Compression stockings to prevent post-phlebitic syndrome: a living review updated with the OCTAVIA trial

Living systematic reviews (1) and rapid reviews (2) have been proposed to maintain a synthesis of research studies as the evidence base evolves. Accordingly, we have added the OCTAVIA trial to an online living review (3).

Prior to the OCTAVIA trial, we believe the evidence, albeit low quality according to the GRADE rubric, showed benefit from wearing high-pressure compression stockings for two years (see Figure). This is shown when limiting meta-analysis to the two trials with high rates of compliance in wearing of stockings by patients.

The OCTAVIA trial likewise reported benefit among patients with high compliance. This is consistent with the prior trials but OCTAVIA was able to isolate the benefit of wearing stockings in the second year after a thrombosis.

We suggest that practitioners should offer high-pressure stockings for two years at the time of thromboses. While the evidence is of low quality, patients may choose stockings due to the low cost and lack of lasting adverse effects.

The methods underpinning this review are detailed online (3). The review is hosted at GitHub and executed with openCPU. GitHub supports team science and hosts diverse groups and governments with open-source projects including Google and the U.S. National Center for Biotechnology Information.
