An examination of student nurse practitioners' diagnostic reasoning skills.

Aim: To examine the diagnostic reasoning skills of two nurse practitioner student cohorts. Introduction: Nurse practitioners continue to play a pivotal role in health care provision. Diagnostic reasoning is a core skill of advanced practice. A comparative diagnostic reasoning study between two student cohorts was undertaken between 2018 and 2019. Methods: A validated diagnostic reasoning scale was completed by nurse practitioner students in the United Kingdom and the United States of America at the beginning and end of their clinical placements. The study utilized descriptive quantitative statistics from the data submitted by 22 survey respondents from an online survey. Results: Analysis of the diagnostic reasoning skills suggested there was a difference in the structural memory scores when compared with the beginning of their clinical placements and the final semester of their clinical placements. Conclusion: Diagnostic reasoning skills are a core skill of advanced practice. As students progress through their training, these skills improve. Despite the statistical difference in diagnostic reasoning scores, caution should be made in determining any larger implications due to the small number of participants in this study. Further study is needed in this area. Summary statement: What is already known about this topic? Diagnostic reasoning is a core skill for nurse practitioners.There is minimal research in this area.Diagnostic accuracy is vital for ensuring patient safety. What this paper adds? Structural memory scores improved at the end of nurse practitioner clinical placements. What are the implications of this paper for policy/practice/research/education? Further global research in the field of diagnostic reasoning for nurse practitioners and nurse practitioner students is needed to validate these findings.It is important to ensure nurse practitioners have competency in diagnostic reasoning to reduce diagnostic error.Curricula could be designed to incorporate the use of the DTI to evaluate a student's progress throughout the clinical portion of the nurse practitioner programme.
