Purpose:
To estimate the prevalence of peripherally inserted central catheter (PICC)-related venous thrombosis in patients with hematological malignancies.
Methods:
A systematic review of observational studies that evaluated the occurrence of PICC-related venous thrombosis in children, adults, and older people with hematological malignancies was conducted. Searches were carried out on June 12th, 2023 on PubMed, CINAHL, Embase, Web of Science Core Collection, Scopus, and LILACS, and to gray literature on Google Scholar, and ProQuest Dissertations and Theses Global. Eligibility criteria were applied independently by two reviewers, first on the titles and abstracts on the Rayyan platform and then on the full text of eligible studies. Risk of bias was assessed by the JBI checklist. Data were summarized descriptively, and the meta-analysis was carried out using the MetaXL 5.3 software. The review followed JBI guidelines and PRISMA for reporting.
Results:
In the 40 studies included, prevalence of PICC-related venous thrombosis was 9% in general, 9% in adults, and 6% in children with hematological malignancies. Most studies only evaluated cases of symptomatic thrombosis (n = 25; 64%).
Conclusion:
Patients with hematological malignancies using PICC have an estimated prevalence of PICC-related venous thrombosis of 9%, and this rate may be underestimated due to the consideration of mostly symptomatic cases.
