Abstract
Background: Venous thromboembolism (VTE) is a common source of perioperative morbidity and mortality. Objective: These evidence-based guidelines from the American Society of Hematology (ASH) intend to support decision making about preventing VTE in patients undergoing surgery. Methods: ASH formed a multidisciplinary guideline panel balanced to minimize bias from conflicts of interest. The McMaster University GRADE Centre supported the guideline-development process, including performing systematic reviews. The Grading of Recommendations Assessment, Development and Evaluation (GRADE) approach was used to assess evidence and make recommendations, which were subject to public comment. Results: The panel agreed on 30 recommendations, including for major surgery in general (n 5 8), orthopedic surgery (n 5 7), major general surgery (n 5 3), major neurosurgical procedures (n 5 2), urological surgery (n 5 4), cardiac surgery and major vascular surgery (n 5 2), major trauma (n 5 2), and major gynecological surgery (n 5 2). Conclusions: For patients undergoing major surgery in general, the panel made conditional recommendations for mechanical prophylaxis over no prophylaxis, for pneumatic compression prophylaxis over graduated compression stockings, and against inferior vena cava filters. In patients undergoing total hip or total knee arthroplasty, conditional recommendations included using either aspirin or anticoagulants, as well as for a direct oral anticoagulant over low-molecular-weight heparin (LMWH). For major general surgery, the panel suggested pharmacological prophylaxis over no prophylaxis, using LMWH or unfractionated heparin. For major neurosurgery, transurethral resection of the prostate, or radical prostatectomy, the panel suggested against pharmacological prophylaxis. For major trauma surgery or major gynecological surgery, the panel suggested pharmacological prophylaxis over no prophylaxis.

Bibliographical note
Funding Information:The authors thank Joyce Kirkman and Tracy Minichiello for participation on the panel during the initial stages of the guideline-development process, including to prioritize questions and health outcomes. The authors acknowledge Angela Barbara, Housne Begum, Samantha Craigie, Andrea Darzi, Farid Foroutan, Nora Ibargoyen Roteta, Rana Qadeer, Yasir Rehman, Mansoor Radwi, Matthew Ventresca, and Robby Nieuwlaat for supporting the systematic reviews and Wojtek Wiercioch, Robby Nieuwlaat, and Holger Schünemann for coordination of the systematic review team. Holger Schünemann prepared a template of these guidelines for all panels that was critically reviewed by Adam Cuker, Rob Kunkle, the ASH Guideline Oversight Subcommittee, the Methods Group supporting the guidelines, and Blood Advances editors.
Funding Information:
The work of this panel was coordinated with 9 other guideline panels (addressing other aspects of VTE management) by ASH and the McMaster GRADE Centre (funded by ASH under a paid agreement). Project oversight was provided initially by a coordination panel, which reported to the ASH Committee on Quality, and then by the coordination panel chair (Adam Cuker) and vice chair (H.J.S.). ASH vetted and appointed individuals to the guideline panel. The McMaster GRADE Centre vetted and retained researchers to conduct systematic reviews of evidence and coordinate the guideline-development process, including the use of the GRADE approach. The membership of the panels and the GRADE Centre team is described in Supplement 1.
