The Department of Defense, through the Defense Health Agency (DHA), intends to award a sole source contract to the University of Colorado Anschutz Medical Campus (CU Anschutz) for research related to an accelerated clinical protocol aimed at facilitating rapid return to duty after pneumothorax or hemothorax. The objective of this study is to assess the effectiveness and safety of a nurse-driven, physician-supervised protocol that promotes self-ambulatory discharge of patients within 72 hours, addressing critical gaps in military medical care during combat operations. This research is vital as it aims to improve patient outcomes in resource-limited settings, particularly in the context of battlefield injuries. Interested parties must submit their capabilities statements to Tammy McRae at tammy.n.mcrae.civ@mail.mil by 1:00 p.m. Eastern Standard Time on May 20, 2024, to be considered for this opportunity.
