Medical Students’ Clinical Reasoning During a Simulated Viral Pandemic: Evidence of Cognitive Integration and Insights on Novices’ Approach to Diagnostic Reasoning

Abstract

Introduction Cognitive integration from multiple disciplines is essential to clinical problem-solving. Because it is not directly observable, demonstrating evidence of learners' cognitive integration remains a challenge. In addition, little is known about preclinical medical students' approach to diagnostic reasoning despite widespread implementation of clinical reasoning curricula for these early learners. The objectives of this study were to characterize how first-year medical students integrated knowledge to problem-solve during a simulated viral pandemic and to characterize students' diagnostic reasoning approach to this clinical scenario. Materials and Methods Student teams analyzed clinical data to formulate hypotheses for the pandemic's source and submitted reports justifying their hypotheses and treatment recommendations. A content analysis on students' reports identified codes and themes characterizing the learning content integrated and students' approaches to diagnostic reasoning tasks. Results Sixteen problem-solving codes were identified, demonstrating integration of new and previously encountered content from multiple disciplines. A compare-contrast analytical approach was the most commonly employed diagnostic reasoning approach (100%), with a smaller subset of teams also using a causal approach (20%). Discussion Content analysis of preclinical students' diagnostic justification tasks provided insights into their approach to diagnostic reasoning, which was most consistent with the search-inference framework rather than a causal approach, likely due to limited pathophysiological knowledge at that point in training. Conclusions Evidence of cognitive integration can be made explicit through learners' narrative justification of diagnostic reasoning tasks. Preclinical students' diagnostic reasoning development has implications for curricular design and implementation for this learner group.

“…Students tended to use a compare-contrast analytical approach to diagnostic reasoning, with a smaller subset also employing a causal approach. 33 In the content analysis of the 2018 student reports for infection prevention and containment measures (learning objective 5), we identified nine unique codes for public health systems and disaster response-related tasks. Students' most common recommendations were in the infection containment domain, focusing primarily on health care facility measures to mitigate transmission, with fewer reports addressing the community public health and individual citizen levels.…”

Promoting medical student’s clinical reasoning during COVID-19 pandemic

“…Furthermore, students dominantly use the type 2 clinical reasoning process as novices or beginners [ 10 ]. Previous research has indicated that novices employ a pathophysiological analytic method for diagnosis more frequently than a pattern recognition technique, which develops after trainees establish substantial illness scripts through exposure or clinical experience [ 26 ].…”

Does body mass index influence cognitive functions among young medical students?

“…Apart from other non-communicable diseases, evaluation of cognitive impairment is obligatory, as this population is essential to anticipate and diagnose the clinical conditions in routine clinical postings, which depends on their cognitive skills. 11 Body Mass Index (BMI) is a simple, low-cost variable that determines the health status of an individual. 12,13 There is paucity in the literature on the association of BMI and cognitive tasks among young medical students, especially in the Indian population.…”
