Abstract
Objective：It is essential for amniotic membrane banks to have a system of cooperation with obstetrics
departments regarding donations. In 2020, the Kyoto Prefectural University of Medicine Tissue Bank（ hereinafter referred to as the Bank） established a collaborative system with Adachi Hospital, a medical corporation （hereinafter referred to as Adachi Hospital） for the provision of fetal membranes. We will analyze the results over the past five years and consider a sustainable delivery system. Subjects：Data from the Bank’s ledger, amniotic membrane storage records, activity records by certified tissue transplant coordinators, and Adachi Hospital’s donation ledger. Methods：A retrospective analysis of fetal membrane donations over a five-year period from 2020 to the end of 2024 was conducted, including the number of donors, the number of cases that did not result in donation after consent and the reasons for this, and the number of tissues stored in the Bank. We looked back on the operational process of the fetal membrane donation system established between the two facilities. Results：Information was disseminated using digital media, and public awareness pamphlets were created and distributed. All pregnant women referred to this bank consented to donation. There were 13 cases where donation did not take place after consent, eight of which were due to positive group B hemolytic streptococcus tests during prenatal checkups. This information was added to the explanations given to pregnant women from August 2023. The bank and Adachi Hospital share the mission of responding to the desire of pregnant women to contribute to society through donations, and at the end of 2024, they concluded an agreement that included a more comprehensive understanding of their purpose. Discussion：Adachi Hospital was able to secure a stable supply of donors, and the amniotic membrane bank was able to steadily preserve amniotic membranes and prepare and respond to requests from transplant physicians, recipients, and researchers. By raising awareness among medical professionals involved in the donation, donation can contribute to society, commemorate the birth, and create value for pregnant women and their families. In order to respond to the requests of more pregnant women to donate, the amniotic membrane bank promotes the medical use and research of amniotic membranes.
