Initial management (yellow box) spans the first 5 to 21 days following diagnosis of a new VTE and includes issues concerning whether the patient can be treated at home or requires admission to the hospital, use of thrombolytic therapy, whether an IVC filter needs to be placed, and initial anticoagulant therapy. A second set of trials included adults with objectively confirmed DVT and/or PE who had been treated with anticoagulants for 3 to 6 months without recurrence; they were randomized to receive placebo or continue treatment for ≥6 more months.

Patients in these categories who value rapid resolution of symptoms, are averse to the possibility of PTS, and accept the added risk of major bleeding may prefer thrombolysis. In the subgroup analysis performed for DVT, when using aspirin the certainty in the evidence was judged moderate because of imprecision. The use of thrombolytics for patients with VTE (PE or DVT) was associated with an increase in the risk of major bleeding (RR, 1.89; 95% CI, 1.46-2.46; ARR, 31 more per 1000 patients; 95% CI, 16 more to 51 more; high-certainty evidence) and intracranial bleeding (RR, 3.17; 95% CI, 1.19-8.41; ARR, 7 more per 1000 patients; 95% CI, 1 more to 21 more; moderate-certainty evidence). We considered that the avoidance of PE, DVT, and major bleeding was critical for patients. For patients with breakthrough DVT and/or PE during therapeutic VKA treatment, the ASH guideline panel suggests using low-molecular-weight heparin (LMWH) over DOAC therapy (conditional recommendation based on very low certainty in the evidence of effects ⨁○○○). Consequently, because of this lower risk for mortality and the low certainty in the evidence of effects, the ASH guideline panel has provided a conditional recommendation against the routine use of thrombolytic therapy in these patients. The mean follow-up time was 351 days. As noted in the previous recommendation, any benefit associated with a longer finite course of therapy is lost after anticoagulation is discontinued. We judged that there is probably a large variation in what informed patients may choose. Our analysis showed a potential increase in mortality when using a longer course of anticoagulation than with a shorter course of anticoagulation, without statistical significance (RR, 1.38; 95% CI, 0.85-2.23; ARR, 7 more per 1000 patients; 95% CI, 3 fewer to 22 more; moderate-certainty evidence). 2014;43(6):477], Editor's Choice - efficacy and safety of the new oral anticoagulants dabigatran, rivaroxaban, apixaban, and edoxaban in the treatment and secondary prevention of venous thromboembolism: a systematic review and meta-analysis of phase III trials, Indirect treatment comparison of new oral anticoagulants for the treatment of acute venous thromboembolism, New oral anticoagulants for the treatment of acute venous thromboembolism: are they safer than vitamin K antagonists?

Thrombolytic therapy can be an appropriate intervention in selected patients with PE, as described in Recommendations 6 and 7, and can be administered systemically or using a catheter-directed approach.

Remarks: These recommendations are intended to address the duration of primary anticoagulant treatment for all patients with DVT and/or PE, defined as the minimal length of time for treatment of the initial VTE (Figure 1). An observational study suggested a higher level of patient satisfaction with a DOAC and a lower treatment burden than with LMWH or a VKA.273. In addition, patients with a higher risk of recurrence were excluded from the studies (eg, multiple prior unprovoked VTE, indication for therapeutic dose anticoagulation, or antiphospholipid syndrome). For the baseline risk of major bleeding, we used data from 2 randomized trials on people with VTE; the risk of major bleeding with placebo during an 18-month or 24-month treatment with anticoagulants was as low as 0.5%306  and as high as 1.5% in 18 months.259  The EtD framework is shown online at: https://guidelines.gradepro.org/profile/C151C2DC-8A88-9E05-9D73-2FEB6B917C00. Formal decision aids are not likely to be needed to help individual patients make decisions consistent with their values and preferences. The certainty in the evidence was judged low for mortality because of the serious risk of bias and imprecision and moderate for PE and proximal DVT because of the serious risk of bias. After completion of primary treatment for patients with unprovoked DVT or PE, the ASH guideline panel suggests indefinite antithrombotic therapy over stopping anticoagulation (conditional recommendation based on moderate certainty in the evidence of effects ⨁⨁⨁○). Each EtD table addressed the effects of interventions, resource use (cost effectiveness), values and preferences (relative importance of outcomes), equity, acceptability, and feasibility. The final guidelines, including recommendations, were reviewed and approved by all members of the panel.

One economic evaluation in a Canadian setting based on a decision tree suggests home treatment as cost effective compared with hospital management.41  The other 4 reports suggest that home management leads to cost savings without compromising outcome effects and safety. The EtD framework is shown online at: https://guidelines.gradepro.org/profile/355350CB-41FE-119C-8907-3B646789C1A5. All of them suggested that DOACs are cost-effective relative to VKA.100,104-116. In this case, the high mortality of patients with PE and hemodynamic compromise, as well as the potential lifesaving effect of thrombolytics, warranted a strong recommendation.

