Harms of unsuccessful donation after circulatory death: An exploratory study.

ABSTRACT: While donation after circulatory death (DCD) has expanded options for organ donation, many who wish to donate are still unable to do so. We conducted face-to-face interviews with family members (N = 15) who had direct experience with unsuccessful DCD and 5 focus groups with professionals involved in the donation process. We used qualitative content analysis to characterize the harms of nondonation as perceived by participants. Participants reported a broad spectrum of harms affecting organ recipients, donors, and donor families. Harms included waste of precious life-giving organs and hospital resources, inability to honor the donor's memory and character, and impaired ability for families to make sense of tragedy and cope with loss. Donor families empathized with the initial hope and ultimate despair of potential recipients who must continue their wait on the transplant list. Focus group members reinforced these findings and highlighted the struggle of families to navigate the uncertainty regarding the timing of death during the donation process. While families reported significant harm, many appreciated the donation attempt. These findings highlight the importance of organ donation to donor families and the difficult experiences associated with current processes that could inform development of alternative donation strategies.

Project description:AimTo describe intensive care nurses' conceptions of participating during the donation after circulatory death (DCD) process in intensive care units in Sweden.DesignA qualitative design with a phenomenographic approach.MethodsIn total, 12 semi-structured interviews were conducted in April 2022 with intensive care nurses from three hospitals. Data were analysed using a phenomenographic approach.ResultsConceptions of participating during the DCD process varied. Four main themes emerged: DCD as a system; Intensive care nurses' role in the situation; Life to death to life; The essence of DCD. Variations emerged regarding what the informants talked about and how they talked about the what. Variations were based on informants' perspective of their role in relation to the structure and the team, and their conceptions of care for patients and their relatives.ConclusionThe findings illustrated success factors and challenges. Knowledge, experience, distinct structure, and relationship with relatives, among other factors, were described as success factors, while a lack of experience, difficulty in prognosing death, and organisational obstacles emerged as challenges. Furthermore, the findings showed that intensive care nurses play an important role in optimising the outcome of the DCD process. Their work related to DCD was conceived as being meaningful to fulfil more peoples' wishes to donate organs.ImpactPeople on the waiting list for organ transplantation are dying due to a shortage of organs. The implementation of DCD, as a complement to Donation after Brain Death (DBD), contributed to an increase in the number of organ donors, and intensive care nurses play an important role during the DCD process. Previous research manifests the complexity concerning their role. There is a lack of nursing research regarding intensive care nurses' conceptions of what it means to participate in the DCD process, which emphasises the significance of this study.Reporting methodThis study is reported using consolidated criteria for reporting qualitative research (SRQR).Patient or public contributionNo patient or public contribution.

Project description:ObjectiveDespite growing evidence of comparable outcomes in recipients of donation after circulatory death and donation after brain death donor lungs, donation after circulatory death allografts continue to be underused nationally. We examined predictors of nonuse.MethodsAll donors who donated at least 1 organ for transplantation between 2005 and 2019 were identified in the United Network for Organ Sharing registry and stratified by donation type. The primary outcome of interest was use of pulmonary allografts. Organ disposition and refusal reasons were evaluated. Multivariable regression modeling was used to assess the relationship between donor factors and use.ResultsA total of 15,458 donation after circulatory death donors met inclusion criteria. Of 30,916 lungs, 3.7% (1158) were used for transplantation and 72.8% were discarded primarily due to poor organ function. Consent was not requested in 8.4% of donation after circulatory death offers with donation after circulatory death being the leading reason (73.4%). Nonuse was associated with smoking history (P < .001), clinical infection with a blood source (12% vs 7.4%, P = .001), and lower PaO2/FiO2 ratio (median 230 vs 423, P < .001). In multivariable regression, those with PaO2/FiO2 ratio less than 250 were least likely to be transplanted (adjusted odds ratio, 0.03; P < .001), followed by cigarette use (0.28, P < .001), and donor age >50 (0.75, P = .031). Recent transplant era was associated with significantly increased use (adjusted odds ratio, 2.28; P < .001).ConclusionsNontransplantation of donation after circulatory death lungs was associated with potentially modifiable predonation factors, including organ procurement organizations' consenting behavior, and donor factors, including hypoxemia. Interventions to increase consent and standardize donation after circulatory death donor management, including selective use of ex vivo lung perfusion in the setting of hypoxemia, may increase use and the donor pool.

Project description:Lung transplantation is hampered by the lack of organs resulting in deaths on the waiting list. The usage of donation after circulatory death (DCD) lungs would dramatically increase donor availability. The most optimal organ preservation method, and the need for antithrombotic and fibrinolytic treatment to prevent thrombosis in the donor lungs is currently on debate. The present study investigated, in a simulated clinical DCD situation, whether the addition of alteplase in the flush-perfusion solution at the time of pulmonary graft harvesting could prevent thrombosis in the donor lung and thereby improve pulmonary graft function.Twelve Swedish domestic pigs were randomized into two groups. All animals underwent ventricular fibrillation and were then left untouched for 1 h after declaration of death. None of the animals received heparin. The lungs were then harvested and flush-perfused with Perfadex® solution and the organs were then stored at 8 °C for 4 h. In one group alteplase was added to the Perfadex® solution (donation after cardiac death with alteplase (DCD-A)) and in the other, it was not (DCD). Lung function was evaluated, using ex vivo lung perfusion (EVLP), with blood gases at different oxygen levels, pulmonary vascular resistance (PVR), lung weight, and macroscopic appearance.During EVLP, there were no significant differences between groups in PaO2 at any investigated FiO2 level (1.0, 0.5, or 0.21). At FiO2 1.0, the PaO2 in the DCD and DCD-A was 51.7 ± 2.05 kPa and 60.3 ± 3.67 kPa, respectively (p = 0.1320). There were no significant differences between groups PVR levels, in the DCD (372 ± 31 dyne x s/cm5) and in the DCD-A (297 ± 37 dyne x s/cm5) groups (p = 0.1720). There was no significant difference between groups in macroscopic appearance.All the lungs showed excellent blood gases after EVLP, and they all meet the criteria's for clinical lung transplantation. The use of alteplase did not seem to have any obvious benefit to the donor lungs in a DCD situation. The donor lungs treated with alteplas showed slightly better blood gases and slightly lower PVR compared to the group without alteplas, however the difference was not significant. DCD appears to be a safe and effective method to expand the donor pool.
