Study Design
In this single-center retrospective review, we evaluated all OCS Lung recoveries performed by our recovery team between May 2019 and January 2021. Recovery data, including transportation and logistical details, was obtained from institutional OCS Lung Run Sheets. Blood traceability and usage data were reviewed using the Sunquest Blood Bank database (Sunquest Information Systems, Tucson, AZ), with specific consideration given to pRBC issuance, transfusion, and waste data for all recoveries. Temperature monitoring data was collected using an ESCORT iLog temperature logger (Cryopak Verification Technologies, Buchanan, VA). According to the University of Chicago Medicine institutional policy, this project received a formal Determination of Quality Improvement status. This initiative was deemed not to be human subject research and was therefore not reviewed by the Institutional Review Board.
