Attitudes of Hand Surgeons and Hand Reconstruction Patients Toward Hand Allotransplantation in Taiwan

Recent advances in immunosuppressive protocols have increasingly made hand allotransplantation a realistic reconstructive option with more than 100 cases performed worldwide. While attitudes toward allotransplantation have been assessed for North American surgeons and patients alike, similar assessments have previously remained unconducted in Asia in general and Taiwan in specific. This study examines the perceptions of both Taiwanese hand surgeons and hand reconstruction patients.

An email-based survey was sent to all active members of the Taiwanese Society for Surgery of the Hand. Surgeon training backgrounds and practice profiles were gathered as well as current beliefs on indications, risks, ethicality, priority of psychosocial issues, and obstacles to implementation. Patients receiving rehabilitation at Chang Gung Memorial Hospital Linkou after severe upper extremity injuries were invited to complete a patient survey. Demographics, injury characteristics, understanding of allotransplantation and immunosuppression, willingness to donate, and willingness to receive transplantation were assessed.

Forty-four hand surgeons responded (24.3% response rate). The majority (61.4%) considered hand allotransplantation to be a high-risk operation, although 40% supported the development of hand allotransplantation under current techniques and immunosuppression. Bilateral hands loss was the most commonly accepted indication for transplant (90.9%), whereas dominant hand loss was less frequently accepted (43.2%). Treatment compliance and functional outcomes were the most frequent psychosocial issues of concern regarding patient counseling. Patient respondents were mostly in the fifth decade of life (29.5%) with at least a high school education (75.0%). Most were aware of the feasibility of hand transplantation (68.2%). Patients were more likely than surgeons to consider nondominant hand, multiple-digit, and thumb-only amputations as indications for transplantation. Functional outcomes and financial considerations were the most frequent patient concerns.

This study indicates there is support for hand allotransplantation as a solution for limb loss in both hand surgeons and hand patients in Taiwan. This study adds to the lack of knowledge regarding surgeon and patient attitudes toward allotransplantation in Asia, although further work is required to assess the willingness of broader Taiwanese medical to refer candidates and for the general population to donate.
