To evaluate the accuracy of defining characteristics and causal relationships of the etiological factors of the nursing diagnosis deficient knowledge in individuals with heart failure .
An analytical, cross-sectional study on the diagnostic accuracy of the defining characteristics and causal relationships of the etiological factors of the nursing diagnosis. The sample consisted of 140 patients with chronic HF and in outpatient follow-up. The latent class analysis method was used to test the accuracy of measurements and estimate the prevalence of the diagnosis. The calculation of subsequent probabilities and the odds ratio ( were also parameters employed. The study was approved by the Research Ethics Committee of the Federal University of Pernambuco.
The diagnosis had an estimated prevalence of 38.57% in the sample. The inaccurate statements about the disease and/or therapy, self-care deficient performance, and inadequate behavior were the clinical indicators that best predicted the presence of the diagnosis and demonstrated the same sensitivity value (1.0000), specificity (1.0000), and 95% confidence interval (0.9999-1.0000) for all. The populations at risk was elderly (OR = 2.12, confidence interval 95% = 1.05-4.27), and illiterate individuals (OR = 2.07, confidence interval 95% = 1.03-4.16) had an approximately twofold great chance of developing havening deficient knowledge.
The evaluation of the accuracy of clinical indicators, corresponding to the defining characteristics in the study, contributed to screening and diagnostic establishment capacity in clinical practice, and to the translation of theoretical and practical knowledge.
Accurate clinical indicators of the nursing diagnosis deficient knowledge facilitate the clinical reasoning of nurses and favor the professional's role in the development of health education strategies focused on the acquisition of knowledge about the disease by patients, family members, and caregivers.
评估将心力衰竭个体的护理诊断知识不足的病因因素的定义特征和因果关系准确界定的能力。
一项关于护理诊断知识不足的病因因素的定义特征和因果关系的诊断准确性的分析性、横断面研究。样本由 140 名慢性心力衰竭门诊随访患者组成。采用潜在类别分析方法测试测量的准确性并估计诊断的患病率。随后还计算了概率和比值比（OR）。该研究得到了伯南布哥联邦大学研究伦理委员会的批准。
在样本中，该诊断的估计患病率为 38.57%。关于疾病和/或治疗、自我护理表现不足和行为不当的不准确陈述是预测诊断存在的最佳临床指标，其灵敏度值（1.0000）、特异性（1.0000）和 95%置信区间（0.9999-1.0000）均相同。高危人群为老年人（OR=2.12，95%置信区间 1.05-4.27），而文盲个体（OR=2.07，95%置信区间 1.03-4.16）发生知识不足的可能性约为两倍。
评估与研究中的定义特征相对应的临床指标的准确性有助于提高临床实践中的筛选和诊断能力，并促进理论和实践知识的转化。
准确的护理诊断知识不足的临床指标有助于护士的临床推理，并有利于护士在制定以患者、家庭成员和照顾者获得疾病知识为重点的健康教育策略方面发挥专业作用。
