Self-care is one of the main factors altered in the life of a person with an ostomy. Self-care requisites with nursing support are necessary. Objectives: To map the self-care requisites for people with intestinal ostomies in their adaptive process, guided by Orem’s theory. Materials and methodology: A scoping review was conducted between May and June 2022, in which studies published from 2000 to 2022 were selected, based on Orem’s self-care deficit nursing theory. The sources of evidence used were Medical Literature Analysis and Retrieval System Online, Cinahl, Scopus, Latin American and Caribbean Health Sciences Literature, Nursing database, Índice Bibliográfico Español en Ciencias de la Salud, Web of Science, Scientific Electronic Library Online, Brazilian Digital Library of Theses and Dissertations, Open Access Scientific Repositories of Portugal, Theses Canada, DART-Europe E-Theses Portal, and National ETD Portal. Studies presenting at least one requisite of self-care for people with intestinal ostomies, whether or not they addressed Orem’s theory, and that were published in full were included. We followed the recommendations of the Joanna Briggs Institute and the PRISMA International Guide, registered in the Open Science Framework (10.17605/OSF.IO/XRH5K). The following descriptors and search strategies were used: (ostomy OR colostomy OR ileostomy OR stoma) AND (self-care OR self-management) AND (adaptation OR adjustment). Results: The final sample was composed of 87 studies. In universal requisites, studies in the category “nutritional aspects” predominated, of which the most frequent was “eat regularly and follow a balanced diet” (23; 26.4%); in developmental requisites, the prevalent category was “stoma and peristomal skin care” and requisite “assess peristomal skin integrity” (27; 31.0%); in the health deviation requisites, the predominant category was “choice of collection equipment and adjuvant products” and the requisite “use hydrocolloid powder to absorb moisture in cases of dermatitis” (13; 14.9%). Conclusions: The study contributes to guiding the assistance to the person with an ostomy, improving the self-care learning process. However, new intervention studies are still needed.
