Introduction: Prevention of recurrence after an episode of venous thromboembolism (VTE), and also the post-thrombotic syndrome (PTS), is still a recognised challenge. In this meta-analysis, we will summarise existing evidence to compare intelligent system follow-up and routine follow-up for patients with VTE.
Methods and analysis: Relevant randomised controlled trials (RCTs) and cohort studies will be included from the following databases: MEDLINE/PubMed, Web of Science and the Cochrane Library. The last search time will be 31 March 2024. Two reviewers will independently identify RCTs and cohort studies according to eligibility and exclusion criteria. The risk of bias of included cohort studies will be assessed with the Newcastle-Ottawa Scale, Methodological Index of Non-Randomised Studies, and the risk of bias of RCTs will be assessed with and Cochrane Collaboration's tool. The primary outcomes include overall survival rate and PTS incidence rate. The Grades of Recommendations, Assessment, Development and Evaluation tool will be used to assess the level of evidence for outcome from RCTs. RevMan V.5.4 software will be used to pool outcomes.
Ethics and dissemination: Ethical approval was obtained from Shanghai Ninth People's Hospital, Shanghai JiaoTong University School of Medicine Science Research Ethics Committee (SH9H-2023-T466-1). The findings will be disseminated to the public through conference presentations and publication in peer-reviewed scientific journals.
