The panel was particularly interested in seeing future high-quality studies of early vs late pharmacological prophylaxis studies in high-risk bleeding patients, examining the benefits and risks of later intervention (days following surgery) once the bleeding risk had greatly subsided. The words “the guideline panel recommends” are used for strong recommendations, and “the guideline panel suggests” is used for conditional recommendations. 13-EHC082-1. The 2013 International Angiology guideline favors LMWH, fondaparinux, VKAs, rivaroxaban, apixaban, or dabigatran, along with use of intermittent pneumatic compression after total hip arthroplasty.403 The most current NICE guideline recommends LMWH or rivaroxaban after total hip arthroplasty and the same after total knee arthroplasty, with the additional option of ASA.401, For VTE prophylaxis after surgery for hip fractures, the 2012 ACCP guideline recommends LMWH for VTE prophylaxis vs fondaparinux and low-dose UFH over adjusted-dose VKAs or ASA.407 Concurrent use of an intermittent pneumatic compression device was also recommended. Following these guidelines cannot guarantee successful outcomes. LMWH vs UFH appears to result in little or no difference in mortality for patients experiencing major trauma (RR, 1.32; 95% CI, 0.14-12.39; low certainty in the evidence of effects). For new reviews, risk of bias was assessed at the health outcome level using the Cochrane Collaboration’s risk of bias tool for randomized trials or nonrandomized studies. Overall, mechanical prophylaxis is recommended for most neurosurgical patients. Pharmacological prophylaxis probably reduces mortality slightly following major gynecological surgery (RR, 0.75; 95% CI, 0.61-0.93; low certainty in the evidence of effects). Further high-quality studies using clinically important outcomes would be of value to improve the certainty in the recommendation. rivaroxaban for the treatment of deep vein thrombosis and prevention of recurrent deep vein thrombosis and pulmonary embolism. The panel determined that there was probably important uncertainty or variability in how much affected individuals value the main outcomes. The trials were reviewed by the panel but were not included in the main meta-analysis because of differences in the comparator groups. This corresponds to 20 more (1-58 more) or 31 more (2-92 more) per 1000 patients, based on baseline risks of 1.6% and 2.6%, respectively, from observational data.73 We are also uncertain whether rates of symptomatic distal DVT are increased (RR, 2.72; 95% CI, 1.41-5.21; very low certainty in the evidence of effects), corresponding to 2 more (1-6 more) to 4 more (1-9 more) per 1000 patients, based on baseline risks of 0.1% and 0.2%, respectively, from observational data.73. After DVT is diagnosed, the main treatment is tablets of an anticoagulant medicine, such as warfarin and rivaroxaban. When pharmacological prophylaxis is used for patients undergoing cardiac or major vascular surgery, the ASH guideline panel suggests using LMWH or UFH (conditional recommendation based on very low certainty in the evidence of effects ⊕◯◯◯). In contrast, for patients at high risk for major bleeding, the large undesirable consequences of major bleeding led to a balance that favors no pharmacological prophylaxis. Pharmacological prophylaxis may be warranted in a higher-risk subgroup of patients, such as those experiencing prolonged immobility following surgery. Venous thromboembolism (VTE), which includes deep vein thrombosis (DVT) and pulmonary embolism (PE), is an important cause of morbidity and mortality among patients with cancer. Some members of the guideline panel were members of ASH. Three studies reported the effect of LMWH prophylaxis vs UFH prophylaxis on risk of mortality, on development of any PEs, and on major bleeding,393-395 whereas 2 studies informed on the risk of development of proximal and distal DVTs.393,394. Therefore, special tests that can look for clots in the veins or in the lungs (imaging tests) are needed to diagnose DVT or PE. [ 1] Acute-Phase Treatment of … Depending on the baseline risk, this benefit likely corresponds to 5 fewer (3-6 fewer) per 1000 patients with a baseline risk of 0.8% to up to 7 fewer (4-8 fewer) per 1000 patients based on a baseline risk of 1.2% from observational data.73 We are very uncertain whether the risks of symptomatic proximal DVTs (RR, 0.14; 95% CI, 0.01-2.63; very low certainty in the evidence of effects) and symptomatic distal DVTs (RR, 1.99; 95% CI, 0.35-11.33; very low certainty in the evidence of effects) differ between the 2 groups. A compararative study of calcium heparinate and sodium pentosan polysulfate, Intraoperative single-dose heparin prophylaxis against deep-vein thrombosis, Efficacy of low doses of heparin in prevention of deep-vein thrombosis after major surgery. We were unable to estimate an effect on symptomatic PEs (RR, not estimable). For researchers: the recommendation is supported by credible research or other convincing judgments that make additional research unlikely to alter the recommendation. For patients undergoing total hip arthroplasty or total knee arthroplasty, the ASH guideline panel suggests using