Abstract:

Objective To search，evaluate，and summarize the best evidence of insertion and maintenance of mini-midline in adult patients，in order to provide a solid evidence-based foundation for establishing clinical standardized and safe utilization of mini-midline. Methods We systematically searched UpToDate，BMJ Best Practice，Guideline International Network，National Guideline Clearinghouse，Joanna Briggs Institute，National Institute for Health and Care Excellence，Centers for Disease Control and Prevention，Scottish Intercollegiate Guidelines Network，Canadian Medical Association：Clinical Practice Guideline，Registered Nurses’ Association of Ontario，Intravenous Nurses Society，Cochrane Library，PubMed，CINAHL，Embase，Web of Science，Yimaitong，China National Knowledge Infrastructure，Wanfang Database，and China Biomedical Literature Database. It includes clinical practice guidelines，expert consensuses，evidence summaries，systematic reviews，meta-analyses，and best practice on mini-midline insertion and maintenance. The search period covered January 2013 to May 2023. 2 researchers independently evaluated the literature quality and extracted the literature that met the standards. The evidence was graded using the JBI evidence pre-grading system（2014），and the extracted evidence was classified and summarized by themes. Results A total of 10 pieces of the literature were involved，including 6 guidelines，2 expert consensuses，and 2 systematic reviews. This study summarized 20 pieces of best evidence in relation to the following 4 themes：indications and contraindications for mini-midline，catheter insertion，catheter maintenance and catheter removal. Conclusion The study comprehensively and scientifically summarizes the best evidence regarding the insertion and maintenance of mini-midline. We recommend that clinical practitioners integrate this evidence into their practice，while considering individual patient preferences and medical contexts. This approach，in line with the principle of individualization，will contribute to enhancing the standardization and safety of mini-midline use in clinical settings.
