George has joined a Laboratory Medicine Best Practices panel whose purpose is to review patterns of preoperative coagulation screening panel usage, in particular, preoperative prothrombin times (PT) and partial thromboplastin times (PTT). We are working on the premise that screening PTs and PTTs fail to consistently predict intraoperative hemorrhage in patients who possess no known coagulopathy, and that the volume of laboratory screening could be reduced and replaced by patient history for a significant savings without sacrificing patient safety. To support the panel’s efforts, I’ve posted a new Quick Question about preoperative screens. Please look it over and give your answer.
It may be that the Quick Question doesn’t cover all situations; please provide a comment below if your institution uses a different approach. Further, the LMBP panel is soliciting unpublished data that may bear upon our goal. If you have any data on screening PT and PTT volumes and outcomes that you would like to share with the panel, please email it to me at [email protected]. All such data will be treated as private and confidential. Thank you for supporting this effort.