ASA or anticoagulants (conditional recommendation based on very low certainty in the evidence of effects ⊕◯◯◯). Question: Should pharmacological prophylaxis vs mechanical prophylaxis be used for patients undergoing major surgery? There may also be no difference in symptomatic PEs (RR, 0.56; 95% CI, 0.17-1.86; low certainty in the evidence of effects). Where available, questions were addressed with studies that reported symptomatic outcome events. This would correspond to 4 fewer deaths (11 fewer to 5 more) per 1000 patients based on a baseline risk of 7.1% from the control group event rate in the meta-analysis. The panel used an explicit process to rate the clinical severity of DVTs and PEs. An evaluation of the conditions and criteria (and the related judgments, research evidence, and additional considerations) that determined the conditional (rather than strong) recommendation will help to identify possible research gaps. Remark: Twelve hours following surgery was arbitrarily selected to be the cutoff point between early and late postoperative antithrombotic administration. There is a need for large high-quality clinical trials using clinically relevant end points to determine the relative benefits of LMWH vs UFH pharmacological prophylaxis following gynecological procedures. Comparison of low-molecular-weight heparin and unfractionated heparin, Prophylaxis for the prevention of venous thromboembolism after total knee arthroplasty. Further research on the incremental impact of postoperative UFH and LMWH exposure on the development of HIT in this patient population would also be of value. Pharmacological prophylaxis may be warranted in a higher-risk subgroup of patients, such as those experiencing prolonged immobility following surgery. Arbeitsgemeinschaft der Wissenschaftlichen Medizinischen Frachgesellschaften e.V (AWMF). For patients considered at high risk for VTE, combined prophylaxis is particularly favored over mechanical or pharmacological prophylaxis alone. Supplement 2 provides the complete “Disclosure of Interests” forms of all panel members. Rates of symptomatic proximal DVT may be increased with use of IVC filters (RR, 2.19; 95% CI, 1.07-4.50; very low certainty in the evidence of effects), but we are once again very uncertain of this finding. The EtD framework is available online at https://guidelines.gradepro.org/profile/06FDBFB0-4D4E-E0D0-AEAD-C8B371DFA939. For patients undergoing major surgery who receive pharmacologic prophylaxis, the ASH guideline panel suggests using combined prophylaxis with mechanical and pharmacological methods over prophylaxis with pharmacological agents alone (conditional recommendation based on very low certainty in the evidence of effects ⊕◯◯◯). There would probably be no impact on health equity; combined pharmacological and mechanical prophylaxis would probably be acceptable to stakeholders and probably feasible to implement. Recommendations specific to cardiac surgery patients were not presented. Most individuals should follow the recommended course of action. The panel chair was a content expert. The panel recognized that cardiac surgery itself is associated with a risk for the development of heparin-induced thrombocytopenia (HIT). Prophylaxis of postoperative thromboembolism. Low-molecular-weight heparin in combination with intermittent pneumatic compression, Randomized controlled trial of a new portable calf compression device (Venowave) for prevention of venous thrombosis in high-risk neurosurgical patients, Mechanical prophylaxis of venous thrombosis in patients undergoing craniotomy: a randomized trial, A prospective comparison of thromboembolic stockings, external sequential pneumatic compression stockings and heparin sodium/dihydroergotamine mesylate for the prevention of thromboembolic complications in urological surgery, The use of graduated compression stockings in association with fondaparinux in surgery of the hip. These ASH guidelines stand out by their scope, which includes general issues relevant to any surgical procedure and those related to surgical subspecialties. Ten studies reported the effect of mechanical prophylaxis compared with no prophylaxis on risk of mortality.49,77,78,81,83-85,88,90,94 Nine studies reported the effect on the development of symptomatic PEs,37,76,78,81,83,84,86,88,92 and 5 studies reported the effect on any PE.53,77,85,86,93 No study reported data on symptomatic proximal or distal DVT, but 8 studies reported on any proximal DVT,37,78,79,82,84,85,92,93 and 7 studies reported on any distal DVT.37,77,79,82,85,92,93. Question: Should LMWH vs UFH be used for patients undergoing total hip or knee arthroplasty? The panel rated the magnitude of the desirable and undesirable effects of using LMWH over UFH as trivial. The final guidelines, including recommendations, were reviewed and approved by all members of the panel. No comparative information is available regarding the risks of reoperation following hip fracture with the use of LMWH or UFH. David R. Anderson, Gian Paolo Morgano, Carole Bennett, Francesco Dentali, Charles W. Francis, David A. Garcia, Susan R. Kahn, Maryam Rahman, Anita Rajasekhar, Frederick B. Rogers, Maureen A. Smythe, Kari A.

