Background: The lung CT scan is one of the most important methods for identifying patients with COVID-19. The skill of doctors to interpret CT scan results is very important for disease control and prevention of its serious complications. Therefore, this study was conducted to determine the skill level of intern medical students and emergency medicine residents in interpreting the lung CT scans of patients with COVID-19. Method: The present cross-sectional study was conducted on 100 intern medical students and emergency medicine residents in AJA teaching hospitals in Tehran in 2019. In this study, each participant was given 10 lung CT scans from patients with COVID-19 to interpret. The sex, academic year of the students, and the type of students (intern medical students and emergency medicine residents) were recorded. The mean score of the correct interpretation of the participants was calculated. Then, Chi-square tests or Fisher's exact test, one-way analysis of variance or Kruskal–Walli’s test, and independent t-test or Mann-Whitney test were used to analyze the data. All analyses were performed in Excel and SPSS16 software. All p-values were two-tailed, and the significance level was set at 0.05. Results: In the present study, 61% of the participants were male, and 84% were intern medical students. The mean correct interpretation score of lung CT-scan results was 53.16±24.07, and the skill level of correct interpretation of 54% of students was moderate. Also, there was no statistically significant difference between sex, academic year of the students, and the type of student with the mean of correct interpretation scores. Conclusion: Given that the skill level in interpretation of lung CT scan results among students was moderate, implementation of targeted interventions, including training courses for intern medical students and emergency medicine residents, is needed to increase their skills in correct interpretation of CT scan results.
