Intensive Care to Facilitate Organ Donation: A Report on the 4-Year Experience of a Spanish Center With a Multidisciplinary Model to Promote Referrals Out of the Intensive Care Unit

Assessing Outcomes of Patients Subject to Intensive Care to Facilitate Organ Donation: A Spanish Multicenter Prospective Study

Intensive Care to facilitate Organ Donation (ICOD) consists of the initiation or continuation of intensive care measures in patients with a devastating brain injury (DBI) in whom curative treatment is deemed futile and death by neurological criteria (DNC) is foreseen, to incorporate organ donation into their end-of-life plans. In this study we evaluate the outcomes of patients subject to ICOD and identify radiological and clinical factors associated with progression to DNC. In this first prospective multicenter study we tested by multivariate regression the association of clinical and radiological severity features with progression to DNC. Of the 194 patients, 144 (74.2%) patients fulfilled DNC after a median of 25 h (95% IQR: 17-44) from ICOD onset. Two patients (1%) shifted from ICOD to curative treatment, both were alive at discharge. Factors associated with progression to DNC included: age below 70 years, clinical score consistent with severe brain injury, instability, intracranial hemorrhage, midline shift ≥5 mm and certain types of brain herniation. Overall 151 (77.8%) patients progressed to organ donation. Based on these results, we conclude that ICOD is a beneficial and efficient practice that can contribute to the pool of deceased donors.

Comparing demographics of organ donor referrals from the Intensive Care Unit and Outside Units

BACKGROUND

The Spanish organ donation system is a world leader in organ recovery. One of Spain's strategies is identification of organ donor referrals outside of the intensive care unit (ICU) for intensive care to facilitate organ donation (ICOD). There is limited data comparing the profiles of ICU-based and non-ICU ICOD referrals.

METHODS

This single-center retrospective chart review analyzed organ donor referrals of ICU and non-ICU patients to better understand the demographic and clinical differences between cohorts. The primary outcome was to understand if organ donation conversion rates were similar between ICU and non-ICU referrals.

RESULTS

We collected data from 745 organ donor referral candidates, 235 (32%) of whom entered ICOD protocols. Out of this cohort, 144 (61%) became an actual organ donor, 37 of whom (26%) were referred from non-ICU units. The ICU had the highest organ donor conversion rate (66% of ICU ICOD patients became actual organ donors) whereas non-ICU referrals had a 51% conversion rate. Non-ICU unit donors contributed to 21% and 26% of all kidney and liver donations, respectively.

CONCLUSION

Though organ referral candidates from non-ICU units contribute to a small proportion of actual donors, their donated organs are important to sustaining organ donation and transplant activity.

Ethical considerations in the use of pre-mortem interventions to support deceased organ donation: A scoping review

AIM

Pre-mortem interventions (PMIs) are performed on patients before the determination of death in order to preserve or enhance the possibility of organ donation. These interventions can be ethically controversial, and we thus undertook a scoping review of the ethical issues surrounding diverse PMIs.

METHODS

Using modified scoping review methods, we executed a search strategy created by an information specialist. Screening and iterative coding of each article was done by two researchers using qualitative thematic analysis, and narrative summaries of coded themes were presented.

RESULTS

We identified and screened 5365 references and coded 196 peer-reviewed publications. The most frequently cited issues were related to possible harms to the patient who is a potential donor, and legitimacy of consent. The most controversial issue was that PMIs may place patients at risk for physical harm, yet benefit is accrued mainly to recipients. Some authors argued that lack of direct medical benefit to the still living patient precluded valid consent from surrogate decision makers (SDMs), while many stated that some medical risk could be approved by SDMs if it aligns with non-medical benefits valued by the patient.

CONCLUSION

PMIs require consensus that benefit includes concepts beyond medical benefit to the patient who is a potential donor. Informed consent must be confirmed for each PMI and not assumed to be part of general consent for donation. Risk must be proportionate to the potential benefit and newly proposed interventions should be reviewed carefully for medical efficacy and potential risks.

Systematic review of hospital-level metrics and interventions to increase deceased organ donation

BACKGROUND

Efforts to ameliorate the organ shortage have predominantly focused on improving processes and interventions at multiple levels in the organ donation process, but no comprehensive review of hospital-level features contributing to organ donation exists. We undertook a systematic review of the literature to better understand current knowledge and knowledge gaps about hospital-level metrics and interventions associated with successful organ donation.

METHODS

We searched six electronic databases (PubMed, Embase, CINAHL, Web of Science, Health Business Elite, and Google scholar) and conference abstracts for articles on hospital-level features associated with the final outcome of organ donation (PROSPERO CRD42020187080). Editorials, letters to the editor, and reviews without original data were excluded. Our main outcomes were conversion rate, donation rate, number of organs recovered, number of donors, and authorization rate.

RESULTS

Our search yielded 2177 studies, and after a thorough assessment, 72 articles were included in this systematic review. Studies were thematically categorized into 1) Hospital-level interventions associated with metrics of organ donation; these included patient- and family-centric measures (i.e. standardized interviews, collaborative requesting and decoupling, and dedicated in-house coordinators), and donor management goals that significantly increased conversion rates by up to 64%; 2) Hospital-level multi-stage programs/policies; which increased authorization rates between 30 and 50%; and 3) Hospital characteristics and qualities; being an academic center, trauma center and larger hospital correlated with higher authorization and conversion rates. Most studies had considerable risk of bias and were of low quality.

CONCLUSIONS

There is a lack of well-designed studies on hospital-level metrics and interventions associated with organ donation. The use of thoughtful, patient- and family-centric approaches to authorization generally is associated with more organ donors. Future work can build on what is known about the hospital role in organ donation to improve the entire organ donation process.