Schünemann, Philipp Dahm; American Society of Hematology 2019 guidelines for management of venous thromboembolism: prevention of venous thromboembolism in surgical hospitalized patients. Studies addressing this question outside the orthopedic setting are most needed. Acute DVT may be treated in an outpatient setting with LMWH. A randomized, double-blind trial comparing enoxaparin with warfarin, Prevention of deep-vein thrombosis after total hip arthroplasty. For patients at high risk for VTE, addition of mechanical prophylaxis to pharmacological prophylaxis is suggested when not contraindicated by lower extremity injury. For patients considered at high thrombosis risk and low bleeding risk, combined mechanical and pharmacological prophylaxis should be considered. This corresponds to 0 fewer (3 fewer to 3 more) major bleeding events per 1000 patients undergoing major general surgery. This corresponds to 2 fewer (0-4 fewer) symptomatic proximal DVTs and 0 fewer symptomatic distal DVTs with the use of LMWH than with warfarin for 1000 patients treated, based on baseline risks of 0.6% and 0.049%, respectively, from observational data.202,203. Most of the evidence comes from orthopedics (elective hip and knee arthroplasty). When pharmacological prophylaxis is used, the panel suggests using LMWH or UFH (conditional recommendation based on very low certainty in the evidence of effects ⊕◯◯◯). Five studies reported the effect of LMWH compared with that of UFH on development of mortality,348,365-368 2 studies reported on the development of PEs,365,366 1 study reported on the development of screening-detected proximal DVTs,348 and 1 study reported on screening-detected distal DVTs.366 Four studies reported risk of major bleeding348,365-367 and 1 study reported on risk of reoperation.366, All participants wore compression stockings, with the exception of 1 study in which their use was not reported.368. We rated the overall certainty in the evidence of effects as very low based on the lowest certainty in the evidence for the critical outcomes, downgrading for study limitations and very serious imprecision. Ultrasound. The EtD framework is available online at https://guidelines.gradepro.org/profile/3B5A5678-B1D9-4D60-8E1F-F3AD700132F8. Use of out-of-hospital prophylaxis, which is routine following total hip or knee arthroplasty, particularly favored DOACs over LMWH, given the need for parenteral administration of the latter agent. Remark: Patients undergoing an extended node dissection and/or open radical prostatectomy may have a higher VTE risk and may potentially benefit from pharmacological prophylaxis. The panel acknowledges that the current recommendation may not reflect standard practice in some centers. There were no relevant adverse events deemed critical for this comparison. Prevention of perioperative deep vein thrombosis in general surgery: a multicentre double blind study comparing two doses of Logiparin and standard heparin. Low-dose heparin versus graded pressure stockings, Comparison of warfarin and external pneumatic compression in prevention of venous thrombosis after total hip replacement, Randomized clinical trial of intermittent pneumatic compression and low molecular weight heparin in trauma, Pneumatic sequential-compression boots compared with aspirin prophylaxis of deep-vein thrombosis after total knee arthroplasty, Safety and efficacy of pneumatic compression with foot-pumps for prophylaxis against deep vein thrombosis after total hip joint replacement. We are equally uncertain about the risk of symptomatic proximal DVTs (RR, 1.01; 95% CI, 0.20-5.0; very low certainty in the evidence of effects) and symptomatic severe distal DVTs (RR, 1.01; 95% CI, 0.30-3.44; very low certainty in the evidence of effects). Resources