Do alcoholic liver transplantation candidates merit lower medical priority than non-alcoholic candidates?

Should responsibility be used as a tiebreaker in allocation of deceased donor organs for patients suffering from alcohol-related end-stage liver disease?

There is a long-standing debate concerning the eligibility of patients suffering from alcohol-related end-stage liver disease (ARESLD) for deceased donor liver transplantation. The question of retrospective and/or prospective responsibility has been at the center of the ethical discussion. Several authors argue that these patients should at least be regarded as partly responsible for their ARESLD. At the same time, the arguments for retrospective and/or prospective responsibility have been strongly criticized, such that no consensus has been reached. A third option was proposed as a form of compromise, namely that responsibility should only be used as a tiebreaker in liver allocation. The present study provides an ethical investigation of this third option. First, we will provide an overview of the main arguments that have been offered for and against the use of responsibility as an allocation criterion. Second, we will explore the concept of responsibility as a tiebreaker in detail and discuss several types of situations, in which responsibility could be used as a tiebreaker, as well as the main ethical challenges associated with them. As we will show, an ethical justified use of responsibility as a tiebreaker is limited to a very restricted number of cases and is associated with a number of ethical concerns. For this reason, waiting time should be preferred as a tiebreaker in liver allocation, even though the criterion of waiting time, too, raises a number of equity-related concerns.

Ethical issues associated with solid organ transplantation and substance use: a scoping review

While solid organ transplantation for patients with substance use issues has attracted ethical discussion, a typology of the ethics themes has not been articulated in the literature. We conducted a scoping review of peer-reviewed literature on solid organ transplantation and substance use published between January 1997 and April 2016. We aimed to identify and develop a typology of the main ethical themes discussed in this literature and to identify gaps worthy of future research. Seventy articles met inclusion criteria and underwent inductive content analysis. Four main ethical themes were identified: (1) personal responsibility; (2) utility; (3) moral character; and (4) fairness. Each theme had multiple sub-themes and there was substantial overlap between themes. This scoping review identified a disproportionate emphasis in the literature regarding personal responsibility, which was referenced by each of the other themes, and a narrow focus on alcohol and liver. We recommend future research further investigate these connections between ethical themes and focus on ethical issues associated with transplants from organ groups other than liver for patients who use substances other than alcohol.

Predictors of relapse to significant alcohol drinking after liver transplantation

BACKGROUND

End-stage alcoholic liver disease is common, with many of these patients referred for liver transplantation (LT). Alcohol relapse after LT can have detrimental outcomes such as graft loss and can contribute to a negative public perception of LT.

OBJECTIVE

To identify factors that predict the recurrence of harmful alcohol consumption after LT.

METHODS

A total of 80 patients who underwent LT for alcoholic cirrhosis or had significant alcohol consumption in association with another primary liver disease, from July 1992 to June 2006 in British Columbia, were retrospectively evaluated by chart review. Several demographic-, psychosocial- and addiction-related variables were studied. Univariate and multivariate logistic regression analyses were used to test possible associations among the variables studied and a return to harmful drinking after LT.

RESULTS

The relapse rate of harmful alcohol consumption post-liver transplant was 10%, with two patient deaths occurring directly as a result of alcohol relapse. Univariate analysis revealed relapse was significantly associated with pretransplant abstinence of less than six months (P=0.003), presence of psychiatric comorbidities (P=0.016), female sex (P=0.019) and increased personal stressors (P=0.044), while age at transplant of younger than 50 years approached significance (P=0.054). Multivariate logistic regression analysis revealed the following independent factors for relapse: pretransplant abstinence of less than six months (OR 77.07; standard error 1.743; P=0.013) and female sex (OR 18.80; standard error 1.451; P=0.043).

CONCLUSION

The findings of the present study strongly support a required minimum of six months of abstinence before LT because duration of abstinence was found to be the strongest predictor of recidivism. Female sex, younger age at transplant and psychiatric comorbidities were also associated with relapse to harmful drinking.
