RESUMOObjetivo: elaborar uma árvore de decisão para formular o diagnóstico de enfermagem "falta de adesão e ansiedade em pessoas vivendo com AIDS". Método: estudo transversal, com abordagem quantitativa, realizado em hospital referência no tratamento de doenças infectocontagiosas no Nordeste do Brasil. A população estudada consistiu em pacientes com AIDS, hospitalizados na unidade hospitalar. A elaboração dos diagnósticos foi processual, realizada simultaneamente com a coleta de dados, buscando identificar as características definidoras e fatores relacionados/de risco de acordo com NANDA-I. Para o tratamento dos dados coletados, os instrumentos foram numerados e as variáveis codificadas e inseridas num banco de dados. Para análise do grau de concordância, o índice Kappa foi escolhido. Resultados: identificaram-se os principais diagnósticos de enfermagem, como a falta de adesão, que estava presente em 100% dos participantes, com índice de concordância superior a 80%. O estudo identificou as principais características definidoras e fatores relacionados/associados ao diagnóstico. Das respectivas características definidoras e fatores relacionados, a árvore de decisão foi elaborada. Conclusão: o modelo de decisão do diagnóstico falta de adesão apresentou as características determinantes, falta de comportamento de adesão e fatores relacionados, conhecimento insuficiente sobre o regime terapêutico e esquema de tratamento complexo. Descritores: Terapia antirretroviral de alta atividade; Síndrome da imunodeficiência adquirida; Aderência à medicamentação. ABSTRACTObjective: to elaborate a decision tree to formulate the nursing diagnosis "lack of adherence and anxiety in people living with AIDS". Method: cross-sectional study, with quantitative approach, carried out in a referral hospital in the treatment of infectious-contagious diseases in Northeast Brazil. The study population consisted of AIDS patients, hospitalized in the hospital unit. The diagnoses elaboration was procedural, performed simultaneously with the data collection, seeking to identify the defining characteristics and related/risk factors according to NANDA-I. For the treatment of the data collected, the instruments were numbered and the variables were coded and inserted into a database. For analysis of agreement degree, the Kappa index was chosen. Results: the main nursing diagnoses were identified, such as a lack of adherence, which was present in 100% of the participants, with a concordance index higher than 80%. The study identified the main defining characteristics and related factors associated with this diagnosis. From the defining characteristics and related factors, the decision tree was elaborated. Conclusion: the decision model of the lack of adherence diagnosis presented the determinant characteristics, lack of adherence behavior and related factors, insufficient knowledge about the therapeutic regimen and complex treatment scheme.

Aim: To identify the nursing diagnoses of the activity/rest domain of NANDA-I Taxonomy II and to analyze the association between the most frequent diagnoses and their defining characteristics, related factors/risk in people living with AIDS. Method: This is a cross-sectional and descriptive study using a quantitative approach. It was performed with 113 patients from March to September 2014. Data were collected using two validated instruments for anamnesis and physical examination. For the elaboration of the diagnoses, the Risner model was followed. And, for purposes of statistical association, the Chi-Square and Fisher tests were used. Results: We identified 30 diagnoses, and only six had a statistically significant association with their components: impaired sleep pattern; fatigue; insomnia; risk of ineffective renal perfusion; impaired walking; deficit in self-care for the bath.  Conclusion: The diagnoses with their associated components provide guidance for the elaboration of nursing interventions as a priority.
