Acceptance of xenotransplantation by patients waiting for organ donation: A qualitative study

Exploring attitudes toward xenotransplantation: A scoping review of healthcare workers, healthcare students, and kidney patients

BACKGROUND

Recent advances mean that formal clinical trials of solid organ xenotransplantation are increasingly likely to begin and patients requiring a kidney transplant could be the first participants. Healthcare workers and healthcare students constitute the current and future workforce that will influence public opinion of xenotransplantation. The attitudes of these populations are important to consider before recruitment for formal clinical trials begins.

METHODS

This scoping review was reported according to the PRISMA extensions for scoping reviews checklist and the Joanna Briggs Institute methodology for scoping reviews. The Scopus, PubMed, and ScienceDirect databases were searched to identify articles that studied the attitudes of healthcare workers, healthcare students, or kidney patients toward xenotransplantation.

RESULTS

The search generated 816 articles, of which 27 met the eligibility criteria. The studies were conducted in 14 different countries on five different continents. Participants from the 27 studies totaled 29,836-this was constituted of 6,223 (21%) healthcare workers, 21,067 (71%) healthcare students, and 2,546 (8%) kidney patients. All three groups had an overall positive attitude toward xenotransplantation. However, in studies where participants were asked to consider xenotransplantation when the risks and results were not equal to allotransplantation-the overall attitude switched from positive to negative. The results also found that Spanish-speaking populations expressed more favorable views toward xenotransplantation compared to English-speaking populations.

CONCLUSION

The results of this review suggest that while attitudes of the three groups toward xenotransplantation are-on the face of it-positive, this positivity deteriorates when the risks and outcomes are framed in more clinically realistic terms. Only formal clinical trials can determine how the risks and outcomes of xenotransplantation compare to allotransplantation.

Moral approval of xenotransplantation in Egypt: associations with religion, attitudes towards animals and demographic factors

Xenotransplantation has great potential as an alternative to alleviate the shortage of organs for donation. However, given that the animal most suited for xenotransplantation is the pig, there are concerns that people in Muslim countries may be more hesitant to morally approve of these procedures. In this study, the moral approval of xenotransplantation was assessed in a group of 895 participants in Egypt. The results showed that religiosity itself does not predict moral approval of xenotransplantation, but religious identity does, as Muslims are less likely to approve of xenotransplantation than Christians. However, the strongest predictor of moral approval of xenotransplantation was gender, with women displaying less approval. A partial mediating factor in this association was concern for animal welfare. Based on these results, some implications for public policy are discussed.

Evaluation of knowledge, attitude, and awareness of liver transplant patients toward xenotransplantation

BACKGROUND

Xenotransplantation (XTx) is an alternative treatment for organ scarcity. Investigating the acceptance of XTx among patients from diverse cultural and religious backgrounds is essential. This study aimed to evaluate the knowledge, attitudes, and awareness of XTx among patients undergoing liver transplant (LT).

METHODS

This descriptive study was conducted between November 2022 and August 2023. The study population comprised LT patients aged ≥18 years who were admitted to the hepatology clinic of a university hospital in Turkey. Of the 360 patients (n = 360) interviewed, 351 were deemed eligible for inclusion. A questionnaire was used to collect data. The Kolmogorov-Smirnov test, median, standard deviation, minimum-maximum, number, percentage, and Pearson's chi-square test were used for statistical analysis.

RESULTS

Of the patients, 78.3% were religious and adhered to religious requirements, and 87.2% considered their religious beliefs when making important decisions. In all, 41.3% of the participants believed that organ or tissue transplantation from animals to humans is ethical, while 70.1% of the participants believed that organ and tissue transplantation from non-halal animals to humans was impossible. Specifically, 56.7% would not allow organ or tissue transplantation from a non-halal animal to themselves or a relative. Knowledge and attitude towards XTx were not affected by transplantation type (p > .05), but were affected by sex and educational level (p < .05).

CONCLUSION

This study found that LT patients generally oppose XTx. To enhance knowledge and awareness, religious leaders and healthcare professionals should organize comprehensive and effective seminars on this topic.