requirements of warfarin were deemed moderate, particularly with regard to the need for, and the complexity of, anticoagulant monitoring, but cost-effectiveness data probably did not favor warfarin or LMWH. The risk of symptomatic proximal DVT (RR, 0.71; 95% CI, 0.07-6.75; low certainty in the evidence of effects) and symptomatic distal DVT (RR, 0.38; 95% CI, 0.06-2.42; low certainty in the evidence of effects) may be similar between the 2 interventions, irrespective of the baseline risk group. Draft recommendations were reviewed by all members of the panel, revised, and then made available online on 22 June 2018 for external review by stakeholders, including allied organizations, other medical professionals, patients, and the public. Likewise, other questions, such as the duration of pharmacological prophylaxis and timing of the initiation of pharmacological prophylaxis, were also assessed across all surgical domains. The panel recognized that most of the evidence informing this recommendation came from the orthopedic literature (elective knee and hip arthroplasty). Deep vein thrombosis (DVT) and pulmonary embolism (PE) (collectively, VTE) are well-recognized, clinically important, and potentially devastating complications that may occur following major surgical procedures, defined as any surgical intervention that carries greater than minimal risk, is performed in the operating room, and requires specialized training. Studies evaluated included patients with cancer and without cancer. The panel’s work was done using Web-based tools (www.surveymonkey.com and www.gradepro.org) and face-to-face and online meetings. Similarly, the impact of LMWH on symptomatic distal DVTs is very uncertain (RR, 0.33; 95% CI, 0.01-7.93; very low certainty in the evidence of effects). Pharmacological prophylaxis may result in a small increase in major bleeding (RR, 1.24; 95% CI, 0.87-1.77; low certainty in the evidence of effects). Many recommendations have been retained or their validity has been reinforced; however, new data have extended or modified our knowledge in respect of the optimal diagnosis, assessment, and treatment of patients with PE.

Further well-designed studies using clinically relevant end points are required to improve the quality of evidence related to this question. Pharmacological prophylaxis may also reduce the risk of proximal DVTs (RR, 0.51; 95% CI, 0.38-0.69; very low certainty in the evidence of effects), which corresponds to 7 fewer (4-9 fewer) in 1000 higher-risk patients and 3 fewer (2-4 fewer) in 1000 lower-risk patients. We are very uncertain about the effect of LMWH on symptomatic PEs (RR, 2.13; 95% CI, 0.06-81.3; very low certainty in the evidence of effect). For patients undergoing total hip arthroplasty or total knee arthroplasty in which anticoagulants are used, the ASH guideline panel suggests using DOACs over LMWH (conditional recommendation based on moderate certainty in the evidence of effects ⊕⊕⊕◯). For the subset of patients undergoing TURP for whom pharmacological prophylaxis is used, the ASH guideline panel suggests using LMWH or UFH (conditional recommendation based on very low certainty in the evidence of effects ⊕◯◯◯). IVC filters may reduce the risk of symptomatic PE following major surgery and trauma (RR, 0.29; 95% CI, 0.11-0.80; very low in the evidence of effects), but we are very uncertain about this finding. The guideline panel suggests using DOACs rather than LMWH for patients undergoing total hip or knee arthroplasty. The EtD framework is available online at https://guidelines.gradepro.org/profile/EF7ADEA0-49F1-7E89-A0DB-DE7A9E854A2B. Of 8 panel members who voted on this recommendation, 5 voted for recommending either intervention, and 3 voted for a conditional recommendation in favor of anticoagulants.

