Terminology subset for the International Classification of Nursing Practice in Diabetes Mellitus.

to describe the process of developing a terminological subset for the International Classification of Nursing Practice in Diabetes Mellitus, based on Horta's Basic Human Needs Theory and Bandura's Social Cognitive Theory. a methodological study based on the identification in the literature of 313 statements of nursing diagnoses pertinent to diabetes care, selected and validated by a consensus of nurses from different states of Brazil, specialists in diabetes, using the nominal group technique. 156 nursing diagnosis/result statements were selected, of which 111 (71.15%) related to psychobiological needs, 42 (26.92%) to psychosocial needs and three (1.92%) to psychospiritual needs. A total of 433 nursing interventions were developed. The diagnostic statements were validated on the basis of a consensus among the experts, with an average content validity index of 0.89: 0.87 for psychobiological needs, 0.93 for psychosocial needs, and 0.77 for psychospiritual needs. the study validated the terminological subset for the International Classification of Nursing Practice in Diabetes, favoring clinical reasoning, the qualification of the Nursing Process, and the improvement of self-care practices in diabetes. It has made it possible to use nursing's own language based on a globally recognized classification. (1) Provision of the guiding document for nursing practice in diabetes. (2) Methodological innovation in the development of ICNP® subsets. (3) Advances in knowledge of the basic human needs of people with diabetes. (4) The potential of standardized language for coding and monitoring data. (5) Improving clinical reasoning during nursing consultations.
