Defining Quality Criteria for Success in Organ Donation Programs: A Scoping Review

Background

Well-established performance measures for organ donation programs do not fully address the complexity and multifactorial nature of organ donation programs such as the influence of relationships and organizational attributes.

Objective

To synthesize the current evidence on key organizational attributes and processes of international organ donation programs associated with successful outcomes and to generate a framework to categorize those attributes.

Design

Scoping Review using a mixed methods approach for data extraction.

Setting

Databases included PubMed, CINAHL, Embase, LILACS, ABI Business ProQuest, Business Source Premier, and gray literature (organ donation association websites, Google Scholar-first 8 pages), and searches for gray literature were performed, and relevant websites were perused.

Sample

Organ donation programs or processes.

Methods

We systematically searched the literature to identify any research design, including text and opinion papers and unpublished material (research data, reports, institutional protocols, government documents, etc). Searches were completed on January 2018, updated it in May 2019, and lastly in March 2020. Title, abstracts, and full texts were screened independently by 2 reviewers with disagreements resolved by a third. Data extraction followed a mixed method approach in which we extracted specific details about study characteristics such as type of research, year of publication, origin/country of study, type of journal published, and key findings. Studies included considered definitions and descriptions of success in organ donation programs in any country by considering studies that described (1) attributes associated with success or effectiveness, (2) organ donation processes, (3) quality improvement initiatives, (4) definitions of organ donation program effectiveness, (5) evidence-based practices in organ donation, and (6) improvements or success in such programs. We tabulated the type and frequency of the presence or absence of reported improvement quality indicators and used a qualitative thematic analysis approach to synthesize results.

Results

A total of 84 articles were included. Quantitative analysis identified that most of the included articles originated from the United States (n = 32, 38%), used quantitative approaches (n = 46, 55%), and were published in transplant journals (n = 34, 40.5%). Qualitative analysis revealed 16 categories that were described as positively influencing success/effectiveness of organ donation programs. Our thematic analysis identified 16 attributes across the 84 articles, which were grouped into 3 categories influencing organ donation programs' success: context (n = 39, 46%), process (n = 48, 57%), and structural (n = 59, 70%).

Limitations

Consistent with scoping review methodology, the methodological quality of included studies was not assessed.

Conclusions

This scoping review identified a number of factors that led to successful outcomes. However, those factors were rarely studied in combination representing a gap in the literature. Therefore, we suggest the development and reporting of primary research investigating and measuring those attributes associated with the performance of organ donation programs holistically.

Strengthening Global Efforts to Combat Organ Trafficking and Transplant Tourism: Implications of the 2018 Edition of the Declaration of Istanbul

The 2018 Edition of the Declaration of Istanbul on Organ Trafficking and Transplant Tourism (DoI) provides an updated set of principles and definitions to guide policymakers and health professionals working in organ donation and transplantation. A draft of the new edition was circulated to the public and transplant professionals through an online consultation process, which also sought feedback on a draft explanatory article that explained the principles and discussed some of their practical implications. Both drafts were revised in response to feedback from participants in the consultation. We present here the discussion article, which is intended to assist stakeholders in applying the principles of the DoI by providing more detailed information about the meaning and potential implications of implementing the DoI in various contexts.

Identifying opportunities to increase organ donation after brain death. An observational study in Sweden 2009-2014

BACKGROUND

There is a wide gap between the number of organ donors and patients on waiting lists for transplantation. The purpose of this Swedish nationwide study of the critical pathway for organ donation after brain death (DBD) was to identify missed opportunities for organ donation.

METHODS

We performed a prospective, observational study of all ICU deaths in Sweden from Jan 1, 2009 to Dec 31, 2014. The protocol structure followed the critical pathway for organ donation, which was developed and tested during 2008. We analysed differences in donation incidences between healthcare providers (counties) and patient characteristics using descriptive statistics and logistic regression.

RESULTS

The number of DBD per million population (pmp) was 14.9, varying almost 10-fold from 4.3 to 40.6 DBD pmp between counties. Regional variation in DBD decreased when we assigned the donor to the place of residence (from 6.9 to 27.7 DBD pmp). Women were more likely to become donors compared to men [crude odds ratio (OR) 1.60, 95% confidence interval (CI) 1.38-1.85, P < 0.001]. The increased likelihood remained after adjusting for age, comorbidity, and main diagnostic categories (OR 1.49, 95% CI 1.25-1.77, P < 0.001). An end-of-life decision was found in 50.9% of possible organ donors.

CONCLUSIONS

Regional differences in DBD were considerable, and women were more likely to become donors than men. There is a need for increased awareness of the potential for organ donation as an integral part of end-of-life clinical care. In-depth analysis of these differences may reveal opportunities for action that could lead to increased DBD.

Successful Transplantation of Lungs From an Uncontrolled Donor After Circulatory Death Preserved In Situ by Alveolar Recruitment Maneuvers and Assessed by Ex Vivo Lung Perfusion

We developed a protocol to procure lungs from uncontrolled donors after circulatory determination of death (NCT02061462). Subjects with cardiovascular collapse, treated on scene by a resuscitation team and transferred to the emergency room, are considered potential donors once declared dead. Exclusion criteria include unwitnessed collapse, no-flow period of >15 min and low flow >60 min. After death, lung preservation with recruitment maneuvers, continuous positive airway pressure, and protective mechanical ventilation is applied to the donor. After procurement, ex vivo lung perfusion (EVLP) is performed. From November 2014, 10 subjects were considered potential donors; one of these underwent the full process of procurement, EVLP, and transplantation. The donor was a 46-year-old male who died because of thoracic aortic dissection. Lungs were procured 4 h and 48 min after death, and deemed suitable for transplantation after EVLP. Lungs were then offered to a rapidly deteriorating recipient with cystic fibrosis (lung allocation score [LAS] 46) who consented to the transplant in this experimental setting. Six months after transplantation, the recipient is in good condition (forced expiratory volume in 1 s 85%) with no signs of rejection. This protocol allowed procurement of lungs from an uncontrolled donor after circulatory determination of death following an extended period of warm ischemia.
