Objective: Identify prognostic factors for delayed healing of complex wound types in adults. Introduction: The high prevalence of persons with wounds and its consequences for person's quality of life makes the issue a relevant focus of attention for healthcare professionals. In this way, by knowing the prognostic factors, the individual risk of complications can be predicted, making it possible to alert to imminent delays and guide decision-making, helping healthcare professionals and the person himself. Inclusion criteria: This review will consider all quantitative and mix studies that include adults with complex, chronic or difficult to heal wounds and report the prognostic factors for delayed healing in any care settings. Methods: Scoping review according to Joanna Briggs Institute (JBI) methodology and guided by the Preferred Reporting Items for Systematic Reviews extension for Scoping Reviews (PRISMA-ScR) checklist. Published studies will be searched through Medline, CINAHL, Nursing & Allied Health Database, Scopus, Cochrane Library and Web of Science and, also will include unpublished in repositories, Google Scholar, and wound care or tissue viability societies. Full texts included in Portuguese, Spanish, French and English in the last 5 years. The selection of articles will be carried out by two reviewers independently, using EndNoteWeb and Rayyan and will use a table designed by the authors for data collection. Prognostic factors will be presented in graphs by years and publication locations, study design, wound types, and measurement methods.
