Diagnostic accuracy of clinical indicators of Imbalanced nutrition in pediatric patients submitted to chemotherapy.

To analyze the accuracy of clinical indicators of nursing diagnosis, Imbalanced nutrition: less than the body requirements in pediatric patients undergoing chemotherapy. A cross-sectional study was carried out in a pediatric oncohematology unit. A total of 123 children aged 5-18 years were evaluated. The Standards for Reporting Diagnostic Accuracy Studies (STARD) protocol was used. Latent class analysis was performed to obtain sensitivity and specificity of clinical indicators. The diagnosis was identified in six children (5.23%). The most frequent clinical indicator in the study was report of food intake less than recommended daily allowance (n = 61; 49.6%), followed by excessive hair loss (n = 49; 39.8%), misperception (n = 42; 34.1%), satiety immediately upon ingesting food (n = 32; 26%), lack of information (n = 30; 24.4%), and pale mucous membranes (n = 22; 17.9%). The 10 indicators that sensitivity and specificity were statistically superior to 50% were food intake less than recommended daily allowance, misperception, insufficient interest in food, lack of food, hyperactive bowel sounds, body weight 20% or more below ideal weight range, insufficient muscle tone, food aversion, abdominal cramping, and misinformation. The clinical indicators Food intake less than recommended daily allowance and Misperception can be considered the most important indicators for the initial inference of the diagnosis due to their high values of specificity and sensitivity. It is essential that nurses provide targeted and qualified assistance based on the signs and symptoms presented by patients, as they will be able to design appropriate interventions to obtain the desired results.
