Taiwan completed its first corpse organ donation in 1969, initiating the development of corpse organ donation. In 1987, Taiwan promulgated and enforced "The Organ Transplantation Act", the first in Asia to legalize the system of organ donation and transplantation. According to statistics spanning from 2011 to 2020, an average of 284 cases of successful organ donations occurred per year, with a record high of 402 donations in 2020. The rate of corpse organ and tissue donation increased from 9.9% per million people in 2011 to 17.1% in 2020, indicating a significant improvement in the number of donors and donation rates. However, based on data from the International Registry in Organ Donation and Transplantation (IRODaT) website for organ donation rates in 2020 worldwide, Taiwan's donation results are still significantly lagging behind western countries.

Taiwan's organ donation mechanism falls under "The Opt-in System", which requires written or testamentary consent from the deceased or consent through written agreement by the closest relatives before organ donation can proceed. Past studies have shown that knowledge, attitudes, and willingness regarding organ donation among the general public and healthcare professionals significantly affect the success of organ donation and proactive recruitment. Therefore, this study aims to investigate the relationship between the knowledge, attitudes, and willingness of organ donors' families and their decisions and to identify other potential factors affecting their choices. The study focuses on the families of successful organ donors and uses descriptive statistical analysis through questionnaire surveys to provide references for promoting organ donation.