First, there needs to be a systematic approach to determine which individuals with PE can be considered for outpatient management.61  Several assessment tools that use baseline clinical information to identify patients at low risk for adverse events during the first few months after diagnosis of PE have been developed, but these prognostic risk scores have not been evaluated prospectively for identification of patients with PE who can be safely treated at home. Participants were randomized to insertion of a nonretrievable IVC filter in addition to anticoagulation or to anticoagulation alone. A controlled clinical study in patients with aortic ball valves, Thromboembolic risk in prosthetic valve carriers. The panel took this factor into consideration by using baseline risks observed in the relevant populations in observational studies and by rating down by indirectness. In the subgroup analysis performed, there are 2 cases in which the quality of the evidence differed from the original analysis. Also, in the trial randomizing individuals with high D-dimer levels to continue or to stop anticoagulation, extended anticoagulation was associated with a higher risk for bleeding (RR, 3.49; 95% CI, 0.14-84.76; ARR, 24 more per 1000 patients; 95% CI, 8 fewer to 813 more; very-low-certainty evidence). The analyses of observational studies also suggested a possible small reduction in long-term mortality at 90 days of follow-up (RR, 0.81; 95% CI, 0.42-1.58; ARR, 18 fewer per 1000 patients; 95% CI, 56 fewer to 56 more; very-low-certainty evidence) or PE (RR, 0.72; 95% CI, 0.07-7.70; ARR, 9 fewer per 1000 patients; 95% CI, 30 fewer to 216 more; very-low-certainty evidence). For patients with unprovoked DVT and/or PE, the ASH guideline panel suggests against routine use of prognostic scores (recommendation 15), D-dimer testing (recommendation 16), or ultrasound to detect residual vein thrombosis (recommendation 17) to guide the duration of anticoagulation (conditional recommendations based on very low certainty in the evidence of effects ⨁○○○). We identified 19 systematic reviews239-257  and 13 RCTs88,258,259,261,262,265,267,298,306-310  (n = 8593) to inform this recommendation. Nederlands Trial Register. For patients who are going to discontinue anticoagulant therapy after completion of the primary treatment phase, the role of aspirin can be considered but needs to be individualized. Decision aids may be useful in helping patients to make decisions consistent with their individual risks, values, and preferences.

Additionally, the certainty in the evidence was rated down because of indirectness in the outcome of PTS, because the only trial that informed this outcome used locoregional thrombolysis instead of catheter-directed thrombolysis. Remarks: This recommendation does not apply to patients who have a high risk for bleeding complications. Home treatment vs hospital treatment (Recommendations 1 and 2), Choice of anticoagulant therapy (Recommendations 3 and 4), Use of fibrinolytic therapy (Recommendations 5-9), Use of IVC filters (Recommendations 10 and 11), Duration of primary treatment (Recommendations 12-14), Choice between stopping anticoagulation and indefinite therapy (Recommendations 15-19), Choice of treatment for secondary prevention (Recommendations 20-22), Management of breakthrough and recurrent DVT/PE (Recommendations 23-25), Decision concerning use of aspirin while on anticoagulant therapy (Recommendation 26), Decision concerning use of compression stockings (Recommendations 27 and 28), The guideline panel assessed the certainty in the supporting evidence and developed and graded the recommendations following the GRADE approach.20-24  The overall guideline-development process, including funding of the work, panel formation, management of conflicts of interest, internal and external review, and organizational approval, was guided by ASH policies and procedures derived from the Guideline International Network–McMaster Guideline Development Checklist (http://cebgrade.mcmaster.ca/guidecheck.html). Finally, stockings are generally available, although they may not be acceptable for some patients and providers given the uncertainty regarding their effect. The ASH guideline panel provided a strong recommendation in favor of indefinite antithrombotic therapy for secondary prevention of recurrent thromboembolism in light of the very high risk of recurrence off anticoagulation. The use of thrombolysis should be rare for patients with DVT limited to veins below the common femoral vein. In most patients with proximal DVT, the ASH guideline panel suggests anticoagulation therapy alone over thrombolytic therapy in addition to anticoagulation (conditional recommendation based on low certainty in the evidence of effects ⨁⨁○○). If these patients can be safely treated with anticoagulant therapy, however, the ASH guideline panel conditionally recommends against the use of IVC filters, based on the low certainty in the evidence of their effects. This recommendation applies to the patient who sustains an unprovoked VTE and who also has a history of an unprovoked VTE that was treated with a time-limited course of therapy that had been discontinued prior to the current event. While guidelines are useful aids to assist providers in determining appropriate practices for many For patients with unprovoked DVT and/or PE, the ASH guideline panel suggests against routine use of prognostic scores (Recommendation 15), D-dimer testing (Recommendation 16), or ultrasound to detect residual vein thrombosis (Recommendation 17) to guide the duration of anticoagulation (conditional recommendations based on very low certainty in the evidence of effects ⨁○○○). For patients with DVT, with (Recommendation 27) or without (Recommendation 28) increased risk for PTS, the ASH guideline panel suggests against the routine use of compression stockings (conditional recommendation based on very low certainty in the evidence of effects ⨁○○○). Recommendations 15 to 17 address the routine use of these strategies. After completion of the primary treatment phase, subsequent decisions (discussed in Recommendation 19) would determine whether to discontinue anticoagulant therapy or continue indefinitely for secondary prevention of recurrent VTE (Figure 2). Patients with acute PE who do not have evidence of hemodynamic compromise, defined as a systolic blood pressure <90 mm Hg or a decrease in systolic blood pressure ≥40 mm Hg from baseline, but who do have evidence of right ventricular strain by echocardiography or elevated cardiac biomarker levels (eg, elevated troponins or natriuretic peptides), have a higher mortality than do patients without these findings.210,211  However, the mortality risk is much less than for those patients with hemodynamic compromise.
