METHOD: convergent care research carried out with 12 nurses. Participant observation, semi-structured individual interviews and convergence groups were used to collect data, which were treated by participatory analysis, with an interpretative approach. RESULTS: the promotion of self-care, the bond between professionals and users, and the support for lifestyle changes for people with diabetes were aligned with the proposed Care Model. On the other hand, attitudes, values and knowledge that weaken care were identified as divergent. The theoretical and practical deepening of the care model, diabetes, dealing with work overload, and the implementation of a guide and a protocol for the development of the nursing consultation were points of convergence for improving the quality of the consultation. It was also observed that nurses' autonomy was strengthened, critical thinking was awakened, and the search for improvement and redefinition of the relationship with the user was sought. CONCLUSION: the nursing consultation was enhanced through the active participation of nurses in an educational, reflective and dialogical process. BACKGROUND: (1) The Nursing Consultation for people with DM by nurses consisted of elements that are similar to and different from the MACC. (2) Elements that align with the MACC: as establishing a bond with users, accountability, longitudinal care, and the social and family approach. (3) Elements diverged from the assumptions of MACC: a limited understanding of the care model, the professional attitude of blaming the user and the weaknesses in the application of the nursing process. (4) The nursing consultation was enhanced through the active participation of nurses in an educational, reflective and dialogical process.
