[Reasons and Influencing Factors for the Willingness to Document Preferences Regarding Organ Donation: Results of an Online Survey]. / Gründe und Einflussfaktoren für die Bereitschaft zur Dokumentation von Präferenzen bezüglich Organspende. Ergebnisse einer Online-Umfrage.

ABSTRACT

OBJECTIVE: Different options to regulate decisions about organ transplantation were subjected to discussions prior to parliamentary decision on 16.01.2020. The goal of this study was the description of citizens' attitudes towards organ donation and investigation of predictors of (documentation of) willingness to donate. METHODS: Cross sectional online survey in Berlin and Saxony-Anhalt between 25.11.2019 till 16.01.2020. Descriptive, statistical analysis. We report absolute and relative frequencies. We conducted logistic regression analysis for the influence of age, income and gender on knowledge, willingness to donate and possession of an organ donor card. RESULTS: Of 20 020 invited citizens, 676 (3.4%) participated in the online survey; 54.9% were in favour of an opt-out regulation, 49.4% supported an opt-in regulation, 63.3% of respondents were willing or rather willing to donate an organ and 43.2% possessed an organ donor card. Willingness to donate and possession of an organ donor card decreased with increasing age. A Higher educational level was associated with having an organ donor card. Gender, income, education and knowledge about organ donation were not associated with the willingness to donate an organ. Of those who were willing to donate but who had not a donor card, 45.7% had communicated their will to relatives. Reasons indicated for lack of documentation included practical reasons as also fears related to medical care in case of critical health state. DISCUSSION: None of the discussed legislative regulations on organ donation has been supported by a clear majority of respondents. Distinct population-based surveys can serve as starting point for developing targeted initiatives to increase the documentation of citizens' will regarding organ donation following brain death.
