Addressing Ireland’s Organ Transplant Shortage: The Human Impact and New Presumed Consent Law

The gap between the demand for life-saving organ transplants and the available supply remains a critical challenge for the Irish healthcare system. While surgical capabilities at centers like the Mater hospital are advanced, the success of these programs is fundamentally tied to donor availability and the regulatory frameworks that govern consent.

The Human Cost of the Transplant Waiting List

For many patients, the period spent on a waiting list is not merely a medical transition but a profound psychological and physical ordeal. Séamus Patton, a Garda detective from Donegal, experienced the progressive decline associated with chronic heart failure. His journey began in 2007 with mitral valve surgery, followed by the implantation of a dual ICD/pacemaker in 2011 to manage life-threatening arrhythmias.

An implantable cardioverter-defibrillator (ICD) serves as a critical fail-safe, monitoring the heart and delivering electric shocks to restore regular rhythms. However, for Patton, the device became a constant reminder of his failing health. “After this, I was living well, playing golf and was active at work, for over a decade. But, in October 2022, I was out playing golf again, and I had a ‘hit’ on my ICD, which propelled me off my feet. I was worked on in the ambulance and, thankfully, I came round, recovered and carried on living again,” he recalls.

As his condition deteriorated, leading to nausea, vomiting, and fluid buildup, the transition from chronic management to transplant candidacy became necessary. “I underwent a three-week assessment in the Mater hospital, before being advised that I was deemed suitable,” says Patton. “I was put on the list, and since then I have got by, but I have vomiting, bad nausea and fluid build up – and on September 12th I was admitted to the Mater due to an issue with my kidney bloods. I got infusions of medication both morning and evening, of up to four hours’ duration.”

The burden of waiting extends beyond the patient. “It’s not easy to be waiting for a transplant, but it was also very difficult for my family, as the waiting game affected them too, in ways such as not seeing my children for weeks at a time, and only seeing my wife at weekends due to work commitments, and the long road that divided us between the Mater and Donegal,” Patton explains. His story illustrates how delays in access are felt not just in clinical outcomes but in lost time, income and family stability.

Systemic Capacity and Donor Shortages

Ireland’s transplant infrastructure faces a persistent shortage of donor organs, which creates a precarious environment for those with advancing diseases. When patients wait longer, their physiological state often declines, increasing the risk and complexity of the eventual procedure and, in some cases, rendering patients too unwell to benefit from a transplant at all.

Consultant thoracic surgeon Aisling Kinsella notes that the clinical condition of the patient at the time of surgery is heavily influenced by the duration of the wait. “But, despite the small numbers on the waiting lists, we are unable to provide transplants for everyone on our active lists due to the shortage of donor organs. And, as patients are waiting longer for transplant, we find that they are sicker going into the operation, which makes the surgery itself more complex,” Kinsella explains. That mismatch between capacity and need has become a strategic concern for health planners as well as a clinical one.

The Regulatory Shift: The Human Tissue Act 2024

To address the shortage of organs, Ireland has moved toward a “presumed consent” model under the Human Tissue (Transplantation, Post-Mortem, Anatomical Examination and Public Display) Act 2024, which is being commenced on a phased basis. The Act provides, for the first time, a national legislative framework for organ donation and transplant services and embeds consent as the central principle across donation and post-mortem practice. From mid-2025, Part 2 of the Act introduces a “soft opt-out” system for adults, aligning Ireland with approaches already in place in several European countries. Full details of the framework are set out by the Department of Health on gov.ie.

• Presumption of Donation: For adults ordinarily resident in Ireland, consent for organ donation is deemed to have been given unless the person has formally recorded an objection during their lifetime.
• National Opt-Out Register: Individuals who do not wish to donate must register their objection via the statutory opt-out register, creating a single, authoritative record that clinicians check at the time of death.
• Family Consultation and Safeguards: Even if a person is not on the opt-out register, next of kin are still consulted as “designated family members”, and no donation proceeds where the family indicates the deceased would have objected.

For government, the move represents a significant policy shift: rather than relying on voluntary donor cards alone, the State now defines a default position in law and expects its hospitals to operate within a common national standard. Health authorities will be required to monitor how the soft opt-out system affects donation rates over time and whether high opt-out levels in certain communities point to gaps in public information or trust.

Despite these regulatory changes, clinicians emphasize that familial communication remains the most effective way to ensure a donor’s wishes are honored. “We would ask the public to discuss their feelings on organ donation, in the event of a catastrophic injury, with their immediate family. The gift of organ donation can save seven people’s lives,” says Kinsella.

Clinical Logistics and Post-Operative Recovery

The window for a successful heart transplant is exceptionally narrow, requiring seamless coordination between ICU staff, Organ Donation Nurse Managers (ODNMs), Organ Donation and Transplant Ireland (ODTI), retrieval teams and transport services like Lifeline. The logistics are a race against time to prevent ischemic damage to the organ and to ensure that the donor and recipient operations are synchronised across different hospitals, often in different parts of the country.

Following the surgery, the focus shifts to immunosuppression and monitoring. Patients must be educated on lifelong medication regimens to prevent the immune system from rejecting the new organ. During the 6-to-8-week hospital stay, clinicians closely track heart function, infection markers and signs of rejection, with follow-up biopsies and outpatient visits extending long after discharge. The Mater’s cardiac transplant team describes this as a “shared-care” phase in which local GPs and regional hospitals also play a role in keeping the new organ stable.

For Séamus Patton, the successful transplant has provided a second chance at a normal life. After seven months in the Mater hospital, he has returned to Co Donegal. “I want to plead to families, have a conversation, think carefully, thoughtfully and give serious consideration to organ donation,” he says. “Organ donation can greatly change the recipient’s life. Sadly, I will never be able to thank the donor personally, and never be able to give them a hug for the wonderful gift of life that may be passed to myself.”

While the road to full recovery remains long, Patton’s outlook is focused on the restoration of his daily routines. “I am not looking for the sun, moon and stars, just looking forward to leading an active life, playing a bit of golf [and] spending time with family.” His experience underscores what is at stake in the State’s policy shift: the possibility of turning a legal change in consent into more lives saved on waiting lists like the one he once faced.

Information on the National Kidney Transplant Service and options for registering a donor card remain available through established patient and advocacy channels, complementing the State’s new opt-out system and giving people additional ways to record and communicate their wishes.
