Clinical Validation of the Nursing Diagnosis, Decreased Cardiac Tissue Perfusion, in Patients with Coronary Artery Obstruction

Objective To verify the accuracy of the nursing diagnosis, decreased cardiac tissue perfusion, in patients with coronary artery disease. Methods Clinical validation consisted of evaluation by 75 participants. Sensitivity and specificity measurements were performed by means of latent class analysis. Results The prevalence of the diagnosis was 64.5%. Nausea, dizziness, and vomiting were sensitive and specific; altered heart rate was specific. Conclusion Four indicators were accurate for the nursing diagnosis. Implications for nursing Accurate defining characteristics contribute to reliable and precise assessment and enable nurses to diagnose and intervene in the outcome of the patient's clinical condition.
