizations, actively work to increase donation rates. These organizations take various steps to challenge traditional social taboos surrounding organ donation.

One approach gaining traction is known as “donation after cardiac death” (DCD). This method often involves patients who have sustained brain damage, such as from a car accident or stroke. After family members make the difficult decision to discontinue life-sustaining treatments, representatives from organ banks discuss the possibility of organ donation. Occasionally, individuals with incurable diseases also make the decision to become organ donors.

In India, as in many other parts of the world, the demand for organs has surged dramatically. Organ shortages are particularly acute, with limited solutions available. It is estimated that each year, 1.5 lakh people in India suffer from renal failure, but only 3,000 of them receive donors. Similarly, approximately 2 lakh people die from liver failure or cancer annually, with few receiving organ donations. Heart transplant patients face a similarly dire situation, with only 15 hearts available for every 50,000 heart attack patients. There is an urgent need for widespread awareness campaigns in India to bridge the gap between organ supply and demand.

The primary reasons for organ shortages in India are a lack of awareness and knowledge. Many people remain uninformed about the benefits of organ donation. In today’s age of social media and various communication platforms, there is ample opportunity to promote the positive aspects of organ donation and how it can save countless lives if more individuals register as donors. Myths and superstitions also contribute to organ shortages. Many people refrain from donating their organs even after death due to unfounded beliefs. Some individuals with existing medical conditions or older adults who wish to donate are often deterred because they wrongly believe they are ineligible. In reality, almost anyone can donate some organs or tissues unless they have extreme medical conditions.

The pressing need for organ donation arises from the fact that out of the 1.5 lakh people in India who require kidneys, only 3,000 receive them. This means only 1 out of every 30 people in need of a kidney actually gets one, and a staggering 90% of people on the waiting list die without receiving a donor kidney. Approximately 70% of liver transplants depend on living donors, but the remaining 30% rely on cadaveric (deceased donor) donations. Consequently, there is an urgent imperative to increase organ donation rates and offer individuals a second chance at life.

Challenges in Organ Donation:

When it comes to challenges in organ donation, several factors come into play, including the motives of donors, the decision-making process, the psychological state of donors, and their fitness as potential donors.

Pre-Donation Challenges

Donor’s Motives

Donors are often motivated by a combination of factors, both intrinsic and extrinsic. Intrinsic factors may include a desire to alleviate the suffering of another individual or adherence to religious convictions. Extrinsic factors can encompass social pressures or perceived societal norms. The precise blend of motivational forces can vary depending on the donor’s relationship to the recipient.

For living related donors, it’s commonly assumed that family members or emotional partners are primarily motivated by the desire to save the lives of their loved ones. Studies conducted over the past few decades have consistently shown that such motives are the most frequently expressed feelings. In contrast, non-directed living donors (individuals donating to unrelated patients whom they did not select) may be motivated by altruistic or humanitarian motives, along with beliefs that their own self-worth will be enhanced, feelings of moral and religious obligation, or self-identity.

Donor’s Decision-Making

The decision to donate an organ is ultimately the donor’s own decision and can be influenced by various factors, including the donor’s relationship with the recipient. The speed at which a decision is made can provide insights into the type of decision being considered. There appear to be two primary decision-making approaches: moral decision-making and rational decision-making.

• Moral Decision-Making: This involves an awareness that one’s actions can impact another person, a sense of personal responsibility, acceptance of social or moral norms governing the behavior, and taking action in line with those norms. Moral decision-making tends to lead to non-deliberative, instantaneous decisions.
• Rational Decision-Making: In contrast, rational decision-making involves several steps, such as gathering relevant information, evaluating alternatives, selecting the best course of action, and implementing the decision. It is a more deliberative and systematic process.

Support

Assessing the available physical, financial, and emotional support for the donor is crucial. It’s essential to determine if the donor will have someone to provide care during the recovery period, whether they have sufficient financial support, and other forms of assistance. This is important to prevent distress if complications arise. Additionally, it’s vital to determine if the donor has the support of significant others for their decision or if they are choosing to donate against objections from people who have a legitimate interest in the outcome of their autonomous decision.

Family Attitudes Toward Donation

The attitudes of the donor’s spouse and family members regarding donation should also be explored. Collateral interviews with significant others, especially those who will be providing tangible support during the donor’s recovery, should be conducted whenever possible. Addressing conflicts between potential donors and their significant others before surgery can help avoid future conflicts. Family members should have a clear understanding of the donor’s wishes and motives, even if they don’t fully agree with the decision.

Behavioral and Psychological Health

The behavioral and psychological health of the donor should be assessed before donation. It’s important to determine if the donor’s lifestyle is healthy enough to minimize unnecessary risks for both the donor and recipient. Some potential donors may have unhealthy behaviors, such as moderate obesity or smoking. It’s essential to assess if there is sufficient time for the donor to mitigate these risks, such as losing weight or quitting smoking. Additionally, the donor’s emotional stability in coping with stresses before, during, and after donation is crucial. Identifying the psychological and behavioral status of the donor is important, as it can impact their quality of life post-donation.
