Background:
The purpose of this survey was to assess the public's knowledge and attitudes toward vascularized composite allotransplantation and donation.
Methods:
Members of the public (n = 5942) were surveyed using a questionnaire that examined their knowledge and attitudes concerning solid organs (kidney, heart, liver, lung, and pancreas) and vascularized composite tissue (hand/upper extremity, lower extremity, abdominal wall, and face) transplantations and donations.
Results:
Respondents demonstrated greater (all P < 0.05) knowledge and willingness to donate and/or receive solid organs than vascularized composite tissues. Educational level, accurate knowledge, willingness to donate, and willingness to receive were significant (all P < 0.05) determinants of acceptance to donate and/or receive hand/upper extremity, lower extremity, face, and/or abdominal wall.
Conclusion:
The public presented less knowledge and willingness to donate and/or receive hand/upper extremity, lower extremity, abdominal wall, and face.
