Purpose: To propose an evidence-based model (EBM) to improve diagnostic accuracy in nursing.
Data sources: Published literature, experience, and expertise of authors.
Data synthesis: Using an EBM directs clinicians on how to use the best available evidence from the literature to determine the best fit between cues and diagnoses, integrate this evidence with clinician expertise and patient preferences, and conduct a self-evaluation of the process.
Conclusions: Use of an EBM to teach nurses how to ask relevant diagnostic questions and provide a framework for nurse educators to teach evidenced-based practice may lead to developing more competent diagnosticians and improving diagnostic accuracy in nursing.
