Potential for contamination of tourniquets during peripheral venipuncture: a scoping review protocol

Abstract

Background: The tourniquet should be placed above the venipuncture site, thus promoting venous distension. Given its characteristics and use in clinical practice, tourniquets can be a source of microbial contamination. However, the results of scientific studies on this topic are scattered in the literature. Objective: To map the available evidence on the microbial contamination of tourniquets used in peripheral venipuncture, as well as identify health professionals’ practices in handling these devices. Review method: Methodology proposed by the Joanna Briggs Institute. A scoping review protocol was established, which is appropriate to each database/repository, with the purpose of identifying relevant studies that meet the criteria outlined. Two independent reviewers will assess all articles for relevance, as well as perform data extraction and synthesis. Presentation and interpretation of results: The mapping of the potential for contamination of tourniquets and professionals’ practices will contribute to the dissemination of the available evidence. Conclusion: This scoping review is expected to contribute to the critical analysis of the clinical practices in this area, given their potential impact on the safety of care delivery.
