Background: A Peripherally Inserted Central Catheter (PICC) is a safe and effective Central Vascular Access Device when properly used. Therefore, it has become an increasingly frequent procedure. Nurses are often the professionals responsible for its insertion, maintenance, and removal. Despite the advantages of this device, it presents risks and possible associated complications. This scoping review aims to identify and analyze nursing interventions to prevent complications in adults with PICC. Methods: The review was conducted according to Joanna Briggs Institute’s scoping review proposal. The electronic databases Pubmed, CINAHL Complete, MEDLINE Complete, Cochrane Central Register of Controlled Trials, Nursing & Allied Health Collection: Comprehensive, Cochrane Database of Systematic Reviews, Cochrane Methodology Register, Library, Information Science & Technology Abstracts, and MedicLatina were consulted in October 2023. Additionally, we searched the websites of the Registered Nurses Association of Ontario and the Canadian Vascular Access Association. We included articles published in English and Portuguese between 2018 and 2023. Results: A total of 170 articles were initially identified. After selecting and analyzing the articles, 13 studies were included. This review identified nursing interventions in adults to prevent PICC-related complications, categorized into five main groups: pre-procedure, during the procedure, post-procedure, maintenance, and team management interventions. Nurses are pivotal in averting PICC complications by employing evidence-based nursing interventions at each process stage. Conclusions: The importance of nursing interventions in enhancing patient safety, improving health outcomes, and informing clinical practice highlights the need for standardized protocols, specialized training, and consistent patient education for PICC care.
