Pharmacological prophylaxis may also reduce symptomatic proximal DVTs (RR, 0.38; 95% CI, 0.14-1.00; very low certainty in the evidence of effects), but we are very uncertain of this finding. Although the panel rated symptomatic VTE end points as those upon which recommendations should be based, the panel recognized that most studies of VTE prophylaxis following surgery used asymptomatic DVTs detected by the routine performance of sensitive screening tests (eg, venography) as the primary study outcome. Depending on patient risk, this corresponds to 0 fewer symptomatic PEs in lower-risk patients to 0 fewer (0-1 fewer) symptomatic PEs per 1000 higher-risk patients undergoing radical prostatectomy. Pharmacological prophylaxis appears to result in little or no difference in mortality (RR, 0.95; 95% CI, 0.84-1.07; very low certainty in the evidence of effects), although we are very uncertain about this finding. The ultimate judgment of a conditional recommendation for DOACs was based on anonymous voting by panel members without direct financial conflicts, with a majority of 5 voting for this recommendation (vs 4 in favor of a recommendation for using either). 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. However, such comparative studies are not regarded as high priority at this time. Should either agent be given, the panel recommended the periodic monitoring of platelet counts.

Health equity would probably be increased as a consequence of the use of ASA. However, it may also increase the risk of proximal DVTs, based on very low quality evidence. There was possibly important uncertainty or variability about how patients may value these outcomes. We are very uncertain about the effect on symptomatic proximal DVTs (RR, 0.38; 95% CI, 0.14-1.00; very low certainty in the evidence of effects). The full article is accessible to AMA members and paid subscribers. This corresponds to 1 fewer (0-1 fewer) symptomatic proximal DVT per 1000 lower-risk patients to 4 fewer (0-5 fewer) per 1000 higher-risk patients.