Pneumatic compression devices vs graduated compression stockings, 4. For patients at low risk for VTE, mechanical prophylaxis was suggested over no prophylaxis, preferably with intermittent pneumatic compression. 191. We rated the overall certainty in the evidence of effects as very low based on the lowest certainty in the evidence for the critical outcomes informed by observational studies. ASH staff supported panel appointments and coordinated meetings but had no role in choosing the guideline questions or determining the recommendations. The guideline panel suggests against pharmacological prophylaxis for patients undergoing TURP. A comparison between unfractionated and low-molecular-weight heparin, Prevention of deep vein thrombosis after elective hip surgery. Question: If pharmacological prophylaxis is indicated, should LMWH vs UFH be used for patients undergoing radical prostatectomy? The resulting recommendations were supported by a systematic review of the procedure-specific VTE risk and the bleeding risk.369,380 For patients undergoing TURP, this resulted in a conditional recommendation against pharmacological prophylaxis across risk groups. Is the 2 hour daily minimum application sufficient? The panel identified that there is a need for large well-designed clinical trials using clinically important end points comparing ASA with other pharmacological methods following total hip and knee arthroplasty. For patients undergoing hip fracture repair, the ASH guideline panel suggests using LMWH or UFH (conditional recommendation based on very low certainty in the evidence of effects ⊕◯◯◯). For each guideline question, the McMaster GRADE Centre prepared a GRADE EtD framework, using the GRADEpro Guideline Development Tool (www.gradepro.org).12,13,16 The EtD table summarized the results of systematic reviews of the literature that were updated or performed for this guideline. The panel judged that pharmacological prophylaxis should be administered to patients undergoing major gynecological surgery, and this recommendation was conditional given the very low certainty in the evidence. For patients experiencing major trauma at high risk for bleeding, the ASH guideline panel suggests against pharmacological prophylaxis (conditional recommendation based on very low certainty in the evidence of effects ⊕◯◯◯). The EtD framework is available online at https://guidelines.gradepro.org/profile/80C377E5-E3C0-36CD-B646-C2532AB4D4B9. Pharmacological prophylaxis results in little or no difference in reoperation (RR, 0.75; 95% CI, 0.21-2.77; low certainty in the evidence of effects).

The EtD framework is available online at https://guidelines.gradepro.org/profile/B2FDFE66-5A79-4E46-875E-9BB7F3FAFF9F. We tested potential differences in the effects with specific drugs and between classes (anti–factor IIa vs anti–factor Xa). Given an assumed baseline risk of 0.2%,370-372 this corresponds to 0 fewer (0 fewer to 0 more) deaths per 1000 patients. The panel judged the costs associated with combined prophylaxis to be moderate based on very low certainty in the evidence about resource requirements. Cost-effectiveness probably favored no pharmacological prophylaxis, whereas issues of equity, acceptability, and feasibility were not deemed important in this setting.

The full article is accessible to AMA members and paid subscribers. Policy makers interested in these guidelines include those involved in developing local, national, or international programs aiming to safely reduce the incidence of VTE and/or to evaluate direct and indirect harms and costs related to VTE and its prevention. Five studies reported the effect of pneumatic compression prophylaxis compared with graduated compression stockings prophylaxis on risk of mortality.94,96,97,101,102 Eight studies reported the effect on the development of symptomatic PEs,37,95,96,97,98,99,102,103 and 4 studies reported the effect on any PE.94,100,101,103 One study reported data on symptomatic proximal and symptomatic distal DVTs,98 whereas 6 studies reported on any proximal DVT,37,94,96,98-100 and 5 studies reported on any distal DVT.37,94,96,98,100. Preliminary results from a randomized controlled study of low molecular weight heparin vs foot pump compression, Mechanical versus drug prevention of thrombosis after total hip endoprosthesis implantation. The guideline panel judged that, for patients undergoing radical prostatectomy requiring pharmacological prophylaxis, based upon very low certainty in the evidence, LMWH or UFH can be used. and P.D. The EtD framework is available online at https://guidelines.gradepro.org/profile/3532ED1D-6A40-A982-BC3F-6DA318B3B611. The panel based this recommendation on the trivial incremental benefits and the small increased risk of major bleeding associated with pharmacological prophylaxis. The evidence base to inform the relative effectiveness of pharmacological prophylaxis vs no pharmacological prophylaxis was comparable to that used to inform this question for patients undergoing laparoscopic cholecystectomy (see Recommendation 18).
