Title:
Trend Analysis of Organ and Tissue Donation for Transplantation.

Abstract:
The goal of this study was to identify the tendency toward donations of tissue and organs from donors with brain death between 2001 and 2016 as registered by an organ procurement organization in São Paulo City.
This quantitative, retrospective, exploratory study encompassed all Tissue and Organ Donation Terms signed between 2001 and 2016. A logistic regression model was applied to verify whether there was an upward or downward trend in donation.
After statistical analysis, a significant change trend was identified in skin, bones, valve, vessel, heart, lung, and pancreas donations, indicating an increase in the donation rate through the years. The donation rate did not show changes over the years for donations of liver, kidneys, and corneas.
The decision-making process regarding organ and tissue donation is restricted not only to the dilemma of whether to donate but another question then arises as well: which organs and tissues are to be donated? The discrepancy between the authorization for organ donation and the authorization for tissue donation, as well as the option for one or another organ and/or tissue, must be thoroughly examined because these factors directly affect the number of transplants and acquirements effectively accomplished. These factors may be related to explaining to one's relatives aspects of the surgery, body reassembling, and usage of such organs and/or tissues. They may also be related to the lack of knowledge concerning organ donation and the symbolism represented by the organ and/or tissue, among other factors.
