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.
