Psychosocial evaluation of living liver donors-State of current practices in the United States

We surveyed living donor liver transplant programs in the United States to describe practices in the psychosocial evaluation of living donors focused on (1) composition of psychosocial team; (2) domains, workflow, and tools of the psychosocial assessment; (3) absolute and relative mental health-related contraindications to donation; and (4) postdonation psychosocial follow-up. We received 52 unique responses, representing 33 of 50 (66%) of active living donor liver transplant programs. Thirty-one (93.9%) provider teams included social workers, 22 (66.7%) psychiatrists, and 14 (42.4%) psychologists. Validated tools were rarely used, but domains assessed were consistent. Respondents rated active alcohol (93.8%), cocaine (96.8%), and opioid (96.8%) use disorder, as absolute contraindications to donation. Active suicidality (97%), self-injurious behavior (90.9%), eating disorders (87.9%), psychosis (84.8%), nonadherence (71.9%), and inability to cooperate with the evaluation team (78.1%) were absolute contraindications to donation. There were no statistically significant differences in absolute psychosocial contraindications to liver donation between geographical areas or between large and small programs. Programs conduct postdonation psychosocial follow-up (57.6%) or screening (39.4%), but routine follow-up of declined donors is rarely conducted (15.8%). Psychosocial evaluation of donor candidates is a multidisciplinary process. The structure of the psychosocial evaluation of donors is not uniform among programs though the domains assessed are consistent. Psychosocial contraindications to living liver donation vary among the transplant programs. Mental health follow-up of donor candidates is not standardized.

Continuous flow local anesthetic wound infusion for post-operative analgesia following kidney transplantation

BACKGROUND

Some patients with end stage renal disease are or will become narcotic-dependent. Chronic narcotic use is associated with increased graft loss and mortality following kidney transplantation. We aimed to compare the efficacy of continuous flow local anesthetic wound infusion pumps (CFLAP) with patient controlled analgesia pumps (PCA) in reducing inpatient narcotic consumption in patients undergoing kidney transplantation.

MATERIALS AND METHODS

In this single-center, retrospective analysis of patients undergoing kidney transplantation, we collected demographic and operative data, peri-operative outcomes, complications, and inpatient oral morphine milligram equivalent (OME) consumption.

RESULTS

Four hundred and ninety-eight patients underwent kidney transplantation from 2020 to 2022. 296 (59%) historical control patients received a PCA for postoperative pain control and the next 202 (41%) patients received a CFLAP. Median age [53.5 vs. 56.0 years, p = .08] and BMI [29.5 vs. 28.9 kg/m2, p = .17] were similar. Total OME requirement was lower in the CFLAP group [2.5 vs. 34 mg, p < .001]. Wound-related complications were higher in the CFLAP group [5.9% vs. 2.7%, p = .03]. Two (.9%) patients in the CFLAP group experienced cardiac arrhythmia due to local anesthetic toxicity and required lipid infusion.

CONCLUSIONS

Compared to PCA, CFLAP provided a 93% reduction in OME consumption with a small increase in the wound-related complication rate. The utility of local anesthetic pumps may also be applicable to patients undergoing any unilateral abdominal or pelvic incision.

Racial disparities across multiple stages of the deceased organ donation process

Pervasive structural violence causes higher organ failure rates among Black Americans and excess Black potential deceased organ donors. Underuse of Black donors would exacerbate organ shortages that disproportionately harm Black transplant candidates. This study investigates racial differences in transit between distinct donation steps among 132 968 potential donors across 557 hospitals and 6 Organ Procurement Organizations (OPOs) from 2015 through 2021. Multilevel multistate modeling with patient covariates and OPO random effects shows adjusted likelihoods (95% confidence interval [CI]) of non-Black versus Black patients transitioning from OPO referral to approach: odds ratio (OR) 1.23 (95% CI 1.18, 1.27), approach to authorization: OR 1.64 (95% CI 1.56, 1.72), authorization to procurement: OR 1.08 (95% CI 1.02, 1.14), and procurement to transplant: OR 0.99 (95% CI 0.93, 1.04). Overall organ utilization rates for Black, Latino, White, and other OPO referrals were 5.88%, 8.17%, 6.78%, and 5.24%, respectively. Adjusting for patient covariates and hospital and OPO random effects, multilevel logistic models estimated that compared with Black patients, Latino, White, and other patients had ORs of organ utilization of 1.82 (95% CI 1.61, 2.04), 3.19 (95% CI 2.91, 3.50), and 1.25 (95% CI 1.06, 1.47), respectively. Nationwide in 2022, donor conversion disparities likely lost more than 1800 donors-70% of whom would have been Black. Achieving racial equity for transplant candidates will require reducing racial disparities in organ donation.

Successful Liver Transplantation from a Deceased Donor After Ethylene Glycol Ingestion: A Case Report and Review of the Literature of Organ Donation from Poisoned Donors

Despite the increase in deceased organ donation over the past ten years, the gap between patients awaiting transplant and available organs continues to widen. Deceased donors secondary to acute fatal poisonings represent less than 1% of all organ donors. Organs from poisoned donors have largely been discarded due to concerns of toxin transmission and poor organ function as well as the paucity of data that exists regarding this donor population. Here, we report a case of a 40-year-old male who underwent successful liver re-transplantation from a donor who died following ethylene glycol ingestion. To our knowledge this case report is the first to describe successful re-transplantation from an ethylene glycol-poisoned donor. We also provide a comprehensive review of the literature describing organ donation from poisoned donors.
