Abstract: Objective To explore the effect of nursing model based on Behaviour Change Wheel (BCW) in colorectal cancer patients with stoma. Methods Using convenient sampling method, 100 cases of colorectal post-operative stoma patients admitted to General Surgery Department of the First Affiliated Hospital of Harbin Medical University from January to February 2019 were selected as the research subjects. The patients were divided according to their length of stay, into control group with 46 patients admitted in January 2019, and another 48 patients admitted in February 2019 as observation group. Patients in the control group were given conventional colorectal stoma nursing measures, and those in the observation group intervention based on nursing model established by BCW. The self-management questionnaire and knowledge-attitude-practice scale for patients with colostomy were used to evaluate the effect of the intervention at the day before the surgery and at the end of one and three month after discharge. Results At the first and third month after discharge, the total score and the scores of each dimension of self-management questionnaire of the patients in the observation group were higher than those in the control group, and the differences were statistically significant (P<0.05). The total score and scores of each dimension of knowledge-attitude-practice scale were higher than those of the control group, indicating statistical significance (P<0.05). Conclusion The nursing model based on BCW is effective for improving self-management and the level of knowledge, attitude and practice of patients after enterostomy, which is worth to be promoted.
