Organ Transplantation in Argentina

Advancing Cardiac Care: A Registry of Heart Transplantation in Latin America (1968-2022)

INTRODUCTION

Heart transplantation (HTx) has emerged as a pivotal intervention for end-stage heart failure, offering significant improvements in survival and quality of life. This manuscript elucidates the landscape of HTx across Latin America (LATAM) from its advent in 1968 through December 2022, shedding light on its evolution, current practices, and regional disparities.

METHODS

We distributed a structured questionnaire to the national coordinators or representatives of the Interamerican Council of Heart Failure and Pulmonary Hypertension, collating responses from 20 LATAM nations. This approach facilitated a comprehensive aggregation of regional HTx data.

RESULTS

A total of 12,374 HTx were performed in 166 centers across 16 LATAM countries, with Brazil, Argentina, and Colombia accounting for the majority of procedures. Pediatric transplants represented 9% of the total caseload, and combined organ transplants were reported in 62.5% of the participating countries, underscoring the complexity and breadth of transplant services in the region.

CONCLUSION

Despite facing infrastructural and logistical challenges, LATAM has demonstrated a robust capacity to conduct high-complexity transplant procedures. The establishment of a structured, regional HTx registry is imperative to enhance data collection and analysis, which in turn can inform clinical decision-making and policy development, ultimately improving patient outcomes across the continent.

Global legislation regulating the donation, procurement and distribution processes of organs and tissues from deceased donors for transplants: A scoping review

Introduction

Organ transplantation is one of the most successful advances in modern medicine. However, a legal system is necessary for its practice to be free from ethical flaws and to respect donors, recipients, and family members.

Objective

To map the global legislation regulating the donation, capture and distribution processes of organs and tissues from deceased donors for transplants.

Method

A scoping review according to the Joanna Briggs Institute was conducted in the following databases: Medline, CINAHL, Virtual Health Library, SCOPUS, Web of Science, Science Direct, and EMBASE, as well as gray literature, and reported according to the PRISMA extension for scoping reviews.

Results

We identified 3302 records, of which 77 were analyzed which enabled mapping the type of consent adopted and the existence of current legislation for harvesting organs and tissues after circulatory and brain death.

Conclusion

Opt-out consent predominates in Europe, and there is harvesting after brain and circulatory death. Opt-out predominates in the Americas, while Opt-in and harvesting of organs and tissues after brain death predominate in Asia and Oceania. The procurement of organs and tissues from deceased donors is practically non-existent in Africa.

Negotiating treatment and managing expectations in chronic kidney disease: A qualitative study in Argentina

OBJECTIVES

To describe how patients with CKD negotiated assigned responsibilities in the management of their disease, resulting in potential relational nonadherence.

METHODS

Qualitative study performed in two healthcare facilities in Buenos Aires, Argentina, including 50 patients and 14 healthcare providers. We conducted semistructured interviews which were analysed using a frame of reference with concepts of Burden of Treatment and Cognitive Authority theories.

FINDINGS

Adherence to treatment defined "good patients". Patients needed to negotiate starting treatment, its modality and dialysis schedule, although most patients felt they did not participate in the decision process and that providers did not acknowledge implications of these decisions on their routine. Some patients skipped dialysis if concerns were not attended. Regularly, patients negotiated frequency of visits, doses, dietary restrictions and redefined relationships with their support networks, sometimes with devasting effects. As a result of overwhelming uncertainty some patients refused enrolling into a transplant program. When the frequency of complications increased, patients considered abandoning dialysis.

CONCLUSION

When patients perceived demands were excessive or conflicting, they entered into negotiations. Relationally induced nonadherence may arise when professionals do not or cannot enter into negotiations over patients' beliefs or knowledge about what is possible for them to do.

How do social and economic vulnerabilities shape the work of participating in care? Everyday experiences of people living with kidney failure in Argentina

BACKGROUND

A new chronic patient has emerged, with a burden of symptoms and treatment. Patients with kidney failure (KF) require complex and expensive treatments, and in underresourced contexts, they struggle to obtain quality and timely care, even in countries with universal health coverage. We describe how, in such a setting, social structural factors and control over services placed by the system affect the burden of treatment of patients.

METHOD

This qualitative study was undertaken in Buenos Aires, Argentina. Semistructured interviews were conducted with patients with KF (n = 50) and health professionals (n = 14) caring for these patients. Additionally, three types of health coverage were included: public health, social security and private healthcare, with diverse socioeconomic backgrounds.

FINDINGS

Patients' agency to meet demands is extended by relational networks with redistributed responsibilities and roles. Networks provided logistical, financial, emotional support; indeed, patients with limited networks were susceptible to rapid health deterioration, as treatment interruptions could not be identified in time. Control over services translated into scarce information about treatment options, changing dialysis schedules, lack of contact with transplant teams, and new rules to access medication or make requests. For any type of coverage, there was an economic burden related to noncovered medication, copayments, travel, caregivers, specialized diets, and moving to a city offering treatment. Many patients reported economic difficulties that prevented them from even affording meals. Hardships worsened by unemployment because of the disease. Some patients had migrated seeking treatment, leaving everything behind, but could not return without risking their life. Transplanted patients often needed to re-enter the labor market against a background of high unemployment rates.

CONCLUSION

While health policy and practices encourage self-management, the patient may not have the capacity to meet the system's demands. A better understanding of BoT could contribute to improving how patients experience their illness.

Kidney failure, status passage, and the transitional nature of living with the disease: A qualitative study in Argentina

The span of kidney failure (KF) has been extended by advances in treatment. To elucidate the lived experiences of people with KF, we draw on Glaser and Strauss's theory of status passage. Semi-structured interviews were conducted with 50 patients with KF and 14 health professionals, from two healthcare facilities in Buenos Aires, Argentina. The theory informed on the temporal dimensions of people's passages and dimensions related to what actors know of this passage. We described the status passage as a sequence of transitions (starting dialysis, receiving a transplant, returning to dialysis) that have devastating effects on patient's roles, and are accompanied with fear and experience of wasting time. Temporal aspects were crucial and planning was useless; indeed, timing of statuses was uncertain. With a transplant, certain roles and capacities could be regained. Some patients were not aware of the chronic nature of the disease and the ultimate reversibility of the transplant. Control over the passage was minimal because of the unpredictable prognosis of the disease but patients employed strategies to regain it. Control was even more limited for people who migrated to receive a treatment; whose lives were completely altered. Status passage theory signaled the overwhelming impact of the passage on all aspects of people's lives, the uncertainty of the transitions, lack of control and awareness of essential aspects, and unexpected aspects of desirability, adding to our understanding of how people experience this disease and its treatments.

Current status of liver transplantation in Latin America

The lack of adequate financial coverage, education, and the organization has been the main limiting factor for the development of transplantation in Latin America. As occurred worldwide, the number of patients on liver waiting lists in Latin America grows disproportionately compared to the number of liver transplantations (LTs) performed. Although many law modifications have been made in the last year, most countries lack social awareness about the importance of donation and the irreversibility of brain death. The mechanisms and norms for organ procurement and infrastructure development, capable of supporting this high demand, are still in slow progress in most countries. Access to LT in the region is very heterogeneous. While some countries have no active LT programs so far, others are an international model of a public transplantation system (Brazil) or a national information system (Argentina). While some countries have only a few LT centers, others have too many LT centers performing an inadequate low number of LTs. Disparity to access transplantation remains the major challenge in the region. Cultural and educational efforts have to be accompanied by transparent public policies that will likely increase organ donation and activity in transplantation. The purpose of this article is to review the trends and current activity in LT within Latin America, based on prior publications and the information available in each country of the region.
