Classification tree for the inference of the nursing diagnosis Fluid Volume Excess (00026)

Abstract

Objective: To generate a Classification Tree for the correct inference of the Nursing Diagnosis Fluid Volume Excess (00026) in chronic renal patients on hemodialysis. Method: Methodological, cross-sectional study with patients undergoing renal treatment. The data were collected through interviews and physical evaluation, using an instrument with socio-demographic variables, related factors, associated conditions and defining characteristics of the studied diagnosis. The classification trees were generated by the Chi-Square Automation Interaction Detection method, which was based on the Chi-square test. Results: A total of 127 patients participated, of which 79.5% (101) presented the diagnosis studied. The trees included the elements “Excessive sodium intake” and “Input exceeds output”, which were significant for the occurrence of the event, as the probability of occurrence of the diagnosis in the presence of these was 0.87 and 0.94, respectively. The prediction accuracy of the trees was 63% and 74%, respectively. Conclusion: The construction of the trees allowed to quantify the probability of the occurrence of Fluid Volume Excess (00026) in the studied population and the elements “Excessive sodium intake” and “Input exceeds output” were considered predictors of this diagnosis in the sample.

Predictors of excess fluid volume in hemodialysis patients: an observational study

“…A study on excess fluid volume in hemodialysis patients confirms this finding. It was found that excessive sodium intake is a predictive factor for occurrence of water overload in this clientele, demonstrating a probability of occurrence of 87.5% (26) . After a meal rich in sodium, thirst increases.…”

“…In this aspect, there is a need for educational measures aimed at self-care, about the disease, treatment and repercussions on health due to low adherence (26) . A study states that cell phone text messages are a well-accepted strategy as a counseling support for people on hemodialysis to improve eating behaviors.…”
